Re: [xmonad] A few issues with xmonad I'd like to fix

25 Jul 2011

      Hi,

Thank you for your help on fixing the various issues I had with xmonad. 
  Sorry I didn't send this email sooner.

I have applied your code and it fixed the _very_ annoying regular crash, 
that really did help so thank you again particularly for this :)

I'm still stuck with the xK_section and xK_exclam keys and I'm 
requesting help here again.  The issue I have is simple: I have a really 
hard time understanding the haskell config file.

Here is my config cleaned up a bit: http://pastebin.com/rxbLXaX5 and the 
following line is where I'm stuck:

	, keys = \c -> azertyKeys c `M.union` keys defaultConfig c

Here is what I'd like: set/create at the start of my config 3 distinct 
key bindings in 3 different vars:

	- custom keybindings for the 'sendMessage (JumpToLayout "Tall")' for my 
layouts shortcuts (myLayoutKeys)
	- azerty config (azertyKeys - use the existing xmonad one)
	- custom keybindings for xK_section and xK_exclam (myAzertyExceptionsKeys)

Then I'd like to put it all into one var called myGlobalConfigKeys and 
add it to the main xmonad setup in xmonad.hs :

	xmonad $ defaultconfig
		{
		...
		, keys = myGlobalConfigKeys
		...
		}

So I'm looking for a very simple sample on which I could keep on working 
on it alone.

Sorry for asking this which might seem fairly straightforward but I have 
a very hard time understanding the config file.

To really understand it, I believe that the best would be for me to be 
on voice coms for about half an hour with someone who understands it 
well to talk through the config itself.  I can also learn haskell which 
I would love to do if I have some spare time but it's not the case at 
the moment.  I did the website tutorial but it's still not clear enough 
for me at the moment.

Thank you once again for your help,
Best regards,
Laurent

I was more looking for a small script snippet but I'll dig a bit more ;)
The small script snippet is to follow the import advice outlined there,
then add a keybinding to the action
sendMessage (JumpToLayout "Tall")
for example, for the Tall layout. For other layouts, see the
instructions in the link for finding out what String to put instead of
"Tall".

2) When I ALT-TAB once and release ALT and TAB, I like to go back to
the previous window in the stack instead of going forward again, is
this possible ?
don't understand the request
Forget about this, it's an old Windows habit that I have and it
actually doesn't really translate into xmonad now that I think about it.
Ah, now I know what you're asking for! I think there is functionality
like Windows' alt+tab somewhere, but I can't find it. Perhaps this is
like it?

3) Is there any bypass or automatic script that could do the "# cat
/proc/####/fd/4" thing automatically when xmonad freezes?
Wouldn't it be better to just avoid having xmonad freeze, instead? It
looks like you're sending output to xmobar; does xmobar have a
PipeReader working? Could you paste your .xmobarrc somewhere for us
to take a look at?
Of course, here is my .xmobarrc:
http://pastebin.com/DNzRKyWf
As I suspected, you don't have a StdinReader in use. Either add that as
a plugin and in your xmobar template, or simply remove logging from
xmonad.hs. The latter change would leave your "main" function looking
like this (with "..." in places where you don't need to make changes):
main = xmonad defaultConfig
{ manageHook = ...
, layoutHook = ...
, focusedBorderColor = ...
, normalBorderColor = ...
, borderWidth = ...
-- NO logHook! DELETE it
, startupHook = spawn "/usr/bin/xmobar /home/laurent/.xmobarrc"
, keys = ...
}
You can probably run "spawn" on its own in a do-block as you did before,
but I wasn't sure whether spawn had a X () return type or a MonadIO m =>
m () return type, so I played it safe here and stuck it in the
startupHook. Which you do is a matter of taste.
After you make this change, xmonad should stop locking up.
...
...
In any case, it will help immensely to open up xev, whack your 6 and
8 keys, and take a look at the output there.
Here is the xev output for those two keys (6 = § and 8 = !)
Then perhaps you would like to use xK_section and xK_exclam in your
keybindings.
Good luck!
