Problem: Not easy to run all checks and tests locally. Redundant CI
workflows.
Solution: Separate CI into two workflows:
* lint: Lua files (stylua, luals), query files (valid captures,
predicates, directives using tsqueryls), docs
(SUPPORTED_LANGUAGES.md) -- does not need parser installation
* tests: parsers (ABI compatibility), query files (tsqueryls on
Linux/macOS; nvim on Windows), highlight and indent tests (separated
for better readability) -- needs parser installation (but only once)
Switch to https://github.com/nvim-treesitter/highlight-assertions fork
with ABI 15 support.
Run all tests (on Linux and macOS) through `make` (`formatlua`,
`checklua`, `lintquery`, `formatquery`, `checkquery`, `docs`, `tests`),
which downloads and caches all necessary dependencies.
Remove `update-readme` workflow (replaced by lint job on PRs).
* Ignore tags file in project root
* Make :TSInstall work with Nix
This commit adds logic to determine where to install parsers, meaning
the *.so files. Until now the package path of the nvim-treesitter plugin
was used. But when installed with Nix, the plugin lands in "/nix/store",
which is read-only.
With this commit $XDG_DATA_HOME/nvim/site/parser/*.go will be used as
the parser installation path. The directory will be created if it
doesn't exist.
* Add generate_join function
The generate_join function is used to create two other functions, one
to join path segments, the other to join strings with a space for error
messages.
