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 developer(s) to help keep themselves on track, please
|
|
don't bug us too much about schedules or what all this really means.

========
|
|
x Move to autoconf-based configure system.
|
|
|
|
x Research awk `fflush' function.
|
|
|

x Split() with null string as third arg to split up strings
|

|
|
x Analogously, setting FS="" would split the input record into individual
|
|
characters.
|
|
|
|
x Clean up code by isolating system-specific functions in separate files.
|
|
|
|
Undertake significant directory reorganization.
|
|
|

Lots more examples

Document all of the above.

|
|
that return the substituted strings and allow \1 etc. in the sub

For 2.20 or later:
|
|
==================
|
|
Add variables similar to C's __FILE__ and __LINE__ for better diagnostics
|
|
