Registers a new 'jactoml' language with exact-filename match on
'jac.toml' so every Jaseci project manifest gets proper highlighting
out of the box. Won't touch pyproject.toml, Cargo.toml, etc.
Grammar (syntaxes/jactoml.tmLanguage.json):
- Every table header [...] and [[...]] at any dotted depth is
captured as one whole-path token under
entity.name.tag.jac-known.jactoml. No allowlist, no per-segment
splitting: [dependencies.npm], [plugins.scale.sso.github],
[[plugins.scale.microservices.shared_volumes]] all behave
identically.
- Incomplete '[table' lines (mid-edit) are tagged
invalid.illegal.table.jactoml on the offending line only, so the
color cascade that would otherwise hit every line below is
prevented.
- Shell-style env placeholders (${VAR} and bare $VAR) inside any
string flavor (basic/literal x line/block) are scoped as
variable.other.env.jactoml.
Language configuration (language-configuration.jactoml.json):
- '#' line-comment toggling, bracket matching, autoclose, surround.
Bonus fix: 'Jac: Inspect Token Scopes' was broken
- Existing command threw ENOENT on vendor/onig.wasm on every install
because the wasm was never copied out of node_modules (which
.vscodeignore excludes from the .vsix).
- New copy-wasm npm script (run from both compile and package)
copies the wasm into vendor/onig.wasm. vendor/ is gitignored,
so it's a build artifact.
- Inspector handler generalised to recognise both 'jac' and
'jactoml' languages, picking the correct grammar/scope by
languageId.
Test coverage:
- 250 unit tests pass.
- Covers: universal table capture, dotted paths, arrays-of-tables,
arbitrary non-allowlisted names, ${VAR}/$VAR placeholders in
every string flavor, incomplete-bracket recovery, multiline
strings, dotted-key-vs-table trap, deep nesting, inline tables,
datetime values, empty tables.

Summary
Adds a dedicated
jactomllanguage to the extension so everyjac.tomlproject manifest in the Jaseci ecosystem (jaclang, jacBuilder, jac-scale, jac-byllm, jac-mcp, jac-super, jac-client, jaseci-package, docs, …) gets proper highlighting out of the box, with no dependency on another TOML extension.jactomlregistered with exact filename match onjac.toml(won't touchpyproject.toml,Cargo.toml, etc.).[...]and[[...]](any name, any dotted depth) is captured as one token underentity.name.tag.jac-known.jactoml, so the entire header renders in a single uniform color — no allowlist, no per-segment splitting ([dependencies.npm],[plugins.scale.sso.google],[[plugins.scale.microservices.shared_volumes]]all behave identically).[tableheaders (mid-edit) are taggedinvalid.illegal.table.jactomlon the offending line only — no cascading color loss to lines below.${ECR_REGISTRY},$HOST) inside any string flavor are scoped asvariable.other.env.jactoml.#comments, bracket pairs, autoclose, surround).jac.tomlsupport.Bonus fix:
Jac: Inspect Token Scopeswas brokenExisting command threw
ENOENT: .../vendor/onig.wasmon every published install because the wasm was never copied out ofnode_modules(which.vscodeignoreexcludes from the .vsix). Fixed by:copy-wasmnpm script (run from bothcompileandpackage) that copiesnode_modules/vscode-oniguruma/release/onig.wasmintovendor/onig.wasm.vendor/is gitignored, so the wasm is a build artifact, not a committed binary.jac(.jac) andjactoml(jac.toml) languages, picking the correct grammar and scope automatically.
