Many changes, among them:
- Many bugs have been fixed (cf coq-bugs web page)
- changed parsing precedence of let/in and fun constructions of Ltac:
let x := t in e1; e2 is now parsed as let x := t in (e1;e2).
- New primitive "external" for communication with tool external to Coq.
- Omega now handles arbitrary precision integers.
- Haskell extraction: types of functions are now printed, better
unsafeCoerce mechanism, both for hugs and ghc.
- Scheme extraction improved, see http://www.pps.jussieu.fr/~letouzey/scheme.
- New notation "exists! x:A, P" for unique existence.
- New library on String and Ascii characters (contributed by L. Thery).
- New library FSets+FMaps of finite sets and maps.
- New library QArith on rational numbers.
- Few improvements in ZArith potentially exceptionally breaking the
compatibility (useless hypothesys of Zgt_square_simpl and
Zlt_square_simpl removed; fixed names mentioning letter O instead of
digit 0; weaken premises in Z_lt_induction).
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).
Changelog:
- Coq sources made compatible with ocaml 3.09.0 and lablgtk 2.6.0.
- The search depth argument of auto can be parameterised in the Ltac language
- Added entry constr_may_eval for tactic extensions (new syntax)
- A couple of lemmas of ZArith were renamed: O -> 0
- many bugfixes, for extraction, Ltac, tactics...
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
with prior art (e.g. lang/twelf).
Coq is a Proof Assistant for a Logical Framework known as the
Calculus of Inductive Constructions. It allows the interactive
construction of formal proofs, and also the manipulation of
functional programs consistently with their specifications.
