# kde2wmaker.pl:
|
|
#
|
|
#
|
|
# This script, made for users of Window Maker (http://windowmaker.org) is to
|
|
# be used along with KDE (http://www.kde.org).
|
|
#
|
|
#
|
|
# The default directory, /usr/share/applnk, will contain various
|
|
# sub-directories such as Development, Editors, Internet, etc. If for some
|
|
# reason, you wish to use an alternate (parent) directory that contains the
|
|
# various applnk files, it can be specified on the command line.
|
|
#
|
|
# The directory, if an alternate is specified, MUST be a parent directory to
|
|
# any/all sub-directories.
|
|
#
|
|
# Usage: kde2wmaker.pl [ Options... ]
|
|
#
|
|
# Options:
|
|
#
|
|
# -d <KDE App.kdelnk dir>
|
|
# -f <output menufile>
|
|
# -t <X terminal application>
|
|
#
|
|
# When the script is run, it will write out a proper Window Maker "External
|
|
# Menu" entry, that can be included in the menu. When the External Menu has
|
|
# been correctly configured, the root menu will display a sub-menu containing
|
|
# all of the KDE related items found. The script only needs to be run when/if
|
|
# KDE is updated.
|
|
#
|
|
#
|
|
# Installation and Configuration:
|
|
#
|
|
# 1) If /usr/bin/perl is not the location of the perl binary on your system,
|
|
# the first line should be changed to reflect upon it's location.
|
|
# 2) Run the script.
|
|
# 3) Configure Window Maker's menu by editing ~/GNUstep/Defaults/WMRootMenu
|
|
# This could be done with any text editor, or by using WPrefs. Insert
|
|
# the following line (if done with a text editor) into the WMRootMenu file.
|
|
# ("External Menu", OPEN_MENU, "$HOME/.kde2wmaker.menu"),
|
|
# If done using WPrefs, simply "Add External Menu" from the drop down menu,
|
|
# then type: $HOME/.kde2wmaker.menu into the "Menu Path/Directory List"
|
|
# textbox.
|
|
# 4) Some KDE entries, such as "Pine" will require a terminal to
|
|
# execute it. There is a terminal variable below. You may use any
|
|
# terminal, XTerm is the default. Any command line options such as:
|
|
# -fg -bg, etc. can be specified in this variable as well.

#
|
|
# 21st January 2001.
|
|
#
|
|
# This script has been competely re-written to allow recursion of the
|
|
# KDE menu directories to an arbitrary depth, fixing a major
|
|
# functional limitation in the original script. To do this, I have
|
|
# rewritten the code to traverse directories recursively, introducing
|
|
# a subroutine, process_dir() to carry out the task.
|
|
#
|
|
# wkdemenu.pl provides an excellent extension to the user interface in
|
|
# Window Maker, working well with the "Generated Submenu" feature.
|
|
#
|
|
#
|
|
# Summary of New Features
|
|
# -----------------------
|
|
#
|
|
# Added support for menus of arbitrary depth.
|
|
#
|
|
# Added basic internationalisation based on KDE's language
|
|
# setting. The language is taken from "~/.kde/share/config/kdeglobals"
|
|
# or from "~/.kderc".
|
|
#
|
|
# Corrected the generation of menu names, incorporating
|
|
# internationalisation, where appropriate.
|
|
#
|
|
# Changed the double quotes to two single quotes in application names
|
|
# so that they do not break the Menu parser in Window Maker.
|
|
#
|
|
# Stripped off the arguments to commands on the Exec= line, except in
|
|
# a few KDE specific cases (e.g. kfmclient). The extra options are
|
|
# only usable by KDE and were preventing many applications from
|
|
# launching, since they could parse the option %c or %s, for example.
|
|
# This "feature" will probably need a more formal or interactive way
|
|
# of specifying exceptions in the future.
|
|
#
|
|
# Added a command line option for specifying the X terminal to
|
|
# use. This still defaults to xterm, but could be used to specify
|
|
# aterm, etc.
|
|
#
|
|
#
|
|
# To Do
|
|
# -----
|
|
#
|
|
# Programmatically determine the system location for the KDE menu
|
|
# directory.
|
|
#
|
|
# Organise the output alphabetically, with directories appearing
|
|
# before files.
|
|
#
|
|
# Find a better way to parse the Exec= lines. In the short term,
|
|
# provide a user mechanism for generating exceptions to the curtailing
|
|
# of command line options. In the longer term, emulate what KDE does
|
|
# with these command line features.
|
|
#
|
|
# Optimise the code. This is my first proper PERL script, and I'm sure
|
|
# there's a better way. =)
