; ; File: ScriptMgrUtil.a (formerly SMgrUtil.a) ; ; Contains: Script Manager dispatcher and utility routines ; ; Written by: Joe Ternasky, September 13, 1986 ; ; Copyright: © 1986-1990, 1992 by Apple Computer, Inc., all rights reserved. ; ; Change History (most recent first): ; ; <8> 4/30/92 JSM ScriptMgrDispatch.a and ScriptMgrKeyGetSet.a now compiled ; separately for ROM builds, donŐt include them here, get rid of ; conditionals: smgrUseStdExit is always true. This file has no ; more conditionals. ; <7> 5/24/90 PKE Reorganized files: Moved ScriptUtil dispatcher and FontScript, ; Font2Script, IntlScript to new file ScriptMgrDispatch.a. This is ; included here (ptch 4) for 6.x, and included in ; ScriptMgrExtTail.a (ptch 27) for 7.0. In the latter case, we ; still have the BitBucket routines here because they are used by ; the RomanUtil dispatcher. ; <6> 5/11/90 PKE Expand dispatch table for new internal routine _AddScriptFonts. ; <5> 5/5/90 PKE Expand dispatch table for new internal routines InitScripts and ; InitKeybdMenu. ; <4> 4/10/90 PKE Use smgrSysVers, smgrROMVers, and forRom symbols instead of ; buildLevel. Deleted conditionalized definition of SysVers. Moved ; KeyScript, Get/SetEnvirons, and Get/SetScript into separate file ; ScriptMgrKeyGetSet.a which is included here. Started organizing ; for ROMification of 7.0 extensions. Add export of FontScript, ; IntlScript, Font2Script. ; <3> 3/20/90 EMT Removed unnecessary ROM85 references and oldMacTweek code. ; <2> 3/19/90 PKE Always export BitBucket and BitBucketReg. Use new feature ; conditionals smgrUseStdExit and smgrUseDispTablePtr. Deleted old ; definition: if forRom undefined, then forRom equ 0. Updated ; header to BBS format and fixed tabs. ; <1> 12/18/89 CCH Adding for the first time into BBS. Changed include 'inc.sum.a' ; to load 'StandardEqu.d'. Updated file name references. ; ; (BBS versions above, EASE versions below:) ; <2.7> 9/18/89 PKE Move KeyScript to ptch 27 so we can make a bug fix in itlk ; processing for both old and new ROMs. Change its vector here to ; be a dummy and stuff real address in ptch 27. ; <2.6> 9/17/89 PKE For 7.0, move Get/SetEnvirons and Get/SetScript to ptch 27. ; Change the vectors for these routines to be dummy vectors here; ; ptch 27 will stuff the real addresses. ; <2.5> 9/15/89 PKE Put in dummy vectors for TruncText, TruncString, ReplaceText, ; and, yes, NFindWord again (we'll allow a direct call with ; explicit specification of the break table, but the normal ; FindWord call won't use this vector). Use smLowCall60x instead ; of smLowCall for SysVers < $700, due to the fact that we can't ; conditionalize ScriptEqu.a (it is part of a dumpfile). ; <2.4> 9/5/89 PKE Delete the NFindWord vector space from the dummy address table ; created in 2.3, since we now have a different mechanism for ; getting to NFindWord. ; <2.3> 9/4/89 PKE Add dummy addresses for 7.0 routines to utilTable, to force ; allocation of space in dispatch table pointed to by ; smgrDispTable. The real routine addresses will be filled in ; later by SMgrExtTail.a (ptch 27). ; <2.2> 8/26/89 PKE Cleaned up some conditionals. ; <2.1> 8/22/89 SES Removed references to nFiles. ; <2.0> 6/30/89 PKE NEEDED FOR AURORA: Optimize table access in Get/SetEnvirons and ; Get/SetScript (from code review). ; <1.9> 6/23/89 PKE Add four verbs to GetScript/SetScript which correspond to new ; font&size information in ScriptRecord; skip definition of ; buildLevel (done in ScriptEqu.priv). ; <1.8> 6/5/89 PKE Fix comments in CommonMapping, (ROM & 7.0 only) change a bgt to ; a bpl ; <1.7> 4/26/89 PKE (ROM & 7.0 only) Change _ScriptUtil to use dispatch tables in ; RAM, accessed through pointer/limits in SmgrRecord. ; <1.6> 3/8/89 PKE Change a BEQ.S to BEQ so Big Bang builds. ; <1.5> 3/5/89 PKE Use KeyScript patch from KeyHack.a for Big Bang (as well as ROM) ; <1.4> 2/21/89 PKE Replaced with RomProj version, which already had system and Rom ; sources merged. ; (EASE ROMproj history below) ; <1.5> 2/21/89 PKE Fix up includes: always use include 'inc.sum.a'. ; <1.4> 2/14/89 PKE Updated to use MPW 3.0 final ScriptEqu.a equate names ; <1.3> 2/3/89 PKE Merged with current system sources (CCH's 01/16/1989 merge of ; 6.0.3 and 7.0 sources, done in RES.sys:smgr) ; <1.2> 11/14/88 PKE Synchronize EASE and Projector ; <1.1> 11/11/88 CCH Fixed Header. ; <1.0> 11/9/88 CCH Adding to EASE. ; (old EASE ROMproj history below) ; <1.7> 10/27/88 LDC Mods by Carl Hewitt and Brian McGhie in the process of putting ; Script Manager in ROM ; (EASE SYSproj history below) ; <1.3> 2/14/89 PKE Updated to use MPW 3.0 final ScriptEqu.a equates ; <1.2> 1/30/89 PKE Fixed end of GetEnvirons to do "move.l d0,result(a6)" for all ; systems, not just SysVers>=$700. ; <1.1> 1/16/89 CCH Merged 6.0.3 final sources into 7.0. ; <1.0> 11/16/88 CCH Added to EASE. ; (pre-EASE history below) ; 10/10/88 ldc Added code to handle itlk resource ; 10/5/88 ldc Changed scriptFlags to scriptXFlags ; ** Changes above for ROM or buildLevel 2: ** ; 6/24/88 ldc Added checking for EastAsian private verbs ; 5/19/88 ldc Added StdUnlink and StdExit ; 4/27/88 ldc Began vectorization of routines for move to ROM ; 1/27/88 med Rotate if Alternate scripts doesn't work; cleaned up flow of ; control ; 1/27/88 med CommonMapping: use faster test for non-Roman; use moveq instead ; of move.w ; 1/27/88 med ChgFont not tested properly in StdTxMeas!!! ; 1/6/88 med Added dispatch for FindScriptRun, PortionText ; 1/4/88 med Moved clear of selector high bit to under appTweak flag ; 1/4/88 med Strip high bit in bit-bucket routine ; 11/16/87 med Added dispatches ; 11/10/87 med Merged public verbs from RomanUtil into GetScript/SetScript ; 11/10/87 med Added BitBucketReg export ; 11/10/87 med Removed AISTweeks ; 11/10/87 med Fix IntlScript to force non-romans to system script, too ; 8/18/87 med Added smCharPortion verb ; 7/7/87 med Added verb entry in table for GetEnvirons of smGenFlags, ; smOverride ; 1/13/87 jdt Changed environment verb smAppScript to smLastScript. Modified ; KeyScript and added last script meta-number for quick toggling ; between two scripts. ; 12/23/86 jdt Changed name of KeyScript and fixed a deadly bug where a4 was ; used instead of a1 to find the Script Manager globals. ; 12/22/86 jdt Added the smBidirect verb to the GetEnvirons/SetEnvirons calls. ; Changed stack frames to include argument sizes. Saved space in ; GetEnvirons/SetEnvirons. Added constant for last environment ; verb. Fixed OldParamTable's Transliterate entry. Changed ; compatibility flag names. Saved space in aisTweaks tables. ; 12/3/86 jdt Added another check for old AIS script system (1.0). Additional ; code braketed by compatability flags. ; 11/25/86 jdt Added aisTweaks flags around Arabic 1.0 compatability hacks. ; Added appTweaks flags around application compatability hacks. ; 11/21/86 MED Added GetThePort macro in FontScript and IntlScript. ; 11/20/86 jdt Replaced standard equates load. ; 11/17/86 KWK Handles both old->new and new->old re-ordering of routines. ; 11/16/86 KWK Backwards compatibility is NEVER pretty. Added check for ; ScriptUtil called w/old-style selector. Added check for call to ; old AIS script system (1.0). Handles re-org of selector values. ; 10/25/86 jdt Reorganized the routine selectors. Added result and argument ; lengths to selectors. Conditional assembly directives around ; previous change. ; 10/24/86 KWK Sometimes programming isn't pretty...force 104 to Kanji so Excel ; works correctly (doesn't look for high fonds when setting up ; font dialog). ; 10/1/86 KWK Always toggle keyboard in KybdScript even if same as before. ; 9/14/86 JDT Threaded FontScript, IntlScript, and Font2Script together. ; 9/13/86 JDT Broke out ScriptUtil routines from initialization code. ;___________________________________________________________________________________________________ ; To Do (old): ; Extend number of calls handled directly by script manager. ; Remove aisTweaks for AIS 1.0 sometime in the near future. ; Remove msTweaks for Microsoft sometime in the near future. ; Remove mpwTweaks for MPW sometime in the near future. ;___________________________________________________________________________________________________ load 'StandardEqu.d' include 'ScriptPriv.a' blanks on string asis proc export StdUnlink, StdExit ; standard exit points ;<5/19/88ldc> Added StdUnlink StdExit ; ---------------------------------------------------------------------------- ; StdUnlink, StdExit ; Standard point of return for script manager routines. ; Input ; d0 := number of arguments passed to returning routine ; sp := address of jump target routine ; ---------------------------------------------------------------------------- StdUnlink unlk a6 ; unlink the stack.
