This line breaks syntax coloring when editing commit messages

[gonzus]

kickstart.nvim/init.lua

Line 296 in 4a37a0a

highlight = { enable = true },

With this line, when I change one of my repos and then issue a git commit -v command (with $EDITOR set to neovim), the commit message itself has correct syntax coloring, but the diffs shown below the commit message show up as plain gray. Commenting the line out fixes the symptom.

Not reproduced on my end.

Are you using the latest master branch? Or did you add a custom configuration?

[gonzus]

I just recloned from git@github.com:nvim-lua/kickstart.nvim.git into a fresh ~/.config/nvim and tried a git commit -v --amend in one of my git repos; the colors for the commit changes are not there (the commit message itself IS correctly highlighted, though).

I then commented init.lua:296 to look like this, and the commit changes are now properly highlited:

diff --git a/init.lua b/init.lua
index 7289032..04aa472 100644
--- a/init.lua
+++ b/init.lua
@@ -293,7 +293,7 @@ require('nvim-treesitter.configs').setup {
   -- Autoinstall languages that are not installed. Defaults to false (but you can change for yourself!)
   auto_install = false,
 
-  highlight = { enable = true },
+  -- highlight = { enable = true },
   indent = { enable = true, disable = { 'python' } },
   incremental_selection = {
     enable = true,

In case it helps: this is with NVIM v0.8.3 running on zsh 5.9, on arm-apple-darwin22.2.0.

I created a brand new VPS and tried to reproduce the bug, but still couldn't reproduce it.

this is with NVIM v0.8.3 running on bash 5.1.16, on archlinux.

Perhaps you can try cleaning the runtime path cache:

rm -rf ~/.cache/nvim
rm -rf ~/.local/share/nvim
rm -rf ~/.local/state/nvim

⚠️ Please note that the above actions will delete cache files, installed plugins by lazy.nvim, and installed language server by mason. Please use with caution.

Ok, some weird interactions here. I cleaned up those three directories, and let neovim rebuild everything. One of the things it rebuilds are the TreeSitter parsers living in ~/.local/share/nvim/lazy/nvim-treesitter/parser/. The weird things are:

1. Sometimes these parsers are built for x86_64, although I am running under arm. I could not determine exactly how or when this happens.
2. If the gitcommit.so parser does not exist in this directory, and I try to amend a commit, syntax highlighting works 100% fine.
3. If the gitcommit.so parser exists (and is the correct arm type of shared object), and I try to amend a commit, syntax highlighting stops working, and I only see the colors for the commit message.

[kang8]

I know why now.

gitcommit can only parse git commit subject, message and generated, If you want to highlight the diff, you need to execute :TSInstall diff to install diff in tree-sitter.

Hey @kang8 thanks, that at least explains part of the weirdness. So I added diff to the list of TS parsers, and now at least the diff lines are highlighted (diff, index, lines starting with @@); but the actual changed lines of code (and the surounding code context) are not. This is C code, for which I do have the TS parser installed, and when I open one of these C source files they do highlight properly.

I also installed the git_rebase parser, as mentioned in the code you pointed to, but that made no difference.

If I remove the gitcommit TS parser and immediately after I do a git commit -v --amend, two things happen:

1. The diff after the commit message comes up correctly highlighted, in full.
2. nvim notices I am missing the gitcommit parser and installs it for me, but it incorrectly compiles it for x86_64 instead of arm. If I then remove the compiled parser and run nvim again (no args), the missing parser is installed again, this time compiled for the correct arm architecture.

No activity in 1 month. Resolving. Please re-open if you're still having issues and are sure this configuration is responsible.

Update re:

If you want to highlight the diff, you need to execute :TSInstall diff to install diff in tree-sitter.

This is now handled in kickstart.nvim:

• Add diff to treesitter's ensure_installed languages #908
