|
|
|
* Fix any 'Known bugs' as noted in the BUGS file or as
|
|
displayed by 'calc help bugs'.
|
|
|
|
* Copyleft calc and place it under a LGPL.

High priority items:
|
|
|
|
* Verify, complete or fix the 'SEE ALSO' help file sections.
|
|
|
|
* Verify, complete or fix the 'LIBRARY' help file sections.
|
|
|
|
* Verify, complete or fix the 'LIMITS' help file sections.
|
|
|
|
* Verify, complete or fix the 'SYNOPSIS' and 'TYPES' help file sections.
|
|
|
|
* Where reasonable, be sure that regress.cal tests builtin functions.
|
|
|
|
* Perform a code coverage analysis of the 'make check' action
|
|
and improve the coverage (within reason) of the regress.cal suite.
|
|
|
|
* Create a Linux rpm (Red Hat Package Manager) package for calc.
|
|
|
|
* Address, if possible and reasonable, any Calc Mis-features
|
|
as noted in the BUGS file or as displayed by 'calc help bugs'.
|
|
|
|
* The shell script that is currently constructed to display a help
|
|
file (in help.c) is a gross hack. That code should be replaced
|
|
with code that looks for the help file in the pre-defined help
|
|
directories. When the specific help file is found and opened,
|
|
then a $PAGER should be forked and execed after doing things such
|
|
as closing open file descriptors that the $PAGER does not need.
|
|
|
|
* The arg passdown to the lower level Makfiles should be reviewed
|
|
to determine which items really need to be passed down. The lower
|
|
level Makefiles should default to the shipped values.
|
|
|
|
* Consider using configure to build the calc Makefile.

Medium priority items:
|
|
|
|
* Complete the use of CONST where appropriate:
|
|
|
|
CONST is beginning to be used with read-only tables and some
|
|
function arguments. This allows certain compilers to better
|
|
optimize the code as well as alerts one to when some value
|
|
is being changed inappropriately. Use of CONST as in:
|
|
|
|
int foo(CONST int curds, char *CONST whey)
|
|
|
|
while legal C is not as useful because the caller is protected
|
|
by the fact that args are passed by value. However, the
|
|
in the following:
|
|
|
|
int bar(CONST char *fizbin, CONST HALF *data)
|
|
|
|
is useful because it calls the compiler that the string pointed
|
|
at by 'fizbin' and the HALF array pointer at by 'data' should be
|
|
treated as read-only.
|
|
|
|
* It is overkill to have nearly everything wind up in libcalc.a.
|
|
|
|
One should make available a the fundamental math operations
|
|
on ZVALUE, NUMBER and perhaps COMPLEX (without all of the
|
|
other stuff) in a separate library.
|
|
|
|
* Clean the source code and document it better.
|
|
|
|
* Add a builtin function to access the 64 bit FNV hash which
|
|
is currently being used internally in seed.c.
