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.
|
|
|
|

|
|
individual characters.
