iTerm2 非活动窗口的透明透明背景

Question

本机 MacOS Terminal 能够为非活动和活动窗格设置透明度。 iTerm2 具有活动背景的透明度，由于某种原因，我找不到非活动背景或maybe there isn't any?。我知道，iTerm2 有 DIM inactive split panes，但我正在寻找的是透明度。

感谢您的帮助。

Answer 1

在this blog 上找到了答案，但为了保存，我会在这里重复一遍。

1. 打开 iTerm2 的首选项，使用菜单或 ⌘+,
2. 从菜单栏中选择个人资料
3. 选择窗口标签
4. 拖动透明度滑块以满足您的需要

Answer 2

首选项→外观→调光→调光量

Answer 3

编辑：是原始脚本版本中的一个错误，他们没有处理标签中多个会话的情况。修复和重构:)

前面的每个答案都得到了一块拼图。一个改变透明度，但是是静态的；当窗口处于非活动状态时，其他变暗，而不是更改透明度。

要获得所需的行为（根据窗口焦点更改透明度），您需要使用 iTerm2 的 Python API 编写脚本，并将其保存为 AutoLaunch 脚本：

#!/usr/bin/env python3.7

import iterm2

# Store window change event reason objects in more convenient variables
window_selected = [iterm2.FocusUpdateWindowChanged.Reason.TERMINAL_WINDOW_BECAME_KEY]


async def update_tab_transparency(connection, tab, reason):
    # Apply to any and all sessions in tab
    for session in tab.sessions:
        profile = await session.async_get_profile()
        change = iterm2.LocalWriteOnlyProfile()

        # For window change events bringing a window into focus,
        # change transparency to zero
        if reason in window_selected:
            change.set_transparency(0)

        # For window change events taking a window out of focus,
        # make sure transparency matches the original profile
        else:
            # But, only need to do anything if the profile has been changed
            # from the original
            if profile.original_guid:
                original = await iterm2.Profile.async_get(
                    connection, [profile.original_guid]
                )
                change.set_transparency(original[0].transparency)

        await session.async_set_profile_properties(change)


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

    # Initialize for first window
    window = app.current_window
    if window and window.current_tab:
        tab = window.current_tab
        reason = window_selected[0]
        await update_tab_transparency(connection, tab, reason)

    async with iterm2.FocusMonitor(connection) as mon:
        while True:
            # Block until a tab or window change
            update = await mon.async_get_next_update()

            # When switching to a new tab, treat as selecting a window
            if update.selected_tab_changed:
                tab = app.get_tab_by_id(update.selected_tab_changed.tab_id)
                reason = window_selected[0]

            # For window change events, use the provided event reason
            elif update.window_changed:
                window = app.get_window_by_id(update.window_changed.window_id)
                tab = window.current_tab
                reason = update.window_changed.event

            # For other focus change events, do nothing
            else:
                continue

            if tab:
                await update_tab_transparency(connection, tab, reason)


iterm2.run_forever(main)

有关using Python scripts 的详细信息，请参阅 iTerm 文档

您想在个人资料上设置所需的透明度，并选中“新 Windows 设置”的“使用透明度”框。这听起来违反直觉，但似乎无法通过 API 切换“使用透明度”设置，因此脚本会在创建时快速将窗口切换为不透明。

至少在我的机器上，当第一次选择时，窗口会短暂闪烁，但我不确定我是否能对此做些什么。

注意：macOS 当前（11.6，Big Sur）处理窗口的方式与此相反——它使活动窗口透明（至少，它们的某些部分）和非活动窗口不透明（并褪色）。尝试在 Safari 中打开一个新标签页。这说得通！透明度创造了一种深度感。看到活动窗口后面有窗口强调它在它们前面。

要获得此行为，请使用以下脚本。这种变体更简单，而且运行起来似乎更顺畅（没有闪烁）。如果您将模糊设置为最大，透明度约为 25，则效果最佳。

#!/usr/bin/env python3.7

import iterm2

# Store window change event reason objects in more convenient variables
window_selected = [iterm2.FocusUpdateWindowChanged.Reason.TERMINAL_WINDOW_BECAME_KEY]


async def update_tab_transparency(connection, tab, reason):
    # Apply to any and all sessions in tab
    for session in tab.sessions:
        profile = await session.async_get_profile()
        change = iterm2.LocalWriteOnlyProfile()

        # For window change events bringing a window into focus,
        # make sure transparency matches the original profile
        if reason in window_selected:
            # But, only need to do anything if the profile has been changed
            # from the original
            if profile.original_guid:
                original = await iterm2.Profile.async_get(
                    connection, [profile.original_guid]
                )
                change.set_transparency(original[0].transparency)

        # For window change events taking a window out of focus,
        # change transparency to zero
        else:
            change.set_transparency(0)

        await session.async_set_profile_properties(change)


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

    async with iterm2.FocusMonitor(connection) as mon:
        while True:
            # Block until a window change
            update = await mon.async_get_next_update()
            if update.window_changed:
                window = app.get_window_by_id(update.window_changed.window_id)
                tab = window.current_tab

                if tab:
                    reason = update.window_changed.event
                    await update_tab_transparency(connection, tab, reason)
