* A fine-grain control of inlining at functor application via priority levelsGravatar letouzey2011-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As said in CHANGES: << The inlining done during application of functors can now be controlled more precisely. In addition to the "!F G" syntax preventing any inlining, we can now use a priority level to select parameters to inline : "<30>F G" means "only inline in F the parameters whose levels are <= 30". The level of a parameter can be fixed by "Parameter Inline(30) foo". When levels aren't given, the default value is 100. One can also use the flag "Set Inline Level ..." to set a level. >> Nota : the syntax "Parameter Inline(30) foo" is equivalent to "Set Inline Level 30. Parameter Inline foo.", and "Include <30>F G" is equivalent to "Set Inline Level 30. Include F G." For instance, in ZBinary, eq is @Logic.eq and should rather be inlined, while in BigZ, eq is (fun x y => [x]=[y]) and should rather not be inlined. We could achieve this behavior by setting a level such as 30 to the parameter eq, and then tweaking the current level when applying functors. This idea of levels might be too restrictive, we'll see, but at least the implementation of this change was quite simple. There might be situation where parameters cannot be linearly ordered according to their "inlinablility". For these cases, we would need to mention names to inline or not at a functor application, and this is a bit more tricky (and might be a pain to use if there are many names). No documentation for the moment, since this feature is experimental and might still evolve. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13807 85f007b7-540e-0410-9357-904b9bb8a0f7
* Remove the "Boxed" syntaxes and the const_entry_boxed fieldGravatar letouzey2011-01-28
| | | | | | | | | | | | | | | | According to B. Gregoire, this stuff is obsolete. Fine control on when to launch the VM in conversion problems is now provided by VMcast. We were already almost never boxing definitions anymore in stdlib files. "(Un)Boxed Definition foo" will now trigger a parsing error, same with Fixpoint. The option "(Un)Set Boxed Definitions" aren't there anymore, but tolerated (as no-ops), since unknown options raise a warning instead of an error by default. Some more cleaning could be done in the vm. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13806 85f007b7-540e-0410-9357-904b9bb8a0f7

* ARGUMENT EXTEND: forbid TYPED simultaneously with {RAW,GLOB}_TYPEDGravatar glondu2010-12-25
| | | | | | | | | | | | Rationale: the expansion ignores the TYPED clause when {RAW,GLOB}_TYPED are given. Indeed, in this case, the final type is a consequence of either "INTERPRETED BY" (if given), or the default one based on GLOB_TYPED. This avoids the pitfall of the "raw" argument extension, where the TYPED clause was unused and totally misleading. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13760 85f007b7-540e-0410-9357-904b9bb8a0f7
* Avoid "open {Pcoq,Extrawit}" clauses in expansion of EXTEND commandsGravatar glondu2010-12-25
| | | | | | | | | | It is quite nasty to insert those open in places where they can change the semantics of surrounding code... instead, prefer using fully-qualified names in generated code when possible. For ExtraArgType, simulate a "open Extrawit in ..." (which does exist primitively in OCaml >= 3.12) with the usual encoding. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13759 85f007b7-540e-0410-9357-904b9bb8a0f7

* Change of nomenclature: rawconstr -> glob_constrGravatar glondu2010-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a discrepancy of the notions "raw" and "globalized" between constrs and tactics, and some confusion of the notions in e.g. genarg.mli (see all globwit_* there). This commit is a first step towards unification of terminology between constrs and tactics. Changes in module names will be done separately. In extraargs.ml4, the "ARGUMENT EXTEND raw" and related stuff, even affected by this change, has not been touched and highlights another confusion in "ARGUMENT EXTEND" in general that will be addressed later. The funind plugin doesn't respect the same naming conventions as the rest, so leave some "raw" there for now... they will be addressed later.

* Remove VernacGoGravatar glondu2010-10-06
| | | | | | | | | | | | | | | | I agree with Arnaud on this one... Archeology: I could trace it back to r133 (in 1999!), and it was adapted to many big changes, including change of parsing (r2722, in 2002). Maybe it was used by Centaur or something similar once... The only relevant occurrences of "Go" in SVN history (since initial commit in 1999) is that it "semble peu robuste aux erreurs", without a clear specification of what it is supposed to do... Looks like an interesting feature, though, but needs complete rethinking (and documentation) with the new engine. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13506 85f007b7-540e-0410-9357-904b9bb8a0f7

* Making display of various informations about constants more modular:Gravatar herbelin2010-10-03
| | | | | | | | | | | | | | - use list of non-newline-ended phrases instead of newline-separated texts because newline-separated texts does not support well being put in boxes (e.g. ''v 2 (str"a" ++ fnl()) ++ str"b" ++ fnl()'' prints "b" at indentation 2 while to get the expected output, one would have needed to have the fnl outside the box as in ''v 2 (str"a") ++ fnl() ++ str"b" ++ fnl()'' - also reason over lists of explicitly non-empty lines instead of checking for "mt" lines to skip The reason of this is to permit nesting of printing infos. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13482 85f007b7-540e-0410-9357-904b9bb8a0f7

* Simplify tactic(_)-bound arguments in TACTIC EXTEND rulesGravatar glondu2010-09-30
| | | | | | | | | | | | | | Arguments bound with tactic(_) in TACTIC EXTEND rules are now of type glob_tactic_expr, instead of glob_tactic_expr * tactic. Only the first component is kept, the second one can be obtained with Tacinterp.eval_tactic. Rationale: these declare parsing rules, and eval_tactic is a semantic action, and therefore should be done in the rule body instead. Moreover, having the glob_tactic_expr and its evaluation captured by these rules was quite confusing IMHO. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13480 85f007b7-540e-0410-9357-904b9bb8a0f7

* Finish adding out-of-the-box support for camlp4Gravatar letouzey2010-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | If you want to try, it should be now as simple as: make clean && ./configure -local -usecamlp4 && make For the moment, the default stays camlp5, hence ./configure -usecamlp5 and ./configure are equivalent. Thanks to a suggestion by N. Pouillard, the remaining incompatibilities are now handled via some token filtering in camlp4. See compat5*.mlp. Morally, these files should be named .ml4, but I prefer having them not in $(...ML4) variables, it might confuse the Makefile... The empty compat5*.ml are used to build empty .cmo for making camlp5 happy. For camlp4, - tools/compat5.cmo changes GEXTEND into EXTEND. Safe, always loaded - tools/compat5b.cmo changes EXTEND into EXTEND Gram. Interact badly with syntax such that VERNAC EXTEND, we only load it for a few files via camlp4deps TODO: check that my quick adaptation of camlp5-specific code in tactics/extratactics.ml4 is ok.

* Added support for Ltac-matching terms with variables bound in the patternGravatar herbelin2010-06-06
| | | | | | | | | | | | | | | | | | - Instances found by matching.ml now collect the set of bound variables they possibly depend on in the pattern (see type Pattern.extended_patvar_map); the variables names are canonically ordered so that non-linear matching takes actual names into account. - Removed typing of matching constr instances in advance (in tacinterp.ml) and did it only at use time (in pretyping.ml). Drawback is that we may have to re-type several times the same term but it is necessary for considering terms with locally bound variables of which we do not keep the type (and if even we had kept the type, we would have to adjust the indices to the actual context the term occurs). - A bit of documentation of pattern.mli, matching.mli and pretyping.mli. - Incidentally add env while printing idtac messages. It seems more correct and I hope I did not break some intended existing behavior. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13080 85f007b7-540e-0410-9357-904b9bb8a0f7

* Add (almost) compatibility with camlp4, without breaking support for camlp5Gravatar letouzey2010-05-19
| | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13019 85f007b7-540e-0410-9357-904b9bb8a0f7

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 git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13018 85f007b7-540e-0410-9357-904b9bb8a0f7

* Fail: a way to check that a command is refused without blocking a scriptGravatar letouzey2010-04-30
| | | | | | | | | | | | | | | | | | | | | | | "Fail cmd" is similar to "Time cmd", but instead of printing the execution time, it reverse the exit status of cmd. "Fail cmd" is successful iff cmd has ended with an error. This was, we can demonstrate erroneous commands in a script for pedagogical or testing purpose without having to comment it in order to play the rest of the script in coqide/PG. Coq < Fail Foo. The command has indeed failed with message: => Error: Unknown command of the non proof-editing mode. Coq < Fail Check Prop. Prop : Type Error: The command has not failed ! Two more remarks: - Fail doesn't catch anomalies. - Yes it it possible to write things like Fail Fail ... :-) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12981 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | - 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 git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12972 85f007b7-540e-0410-9357-904b9bb8a0f7
