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
Norg install_info and queries are maintained by neorg.
All other parsers are compatible with C++11, so fix that as standard.
(Can be bumped if all supported platforms support C++14.)
Remove Makefile support, as it's no longer needed.
