- 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.
-
- (An `x' indicates that some progress has been made, but that the feature is
- not complete yet.)
-
- For 2.16
- ========
- x Move to autoconf-based configure system.
-
- x Research awk `fflush' function.
-
- x Generalize IGNORECASE

- =======
- x Allow RS to be a regexp.
-
- RT variable to hold text of record terminator
-
- RECLEN variable for fixed length records
-
- Feedback alloca.s changes to FSF
-
- 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.
-
- x Extensive manual cleanup:
- Use of texinfo 2.0 features
- Lots more examples
- Document all of the above.
-
- x Go to POSIX regexps
-
- Make regex + dfa less dependant on gawk header file includes
-
- Additional manual features:
- Document posix regexps
- Document use of dbm arrays
- ? Add an error messages section to the manual
- ? A section on where gawk is bounded
- regex
- i/o
- sun fp conversions
-
- For 2.18
- ========
- DBM storage of awk arrays. Try to allow multiple dbm packages
-
- General sub functions:
- edit(line, pat, sub) and gedit(line, pat, sub)
- that return the substituted strings and allow \1 etc. in the sub
- string.
-
- ? Have strftime() pay attention to the value of ENVIRON["TZ"]
-
- For 2.19
- ========
- Add chdir and stat built-in functions.
-
- Add function pointers as valid variable types.
-
- Add an `ftw' built-in function that takes a function pointer.
-
- Do an optimization pass over parse tree?
-
- For 2.20 or later:
- ==================
- Add variables similar to C's __FILE__ and __LINE__ for better diagnostics
- from within awk programs.
-
- Add an explicit concatenation operator and assignment version.
-
- ? Add a switch statement
-
- Add the ability to seek on an open file and retrieve the current file position.
-
- Add lint checking everywhere, including check for use of builtin vars.
- only in new awk.
-
- "restart" keyword
-
- Add |&
-
- Make awk '/foo/' files... run at egrep speeds
-
- Do a reference card
-
- Allow OFMT and CONVFMT to be other than a floating point format.

-
- Make it faster and smaller.
-
