Re: Execute command and wait until it's execution finishes
Please do not use os.execute in rc.lua, it is a blocking function and *ALL* application will lock until the function return. Even if the command is fast, they all add up and, milliseconds by milliseconds, make your computer less responsive. On Aug 11, 2015 2:31 PM, "Jayson Willson" wrote: > That's wonderful!

os.execute is what you want in this case.

Re: Execute command and wait until it's execution finishes
Hello, You can use my async module located here https://github.com/Elv13/awesome-configs/blob/master/utils/fd_async.lua It has lots of non-blocking async functions to do things like you want. However be warned many people report it segfault Awesome in some situations. This seem to be caused by various LGI bugs and maybe a few introduced by my code too. It is stable enough for my use case, but I totally acknowledge some corner cases can cause segfaults. On 10 August 2015 at 14:06, Jayson Willson wrote: > Actually, there is no reason not to use them.

Actually, there is no reason not to use them. I just do not know, if this way is the correct and the optimal one. And, really, I do not know what "pipe" is.. :-) -- To unsubscribe, send mail to awesome-unsubscr...@naquadah.org.
Re: Execute command and wait until it's execution finishes
Hi Jayson,
Using pipes seems to me like a great way to do it, why don't you want to
use pipes?

Execute command and wait until it's execution finishes
Hello! I need the following: execute some command and go to the next
command of the function only when the first command is finished.
What I have now:
awful.key({}, "XF86AudioMute",
function ()
awful.util.spawn("amixer set Master toggle")
update_volume(volume_widget)
end)
Thus "update_volume" takes place earlier, than "amixer set Master
toggle" finishes it's execution, and I do not get required result.
One guy suggested using popen:
function ()
local f = io.popen("amixer set Master toggle")
f:close()
update_volume(volume_widget)
end)
It works fine, but I wonder if there is a way to implement it without
pipes. Could you please help me? Thank you.
