Does awesome window manager set some kind of flag during restart. I've some autostart commands in rc.lua and they are executed every time I restart the window manager.
How can I determine in the rc.lua if the file execution is done because of a restart?
Awesome v4.x?
Declare a run_once function.
numlockx on as an example
function run_once(cmd)
findme = cmd
firstspace = cmd:find(" ")
if firstspace then
findme = cmd:sub(0, firstspace-1)
end
awful.spawn.with_shell("pgrep -u $USER -x " .. findme .. " > /dev/null || (" .. cmd .. ")")
end
run_once("numlockx on")
Sorry, just want to comment @ploth 's answer...but not enough reputation. The given code is the one on the former wiki, and it didn't work for me. I use this one :
function run_once(cmd)
local findme = "ps x U $USER |grep '" .. cmd .. "' |wc -l"
awful.spawn.easy_async_with_shell( findme ,
function(stdout,stderr,reason,exit_code)
if tonumber(stdout) <= 2 then
awful.spawn( cmd )
end
end)
end
Use the included spawn.once function, e.g.
awful.spawn.once("dex --autostart --environment awesome")
