; LaTeX highlights — vendored from nvim-treesitter (Apache-2.0) and reconciled

; onto pmacs' recognized capture set (src/highlight.rs; framing Q#LX2 / F4).
|

;
|

; Reconciliation vs the verbatim upstream (previous commit):
|
||||
; * @spell / @nospell markers stripped — meaningless to pmacs, and a
|
||||
; same-node @nospell risks clobbering the real capture.
|
||||
; * The 8 predicate-gated patterns (#eq? / #any-of? / #lua-match?) removed:
|
||||
; pmacs evaluates only `#is? local` predicates, so unevaluated they would
|
||||
; over-match every generic command (as \if-conditional / emphasis) and
|
||||
; every line_comment (as a magic directive). Re-instating them is deferred
|
||||
; to predicate support. This also drops the only @markup.italic/@markup.strong
|
||||
; uses, so those need no remap.
|
||||
; * Fall-through captures remapped onto the recognized set:
|

; @module -> @keyword (\begin/\end/sectioning commands)
|

; @label -> @type (environment / theorem names)
|

; @markup.heading -> @keyword.control (section-title text)
|
||||
; @markup.link* -> @constant (labels, refs, citations, urls)
|
||||
; @markup.math -> @string (inline/displayed formulas)
|

# LaTeX grammar + math parser — framing (inline-math substrate)
|
||||
|
||||
**Revision 3 — pre-implementation. Ground truth: canonical `main` @
|
||||
`96d0bae`, protocol v19, 2026-07-23. Status: framing only; no
|
||||
implementation.** Rev 1's pmacs-side scouting passed review with every
|
||||
in-repo anchor verified exactly; rev 2 corrected the external crate ground
|
||||
truth (the originally named crate provably cannot link) and refreshed the
|
||||
in-flight-lane snapshot; rev 3 folds in two provenance-wording corrections —
|
||||
the fork-vs-upstream attribution and the now-discharged provenance diff — and
|
||||
relaxes the `Cargo.toml` sequencing note. See §0.1 for the changelog.
|
||||
|
||||
Parent arc: `docs/inline-math-framing.md` — currently an **untracked,
|
||||
desktop-only framing** not yet committed to the repo, so this path will not
|
||||
resolve on a fresh clone; committing it as its own docs PR (or listing it in
|
||||
the handoff's machine-local doc inventory) is a tracked follow-up. That note
|
||||
frames the full four-tier inline-math renderer; its Tier 4 (GPU render) lands on
|
||||
`pmacs-gpu/src/main.rs`, the render path that folding and any future math
|
||||
draw pass also contend for. **This lane deliberately carves out only the
|
||||
frontend-agnostic, conflict-free substrate** — the parts that can land now,
|
||||
in a sibling worktree, without touching a single file the two in-flight
|
||||
efforts will own.
|
||||
|
||||
## 0. Why this lane, why now (parallel-safety)
|
||||
|
||||
Two efforts are in flight; both share files with this lane, and the
|
||||
disjointness must be described against their **current** state, not a stale
|
||||
one (F5, verified 2026-07-23):
|
||||
|
||||
- **folding** (`folding` branch) is at **rev 5, APPROVED, Stage 1
|
||||
implementing** (head `40a820a`, clean worktree) — not framing-only. Its
|
||||
eventual touch set owns `semantic_render.rs`, `src/overlay.rs`,
|
||||
`src/syntax.rs` (the `ParseViewHandle` reads at `:696`/`:706`),
|
||||
`src/daemon.rs` (grid render + `dispatch_key` pre-edit unfold), the Lua
|
||||
command/dispatch layer + `src/lua_bindings/mod.rs`, **both frontends'
|
||||
gutter/render**, and `pmacs-gpu/src/main.rs` (fold mirror).
|
||||
- **gpu-invocation** (`gpu-invocation` branch) is **not framing-only either**:
|
||||
its worktree carries **uncommitted implementation right now, including edits
|
||||
to root `Cargo.toml`** — one of this lane's two shared files. It will own
|
||||
`src/main.rs`, `pmacs-gpu/src/main.rs` (argv/startup),
|
||||
`pmacs-gpu/src/attach.rs`, root `Cargo.toml` (`default-run`), and the README.
|
||||
- **inline-math Tier 4** (deferred, this lane's downstream) would own
|
||||
`pmacs-gpu/src/main.rs` (the render path — the three-way hotspot).
|
||||
|
||||
This lane touches **none** of those code paths. Its entire footprint is: one
|
||||
`BUILTIN_LANGUAGES` append, one `Cargo.toml` dependency line, one new in-repo
|
||||
query overlay file, and one new pure module `src/math_parse.rs`. The only two
|
||||
shared files, with disjointness re-verified:
|
||||
|
||||
- `src/syntax.rs` — a **localized append to the language table at `:1095`**
|
||||
(after the `yaml` entry's `},`, before `];` at `:1096`), disjoint from
|
||||
folding's `ParseViewHandle` reads at `:696`/`:706`.
|
||||
- root `Cargo.toml` — a **dependency line** in the grammar block
|
||||
(`:142`–`:219`). gpu-invocation's live edit is the `default-run` key in
|
||||
`[package]`; **no `default-run` key exists yet**, and the grammar dep block
|
||||
is a different region ~100 lines away. The two edits are **disjoint hunks
|
||||
that git auto-merges cleanly** — the same config-registry ∥ Vterm precedent
|
||||
this section cites — so no ordering is technically required. Flagging the
|
||||
overlap is coordination courtesy, not a merge risk.
|
||||
|
||||
This is the localized-single-region-append pattern that already rebased with
|
||||
**zero conflicts** when config-registry and Vterm Stage 1 shared
|
||||
`editor.rs`/`mod.rs` (`docs/active-work.md`, "Closed since the last
|
||||
snapshot"). Its precondition — agree the file split before either lane starts,
|
||||
keep each lane's footprint in shared files to a localized region — holds here
|
||||
by construction; the now-active `Cargo.toml` overlap is disjoint (above) and
|
||||
needs only coordination courtesy.
|
||||
|
||||
## 0.1 Revision history
|
||||
|
||||
### Round 1 (rev 1 → rev 2)
|
||||
|
||||
- **F1 (severe).** Rev 1's `tree-sitter-latex` 0.1.0 (crates.io) **cannot
|
||||
link.** It is a third-party repackage (publisher `cijiugechu`) of an old
|
||||
latex-lsp grammar snapshot; its declared repo
|
||||
`github.com/tree-sitter/tree-sitter-latex` **does not exist** (404, and the
|
||||
crate's VCS sha is absent from latex-lsp history). The grammar declares
|
||||
external tokens but the tarball **ships no `scanner.c`**, and its `build.rs`
|
||||
compiles the scanner only "if it exists." Proven empirically: an offline
|
||||
path-dep build fails with undefined
|
||||
`tree_sitter_latex_external_scanner_scan`/`_serialize`/`_deserialize`. The
|
||||
rev-1 scouted facts (`LANGUAGE: LanguageFn`, shim ABI compatibility) were
|
||||
each individually true — docs.rs cannot surface a *link* failure, which is
|
||||
why the scout missed it. **Fix: Q#LX1 re-based on a working vehicle (F2).**
|
||||
- **F2 (severe).** A working, verified vehicle exists:
|
||||
**`codebook-tree-sitter-latex` 0.6.1** (26k downloads). See Q#LX1.
|
||||
- **F3 (severe).** Q#LX2's vendoring source did not exist: latex-lsp ships
|
||||
**no `queries/` directory** (its `include = ["queries/*"]` is vestigial),
|
||||
and no first-party LaTeX `highlights.scm` exists anywhere. **Fix: Q#LX2
|
||||
re-pointed at nvim-treesitter's query.**
|
||||
- **F4 (major).** Q#LX2's "real work" is broader than capture renaming — the
|
||||
fall-through classes and predicate-support gap are now named in Q#LX2.
|
||||
- **F5 (major).** §0's in-flight snapshot was stale (folding is rev 5 /
|
||||
approved / implementing; gpu-invocation has live uncommitted `Cargo.toml`
|
||||
edits). §0 rewritten to reality; the disjointness argument survives with one
|
||||
added sequencing obligation.
|
||||
- **F6 (minor).** Parser is **~500 lines** (parent framing, Tier 2 + the
|
||||
integration table), not ~1,000. `LanguageEntry` has **six** fields.
|
||||
`math_parse` sorts **before** `mcp` in `src/lib.rs` (alphabetical). The
|
||||
0.6.1 crate is **~3.1 MB compressed**. All corrected below.
|
||||
|
||||
### Round 2 (rev 2 → rev 3)
|
||||
|
||||
- **R2-1.** Corrected the source attribution: the crate is a republish **from
|
||||
the codebook project's fork** of `latex-lsp/tree-sitter-latex` (the fork
|
||||
modernized the bindings to the `LanguageFn` shim and renamed the crate), not
|
||||
a cut from an upstream `latex-lsp` commit. GitHub serves fork-network objects
|
||||
through the parent repo's API, which made the fork commit `948b89c` look
|
||||
upstream in rev 1/2. §2 fixed.
|
||||
- **R2-2.** The Q#LX1 provenance-diff gate is **discharged, not deferred**: the
|
||||
diff against `latex-lsp` master is byte-identical on `grammar.js`/`scanner.c`
|
||||
(460 node types in both; metadata-only drift in
|
||||
`grammar.json`/`node-types.json`); the sole residual is generated `parser.c`,
|
||||
covered by the parse smokes. §2 and Q#LX1 now record the result instead of
|
||||
the obligation.
|
||||
- **R2-3.** Relaxed §0's `Cargo.toml` note: the dep append and gpu-invocation's
|
||||
`default-run` key are disjoint hunks ~100 lines apart that git auto-merges
|
||||
cleanly (the cited config-registry ∥ Vterm precedent). Kept as coordination
|
||||
courtesy; dropped the inaccurate "can't assume a clean auto-merge" rationale.
|
||||
|
||||
## 1. What ships
|
||||
|
||||
- **Stage 1 — LaTeX/TeX syntax highlighting.** A bundled LaTeX grammar
|
||||
(Q#LX1) plus a vendored highlights overlay (Q#LX2) lights up `.tex` /
|
||||
`.latex` / `.sty` / `.cls` buffers. Self-contained, user-visible, shippable
|
||||
as its own PR. This is the "basic LaTeX mode" foothold and the tier-1
|
||||
detection substrate the inline-math arc needs.
|
||||
- **Stage 2 — math parser: DEFERRED by decision (Q#LX5).** The pure
|
||||
`src/math_parse.rs` recursive-descent parser is framed but **not built in
|
||||
this lane** — the reviewer and author concur it should land beside its
|
||||
Tier 3 layout consumer, not ahead of it. Recorded in §Deferred with its
|
||||
rationale so the decision is not re-litigated.
|
||||
|
||||
Also deferred to the inline-math arc proper (§Deferred): Tier 3 layout,
|
||||
Tier 4 GPU render, and instance-side `(math_environment) @math` injection
|
||||
detection.
|
||||
|
||||
## 2. Ground truth (scouted 2026-07-23, `main` @ `96d0bae`; pmacs-side
|
||||
anchors verified in review, external facts corrected per §0.1)
|
||||
|
||||
### Grammar table
|
||||
|
||||
- **`LanguageEntry` struct — `src/syntax.rs:766-801`**, **six** fields:
|
||||
`name` (`:769`), `extensions: &[&str]` (`:774`),
|
||||
`loader: fn() -> tree_sitter::Language` (`:778`),
|
||||
`highlights_query: &[&str]` (`:789`), `locals_query: &[&str]` (`:793`),
|
||||
`injections_query: &[&str]` (`:800`). There is no `tags`/`filename`/`shebang`
|
||||
field — extensions are the only Rust-side detection signal.
|
||||
- **`BUILTIN_LANGUAGES` table — `src/syntax.rs:816` … `];` at `:1096`.** A new
|
||||
entry appends after the `yaml` entry's `},` at `:1095`. The "adding a
|
||||
grammar" checklist is documented in-place at `:803-815`.
|
||||
- Example entry, verbatim (`src/syntax.rs:985-992`):
|
||||
```rust
|
||||
LanguageEntry {
|
||||
name: "python",
|
||||
extensions: &["py", "pyi"],
|
||||
loader: || tree_sitter_python::LANGUAGE.into(),
|
||||
highlights_query: &[tree_sitter_python::HIGHLIGHTS_QUERY],
|
||||
locals_query: &[],
|
||||
injections_query: &[],
|
||||
},
|
||||
```
|
||||
- Grammar crate deps live in `Cargo.toml:136-219` (`tree-sitter = "0.26"` at
|
||||
`:136`; grammar crates `:142`–`:219`).
|
||||
|
||||
### Detection chain
|
||||
|
||||
- The `extensions` field drives `language_name_for_extension`
|
||||
(`src/syntax.rs:1223`) and `language_name_for_path` (`:1235`).
|
||||
- The full precedence chain (PR #132 modeline work) is Lua,
|
||||
`detect_buffer_language` at `builtin/runtime/syntax.lua:452-466`: **modeline
|
||||
→ grammar extension → LSP filetype map → filename map → shebang.** Because
|
||||
grammar-extension detection sits *ahead* of the LSP filetype map, adding
|
||||
`tex`/`latex`/`sty`/`cls` to the new entry's `extensions` **wires the whole
|
||||
chain with no Lua edit**.
|
||||
|
||||
### Query sourcing
|
||||
|
||||
- **No in-repo `.scm` highlight overlays exist today.** Every grammar sources
|
||||
its queries from crate-exported `&'static str` constants (naming varies:
|
||||
`HIGHLIGHTS_QUERY`, `HIGHLIGHT_QUERY`, `HIGHLIGHT_QUERY_BLOCK`; documented at
|
||||
`src/syntax.rs:779-800`). The CUDA entry (`:919-923`) shows queries composed
|
||||
as a **slice of fragments** in the field.
|
||||
- The only `.scm` in the tree is `audit/audit-rules.scm`, pulled via
|
||||
`include_str!` at `src/audit/mod.rs:76` — the sole precedent for shipping
|
||||
static query text from a repo file.
|
||||
- **Highlight-capture handling** (F4): the prefix-walk at
|
||||
`src/highlight.rs:189` already absorbs `@function.macro`, `@keyword.*`,
|
||||
`@string`, `@comment`, and `@punctuation.*`. But `@markup.*` (headings,
|
||||
italic, bold, math), `@module`, and `@label` **fall through to default
|
||||
style** — i.e. the most LaTeX-distinctive content would paint as plain text
|
||||
unless the vendored query's captures are renamed onto the recognized set.
|
||||
- **Predicate support** (F4): pmacs evaluates only the `#is? local` property
|
||||
predicate; `#match?` / `#eq?` / `#any-of?` / `#lua-match?` are **silently
|
||||
ignored** for every grammar (pre-existing, not a blocker). The nvim query
|
||||
has 8 such uses that must be curated out or accepted as benign over-matching.
|
||||
|
||||
### Injection seam (future math detection)
|
||||
|
||||
- `collect_injection_matches` (`src/syntax.rs:375-427`) is the capture-
|
||||
consumption point: it reads `@injection.content` (`:381`) and
|
||||
`injection.language` (`:385-388`), plus `#set!` properties (`:397-404`).
|
||||
Child-language resolution is `resolve_injected_language` (`:304`). The
|
||||
markdown→rust fenced-code injection is the working precedent. A future
|
||||
`(math_environment) @injection.content` + `#set! injection.language "math"`
|
||||
hooks in here unchanged (Q#LX4, deferred).
|
||||
|
||||
### Module registration & tests
|
||||
|
||||
- Crate modules are declared in the alphabetized `pub mod` block at
|
||||
`src/lib.rs:42-142`; `mod math_parse;` sorts **before** `mcp` (`:100`).
|
||||
- Grammar test convention (CUDA template, `src/syntax.rs:2130-2221`): a table
|
||||
guard `builtin_languages_include_<lang>`, a smoke test
|
||||
`<lang>_grammar_loads_and_parses_*` (`reg.language(...)` → parse → assert
|
||||
root kind + `!has_error()`), a highlight-resolve test, and an extension-
|
||||
resolution test. End-to-end paint template: `src/highlight.rs:1296-1346`.
|
||||
- **Greenfield confirmed** — no `math`/`latex`/`tex` code anywhere in `src/`,
|
||||
`builtin/`, `pmacs-gpu/`, `pmacs-protocol/`.
|
||||
|
||||
### Crate facts (external, corrected + reviewer-verified 2026-07-23)
|
||||
|
||||
- **Rejected — `tree-sitter-latex` 0.1.0.** Broken repackage; dead declared
|
||||
repo; **no `scanner.c`** for its declared external tokens; proven offline
|
||||
link failure (undefined `tree_sitter_latex_external_scanner_*`). Not
|
||||
linkable at any pin. (F1.)
|
||||
- **Chosen — `codebook-tree-sitter-latex` 0.6.1** (26k downloads,
|
||||
~3.1 MB compressed). A republish **from the codebook project's fork of
|
||||
`latex-lsp/tree-sitter-latex`** (the real, maintained grammar — MIT,
|
||||
texlab's author). The fork **modernized the bindings to the `LanguageFn`
|
||||
shim and renamed the crate**; genuine `latex-lsp` master still carries
|
||||
old-style bindings (`tree-sitter = 0.24.1` as a *direct* dependency, no
|
||||
shim). (Rev 1/2 mis-attributed this to a Dec-2025 upstream `latex-lsp`
|
||||
commit — GitHub serves fork-network objects through the parent repo's
|
||||
commit/contents API, so the fork's commit `948b89c`, whose `lib.rs` already
|
||||
carries the `codebook_tree_sitter_latex` name, looked upstream.) It **ships
|
||||
`scanner.c`**, exports **`LANGUAGE: LanguageFn`** over
|
||||
`tree-sitter-language 0.1` with `tree-sitter` **dev-only** — the exact shim
|
||||
pattern every pmacs grammar uses. Verified end-to-end: builds against
|
||||
`tree-sitter 0.26` and parses a document containing a **verbatim
|
||||
environment** (which exercises the external scanner) → root kind
|
||||
`source_file`, no errors. The canonical name `tree-sitter-latex` is squatted
|
||||
by the broken crate, hence the `codebook-` prefix.
|
||||
- **Provenance diff — run, not deferred (R2-2).** The 0.6.1 crate was diffed
|
||||
against genuine `latex-lsp` master: `grammar.js` and `scanner.c` — the
|
||||
grammar definition and the hand-written C, the security-relevant surfaces —
|
||||
are **byte-identical**. `grammar.json` / `node-types.json` differ **only** by
|
||||
newer tree-sitter-cli output metadata (supertype population, extra flags):
|
||||
**460 node types in both**, with type sets, named flags, and rule counts all
|
||||
identical. The **sole residual** is `parser.c`, which is generated and not
|
||||
committed upstream, so it cannot be diffed — it is exercised by the parse
|
||||
smokes (acceptance 2), and an optional full discharge is regenerating it with
|
||||
`tree-sitter-cli` at implementation time.
|
||||
|
||||
## 3. Decisions
|
||||
|
||||
### Q#LX1 — Bundle `codebook-tree-sitter-latex` 0.6.1
|
||||
|
||||
Add `codebook-tree-sitter-latex = "0.6"` to the `Cargo.toml` grammar block;
|
||||
loader is `|| codebook_tree_sitter_latex::LANGUAGE.into()` (confirmed against
|
||||
the crate's `[lib] name = "codebook_tree_sitter_latex"`). This is the linkable
|
||||
republish from the codebook project's fork of `latex-lsp/tree-sitter-latex`,
|
||||
which modernized the bindings to the `LanguageFn` shim (§2); the
|
||||
originally-named `tree-sitter-latex` 0.1.0 is rejected as unlinkable (§2, F1).
|
||||
ABI is fine via the `tree-sitter-language` shim, exactly as every current
|
||||
grammar. The provenance concern (dirty-tree publish, squatted name) is
|
||||
**discharged, not deferred**: the diff against `latex-lsp` master is
|
||||
byte-identical on `grammar.js`/`scanner.c`, with only tree-sitter-cli metadata
|
||||
drift elsewhere and generated `parser.c` as the sole residual (§2, R2-2).
|
||||
Rejected: vendoring generated `parser.c`/`scanner.c` directly (compile +
|
||||
maintenance burden the crate absorbs) and re-pinning `tree-sitter`
|
||||
(unnecessary — the shim decouples us).
|
||||
|
||||
### Q#LX2 — Vendor nvim-treesitter's highlights query (no first-party source exists)
|
||||
|
||||
latex-lsp ships **no** `queries/` directory and no first-party
|
||||
`highlights.scm` exists anywhere (F3). Vendor **nvim-treesitter's
|
||||
`queries/latex/highlights.scm`** (342 lines, **Apache-2.0** — compatible with
|
||||
pmacs' `MIT OR Apache-2.0`; Helix's MPL-2.0 version is the fallback), host it
|
||||
at `builtin/queries/latex/highlights.scm`, and wire it into the entry's
|
||||
`highlights_query` via `include_str!` (the `audit-rules.scm` precedent). This
|
||||
establishes the first **in-repo grammar-query overlay convention**, which the
|
||||
ruby/php/html/css backlog then reuses.
|
||||
|
||||
The **real work** (F4), beyond copying the file:
|
||||
1. **Capture reconciliation.** Rename/curate the query's `@markup.*`,
|
||||
`@module`, and `@label` captures onto pmacs' recognized set
|
||||
(`src/highlight.rs:189`) or they paint as default — and those are the
|
||||
LaTeX-distinctive captures (headings, emphasis, math, environment names).
|
||||
2. **Predicate curation.** The 8 `#match?`/`#eq?`/`#any-of?`/`#lua-match?`
|
||||
uses are silently ignored (§2); curate them out, or accept the resulting
|
||||
over-matching, per rule.
|
||||
3. **Node-name compatibility.** Acceptance test 3 (`Query::new` compiles the
|
||||
vendored query against the chosen grammar, §6) **doubles as the
|
||||
grammar/query node-name compatibility check** — it is the test that catches
|
||||
a grammar-version/query mismatch.
|
||||
|
||||
Prefer `include_str!` of a `.scm` file over an in-source `&'static str` const
|
||||
so the query stays diffable and lintable as query source.
|
||||
|
||||
### Q#LX3 — Extensions and detection
|
||||
|
||||
`extensions: &["tex", "latex", "sty", "cls"]`. A single `BUILTIN_LANGUAGES`
|
||||
append at `:1095` wires the full detection chain (grammar-extension precedes
|
||||
the LSP filetype map in `syntax.lua:457`). No Lua edit; no
|
||||
modeline/filename/shebang changes.
|
||||
|
||||
### Q#LX4 — Locals and injections empty for v0
|
||||
|
||||
`locals_query: &[]`, `injections_query: &[]`. LaTeX has no lexical-scope
|
||||
locals worth shipping in v0. The `(math_environment) @math` injection — the
|
||||
instance-side, wire-authoritative alternative to the inline-math framing's
|
||||
frontend-local detection — is **deferred to the inline-math arc**; it hooks
|
||||
`collect_injection_matches` (`syntax.rs:375-427`) unchanged when a `"math"`
|
||||
layer exists. Verbatim/`listings`/`minted` code-block injections are a later
|
||||
quality pass.
|
||||
|
||||
### Q#LX5 — The math parser is deferred, not front-run (decided)
|
||||
|
||||
`src/math_parse.rs` (LaTeX math → the `MathNode` AST in
|
||||
`docs/inline-math-framing.md` §Tier 2, **~500 lines** + a ~200-entry symbol
|
||||
map) is pure, dependency-free, and conflict-free. Reviewer and author concur:
|
||||
**defer it** and land it beside its Tier 3 layout consumer. Rationale, beyond
|
||||
the no-build-ahead discipline (folding refuses `BlockAdornments`;
|
||||
gpu-invocation refuses `FILE`):
|
||||
|
||||
- **No design pressure until layout exists.** The parent framing places the
|
||||
hard part in Tier 3 layout; the `MathNode` shape is only validated once
|
||||
layout consumes it. Freezing the AST now risks rework.
|
||||
- **The parallelization argument is void.** The parser is conflict-free *by
|
||||
construction* — it can land at any time without lane contention — so there
|
||||
is nothing to gain by front-running it. Front-running only trades that free
|
||||
optionality for speculative, unexercised code.
|
||||
|
||||
Stage 1 (grammar) therefore is this lane's shippable PR; the parser lands with
|
||||
the inline-math arc. Recorded here so it is not re-opened — the defer is
|
||||
ratified by the user's approval of this framing, per the workflow (author +
|
||||
reviewer concurrence proposes it; approval decides it).
|
||||
|
||||
### Q#LX6 — No protocol, frontend, or GPU change in this lane
|
||||
|
||||
No wire type, no `pmacs-protocol` touch, no TUI/GPU change. Stage 1 is a pure
|
||||
instance-side grammar-table addition. This is what keeps the lane orthogonal
|
||||
to both in-flight efforts.
|
||||
|
||||
## 4. Categorical bets
|
||||
|
||||
1. **The `LanguageFn` shim makes crate-version skew a non-issue.** Every
|
||||
grammar already crosses the `tree-sitter 0.26` boundary through
|
||||
`tree-sitter-language`; `codebook-tree-sitter-latex` is no different —
|
||||
confirmed by a real build. The linkability risk was in the *scanner*, not
|
||||
the shim, and is resolved by choosing a crate that ships `scanner.c` (F1/F2).
|
||||
2. **LaTeX highlighting is worth ~3.1 MB of grammar.** It is the largest
|
||||
single grammar in the tree — a real binary-size and compile-time cost —
|
||||
justified by being the LaTeX-mode foothold and a heavily-used authoring
|
||||
format. A Cargo feature-gate is a v1 escape hatch if the size bites builds
|
||||
that never edit `.tex`.
|
||||
3. **An in-repo query overlay is a convention to establish, not a blocker.**
|
||||
It generalizes to every grammar crate that ships no Rust query constant —
|
||||
directly unblocking the ruby/php/html/css backlog.
|
||||
4. **A verified republish beats a canonical-but-broken name.** The squatted
|
||||
`tree-sitter-latex` name would have been the "obvious" pick and does not
|
||||
link; the provenance diff (Q#LX1, now discharged — grammar and scanner
|
||||
byte-identical to upstream) is the cost, already paid, of using the working
|
||||
republish safely.
|
||||
|
||||
## 5. Deferred (named)
|
||||
|
||||
- **Math parser `src/math_parse.rs`** — decided defer (Q#LX5); lands with
|
||||
Tier 3 layout, not this lane.
|
||||
- **Tier 3 math layout** (`src/math_layout.rs`, a font crate — `read-fonts`
|
||||
or `ttf-parser` — + OpenType MATH-table box layout). New file, no contested
|
||||
touch, but pulls a dependency and has real complexity; belongs to the
|
||||
inline-math arc beside its GPU consumer.
|
||||
- **Tier 4 GPU render** (`pmacs-gpu/src/main.rs` render path). The three-way
|
||||
hotspot; wait for folding and gpu-invocation to settle before opening it.
|
||||
- **Instance-side `(math_environment) @math` injection detection** + a `"math"`
|
||||
`BUILTIN_LANGUAGES` layer (the wire-authoritative upgrade over the framing's
|
||||
frontend-local scan).
|
||||
- **A real `latex-mode.lua`**: texlab LSP config, sectioning folds (rides
|
||||
Arc 6), `\ref`/`\label` navigation, environment/snippet completion,
|
||||
auto-`\end{}`. Full-document LaTeX, not math rendering.
|
||||
- **Curated highlight refinements** beyond the vendored query, including
|
||||
re-instating the ignored predicates should pmacs' predicate support grow;
|
||||
verbatim/`listings`/`minted` code injections.
|
||||
|
||||
## 6. Acceptance
|
||||
|
||||
**Stage 1 (grammar).** Tests follow the CUDA convention
|
||||
(`src/syntax.rs:2130-2221`) + the paint template (`src/highlight.rs:1296`):
|
||||
|
||||
1. **Table guard** `builtin_languages_include_latex`: the entry exists, claims
|
||||
`tex`/`latex`/`sty`/`cls`, and carries the overlay highlights fragment.
|
||||
2. **Load-and-parse smoke** `latex_grammar_loads_and_parses`:
|
||||
`reg.language("latex")`, parse a minimal
|
||||
`\documentclass{article}\begin{document}Hello $x$\end{document}` **plus a
|
||||
`verbatim` environment** (to exercise the external scanner), assert the
|
||||
root node kind `source_file` and `!has_error()`.
|
||||
3. **Highlights resolve + node-name compatibility**
|
||||
`latex_highlights_resolve`: `reg.highlights_query("latex")` compiles the
|
||||
vendored query against the grammar (this is also the grammar/query
|
||||
compatibility gate, Q#LX2), and a `\command`, a `{group}`, and a
|
||||
sectioning/emphasis construct paint the reconciled capture classes (not
|
||||
default).
|
||||
4. **Extension resolution** `language_for_path_resolves_latex_extensions`:
|
||||
`foo.tex` / `foo.latex` / `pkg.sty` / `cls.cls` all resolve to `"latex"`.
|
||||
5. **Full gate suite** per `CLAUDE.md`: `cargo fmt --check`; `cargo clippy
|
||||
--workspace --all-targets -- -D warnings`; `cargo test --lib`; `cargo test
|
||||
--lib --features crdt`; the touched acceptance suites; `cargo test --test
|
||||
m4_acceptance -- --skip basedpyright`; `PMACS_REQUIRE_GPU=1 cargo test -p
|
||||
pmacs-gpu`; `git diff --check`.
|
||||
|
||||
(Stage 2 parser acceptance moves to the inline-math arc with the parser
|
||||
itself, per Q#LX5.)
|
||||
|
||||
## 7. Prior art in pmacs
|
||||
|
||||
- `docs/inline-math-framing.md` — the parent arc; this lane is its Tier 1
|
||||
substrate, with the Tier 2 parser and Tiers 3–4 deferred.
|
||||
- `docs/multi-language-injections-framing.md` / PR #122 — the
|
||||
`ParseTreeBundle` + `Layer` injection engine that a future
|
||||
`(math_environment) @math` capture rides (Q#LX4).
|
||||
- PR #132 (modeline detection) — the extension→language chain
|
||||
(`syntax.lua:452-466`) that a single `extensions` field plugs into.
|
||||
- CUDA grammar (`src/syntax.rs:919-923`, tests `:2130-2221`) — the closest
|
||||
precedent for a multi-fragment highlights query and the grammar test
|
||||
convention; `audit/audit-rules.scm` (`src/audit/mod.rs:76`) — the sole
|
||||
precedent for an `include_str!`-loaded `.scm`.
