recursive bump for the dependency change
|
|
|
|
(without it the new coqide is missing things, and it seems to
specifically refer to adwaita-icon-theme by name)
Bump PKGREVISION to 1, since coqide is a default-on option.
|
|
Changes include:
- native 63-bit machine integers;
- a new sort of definitionally proof-irrelevant propositons: SProp;
- private universes for opaque polymorphic constants;
- string notations and numeral notations;
- a new simplex-based proof engine for the tactics lia, nia, lra and nra;
- new introduction patterns for SSReflect;
- a tactic to rewrite under binders: under;
- easy input of non-ASCII symbols in CoqIDE, which now uses GTK3.
and many small improvements and bugfixes.

This fixes a critical bug in the VM handling of universes, and adds
various other minor fixes and improvements.

This is a compatibility release with OCaml 4.06.0. It also contains many
bugfixes, documentation improvements and user message improvements.

Unsorted entries in PLIST files have generated a pkglint warning for at
least 12 years. Somewhat more recently, pkglint has learned to sort
PLIST files automatically. Since pkglint 5.4.23, the sorting is only
done in obvious, simple cases. These have been applied by running:
pkglint -Cnone,PLIST -Wnone,plist-sort -r -F

Includes many improvements and bugfixes (none that seem to be breaking
backwards compatibility though), see the CHANGELOG.
For packaging:
- camlp4 support removed, package now uses camlp5 exclusively
- fix for PR pkg/52651

Changes from V8.6beta1 to V8.6
==============================
Kernel
- Fixed critical bug #5248 in VM long multiplication on 32-bit
architectures. Was there only since 8.6beta1, so no stable release impacted.
Other bug fixes in universes, type class shelving,...
Changes from V8.5 to V8.6beta1
==============================
Kernel
- A new, faster state-of-the-art universe constraint checker.
Specification language
- Giving implicit arguments explicitly to a constant with multiple
choices of implicit arguments does not break any more insertion of
further maximal implicit arguments.
- Ability to put any pattern in binders, prefixed by quote, e.g.
"fun '(a,b) => ...", "λ '(a,(b,c)), ...", "Definition foo '(x,y) := ...".
It expands into a "let 'pattern := ..."
Tactics
- Flag "Bracketing Last Introduction Pattern" is now on by default.
- Flag "Regular Subst Tactic" is now on by default: it respects the
initial order of hypothesis, it contracts cycles, it unfolds no
local definitions (common source of incompatibilities, fixable by
"Unset Regular Subst Tactic").
- New flag "Refolding Reduction", now disabled by default, which turns
on refolding of constants/fixpoints (as in cbn) during the reductions
done during type inference and tactic retyping. Can be extremely
expensive. When set off, this recovers the 8.4 behaviour of unification
and type inference. Potential source of incompatibility with 8.5 developments
(the option is set on in Compat/Coq85.v).
- New flag "Shrink Abstract" that minimalizes proofs generated by the abstract
tactical w.r.t. variables appearing in the body of the proof.
On by default and deprecated. Minor source of incompatibility
for code relying on the precise arguments of abstracted proofs.
- Serious bugs are fixed in tactic "double induction" (source of
incompatibilities as soon as the inductive types have dependencies in
the type of their constructors; "double induction" remains however
deprecated).
- In introduction patterns of the form (pat1,...,patn), n should match
the exact number of hypotheses introduced (except for local definitions
for which pattern can be omitted, as in regular pattern-matching).
- Tactic scopes in Ltac like constr: and ltac: now require parentheses around
their argument.
- Every generic argument type declares a tactic scope of the form "name:(...)"
where name is the name of the argument. This generalizes the constr: and ltac:
instances.
- When in strict mode (i.e. in a Ltac definition), if the "intro" tactic is
given a free identifier, it is not bound in subsequent tactics anymore.
In order to introduce a binding, use e.g. the "fresh" primitive instead
(potential source of incompatibilities).
- New tactics is_ind, is_const, is_proj, is_constructor for use in Ltac.
- New goal selectors. Sets of goals can be selected by listing integers
ranges. Example: "1,4-7,24: tac" focuses "tac" on goals 1,4,5,6,7,24.
- For uniformity with "destruct"/"induction" and for a more natural
behavior, "injection" can now work in place by activating option
"Structural Injection". In this case, hypotheses are also put in the
context in the natural left-to-right order and the hypothesis on
which injection applies is cleared.
- Tactic "contradiction" (hence "easy") now also solve goals with
hypotheses of the form "~True" or "t<>t" (possible source of
incompatibilities because of more successes in automation, but
generally a more intuitive strategy).
- Option "Injection On Proofs" was renamed "Keep Proof Equalities". When
enabled, injection and inversion do not drop equalities between objects
in Prop. Still disabled by default.
- New tactics "notypeclasses refine" and "simple notypeclasses refine" that
disallow typeclass resolution when typechecking their argument, for use
in typeclass hints.
- Integration of LtacProf, a profiler for Ltac.
- Reduction tactics now accept more fine-grained flags: iota is now a shorthand
for the new flags match, fix and cofix.
- The ssreflect subterm selection algorithm is now accessible to tactic writers
through the ssrmatching plugin.
- When used as an argument of an ltac function, "auto" without "with"
nor "using" clause now correctly uses only the core hint database by
default.
Hints
- Revised the syntax of [Hint Cut] to follow standard notation for regexps.
- Hint Mode now accepts "!" which means that the mode matches only if the
argument's head is not an evar (it goes under applications, casts, and
scrutinees of matches and projections).
- Hints can now take an optional user-given pattern, used only by
[typeclasses eauto] with the [Filtered Unification] option on.
Typeclasses
- Many new options and new engine based on the proof monad. The
[typeclasses eauto] tactic is now a multi-goal, multi-success tactic.
See reference manual for more information. It is planned to
replace auto and eauto in the following version. The 8.5 resolution
engine is still available to help solve compatibility issues.
Program
- The "Shrink Obligations" flag now applies to all obligations, not only
those solved by the automatic tactic.
- "Shrink Obligations" is on by default and deprecated. Minor source of
incompatibility for code relying on the precise arguments of
obligations.
Notations
- "Bind Scope" can once again bind "Funclass" and "Sortclass".
General infrastructure
- New configurable warning system which can be controlled with the vernacular
command "Set Warnings", or, under coqc/coqtop, with the flag "-w". In
particular, the default is now that warnings are printed by coqc.
- In asynchronous mode, Coq is now capable of recovering from errors and
continue processing the document.
Tools
- coqc accepts a -o option to specify the output file name
- coqtop accepts --print-version to print Coq and OCaml versions in
easy to parse format
- Setting [Printing Dependent Evars Line] can be unset to disable the
computation associated with printing the "dependent evars: " line in
-emacs mode
- Removed the -verbose-compat-notations flag and the corresponding Set
Verbose Compat vernacular, since these warnings can now be silenced or
turned into errors using "-w".
XML protocol
- message format has changed, see dev/doc/changes.txt for more details.
Many bug fixes, minor changes and documentation improvements are not mentioned
here.
