打开、拆分 iTerm2 窗口并在每个窗格中执行命令

Question

我正在尝试创建一个脚本，该脚本将打开一个

iTerm2

窗口，将其垂直分成 3 个窗格，并在每个窗格中运行一些命令。

这是我迄今为止的尝试：

tell application "iTerm2"
  activate

  -- Create main window
  create window with default profile

  tell current session of current window
    set name to "frontend"
    write text "cd ~/Documents/frontendDir"
    split vertically with default profile
  end tell

  tell second session of current window -- ERROR HERE
    set name to "backend"
    write text "cd ~/Documents/backendDir"
    split vertically with default profile
  end tell

  tell third session of current window
    set name to "apollo-server"
    write text "cd ~/Documents/GitHub/apolloDir"
  end tell
end tell

关于创建

frontend

的第一部分似乎可以正常工作，因为窗口已正确打开并且命令

cd ~/Documents/frontendDir

在其中正确执行。该窗口也会垂直分割一次，因为我很确定当我尝试访问窗口的第二个窗格时它会停止执行。

我收到此错误：

iTerm got an error: Can’t get session 2 of current window

提前致谢

Answer 1

iTerm

session

对象包含在

tabs

中，而不是

windows

中。因此，正如您在下面的脚本片段中看到的，我通过

current tab

的

current window

引用了要写入的每个会话：

tell application "iTerm"
    activate

    set W to current window
    if W = missing value then set W to create window with default profile
    tell W's current session
        split vertically with default profile
        split vertically with default profile
    end tell
    set T to W's current tab
    write T's session 1 text "cd ~/Desktop"
    write T's session 2 text "cd ~/Downloads"
    write T's session 3 text "cd ~/Documents"
end tell

据我所知，你不能设置

name

的

session

属性；它被设置为会话框架的标题。您可以通过索引引用每个

session

（就像我在这里所做的那样）；它的

id

属性；或其

tty

属性；所有这些都是独特的价值。

如您所见，索引似乎是按会话的创建排序的：

您可以使用Python脚本：

import iterm2

async def main(connection):
    app = await iterm2.async_get_app(connection)
    window = app.current_terminal_window

    # Define base path and project name variables
    base_path = '/Users/username/somefolder'
    project_name = 'projectname'

    if window is not None:
        # Create a new tab
        tab = await window.async_create_tab()
        
        # Store a reference to the left pane (initial session)
        left_panel = tab.current_session

        # Execute command in the top-left pane
        cmd_top_left = f'cd {base_path}; ./docker-{project_name}-run-kernel\n'
        await left_panel.async_send_text(cmd_top_left)

        # Create a right pane by splitting the left one vertically
        right_panel = await left_panel.async_split_pane(vertical=True)

        # Split the right pane into top and bottom panes
        bottom_right_panel = await right_panel.async_split_pane(vertical=False)

        # Execute command in the top-right pane
        cmd_top_right = f'cd {base_path}/{project_name}\n'
        await right_panel.async_send_text(cmd_top_right)

        # Execute command in the bottom-right pane
        cmd_bottom_right = f'docker exec -it {project_name}-puma-1 bash\n'
        await bottom_right_panel.async_send_text(cmd_bottom_right)

        # Split the left pane into top and bottom using the stored reference
        bottom_left_panel = await left_panel.async_split_pane(vertical=False)

        # Execute command in the bottom-left pane
        cmd_bottom_left = f'cd {base_path}; ./docker-{project_name}-run-rails; cd {base_path}/{project_name}\n'
        await bottom_left_panel.async_send_text(cmd_bottom_left)

    else:
        print("No current window")

iterm2.run_until_complete(main)
