omarchy-nvim: only suggest inline when an AI source can

[nico93f]

Stock Omarchy ghosts words at you while you type, and there is nothing behind the guess.

LazyVim defaults vim.g.ai_cmp = true, which routes AI completions through the completion menu and switches on blink.cmp's ghost text so the selected item previews inline. Omarchy enables no AI extra — lazyvim.json lists only editor.neo-tree — so the sources are lsp, path, snippets, buffer, and the inline preview spends its time writing words already on screen back into the line you are typing.

Typing Notes on cons on line 3, stock omarchy-nvim 2026.8.13:

  1   The constitutional convention met in Philadelphia.
  2
  3   Notes on constitutional      <- only "cons" was typed
            constitutional
            convention
          󱄽  caution~

With vim.g.ai_cmp = false:

  1   The constitutional convention met in Philadelphia.
  2
  3   Notes on cons
            constitutional
            convention
          󱄽  caution~

The menu is untouched. Only the text that wrote itself ahead of the cursor is gone.

It is worst in prose. Writing a commit message, a note, a prompt in markdown, the buffer guesses the rest of the word every few keystrokes off nothing but the words already in the file, and the eye follows it every time.

Why this switch rather than turning ghost text off directly

ai_cmp is LazyVim's own flag for exactly this question. Its AI extras read it — copilot, supermaven and codeium all set suggestion.enabled = not vim.g.ai_cmp — so with it off, a user who enables one of those extras gets that provider's native inline suggestions, still accepted with <Tab> through LazyVim.cmp.actions.ai_accept. Inline suggestions when something can genuinely predict the next words; none when nothing can.

Doesn't change

• the completion menu, its sources, its keymaps
• <Tab>, <CR>, <C-y> behaviour
• anything for users who have enabled an AI extra, beyond moving their suggestions from the menu preview to the provider's own inline rendering

Verified

Built nothing — this is config. Ran stock /etc/skel/.config/nvim and the patched copy side by side against the shipped plugin cache; the captures above are tmux capture-pane of those two sessions. require("blink.cmp.config").completion.ghost_text.enabled() returns true before and false after.

Existing installs

~/.config/nvim is user-owned and /etc/skel only seeds new users, so this reaches fresh installs only. Happy to follow up with a migration in basecamp/omarchy that appends the line to an unmodified lua/config/options.lua, in the shape of 1781587663.sh, if you want existing users covered.
