Creating source code tarball fails due to use of absolute path

[nwhetsell]

Commit cd7cd64 changed the creation of the source code tarball to use this definition of src_dir:

workflows/.github/workflows/release.yml

Line 81 in cd7cd64

: "$(dirname "$grammar")"; : "${_/\./}"; src_dir="$_${_:+/}src"

I am by no means a Bash expert, but what seems to be happening is:

1. $grammar (defined in an enclosing while loop) is passed to dirname and expanded in a string. The resulting string will usually—but not always—be the current folder . (because most Tree-sitter grammars have a grammar.js file in their top-level folder). In some grammars (like TypeScript), the resulting string will be a subfolder of the current folder (like ./tsx or ./typescript).

2. The special Bash variable _ is expanded in a string using ${parameter/pattern/string} expansion. The effect is to remove periods from the result of $(dirname "$grammar"). For grammars like TypeScript, the result is /tsx or /typescript (without leading periods).

3. The variable src_dir is assigned the value formed by concatenating:

   • the Bash variable _ (which is now /tsx or /typescript)
   • the path separator / (unless _ is null or unset)
   • src

The result is that, for grammars like TypeScript, src_dir is an absolute path (/tsx/src or /typescript/src). This causes the release action to fail for similarly-formed grammars:

(The TypeScript grammar was last updated in Nov 2024, well before commit cd7cd64 (Aug 2025), so this issue hasn’t had an opportunity to occur there yet.)

@ObserverOfTime can you revert/fix it? It breaks markdown build: https://github.com/ggodlewski/tree-sitter-markdown/actions/runs/19938150376/job/57168631697
