Upgrade one-true-awk to 944989bf683d30f306d8f29a3eb8c68c7c603fb4 am: 2b2ca9f3fb am: 78cb1093df am: 7be0794073 Change-Id: I31b2a71bd29660973c47448599812f37d575c9a6
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@cs.princeton.edu. Please also open an issue in the GitHub issue tracker, to make it easy to track issues. Thanks.
Pull requests are welcome. However, please create them with a request to merge into the staging
branch instead of into the master
branch. This allows us to do testing, and to make any additional edits or changes after the merge but before merging to master
.
The program itself is created by
make
which should produce a sequence of messages roughly like this:
yacc -d awkgram.y conflicts: 43 shift/reduce, 85 reduce/reduce mv y.tab.c ytab.c mv y.tab.h ytab.h cc -c ytab.c cc -c b.c cc -c main.c cc -c parse.c cc maketab.c -o maketab ./maketab >proctab.c cc -c proctab.c cc -c tran.c cc -c lib.c cc -c run.c cc -c lex.c cc 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 does not have yacc
or bison
(the GNU equivalent), you need to install one of them first.
NOTE: This version uses ANSI C (C 99), 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 compiles without change on Macintosh OS X using gcc
and the standard developer tools.
The version of malloc
that comes with some systems is sometimes astonishly slow. If awk
seems slow, you might try fixing that. More generally, turning on optimization can significantly improve awk
's speed, perhaps by 1/3 for highest levels.
