example config file format

[app]

# Format: "Application Name" = "InputSourceID"
#
# Terminal = "com.apple.keylayout.ABC"
# Safari = "com.apple.inputmethod.SCIM.ITABC"

[debug]
# Enable debugging
enabled = false
# Log level: trace, debug, info, warn, error
level = "info"
# Log file path

• -s with switch input source id
• -p print all available input source list with localized name if found.

Asynchronously auto-switch the input source after leaving insert mode. After the switch is complete, regardless of whether the switch succeeds or fails, iswitch will check if an iswitch process is already running. If no iswitch process is found, iswitch will not exit; it will remain running.

vim.api.nvim_create_autocmd('InsertLeave', {
  callback = function()
    if vim.fn.executable('iswitch') == 0 then
      return
    end
    vim.system({ 'iswitch', '-s', 'com.apple.keylayout.ABC' }, nil, function(proc)
      if proc.code ~= 0 then
        vim.notify('Failed to switch input source: ' .. proc.stderr, vim.log.levels.Warn)
      end
    end)
  end,
  desc = 'auto switch to abc input',
})
