|
|
Changes:
A number of minor changes.
Fixes and improvements to the Mathomatic Command Reference.
Upgraded clear and set commands to accept more than one argument.
Gave real and imaginary commands a useful argument.
Fixed a sloppiness in command line parsing in function get_range().
Code cleanup.
|
|
Changes:
Improved matho-primes by making primes buffer variable size.
Added "set factor_integers" option.
Removed "simplify poly" option, it was rarely useful.
Code cleanup, commenting, and speed optimization.
Improved simplification, added the fixed problem ("tests/linear.in") to the tests.

RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
