This file lists future projects and enhancements for gawk. Items are listed
|
|
in roughly the order they will be done for a given release. This file is
|
|
mainly for use by the developers to help keep themselves on track, please
|
|
don't bug us too much about schedules or what all this really means.
|
|
|
|
With the 3.0 release, we are acknowledging that awk is not PERL, nor should
|
|
it become PERL. (To paraphrase Dennis Ritchie, "If you want PERL, you
|
|
know where to get it.")
|
|
|
|
The focus on the future is thus narrowed to performance and functional
|
|
enhancements, with only minor plans for significant new features.
|
|
|
|
For 3.0
|
|
=======
|
|
DONE: Move to autoconf-based configure system.
|
|
|
|
DONE: Allow RS to be a regexp.
|
|
|
|
DONE: RT variable to hold text of record terminator
|
|
|
|
DONE: split() with null string as third arg to split up strings
|
|
|
|
DONE: Analogously, setting FS="" would split the input record into
|
|
individual characters.
|
|
|
|
DONE: Generalize IGNORECASE
|
|
- any value makes it work, not just numeric non-zero
|
|
- make it apply to *all* string comparisons
|
|
|
|
DONE: Incorporate newer dfa.c and regex.c
|
|
|
|
DONE: Go to POSIX regexps
|
|
|
|
DONE: Make regex + dfa less dependant on gawk header file includes
|
|
|
|
DONE: Source code formatting cleaned up and regularized
|
|
|
|
DONE: Clean up code by isolating system-specific functions in
|
|
separate files.
|
|
|
|
DONE: General sub function:
|
|
gensub(pat, sub, global_flag[, line])
|
|
that return the substituted strings and allow \1 etc.
|
|
in the sub string.
|
|
|
|
DONE: Add AWKPATH to ENVIRON if it's not there
|
|
|
|

|
|
|

|
|
Document all of the above.
|
|
|
|
In 3.1
|
|
======
|
|
A PROCINFO array to replace /dev/pid, /dev/user, et al.
|
|
|
|
DONE: Use mmap to read input files on systems that support it.

|
|
|
Integrate GNU NLS support.
|
|
|
|
Bring out hooks for NLS support into gawk itself.
|
|
|
|
DBM storage of awk arrays. Try to allow multiple dbm packages.
|
|
|
|
Use GNU malloc.
|
|
|

Use rx instead of regex.
