-- Configuring Xmonad

--------------------------------------------------------------------------------
{- $configure
#Configuring_xmonad#
xmonad can be configured by creating and editing the Haskell file:
> ~/.xmonad/xmonad.hs
If this file does not exist, xmonad will simply use default settings;
if it does exist, xmonad will use whatever settings you specify. Note
that this file can contain arbitrary Haskell code, which means that
you have quite a lot of flexibility in configuring xmonad.
NOTE for users of previous versions (< 0.5) of xmonad: this is a major
change in the way xmonad is configured. Prior to version 0.5,
configuring xmonad required editing an xmonad source file called
Config.hs, recompiling xmonad, and then restarting. From version 0.5
onwards, however, you should NOT edit this file. All you have to do
is edit xmonad.hs and restart with @mod-q@; xmonad does the
recompiling itself. The format of the configuration file has also
changed; it is now simpler and much shorter, only requiring you to
list those settings which are different from the defaults.
-}
{- $example
#A_simple_example#
Here is a basic example, which starts with the default xmonad
configuration and overrides the border width, default terminal, and
some colours:
> --
> -- An example, simple ~/.xmonad/xmonad.hs file.
> -- It overrides a few basic settings, reusing all the other defaults.
> --
>
> import XMonad
>
> main = xmonad $ defaultConfig
> { borderWidth = 2
> , terminal = "urxvt"
> , normalBorderColor = "#cccccc"
> , focusedBorderColor = "#cd8b00" }
This will run \'xmonad\', the window manager, with your settings
passed as arguments.
Overriding default settings like this (using \"record update
syntax\"), will yield the shortest config file, as you only have to
describe values that differ from the defaults.
As an alternative, you can copy the template @xmonad.hs@ file (found
either in the @man@ directory, if you have the xmonad source, or on
the xmonad wiki at
@http:\/\/haskell.org\/haskellwiki\/Xmonad\/Config_archive\/Template_xmonad.hs@)
into your @~\/.xmonad\/@ directory. This template file contains all
the default settings spelled out, and you should be able to simply
change the ones you would like to change.
To see what fields can be customized beyond the ones in the example
above, the definition of the 'XMonad.Core.XConfig' data structure can
be found in "XMonad.Core".
-}
{- $check
#Checking_whether_your_xmonad.hs_is_correct#
After changing your configuration, it is a good idea to check that it
is syntactically and type correct. You can do this easily by using an xmonad
flag:
> $ xmonad --recompile
> $
If there is no output, your xmonad.hs has no errors. If there are errors, they
will be printed to the console. Patch them up and try again.
Note, however, that if you skip this step and try restarting xmonad
with errors in your xmonad.hs, it's not the end of the world; xmonad
will simply display a window showing the errors and continue with the
previous configuration settings. (This assumes that you have the
\'xmessage\' utility installed; you probably do.)
-}
{- $load
#Loading_your_configuration#
To get xmonad to use your new settings, type @mod-q@. (Remember, the
mod key is \'alt\' by default, but you can configure it to be
something else, such as your Windows key if you have one.) xmonad will
attempt to compile this file, and run it. If everything goes well,
xmonad will seamlessly restart itself with the new settings, keeping
all your windows, layouts, etc. intact. (If you change anything
related to your layouts, you may need to hit @mod-shift-space@ after
restarting to see the changes take effect.) If something goes wrong,
the previous (default) settings will be used. Note this requires that
GHC and xmonad are in your @$PATH@.
