smart-ime.nvim

Smart per-buffer IME switching for Neovim.

Features

• Per-buffer IME state
  Remembers input method state separately for each buffer.

• Automatic IME switching

  • Switches to English when leaving Insert mode
  • Restores previous IME when re-entering Insert mode

• Focus-aware normalization
  Ensures IME state is consistent when Neovim regains focus.

• Async & non-blocking
  Uses vim.system() for asynchronous IME querying and switching.

• Optional logging
  Integrates with logger.nvim when available.

• Minimal & predictable behavior
  Reacts only to editor events, no background polling.

How it works

1. On InsertLeave, the current IME state is queried and saved per buffer.
2. IME is switched to English to ensure normal-mode safety.
3. On InsertEnter, the previously saved IME state is restored.
4. On focus gain (FocusGained), IME state is normalized based on current mode.

Installation

Using nvim-plug:

return {
    'wsdjeg/smart-ime.nvim',
    opts = {
        imselect = '~/bin/im-select-mspy.exe',
    },
}
