* Add a test for german case folding.
* Add a function to copy a string with a string with a larger allocation
(to be used by the case folding routines)
* Add printf attributes to the printf-like functions and fix one format
warning
* Cleanup the tempfree macro
* make more functions static
* rename fp to frp (FRame Pointer) to avoid shadowing with fp (File Pointer).
* add more const
* fix indent in UPLUS case
* add locale-aware case folding
* make nfiles size_t
* fix bugs in file closing:
- compare fclose to EOF and pclose to -1
- use nfiles instead of FOPEN_MAX in closeall
- don't close files we did not open (0,1,2) fpurge/fflush instead
* - use NUL instead of 0 for char comparisons
- add ISWS() macro
- use continue; instead of ;
* Check for existance of the german locale before using it.
* Add missing parentheses, thanks Arnold.

The One True Awk
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).

Distribution and Reporting Problems
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.
Submitting Pull Requests
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.
Building
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.
