It seems upstream neovim 0.10+ is building and installing treesitter parsers for lua and vimdoc (among others), as a part of neovim. However the gentoo ebuild does not build or install these parsers. I think this is because the build step for these parsers is separate from that of neovim, requiring separate cmake & ninja steps in the .deps directory. (BTW the neovim source directory includes a top-level Makefile that calls cmake and ninja appropriately for both the .deps and the main neovim build, so following upstream's build instructions works just fine.) Because treesitter parsers are not installed, the lua filetype plugin attempts to load them, even with an empty RC file $ nvim -u NORC a.lua Error detected while processing BufNewFile Autocommands for "*": Error executing lua callback: /usr/share/nvim/runtime/filetype.lua:35: Error executing lua: /usr/share/nvim/runtime/filetype.lua:36: BufNewFile Autocommands for "*"..FileType Autocommands for "*"..functio n <SNR>1_LoadFTPlugin[20]..script /usr/share/nvim/runtime/ftplugin/lua.lua: Vim(runtime):E5113: Error while calling lua chunk: /usr/share/nvim/runtime/lua/vim/treesitter/language.lua:107: no parser for 'l ua' language, see :help treesitter-parsers Similarly :help throws errors attempting to load vimdoc treesitter parsers: $ nvim -u NORC :help Error detected while processing BufReadPost Autocommands for "*": Error executing lua callback: /usr/share/nvim/runtime/filetype.lua:35: Error executing lua: /usr/shar e/nvim/runtime/filetype.lua:36: BufReadPost Autocommands for "*"..FileType Autocommands for "*"..func tion <SNR>1_LoadFTPlugin[20]..script /usr/share/nvim/runtime/ftplugin/help.lua: Vim(runtime):E5113: E rror while calling lua chunk: /usr/share/nvim/runtime/lua/vim/treesitter/language.lua:107: no parser for 'vimdoc' language, see :help treesitter-parsers
Okay, I've digged into this a bit. There are these CMake flags[0] that installs the tree sitter grammar, USE_BUNDLED_TS_PARSERS to be specific. So basically in upstream they have USE_BUNDLED set to ON and hence neovim installs the required .so files while doing "make install". To reproduce this bug with upstream you can just do > make CMAKE_BUILD_TYPE=RelWithDebInfo USE_BUNDLED=OFF which will not install the treesitter grammars. We already have a PR[1] adding the required grammar's to ::gentoo but it's taking some work. I checked how other distributions install neovim, and most of them have separate grammars and -DUSE_BUNDLED=OFF. So we have to wait for the PR[1] being merged. I've added Vadim (author of the PR) in the CC list for better visibility. [0]: https://github.com/neovim/neovim/blob/b6c1ce8a9545575f8b1ea75e29a4ee9f018e3276/contrib/local.mk.example#L44 [1]: https://github.com/gentoo/gentoo/pull/35461
Or we can do it like Void linux > cmake -S cmake.deps -B .deps -G Ninja -DUSE_BUNDLED=OFF -DUSE_BUNDLED_TS_PARSERS=ON That will install the required grammars that are needed by default.
I tried playing around with -DUSE_BUNDLED=ON and -DUSE_BUNDLED_TS_PARSERS=ON by adding them to the mycmakeargs of the 0.10.0 ebuild, but got " One or more CMake variables were not used by the project", maybe I'm doing something wrong
