Автоматический запуск программ на определенных тегах экрана

Question

Моя цель - автоматически запускать несколько программ по определенным тегам при первом запуске awesome, например запуск Chromium на экране 1, тег 1;запуск gVim на экране 2, тег 1. Я нашел несколько мест в Интернете, в которых рекомендуется использовать следующую функцию:

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])

К сожалению, эта функция не работает в более новых версиях awesome.Независимо от того, какой тег я выбрал или незначительное обновление функции, которую я сделал, программа помещается в первый тег.Смотрите комментарии: https://gist.github.com/Flowkap/8858434

Не работает должным образом.То же, что dvd001.Таким образом, программы запускаются с тегом 1. Независимо от указанного тега.

Как мне поступить в новых версиях awesome (v4.2 +)?

Answer 1

Еще одной альтернативой здесь является использование команд spawn, поддерживаемых xproperties и уведомлением о запуске.

Сначала необходимо зарегистрировать xproperty [1].После этого вы пишете функцию, которая зацикливается на запущенных клиентах и ​​проверяет, установлено ли на них ваше свойство.Если это не так, вы используете второй аргумент awful.spawn, чтобы установить свой магический токен.Обратите внимание, что вы также можете добавить источник awful.rules для решения проблемы при перезапуске Awesome и установке тега на основе магического токена [2].

Для этого решения вам необходимо использовать Awesome v4.3+ и применить этот хак:

Принудительное использование приложений для поддержки уведомлений о запуске

[1] https://awesomewm.org/apidoc/classes/client.html#awful.client.property.persist

[2] https://awesomewm.org/apidoc/libraries/awful.rules.html#add_rule_source

Answer 2

root.tags () [2] [1]

Это не работает.Попробуйте, например, naughty.notify{ text = "tag is " .. tostring(root.tags()[2][1]) }.Он скажет вам, что это nil.root.tags() дает простой список всех тегов, поэтому root.tags()[2] является вторым тегом.Затем вы индексируете этот тег с помощью [1], что даст вам nil (я думаю ...).

Попробуйте screen[2].tags[1], предполагая, что это то, что вы пытаетесь выразить.

Редактировать: пробуя наш код, я также заметил, что remove_signal должно быть disconnect_signal и add_signal должно быть connect_signal.С этими изменениями это теперь действительно работает для меня на git / master.
