Short: Enhances OpenLibrary/OpenDevice/OpenFont features Author: thor@einstein.math.tu-berlin.de (Thomas Richter) Uploader: thor einstein math tu-berlin de (Thomas Richter) Type: util/sys Version: 1.04 Architecture: m68k-amigaos This is a patch to the OpenLibrary/OpenDevice/OpenDiskFont call. When installed... o) OpenLibrary will also look in the "LIBS" and "CLASSES" subdirectories of the current directory, and in "PROGDIR:", "PROGDIR:Libs" and "PROGDIR:Classes". o) OpenDevice will try to find devices in "DEVS", "PROGDIR:" and "PROGDIR:DEVS" o) OpenDiskFont will load fonts from the "FONTS", "PROGDIR:" and "PROGDIR:FONTS" directory. Thus, BetterOpenLibs supports the use of private libraries, devices and fonts for a program, stored in the directory of the program instead in the global drawers. No need to mess up your global library/ devices or fonts dirs with tons of private and otherwise useless stuff. ____________________________________________________________________________ Changes made to 1.04: Added local devices and fonts support. Rewrote parts of the patch. It uses now more stack, but is a "cleaner" solution compared to the previous versions. The diskfont.library is not permanenty locked in the memory, but only patched when needed. ____________________________________________________________________________ There's already one patch (the OpenLibEnhancer) on the net that does this work, but after testing for a while I found that it does not work well with some software, and after looking into the code I found that this utility is quite broken (the stack is used wrongly, plus some more). So I decided to fill this gap and write my own... and the problems I had before were gone.... Installation: Copy to your C: drawer. Invokation: BetterOpenLibs NOLIBS/S,NOCLASSES/S,NOPROGDIR/S NOPROGDIRLIBS/S,NOPROGDIRCLASSES/S NODEVS/S,NOPROGDIRD/S,NOPROGDIRDEVS/S NOFONTS/S,NOPROGDIRF/S,NOPROGDIRFONTS/S: library-related flags: NOLIBS: Do not look into the libs directory of the current dir. NOCLASSES: Same, but ignore "Classes" NOPROGDIR: Do not search in "PROGDIR:" NOPROGDIRLIBS: Do not search in "PROGDIR:Libs" NOPROGDIRCLASSES: Do not search in "PROGDIR:Classes" device-related flags: NODEVS: Do not scan "Devs" NOPROGDIRD: Do not scan "PROGDIR:" NOPROGDIRDEVS: Do not scan "PROGDIR:Devs" font-related flags: NOFONTS: Do not look in "Fonts" NOPROGDIRF: Do not look in "PROGDIR:" NOPROGDIRFONTS: Do not look in "PROGDIR:Fonts" Especially, the "PROGDIR:" and its subdirectories are not searched if the invoking process has no home directory, and the enhanced features are disabled if called from a task. (Since they don't make sense in this case). No PROGDIR: assign is made. Be careful with the fonts-patch: The AvailFonts() function of the diskfont.library WON'T tell you about the additional fonts in the directories LOCAL to the program, it returns ONLY information about fonts available for all programs - so all fonts in the FONTS: drawer. No implicit "ASSIGN ADD" is performed! The font patch WILL NOT help for programs that load or scan fonts by other methods than using the diskfont.library. The patch mechanism used for the diskfont.library is a bit tricky, but explicitly compatible to the mechanism esablished with MY version of "SaferPatches". I can't give any guarantee that it works with "dumber" implementations of the "SaferPatches" program. In cases of doubt, try my program... ____________________________________________________________________________ The THOR-Software Licence This License applies to the computer programs known as "BetterOpenLibs".
