from abhyasa.sources import verbatimshow
Show an idea: the screen guide, the demos and the talks.
This module holds the ways that abhyasa shows an idea. It imports from all the modules above it. It has three parts:
- The screen guide: the board that the tutor draws over a page when you press Explain, its checks, and its three tiers of sources.
- Demos: the interactive figures and the 3D explainers from rupaka, with the ladder of lessons after a miss.
- Talks: a walk made into slides for a group, with the questions for the room.
Import the modules that this module uses. The heavy ones load inside the functions that need them, so the import stays light.
The screen guide
The screen guide: “I don’t get X”, answered with a board that the tutor draws over the page.
The learner looks at a walk step, a concept or a video, and says “I don’t get alpha bar”. The guide answers on the page, as a teacher does at a whiteboard. It circles the term, draws an arrow to a label in the figure, moves the slider of the demo, and speaks one short line for each step.
This module is the part of the guide that has no web page:
- the board language: a closed list of drawing commands, each tied to a thing on the page (an anchor), and the check of each line of the model’s reply;
- the context: what the page shows, cleaned and cut to size;
- the gate: the tutor answers at once when it is sure, else it looks in your vault, else on the web;
- the guard: no secret and no personal data leaves the Mac in a model call or a web query.
The board language, its checks and the page context are in rupaka.board. The guide block serves the board, and rupaka’s board.js draws it.
Import the helpers. The model layer and ramabana load only on the first call, so the import stays light.
The board language
The board is in rupaka: rupaka.board has the language of 14 commands, the check of each line (check_line), the whole reply (parse_board), the page context (clean_context), the video cues and the stream (stream_board). Its docs give each command and each rule. This module imports these names, so from abhyasa.show import parse_board works. GUIDE_KINDS is the old name of rupaka’s KINDS.
The trust of a quote
A quote of a step stays only when it is word for word in its source. abhyasa has its own rule for “word for word”: abhyasa.sources.verbatim also reads past the lines of page data, the Markdown marks and the row numbers of view_file. rupaka’s default rule is plainer. So each call of parse_board and stream_board in this module passes verbatim.
A quote of a source with Markdown marks stays with the rule of abhyasa. With the plain rule of rupaka, it drops:
mctx = by_id(dict(anchors=[], sources=[dict(title='DDPM', text='A **notable property** of the forward process is that it admits sampling x_t in closed form.')]))
step = json.dumps(dict(op='step', say='The paper says it.', src=1, quote='A notable property of the forward process is that it admits sampling'))
test_eq(parse_board(step, mctx, verbatim).steps[0]['quote'], dict(src=1, text='A notable property of the forward process is that it admits sampling'))
test_eq(('quote' in parse_board(step, mctx).steps[0], len(parse_board(step, mctx).dropped)), (False, 1))A small context for the tests: a passage, the DDPM formula with its tokens, a triangle figure with labels a and b, and a demo with the input t. vctx adds a video with three cues, shown is what the learner showed with the pointer, th is the thread of earlier turns, and TRY_RAW is the learner’s last graded try of the check.
DDPM = r'q(\mathbf{x}_t\mid\mathbf{x}_0)=\mathcal{N}(\mathbf{x}_t;\sqrt{\bar\alpha_t}\mathbf{x}_0,(1-\bar\alpha_t)\mathbf{I})'
ctx = by_id(dict(anchors=[dict(id='passage', kind='passage', text='It admits sampling x_t at an arbitrary timestep t in closed form.'),

vctx = by_id({**ctx, 'video': dict(id='abc123def45', cues=[[0, 'Today we add noise.'], [61.5, 'Alpha bar is the share of the signal that is left.'], [70, 'It falls as t grows.']])})

dict(kind='point', box=[480, 480, 520, 520], anchors=['passage'], t=800)]
th = [dict(said='I do not get alpha bar', says=['Alpha bar is the share that is left.', 'x' * 200], t='tutor'),
dict(said='why?', says=['Each step keeps a part of the signal.'], t='magic')]
TRY_RAW = dict(id='try', kind='try', text='Alpha bar grows with t.', answer='Alpha bar grows with t, because more noise is added.',
outcome='Not yet', feedback='Look at what each alpha is: a number below one.', error='Alpha bar does not grow: it is a product of numbers below one.',
gaps=['cumulative product', 'cumulative product', 'noise schedule'], state='open', left=2)Labels inside a figure
A figure is an image. Its labels (the “a” and “b” on the sides of a triangle) are not in the page text. The guide finds them once with a vision call and keeps their boxes for that figure. It keeps only the boxes, never the image.
figure_labels
def figure_labels(
vision, img:bytes, alt:str=''
)->dict | None:The labels in the figure image img, as text to a box from 0 to 1000, from the reply of vision(prompt, img, sp). None when the call fails or its reply is not JSON, so that no one keeps an empty result. A key in alt is masked here; vision_ask guards the full prompt for the model of its route.
FigureCache keeps the boxes in one JSON file, by the SHA-1 of the image bytes. A figure that changes gets a new key.
FigureCache
def FigureCache(
path, most:int=500, empty_ttl:float=86400.0
):The label boxes of each figure, by the SHA-1 of its bytes, in the JSON file path. It keeps at most most figures. An empty result is kept for empty_ttl seconds, and only when some figure in the file has labels: before that, an empty reply can come from a route that lost the picture, and the next post must ask again.
An empty result is not kept while no figure has labels. After one figure has labels, an empty result is kept, but only for empty_ttl seconds:
import tempfilefc = FigureCache(Path(tempfile.mkdtemp())/'figs.json', empty_ttl=60)
test_eq((fc.put('k1', {}), fc.get('k1')), (False, None))
test_eq((fc.put('k2', {'a': [1, 2, 3, 4]}), fc.put('k1', {}), fc.get('k1'), fc.get('k2')), (True, True, {}, {'a': [1, 2, 3, 4]}))
d = fc._all(); d['k1']['at'] -= 61; fc.path.write_text(json.dumps(d))
test_eq(fc.get('k1'), None) # too old: the next post asks againThe vision call goes through ramabana, on the job guide_vision: compose puts the image before the text, and the call runs only when the routed model takes a picture (accepts) and its route sends one (keeps_images). vision_why says in one line why the call does not run. The prompt and the system prompt pass guard for the model of each route, so a model on this Mac gets the text as it is. With a test model that has no routing, the call is a plain text call that passes guard for a hosted model, so a Fake can answer it.
rishi’s remote one-shot makes its message only from the parts that are dicts. So the raw image bytes and the text of compose do not get to the model, and the model answers a prompt with no figure. keeps_images finds this with no model call: it gives the same parts to the message code of the route and looks for the picture.
vision_ask
def vision_ask(
ask, name:str='', job:str='guide_vision'
):A vision call (prompt, img, sp) -> str on the ramabana job job (on the model of figure labels, by default the model of hints), or None when the routed model gets no picture (vision_why).
vision_why
def vision_why(
ask, name:str=''
)->str:Why the routed model of figure labels (name, else the model of guide_vision) gets no picture, or ’’ when it gets one. A test model with no routing gets one.
keeps_images
def keeps_images(
spec
)->bool:Whether the one-shot of the route spec sends the picture that compose puts in its prompt. Only rishi’s remote routes are checked; a check that fails counts as yes.
The system prompts of the guide hold no personal data, so refuse lets them go:
test_eq(guard(prompt('guide.figure'), mode='refuse'), prompt('guide.figure'))A vision reply that a test model gives:
from abhyasa.models import Fakef = Fake({'You find the text labels': dict(labels=[dict(text='a', box=[90, 400, 160, 500])])})
test_eq(figure_labels(vision_ask(f), b'\x89PNG', 'A right triangle'), {'a': [90, 400, 160, 500]})A vision call that fails gives None, not an empty result. The caller then does not keep it, and asks again the next time.
def down(p, img, sp=''): raise TimeoutError('the model timed out')
test_eq(figure_labels(down, b'\x89PNG'), None)A route whose message code drops the picture does not keep images. A route that makes the parts into a picture keeps them. A route of another kind is not checked:
from types import SimpleNamespace
from rishi.remote import RemoteChat, to_msg
from urai import mk_msgcloud, real = SimpleNamespace(runtime='remote'), RemoteChat._oneshot_args
try:
RemoteChat._oneshot_args = lambda self, p, sp, n: ([to_msg({'role': 'user', 'content': p})], {})
test_eq(keeps_images(cloud), False)
RemoteChat._oneshot_args = lambda self, p, sp, n: ([to_msg(mk_msg(p))], {})
test_eq(keeps_images(cloud), True)
finally: RemoteChat._oneshot_args = real
test_eq(keeps_images(SimpleNamespace(runtime='claude')), True)figure_check is the test of the Settings row Figure labels: it sends a picture with known labels and says which labels came back.
figure_check
def figure_check(
vision, img:bytes, want:tuple=('Encoder', 'Decoder')
)->fastcore.basics.AttrDict:Whether vision reads each label of want in the picture img: ok, the labels that it got, and the missing ones. Raise when the reply is not JSON.
A reply with both labels passes. An empty reply fails, and names the missing labels:
both = json.dumps(dict(labels=[dict(text='encoder', box=[50, 290, 420, 710]), dict(text='Decoder', box=[580, 290, 950, 710])]))
test_eq(figure_check(lambda p, img, sp='': both, b'\x89PNG').ok, True)
test_eq(figure_check(lambda p, img, sp='': '{"labels": []}', b'\x89PNG'), dict(ok=False, got=[], missing=['Encoder', 'Decoder']))The prompt
The system text says the rules of the board. The parts that change (the question, the page, the sources) come last in the request, so a provider’s prompt cache can keep the system text.
Step 1 marks the asked part with a circle or a box, and has at most one point for context. So a point never takes the place of the main mark.
test_eq(('mark the part that the learner asked about with a circle or a box' in GUIDE_SP, 'at most one point in step 1' in GUIDE_SP,
'Point at them when you name them' in GUIDE_SP), (True, True, False))A sketch is for a figure only, and a picture of an idea goes in the side panel: a diagram that the learner asks for is a panel, not marks on the passage. A question about the answer starts with the problem in it, and the final answer waits while tries are left:
test_eq(('only on a figure anchor' in GUIDE_SP, 'Never use sketch for a picture of an idea' in GUIDE_SP, 'the panel draws one' in GUIDE_SP), (True, True, True))
test_eq(('Step 1 names the problem in their answer' in GUIDE_SP, 'stop before the final answer' in GUIDE_SP,
'give the full worked solution' in GUIDE_SP, 'Step 2 explains' in GUIDE_SP), (True, True, True, False))
ex = [json.loads(l) for l in GUIDE_SP.split('An example reply', 1)[1].splitlines() if l.startswith('{')]
mine = [o for o in ex if o['op'] != 'v' and o.get('at', {}).get('a') not in ('m1', 'o1')]
test_eq([check_line(o, ctx) for o in mine], [''] * len(mine))A formula gets a day-to-day example in the spoken lines. Each line is one short sentence, and a code name is said as words:
test_eq(('day-to-day example' in GUIDE_SP, 'thrown ball' in GUIDE_SP, 'no semicolons' in GUIDE_SP, 'at most 20 words' in GUIDE_SP, 'Say a code name as words' in GUIDE_SP, len(GUIDE_SP) < 9000), (True,) * 6)A process is a side panel with numbered rows. The answer of a row is in to, and a head names no count. A panel has one shape: a table (which alone can have column names), a chain, a flow of boxes, a faded example, a wrong idea, or three stages. rupaka drops a line of another shape, so the prompt names each shape and when to use it. The title is the small line and the head is the big heading, so the prompt says which is which:
test_eq(('"numbered":true' in GUIDE_SP, 'the answer in "to"' in GUIDE_SP, 'no number in it' in GUIDE_SP), (True, True, True))
test_eq(('Give each panel one shape' in GUIDE_SP, 'Only a table has "cols"' in GUIDE_SP, 'and no "cols"' in GUIDE_SP, 'At most 6 rows' in GUIDE_SP), (True,) * 4)
test_eq(('"op":"node"' in GUIDE_SP, '"op":"edge"' in GUIDE_SP, '{"blank":"47"}' in GUIDE_SP, '"op":"myth"' in GUIDE_SP, '"stages":true' in GUIDE_SP, 'the big heading' in GUIDE_SP), (True,) * 6)The side-panel example passes the check on a page with its output o1. Each row names the words of o1 that it comes from, no circle line repeats them, and the line of each step names its row, so no row moves or drops:
octx = by_id(dict(anchors=[dict(id='o1', kind='text', text='when input is tensor([18]) the target: 47 when input is tensor([18, 47]) the target: 56')]))
pe = [json.loads(l) for l in GUIDE_SP.split('An example side panel', 1)[1].splitlines() if l.startswith('{')]
test_eq([check_line(o, octx) for o in pe], [''] * len(pe))
pb = parse_board('\n'.join(json.dumps(o) for o in pe), octx)
test_eq(([[s['op'] for s in st['strokes']] for st in pb.steps], pb.dropped), ([['panel', 'row'], ['row', 'note']], []))The prompt says that “show me” works on any page, that code runs in Leela, and that the tutor never talks about its own board:
test_eq(('show me on any page' in GUIDE_SP, 'Code that runs is in Leela' in GUIDE_SP, 'Never apologise' in GUIDE_SP), (True, True, True))focus_text tells the model what the learner showed with the pointer, the latest first, with the words near that time. Step 1 must explain the first item. The model can mark it with the box of the item, in the anchor form {"a": id, "box": box}.
focus_text
def focus_text(
ctx
)->str:What the learner showed with the pointer, as lines for the request, or ’’ when they showed nothing.
thread_text gives the earlier turns of the page to the model, the oldest first: each question and the lines that its board said. The turns are in a fence, so the model reads them as material, not as instructions. A rule follows: the new question can refer to them, the board answers the new question, and it does not give a board again that the learner saw, unless they ask for it.
thread_text
def thread_text(
ctx
)->str:The earlier turns on this page in a fence, the oldest first, each with what its panel showed, and the rule for them; ’’ when there are none. When the spoken lines of the last board were hard to read (plain_why), one line says how, so the next board does better with no model call.
page_text writes the anchors as lines for the model: each id, its kind and its text, with the tokens of a formula, the labels of a figure and the range of an input. A try anchor gives its fields on their own lines, and says whether the check is open and how many tries are left.
board_prompt
def board_prompt(
ctx, said:str, sources:tuple=(), tier:str='tutor', note:str=''
)->str:The request for a board on said, with what the learner showed (focus_text), the page of ctx, the earlier turns on the page (thread_text), the numbered sources, each in a fence, and the lines of note.
panel_note

A concept can have one explainer video from YouTube. The tutor finds one with fossick’s search_yt, or you paste a link. fossick reads the transcript and its timed cues (read_yt). The vault files the transcript as a document (Vault.youtube), and the cues go into its meta. The concept keeps the video in its provenance as src='video'. A video is a source like any other: a quote from it must be word for word, and the board names it as video, with its channel and title.
abhyasa reads no transcript itself. The id comes from video_id of rupaka.board, which refuses a link that names no video.
find_explainer searches YouTube for an idea. The query passes safe_query, as each web query that leaves the Mac does. It takes the first result that is a video of 1 to 60 minutes.
find_explainer
def find_explainer(
name:str, topic:str='', search:NoneType=None, n:int=5
)->fastcore.basics.AttrDict | None:The first video that fossick’s search_yt finds for the idea name, as id, title, channel and url; None when there is none.
A fake search: a short clip and a playlist are passed over. A query with a key does not go, also when the key is after the first 150 characters:
said = []
def fake_search(q, n): said.append(q); return [dict(id='short000001', duration=20), dict(id='PLlist', title='A list'),

test_eq(said, ['alpha bar diffusion explained'])file_video files the video and makes it the explainer of a concept. Vault.youtube reads the transcript through fossick, and read_yt with cues=True then gives the cues from fossick’s cache, with no second fetch. The link must be public (allow_private=False). A concept keeps one video: a new one takes the place of the old one.

fossick.core.read_yt, abhyasa.sources.public_url = realA board as a hint
On a page with an open check (the anchor check), a board counts as one hint on the check only when it is about the check (on_check): the learner showed the check with the pointer, or named it (“check”, “question”, “answer”, “hint”, “quiz”), or the main words of the question are words of the check (two of them, or all when there are fewer). The guide decides this before it asks, so it can tell the learner first. A board that does not count may not touch the check: the request says so (OFF_CHECK), and a stroke on the check drops. Then the learner keeps the hints for a real hint.
When the page sends the learner’s last try (the anchor try), a question about the try counts too: one that names the gaps, the try, a mistake, an error, what is wrong or the feedback (TRY_ASK), or a pointer on the try. Then the request says so (ON_TRY), and the model follows the rule for a question about an answer. A board that does not count gets no try.

asked_words
def asked_words(
s:str
)->set:The main words of s (ground.main_words) with a light plural stem, without the words that every question has.
A page with an open check on the cumulative share alpha bar:
chk = clean_context(dict(anchors=[*ctx.anchors, dict(id='check', kind='check', text='Why does alpha bar fall toward zero as t grows?')]))A question on the words of the check counts, and so does a question that names the check. An off-topic question does not:
test_eq(on_check(chk, "I don't get alpha bar"), True)
test_eq(on_check(chk, 'What does this question want?'), True)
test_eq(on_check(chk, 'Who wrote the Kamba Ramayanam?'), False)
test_eq(on_check(clean_context(dict(anchors=ctx.anchors)), "I don't get alpha bar"), False) # no open check: never a hintThe pointer on the check counts too, whatever the words:
test_eq(on_check(clean_context(dict(chk, focus=[dict(kind='point', box=[0, 0, 10, 10], anchors=['check'])])), 'what is this'), True)With the learner’s try on the page, “explain the gaps” counts. With no try, the same words do not:
tried = clean_context(dict(anchors=[*chk.anchors, TRY_RAW]))
test_eq((on_check(tried, 'explain the gaps'), on_check(chk, 'explain the gaps'), on_check(tried, 'Who wrote the Kamba Ramayanam?')), (True, False, False))The three tiers
The guide asks in up to three tiers, and the board shows which one it used:
- tutor: the page alone. When the model says that it is sure (
sureofSUREor more), the board draws at once. The passage on the page is source 1, so a quote from it shows as your source. - vault: else the guide searches your sources (
ground) and asks again with the passages that it finds. - web: else, when research is on, it searches the web, reads the pages, and takes a passage that is word for word in the page (
research.pick_passage, the gate of research). Then it asks one last time with that passage. The page goes into your vault, linked to the concept. The page says so at the end of the board, with Undo (unsave).
When no tier is sure, the best board so far shows, in the tutor’s own words.
video_source
def video_source(
v
)->dict | None:The video v (from video_of) as a source: its transcript, labelled video, with its channel and title.
guide_ask
def guide_ask(
ask, name:str=''
):The ask of the guide: the ramabana job guide on name, else on the model of the screen guide (by default the model of hints, a fast one), with guard for the model of each route (guarded); a test model as it is, with guard for a hosted model. A model that can stream keeps its stream(prompt, sp), with the same guard.
source_label
def source_label(
p
)->str:The label of passage p by its real source: your vault* for a vault shelf, else the label of its source, such as web.*
The guide uses the model that Settings names for the screen guide. With no model of its own, it uses the model for hints. Here a stand-in for RouteAsk gives the job and the model of each call.
from abhyasa.models import Routerclass Via:
"A stand-in for `RouteAsk`: each `ask` replies with its job and its model."
model = 'claude/sonnet'
def via(self, job, name='', cap=None, prepare=None):
f = lambda p, sp='': f'{job}:{name or self.model}'
f.model = name or self.model
return f
test_eq(guide_ask(Router(Via(), models=lambda: dict(hint='claude/haiku')))('hi'), 'guide:claude/haiku')
test_eq(guide_ask(Router(Via(), models=lambda: dict(hint='claude/haiku', guide='claude/opus')))('hi'), 'guide:claude/opus')
test_eq(guide_ask(Router(Via(), models=lambda: {})).model, 'claude/sonnet')Never caught unaware
The learner must always know what the guide does now, and where the text goes. So before each step of its work, explain sends a state event to on_state. The guide route sends each one to the page as it comes, and the page shows it in one line, the guide bar. The Mac overlay reads the same events. This is the one shape:
{"wait": "<one STE sentence>", "state": "reading" | "asking" | "searching" | "saving" | "drawing",
"model": "<model label>", "where": "on this Mac" | "hosted", "who": "<company of a hosted model, or ''>",
"query": "<the web query word for word, only for searching>", "sources": <count of vault passages or web pages that go to the model>}wait is always a full sentence, because an old page reads only wait. A field that does not apply is not in the event. explain sends asking, searching, reading and saving. The page itself shows reading for its own read, and drawing when the first step draws, so the route never sends a line that covers the board.
When the guide files a web page in the vault, explain sends {"saved": {...}} with the document and the concept link. The route gives the page {"saved": {"title", "url", "undo"}}, where undo is the POST route that takes the page and its link away again (unsave).
where_of (from abhyasa.models) tells who runs a model. It uses the label of model_label and the locality of ramabana (is_local, which knows the endpoint of an Ollama model). The model rows in Settings use the same function.
A Claude model is hosted by Anthropic. A model that the guide does not know counts as hosted:
test_eq(where_of('claude/sonnet'), dict(model='Claude Sonnet', where='hosted', who='Anthropic'))
test_eq(where_of(''), dict(where='hosted'))A model on this Mac sends nothing off the Mac, and the line says so:
test_eq(where_of('mlx/gemma-4-e4b-it'), dict(model='Gemma 4 E4B', where='on this Mac', who=''))
test_eq(_asks(where_of('mlx/gemma-4-e4b-it'))['wait'], 'Sends your question and the page text to Gemma 4 E4B. Nothing leaves this Mac.')
test_eq(_asks(where_of('claude/sonnet'), thread=True)['wait'], 'Sends your question, the page text and your last questions on this page to Claude Sonnet.')
test_eq(_asks(where_of('claude/sonnet'), f"Sends {_n(3, 'passage')} from your vault")['wait'], 'Sends 3 passages from your vault to Claude Sonnet.')web_sources is tier 3: it searches with a query that passes safe_query, reads at most 2 pages, and keeps a passage only when it is word for word in the page. A query that may not go gives no source. A search that gives no passage says so in a state event, and explain asks once more with NO_WEB when the best board asked for the web: so the board does not ask for the web that the guide already searched.
unsave
def unsave(
lr, s
)->int:Take back what the guide saved (s, from a saved event): the link of the page to the concept, and the page when the guide added it. The count of changes.
web_sources
def web_sources(
ask, ctx, said:str, search:NoneType=None, fetch:NoneType=None, lr:NoneType=None, on_state:NoneType=None
)->list:Sources from the web for said, each with a passage that is word for word in its page. on_state gets a state event before the search (with the query word for word), before each read and model call, and before the page goes into the vault. Then it gets {"saved": ...} when the guide added the page or its link to the concept: what unsave needs to take them away. When the web gives no passage, a state event says why (WEB_FAILED, WEB_NO_PAGE, WEB_NO_PASSAGE).
A key after the first 200 characters still stops the query: the guard reads the whole query before it is cut.

With a model that can stream, on_step(step, k) gets each step of a sure tutor board as soon as it is whole (stream_board). When the threading.Event stop is set, the stream closes and no next tier starts. hint is True when the board counts as a hint on the open check (on_check); the first state event says so.

test_eq((r.hint, evs[0]['hint'], evs[0]['wait'].endswith(COUNTS)), (True, True, True))An off-topic question does not count, the first event says nothing on hints, the request tells the model to keep off the check, and a stroke on the check drops:

test_eq((r.sources[0]['label'], evs[-1]['wait']), ('library', 'Sends 1 passage from library to the tutor.'))The tier and the end line come from what the board quotes. A sure vault board that quotes nothing is in the tutor’s words, with no source:
note = 'Alpha bar t is the product of the alphas up to step t, so it falls from one toward zero as t grows.'

evs = []
web_sources(None, by_id({}), 'alpha bar', search=lambda q, n: [], on_state=evs.append)
test_eq(evs[-1]['wait'], WEB_NO_PAGE)The board as it comes
stream_board is in rupaka.board. explain passes abhyasa’s verbatim to it.
A board takes some seconds to write. So the tutor tier streams it, and the first step draws while the model writes the next one. stream_board reads the reply as it comes. When a new line is in, it reads the whole lines so far again with parse_board, so the rules are the same as for a whole reply. When the header says sure of SURE or more, on_step(step, k) gets each step as soon as its spoken line and its first mark are in, and again each time it gets more strokes: so the first mark does not wait for the rest of the step (the rows of a side panel) or for the next step. The page adds the strokes that it does not have yet. A step that is not sure, or a reply with no header, sends nothing, and the guide goes on to the vault and the web as before. The board that stream_board returns is the truth: its first steps are the steps that went to on_step.
When the stream breaks after a step went out, the board keeps the whole lines that came, so the page does not lose what it shows.
The learner can stop: a newer question, Esc, or a closed tab. Then the guide route sets the threading.Event stop. stream_board reads no more chunks and closes the stream. So the model call ends at once, and the next question does not wait for the backend.
Chunked is a test model that streams its reply in chunks of 7 characters. It writes each chunk in events, and the test writes each step there too, so the order of the events shows when each step went out.
class Chunked(Fake):
"A `Fake` that can stream: `stream(prompt, sp)` gives its reply in chunks of 7 characters, and notes each one in `events`."

test_eq(r.steps[0]['strokes'], [dict(op='circle', at=dict(a='m1', tex=r'\bar\alpha_t'))])A tutor that is not sure sends no step. The board is the same as with a model that cannot stream:

test_eq(r.steps, explain(Fake({'Tier: tutor': three.replace('0.9', '0.4')}), dict(anchors=ctx.anchors), "I don't get alpha bar", web=False).steps)The stream of a test model passes the guard too: a key in the question never reaches the model.

min(d * 0.2, 80)px, the flight takesclamp(d / 800, 0.6, 1.4)s, and the easing is smoothstep. The pointer turns to its path and grows to 1.3x as it lands, then settles on a spring (response 0.4, damping 0.6). A mark draws from its tip. - The glow. A
boxis a soft ring and halo that blooms and then settles. It stays 10 px outside the text, so it never cuts it. - The marker. A
circleon a formula part or on words adds a wide marker stroke through the glyphs. Its blend mode comes from the surface under it:multiplyon a light surface,screenon a dark one. A white figure in dark mode still usesmultiply. - The chips. A
labelis a pastel chip with a coloured bar at its left, dark text in a sans font, and a thin leader line that ends in a dot on the part. Each label in a step has its own pastel. The chip pops in on a spring, and it never covers its target. - The strokes. Rings, underlines and sketches are perfect-freehand strokes with pressure, and they draw on as a pen does. An arrow is one light Rough.js stroke with a filled head. Marks from earlier steps fade to 45 %, and the glow of an earlier step goes.
- The side panel. The example of Explain is a card on warm paper at the top right of the window, in a hand font, with the values in monospace. Each step adds its row: the circle on the value on the page at its word, the curve from it 120 ms later, the row when the curve lands, then each cell 80 ms after the one before. Rows stay for the next steps; their curves fade. A new beat (a new
panelline) has its own title. While the panel shows, the page column moves left, so the panel never covers a mark. Below 1100 px the panel stands in the page, under the marked part. - The scroll. Before a step draws, the page scrolls its first mark into view when the mark is off screen or under the strip.
- The voice. Each word of the spoken line in the strip lights up when it is said.
- The state line. While the guide works, the strip shows one line: the
waittext of the latest state event, a chip that says on this Mac or hosted ·, the seconds after 3 s while the model writes, and Stop. Stop and Esc end the request, so the model stream closes. The caption of a board names its model, and has Voice off and Stop. The end shows what the guide saved, with Undo, and the hint line when the board counted as a hint on the open check. - The figure. The picture of a figure goes to the vision model only when the question is about it (the learner showed it, or the question names it), and the line says so first: “The guide sends this figure to
to find its labels.”
With prefers-reduced-motion, the pointer jumps to its mark, and the marks and chips fade in for 150 ms. Text from the model goes in with textContent only.
Host hooks: the board on another page
Leela and other hosts use the same board. play takes the hooks of the page in host. Each hook is optional, and the defaults keep the behaviour of abhyasa:
abhyasaBoard.play(board, {labels, fast, quiet, auto, host: {resolve, speak, demo, assets}})| Option | What it does | Default |
|---|---|---|
labels |
{anchorId: {label: [x0, y0, x1, y1]}}, the label boxes of a figure, 0 to 1000 of the anchor |
{} |
fast |
Draw each step at once, with no voice and no flight | false |
quiet |
No voice: the words are timed by their letters, and host.speak is not called |
false |
auto |
Go to the next step 1.2 s after the line is said | true (false when fast) |
host.resolve(id) -> Element\|null |
The element of anchor id. A formula element names its parts in data-parts: JSON [[tex, elementId], ...]. The board finds each part by its id in the element, then in the document. A token with no part element marks the whole formula |
document.querySelector('[data-guide-id="<id>"]') |
host.speak(text, onWord, done) |
Say text. Call onWord(k) when word k (from 0, split on white space) starts, and done() at the end. It can return a function that stops the speech. The board ignores calls after the step changes |
speechSynthesis, timed by letters when there is no voice |
host.demo(set) |
Move the demo to set, as {input: value}. A host demo must do its own gate check |
Rupaka.set on [data-guide-id="demo"], only when each gate is done, so the result never shows first |
host.assets |
The URL folder of rough.js and perfect-freehand.mjs |
'/vendor/' |
A host that gets the steps one at a time (the step events of the guide route) starts the board with step 1 and streaming: true, gives each next step to add(step), and gives the whole board to finish(board) at the end. The board waits at its last step until the next one comes. finish gives false when the steps that show are not the first steps of the whole board: then the host plays the whole board. A host that does not know these calls plays the whole board, as before.
abhyasaBoard.play({steps: [step1], tier: 'tutor', sources: [], streaming: true}, opts)
abhyasaBoard.add(step2) // true, or false when no streaming board shows
abhyasaBoard.finish(board) // true, or false: then play(board)A host with a rupaka demo gets its anchors from abhyasaBoard.demoAnchors(host), so that each host uses the same ids: demo for the demo, in:<bind> for each block whose bind is a key of spec.state, and out:<n> for each readout, caption, bars, pixels or plot block that shows, with n from 1 in the depth-first order of the spec. An id of more than 40 characters is dropped, never cut. The server never numbers these ids. clean_context only checks their shape.
abhyasaBoard.state gives {i, steps, tier, first, done, streaming}, and abhyasaBoard.pointer gives {tip, to, flying} in window pixels. Formula parts come from rupaka’s texparts.js (window.rupakaTex, also window.abhyasaTex): texParts, texAtoms, texWrap, and trust, the one KaTeX trust rule. A host loads rupaka.board.bundle() to mark its formulas the same way.
Show while you talk
While the learner holds Hyper+E or types in the box, they can show the part they mean with the mouse. guide.js keeps the pointer path in memory only while the guide asks: page pixels, at most 30 points a second, the last 15 s and 600 points. The ask takes the path, finds the gestures, and forgets the path.
| Gesture | Rule |
|---|---|
| circle | The path turns 300 degrees or more (and not more than 540) in 8 s, comes back near its start (20 px, or 35 % of the loop size), and its box is 24 px or more on each side |
| point | The pointer stays inside 12 px for 400 ms or more, after it came from 40 px or more away. A rest at the end of a circle is part of the circle |
| nothing | A small shake of a hand on the mouse, a swipe, a zigzag, an open arc, a small loop |
A circle selects the anchors that it covers most. A point selects the smallest anchor that holds it. A gesture on no anchor gets the element with text under it as a new anchor. The ask sends at most 5 items, the latest first, as ctx.focus: {kind, box, anchors, t, words}. box is from 0 to 1000 of the first anchor, t is in ms from the start of the question, and words are the last words in the box near that time. The Mac overlay sends the same shape, with the same rules (tests/data/gesture_paths.json holds the sample paths that both test).
While the learner draws, a faint trail of the last 1.5 s shows in the board ink, and a soft ring shows on each circle or point for 1.5 s. With prefers-reduced-motion, there is no trail, and the ring does not move.
Demos
Interactive demos on the learning shelf: store them, make them in the background after repeated misses, and log each prediction.
A demo is one interactive figure from rupaka. It asks the learner for a prediction first. It shows the result after the learner locks in the prediction. This module keeps demos on the learning shelf. Concepts and attempts are on the same shelf. The module decides when the tutor makes a demo. It runs that job in the background, so the learner never waits.
| rule | what happens |
|---|---|
| a miss on a concept that has a demo | the result of the question gets the demo, and the session shows it under the lesson |
two misses with a saved misconception, or a concept with visual: true in its meta |
the tutor queues a job: a model writes a demo, and rupaka checks it |
| the learner asks (“Show me a demo” on the concept page) | the same job starts immediately |
| a walk opens a step, and the next step has a demo or an order check | the job for the next step starts, so its demo is ready in time |
| a prediction in a demo | an attempt with kind='demo', and an answer to the learner model: depth 2, or depth 3 with a “why” line |
| the first miss after you saw a demo | the lesson uses another way, and the demo stays next to it |
| the second miss after you saw a demo | a simpler demo, or a job that makes one |
| the third miss after you saw a demo | nothing new: the next question steps back to a prereq |
Storage
A demo is one vault document. Its source is learning://demo/<slug>, its kind is demo, and its meta holds the spec.
| meta | value |
|---|---|
concept |
the slug of the concept, the link |
spec |
the rupaka spec |
schema, rupaka |
the schema of the spec, and the rupaka version that checked it |
by |
model:<name> or hand |
checked |
the time of the last passing check, or None |
aim |
'' for a demo, 'order' for an order check (the learner puts steps in order), 'simpler' for a simpler demo after a miss, or '3d' for a 3D explainer |
stats |
shown: predictions made; right: predictions that were right |
The text of the document is the title, the question, the gate prompts, the captions and the labels of the images, so hybrid search finds a demo.
demo_text
def demo_text(
spec
)->str:The searchable text of a demo: title, ask, gate prompts, captions and the labels of pixels images.
put_demo adds a demo, or replaces the demo with the same slug. It keeps the stats of the old demo. The vault keeps only one document for each text. So the text ends with the slug and the concept, and two demos with the same spec stay two documents. A model picks the id of a spec. When another concept, another aim or another ask already uses that id, put_demo puts the slug of the concept (and the aim, and the key of the ask) in front of the id. A lock keeps the check and the add together, so two demo jobs that run at once do not file under one slug.
Learning.put_demo
def put_demo(
spec:dict, concept:str, by:str='hand', checked:float=None, aim:str='', asked:dict=None
)->fastcore.basics.AttrDict:Store spec as a demo of concept with the aim aim. asked is the ask that the demo answers: {key, said}.
demo gets one demo by slug. demos lists the demos of a concept, newest first. demo_for gives the newest one. With an aim, demo_for gives the newest demo with that aim. So aim='' gives only a plain demo, never an order check or a simpler demo. A demo that the learner asked for (see Show me below) has the key of the ask. demo_for finds it only with that key, so the plain demo of a concept stays the same.
Learning.demo_for
def demo_for(
concept:str, aim:str=None, key:str=None
)->fastcore.basics.AttrDict | None:The newest demo of concept, or of concept with the aim aim; None when there is none. A demo made for an ask is found only by the key of its ask.
Learning.demos
def demos(
concept:str=None
)->fastcore.foundation.L:The demos of concept (or all demos), newest first.
Tests for storage
Make a shelf in a temporary vault, with one concept and the sandhi demo from the rupaka gallery.

test_eq((d.slug, d.concept, d.by, d.stats), ('vowel-sandhi', 'sa-sandhi-vowels', 'hand', dict(shown=0, right=0)))demo_for finds the demo by its concept. demos gives an empty list for an unknown concept. A search for the words of the caption finds the demo.
test_eq(lr.demo_for('sa-sandhi-vowels').spec, spec)
test_eq(lr.demos('nope'), [])
test_eq(lr.search('rule stops another starts', kind='demo')[0]['doc_id'], d.doc_id)The same id for another concept gets a new slug, so it does not replace the first demo.

test_eq(lr.demo('vowel-sandhi').concept, 'sa-sandhi-vowels')

lr.v.forget(o.doc_id)A demo is not a concept, so the list of concepts stays the same.
test_eq(lr.concepts().attrgot('slug'), ['sa-sandhi-vowels'])Predictions
The demo page sends each prediction. record_prediction stores it as an attempt with kind='demo'. The attempt has the gate, the pick, the right answer and the “why” line. It counts the prediction in the stats of the demo. A prediction also shows what the learner understands. So it goes to the learner model as an answer. The depth is 2 (recall), or 3 (explain) when the learner wrote why. The rules are the same as for a question. A right pick with high confidence is solid. A wrong pick with high confidence is a misconception.
The misses since a demo
A prediction changes the count of the demo ladder (see below), so the count comes first. since_demo reads the count from your attempts, and rung gives it as a number. You saw a demo when a miss got a demo in its result (the attempt has shown_demo), or when you made a prediction in a demo. A wrong prediction counts as the first miss, because you saw the demo before it. more adds misses that are not saved yet.
keep_rung puts the count on the concept as after_demo (None when no demo is in play). The model reads it: _back waits until the third miss since the demo, so the ladder runs before the step back.
keep_rung
def keep_rung(
learning:abhyasa.learner.Learning, slug:str
):Keep the misses since the demo on concept slug as after_demo, for _back in the model.
rung
def rung(
learning:abhyasa.learner.Learning, slug:str, more:int=0
)->int:The misses on concept slug since you last saw a demo of it, plus more; 0 when no demo is in play.
since_demo

)->fastcore.basics.AttrDict:File one prediction in demo slug as an attempt, count it for method, and update the learner model of its concept. meta goes on the attempt. With ask, the tutor’s grader reads the reason why against the core of the idea: only a right pick with a reason that passes counts at depth 3. The feedback names the reason, never only the key.
grade_why
def grade_why(
ask, c, question:str, picked, ans, why:str

test_eq(lr.demo('vowel-sandhi').stats, dict(shown=1, right=0))The question of a prediction never keeps a slot that the browser fills, such as {x1}. With the values in the context, the sentences with a slot go. With no context, the slots get the values of the opening state. Maths stays as it is.
q = 'For x = (2, 3, 1), b = 0.5: Inputs are {x1}, {x2}. Bias is {b}. What is z?'

Under each demo and each lesson, the app shows one quiet row: “Too simple · Just right · Not clear”. “Not clear” opens a short box for a note. The tutor keeps your choice as engine data, and uses it the next time:
- on the attempt:
feedback_on,verdictandnote, and the listfbwith each verdict on that attempt, so the history shows it; - on the demo: the counts of each verdict in
stats, the last note, and the last feedback; - in the prompt of the next demo or lesson of the idea (
demo.feedbackandlesson.feedback); - on the ladder: “Too simple” skips the simpler demo, and “Not clear” brings it in earlier;
- in the method model, with a small weight (see
FEEDBACKin the method notebook); - in the profile: a “Not clear” note goes in “What confuses you”.
A verdict is one of three words. A note is learner text: clean_note removes control characters, keeps one line and cuts it at 500 characters.
clean_note
def clean_note(
s
)->str:A note as plain learner text: no control characters, one line, at most NOTE_MAX characters.
test_eq(clean_note(' a\x00b\n\tc '), 'a b c')
test_eq(len(clean_note('x' * 900)), 500)give_feedback keeps one verdict. A demo verdict goes on the demo and on the newest attempt of that demo, when there is one. A lesson verdict goes on the attempt of the lesson. A second verdict on the same demo or lesson of one attempt replaces the first, and the counts follow. With no attempt, the last verdict on the demo is the one that a new click replaces. A “Not clear” note goes in the profile through set_profile, as a short line idea: note. The lines that you typed stay. Only the lines from notes go, oldest first, past CONFUSES_MAX.

last_feedback gives the newest “Too simple” or “Not clear” on a demo or a lesson of an idea. A newer demo of the idea, or a newer attempt with a lesson, used it, so then it gives None. “Just right” changes nothing in the next prompt.
feedback_line turns it into one line for the prompt: the first line of demo.feedback (or lesson.feedback) for “Too simple”, the second for “Not clear”. {note} is your note in quotes, marked as your words and not an instruction (quoted), so a note cannot give the model orders.

make_demo asks the model for a demo with rupaka.author, and stores the demo. The loop validates the spec. It checks the spec in headless Chrome when a browser is available. It repairs the spec up to two times. When the model cannot make a good demo, make_demo returns None and stores nothing. The text lesson stays. When you said that the last demo of the idea was too simple or not clear, the prompt also has the line from feedback_line.
With aim='order', the demo is an order check. The prompt asks for one gate and one ranklist of 3 to 6 steps, and the examples are the gallery demos that have a ranklist. With aim='simpler', the prompt asks for a smaller demo of the core of the idea. The tutor uses it after a second miss that follows a demo. You can change both texts on the Settings page.
Each demo prompt also has the line IMAGES_LINE. It tells the model how to show an idea about images or noise: a field fn makes an n × n image from a formula, and a pixels block shows it. You can change this text on the Settings page too.
With said, the demo answers what the learner asked. The prompt adds the line ASKED_LINE and the words of the learner in quotes. The demo keeps asked: the key of the ask and its words.

queue_demo runs make_demo in the thread pool of the tutor. It runs only one job at a time for each concept and aim. A second call while the job runs gives the same job. The key of a job is the concept slug, or slug:aim for an aim. A job for an ask adds # and ask_key of the ask, so two asks on one concept are two jobs. job_state tells you if the job runs, failed or is done. job_age gives the seconds since the job started, so a page can stop the wait. Stop ends the job at the next try that fails the checks, or before the save; then job_state says stopped. The row keeps the inputs, so Do it again makes the same demo again.
Each job has a row in abhyasa.learner (job_key): the activity chip lists it, and the card of the demo loads again on its event. The said line of the row is the stage in STAGES, so the card changes when the model starts to write and when a try fails the checks. A try that fails the checks is a normal step, not an error: the tutor writes the demo again. _Tries logs the first 3 errors of each such try at INFO, with the key of the job, and keeps them on the row as tries, so the card can say why in a small fold. A job that starts by itself, such as the demo of a walk step or a simpler demo, is quiet: it has a row, but the chip does not list it.
job_stage
def job_stage(
tutor, slug:str, aim:str='', said:str=''
)->str:The real stage of the demo job of slug: ‘queued’ (another job runs first), ‘writing’ (the model writes the spec), ‘fixing’ (a try failed the checks, and the model writes it again), or ‘none’.

Sometimes you see a demo and still miss the idea. Then the tutor goes one rung down a short ladder. It counts only your misses on the idea since you last saw a demo of it. A pass ends the count.
| misses since the demo | what the tutor adds |
|---|---|
| 1 | a lesson in another way, from the method model: never demo, and never the way that just failed. The demo stays next to it. |
| 2 | a simpler demo (the aim simpler), or a job that makes one |
| 3 or more | nothing new. _back in the model sends the next question to the weakest prereq that is not learned. |
The setting checks.demo_ladder turns the ladder off. Then a miss gets the plain demo, as before.
since_demo, rung and keep_rung (in the section on predictions) count the misses since the demo.
backed is true when _back sends the next question on the concept to a prereq. After a demo, that is after the third miss since the demo. From then on, the ladder starts no job. So the ladder and the step back do not pull two ways.
backed
def backed(
learning:abhyasa.learner.Learning, slug:str, goal:int=None
)->bool:True when _back sends the next question on concept slug to a prereq.
other_way picks the way of the lesson on the first rung. It asks the method model for your best text way, as for a weak concept. It leaves out the way that failed. demo is never a text way. failed can also be a list of ways. lesson_way is in LESSON_HOOKS of the tutor. So the tutor writes its usual lesson after the miss, in the other way. A pass on the check of that lesson credits that way. When you said that the demo was too simple, the second miss gets a lesson in another way too, in place of the simpler demo.
lesson_way
def lesson_way(
tutor, q
)->str:The way of the lesson on the first miss after a demo, and on the second when you said that the demo was too simple; ’’ on another miss, or when the ladder is off.
other_way
def other_way(
learning:abhyasa.learner.Learning, slug:str, failed:str=''
)->str:The best text way for you on concept slug by the method model; never demo, and never the way or the ways failed.
simpler_demo is the second rung. When you said “Not clear” after the newest simpler demo was made, it makes a new one, so your note goes in its prompt. It gives the newest simpler demo, or it queues a job for one. Once _back steps back, it queues nothing.
simpler_demo
def simpler_demo(
tutor, slug:str, first_error:str=''
)->fastcore.basics.AttrDict:The second rung for concept slug: demo, the newest simpler demo; else demo_pending and a queued job; else nothing, once _back steps back. After “Not clear”, an older simpler demo does not count.
A walk has no tutor question after a wrong prediction. demo_lesson uses the same lesson path for a prediction: the gate is the question, and the right pick is the answer. The check of the lesson comes next on the concept, in the way of the lesson.
The tutor hook
on_close runs after each question closes (it is in CLOSE_HOOKS). A pass adds nothing. After a miss, it goes down the demo ladder when you saw a demo of the concept:
- the first miss keeps the plain demo next to the lesson, which
lesson_waywrote in another way; - the second miss gets a simpler demo, or
demo_pendingwithdemo_aim='simpler'; - a later miss gets nothing new, and
ladderin the result says which rung it is.
Your feedback on the demo changes two rungs. After “Too simple”, the second miss gets no simpler demo. After “Not clear”, the first miss already gets the simpler demo.
Else, it attaches the newest plain demo of the concept to the result, and marks the attempt with shown_demo. An order check or a simpler demo is not a plain demo, so on_close does not use it here. When there is no demo yet and the concept wants one, it queues the job. Then it marks the result with demo_pending.
on_close
def on_close(
tutor, q, r
):After each close: keep the misses since the demo on the concept, and after a miss, go down the demo ladder.
Tests for the hook

The learner can ask for a demo at any time: with the button “Show me” (⌥E) on a walk step or in a session, or with “show me …” in an answer box. The demo comes from what the learner asked, not only from the concept. So two asks on one concept give two demos.
This section has the parts that the app uses: show_ask reads an ask in an answer box, demo_kind picks the kind of demo, can_explain says if 3D explainers are ready, explainer_for makes a 3D explainer, and each ask is filed as a document, so the course can read it.
show_ask gives the words after “show me” at the start of a text, or '' for a bare “show me”. “I want to see”, “let me see”, “show it to me” and “play it” ask for Show too. A short lead such as “yes”, “ok” or “please” can come first, as a spoken reply to “Say show me” does. For any other text it gives None. So an answer box can send an ask to a demo, not to the grader.

demo_kind picks one of three kinds for an ask. A plain “show me” gets a 2D demo with a prediction first (demo). A 3D explainer (explainer) comes only when the learner says “3D”, or for a physical thing. Leela (notebook) comes only when the learner says “try” or “code”, or when the ask names a library. The result also has why: one line that the page shows. Only rules decide. There is no model call, because a plain ask always gets a 2D demo.
demo_kind

With an older rupaka, the app shows “Show it in 3D” as not ready. It does not make a fake 3D demo.

def can_explain()->bool:True when the installed rupaka has the scene block and the top-level key mode, so it can make a 3D explainer.
The result is the same as what the installed rupaka has. The test needs these imports.
from rupaka.spec import TOP, manifeststest_eq(can_explain(), 'mode' in TOP and 'scene' in manifests())3D explainers
A 3D explainer is a rupaka spec with "mode": "learn" and one scene block. The scene has bodies, forces, labels and camera shots, and it builds in 3 to 6 steps, with one spoken line for each step. There is no gate, so the learner sees the thing at once. The learner gets one when they say “3D”, when the ask is about a physical thing, or when they click “Show it in 3D” under a 2D demo.
The model writes the spec. It never writes code. The prompt has the rules of an explainer, the manifests of the scene blocks from rupaka, and one good example. rupaka’s validate checks the spec, and the model gets one try to repair it. When the second spec also fails, abhyasa says so and shows the 2D demo.
scene_catalog takes the part of rupaka’s catalog that a scene needs: the scene blocks, a caption, and the expr fn for a derived size. The prompt gets only these, so the model does not add a gate or a slider.
scene_catalog
def scene_catalog()->str:The scene blocks and the expr fn from rupaka’s catalog, as text for the prompt.

put_ask files one ask as a document of kind ask: the concept, the words of the learner (said, empty for the button), the text that the demo is made from (ask), its key, the kind, the place (where: walk, session, guide or concept) and where on that place (walk and step, or session). An ask never moves the learner model. A prediction in the demo of an ask keeps the id of the ask as asked, so asks can give the outcome.
An ask with no words and no open check has no key: its demo is the plain demo of the concept. asked gives one ask by its id.
An ask can have an aim: simpler for the simpler demo of the ladder. asks gives the asks, newest first, in the form of the course record: {id, at, where, said, ask, concept, slug, kind, outcome} and the place. slug is the demo of the ask, when it is made. For an ask of the kind explainer, it is the 3D explainer. outcome is right or wrong from the first prediction on the demo of the ask, else empty. The course reads this list. It can filter by concept, walk or session.

show is the one engine of a demo that you ask for. Each place calls it: Show me (⌥E), “show me …” in an answer box or to the guide, and the Show slot of a concept page. The wait under a lesson after a miss is an ask too. It files one ask (put_ask), picks the kind (demo_kind, or kind demo or 3d when the learner picked one), and starts the job (queue_demo) when the shelf has no demo for the ask. It never says no: with no demo yet, the job makes one, and the card waits for it. A notebook kind starts no job, because code runs in Leela. aim='simpler' asks for a simpler demo. After “Not clear”, it is always a new one.

A walk as a talk for a group: the deck shape, its checks, a talk made from a walk, the run log and the recap.
A presenter can give a walk to a group. The talk is a list of slides. Each slide shows a part of the walk, one beat at a time, and it can have one question for the room. This module is the engine of a talk: the shape of a deck, the checks of that shape, the questions, a talk made from a walk, the store calls, the public deck that the room sees, the run log, and the recap after the talk. It imports no web code, so Leela can use the same shape and checks.
The imports are light: the standard library, the store, the walk paths (journey), the demos, the model calls, the prompts and the settings.
What a talk is
A talk is a document on the learning shelf, of kind talk. It points at its walk in src and copies what it shows, so a change to the talk never changes the walk. minutes is the slot of the presenter. phones is the choice “Room phones”. live is the id of the run that is open now, or None.
These names give the shape. A slide has one of SLIDE_KINDS, and a question has one of ASK_KINDS. A talk from a notebook (talk_from_sources) starts with a poll slide and ends with a next slide. A poll asks the room about itself, so its choice has no right answer. A next slide keeps the file:// link of the notebook in link.

def on_stage(
t:dict
)->dict:Talk t with no parked slide: the talk that Present gives.
parked
def parked(
s:dict
)->bool:True when slide s is parked: its idea left the walk. The room never sees it, and it takes no minutes.
Slides and beats
Each press of D shows one beat more. passage, body, figure and demo show a part of the slide. ask opens the question. body is a short list of points that the tutor writes for a slide that has no passage. lit:<text> lights a text in the passage, and lit:#<id> lights a part of the figure or the demo. Leela adds lines:a-b and out for its code slides.
A beat that shows a part needs that part on the slide. This table gives the part for each beat.
A figure is an image id, never a path or a URL: asset:<path in the vault assets>. An id with another scheme, a .. part, a leading /, a backslash, a second : or a control character is refused.
The body of a slide is a list of at most BODY_MOST points. Each point is a short text.
A list of short points is a good body. A text, or too many points, is not.
assert _body_ok([]) and _body_ok(['Scores become weights.'])

A choice needs 2 to 6 options and the index of one of them. On a poll slide, a choice has no answer. An order needs the indexes of all its options, each one time. A run question (“What does this print?”) has 2 to 6 options or none, and no answer before the run.
_beat_problems checks the beats of one slide against what the slide shows.
A text field that you write can hold no control mark and no direction mark (CTRL of abhyasa.path): a mark can hide text or turn it around on the screen. clean_slide strips them from the fields of a slide, and check_talk refuses a slide that still has one. A passage is the word-for-word text of a source, so it stays as it is.

One slide can give more than one problem. A good talk gives []. It never raises, so a host can show the problems of a talk from a file.
check_talk
def check_talk(
t:dict, schemes:tuple=('asset',)
)->list:The problems of talk t; [] when the talk is good. It never raises.
TALK_CASES holds a good talk and one changed copy of it for each problem, with the problems that each must give. Leela runs the same cases on its own copy of the checks.
A talk that is not a dict, or a slide with odd values, gives problems and does not raise.

["['x']: unknown ask kind 'poll'", "['x']: unknown beat 'fly'"]Questions for the room
A demo gate with fixed options can be a room question with no model call. ask_from_gate and public_ask are thin wrappers over rupaka.poll.of_gate and rupaka.poll.public, so the rules come from rupaka. The options are a list, or {"from": path} in the state of the spec. The answer is {"is": value}, or a path in the state. A path that is not in the state (it needs derive) gives None, and so do fewer than 2 or more than 6 options. The prompt and the options are written as the drawn gate shows them, so the room reads the same text as the demo on the screen: 2.0 shows as 2, a minus is the sign −, a number has at most 4 digits after the point (or the digits that a {path:2} field gives), and None shows as empty.
ask_from_gate gives a choice from gate gate of spec, or None.
ask_from_gate
def ask_from_gate(
spec:dict, gate:str
)->dict | None:A choice question from the gate gate of spec, with the index of the right option; None when the gate can not be a room question.
public_ask keeps only what the room can see: the kind, the question, the options, and the most characters of a words answer.
public_ask
def public_ask(
ask:dict | None
)->dict | None:The part of ask that the room sees: no answer and no source.
A short check becomes a choice of 4 options through one model call, with the prompt talk.choice. The answer stays in the talk. When the call fails, or the reply is bad, the question is a words question.
_choice gives the reply as a choice when it has a question, 4 different options and the index of one of them, else None.
When there is no choice question, the slide asks for a short answer in words. words_q writes it from the name of the idea, and never changes the case of the name. A name that reads as a question (it ends with ?, or it starts with Why, How, What, When or Which and has more words) is the question. Any other name goes in quotes after “what is”, so a name such as “CAN bus” reads well. An empty name gives no question (None).
words_ask
def words_ask(
name:str
)->dict | None:The words question on the idea name as a question for the room, or None for an empty name.
old_words_q
def old_words_q(
name:str
)->str:The words question that talks made before words_q: the name always after “what is”.
words_q
def words_q(
name:str
)->str | None:The words question on the idea name: the name itself when it reads as a question, else what the idea is; None for an empty name.
A name with maths that is a question keeps its maths and its case:
test_eq(words_q(r'Why scale by $1/\sqrt{d_k}$'), r'Say in one or two sentences: Why scale by $1/\sqrt{d_k}$?')A name that ends with a question mark stays as it is. A plain noun phrase goes in quotes, with its case. A question word alone is a plain name, and an empty name gives no question:
test_eq(words_q('How does attention work?'), 'Say in one or two sentences: How does attention work?')
test_eq(words_q('Bayes?'), 'Say in one or two sentences: Bayes?')
test_eq(words_q('CAN bus'), 'Say in one or two sentences: what is "CAN bus"?')
test_eq(words_q('WHO growth charts'), 'Say in one or two sentences: what is "WHO growth charts"?')

test_eq(words_q('whenever'), 'Say in one or two sentences: what is "whenever"?')
test_eq(words_q(''), None); test_eq(words_ask(' '), None)ask_from_check makes the call with the model task talk. ask_for_concept does the same with the statement of the idea as the passage.
ask_for_concept
def ask_for_concept(

ask_from_check
def ask_from_check(

)->dict | None:A choice question on concept slug from one model call (and one more when its words are not plain, plainly), or a words question when the call fails (None when the idea has no name).
A choice question whose words are hard to read is written again in plain English, in one more call:
lrq = temp_learning(); sq = lrq.put('Noise schedule', 'The schedule says how much noise each step adds.', 'ml').slug
hard = 'Which option leverages the schedule; which one is fixed?'
fk = Fake({'Write these texts again': {'q': 'Which part is fixed before training?'}, 'Idea:': dict(q=hard, options=['A', 'B', 'C', 'D'], answer=0)})
test_eq((ask_from_check(lrq, fk, sq)['q'], len(fk.calls)), ('Which part is fixed before training?', 2))Minutes
A slide with a question takes the minutes of its walk step plus talks.ask_min. The talk takes the sum of its slides, except the parked slides (parked).
talk_minutes
def talk_minutes(
t
)->int:The minutes of the slides of talk t that are not parked.
slide_minutes
def slide_minutes(
step:dict, ask:dict | None
)->int:The minutes of the slide of walk step step with the question ask.
A talk from a walk
Each walk step that is not skipped gives one idea slide. A demo or an order check takes its question from the first gate of the demo that can be a room question. A step with no demo, or with no such gate, uses its passage and a short check. A code check gives a words question, because a talk never runs code. A passage with a small code cell that prints a value gives a run question: “What does this print?” with the code. The room answers before the presenter runs the cell. With “No code”, a slide has no demo and no question on code.
print_cell finds that code cell in the passage. A small cell has at most RUN_MOST simple statements. It prints a value when it calls print, or when its last statement is a value. A cell that draws a picture does not count. print_cell gives the cell as one line of code.
print_cell
def print_cell(
text:str
)->str | None:The first small code cell in the markdown text that prints a value, as one line of code, or None.
A cell that prints, or that ends with a value, counts. An import, a cell that draws, a loop and a long cell do not count.
test_eq(print_cell('Add two numbers.\n\n```python\nx = 2\nprint(x + 3)\n```'), 'x = 2; print(x + 3)')
test_eq(print_cell('```python\nimport torch\n```\n\n```python\nxs = [1, 2]\nlen(xs)\n```'), 'xs = [1, 2]; len(xs)')
test_eq([print_cell(f'```python\n{c}\n```') for c in ('import torch', 'show_images(xs)', 'for i in range(3):\n print(i)', 'a = 1\nb = 2\nc = 3\nprint(a)')], [None] * 4)
print_cell('```python\nprint(2 + 3)\n```')code_piece gives the one short piece of code that a notebook slide shows: the first small code cell of the section, with no blank lines. A cell of imports only, a cell that draws and a long cell do not count. A cell with a line longer than cols characters does not count either: the room cannot scroll, and at the least size of slide code such a line passes the right edge of the slide. A slide whose code is beside its points, a figure or a demo has room for CODE_COLS characters, and code alone has room for CODE_COLS_ALONE.
code_piece
def code_piece(
text:str, cols:int=50
)->str:The first small code cell in the markdown text (at most CODE_LINES lines of at most cols characters, not imports only, no picture), as a ```python block, or ’’.
The import cell does not count, so the piece is the next cell, with its blank line gone. A long cell gives no piece. A cell with a line that is too long for the slide gives no piece, so the next cell is the piece.
test_eq(code_piece('Setup.\n\n```python\nimport os\n```\n\nRun it.\n\n```python\nx = 2\n\nprint(x + 3)\n```'), '```python\nx = 2\nprint(x + 3)\n```')
test_eq(code_piece('```python\n' + '\n'.join(f'a{i} = {i}' for i in range(9)) + '\n```'), '')
test_eq(code_piece('No code here.'), '')
wide = '```python\nx = ' + 'a' * 70 + '\nprint(x)\n```\n\n```python\ny = 1\nprint(y)\n```'
test_eq(code_piece(wide), '```python\ny = 1\nprint(y)\n```')
test_eq(code_piece(wide, CODE_COLS_ALONE), '```python\nx = ' + 'a' * 70 + '\nprint(x)\n```')_idea_ask gives the demo slug (or None) and the question of one step.
_idea makes the slide of one step. Its beats show the passage, then the figure, then the demo, each when the slide has it. The slide keeps the source of its passage, so the editor, the room and the recap file can name it. A section of a notebook (a step whose passage has cells) is not a slide as it is: its headings, code and tables are too much for a room. So the whole section goes to the slide writer in _read, and the slide shows only the short piece of code_piece (none with “No code”), the points that the writer makes from the section, and the question. The run question still comes from the whole section. With “No code”, another passage that has code does not show either. The slide writer gets it in _read and says in words what the code does. _unread takes _read away before the talk is saved.
shown_step
def shown_step(
s:dict, passage:str
)->dict:Step s as its slide shows it, for its minutes: a slide that explains a section of a notebook shows only passage and has a question, not the hands-on check of the walk.
hands_on
def hands_on(
s:dict
)->bool:Whether the check of walk step s is hands-on work (a notebook or code), which a room does not do during a talk: its slide asks a question in its place.
What the slides say
A walk from a paper or a link gives each slide a passage. A walk from a topic does not: its steps have no passage, and the tutor note of a step comes only when a learner opens the step. So the tutor writes the content of each slide when the talk is made. A slide with no passage gets 2 to 4 points for the room. Each slide with no speaker note gets one: what to say, one question to ask the room, and one common confusion to watch for. A slide with a passage keeps it, and gets only the notes.
The prompt talk.slide asks for both, with one model call for each slide. You can change it on the Settings page.
_body gives the reply as points and notes, or None when it is bad. slide_notes writes the notes as Markdown.
slide_notes
def slide_notes(
b
)->str:The speaker notes from the reply b: what to say, a question for the room, and a confusion to watch for.
needs_fill is True for an idea or a primer slide that has no passage and no points, or no speaker note. A slide that shows only a piece of a section (_read) needs points too (_pointless).
needs_fill
def needs_fill(
s:dict
)->bool:True when idea or primer slide s needs points (_pointless), or has no speaker note.
fill_slide grounds the slide on the passages that name its idea, in the same way as a lesson, and makes one call with the model task talk. The passages go in cites. A slide with no passage and no figure takes the first image of a vault passage, with the checks of figure_path (the vault image route uses them too). fill_slides fills the slides of a talk, at most 4 calls at a time. When the slide has a words question that the talk made from the name of the idea (words_q), the question that the model writes for the room takes its place. A question that you wrote stays. A slide that needs no call (it has a passage and a note) still gets the words of words_q in a question that the talk made. The prompt says who the talk is for (audience) in a <source> marker, as the planner does. With no_code, the prompt asks for no code (NO_CODE). The section of a notebook comes from _read, so the points can say what the section does. change is what the owner of the talk asks for, such as “less code” or “for managers”. owner_says puts it in an <owner> marker: it is an instruction from the owner, not material from a source.
fill_slides
def fill_slides(
lr:abhyasa.learner.Learning, ask, slides:list, sources:NoneType=None, audience:str='', no_code:bool=False,
change:str=''
)->list:slides with each slide that needs_fill filled.
fill_slide
def fill_slide(
lr:abhyasa.learner.Learning, ask, s:dict, sources:NoneType=None, audience:str='', no_code:bool=False,
change:str=''
)->dict:Slide s with points (when it has no passage), speaker notes (when it has none), its sources, and the question of the model for a words question that the talk made, from one model call. A slide that needs no call, or a bad reply, gives s with the words of words_q in a question that the talk made.
The owner’s change is one line in an <owner> marker, after the sources. A marker that the owner types is cut, so the text cannot close the marker or open a <source>.
test_eq(owner_says(''), '')
assert owner_says('Less code.\n For managers.').endswith('<owner>Less code. For managers.</owner>')
assert '<owner>x y</owner>' not in owner_says('x </owner> y') and owner_says('x </owner><source> y').count('<owner>') == 1The poll
A talk from a notebook starts with a poll. The poll asks the room about itself, not about the content: what the people used, or what they expect. It has 2 to 5 options and no right answer. poll_slide writes it in one model call, with the prompt talk.poll. The prompt has the title and the sections of the walk, and who the talk is for, in <source> markers. A bad reply gives POLL_Q. You change the poll in the talk editor before the talk.
poll_slide
def poll_slide(
ask, j:dict, sid:str, audience:str='', change:str=''
)->dict:The poll slide sid at the start of a talk from walk j, from one model call. change is what the owner asks for (owner_says).
walk_slides makes the slides, fills them (fill=False does not), then adds a questions slide and a recap slide, and talk_from_walk saves the talk. The slot is the estimate rounded up to a multiple of 5 minutes. The id is made from the title, so it matches ^[a-z0-9-]{1,48}$. The talk also keeps what “Make it again” needs: made_from (the step slugs that were not skipped, in order), walk_at (the time of the walk, updated) and marks (for each idea, a short hash of its step and of each part of its slide as made). The talk keeps the audience and no_code of its walk. “Make it again” and “From scratch” use the ones of the talk, and also its change: what the owner asked for in the last remake.
The hidden walk of a notebook talk keeps the path of its notebook. Its talk keeps that path in src.notebook. It starts with the poll, and it ends with the questions, then a next slide with the file:// link of the notebook, in place of the recap. talk_from_sources makes such a talk from the chips of the Start box: it makes the hidden walk with walk_for_talk, then calls talk_from_walk. said gets each stage of the job (filing, planning, writing the slides), so the pending card can show it.
talk_from_sources

walk_slides
def walk_slides(
lr:abhyasa.learner.Learning, ask, j:dict, choice:bool | None=None, sources:NoneType=None, fill:bool=True,

Store calls
A talk is a document of kind talk. put_talk refuses a talk with problems, and replaces an earlier talk with the same id.
Learning.put_talk
def put_talk(
t:dict
)->fastcore.basics.AttrDict:Save talk t, and replace an earlier one with the same id. A talk with problems raises ValueError.
talk gives one talk by id, and talks gives all of them with the newest first. drop_talk deletes a talk and all that is part of it: its runs (the recap comes from a run, so it goes too), its history of changes, and the side walks that it opened beside its slides, with their own side walks. A talk from your sources has a hidden walk (walk_for_talk), and that walk goes too. The walk of your own that a talk was made from, your answers and what you learned stay. The public deck and its images are made from the talk each time, so nothing of them is kept.
Learning.drop_talk
def drop_talk(
tid:str
):Delete talk tid with its runs, its history of changes, the side walks that it opened beside its slides, and its hidden walk (walk_for_talk). A walk of your own stays.
Learning.talks
def talks()->fastcore.foundation.L:All talks, the most recently changed first.
Learning.talk
def talk(
tid:str
)->fastcore.basics.AttrDict | None:One talk by id. A slide of an old talk gets the source of its passage (_old_sources), and code that fits the slide (_fit_code).
code_wide
def code_wide(
passage, cols:int
)->bool:Whether a code fence in passage has a line longer than cols characters.
code_cols
def code_cols(
s:dict
)->int:The longest line of code that slide s has room for: CODE_COLS beside its points, a figure or a demo, else CODE_COLS_ALONE.
_fit_code checks the code of each slide when the talk loads, so a slide that was made before the check has code that fits too. A slide with code that is too wide and points shows its points with no code. In a passage with words and code, only the code that is too wide goes:
old = AttrDict(slides=[dict(id='s1', kind='idea', step=0, concept='x', beats=['body', 'passage'],
show=dict(body=['A point.'], passage='```python\nx = ' + 'a' * 70 + '\n```'))])
s1 = _fit_code(AttrDict(journey=lambda i: None), old).slides[0]
test_eq((s1['show']['passage'], s1['beats']), ('', ['body']))
test_eq((code_wide('```python\n' + 'a' * 51 + '\n```', CODE_COLS), code_wide('```python\n' + 'a' * 50 + '\n```', CODE_COLS)), (True, False))
mixed = AttrDict(slides=[dict(id='s1', kind='idea', show=dict(passage='Some words.\n\n```python\nx = ' + 'a' * 120 + '\n```\n\nMore words.'), beats=['passage'])])
test_eq(_fit_code(AttrDict(journey=lambda i: None), mixed).slides[0]['show']['passage'], 'Some words.\n\nMore words.')fill_talk fills the slides of a talk that was made before the tutor wrote slide content: the button “Fill the slides” in the editor calls it. A slide that changed while the tutor wrote keeps the change. The fill is one change in the history of the talk (“Filled the slides.”, by the tutor), so Undo can take it back. The model calls run first; the save and its history row then run as one step under edit_lock.
fill_talk
def fill_talk(
lr:abhyasa.learner.Learning, ask, tid:str, sources:NoneType=None
)->fastcore.basics.AttrDict:Fill each slide of talk tid that needs_fill, and save the talk with one history row. A slide that changed while the tutor wrote keeps the change.
walk_talk gives the newest talk that a walk was made into.
walk_talk
def walk_talk(
lr:abhyasa.learner.Learning, wid:str
)->fastcore.basics.AttrDict | None:The newest talk made from walk wid, or None.
Make it again
A walk can change after you make a talk from it: you add, remove, skip or move ideas, or change a note or a passage. “Make it again” brings these changes into the same talk, and keeps your edits. It matches a slide to a step by the concept slug, never by its place.
- A slide whose idea is still in the walk keeps each part that you changed. A part that you did not change takes the new walk, when the step changed.
- A new idea gets a new slide, at its place in the walk.
- A slide that you added (a pause, questions, a primer) stays after the slide that it followed.
- A slide whose idea left the walk moves, in its order, to the end, in the section “Not in the walk any more”.
- An idea whose slide you removed stays out.
Your edits are the parts that changed since the talk was made. Each part of a slide as made has a short hash in marks. A part whose hash is not the same now is yours. (The history of the talk is not used for this: it keeps at most 50 changes, and a change of a passage or of more than one field names no field.) A talk made before 0.0.14 has no marks, so each of its slides stays as it is.
slide_marks gives the hash of each part of a slide, and step_mark the hash of the parts of a walk step that a slide uses.
step_mark
def step_mark(
st:dict
)->str:The short hash of the parts of walk step st that its slide uses: the passage and its source, the note and the check.
slide_marks
def slide_marks(
s:dict
)->dict:The short hash of each part of slide s (SLIDE_PARTS).
walk_changes counts the ideas that the walk added, removed and moved since the talk was made, and the ideas whose note, passage or check changed in the walk (by the step hash in marks, for an idea that still has its slide). A skipped idea counts as removed. An idea counts as moved when it is not in the longest run of ideas that keep their order (difflib). An old talk with no made_from, or a talk whose walk is gone, gives all zero.
walk_changes
def walk_changes(
lr:abhyasa.learner.Learning, t:dict
)->fastcore.basics.AttrDict:The ideas added, removed, moved and changed in the walk of talk t since the talk was made.
talk_state gives the parts of a talk that “Make it again” changes. Its history row keeps them all, so one Undo (with_state) gives back the talk exactly. A row of any other change keeps only the slides.
with_state
def with_state(
t:dict, before
)->dict:Talk t with before: a list of slides, or a talk_state.
talk_state
def talk_state(
t:dict
)->dict:The slides of talk t, what it keeps of its walk, and the change that the owner asked for.
_groups cuts the slides into the part before the first idea, one group for each idea (its slide, then the slides that follow it), the closing slides (the questions and the recap at the end), and the slides that an earlier “Make it again” moved to the end. A second slide of the same idea (a copy) follows the first. A slide that you put back in the talk (own) follows the slide before it, as a pause does.
_kept gives the slide of an idea that is still in the walk. When the step changed, the slide takes the new slide f, except the parts that you changed. A slide that comes back from “Not in the walk any more” takes the section of its step. A merge that does not pass check_talk keeps the old slide. The new marks keep fm, the hash of the step as the new slide was made from it. So when the walk changed the step again during the model calls, the change still counts in walk_changes. When the slide stays as it is, its marks stay too.
again_slides puts it together: the head, then the walk in its order, then the closing slides, then the slides whose idea left the walk. fresh has a new slide for each idea that needs one (a new idea, or a step that changed). fresh gives (slide, fm) for each idea. New slides get new ids. A parked slide keeps its old section in was, so an idea that comes back into the walk brings back all its slides (a pause, a questions slide), each with its section, in its place.
again_slides
def again_slides(
t:dict, j:dict, fresh:dict
)->dict:The talk_state of talk t made again from walk j, with the new slides fresh (by concept).
put_back puts a parked slide back in the talk: before the closing slides, with the section of its step (or none). It is then your slide (own): a later “Make it again” leaves it where it is.
put_back
def put_back(
t:dict, j:dict | None, sid:str
)->list:The slides of talk t with the parked slide sid back in the talk; j is its walk, or None. A slide that is not parked raises KeyError.
talk_again makes the new slides first, outside the lock: the model writes them (_idea, then fill_slides). Then, under edit_lock, it reads the talk and the walk again and saves one history row by the tutor, with the whole talk_state before it. When the walk changed during the model calls, a new idea that has no slide yet gets one with no model call (its words question, no points), and “Fill the slides” can fill it later. A step that changed again during the calls keeps the slide made from its older state, and the hash of that state, so walk_changes still counts it.
talk_again
def talk_again(
lr:abhyasa.learner.Learning, ask, tid:str, sources:NoneType=None, choice:bool | None=None,
change:str | None=None
)->fastcore.basics.AttrDict:Make talk tid again from its walk, with the same id, and keep your edits. A new change (what the owner asks for) writes each slide again, and the talk keeps it; None keeps the change of the talk. The change is one history row, so one Undo takes it back.
talk_fresh is “Make it again from scratch”: it makes the slides again from the walk with walk_slides, as a new talk would have them, and drops your edits to the slides. The talk keeps its id, its title, its slot and its runs. The model calls run first, outside the lock. Then stop (when given) can end the job before the save. Under edit_lock, it saves one history row by the tutor with the whole talk_state before it, so one Undo or Restore gives back your edits. A talk that was deleted during the calls does not come back.
talk_fresh

lr:abhyasa.learner.Learning, ask, tid:str, sources:NoneType=None, choice:bool | None=None, stop:NoneType=None,

What the room sees
The room sees a public deck. It is made from a list of allowed fields, never by removing fields, so a new field in a talk does not reach the room. It has no notes, no answers, no source of a question, no demo and no path. A figure comes by the sha256 of its bytes.
Only png, jpeg, gif and webp files can be figures. image_type finds the type from the first bytes of the file, not from its name.
image_type
def image_type(
b:bytes
)->str | None:The image type of the bytes b, or None when they are not a png, jpeg, gif or webp image.
The first bytes give the type. A text file with an image name is not an image.
assert image_type(b'\x89PNG\r\n\x1a\n') == 'image/png' and image_type(b'\xff\xd8\xff\xe0') == 'image/jpeg' and image_type(b'GIF89a..') == 'image/gif'
assert image_type(b'RIFF\x00\x00\x00\x00WEBPVP8 ') == 'image/webp' and image_type(b'<svg/>') is None and image_type(None) is NoneThe host gives a resolver that turns an image id into a file. asset_resolver gives the file only when it is inside the assets folder of the vault, exists, and has an image suffix.

)->Callable[[str], pathlib.Path | None]:A resolver from an image id asset:<path> to a file in the assets folder of lr, or None.
_figure reads one figure through the resolver. A figure that the resolver does not find, that is too large, or that is not an image gives None. A resolver that raises gives None too.
A slide shows its passage when it has the beat passage, or when it has no beats. Its points show in the same way, with the beat body.
public_deck gives the title, the public slides and the images by hash. Each slide has exactly the fields id, kind, title, section, passage, body, figure, ask and src. A next slide also has its link. A parked slide is not in the deck. A slide shows its body (its points) on the same terms as its passage. src is the source line of the passage for the room: its label, title and place, with no link. It is None when the room sees no passage.
The run log
Each time the presenter gives the talk, a run log keeps what happened: the place, the time on each slide, the rounds of each question, the hands, the questions from the room that the presenter kept, and the primers that were opened beside a slide. It keeps counts only. It keeps no device token, no address and no answer of one person.
new_run starts a run on the first idea slide. key is a random 64-bit value. The channel name of the two windows has it, so an old window never drives a new run.
new_run
def new_run(
t:dict, now:float=None
)->dict:A new run log of talk t, on its first idea or poll slide.
log_go moves the place. It gives the time since the last move to the last slide that was shown. A new slide gets a new entry. The presenter can go back, so one slide can have more than one entry. end_run closes the last entry and ends the run.
log_go
def log_go(
run:dict, slide:str, beat:int, now:float
):Move the place of run to beat beat of slide.
A question has one or two rounds. counts has one count for each option of a choice, and [right, not right] for an order. A words round has no counts. For hands, there are no rounds: log_main keeps the option that most hands chose. A board or a timeline gives a list: the cards that the room chose, or the order.
log_output
def log_output(
run:dict, slide:str, text:str
):Keep the output of the run for the question of slide: plain text, at most 2000 characters.
log_main
def log_main(
run:dict, slide:str, kind:str, main:int | list
):Keep main, the option that most hands chose for the question of slide, or a list (the cards of a board, the order of a timeline).
log_round
def log_round(
run:dict, slide:str, kind:str, counts:list, n:int, **extra
)->dict:Add a round of the question of slide, with n answers. A third round raises ValueError.
log_question keeps a question from the room, with the note of the presenter. log_beside keeps a primer that was open beside a slide, with the question that the room was asked on its idea (ask), the option that most hands chose (main), and the rounds of phones (rounds, only when there are some).
log_beside
def log_beside(
run:dict, slug:str, slide:str, at:float, secs:float, ask:dict | None=None, main:NoneType=None,
rounds:list | None=None
):Keep the primer slug that was open beside slide for secs seconds, with the question ask on its idea and the room’s answers.
log_question
def log_question(
run:dict, text:str, at:float, shown:bool=False, note:str=''
)->dict:Add a question from the room to run; its id is q1, q2 …
A run is a document of kind talk-run. runs gives the runs of one talk, the newest first.
Learning.runs
def runs(
tid:str
)->fastcore.foundation.L:The runs of talk tid, the newest first.
Learning.put_run
def put_run(
r:dict
)->fastcore.basics.AttrDict:Save run r, and replace an earlier one with the same id.
After the talk
share_right gives the share of right answers in one round, or None for a question with no answer and for a round with no answers. A vote is split when the share is from talks.split_lo to talks.split_hi. Then the room talks in pairs and votes again.
is_split
def is_split(
ask:dict, round:dict, lo:float=None, hi:float=None
)->bool:True when the share right of round is from lo to hi (defaults talks.split_lo and talks.split_hi).
weak gives the slides where the room was unsure: the last round has a share right below below (default talks.weak), or most hands chose a wrong option. top_wrong is the wrong option that most people chose. For hands it is the option that most hands chose.
weak
def weak(
t:dict, run:dict, below:float=None, names:dict=None
)->list:The slides of talk t where the room of run was unsure, in slide order. After each slide come the primers beside it whose question the room was unsure on, as “Softmax (beside idea 3)”, with beside = the slug. names gives the name of each slug.
recap gives the data of the page “After the talk”: the unsure slides, each shown slide with its time and share, the questions from the room, the primers opened beside a slide, and the ideas for a follow-up walk.
recap
def recap(
t:dict, run:dict, names:dict=None
)->fastcore.basics.AttrDict:The data of the recap of run of talk t; names gives the name of the idea of each primer.
The recap file is one HTML file for the room. It needs no server: the style is inline, with the token names of the themes and the light values of Paper, and the figures are data: URLs. It has no script, no speaker notes and no names. All text goes through html.escape, so text from the room stays text.
_ask_html draws one question: the options with the right one marked, the share right of each round, the hands, and the words answers that the presenter showed.
recap_html gives the file. A slide that a run showed and that is parked now is left out: the title and the date, then each shown slide with its title, passage, figure, question and result, and the question of each primer beside it, then the questions from the room that the presenter kept, with the notes, and at the end the sources. The slides come from the public deck, so the file can not show more than the room saw, apart from the right answers.
recap_html
def recap_html(
t:dict, run:dict, resolve
)->str:The recap of run of talk t as one HTML file, with the figures inline.
The handout
You send the handout to the room after the talk, as a PDF. handout_html writes one HTML file, and you save it as a PDF with Print in your browser.
Each slide with content is on its own page: an idea, a primer, a poll and the next slide. A pause, Questions and What we covered have no content, so the handout leaves them out. A question shows no answer on its page. The notebook and the sources come after the slides. The last section is “Answers”, so a reader can try each question first.
A link in the handout can be a shared link, for example a OneDrive link. t['links'] keeps each shared link by its local path. shared_link picks the link of a path: the link of the file, else the link of the nearest folder above it, else the web link, else the file:// link. A OneDrive link does not show the path of a file, so a file in a shared folder gets the folder link. link_rows gives the rows of the Links panel in the talk editor. clean_link accepts only an http or https link.
handout_html
def handout_html(
t:dict, run:dict | None, resolve, chips:tuple=(), names:dict | None=None
)->str:The handout of talk t as one HTML file to print as a PDF. Each slide on stage with content (HANDOUT_KINDS) is on its own page, with its passage and points as markdown (md_part), and its question with no answer. A section line that is the title does not show again. Then the notebook and the sources of chips, with the shared links of t['links'] (row_link); names gives the name of a row by its key. Then “Answers”, with the right answer of each question. With run, a poll gives the count of each option, and a run question gives its output.
md_part
def md_part(
s:str, inline:bool=False
)->str:Safe HTML for the markdown s: headings, lists, tables, links and code blocks, with no script. inline gives one paragraph with no p tag.
row_name
def row_name(
key:str, kind:str, names:dict | None=None
)->str:The name of the row (key, kind) of link_rows: its name in names, else the link with no https://, the name after the chip kind, or the file name.
row_link
def row_link(
links:dict | None, key:str, kind:str
)->str:The link of the row (key, kind) of link_rows in a handout: its shared link in links, else the link of a web row, ’’ for a page of your vault, or shared_link for a local path.
link_rows
def link_rows(
t:dict, chips:tuple=()
)->list:The rows of the Links panel of talk t, as (key, kind): its notebook, then each source chip of chips in order, then the folder of each file. Each key comes one time. kind is notebook, file, folder (a local source, by its full path), web (a GitHub repo or a link, by its link), vault (a page of your vault, by its chip id) or parent (the folder of a file, which takes a link for the files in it but is not a source).
clean_link
def clean_link(
u:str
)->str:The shared link u with no spaces at its ends, or ’’ for no link. A link that is not http or https, or that has a space or a control mark, raises ValueError.
A file link wins over the link of its folder. A file in the folder, or in a folder below it, gets the folder link. A path with no shared link keeps the web link, else its file:// link. clean_link refuses a link that is not http or https.

The walk gets the title of the paper later (repair_paper_titles), but its steps, its talks, the sources of their slides and the sources of its concepts kept the id. repair_id_titles gives each of these the title of the paper, from the walk that reads it. The order of the lists stays, because a repair is not a change that you made.

The builder makes a walk or a talk from a conversation (blocks/build). It keeps a brief: what the owner told it, in a form that the builders use. The brief has the sources, each with a role (main, extra or dropped), the owner’s rules, research on or off, the aim, the audience, no_code, the minutes of a talk, and the slides or steps to keep. This section has the brief and the store of the conversations. The agent and its tools are in the block.

brief_asks puts the brief in plain words for the planner and the slide writer. They get it as an instruction from the owner (owner_says), never as a <source>.
brief_asks
def brief_asks(
b:dict, slides:bool=False
)->str:What brief b asks of the planner and the slide writer: the roles of the sources, the rules, the aim and research off. ’’ when it asks nothing. With slides, for the writer of one slide: a rule about the shape of the whole talk (a poll, the first or last slide, the minutes) is left out, so it does not turn into a point on each slide.
shape_free
def shape_free(

shape_split
def shape_split(

shape_free keeps what one slide writer needs: a sentence about the poll or the last slide goes, and the rest stays. shape_split gives both parts, so the builder can move a shape rule from the aim to the rules.

fit_walk makes the hidden walk of a talk fit a slot of minutes, before the slides are written. It counts each step as its slide does (slide_minutes, with a question, and shown_step for a section of a notebook) and the closing slides, then skips steps from the end until the talk fits. The first step stays, so a talk always has one idea. A talk made again (talk_again) leaves the skipped steps out too.
