ne keycodes

Mittwoch, 24. August 2011

To get expected behaviour for home, end and backspace in ne with rxvt-unicode, start ne (the "nice editor"), press Ctrl+k for the command prompt, enter kc and in the new prompt press the specific key for the key code. Afterwards adjust the config file:
>cat .ne/.keys
KEY 105 MoveSOL
KEY 106 MoveEOL
KEY  7f Backspace
Mit der Entwicklung von dwm war ich schon eine Weile unzufrieden, Xmonad hingegen hat sich seit meinem ersten Versuch vor drei Jahren inzwischen zu einem richtigen Metafenstermanager entwickelt. Nahezu jede Funktion ist anpassbar und bereits in mehreren Varianten verfügbar, ganz ohne C schreiben oder veraltete Patches anpassen zu müssen. Sehr, sehr nett.

Die erste .xmonad/xmonad.hs - weitestgehend zusammenkopiert aus der Doku:

import XMonad
import XMonad.Actions.CopyWindow
import XMonad.Actions.DwmPromote
import XMonad.Hooks.DynamicLog

-- certain contrib modules.

-- Whether focus follows the mouse pointer.
myFocusFollowsMouse :: Bool
myFocusFollowsMouse = True

-- Width of the window border in pixels.
--
myBorderWidth   = 1

-- modMask lets you specify which modkey you want to use. The default
-- is mod1Mask ("left alt").  You may also consider using mod3Mask
-- ("right alt"), which does not conflict with emacs keybindings. The
-- "windows key" is usually mod4Mask.
--
myModMask       = mod4Mask

-- The mask for the numlock key. Numlock status is "masked" from the
-- current modifier status, so the keybindings will work with numlock on or
-- off. You may need to change this on some systems.
--
-- You can find the numlock modifier by running "xmodmap" and looking for a
-- modifier with Num_Lock bound to it:
--
-- > $ xmodmap | grep Num
-- > mod2        Num_Lock (0x4d)
--
-- Set numlockMask = 0 if you don't have a numlock key, or want to treat
-- numlock status separately.
--
myNumlockMask   = mod2Mask

-- The default number of workspaces (virtual screens) and their names.
-- By default we use numeric strings, but any string may be used as a
-- workspace name. The number of workspaces is determined by the length
-- of this list.
--
-- A tagging example:
--
-- > workspaces = ["web", "irc", "code" ] ++ map show [4..9]
--

myWorkspaces    = ["1","2","3","4","5:www","6:min"]

Der Ressourcenverbrauch ist höher, aber wenn ich dadurch schneller arbeiten kann, ist es mir egal.

Gleiches gilt für mrxvt. Ein paar Bugs nervten auf Dauer (zB. Zeichenverlust beim Ändern der Fenstergröße) und die Dämonvariante urxvtd wird dem Tiling-Konzept meiner Meinung nach besser gerecht.
