2011-08-11SearchAbout and similar: add a customizable blacklistletouzey
Instead of hard-coding in search.ml some substrings such as "_admitted" or "_subproof" we don't want to see in results of SearchAbout and co, we now have a user command: Add Search Blacklist "foo". Remove Search Blacklist "foo". (* the opposite *) Print Table Search Blacklist. (* the current state *) In Prelude.v, three substrings are blacklisted originally: - "_admitted" for internal lemmas due to admit. - "_subproof" for internal lemmas due to abstract. - "Private_" for hiding auxiliary modules not meant for global usage. Note that substrings are searched in the fully qualified names of the available lemmas (e.g. "Coq.Init.Peano.plus"). This commit also adds the prefix "Private_" to some internal modules in Numbers, Z, N, etc. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14408 85f007b7-540e-0410-9357-904b9bb8a0f7
2011-08-10Propagated information from the reduction tactics to the kernel soherbelin
that the kernel conversion solves the delta/delta critical pair the same way the tactics did. This allows to improve Qed time when slow down is due to conversion having (arbitrarily) made the wrong choice. Propagation is done thanks to a new kind of cast called REVERTcast. Notes: - Vm conversion not modified - size of vo generally grows because of additional casts - this remains a heuristic... for the record, when a reduction tactic is applied on the goal t leading to new goal t', this is translated in the kernel in a conversion t' <= t where, hence, reducing in t' must be preferred; what the propagation of reduction cast to the kernel does not do is whether it is preferable to first unfold c or to first compare u' and u in "c u' = c u"; in particular, intermediate casts are sometimes useful to solve this kind of issues (this is the case e.g. in Nijmegen/LinAlg/subspace_dim.v where the combination "simpl;red" needs the intermediate cast to ensure Qed answers quickly); henceforth the merge of nested casts in mkCast is deactivated - for tactic "change", REVERTcast should be used when conversion is in the hypotheses, but convert_hyp does not (yet) support this (would require e.g. that convert_hyp overwrite some given hyp id with a body-cleared let-binding new_id := Cast(old_id,REVERTCast,t)) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14407 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-08-10Less ambitious application of a notation for eq_rect. We proposedherbelin
"rewrite Heq in H" but "rewrite" is sometimes used by users and I don't want to have to change their file. The solution to put the notations in a module does not work with name "rewrite" because loading the module would change the status of "rewrite" from simple ident to keyword (and we cannot declare "rewrite" as an ident, as shown in previous commit). Then we come back on notation "rew" (this name is also used by some users), in a module. This continues commit r14366 and r14390 and improves on the level of the notation. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14400 85f007b7-540e-0410-9357-904b9bb8a0f7
2011-08-10Partly revert commit r14389 about relaxing the condition for being a keywordherbelin
(it does not work) Indeed, if a rule in operconstr at some level starts with an ident, it has to be declared as a keyword because other rules whose leftmost call is a call to operconstr will eventually the top level "200" even thought this leftmost operconstr might be declared at a lower level. This is for instance the reason why "True /\ forall x, x=0" is parsed even though /\ expects arguments at level less than 80 and forall is at level 200. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14399 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-08-09Coqide: revised parsing of coq sentencesletouzey
In particular, grouping { and } delimiters is now allowed. The only place where blank (i.e. space or newline or eof) is mandatory is after dots. For instance "{{tac. }{tac. }}" is ok, while "tac.}" is not seen as containing any sentence delimiter but rather the inner-sentence token ".}", that might have been registered (or not) to Coq by the user via some tactic or constr notation. This way, coqide should be in sync with what is accepted by coqtop. Current cvs version of proofgeneral is slightly more laxist, but this will probably be harmonized soon. Technically, we cannot rely anymore on functions like forward_to_tag_toggle, since two delimiters "}}" could be adjacent, hence no toogle of the corresponding tag. Instead, we use a simplier (less efficient ?) iterative search. When retagging a zone after some edition, we retag up to a real "." delimiter (or eof), since the status of "{" "}" as delimiters is too fragile to be trusted after edition. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14394 85f007b7-540e-0410-9357-904b9bb8a0f7
2011-08-09In coqtop, a terminating "." must now be followed by a blank or eof.letouzey
This way, we forbid contiguous sentences like "tac.{tac.}", which should now be written with at least 2 spaces: "tac. {tac. }" This should avoid confusion if a user declare a notation involving ".{" or ".}" as tokens. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14393 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-08-08New proposition "rewrite Heq in H" for eq_rect (assuming that there isherbelin

2011-08-08Be a bit less aggressive in declaring idents as keywords in notationsherbelin
(an articulating ident needs to be a keyword if the constr entry that preceeds it is higher than the level of applications). Also fixed is_ident_not_keyword which only looked at the first letter and at the keyword status to decide if a token is an ident. This allowed to simplified define_keywords in Metasyntax. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14389 85f007b7-540e-0410-9357-904b9bb8a0f7
