adding a new grammar entry for clauses
|
|
|
|
|
|
|
|
| |
With ocaml 4.01, the 'unused open' warning also checks the mli :-)
Beware: some open are reported as useless when compiling with camlp5,
but are necessary for compatibility with camlp4. These open are now
marked with a comment.

containing opaque grammar objects, it now contains a string representing
the entry. In order to recover the entry from the string, the former must
have been created with [Pcoq.create_generic_entry] or similar. This is
guaranteed for entries generated by ARGUMENT EXTEND, and must be done by
hand otherwise.
Some plugins were fixed accordingly.

refine tactic, which now uses plain glob_constr's. Now there
is no real need to depend on goal when interpreting genargs.
Possible minor incompatibilities:
1. The interpretation of glob_constr to constr is now done by
Goal.constr_of_raw, which may be slightly dumbier than the dedicated
Tacinterp.interp_open_constr which tries harder. Stdlib and test-suite
do go through, though.
2. I had to change the parsing level of wit_glob in Extraargs
from lconstr to constr. It may break ML notations using glob, but
as they are only used inside Coq code and all well-parenthezised,
it should be OK.

Ok, this is merely a matter of taste, but up to now the usage
in Coq is rather to use capital letters instead of _ in the
names of inner modules.

kernel on CAMLP4/5 structures, and consequently should also erase
such structures from vo files.
This modification requires some code duplication, mainly while
reimplementing our own location data type. This is chiefly visible
in the ml4 files, where CAMLP4/5 locations must be manually converted
to our locations with an explicit (!@) cast operator.

Meanwhile, a simplified interface is provided in loc.mli.
This also permits to put Pp in Clib, because it does not depend on
CAMLP4/5 anymore.

Util only depends on Ocaml stdlib and Utf8 tables.
Generic pretty printing and loc functions are in Pp.
Generic errors are in Errors.
+ Training white-spaces, useless open, prlist copies random erasure.
Too many "open Errors" on the contrary.

In particular, the unused lib/tlm.ml and lib/gset.ml are removed
In addition, to simplify code, Libobject.record_object returning only the
('a->obj) function, which is enough almost all the time.
Use Libobject.record_object_full if you really need also the (obj->'a).

- Added support for recursive notations with binders
- Added support for arbitrary large iterators in recursive notations
- More checks on the use of variables and improved error messages
- Do side-effects in metasyntax only when sure that everything is ok
- Documentation
Note: it seems there were a small bug in match_alist (instances obtained
from matching the first copy of iterator were not propagated).

The choice between camlp4/5 is done during configure with flags
-usecamlp5 (default for the moment) vs. -usecamlp4.
Currently, to have a full camlp4 compatibility, you need to change
all "EXTEND" and "GEXTEND Gram" into "EXTEND Gram", and change "EOI"
into "`EOI" in grammar entries. I've a sed script that does that
(actually the converse), but I prefer to re-think it and check a few
things before branching this sed into the build mechanism.
lib/compat.ml4 is heavily used to hide incompatibilities between camlp4/5
and try to propose a common interface (cf LexerSig / GrammarSig).
A few incompatible quotations have been turned into underlying code
manually, in order to make the IFDEF CAMLP5 THEN ... ELSE ... END
parsable by both camlp4 and 5. See in particular the fate of
<:str_item< declare ... end >>
Stdpp isn't used anymore, but rather Ploc (hidden behind local module Loc).
This forces to use camlp5 > 5.01.

Cf tok.ml, token isn't anymore string*string where first
string encodes the kind of the token, but rather a nice
sum type. Unfortunately, string*string (a.k.a Plexing.pattern)
is still used in some places of Camlp5, so there's a few
conversions back and forth. But the penalty should be quite low,
and having nicer tokens helps in the forthcoming integration
of support for camlp4 post 3.10

- Many of them were broken, some of them after Pierre B's rework
of mli for ocamldoc, but not only (many bad annotation, many files
with no svn property about Id, etc)
- Useless for those of us that work with git-svn (and a fortiori
in a forthcoming git-only setting)
- Even in svn, they seem to be of little interest

dev/ocamlweb-doc has been erased. I hope no one still use the
"new-parse" it generate.
In dev/,
make html will generate in dev/html/ "clickable version of mlis". (as
the caml standard library)
make coq.pdf will generate nearly the same awfull stuff that coq.ps was.
make {kernel,lib,parsing,..}.{dot,png} will do the dependancy graph of
the given directory.
ocamldoc comment syntax is here :
http://caml.inria.fr/pub/docs/manual-ocaml/manual029.html
The possibility to put graphs in pdf/html seems to be lost.

This is a fairly large commit (around 140 files and 7000 lines of code
impacted), it will cause some troubles for sure (I've listed the know
regressions below, there is bound to be more).
At this state of developpement it brings few features to the user, as
the old tactics were
ported with no change. Changes are on the side of the developer mostly.
Here comes a list of the major changes. I will stay brief, but the code
is hopefully well documented so that it is reasonably easy to infer the
details from it.
Feature developer-side:
* Primitives for a "real" refine tactic (generating a goal for each
evar).
* Abstract type of tactics, goals and proofs
* Tactics can act on several goals (formally all the focused goals). An
interesting consequence of this is that the tactical (. ; [ . | ... ])
can be separated in two
tacticals (. ; .) and ( [ . | ... ] ) (although there is a conflict for
this particular syntax). We can also imagine a tactic to reorder the
goals.
* Possibility for a tactic to pass a value to following tactics (a
typical example is
an intro function which tells the following tactics which name it
introduced).
* backtracking primitives for tactics (it is now possible to implement a
tactical '+'
with (a+b);c equivalent to (a;c+b;c) (itself equivalent to
(a;c||b;c)). This is a valuable
tool to implement tactics like "auto" without nowing of the
implementation of tactics.
* A notion of proof modes, which allows to dynamically change the parser
for tactics. It is controlled at user level with the keywords Set
Default Proof Mode (this is the proof mode which is loaded at the start
of each proof) and Proof Mode (switches the proof mode of the current
proof) to control them.
* A new primitive Evd.fold_undefined which operates like an Evd.fold,
except it only goes through the evars whose body is Evar_empty. This is
a common operation throughout the code,
some of the fold-and-test-if-empty occurences have been replaced by
fold_undefined. For now,
it is only implemented as a fold-and-test, but we expect to have some
optimisations coming some day, as there can be a lot of evars in an
evar_map with this new implementation (I've observed a couple of
thousands), whereas there are rarely more than a dozen undefined ones.
Folding being a linear operation, this might result in a significant
speed-up.
* The declarative mode has been moved into the plugins. This is made
possible by the proof mode feature. I tried to document it so that it
can serve as a tutorial for a tactic mode plugin.
Features user-side:
* Unfocus does not go back to the root of the proof if several Focus-s
have been performed.
It only goes back to the point where it was last focused.
* experimental (non-documented) support of keywords
BeginSubproof/EndSubproof:
BeginSubproof focuses on first goal, one can unfocus only with
EndSubproof, and only
if the proof is completed for that goal.
* experimental (non-documented) support for bullets ('+', '-' and '*')
they act as hierarchical BeginSubproof/EndSubproof:
First time one uses '+' (for instance) it focuses on first goal, when
the subproof is
completed, one can use '+' again which unfocuses and focuses on next
first goal.
Meanwhile, one cas use '*' (for instance) to focus more deeply.
Known regressions:
* The xml plugin had some functions related to proof trees. As the
structure of proof changed significantly, they do not work anymore.
* I do not know how to implement info or show script in this new engine.
Actually I don't even know what they were suppose to actually mean in
earlier versions either. I wager they would require some calm thinking
before going back to work.
* Declarative mode not entirely working (in particular proofs by
induction need to be restored).
* A bug in the inversion tactic (observed in some contributions)
* A bug in Program (observed in some contributions)
* Minor change in the 'old' type of tactics causing some contributions
to fail.
* Compilation time takes about 10-15% longer for unknown reasons (I
suspect it might be linked to the fact that I don't perform any
reduction at QED-s, and also to some linear operations on evar_map-s
(see Evd.fold_undefined above)).

- make links to section variables working (used qualified names for
disambiguation and fixed the place in intern_var where to dump them)
(wish #2277)
- mapping of physical to logical paths now follows coq (see bug #2274)
(incidentally, it was also incorrectly seeing foobar.v as a in directory foo)
- added links for notations
- added new category "other" for indexing entries not starting with latin letter
(e.g. notations or non-latin identifiers which was otherwise broken)
- protected non-notation strings (from String.v) from utf8 symbol interpretation
- incidentally quoted parseable _ in notations to avoid confusion with
placeholder in the "_ + _" form of notation
- improved several "Sys_error" error messages
- fixed old bug about second dot of ".." being interpreted as regular dot
- removed obsolete lexer in index.mll (and renamed index.mll to index.ml)
- added a test-suite file for testing various features of coqdoc
Things that still do not work:
- when a notation is redefined several times in the same scope, only
the link to the first definition works
- if chars and symbols are not separated in advance, idents
that immediately follow symbols are not detected
(e.g. as in {True}+{True} where coqdoc sees a symbol "+{True}")
- parentheses, curly brackets and semi-colon not linked in notations
Things that can probably be improved:
- all notations are indexed in the same category "other"; can we do better?
- all non-latin identifiers (e.g. Greek letters) are also indexed in the
same "other" category; can we do better?
- globalization data for notations could be compacted (currently there is one
line per each proper location covered by the notation)

typeclasses parsing code).

- Correction divers messages d'erreur
- lorsque rien à réécrire dans une hyp,
- lorsqu'une variable ltac n'est pas liée,
- correction anomalie en présence de ?id dans le "as" de induction,
- correction mauvais env dans message d'erreur de unify_0.
- Diverses extensions et améliorations
- "specialize" :
- extension au cas (fun x1 ... xn => H u1 ... un),
- renommage au même endroit.
- "assert" et "pose proof" peuvent réutiliser la même hyp comme "specialize".
- "induction"
- intro des IH toujours au sommet même si induction sur var quantifiée,
- ajout d'un hack pour la reconnaissance de schémas inductifs comme
N_ind_double mais il reste du boulot pour reconnaître (et/ou
réordonner) les composantes d'un schéma dont les hypothèses ne sont pas
dans l'ordre standard,
- vérification de longueur et éventuelle complétion des
intropatterns dans le cas de sous-patterns destructifs dans induction
(par exemple "destruct n as [|[|]]" sur "forall n, n=0" ne mettait pas
le n dans le contexte),
- localisation des erreurs d'intropattern,
- ajout d'un pattern optionnel après "as" pour forcer une égalité et la
nommer (*).
- "apply" accepte plusieurs arguments séparés par des virgules (*).
- Plus de robustesse pour clear en présence d'evars.
- Amélioration affichage TacFun dans Print Ltac.
- Vieux pb espace en trop en tête d'affichage des tactiques EXTEND résolu
(incidemment, ça remodifie une nouvelle fois le test output Fixpoint.v !).
- Fusion VTactic/VFun dans l'espoir.
- Mise en place d'un système de trace de la pile des appels Ltac (tout en
préservant certains aspects de la récursivité terminale - cf bug #468).
- Tactiques primitives
- ajout de "move before" dans les tactiques primitives et ajout des
syntaxes move before et move dependent au niveau utilisateur (*),
- internal_cut peuvent faire du remplacement de nom d'hypothèse existant,
- suppression de Intro_replacing et du code sous-traitant
- Nettoyage
- Suppression cible et fichiers minicoq non portés depuis longtemps.
(*) Extensions de syntaxe qu'il pourrait être opportun de discuter

classes, and simplify the implementation.
- Experimental syntax {{ cl : Class args }} and (( cl : Class args ))
which respectively make cl an implicit or explicit argument ({{ }} is
equivalent to [ ]). Could be extended to any type of binder, eg.
[Definition flip ((R : relation carrier)) : relation carrier := ...].
The idea behind double brackets is to distinguish macro-binders which
perform implicit generalization from regular binders. It could also save
[ ] for other uses.
- Fix bug #1901 about {} binders in records.

- Now [ id : Class foo ] makes id an explicit argument,
and [ Class foo ] is equivalent to [ {someid} : Class foo ].
This makes declarations such as "Class Ord [ eq : Eq a ]" have
sensible implicit args.
- Better handling of {} in class and record declarations, refactorize
code for declaring structures and classes.
- Fix merging of implicit arguments information on section closing.

binders.
- Change syntax of type class instances to better match the usual syntax of
lemmas/definitions with name first, then arguments ":" instance.
Update theories/Classes accordingly.
- Correct globalization of tactic references when doing Ltac :=/::=, update
documentation.
- Remove the not so useful "(x &)" and "{{x}}" syntaxes from
Program.Utils, and subset_scope as well.
