Problem: Gitlab has too frequent outages, which break automation.
Solution: Drop all Gitlab-hosted parsers (two of which have been
unmaintained for years).
Problem: The commit fc37d05c36 broke parsing a textobjects query.
Solution: Downgrade parser to previous commit and pin it (until we can move it to tier 1).
* supported parsers _must_ commit at least `grammar.json`
* set `TREE_SITTER_JS_RUNTIME=native` when generating parser to use
built-in quickjs instead of node (requires tree-sitter 0.26)
Breaking changes:
- Node `(variable)` was renamed to `(expr_double_quotes)`.
- Node `(variable_raw)` was renamed to `(expr_single_quotes)`.
- Node `(string)` was renamed to `(str_double_quotes)`.
- Node `(raw_string)` was renamed to `(str_single_quotes)`.
- Node `(raw_string_quote)` was removed.
Problem: Using git for installing parsers can lead to data loss if in a
git commit buffer.
Solution: Only support downloading via curl+tar, which are installed on
all supported platforms (since Windows 10). Curl will also be required
for WASM parsers (and for `vim.net.download()`).
Problem: Tracking parser revision in lockfile and allowing override
through the parsers module complicates the code. In addition, only
revision changes are handled robustly, not changes to other installation
info.
Solution: Track parser revision in the parsers module directly. Reload
parser table on every install or update call. Support modifying parser
table in a `User TSUpdate` autocommand.
Problem: Many parsers require node/npm to evaluate the `grammar.js`
before being able to generate a parser from it.
Solution: Generate from `grammar.json` instead, which is fully resolved.
Drops `node` and `npm` as (optional) requirements for nvim-treesitter.
Note that this requires parsers to commit the generated json iff the
grammar requires evaluation (which is currently the case for all tracked
languages).
Tier 1: Stable
Tier 2: Core (maintained by org members)
Tier 3: Community (maintained by external contributors, to varying
degree)
Tier 4: Unsupported (lacking active maintainer or declared
experimental); skipped in lockfile update and ignored for automatic
install by default
