2006-10-15 Kevin Cozens <kcozens@cvs.gnome.org> With this commit we finally say goodbye to SIOD. This large set of changes updates the Script-Fu plug-in to use the TinyScheme Scheme interpreter. These changes originated with changes originally made to Script-Fu which created Tiny-Fu (aka. the gimp-tiny-fu module). * plug-ins/script-fu/Makefile.am * plug-ins/script-fu/script-fu-console.c * plug-ins/script-fu/script-fu-interface.c * plug-ins/script-fu/script-fu-scripts.c * plug-ins/script-fu/script-fu-scripts.h * plug-ins/script-fu/script-fu-server.c * plug-ins/script-fu/script-fu-text-console.c * plug-ins/script-fu/script-fu.c: Updated with the changes made to these files as part of the work on the Tiny-Fu project. * plug-ins/script-fu/scheme-wrapper.c * plug-ins/script-fu/scheme-wrapper.h: Renamed from siod-wrapper.[ch] and updated based on differences to ts-wrapper.[ch] from gimp-tiny-fu. * plug-ins/script-fu/ftx/* * plug-ins/script-fu/re/* * plug-ins/script-fu/tinyscheme/* * plug-ins/script-fu/scripts/script-fu.init * plug-ins/script-fu/scripts/script-fu-compat.init * plug-ins/script-fu/scripts/contactsheet.scm * plug-ins/script-fu/scripts/script-fu-set-cmap.scm * plug-ins/script-fu/scripts/script-fu-util-setpt.scm * plug-ins/script-fu/scripts/ts-helloworld.scm: Added all of these files and directories from Tiny-Fu. Updated the Makefile.am files of ftx, re, and tinyscheme now they are in the GIMP source tree. * plug-ins/script-fu/scripts/*.scm: All scripts have been updated as needed to ensure they will work with the TinyScheme interpreter. Most of the files have been reformatted making it easier to see the syntax of Scheme and making them easier to read. * plug-ins/script-fu/scripts/Makefile.am: Updated script file lists. * plug-ins/script-fu/siod-wrapper.c * plug-ins/script-fu/siod-wrapper.h * plug-ins/script-fu/siod/*: Removed obsolete files. * configure.in: Updated list of files in AC_CONFIG_FILES. Changed --disable-script-fu to --without-script-fu which it should have been when originally added. * INSTALL: Updated to show change to --without-script-fu.
