feat: add im-select.nvim with terminal-compatible config#20
Merged
Conversation
Add im-select.nvim plugin to automatically switch input method to English when leaving insert mode and restore previous input method when entering insert mode. Changes: - Add nvim/lua/plugins/im-select.lua configuration - Install im-select via Homebrew in nvim_setup.sh - Deploy im-select.lua to ~/.config/nvim/lua/plugins/ during setup - Support all input methods (Korean, Japanese, Chinese, etc.) The plugin automatically detects and handles any non-English input method, switching to English (com.apple.keylayout.ABC) in normal mode and restoring the previous input method in insert mode.

im-select is not available in the main Homebrew repository. It requires tapping daipeihust/tap first. Changes: - Replace direct brew_install with explicit tap + trust + install sequence - Add idempotency check with command -v im-select - Handle trust requirement for third-party tap Verified idempotent: running the script multiple times shows "im-select already installed" without attempting reinstallation.

Extract the tap + trust + install pattern into a reusable helper function in common.sh, similar to brew_install and brew_install_cask. Changes: - Add brew_tap_and_install(tap, formula) helper to common.sh - Simplify nvim_setup.sh to use one-line brew_tap_and_install call - Maintain idempotency with command -v check inside the helper This makes it easier to install formulae from third-party taps in the future.

- Simplify im-select events: remove FocusGained/VimEnter (caused timing issues with snacks terminal double-Esc), remove set_previous_events - Add TermLeave to set_default_events so IM switches to ABC when leaving any terminal buffer (raw :terminal or snacks terminal) - Add idempotent keymaps.lua setup in nvim_setup.sh: appends double-Esc → <C-\><C-N> keymap for raw :terminal buffers via append_line_if_missing Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
