- 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
-
- DONE: Undertake significant directory reorganization.
-
- DONE: Extensive manual cleanup:
- Use of texinfo 2.0 features
- Lots more examples
- Document posix regexps
- Document all of the above.
-
- In 3.1
- ======
- A PROCINFO array to replace /dev/pid, /dev/user, et al.
-
- Use mmap to read input files on systems that support it.
-
- Use a new or improved dfa.
-
- Integrate GNU NLS support.
-

-
- Do a reference card.
-
- ? Have strftime() pay attention to the value of ENVIRON["TZ"]

- Document use of dbm arrays
- Document NLS support
- ? Add exercises
- ? Add an error messages section to the manual
- ? A section on where gawk is bounded
