The notes below are mostly of historical significance only; most -of the workarounds below were to get around restrictions/problems in earlier -versions of THINK C. The only section which still applies is Russell Finn's -description of how to make Flex generate output of type 'KAHL'. Also, 4-byte -ints must be used by any project which uses Flex output. - -If you want to recreate the project, you'll need to add the files -alloca.c and xmalloc.c in this directory. Both files are copylefted; see -the GNU General Public License for details. You will also need to recompile -both the ANSI and unix libraries to use 4 byte ints, and if you want the -files that flex creates to have 'KAHL' as the creator you'll need to apply -Russell Finn's patch. - -Notes on the THINK C version of Flex 2.3.7 -Jonas Barklund, 25-JAN-92 -Internet: jonas@csd.uu.se - -I have merged the sources for Flex version 2.3.7 with the older version -which was hacked for THINK C version 4. I have conditionalized the code -so that I think it should work with both THINK C version 4 and 5 (for -those of you who don't know: the THINK_C symbol is defined as 1 in version -4 and as 5 in version 5). I have put in some missing prototypes, so it -compiles also with "require prototypes" on. - -Most of the notes below still apply, in particular that about the MakeRes -program. - - -Notes on the THINK C version of Flex -Russell S. Finn, 19-FEB-90 -Internet: rsfinn@athena.mit.edu, rsfinn@neutron.lcs.mit.edu -CompuServe: 76377,1107 -GEnie: RSFINN - -Flex appears to be covered by a copyright notice from the University of -California, similar to the one covering Berkeley Unix; the Free Software -Foundation is not part of the picture here. So here is a version -created with THINK C 4.0, along with the source code; as with the -Bison distribution, I am including *all* of the source code I received -with the package. - -The current version (modification date January 25, 1990) has only the -bare-bones interface provided by the THINK C library routine "ccommand", -which allows the user to type a command line and to redirect the output. -Perhaps someday I may try to implement a "real" user interface; perhaps -not. - -The only modifications made to the source file are surrounded by "#ifdef -THINK_C"..."#endif"; in theory, then, these sources could be recompiled -on another system if necessary. These are the actual files modified: -alloca.c, dfa.c, flexdef.h, main.c, misc.c, scan.c, sym.c. Most of these -changes were minor, and many of them would have been unnecessary if the -original Flex source code had been written for an ANSI-compliant C compiler. -In addition, the file "macutils.c" is completely new; see the discussion -of "MakeRes" below. - -THINK C users may find it convenient to have the output text files written -by Flex be THINK C documents. To do this, create a copy of the "ANSI" -project called "ANSI-KAHL", and a copy of the file "fopen.c" called -"fopen-KAHL.c". In the copy, find the routine "setfiletype", and replace -the lines: - if (!(oflag & F_BINARY)) - pb.ioFlFndrInfo.fdType = 'TEXT'; -with the lines: - if (!(oflag & F_BINARY)) { - pb.ioFlFndrInfo.fdType = 'TEXT'; - pb.ioFlFndrInfo.fdCreator = 'KAHL'; - } -Replace "fopen.c" with the new "fopen-KAHL.c", rebuild the new project -"ANSI-KAHL", and use this project in the project file "Flex.¹" -instead of the "ANSI" project. - -** The "MakeRes" program - -The output files created by Flex contain large amounts of preinitialized -static data; the file "scan.c" contained in the Flex.¹ project is one -such file. However, the Macintosh architecture limits normal applications -to 32K of global data. In many cases (including Flex), this limit can -be surpassed by the static data generated by Flex. - -The solution I have implemented for the THINK C version of Flex is to -extract the data tables from the Flex output file, and paste them into -the file "MakeRes.c". Then, by recompiling and running the program in -the "MakeRes.¹" project (it is not necessary to create an application), -a resource file called "Flex.¹.rsrc" is created in the current directory. -The Flex output file "scan.c" has been modified to load the static data -from the resource fork of the Flex application. This is done by calling -the "load_table" function, which is defined in the file "macutils.c". - -In the application for which I needed Flex, the data tables were small -enough that I didn't need to do this. However, if your application -requires you to do this, simply follow the model of "scan.c"; the MakeRes -project and source code has been included for your use. - |
