Trying to add tree-sitter/tree-sitter-c

[peterjmorgan]

I've tried to follow the instructions perfectly, but I've never used nix before this.

I added the following stanza to flakes.nix:

  tree-sitter-c = {
      url = "github:tree-sitter/tree-sitter-c";
      flake = false;
    };

and the following line to the updateVendor stanza:

ln -s ${inputs.tree-sitter-c} vendor/tree-sitter-c

then ran direnv reload. I don't see an operation happening that is fetching the git repo from github, so I feel like I'm missing something (perhaps obvious).

The update-vendor script runs, but never finds a path in /nix/store that has tree-sitter-c so it cannot update the symlink to the vendor directory.

I'm stuck here, and hoping a nudge in the right direction might help me progress.

Hey Peter! Sorry you're having trouble here. Good news: I tried copying/pasting your snippets myself and it looks like it works. Here's how I can tell:

• after I run direnv reload, I see a new entry in flake.lock that contains the tree-sitter-c hashes. (I pasted your snippet after line 62 in the file, but really it should be alphabetically first.)
• after direnv reload succeeds, running update-vendor creates vendor/tree-sitter-c

If you can see those two things as well, I think you're good to go. Otherwise, could you clarify on this by pasting the exact error message you're seeing?

(note, however: I'm out of the office this week so I will probably be slow to respond again. It looks like you're on the right path here, though, so hopefully it's OK!)

@BrianHicks Thank you! For some reason, direnv wasn't triggering. It worked spontaneously the next time I tried, and yes, everything worked wonderfully. I got tree-sitter-c added and going to add python next :)

I will setup a PR soon if you're interested

[BrianHicks]

yes, that'd be just fine! Until/unless we do something like #88 it'll always be fine to add more languages.
