   8 # Modified by Peter Clifton to allow icons with numerals in the filename
   9 #
  10 # This script is meant to be invoked from within a Makefile/Makefile.am
  11 # in the install-data-local and uninstall-data sections. It handles the
  12 # task of properly installing icons into the icon theme. It requires a
  13 # few arguments to set up its environment, and a list of files to be
  14 # installed. The format of the file list is critical:
  15 #
  16 # <category>,<local-src-file-name>
  17 #
  18 #   apps,music-player-banshee.svg
  19 #   apps,music-player-banshee-16.png
  20 #   apps,music-player-banshee-22.png
  21 #
  22 # <category> is the icon theme category, for instance, apps, devices,
  23 # actions, emblems...
  24 #
  25 # <local-src-file-name> must have a basename in the form of:
  26 #
  27 #   proper-theme-name[-<SIZE>].<EXTENSION>
  28 #
  29 # Where <SIZE> should be either nothing, which will default to scalable
  30 # or \-[0-9]{2}, which will expand to <SIZE>x<SIZE>. For example:
  31 #
  32 #   music-player-banshee-16.png
  33 #
  34 # The <SIZE> here is -16 and will expand to 16x16 per the icon theme spec
  35 #
  36 # What follows is an example Makefile.am for icon theme installation:
  37 #
  38 # ---------------
  39 # theme=hicolor
  40 # themedir=$(datadir)/icons/$(theme)
  41 # theme_icons = \
  42 #       apps,music-player-banshee.svg \
  43 #       apps,music-player-banshee-16.png \
  44 #       apps,music-player-banshee-22.png \
  45 #       apps,music-player-banshee-24.png \
  46 #       apps,music-player-banshee-32.png
  47 #
  48 # install_icon_exec = $(top_srcdir)/build/icon-theme-installer -t $(theme) -s $(srcdir) -d "x$(DESTDIR)" -b $(themedir) -m "$(mkinstalldirs)" -x "$(INSTALL_DATA)"
  49 # install-data-local:
  50 #       $(install_icon_exec) -i $(theme_icons)
  51 #
  52 #       uninstall-hook:
  53 #               $(install_icon_exec) -u $(theme_icons)
  54 #
  55 #       MAINTAINERCLEANFILES = Makefile.in
  56 #       EXTRA_DIST = $(wildcard *.svg *.png)
  57 # ---------------
  58 #
  59 # Arguments to this program:
  60 #
  61 # -i         : Install
  62 # -u         : Uninstall
  63 # -t <theme> : Theme name (hicolor)
  64 # -b <dir>   : Theme installation dest directory [x$(DESTDIR)] - Always prefix
  65 #              this argument with x; it will be stripped but will act as a
  66 #              placeholder for zero $DESTDIRs (only set by packagers)
  67 # -d <dir>   : Theme installation directory [$(hicolordir)]
  68 # -s <dir>   : Source directory [$(srcdir)]
  69 # -m <exec>  : Command to exec for directory creation [$(mkinstalldirs)]
  70 # -x <exec>  : Command to exec for single file installation [$(INSTALL_DATA)]
  71 # <remainging> : All remainging should be category,filename pairs
