bug: `E5113: Error while calling lua chunk: /usr/share/nvim/runtime/lua/vim/treesitter/language.lua:103: no parser for 'vimdoc' language`

[xfzv]

When entering Kitty's scrollback history with <C-S-h> and either: yanking, pressing i or a, I keep getting the following error:

Error detected while processing FileType Autocommands for "*"..function <SNR>1_LoadFTPlugin[20]..script /usr/share/nvim/runtime/ftplugin/help.lua:
E5113: Error while calling lua chunk: /usr/share/nvim/runtime/lua/vim/treesitter/language.lua:103: no parser for 'vimdoc' language, see :help treesitter-parsers
stack traceback:
        [C]: in function 'error'
        /usr/share/nvim/runtime/lua/vim/treesitter/language.lua:103: in function 'add'

        vim/_editor.lua: in function <vim/_editor.lua:0>

Then the yanked content appears in kitty-scrollback window and I can perform the regular actions (Execute / Paste). If toggling mappings twice with g?, the error occurs again.

Note that I can't reproduce on my Arch Linux VM with similar setup (NVIM v0.10.0-dev-1988+g1ef60ea65-dirty, same Kitty and kitty-scrollback.nvim config). Only occurs on my main system with Gentoo.

Could it be an issue with dev-libs/tree-sitter package specifically on Gentoo?

Maybe this has nothing to do but I do have the vimdoc parser installed:

I tried to reinstall it with :TSInstall vimdoc but it doesn't make any difference, the error persits.

@xfzv interesting. The footer is using the filetype help for the highlights. Can you try :TSInstall vim ?

I think it uses vim instead of vimdoc. To be honest, I am not sure what the difference is.

Edit: vimdoc is for help files, vim is for vimscript.

[mikesmithgh]

@xfzv how are you installing Neovim, are you building from source? I was able to reproduce by manually removing vimdoc.so in neovim/build/lib/nvim/parser/. (I build Neovim from source).

Edit: https://neovim.io/doc/user/treesitter.html#treesitter-parsers

By default, Nvim bundles parsers for C, Lua, Vimscript, Vimdoc and Treesitter query files

I think your Neovim build may be missing the standard vimdoc treesitter parser that is supposed to come bundled with it.

[xfzv]

how are you installing Neovim, are you building from source?

Yes, using the ebuilds from Gentoo repository. Turns out I don't have the error anymore after switching from 9999 (pretty much Git version) to 0.9.4.

Both ebuilds are almost identical, I have no idea why the issue only occurs with the Git version.

Well, feel free to close. As always, thank you for your help! :+1:

Edit: I found https://github.com/neovim/neovim/issues/26379, maybe related

However, rebuilding Neovim with either -DUSE_BUNDLED=OFF or -DUSE_BUNDLED=ON doesn't make any difference:

src_configure() {
    ln -s "${BROOT}"/usr/bin/luajit "${BUILD_DIR}"/luajit || die
    # Upstream default to LTO on non-debug builds
    # Let's expose it as a USE flag because upstream
    # have preferences for how we should use LTO
    # if we want it on (not just -flto)
    # ... but allow turning it off.
    # TODO: Investigate USE_BUNDLED, doesn't seem to be needed right now
    local mycmakeargs=(
+               -DUSE_BUNDLED=OFF
# or
+               -DUSE_BUNDLED=ON
        -DENABLE_LTO=$(usex lto)
        -DPREFER_LUA=$(usex lua_single_target_luajit no "$(lua_get_version)")
        -DLUA_PRG="${ELUA}"
    )

}

@xfzv good find! I subscribed to that issue. I'll keep this open for a little while in case anyone else has something similar 👍.

Note: I just saw this on the nightly CI build.

[xfzv]

Thanks for the heads-up!

I guess installing tree-sitter-vimdoc should be enough to get rid of the error. It doesn't seem to be available on Gentoo though, so I can't try.

[xfzv]

Sorry for the bump but I'm still getting the error on both Gentoo and Arch Linux with different Neovim versions. vimdoc parser is installed:

Hey @xfzv, I'll try and see if I can play around a bit to reproduce. I'm on a Mac so I'll probably use UTM to install Gentoo. I've been a little busy of late so may take a few days to get around to it. Thanks!

[mikesmithgh]

@xfzv thanks for the additional info! I'll try to carve out some time to investigate this. Feel free to post more info as you find it.

[xfzv]

The issue is finally solved for me. :tada:

app-editors/neovim-9999 ebuild was updated a few days ago. Bumping dev-libs/tree-sitter-query and dev-libs/tree-sitter-vimdoc versions did the trick, no more errors:
