* A tatical "timeout <n> <tac>" that fails if <tac> hasn't finished in <n> secondsGravatar letouzey2011-03-18
| | | | | | | | | | | | | | Note: even if this new tactical can be quite handy during the development phase, (for instance to bound the time allocated to some search tactics), please be aware of its main drawback: with it, scripts are no longer machine-independant, something that works on a quick machine may fail on a slow one. The converse is even possible if you combine this "timeout" with other tactic combinators. We strongly advise to not leave any "timeout" in the final version of a development. In addition, this feature won't probably work on native win32, since Unix.alarm isn't implemented. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13917 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | After r13717, we concentrate on undefined evars. But doing so too naively was breaking Class_tactics.split_evars, since defined evars may point to undefined ones.

* 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

* 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.
