This is the version of awk described in "The AWK Programming Language",
|
|
by Al Aho, Brian Kernighan, and Peter Weinberger
|
|
(Addison-Wesley, 1988, ISBN 0-201-07981-X).
|
|
|
|
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.
