Agent tools

Generated from the agent operation catalogue (packages/cli/src/agent-tools.ts) by pnpm run docs. The same 106 operations are MCP tools (elabora mcp <course>) and shell calls (elabora tools call <tool> <course> --args '<json>'); Working with an agent says how to choose. Read tools change nothing in the course; every write is journaled and undoable and returns the diagnostics it caused.

Reading

elabora_overview

Markdown map of the course: plan objectives, sections, screens with their blocks (ids, types, plan references), events; plus the validation summary. Start here. audience “client” gives the review version.

Argument	Type	Required	Description
audience	“agent” | “client”		Default “agent”.
screen	string		Only this screen.

elabora_agent_guide

How to work on a course in this host: MCP/CLI/file choices, complete authoring, translation, design, narration, delivery and review workflows, tool names and human decisions. Read when starting or when unsure which operation to use. The CLI equivalent is elabora tools guide –json (no course needed). Only call tools this connection actually exposes.

elabora_docs

Elabora’s documentation as Markdown. No page: the map (each page’s id and what it covers). page: a page by its id (design, components, free-object-contract, spec, delivery-scorm12, architecture/media…) or a decision by its number (D29); the bundled skills too, for a host that does not show MCP resources (page skills lists them); a long page comes as its opening and its sections, then ask for one with section (its words or its #anchor), or for all of it with full. Read the page a tool, a diagnostic’s fix or the course rules name before designing, extending or explaining a behaviour. search: words to find (« what persists from one screen to the next », « backdrop safe area »): the sections that hold them, to read next. The CLI equivalent is elabora docs [page] [–section <s>] [–search <words>] (no course needed).

Argument	Type	Required	Description
page	string		A page id from the map (design, spec, architecture/media), a decision (D29) or a skill (skills/<name>, skills/<name>/<reference>).
section	string		One section of the page: its heading’s words (Steps) or its anchor (#steps).
full	boolean		The whole page even when it is long.
search	string		Words to find in every page, decision and skill: the sections that hold them all, with the page and anchor to read.

elabora_sources

The author’s sources: the files the module is made from (a client’s brief, a deck, recorded interviews), in sources/, never published. Each with its kind and its readable version: ready, partial (a transcript to come), stale or missing (elabora_source_read writes it), failed (it says why), native (an image, a text, a PDF: read the file itself) or unsupported (an older Office format, .doc .rtf .odt .ppt .odp .key, whose notes say to save it as .docx or .pptx, or as a PDF; other files). Readable versions are made on this computer and nothing leaves it; sources are never published. A client’s brief may hold personal data: quote only what the module needs.

elabora_source_read

A source’s readable version, as Markdown: a Word document’s headings, paragraphs, lists and tables with its comments ({>>…<<}) and tracked changes ({++…++}, {–…–}); a PowerPoint deck slide by slide in reading order, with the speaker’s notes, comments and the pictures each slide places (the slides themselves are not drawn: a PDF of the deck shows them); a video or a recording’s transcript with times, heard on this computer (the model downloaded once, 671 MB) and a video’s frames. Written first when missing or out of date (a long recording takes a while). Long texts come in parts: call again with offset. images: the pictures it names (slides, frames) in the answer, 8 at most; else read them by their paths. An image or a PDF is read as it is: its path. Readable versions are made on this computer and nothing leaves it; sources are never published. A client’s brief may hold personal data: quote only what the module needs.

Argument	Type	Required	Description
file	string	yes	The source: its name under sources/ (brief.docx), sources/brief.docx or its path.
offset	integer		Where to start in the text (characters), for a text longer than 60000 characters.
images	boolean		Send the pictures the readable version names (8 at most) with the text.
refresh	boolean		false: read what is there without writing it again.

elabora_get_plan

The plan (the contract layer, plan.json: the working copy): objectives, ordered items, validated texts (lockedTexts; verbatim: kept « à l’identique », which you never change), validated questions, sources; and its versions (V1, V2…: frozen copies the author made, sent and had validated), with how many changes the working copy has since the validated version and since the latest one. You write the plan with elabora_write_plan; making and validating versions is the author’s.

elabora_plan_diff

What changed in the plan, element by element and matched by plan ids: items, objectives, texts, questions and sources added, removed, moved (from which position) or changed (each field, texts word by word), an item’s part changed. By default since the validated version (what the client will read as changes) to the working copy; from: “latest” for what is in no version yet. Each change has a key (item:ITEM-3) and verbatim: true for a text kept « à l’identique ».

Argument	Type	Required	Description
from	string		V2, validated (default), latest or current.
to	string		V3 or current (default).

elabora_get_screen

Full JSON of one screen (blocks, layers, events).

Argument	Type	Required	Description
id	string	yes

elabora_find_text

Where words occur in what learners read (course.json and the screens, not the plan’s validated texts): each match with its translation unit id, file, JSON pointer, screen, block and number of occurrences. In Markdown, a link’s address, maths and code are not searched.

Argument	Type	Required	Description
query	string	yes
caseSensitive	boolean		Default false.

elabora_translation_table

A language of the course as a bilingual table: every text a learner (or the approver of the translated plan) reads, as a translation unit with its source, its translation and what it asks for: to-translate, to-review (a translation kept from a previous source, or not confirmed), stale (the source changed since: previousSource), translated; problem: what breaks the text (lost maths, links, code or placeholders, too long); anchors: a narration line’s word anchors, as markers in its source and target, and the words of the translation each is placed on (null: to place). screen: only the texts that screen shows (the plan’s validated texts and questions its blocks show included, with the block and field that show each). editor: true marks words only authors read (what the charter’s styles and variants are for, its components’ names and settings, a free object’s settings): translate them so the course reads in its language in the editor too; they hold nothing back. todo: only what asks for something. A language the course does not have yet lists every text to translate; elabora_translate_text starts it.

Argument	Type	Required	Description
language	string	yes	A BCP 47 tag: en, de, pt-BR.
screen	string
todo	boolean		Default false.

elabora_translation_status

Translation readiness for one language, or all existing translations: counts and ids of missing, stale and removed units, broken text or schema constraints, word anchors to place, and translated-plan approval. ready means the texts are present, current, valid and anchored; editor counts apart the words only authors read (the charter’s), which hold nothing back; course validation and human plan approval are separate. Use elabora_translation_table with todo to work on what remains, elabora_look with language to see it, then elabora_build with language to generate its package without changing servers or editing a generated copy.

Argument	Type	Required	Description
language	string		A BCP 47 tag: en, de, pt-BR.

elabora_list_components

Every block type usable in this course: built-in blocks and the course components (components/<id>/), with purpose, category, level (block or screen layout), behaviour, parent of forks, slots, styles and uses. Blocks come before free objects.

elabora_get_schema

JSON Schema of the props of a block type (built-in like “quiz” or a course component id), or of a file/element: “screen”, “event”, “course”, “plan”, “component”, “object-manifest”, “object-tests”. Read it before writing that element.

Argument	Type	Required	Description
name	string	yes

elabora_get_component

A component (built-in or course): manifest, template, stylesheet, effective props schema, slots, styles, fallback, behaviour hooks it must provide, lineage, instances and pending migrations. Read it before forking or editing one. To change its CSS, template or props: elabora_write_component_file (a built-in: elabora_fork_component first).

Argument	Type	Required	Description
id	string	yes

elabora_validate

Run every check (format, plan conformity, pedagogy, accessibility, events, free objects, suspend_data budget against LMS profiles). Returns diagnostics with stable codes, location (file + JSON pointer) and a fix. Warnings the author ignored in the editor (course.json ignored, for example a word a voice almost swallows as a native speaker would) are left out and counted in summary.ignored: leave them alone; includeIgnored lists them, marked ignored.

Argument	Type	Required	Description
profiles	string[]		LMS profile ids (elabora_list_profiles). Default: course.json delivery.lms, else [“unknown”]: no LMS chosen, the strictest values, and package limits only warn.
release	boolean		Client delivery: the plan needs a validated version.
includeInfo	boolean
includeIgnored	boolean
language	string		Check this translation, regenerated from the source; omit for the source language.
allowMissing	boolean		With language: check a draft with missing/stale texts kept in the source language and unplaced anchors at line starts.

elabora_get_object

A free object: manifest, tests, notes and code.

Argument	Type	Required	Description
id	string	yes

elabora_object_map

What to read before changing a free object, in a few thousand characters: each code file’s sections (« // ── Name ── » comments) with their lines and the functions in them, the props (type, choices, default), the words, objects, state, events and the names of the tests. Then read only the lines a change needs.

Argument	Type	Required	Description
id	string	yes
tests	boolean		Each test’s steps in short, one line each.

elabora_list_profiles

Executable LMS profiles (SuccessFactors, Workday, Cornerstone, Docebo, Moodle, Totara, 360Learning, Rise Up, SCORM Cloud, Teach Up, unknown) with their documented constraints.

elabora_list_fonts

The vetted free fonts shipped with Elabora (available offline): family, category and style, what each is good for, weights, italic, subsets, size, licence (SIL OFL), the tokens elabora_add_font sets by default and fonts it pairs with. Files hold the latin subset (Western European languages) and, except UnifrakturMaguntia, the latin-ext subset (Central European, Baltic, Romanian, Turkish…): subsets lists the languages of each. Pick from it first; any other font can still be embedded with its licence (elabora_add_font from or files).

Argument	Type	Required	Description
category	“serif” | “sans-serif” | “monospace” | “display” | “handwriting”

elabora_look

See a screen while designing, in well under a second: a look server kept warm for the course (one browser, no build; started by the first look, stopped after 15 minutes without one) renders it from the files as they are, as learners will see it, with the player’s header and footer and its free objects (3D included). Objects an edit did not touch keep running. Look after every visual change; keep elabora_check_fit, elabora_preview_screenshot, elabora_test_object and elabora_test_package as the final checks. Says whether a slide fits at this size, how long a page is, and where every block is. To inspect: scroll (the window at a position, or a sheet down the page), block (a close-up, scale 2), act (drive a free object from inside its frame, or choose in a dialogue), with what moves and what cannot finish. Also gives a page that follows the looks and the files, to open in a browser pane (in-app browsers included: its free objects show there).

Argument	Type	Required	Description
screen	string		Default: the screen of the last look, else the first screen.
width	integer		Default 1600.
height	integer		Default 900.
state	“initial” | “answered”		Default “initial”.
step	integer		Reveal the steps of the screen up to this one (default: all).
layer	string		Open this layer of the screen (the window is captured). A layer with its own timeline (a narration or timed blocks, D62) shows its end, or the moment at says on its timeline; sheet gives its marks.
at	string		A timed screen at a moment (the window is captured, with the bar): “l2” (a line starts, its caption shown), “l2:end”, “l2:imprimante” (a word of it), “l2:imprimante+0.3s”, “1.5s@2” (seconds into step 2, screens without narration), “step2:end”, or “12.5” (seconds on the timeline).
sheet	boolean		A contact sheet of a timed screen: one capture per mark of its timeline (its start, each block that comes or goes, each cue, each step’s end), captioned with the anchor and what happens: review a narrated slide as a storyboard.
language	string		A translation of the course (default: its language).
viewport	boolean		Only the window (default: the whole page).
motion	boolean		Animations on (default: reduced motion, transitions settled).
select	string		A CSS selector: the computed styles of the elements it matches (five at most) and their parent’s layout, for what a template or the theme draws outside the blocks (a title, a number, an ornament).
controls	boolean		List every control of the screen’s free objects with its box in the window (those covered by the page, a click on their middle not reaching them, are always said).
scroll	string[]		The window scrolled to a position, animations on: px (“1800”), a percentage of the page (“100%”), or a block’s id (the block in view). Several positions (or sheet on a screen without a timeline, default 0/25/50/75/100%): a contact sheet down the page, to see scroll-driven animations build up.
block	string		A close-up of this block (cropped to its box with a small margin; PNG by default up to 2 megapixels, else JPEG), scrolled into view unless scroll says where. With scroll, block or motion the note says what moves: visible/clipped/outside, the animations and transitions of each block in the window (or of this block), their timeline (time, scroll, view) and progress, and the scroll-driven ones that CANNOT FINISH because the page ends before their range.
scale	1 | 2		The close-up drawn at twice its size (2) to read fine detail.
act	string[]		Drive the free object of block from inside its frame, in order, before the capture: “click:<text>” (a button, link, text or label named so), “click:role=<role>[name=<name>]”, “key:<key>” (Enter, ArrowRight, a), “drag:x,y->x,y” (0 to 1 across the object). The note gives the object’s state and the events it emitted; a missing target names what the frame offers. Explore with it; keep an interaction worth keeping in object.tests.json (elabora_test_object). On a dialogue block: “choose:<option>”, one per decision met (retries included, as elabora_dialogue_play), shows its thread at rest after those choices, its end in the window (the notes, the next options or the debrief); the note gives the node waiting, the ending and the score.
type	“jpeg” | “png”		Image format (default: JPEG; PNG for a close-up up to 2 megapixels).

elabora_check_fit

Measure every screen with all its steps in a real browser at the fit sizes of the course (presentation.fit: reference 1600×900, minimum 1280×720 by default) and say which slides scroll, by how many px, which blocks end below the fold, and what moves once the activities are answered (layout shift), plus text too faint against what is behind it; on a phone (375×812), the contrast down the page and the player’s bars that go onto two lines (W_PLAYER_BAR_WRAPS). In scroll presentation (pages of any length) nothing has to fit: it gives the length of each page and the contrast of its text, down the whole page. A screen unchanged since its last measure (its files, the theme, components, objects, Elabora, the browser) is not measured again: its fit comes back with reused (its date); fresh measures every screen again. About a second per slide and a few seconds per scroll page measured; after a change, pass screens: the ones it touched.

Argument	Type	Required	Description
screens	string[]		Only these screens (default: every screen).
fresh	boolean		Measure again the screens unchanged since their last measure.
reference	string
minimum	string
phone	string		The phone size (default 375x812 when reference and minimum are not given), or none.

allowMissing	boolean		With language: check the draft, leaving missing/stale texts in the source language.

elabora_preview_screenshot

Render one screen (or one of its layers) in a real browser once images and free objects are ready, and return a PNG with console errors. Check every designed screen at the reference size (1600×900), at 1280×720 and at 375 px wide: text follows the size classes (1rem is 16, 14 and 15 px). state “answered” shows every activity with its tallest feedback. at: a filmstrip of the animations (contact sheet of frames at these times). scroll: a filmstrip down the page (scroll presentation: scroll-driven animations and objects that follow the scroll), at px or percentages of the page.

Argument	Type	Required	Description
language	string		A BCP 47 tag: en, de, pt-BR.
allowMissing	boolean		With language: capture the draft, leaving missing/stale texts in the source language.
screen	string
width	integer		Default 1600.
height	integer		Default 900.
layer	string		Open this layer of the screen before the capture. A layer with its own timeline (D62) shows its end, and at names moments of its timeline.
step	integer		Reveal the steps of the screen up to this one (default: all).
state	“initial” | “answered”		Default “initial”.
at	one of several[]		Filmstrip: frames at these times in ms, animations on; or, on a narrated screen, as each of these lines starts (“l2”) or ends (“l2:end”), its caption shown.
scroll	string[]		Filmstrip down the page: the window scrolled to each position, in px (“1800”) or a percentage of the page (“40%”), animations on.
motion	boolean		Animations on (default: reduced motion, transitions settled).

elabora_replay_object

Replay one behaviour test of a free object (object.tests.json) inside the built course: on the page that places it, scrolled into view, in real time, with the course around it. Returns a contact sheet of its snapshot steps and the end, and the expectations that failed. To see how the object looks and behaves where learners meet it; the gates stay elabora_test_object. The backdrop’s decoration replays behind the course with its bars, from screen (default: the first one); a set-context step goes to the screen it names.

Argument	Type	Required	Description
id	string	yes
test	string		A test whose name contains this text (default: the first one).
block	string		The free-object block to use when several place the object.
screen	string		For the backdrop’s decoration: the screen it starts behind.
width	integer		Default 1600.
height	integer		Default 900.

elabora_history

Recent changes grouped by batch, oldest first. A batch is one piece of AI work (labelled with the request that started it, when the app marked it) or one human change: its authors, change ids and sequence numbers, files, and whether it is undone. Undo a change or a batch with elabora_undo.

Argument	Type	Required	Description
limit	integer		Number of batches (default 20).

elabora_media_status

Media jobs of the course (imports, optimisations, renditions: queued, running with progress, done, failed) and the media files of assets/ that are not masters yet (W_MEDIA_NOT_OPTIMIZED).

elabora_timeline

A timed screen’s timeline as text, read without a capture: its steps (segments) and their times, each narration line with its speaker, start, end and audio (ok, missing, stale: what to generate or record again), the blocks each step shows, the timed blocks with their moments (the anchor, its time, the effect) and the events its cues fire (timeline.reached, timeline.ended); then each layer that has its own timeline (a narration or timed blocks, D62), read the same way. Times come from the lines’ audio and their word times, estimated from the text while a line has none. Without screen: every narrated screen with the audio of its lines. To see a moment, elabora_look with at: “l2”, “l2:imprimante” or a time in seconds.

Argument	Type	Required	Description
screen	string		A narrated screen (default: the list of narrated screens).
language	string		A language of the course or of one of its translations (default: the course language).

elabora_dialogue_show

A dialogue block as a script, to reread what was written: each node with its lines (speaker, stage direction, line, cues), its options with quality, points, effects and where each goes (« then … »), their reply and feedback, then the endings. text is stable (it also serves diffs); script holds the same as data.

Argument	Type	Required	Description
block	string	yes	A dialogue block (its id).

elabora_dialogue_play

« Jouer un chemin » without a preview: the path of these choices (option ids, one for each decision met, a retried option and the next one included) as the player plays it: its lines and notes, the ending, the score (0-100), points, the decisions and the duration (the lines’ audio, else estimated). ok false when a choice is not offered (offered lists those that were). Check the best path and each mistake after writing a dialogue.

Argument	Type	Required	Description
block	string	yes	A dialogue block (its id).
choose	string[]		Option ids in order (default: none, the dialogue up to its first decision).

elabora_dialogue_paths

Every path of a dialogue block: how many, best and worst score and points, endings reached and never reached, nodes never reached, and each path with its choices, ending, score and duration (2000 at most; complete false past it). Run it after writing or changing a dialogue: an ending or node never reached, or a best score under 100, says what to fix.

Argument	Type	Required	Description
block	string	yes	A dialogue block (its id).
limit	integer		Paths at most (default 2000).

elabora_voice_list

The voices a narration line can be generated with: id (what course.json speakers[].voices[<lang>].voice names), name, gender, register and pace, the licence of the recording it was made from, and whether its model is on this computer (installed) or the size downloaded on first use.

Argument	Type	Required	Description
language	string		Only the voices speaking this language.

elabora_downloads

Argument	Type	Required	Description
screen	string	yes
line	string	yes
language	string		A language of the course or of one of its translations (default: the course language).

elabora_voice_search

Each has its id, name, language (its accent: any voice speaks every language of Eleven v4), gender, accent, age, use case, a preview URL to hear it free, rate (2: twice the credits), quality (high: a professional clone that passed ElevenLabs’ quality check; professional, premade, designed, instant, iconic) and models: by model, the languages ElevenLabs checked the voice speaks well with it, or “failed” when its training for that model failed; a model not named was not trained for it (it still speaks, less like the voice and less expressive). Prefer voices whose models.eleven_v4 (the default model) includes the course’s language. Propose two or three to the author with their previews; set the chosen one with elabora_voice_set { provider: “elevenlabs”, name }. Free: it spends no credits.

page	integer

elabora_voice_estimate

What elabora_voice_generate would make and cost, spending nothing: per line its voice, characters and credits (about, and at most: the list price), the lines a local voice makes free, those given back an earlier take, and the runs said as one exchange (dialogue); in total, the share of the author’s monthly ElevenLabs quota (percent) and whether that needs their approval (needsApproval: from 1 %). Speak to the author in shares of their quota, never in credits; under 1 % generate without asking.

Argument	Type	Required	Description

Search the library first; then Openverse; then make one (elabora_sound_generate). Choose sounds that say something of the scene (the phone that rings, the alarm of a drill), one or two a screen at most, never under an explanation.

elabora_review_list

The online reviews of this course on Elabora’s hosting (those of the publications built from it, in the author’s space): id, title, state (open: reviewers comment; read-only; closed), the versions sent to it (v1, v2…; the latest is what reviewers see first), open and resolved threads, reviewers, and rev (the change number). Read their comments with elabora_review_comments. Needs the author signed in (elabora account login, from a terminal). Creating, sharing or closing a review is the author’s: tell them the command (elabora publish –private, elabora review create) rather than doing it.

elabora_review_comments

Fix open threads; do not resolve them or answer for the author (elabora review resolve / reply are theirs): tell the author what you changed, thread by thread (#number). rev: pass it as since next time to get only what changed.

Argument	Type	Required	Description
review	string		One review (elabora_review_list). Default: the course’s reviews still open or read-only.

Move a screen to another position or section.

Argument	Type	Required	Description
id	string	yes
section	string
after	string
position	integer

elabora_duplicate_screen

Copy a screen after it in its section: its blocks, layers and events get new ids (those named after the screen follow the copy’s id), and the copy’s events point at its own blocks and layers. The copy keeps the original’s title unless given one.

Argument	Type	Required	Description
id	string	yes
newId	string		The copy’s id (default: <id>-copy).

elabora_add_block

Add a block {id, type, props} (built-in type or course component) to a screen, one of its layers, or the slots of a component instance (parent + block.slot). Read elabora_get_schema(<type>) first.

id	string		Id of the copy (default <id>-copy).
screen	string
layer	string
parent	string
after	string

elabora_detach_block

Replace a component instance by its fallback: native blocks with the same content (plan links kept), then the blocks of its slots. The first block keeps the id (a fork of quiz becomes a quiz, learner state kept).

Argument	Type	Required	Description
block	string	yes

elabora_convert_block

Change the form of content without rewriting it (« Transformer en… », D63): a block becomes another presentation of its type, or another type that holds the same content (panels ↔ steps ↔ interactive picture ↔ gallery, panels → a sort in pairs, steps → a sort in order or a process or milestones chart, statement ↔ callout ↔ text, image ↔ gallery of one, a text’s bulleted list → panels or steps), in place, in one undoable change. Its id and its items’ ids are kept, so visited marks and translations follow; the result says what is kept, lost and added (starts empty), and whether learners who started lose their progress in the block. Without to, or with dryRun, nothing is written: the possible targets and those refused with their reason. Prefer it to removing a block and writing another one. language: fr or en for the sentences (default en).

Argument	Type	Required	Description
block	string	yes
to	object		The type to convert into, and its presentation.
dryRun	boolean
language	“en” | “fr”

elabora_set_continuity

Continuity between screens (D65): a block carries on from a block of another screen instead of appearing again (a free object keeps running and moves to its new settings, update(props, transition); another block glides from where its counterpart was). with: the block it carries on from (they share a key: that block’s, else this one’s, else a new one; same type, free objects the same object; blocks of screens, not layers); with null: it no longer carries on from the screens before it (it still does to the screens after it). duration: the passage to it in ms (0 to 3000; null: 700). One undoable change.

Argument	Type	Required	Description
block	string	yes
with	string | null		The block of another screen it carries on from; null cuts it from the screens before it.
duration	integer | null

elabora_upsert_layer

Create or replace a layer (an overlay opened by a show-layer action) on a screen. Without an id it is a new layer with a free one (<screen>-layer), and its blocks without ids get free ones.

Argument	Type	Required	Description
screen	string	yes
layer	object	yes

elabora_remove_layer

Remove a layer from a screen, with its blocks. Events that still show or close it are reported by validation.

Argument	Type	Required	Description
screen	string	yes
id	string	yes

elabora_upsert_event

Create or replace an event (trigger → conditions → actions) on a screen. Read elabora_get_schema(“event”). do may be empty (an event an author started in the app): it does nothing until it has an action, and validation warns (W_EVENT_NO_ACTION).

Argument	Type	Required	Description
screen	string	yes
event	object	yes

elabora_remove_event

Remove an event from a screen.

Argument	Type	Required	Description
screen	string	yes
id	string	yes

elabora_upsert_variable

Create or replace a course variable {id, type, default, …}. String variables need maxLength.

Argument	Type	Required	Description
variable	object	yes

elabora_rename_variable

Give a course variable another name, in one undoable change: the events that read or write it follow, and elabora.lock.json keeps its key, so learners in progress keep its value.

Argument	Type	Required	Description
from	string	yes
to	string	yes	The new name, unused.

elabora_remove_variable

Remove a course variable. Refused while an event reads or writes it: change those events first.

Argument	Type	Required	Description
id	string	yes

elabora_replace_text

Replace words everywhere learners read them (course.json and the screens), in one undoable change. Never the plan’s validated texts (they are the plan’s: elabora_write_plan), never a link’s address, maths or code; a free object’s string keeps its placeholders and its length (else it is skipped and said). units: only these matches of elabora_find_text.

Argument	Type	Required	Description
find	string	yes
replace	string	yes
caseSensitive	boolean		Default false.
units	string[]

elabora_translate_text

Translate texts of the course into a language, in one undoable change (translations/<lang>.xlf; a language the course does not have yet starts here): texts, a list of { unit, target } with the unit ids of elabora_translation_table; target null or empty clears a translation. Keep the source’s Markdown, maths, links, code and ICU placeholders, and stay under maxLength: a translation that breaks them is refused, with the whole call. A stale unit translated again takes the current source. state: translated (default; people review it in the app), reviewed or final (for a person’s own review). Check elabora_translation_status, then elabora_build with language for its package. A narration line whose words time blocks or events (word anchors) shows them in its source as markers, <mrk id=“w-imprimante”>imprimante</mrk>: put each marker around the words of the translation that say the same thing (<mrk id=“w-imprimante”>printer</mrk>), so the translated course anchors there and its voice gives them their times; or name the words in anchors: [{ id, word }]. A marker id the source does not have is refused; one left out is an anchor to place (elabora_translation_status), at the start of its line in a draft.

Argument	Type	Required	Description
language	string	yes	A BCP 47 tag: en, de, pt-BR.
texts	object[]	yes
state	“translated” | “reviewed” | “final”		Default “translated”.

Only when the author asked for it or agreed, after you told them what the warning says and why it may not apply (a quoted maxim whose negation is the author’s, a dense screen that is a primary text to read): never to silence a finding yourself. It stays ignored until what it found changes (the text, the take), then comes back. Errors are never ignored; a client’s exception to a pedagogical rule is a plan waiver, which the author decides with the client. Undo with elabora_undo.

Argument	Type	Required	Description
code	string	yes
key	string	yes
ignored	boolean		Default true.

elabora_rename

Give a section, screen, layer, block or event another id, in one undoable change: every reference follows (sections, events, translation units, stylesheet selectors), a screen file takes the new name, and elabora.lock.json keeps the element’s key, so learners in progress keep their progress. Refused when the new id is used or not a slug. Waivers of the plan that name the id follow too (waivers: how many).

from	string	yes	The id to rename.
to	string	yes	The new id, unused in the course.

elabora_source_add

Copies files the author gave into sources/ (a file already there is not copied again; a name taken is numbered), then writes their readable versions: read them with elabora_source_read.

A client’s brief may hold personal data: quote only what the module needs.

Argument	Type	Required	Description
files	string[]	yes	Absolute paths of files or folders.

elabora_media_import

Import media files (absolute paths: a generated or downloaded image, a recording, a video) into assets/. Each becomes a web master: MP4 H.264/AAC, M4A or WebP (SVG as is), downscaled to the high preset, metadata such as GPS positions removed; the original is not copied. Returns the path under assets/ to put in asset props (without “assets/”). Waits for the conversion unless wait is false; elabora_media_status follows jobs.

Argument	Type	Required	Description
files	string[]	yes	Absolute paths of the files to import.
to	string		Folder under assets/, with or without the prefix (“images/maps” is assets/images/maps; default by kind: assets/video, assets/audio, assets/images).
name	string		File name without extension (one file only; default: the original name, made portable).

Give the file (an absolute path: a transcription tool’s output) or its text. Captions say what is heard, in the language of the course; the transcript (a prop of the block) says what is said and shown.

Argument	Type	Required	Description
block	string	yes	The video block.
file	string		Absolute path of a .vtt or .srt file (or give text).
text	string		The captions themselves, WebVTT or SubRip (or give file).

A new narration line made from a recording, in one undoable change: its text what the recording says (transcribed, or text when you know it), its audio the recording (converted to M4A, its silence at both ends trimmed, provider “recording”), its words timed when the word aligner is installed. It goes after the line after (null: first; default: last), in the step and with the speaker of the line before it unless step or speaker say otherwise. The text is the transcriber’s (punctuated, numbers mostly in words, proper names as heard): read it, and correct the line (elabora_update_screen on narration.lines, or text here) when the author’s spelling differs. Never write the audio files by hand; a recording for an existing line enters with elabora_import_narration.

approvedPercent	number		ElevenLabs only: the share of their monthly quota, in percent, the author agreed to spend after you told them the estimate’s percent. Only needed from 1 % (a minute of audio is far under it on most plans); never set it without asking.

elabora_narration_text_from_audio

A recorded line whose recording says something else than its text (the actor changed words, the script was rewritten after the recording): the line’s text becomes what the recording says, in one undoable change; the recording stays, up to date, its words timed again; anchors follow their words (those whose words are gone are listed as lost), and the line’s translations become « changed since ». preview: only what the recording says beside the text now, written nowhere (show both to the author when the change is theirs to decide). text: the text checked, to write instead of transcribing again. Refused for a line said by a generated voice (it says its text). The text is the transcriber’s (punctuated, numbers mostly in words, proper names as heard): read it, and correct the line (elabora_update_screen on narration.lines, or text here) when the author’s spelling differs.

elabora_transcribe

What a recording says, as text with its words and their times, written nowhere: file is an absolute path (any audio ffmpeg reads). On this computer by default (Parakeet, 25 European languages, punctuation and capitals). To make a line of it, elabora_narration_line_from_audio; to give a line’s recording its text, elabora_narration_text_from_audio. The text is the transcriber’s (punctuated, numbers mostly in words, proper names as heard): read it, and correct the line (elabora_update_screen on narration.lines, or text here) when the author’s spelling differs.

elabora_align_narration

When each word of the voiced lines is said (forced alignment, run on this computer): their words and times are written into the lines’ sidecars, one undoable change per line, and word anchors ({ “line”: “l2”, “word”: “imprimante” }) take their real times instead of times estimated from the text (I_TIMELINE_WORDS_ESTIMATED). screen: one screen (default: every narrated screen); lines: some of its lines; force: lines already timed too. The first use of a language downloads its word aligner once (fr 355 MB, en 95 MB); afterwards lines generated or imported are timed at once. doubtful lists words the voice may have swallowed (a low score): listen to the line and make another take (elabora_voice_generate with lines).

lines	string[]		Line ids of the screen (narration.lines[].id).
language	string		A language of the course or of one of its translations (default: the course language).
force	boolean		Time lines already timed by the same aligner again.

elabora_set_timing

When a block comes (in) and goes (out) on its screen’s timeline, with an effect, in one undoable change: the blocks of a narrated screen appear as the voice names them, anchored to a line or a word of the narration (the anchor holds when the voice is generated again or translated); a screen without narration times them in seconds. Without in a block shows with its step, without out it stays until the end. A timed block keeps its place while it is not there (nothing moves). The contents of a stack (type stack) follow one another: give each its in. Read the result’s diagnostics (E_TIMELINE_ANCHOR_MISSING, W_TEXT_TOO_FAST, E_ACTIVITY_LEAVES_UNANSWERED…), then elabora_timeline and elabora_look at the anchor.

Argument	Type	Required	Description
block	string	yes
in	object | null		A moment and its effect: { “at”: <anchor>, “effect”: “rise”, “duration”: 0.5, “direction”: “left” }. Anchors: { “line”: “l2” } (the line starts), { “line”: “l2”, “edge”: “end” }, { “line”: “l2”, “word”: “imprimante” } (the voice says that word; a few words work too; occurrence: 2 for its second time; offset: 0.3 seconds after, negative before); on a screen without narration { “seconds”: 1.5 } from the start of the block’s step ({ “seconds”: 1.5, “step”: 2 }); { “step”: 2 } or { “step”: 2, “edge”: “end” }. Effects: none, fade (default), rise, slide, zoom, wipe, draw, or the theme’s (course.json theme.effects). Fields set to null go back to their default; the whole moment null removes it.
out	object | null		A moment and its effect: { “at”: <anchor>, “effect”: “rise”, “duration”: 0.5, “direction”: “left” }. Anchors: { “line”: “l2” } (the line starts), { “line”: “l2”, “edge”: “end” }, { “line”: “l2”, “word”: “imprimante” } (the voice says that word; a few words work too; occurrence: 2 for its second time; offset: 0.3 seconds after, negative before); on a screen without narration { “seconds”: 1.5 } from the start of the block’s step ({ “seconds”: 1.5, “step”: 2 }); { “step”: 2 } or { “step”: 2, “edge”: “end” }. Effects: none, fade (default), rise, slide, zoom, wipe, draw, or the theme’s (course.json theme.effects). Fields set to null go back to their default; the whole moment null removes it.

elabora_set_dialogue_node

Write one node of a dialogue block whole, in one undoable change: a new node (after: a node id, first: at the start; default: at the end), or the node with the same id replaced in place (moved with after or first). A node: { “id”, “title”?, “lines”: [{ “id”, “speaker”?, “text”, “expression”?, “cues”? }], “prompt”?, “options”: [{ “id”, “text”, “label”?, “quality”, “reply”?, “feedback”?, “points”?, “next”?, “retry”?, … }], “next”?, “end”? } (elabora_get_schema dialogue).

Argument	Type	Required	Description
block	string	yes	A dialogue block (its id).
node	string	yes	The node’s id.

elabora_voice_set

The voice of a speaker (course.json speakers[]) in a language: speakers[].voices[<lang>] = { provider, voice, name, settings }, its settings kept unless given. Lines of that speaker made with another voice become out of date (W_NARRATION_AUDIO_STALE): elabora_voice_generate makes them again. One undoable change. An ElevenLabs voice (elabora_voice_search): provider “elevenlabs”, its name, and settings { model (eleven_v4 by default, the one that plays stage directions), stability, similarity (0 to 1; lower stability: more expressive) }. Choosing a voice costs nothing.

Argument	Type	Required	Description
speaker	string	yes
voice	string	yes	A voice id from elabora_voice_list or elabora_voice_search.
language	string		A language of the course or of one of its translations (default: the course language).

elabora_voice_generate

Generates the narration lines of a screen with their speaker’s voice (course.json speakers[].voices[<lang>]): by default the lines whose audio is missing or out of date (W_NARRATION_AUDIO_MISSING, W_NARRATION_AUDIO_STALE); lines: those; all: every line. Each generation is a new take, written to assets/narration/<lang>/<screen>/<line>.m4a with its sidecar (generated voice, take, credit for the module credits): one undoable change per line. The text said is the line’s, after the pronunciations of the line and of the course (course.json pronunciations { “<lang>”: [{ text, say }] }: add one when a word is said wrong, then generate again). voice: set that voice for the speaker of the lines first. take: put back an earlier take of one line (elabora_voice_takes). Local voices are free: the first use of a language downloads its model once (fr 354 MB, en 126 MB); a line takes a few seconds. ElevenLabs voices spend the author’s monthly quota, which Elabora always says as a share of it, never in credits: under 1 % of the quota (a line is about 0.07 % of a Starter plan; a screen of a few lines is under it, a long script is not: elabora_voice_estimate says) generate without asking. From 1 % the call spends nothing and returns needsApproval with the estimate: tell the author « ~N % of your monthly ElevenLabs quota » (estimate.percent), ASK them, and only with their agreement call again with approvedPercent: N. A generation stops by itself if the service charges far more than allowed (overBudget). A line out of date gets back an earlier take of the same text, voice and delivery at no cost. dialogue: lines of several ElevenLabs speakers that follow each other in a step are said as one exchange (turns, interruptions written with « — »), then cut into lines, the pauses between them taken from it. Stage directions in square brackets in a line ([chuchote], [rit], [un temps]) are played by Eleven v4 and never shown nor counted as words.

Argument	Type	Required	Description
screen	string	yes
lines	string[]		Line ids (narration.lines[].id). Default: those missing or out of date.
all	boolean		Every line of the screen, a new take each.
voice	string		Set this voice (elabora_voice_list) for the speaker of the lines first.
language	string		A language of the course or of one of its translations (default: the course language).
take	integer		Put back this take of one line (with lines: [id]).
dialogue	boolean		Say runs of a step’s lines by several ElevenLabs speakers as one exchange (the whole run again).
approvedPercent	number		The share of their monthly quota, in percent, the author agreed to spend after you told them the estimate’s percent. Only needed from 1 %; never set it without asking.

elabora_voice_install

Downloads the model of a language’s local voices once for this computer (fr 354 MB, en 126 MB; checked, resumable). elabora_voice_generate does it on first use too: call this first when a long call would time out. force: removes it first and downloads it again (a reinstall, refused as elabora_download_uninstall is).

Argument	Type	Required	Description
language	string	yes
force	boolean

Adds a sound to the course: from, a library id (elabora_sound_search), openverse:<id>, or a file on this computer (then license is required: CC0-1.0, CC-BY-4.0…, own for a sound the author made or bought). Copied into assets/sounds/<id> with its sidecar (source, author, licence, changes); trim keeps a part, fade fades its end; a lossy file kept whole is not encoded again. Then use it: a sound line { “id”, “sound”, “caption”? } in a narration’s lines (elabora_update_screen) or a dialogue’s node lines, an action { “type”: “play-sound”, “sound”, “volume”? (up to 2), “loop”?, “fade”?, “fadeOut”?, “start”?, “end”? (a part of the file, seconds), “duck”? (dB the music and ambiences go down under it, never a voice), “caption”? } in an event, a cue of a dialogue’s line or a dialogue option, or a background track in course.json sounds.background [{ “sound”, “from”, “to”?, “volume”?, “start”?, “end”? }] (elabora_update_course; enable « Affichage » so learners can switch music off). Undo with elabora_undo.

Argument	Type	Required	Description
from	string	yes
id	string
trim	object		The part kept, in seconds.
fade	number		Seconds of fade out at its end.
loop	boolean		Made to loop (an ambience).
caption	string		Its caption in the course’s language (« Le téléphone sonne. »), kept as a suggestion in its sidecar: write it where the sound is used when it carries meaning no text gives; leave it out for a decorative sound or when the text around says it.
license	string
author	string
title	string
url	string

elabora_sound_generate

Makes a sound effect with ElevenLabs (the author’s key) from a description in English (« a desk phone rings twice, close, office room tone »), 0.5 to 30 s (duration; without it the service chooses), loop for an ambience, and adds it to the course like elabora_sound_add (its sidecar says it was generated: « IA et crédits » says so). Its cost is a share of the author’s monthly quota, never said in credits: a sound of 3 s is about 0.4 % of a Starter plan, 10 s about 1.3 %. Under 1 % it runs; from 1 % the call spends nothing and returns needsApproval with the estimate: tell the author « ~N % of your monthly ElevenLabs quota », ASK them, and only with their agreement call again with approvedPercent: N. estimate: only say the share. The same request is never paid twice. Search the library and Openverse first: a generated sound costs, and every try costs as much as the one kept.

Argument	Type	Required	Description
prompt	string	yes
duration	number
loop	boolean
influence	number		How closely it follows the description (default 0.3).
id	string
caption	string		Its caption in the course’s language (« Le téléphone sonne. »), kept as a suggestion in its sidecar: write it where the sound is used when it carries meaning no text gives; leave it out for a decorative sound or when the text around says it.
estimate	boolean
approvedPercent	number		The share of their monthly quota, in percent, the author agreed to spend. Only needed from 1 %; never set it without asking.

elabora_download_install

Downloads one now (checked, resumable): the tools that need it do it on first use too; call this first when a long call would time out. force: removes it first and downloads it again (a reinstall, refused as elabora_download_uninstall is).

Argument	Type	Required	Description
id	string	yes	An id from elabora_downloads: voices-fr, aligner-en…
force	boolean

elabora_download_uninstall

Removes one from this computer to free its space: only when the author asks. Refused (E_VOICE_IN_USE, E_ALIGN_IN_USE) while it is in use (lines said, words placed) or being downloaded, in any process. What modules already contain stays; the next use downloads it again.

Argument	Type	Required	Description
id	string	yes	An id from elabora_downloads: voices-fr, aligner-en…

elabora_create_object

Scaffold a free object (objects/<id>/: manifest, code, tests, notes) serving given plan objectives. Only when no native block can do the job. decoration: a decoration of the course backdrop instead (theme.backdrop.object; no objectives): a 2D canvas that follows the course (ctx.context with the screen’s rank, its section’s, the direction), keeps out of the player’s bars and lands at once when frames are still.

Argument	Type	Required	Description
id	string	yes
title	string	yes
objectives	string[]
items	string[]
decoration	boolean

elabora_write_object_file

Write one file of a free object: object.manifest.json, object.js, object.tests.json or object.notes.md. Then run elabora_test_object.

Argument	Type	Required	Description
object	string	yes
file	“object.manifest.json” | “object.js” | “object.tests.json” | “object.notes.md”	yes
content	string	yes

elabora_test_object

Run the automated gates of a free object in a browser: smoke, behaviour tests, budgets, visual snapshots, accessibility. Tens of seconds; an object unchanged since its last full run on this computer (its folder, the theme tokens and fonts, the language, the Elabora code, the browser) is not run again: its result comes back at once with reused (force runs it). A full run is recorded in object.gates.json for the proof dossier. updateSnapshots also removes the baselines of states no test names any more, and lists those kept for other browsers and systems.

Argument	Type	Required	Description
id	string	yes
updateSnapshots	boolean		Accept new visual baselines (only when the visual change is intended).
only	string		Run only the behaviour tests whose name contains this text (not recorded).
force	boolean		Run the gates even when nothing changed since the last run.

elabora_write_plan

Write the plan (plan.json, the working copy) at any time: the whole plan (plan) or a JSON Patch (RFC 6902) of it. Checked against the plan’s schema before anything is written, refused with why. Before its first validation, draft it whole from what the author gave you (sources, objectives, the client’s brief): the items grouped by part (items[].part), each objective with a short name of three to five words (objectives[].short), decided and question (D51). Once a version was validated, write the changes all the same and tell the author what you changed: the app marks them, and the author makes the next version and sends it. Refused when it would change a text kept « à l’identique » (lockedTexts[].verbatim): ask the author. Rewording a validated text is writing it here: every block with its textRef follows. Items moved (a move, a part changed) take the screens that cover them along in the same change (moved says which).

Argument	Type	Required	Description
plan	object		The whole plan.json (id, title, objectives, items…).
patch	object[]		A JSON Patch of the plan as it is.

elabora_set_plan_voiceover

The voice-over of a plan item (a storyboard’s voice-over column), line by line, written in the plan. A screen that covers the item then takes it as its narration script (elabora narration from-plan). lines: [{ speaker, text }], speaker a course.json speaker id (default: the first); null removes the voice-over. It is translated with the plan, and not kept word for word in the module (the script can be reworded).

Argument	Type	Required	Description
item	string	yes	A plan item id (ITEM-3).
lines	array | null	yes

elabora_export_plan_document

Write the plan’s document, what the client reads, comments and signs, to dist/<course>-plan.<format>: docx (Word, for clients who comment in Word: its headings, a bookmark per objective, item, text and question named after its id, the changes since the validated version as tracked changes, the author’s notes as comments), pdf (the « Bon pour production » to attach to a purchase order; needs a Chromium: Elabora’s or Google Chrome) or html (one page to read or print). It shows the latest version of the plan (version: V2, or current for the working copy; the working copy when there is no version) and records that it was sent; it never makes a version. For when the author asks to send the plan: when the plan changed since the latest version, say so to the author, who makes the next one first or sends this one. The document says the version’s state and never who wrote it.

Argument	Type	Required	Description
format	“docx” | “pdf” | “html”	yes	docx, pdf or html.
version	string		V2, or current (the working copy). Default: the latest version.

elabora_dialogue_export

Write a dialogue block for the client to dist/<course>-<block>.<to>: its map (every node and ending, placed by Elabora), then its script (who says what, each option with its quality, where it goes and its note), in the course’s language; html (one page) or pdf (needs a Chromium: Elabora’s or Google Chrome). For when the author asks to send a dialogue for validation; the client also plays it in the Revue.

Argument	Type	Required	Description
block	string	yes	A dialogue block (its id).
to	“html” | “pdf”	yes	html or pdf.

elabora_build

Validate and compile the SCORM 1.2 package and its proof dossier into dist/. Waits for media jobs under way. mediaQuality (default: course.json delivery.mediaQuality, else high) ships renditions of the media below high, to fit LMS size limits (E_PACKAGE_TOO_LARGE gives the size at each quality). target “web”: a module for a plain web server instead, without LMS (a folder to serve and its ZIP, dist/<course>-<version>-web), with the settings of web; profiles are refused there.

Argument	Type	Required	Description
language	string		Build/test this translation from the source course; outputs go into the source course dist/. Omit for the source language.
allowMissing	boolean		With language: explicitly make a draft; missing/stale texts stay in the source language and unplaced word anchors move to line starts.
profiles	string[]		LMS profile ids (elabora_list_profiles). Default: course.json delivery.lms, else [“unknown”]: no LMS chosen, the strictest values, and package limits only warn.
release	boolean
mediaQuality	“high” | “medium” | “low”
target	“scorm12” | “web”		scorm12 (default): a package for LMSs. web: a module for a plain web server.
web	object		Settings of the web target (target “web” only). A publication: the defaults. A showcase: { progress: “none”, navigation: “free” }. A review link: { review: { origins: [“https://revue.elabora.studio”] } }.
languages	“all”		all: one package of every language (D59): the course’s own and each translation that is ready and approved, which learners switch in place (the player’s language item). Not with language.

elabora_test_package

Build, then run the package in the LMS emulator for the given profiles (launch topologies, close and resume, status, accessibility). Slow.

Argument	Type	Required	Description
language	string		Build/test this translation from the source course; outputs go into the source course dist/. Omit for the source language.
allowMissing	boolean		With language: explicitly make a draft; missing/stale texts stay in the source language and unplaced word anchors move to line starts.
profiles	string[]		LMS profile ids (elabora_list_profiles). Default: course.json delivery.lms, else [“unknown”]: no LMS chosen, the strictest values, and package limits only warn.
modes	“iframe” | “popup” | “popup-chain” | “nested-iframe” | “new-tab”[]

elabora_write_design_file

Write a design file: theme/<name>.css (course stylesheet) or generators/<name>.mjs (asset generator). Design is free; content stays in blocks. Read the design layer first (elabora_docs design; skill elabora-visual-design).

Argument	Type	Required	Description
file	string	yes
content	string	yes

elabora_upgrade_theme

Put the theme’s rules under the components (course.json theme.cascade components-over-theme, docs D32) without changing how the course looks: a course without theme.cascade (I_THEME_CASCADE_OLD) still has its theme after the component stylesheets, so a general theme rule (.t-figure img { width: 100% }) silently overrides a component’s own rule. The theme’s declarations of properties the components also set go into a top-level @layer overrides { … } block of the theme stylesheet (which stays over the components); the rest become the course’s defaults, under them. Then move out of that block the rules that are course-wide defaults, and look again (elabora_look, elabora_check_fit name what the theme still overrides: W_STYLE_COMPONENT_OVERRIDDEN). One change; elabora_undo reverts it.

elabora_player

The learner’s player (D58): read it, or change it in one undoable change. Two bars, top and bottom, each an ordered list of items: logo, title, progress (one segment per part when the course has two sections or more: each fills as its screens are completed, the part shown is marked, a click goes to the part’s first screen; options.progress.parts false makes it one bar in one piece, not clickable, and options.progress.percent false hides its percentage; where the learner is is the player’s to say, never an eyebrow over the titles), spacer (« Espace flexible »: one per bar, always on; the items before it go to the start of the line, those after it to the end, and the narration controls stretch before it does), outline (the drop-down table of contents; options.outline.label: its button reads « Sommaire », the part shown or the screen shown), controls (the narration’s play, seek bar, captions, volume, transcript, speeds), resources, glossary, credits (« IA et crédits »: an « IA » mark when the module has generated voices or media), display (« Affichage »: text size, larger captions, shortcuts; off in a new module), language (« Langue »: the learner switches between the package’s languages, D59; off in a new module, shows only in a package built with –languages all and more than one language), previous, next, exit (Quit, SCORM only). An item shows when it is enabled and has something to show (resources, glossary entries, an AI mention or credits, a logo file); a bar with nothing to show is removed. Without changes, returns the bars (each item enabled or not, whether it shows and why not, its options), the items in neither bar, what the course has (its languages in the package too), how learners move through it (navigation.mode, lockUntilComplete), every player token with its value (player.top.background, player.top.text, player.bottom.background, player.bottom.text, player.accent, player.onAccent, player.progress, player.tooltip.background, player.tooltip.text, player.radius, player.density) and the findings about the player. To make the player fit a module’s theme: set the bar colours from the charter (a light top bar with the text colour for airy themes, the primary colour for a strong identity), player.accent for Next and Play, player.radius to the theme’s corners (999: pills), a logo (options.logo.asset, an image of assets/; options.logo.plate puts it on a light plate when it does not read on the bar, W_PLAYER_LOGO_CONTRAST), and keep the defaults otherwise; the contrast of every pair is checked. Never hand-write CSS for the bars when a token says it. Changes: enable, disable, move ({ item, bar, index }; the spacer moves within the bar named), options ({ logo: { asset, alt, plate }, outline: { label: outline | section | screen }, progress: { parts, percent }, glossary: { linkTerms }, controls: { seekBar, captionsByDefault, volume, transcript, speeds: none | 0.75-1.5 | 0.75-2 } }; null resets an option), position ({ top, bottom }: window or page), tokens (player.* only; null removes), reset (the bars of a new course), resources ([{ id, title, description, asset }] for files of assets/ (PDFs and images open in the player), [{ id, title, description, url }] for https:// links, opened in a new tab; addResources: [{ path, title, description }] copies files from outside the course into assets/resources/ and adds them, titled by the PDF’s own title or the file’s name when no title is given), glossary ([{ id, term, definition, variants, translate, source }]; texts link to an entry with [word](glossary:<id>); translate: false keeps a term and its variants as they are in every language; source says where a gathered term was found, { kind: “source”, id: <name in sources/>, at: “p. 4” } or { kind: “screen”, id: <screen> }, for the author: never shown to learners nor translated), credits (lines), linkTerms (« Relier les termes aux écrans »: true for every term, or the ids of some; the first time each term or a variant is in each screen’s texts becomes a link, a screen that already links to it is left as it is; it also runs when glossary.linkTerms is turned on and for the terms the glossary gains while it is on, never otherwise, so a link the author removed stays removed; the result lists the links placed, and per translation the translated texts that took the same link and those left to translate again). Removing an entry from glossary removes its links in the same change, its words kept, in the translations too (result unlinked, translations[].unlinked). Keep speeds at 0.75-2 unless the author insists: learners who go at their own pace stay.

Argument	Type	Required	Description
target	“scorm12” | “web”		Which package the report describes (exit shows in SCORM packages only). Default “scorm12”.
enable	“logo” | “title” | “progress” | “spacer” | “outline” | “controls” | “resources” | “glossary” | “language” | “display” | “credits” | “previous” | “next” | “exit”[]

addResources	object[]		Files copied into assets/resources/ and added to the resources, each in its own undoable change (before the other changes): titled by title, else the PDF’s own title, else the file’s name.
linkTerms	one of several		Link the glossary’s terms to the screens, the first time in each: true for every term, or the ids of some.

elabora_add_font

Embed a font in the course with its licence: copies its WOFF2 files and licence into theme/fonts/<id>/, declares its faces in course.json theme.fonts (the player writes the @font-face rules) and gives its CSS stack to tokens (for: body → font.body, heading → font.heading, any other name → custom token font.<name> such as mono or display, read as var(–t-font-mono); none for no token; default: the font’s usual role). Takes the latin files, and the latin-ext files too when the language of the course or of a translation needs them (Polish, Czech, Romanian, Turkish…: one face per file, with its unicode range, loaded only by pages that use its letters); subsets chooses. family: a vetted font (elabora_list_fonts). Another font: from, the folder or .tgz of its Fontsource package (npm pack @fontsource-variable/<id>), whose other subsets (cyrillic, greek, vietnamese…) subsets can name; or files, local WOFF2 files, with license, their licence file (weights and style are read from the files). Adding a family again replaces its faces (add it again after adding a language). Undo with elabora_undo.

Argument	Type	Required	Description
family	string		A vetted family (“EB Garamond”), or the family name to declare for from/files (default: the font’s own).
weights	integer[]		Static fonts: the weights to take (default: all vetted; 400 and 700 for a Fontsource package). A variable file covers its whole range.
styles	“normal” | “italic”[]		Default: every style there is.
subsets	string[]		The subsets to embed: latin, latin-ext (vetted fonts), or any of a Fontsource package (cyrillic, greek, vietnamese…). Default: latin, and latin-ext when a language of the course needs it.
for	string[]		Tokens that get the font’s stack: body, heading, mono, display… or [“none”].
from	string		Folder or .tgz of a Fontsource package (npm @fontsource/<id>, @fontsource-variable/<id>): its files of the subsets (with their unicode ranges) and LICENSE.
files	string[]		Local WOFF2 (or WOFF) files of one family.
license	string		With files: the licence file of the font (OFL.txt, LICENSE…).
