Details

The tree-sitter package installs the `tree-sitter` command-line program, which contains several useful subcommands for writing and using programming language parsers. Some of these subcommands have additional dependencies [1], which are not currently listed in tree-sitter's Arch package.

[1] https://tree-sitter.github.io/tree-sitter/creating-parsers#dependencies

The `tree-sitter generate` subcommand generates the C implementation of a particular language's parser from its grammar definition. The grammars are written in a JavaScript DSL, and this subcommand shells out to `node` to execute the DSL. Per the documentation, nodejs >= 6.0 is needed. (No additional JS packages are required, just the node runtime.)

Several subcommands (including `tree-sitter parse` and `tree-sitter tags`) look for grammar definitions in a user-configurable location, and will generate and compile the grammars on the fly if needed. This requires a C compiler. Is there a generic "C compiler" pseudo-package that we could list as a dependency? If not we could list gcc and/or clang specifically.

In all of the above, the tree-sitter command should fail gracefully if the required programs are not available, which suggests that these should all be listed as optional dependencies.

Thanks!

Considering the package currently already depends on gcc-libs, I don't know if it's worth adding a clang optdep.
