- gros commit sur ring et field: passage des arguments simplifie

2009-03-17T20:14:19+00:00

- tacinterp.ml: les arguments tactiques de Tactic Notation n'etaient
  pas evalues, laissant des variables libres (symptome: exc Not_found)
- reals: Open Local --> Local Open
- ListTactics: syntaxe des listes

Cleaning/improving the use of the "in" clause (e.g. "unfold foo in H at 4"

2009-03-16T08:18:53+00:00

now works correctly, "unfold foo at 4 in H at 3" now fails correctly,
etc.). The terminology for clauses (though I don't find the term
"clause" very intuitive after all) is mostly preserved except for
"simple_clause" which becomes a light form of "clause" instead of
being an atom of clause (what played the role of "simple_clause" is
now called "goal_location" - better names are welcome).
Main changes are in tacticals.ml and tactics.ml.

Makefile: ml dependencies of contribs are moved to .mllib files

Getting rid of the previous implementation of setoid_rewrite which was

2009-01-18T17:58:23+00:00

unplugged a long time ago.

Take advantage of natdynlink when available: almost all contribs become loadable plugins

2008-12-16T13:56:19+00:00

- Any contrib foo leads to contrib/foo/foo_plugin.cmxs (and .cma for bytecode).
- Features that were available without any Require are now loaded systematically
  when launching coqtop (see Coqtop.load_initial_plugins):
     extraction, jprover, cc, ground, dp, recdef, xml
- The other plugins are loaded when a corresponding Require is done:
     quote, ring, field, setoid_ring, omega, romega, micromega, fourier
- I experienced a crash (segfault) while turning subtac into a plugin, so this
  one stays statically linked into coqtop for now
- When the ocaml version doesn't support natdynlink, or if "-natdynlink no"
  is explicitely given to configure, coqtop is statically linked with all of
  the above code as usual. Some messages [Ignore ML file Foo_plugin] may appear.
- How should coqdep handle a "Declare ML Module "foo"" if foo is an archive
  and not a ml file ? For now, we suppose that the foo.{cmxs,cma} are at the
  same location as the .v during the build, but can be moved later in any place of
  the ml loadpath.

This is clearly an experimentation. Feedback most welcome...

Fixes and refinements regarding occurrence selection:

2008-10-26T19:22:27+00:00

- make the modifiers "value of" and "type of" for "set" working (it was not!),
- clear unselected hypotheses in the "in" clause of "induction/destruct" when
  the destructed term is a variable (experimental),
- support for generalization of hypotheses in the induction hypotheses using
  the "in" clause of "induction" (e.g. "induction n in m, H" will
  generalize over m -- would it be better to have an explicit 
  "over"/"generalizing" clause ?).
Added clause "as" to "apply in".

Fix bug #1935, reworking the reflexivity, symmetry... tactics to use

2008-09-03T14:45:58+00:00

the same typeclass method application tactic that's available to users.
Modify a bit the _red tactics to accomodate the new setup and comment
some dead code in setoid_replace. Next step is removing it completely.

Major speed and space improvements in setoid rewrite:

2008-08-27T15:48:29+00:00

- Avoid using projections for singleton classes. Divides the size
  of proofs by 2 and simplifies the typechecking as well.
- Switch to the new discrimination net implementation for classes, 
  with the current convention that all constants are unfoldable. 
  Users can add "Typeclasses Opaque" declarations make the dnet 
  discriminate more, otherwise it should be entirely
  backward-compatible.
- Fix bug introduced in r11333 in "transitivity" tactic in presence
  of coercions.
Up to 15% gains on setoid-intensive files like Ring_polynom and
Field_theory. More importantly, performance should not decrease
significantly by adding new Morphism/Setoid declarations.
