http://plan9.bell-labs.com/who/bwk/ This is version 970821 without modification for GNO/ME compatibility. It's being included in the repository to assist in importing future versions of awk from Bell Labs. ---------------------------------------------------------------------- Added Files: awk/FIXES awk/README awk/awk.1 awk/awk.h awk/awkgram.y awk/b.c awk/lex.c awk/lib.c awk/main.c awk/makefile awk/maketab.c awk/missing95.c awk/parse.c awk/proto.h awk/run.c awk/tran.c awk/ytab.c awk/ytab.h awk/ytabc.bak awk/ytabh.bak ---------------------------------------------------------------------- -- Dave Tribby |

Changes, mostly bug fixes and occasional enhancements, are listed in FIXES. If you distribute this code further, please please please distribute FIXES with it. If you find errors, please report them to bwk@bell-labs.com. Thanks. The program itself is created by make which should produce a sequence of messages roughly like this: yacc -d awkgram.y conflicts: 42 shift/reduce, 83 reduce/reduce mv y.tab.c ytab.c mv y.tab.h ytab.h cc -O -c ytab.c cc -O -c b.c cc -O -c main.c cc -O -c parse.c cc -O maketab.c -o maketab ./maketab >proctab.c cc -O -c proctab.c cc -O -c tran.c cc -O -c lib.c cc -O -c run.c cc -O -c lex.c cc -O ytab.o b.o main.o parse.o proctab.o tran.o lib.o run.o lex.o -lm This produces an executable a.out; you will eventually want to move this to some place like /usr/bin/awk. If your system is does not have yacc or bison (the GNU equivalent), you must compile the pieces manually. We have included yacc output in ytab.c and ytab.h, and backup copies in case you overwrite them. NOTE: This version uses ANSI C, as you should also. We have compiled this without any changes using gcc -Wall and/or local C compilers on a variety of systems, but new systems or compilers may raise some new complaint; reports of difficulties are welcome. This also compiles with Visual C++ 4.1 on Windows 95 and presumably Windows NT, *if* you provide versions of popen and pclose. The file missing95.c contains do-nothing versions that can be used to get started with. It is too much trouble to figure out how to make these work for real. The version of malloc that comes with some systems is sometimes astonishly slow. If awk seems slow, you might try fixing that.
