我的目标是，当真棒首次运行时，例如在特定标签上自动启动一些程序。在屏幕1，标签1上启动Chromium；在屏幕2的标签1上启动gVim。我在网上找到了一些地方倡导使用以下功能：
function spawn_once(command, class, tag)
-- create move callback
local callback
callback = function(c)
if c.class == class then
awful.client.movetotag(tag, c)
client.remove_signal("manage", callback)
end
end
client.add_signal("manage", callback)
-- now check if not already running!
local findme = command
local firstspace = findme:find(" ")
if firstspace then
findme = findme:sub(0, firstspace-1)
end
-- finally run it
awful.util.spawn_with_shell("pgrep -u $USER -x " .. findme .. " > /dev/null || (" .. command .. ")")
end
spawn_once("chromium", "Chromium", root.tags()[2][1])
spawn_once("gvim", "gVim", root.tags()[1][2])
不幸的是，该功能在新版awesome上不起作用。无论我选择什么标签或对我做的功能进行较小的更新，它都会将程序放在第一个标签上。查看评论：https://gist.github.com/Flowkap/8858434
无法正常工作。与dvd001相同。因此程序在标签1上运行 不管指定的标签如何。
我将如何在真棒（v4.2 +）的较新版本中实现这一目标？

答案 0 :(得分：1)
root.tags（）[2] [1]
这不起作用。尝试例如naughty.notify{ text = "tag is " .. tostring(root.tags()[2][1]) }。它会告诉您这是nil。 root.tags()为您提供了所有标签的简单列表，因此root.tags()[2]是第二个标签。然后，您用[1]将此标签编入索引，这将给您nil（我想...）。
尝试screen[2].tags[1]，假设这是您要表达的内容。
编辑：尝试我们的代码时，我还注意到remove_signal应该是disconnect_signal，而add_signal应该是connect_signal。经过这些更改，现在对git / master来说，这实际上对我有效。
答案 1 :(得分：1)
这里的另一种选择是使用xproperties和支持启动通知的spawn命令。
首先，您需要注册xproperty [1]。之后，您编写一个在运行中的客户端之间循环的函数，并检查是否在这些客户端上设置了属性。如果不是，则使用awful.spawn的第二个参数来设置魔术令牌。请注意，您还可以添加awful.rules源，以解决重启Awesome并基于魔术令牌[2]设置标签时的问题。
对于此解决方案，您需要使用Awesome v4.3 +并应用此技巧：
