Under the hood
Editing actions and client features
Shared primitives — editing actions and client features
Everything a client calls to change a workspace or render a user-facing feature: block mutations, pages and journals, backlinks, code-block execution, undo / redo, templates, reminders, and the @outl/shared TS surface every GUI client wraps.
Every entry here routes its mutations through Workspace::apply — the op log stays the source of truth.
Part of the Shared primitives catalog — the index of every part lives in shared-primitives.md.
Before writing any helper, scan these tables first.
Most “I need a small string transform / id helper / md coercion / tree walk” needs already have an owner here —
the cost of finding the existing one is a grep;
the cost of missing it shows up later as drift between two parallel implementations (the user is the one who hits the divergence).
For the reuse-first rule (why this matters, past drift incidents, what to do when a primitive doesn’t exist yet), see Contributing → Reuse-first.
1. Block mutations (outl-actions::block + collapsed + todo + quote)
Every entry here routes through Workspace::apply — never build a LogOp from a client and apply it directly.
| Intent | Use this | File |
|---|---|---|
| Append a single block under a parent | outl_actions::block::append_block | crates/outl-actions/src/block/create.rs |
| Append a tree / forest (with children) under a parent | outl_actions::block::append_tree / append_forest (uses BlockTreeSpec → returns BlockTreeOutcome) | crates/outl-actions/src/block/create.rs |
Create sibling before a block (vim O; floor-slot swap when the anchor is first child) | outl_actions::block::create_before | crates/outl-actions/src/block/create.rs |
| Create sibling after / child under a block | outl_actions::block::create_after / create_under | crates/outl-actions/src/block/create.rs |
| Create sibling after a block, appending at page end when the anchor is stale | outl_actions::block::create_after_or_append (the desktop/mobile create_block stale-anchor fallback — one owner, no per-client duplication) | crates/outl-actions/src/block/create.rs |
| Create sibling before a block, appending at page end when the anchor is stale | outl_actions::block::create_before_or_append (the O / new-block-above counterpart of create_after_or_append — same stale-anchor tolerance so a concurrent sync reload that re-mints the id never surfaces block <id> is not in the tree) | crates/outl-actions/src/block/create.rs |
| Edit a block’s text | outl_actions::block::edit_text | crates/outl-actions/src/block/edit.rs |
| Split a block at a character offset (Enter mid-text): head stays in the block, tail becomes a new sibling right after it, children stay with the head | outl_actions::block::split_block | crates/outl-actions/src/block/split.rs |
Move a block to sit after an arbitrary target (cut-and-paste-block; crosses pages; one Op::Move, preserving id + refs; rejects self-subtree cycles) | outl_actions::block::move_after | crates/outl-actions/src/block/moves.rs |
| Indent / outdent / move up / move down a block | outl_actions::block::indent / outdent / move_up / move_down | crates/outl-actions/src/block/moves.rs |
| Re-parent a block under an arbitrary page/block (cross-page move) | outl_actions::block::move_under | crates/outl-actions/src/block/moves.rs |
Delete a block (Move(node, TRASH_ROOT), never physical) | outl_actions::block::delete | crates/outl-actions/src/block/moves.rs |
Toggle a block’s collapsed flag (converges via Op::SetCollapsed) | outl_actions::collapsed::toggle_block_collapsed / set_block_collapsed | crates/outl-actions/src/collapsed.rs |
Cycle / split / read task state — TODO → DOING → DONE, encoded as a text prefix. TodoState::prefix is the one owner of the marker spelling, and the widths differ (DOING is 6 chars), so measure it instead of assuming | outl_actions::todo::cycle_todo / split_todo / TodoState / TODO_PREFIX / DOING_PREFIX / DONE_PREFIX | crates/outl-actions/src/todo.rs |
| Set TODO/DONE state outright (not “advance one step”) | outl_actions::todo::set_todo | crates/outl-actions/src/todo.rs |
| Toggle TODO/DONE on a block in one call | outl_actions::block::toggle_todo | crates/outl-actions/src/block/edit.rs |
Read / toggle blockquote state (encoded as "> " text prefix, CommonMark-compatible) | outl_actions::quote::is_quote / split_quote / toggle_quote / QUOTE_PREFIX | crates/outl-actions/src/quote.rs |
| Toggle blockquote on a block in one call | outl_actions::block::toggle_quote | crates/outl-actions/src/block/edit.rs |
2. Pages and journals (outl-actions::page + journal)
| Intent | Use this | File |
|---|---|---|
| Page-property keys (constants — don’t hardcode the strings) | outl_actions::page::SLUG_KEY / KIND_KEY / TYPE_KEY / TITLE_KEY | crates/outl-actions/src/page.rs |
Canonical type:: value marking a page as a person (@ mention autocomplete filter) | outl_actions::page::PERSON_TYPE | crates/outl-actions/src/page.rs |
Page metadata (slug, kind, title, page_type) for a node id | outl_actions::page::page_meta / PageMeta / PageKind | crates/outl-actions/src/page.rs |
Validate a slug for filesystem safety (.., /, \, control chars) | outl_actions::page::is_valid_slug | crates/outl-actions/src/page.rs |
Derive a deterministic page/journal-root id from slug (so every creation path — in-app, outl-md reconcile, desync recovery — converges on ONE root; the single owner) | outl_core::NodeId::from_slug (thin wrapper outl_actions::page::page_id_from_slug) | crates/outl-core/src/id.rs |
Find / list / create-if-missing pages (find_by_slug resolves a deterministic winner when a slug has >1 root, so a split-brain workspace stops flickering pre-merge) | outl_actions::page::find_by_slug / list_all / open_or_create | crates/outl-actions/src/page.rs |
Repair a split-brain workspace where a slug has >1 page/journal root (re-parents every child under the canonical root, trashes the emptied duplicates, all via Ops so it converges on every device; idempotent) | outl_actions::merge_duplicate_slug_roots (impl outl_actions::page_merge) | crates/outl-actions/src/page_merge.rs |
Repair journal titles doubled by concurrent offline creation (two devices minted the same deterministic root and each wrote the slug into the root’s Yrs text, so the concurrent inserts concatenated into "2026-06-252026-06-25"; clears the text via Op::Edit so the title falls back to the slug; idempotent, journal-only) | outl_actions::repair_doubled_journal_titles (impl outl_actions::page_repair_titles) | crates/outl-actions/src/page_repair_titles.rs |
Delete a page (move root to NodeId::trash() via one Op::Move; whole subtree travels with it; returns PageMeta so callers can drop projections + navigate away; ActionError::PageNotFound when the slug doesn’t resolve) | outl_actions::page::delete (re-exported as outl_actions::delete_page) | crates/outl-actions/src/page.rs |
Remove a page’s .md + .outl from disk (the inverse of apply_page_md_with_sidecar; idempotent on missing files; pairs with page::delete) | outl_actions::journal::remove_page_projection (re-exported at crate root) | crates/outl-actions/src/journal/paths.rs |
Open-or-create a page from a human-typed name (slugifies + keeps original as title, used when a [[ref]] / #tag / picker query may not be a valid slug) | outl_actions::resolve::open_or_create_by_name | crates/outl-actions/src/resolve.rs |
Open-or-create whatever a user-typed ref target points at (date → journal, else literal/slugified/title match → existing page, else create) — handles @-prefixed mentions by stripping the @ and marking new pages as type:: person; the one decision tree so frontend regex and backend parser cannot drift on [[2026-13-01]] or [[@avelino]] | outl_actions::resolve::open_or_create_by_ref | crates/outl-actions/src/resolve.rs |
Search pages typed type:: person, fuzzy-ranked by query (powers the @ mention autocomplete in every client) | outl_actions::person::search_persons | crates/outl-actions/src/person.rs |
| Read / write a property on a page (or any node) | outl_actions::page::read_text_prop / set_property | crates/outl-actions/src/page.rs |
| Migrate pre-page-model blocks under today’s journal (run on boot) | outl_actions::page::migrate_legacy_into_today | crates/outl-actions/src/page.rs |
| Open / create the journal for a specific date or today | outl_actions::page::open_journal / open_today | crates/outl-actions/src/page.rs |
Journal date labels & day arithmetic (slug ↔ date, title, [[YYYY-MM-DD]] ref, prev/next day) | outl_actions::dates::journal_slug / journal_title / journal_ref / date_from_slug / previous_journal_date / next_journal_date | crates/outl-actions/src/dates.rs |
Today’s journal date in the configured timezone (delegates to clock) | outl_actions::page::today | crates/outl-actions/src/page.rs |
Week arithmetic — ISO-week tag (#2026-W22, %G-correct at year boundaries) and “days until next <weekday>” (same weekday → 7, never 0) | outl_actions::dates::week_tag / days_until_next_weekday | crates/outl-actions/src/dates.rs |
Current date / time in the user’s configured timezone ([calendar] timezone, DST-aware via chrono-tz; OS local when unset). Call init once per client at boot; page::today delegates here, so use now_local / today instead of chrono::Local::now() (issue #107) | outl_actions::clock::init / now_local / today | crates/outl-actions/src/clock.rs |
Parse a human-typed date in any supported spelling (2026-04-22, 2026/04/22, 22/04/2026, Roam’s April 22nd, 2026, Sept 3rd, 2025, 22 April 2026) into a NaiveDate, or into the ISO label outl uses for journal slugs / [[date]] refs — the one owner of the ordinal-stripping logic that used to be copied in four places (paste normalization, outl daily, outl import, Obsidian frontmatter). parse_date_arg layers relative offsets (+3d, -2w, +1m, bare 5d) on top for slash-command / CLI arguments | outl_actions::dates::parse_flexible_date / parse_date_label / parse_date_arg | crates/outl-actions/src/dates.rs |
Parse an outl:// deep link URL into a navigation target (one parser, every GUI client routes the result to its own open_* command — never reparse per client) | outl_actions::parse_deep_link / DeepLinkTarget / DeepLinkError / DEEP_LINK_SCHEME | crates/outl-actions/src/deeplink.rs |
| Filesystem paths for journals / pages / a specific page | outl_actions::journal::journals_dir / pages_dir / page_md_path | crates/outl-actions/src/journal/paths.rs |
Render a page node out to .md | outl_actions::journal::render_page_md | crates/outl-actions/src/journal/render.rs |
Apply an edited .md back into the workspace (with / without sidecar) | outl_actions::journal::apply_page_md / apply_page_md_with_sidecar | crates/outl-actions/src/journal/apply.rs |
Apply an already-rendered .md string back into the workspace + sidecar, skipping a redundant re-render (the GUI commit path renders once for the undo diff and reuses it) | outl_actions::journal::apply_page_md_with_sidecar_rendered | crates/outl-actions/src/journal/apply.rs |
Project a page after a mutation without deleting content the op log never saw — the post-mutation counterpart to _if_stale, which only guards read paths. Every GUI write path routes through it (ProjectionWriter, block move, template instantiate); refusing returns PageMarkdownAheadOfLog and the edit stays safe in the op log | outl_actions::apply_page_md_with_sidecar_guarded | crates/outl-actions/src/journal/apply.rs |
Apply every page’s .md to disk in one pass | outl_actions::journal::apply_all_pages_md | crates/outl-actions/src/journal/apply.rs |
Run a closure that mutates a page’s .md (read → modify → write atomically) | outl_actions::journal::mutate_page_md | crates/outl-actions/src/journal/apply.rs |
Atomic .md write (crash-safe, wraps outl_md::atomic::write_atomic) | outl_actions::journal::write_md_atomic | crates/outl-actions/src/journal/paths.rs |
Decide whether re-projecting a .md would delete content the op log never saw (multiset of content lines, whitespace-insensitive — the owner of that verdict, so the doctor’s read-only listing and --repair cannot disagree). Owned by outl-md (it is also reconcile_md’s producer-side check); re-exported here so every existing outl_actions:: path resolves | outl_actions::content_lines_missing_from (→ outl_md::unlogged::content_lines_missing_from) | crates/outl-md/src/unlogged.rs |
Decide whether the sidecar you are about to pass to the verdict above can answer it at all — false for a pre-0.11 sidecar whose entries all carry text: "". An empty verdict from a reference that cannot answer is not “nothing at risk”, so a caller that skips this reads “I could not check” as permission to write. Same owner, same crate, re-exported for the same reason | outl_actions::sidecar_can_answer (→ outl_md::unlogged::sidecar_can_answer) | crates/outl-md/src/unlogged.rs |
Scan the materialized tree for a block whose current text is a proper prefix of an earlier Op::Edit revision — i.e. a truncating edit and the dropped tail is still reconstructible from the append-only log | outl_actions::scan_truncated_blocks → TruncatedBlock | crates/outl-actions/src/recover.rs |
Write a recovered revision back as a new Op::Edit (never a log rewrite); refuses when the block changed since the scan, so the write stays additive | outl_actions::restore_truncated_block | crates/outl-actions/src/recover.rs |
3. Backlinks (outl-actions::backlinks)
| Intent | Use this | File |
|---|---|---|
Extract [[ref]] tokens out of a block’s text (tolerates unbalanced openers) | outl_actions::backlinks::extract_refs | crates/outl-actions/src/backlinks.rs |
Backlink DTO returned by the queries below (carries ancestors: Vec<BacklinkCrumb> — root-first ancestor chain of the citing block, excluding the page root, empty when the block sits at root level) | outl_actions::backlinks::Backlink | crates/outl-actions/src/backlinks.rs |
One breadcrumb entry in Backlink::ancestors (plain text, TODO/DONE prefix stripped) | outl_actions::BacklinkCrumb | crates/outl-actions/src/backlinks.rs |
Drop a Backlink’s source subtree (children) for the GUI wire — keeps the leaf (text, tokens, todo, properties) + ancestors; GUI rows only ever render source_block.tokens, the TUI keeps the full form since it reads the index in-process | outl_actions::Backlink::into_shallow | crates/outl-actions/src/backlinks.rs |
Walk every backlink for a target / a PageMeta — one-shot convenience: builds a fresh BacklinkIndex and looks it up, fine for a single call (CLI, tests) but pays the O(blocks) build every time | outl_actions::backlinks::backlinks_for_target / backlinks_for_page | crates/outl-actions/src/backlinks.rs |
Pre-computed inverted backlinks index (target key -> referencing blocks) — build once (O(blocks), off the input path / a background thread) then look a page’s backlinks up in O(refs); for_page / for_target / count_for_page (no-clone count) / len / is_empty. A long-lived client (TUI, desktop, mobile) should hold one of these instead of calling backlinks_for_page per navigation | outl_actions::BacklinkIndex | crates/outl-actions/src/backlinks_index.rs |
Build the backlinks index from the .md files on disk — the client-facing builder. Touches no Workspace, holds no lock, Send; use this from every client. Building it from the in-memory workspace instead (Workspace::block_text per block) forces a lazy-boot vault (#179) to materialize entirely and holds the workspace lock across the walk — the “opening the journal / pressing Esc freezes” regression | outl_actions::build_backlink_index_from_disk | crates/outl-actions/src/backlinks_index.rs |
Build the backlinks index from an in-memory Workspace — one-shot wrappers only (backlinks_for_page / backlinks_for_target, CLI/tests with no .md on disk); do not call this from a client’s index-rebuild path, use build_backlink_index_from_disk instead | outl_actions::build_backlink_index | crates/outl-actions/src/backlinks_index.rs |
| Order a backlinks list chronologically (group-stable by source page, newest- or oldest-first; drives the issue-#142 direction toggle on every client) | outl_actions::sort_backlinks | crates/outl-actions/src/backlinks_sort.rs |
4. Code-block execution (outl-actions::exec)
The cross-client glue every UI uses to wire a “run this fence” gesture (TUI g x, desktop Cmd+Shift+X, mobile long-press → “Run code”) through to outl-exec and back.
outl_actions::exec::run_code_block is the only entry point a Tauri command / TUI action should call — never re-implement the flat-DFS walk, the .md path lookup, or the DTO shape per client.
| Intent | Use this | File |
|---|---|---|
Resolve a NodeId to its flat DFS index inside an outline forest (the order outl_exec::run_block_at_index expects) | outl_actions::flat_index_for_block | crates/outl-actions/src/outline.rs |
Orchestrate execution: walk DFS, resolve .md path, call outl_exec::run_block_at_index, build DTO | outl_actions::exec::run_code_block | crates/outl-actions/src/exec.rs |
Serializable mirror of outl_exec::ExecOutput (stdout/stderr/duration_ms/exit) | outl_actions::ExecOutputDto | crates/outl-actions/src/exec.rs |
Outcome shipped to the client (language + result_ok xor error; client adds the refreshed view) | outl_actions::RunCodeBlockOutcome | crates/outl-actions/src/exec.rs |
The runtime catalog (which languages are available) is selected by the binary that consumes this crate, via outl-exec features in its own Cargo.toml.
outl-actions itself depends on outl-exec with default-features = false so it doesn’t drag wasmtime (Rust runtime) into the mobile IPA via the back door.
The query runtime (outl_exec::runtimes::query) is a special case: it returns OutputFormat::Embeds instead of OutputFormat::Text, so the orchestrator renders results as live !((blk-XXXXXX)) embeds rather than a code-fence stdout dump.
It also overrides Runtime::auto_run() to return true, so query blocks always re-run on page load without needing the auto-run:: property or manual gx.
The query engine also exposes a structured API for plugins and code that runs outside the ```query fence:
| Intent | Use this | File |
|---|---|---|
Structured query from a QueryParams object (plugin-facing) | outl_exec::run_query_structured | crates/outl-exec/src/runtimes/query.rs |
| DSL query from a string (user-facing) | outl_exec::run_query_dsl | crates/outl-exec/src/runtimes/query.rs |
| Query parameters struct (status, tag, kind, since, text, sort, limit) | outl_exec::QueryParams | crates/outl-exec/src/runtimes/query.rs |
| Query result hit (handle, text, status, page) | outl_exec::QueryHit | crates/outl-exec/src/runtimes/query.rs |
In JS code blocks, the same API is available as outl.query({ status: "todo", … }).
5. Undo / redo history (outl-actions::history)
Bounded snapshot stacks with vim semantics (a new edit clears redo) shared by GUI clients — the desktop’s Cmd+Z / Cmd+Shift+Z ride these.
Restores route through outl_md::reconcile_md, so an undo is new ops in the log, never a rewrite (invariant #1 holds).
This is not per-keystroke undo inside an uncommitted draft — that belongs to the client’s editor widget.
| Intent | Use this | File |
|---|---|---|
Bounded undo / redo stacks over any snapshot type (record / undo / redo / can_undo / can_redo / clear) | outl_actions::history::HistoryStacks | crates/outl-actions/src/history.rs |
| Default per-stack bound (matches the TUI’s session cap) | outl_actions::DEFAULT_HISTORY_CAP | crates/outl-actions/src/history.rs |
Restore a page to a previously-rendered .md snapshot (write + reconcile → min ops through Workspace::apply) | outl_actions::restore_page_md | crates/outl-actions/src/history.rs |
6. Templates
| Intent | Use this | File |
|---|---|---|
List all template pages (any page with a non-empty template:: property), sorted by name (each entry flags duplicate when another page shares its name) | outl_actions::list_templates → TemplateEntry | crates/outl-actions/src/template/list.rs |
Resolve the page node for a template:: <name> (first in tree order; tracing::warn! on a name collision) | outl_actions::template::list::find_template_by_name | crates/outl-actions/src/template/list.rs |
Instantiate (deep-copy) a structural template’s subtree under a target block, with {{token}} substitution and from-template:: traceability on each root clone | outl_actions::instantiate_template | crates/outl-actions/src/template/instantiate.rs |
Resolve a callable template’s code block (language, source, declared params::) | outl_actions::resolve_call → CallResolution | crates/outl-actions/src/template/call.rs |
Parse a ```call:<name> block’s key: value body into params | outl_actions::parse_call_params | crates/outl-actions/src/template/call.rs |
The template name invoked by a ```call:<name> fence (inverse of the exec path’s fence read; drives the backlinks traceability match) | outl_actions::call_target_name | crates/outl-actions/src/template/call.rs |
Inject a params binding into a callable template’s source (serde_json-escaped, language canonicalized via outl_md::lang::canonical, so quotes/newlines in a value can’t break or inject into the generated program) | outl_actions::inject_call_params | crates/outl-actions/src/template/call.rs |
Detect + parse a ```call:<name> block into (name, params) — the shared “is this a call invocation?” check every client uses before running normal exec | outl_actions::parse_call_invocation | crates/outl-actions/src/template/run.rs |
Execute a callable template (resolve → inject params → run via a client RuntimeRegistry → write the > **result:** subtree). The single owner every client wraps for call: execution | outl_actions::run_callable_block | crates/outl-actions/src/template/run.rs |
| Template property key constant | outl_actions::TEMPLATE_KEY | crates/outl-actions/src/template/mod.rs |
| Traceability property key constant (set on structural-instance root blocks) | outl_actions::FROM_TEMPLATE_KEY | crates/outl-actions/src/template/mod.rs |
| Callable params key constant | outl_actions::PARAMS_KEY | crates/outl-actions/src/template/mod.rs |
Reserved template name for the daily journal body — a page with template:: journal is auto-instantiated (untraced) into every fresh daily note | outl_actions::JOURNAL_TEMPLATE_NAME | crates/outl-actions/src/template/mod.rs |
7. Reminders (remind::)
Block-level notification rules.
The schedule math has exactly one owner — outl_actions::reminders::next_fire_at.
Every surface (TUI overlay, desktop panel, mobile sheet, each OS bridge) calls it; a second opinion in TS or Swift about when a reminder fires is drift that reaches the user before it reaches a test.
User-facing spec: reminders.md.
| Intent | Use this | File |
|---|---|---|
Property key that carries a reminder rule (don’t hardcode "remind") | outl_md::REMIND_KEY | crates/outl-md/src/remind.rs |
Parse a remind:: value into a rule + the warnings it triggered (never fails destructively — an unreadable rule just doesn’t schedule) | outl_md::parse_remind → RemindParse { rule: Option<RemindRule>, warnings } | crates/outl-md/src/remind.rs |
| Pull the rule off a block’s property list | outl_md::rule_from_properties | crates/outl-md/src/remind.rs |
The parsed rule + its parts (RemindAnchor::Now / At, RemindStop::Done / Time / Date) | outl_md::RemindRule / RemindAnchor / RemindStop | crates/outl-md/src/remind.rs |
| Hard caps the parser enforces (1-minute interval floor, 10-fire ceiling) | outl_md::MIN_INTERVAL_MINUTES / outl_md::MAX_FIRES_CAP | crates/outl-md/src/remind.rs |
When does this rule next fire? — pure, clock-free, takes now as a parameter. THE single owner | outl_actions::next_fire_at (+ ReminderState) | crates/outl-actions/src/reminders/schedule.rs |
| Every reminder in the workspace with its next fire resolved (reads pages from disk, consults the workspace only for the snooze table) | outl_actions::scan_reminders → Vec<Reminder> | crates/outl-actions/src/reminders/scan.rs |
| Device-local “already delivered” record the scan takes as input | outl_actions::FiredLog / FiredRecord | crates/outl-actions/src/reminders/scan.rs |
Silence a block’s reminder until an instant (writes Op::SnoozeRemind, so it converges to every device) | outl_actions::snooze / snooze_until | crates/outl-actions/src/reminders/mod.rs |
Local wall clock ↔ epoch ms, resolved through the configured timezone (never chrono::Local directly) | outl_actions::local_naive_to_epoch_ms / epoch_ms_to_local_naive | crates/outl-actions/src/reminders/mod.rs |
| Read a block’s converged snooze instant | outl_core::tree::Tree::snoozed_until / snoozed_ids | crates/outl-core/src/tree/mod.rs |
Every node carrying a given property key, without a tree walk (the transpose of properties_of; O(total properties), materializes no block text) | outl_core::tree::Tree::nodes_with_property | crates/outl-core/src/tree/mod.rs |
Device-local delivery preferences (enabled, quiet hours as (start, end) minutes) | outl_config::RemindersCfg / RemindersCfg::quiet_window | crates/outl-config/src/schema.rs |
Deliver what came due + update the device-local fired log (7-day TTL, <root>/.outl/reminders-fired.json — a dotfile so it never rides the sync surface). In outl-actions because every client delivers, the TUI included; behind the Tauri layer the TUI couldn’t reach it | outl_actions::take_due (+ load_fired_log / save_fired_log / fired_log_path / FIRED_TTL_DAYS) | crates/outl-actions/src/reminders/fired.rs |
| Format “in 3h” / “tomorrow 09:00” and bucket a list Today / Tomorrow / This week / Later / Done (shared by both GUI clients) | @outl/shared formatNextFire / groupReminders | crates/outl-frontend-shared/src/api/commands.ts |
8. Frontend shared primitives (@outl/shared)
The TS + Solid catalog’s canonical home is crates/outl-frontend-shared/CLAUDE.md → “Today’s surface”.
The rows below are the embed / block-ref pieces the desktop wires for issue #147, mirrored here so a grep for the reuse index finds them.
| Intent | Use this | File |
|---|---|---|
Render inline markdown tokens to JSX; the blockref token (((blk)) / !((blk))) resolves to the source block’s text when embeds carries the handle (orphan = raw chip) | <MarkdownInline embeds= … /> (@outl/shared/markdown) | crates/outl-frontend-shared/src/markdown/MarkdownInline.tsx |
Render an embed’s subtree read-only — ↳-nested, max depth 4 (mirrors the TUI’s emit_embedded_children) | <EmbeddedSubtree /> (@outl/shared/markdown) | crates/outl-frontend-shared/src/markdown/EmbeddedSubtree.tsx |
The reply shape of resolveEmbeds ({ handle, text, page_slug, status, children: BlockNode[] }); EmbedMap is Record<string, ResolvedBlock> | ResolvedBlock (@outl/shared/api/types) | crates/outl-frontend-shared/src/api/types.ts |
The handle iff a block is embed-only (a bare !((blk))), so a client knows to render <EmbeddedSubtree /> below it | embedOnlyHandle(tokens) (@outl/shared/outline) | crates/outl-frontend-shared/src/outline/index.ts |
Collect every blockref + embed handle in an outline (DFS) so a client resolves them in one resolveEmbeds round-trip | collectBlockRefHandles(outline) (@outl/shared/outline) | crates/outl-frontend-shared/src/outline/index.ts |
Wire the Tauri webview’s OS file drag-drop to a block-resolved handler; desktop and mobile both consume this so the drop geometry (physical→CSS pixels, data-block-id hit-test) can’t drift | installFileDrop(handlers), physicalToCss, blockIdFromElement / blockIdAtPhysical, joinAssetMarkdowns, appendMarkdownToBlock (@outl/shared/drag-drop) | crates/outl-frontend-shared/src/drag-drop/index.ts |
| Import a dropped file without creating a block, returning the ready-to-insert markdown link for the caller to splice at the drop target | importAssetFile(sourcePath) → Promise<ImportedAsset> (@outl/shared/api/commands) | crates/outl-frontend-shared/src/api/commands.ts; backend import_asset_file wraps outl_actions::import_asset (Asset links) |
