omarchy-nvim: treesitter query error due to missing compiled vim parser

[ki11e6]

Problem

Opening Neovim shows a treesitter query error on startup, which blocks normal usage (:q doesn't work because noice.nvim captures the error into a floating window):

/usr/share/nvim/runtime/lua/vim/treesitter/query.lua:373: Query error at 113:4. Invalid node type "tab":
  "tab"
   ^

Cause

The omarchy-nvim package (v2026.3.27) ships nvim-treesitter at commit 8cdffc6d which added "tab" as a vim command node type in runtime/queries/vim/highlights.scm (line 113). However, the data/site/ directory in the package is empty — no compiled treesitter parsers are included.

This means omarchy-nvim-setup copies an empty site/ directory to ~/.local/share/nvim/site/, so Neovim falls back to the vim parser bundled with the neovim Arch package (0.11.7). That system parser is older and doesn't have "tab" in its grammar, causing the query validation error.

Details

• neovim package: 0.11.7-1
• omarchy-nvim package: 2026.3.27-1
• Packaged nvim-treesitter expects vim parser revision 3092fcd99eb87bbd0fc434aa03650ba58bd5b43b
• System vim parser revision: 3dd4747082d1b717b8978211c06ef7b6cd16125b
• /usr/share/omarchy-nvim/data/site/ is empty (no compiled parsers shipped)

Workaround

Running :TSInstall! vim inside Neovim installs the correct parser version and resolves the error.

Suggested Fix

Either ship the compiled treesitter parsers in omarchy-nvim's data/site/ directory, or add a TSUpdate / TSInstall! vim step to the setup/migration process.

I can't replicate any of this on existing or new installs. Neither on 0.11 or 0.12.

Got the same error after update to Omarchy 3.6.0 > 1st nvim start post-update launched into lazyvim updates which apparently did not finish (can't reproduce) > getting the described error in later nvim runs.

TSUpdate fixed it.
