* The new ocaml compiler (4.00) has a lot of very cool warnings,Gravatar regisgia2012-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | especially about unused definitions, unused opens and unused rec flags. The following patch uses information gathered using these warnings to clean Coq source tree. In this patch, I focused on warnings whose fix are very unlikely to introduce bugs. (a) "unused rec flags". They cannot change the semantics of the program but only allow the inliner to do a better job. (b) "unused type definitions". I only removed type definitions that were given to functors that do not require them. Some type definitions were used as documentation to obtain better error messages, but were not ascribed to any definition. I superficially mentioned them in one arbitrary chosen definition to remove the warning. This is unaesthetic but I did not find a better way. (c) "unused for loop index". The following idiom of imperative programming is used at several places: "for i = 1 to n do that_side_effect () done". I replaced "i" with "_i" to remove the warning... but, there is a combinator named "Util.repeat" that would only cost us a function call while improving readibility. Should'nt we use it? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15797 85f007b7-540e-0410-9357-904b9bb8a0f7

* Severe reorganisation of the code of tactics in Proofview.Gravatar aspiwack2012-07-11
| | | | | | | | | | | All the purely monadic code has been moved to a new module Monads, where, I'm afraid to confess, I got to use a number of proof transformers to modularise the definition of tactics. It is still not easy to understand (why would it with backtracking support?) but at least it's more robust, cleaner, and more extensible. Plus there is now a Proofview.tclORELSE which will be used to interprete the Ltac tactical (t1 || t2). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15596 85f007b7-540e-0410-9357-904b9bb8a0f7

* info_trivial, info_auto, info_eauto, and debug (trivial|auto)Gravatar letouzey2012-03-30
| | | | | | | | | | | | | | | | | | | | | | | To mitigate the lack of a general "info" tactical, let's introduce some specialized tactics info_trivial, info_auto and info_eauto that display the basic tactics used when solving a goal. We also add tactics "debug trivial" and "debug auto" which display every basic tactics attempted by trivial or auto. Triggering the "info" or "debug" mode for auto, eauto, trivial can also be done now via global options, such as Set Debug Auto or Set Info Eauto. In case both debug and info modes are activated, the debug mode takes precedence. NB: it would be nice to name these tactics "info xxx" instead of "info_xxx", but I don't see how to implement a "info eauto" in eauto.ml4 (hence by TACTIC EXTEND) while keeping a generic "info foo" tactic in g_ltac.ml4 (useful to display a nice message about the unavailability of the general info). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15103 85f007b7-540e-0410-9357-904b9bb8a0f7

* A unified backtrack mechanism, with a basic "Show Script" as side-effectGravatar letouzey2012-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Migrate the backtracking code from ide_slave.ml into a new backtrack.ml. In particular the history stack of commands that used to be there is now non-coqide-specific. ** Adapted commands ** - "Show Script": a basic functional version is restored (and the printing of scripts at Qed in coqtop). No indentation, one Coq command per line, based on the vernac_expr asts recorded in the history stack, printed via Ppvernac. - "Back n" : now mimics the backtrack of coqide: it goes n steps back (both commands and proofs), and maybe more if needed to avoid re-entering a proof (it outputs a warning in this case). - "BackTo n" : still try to go back to state n, but it also handles the proof state, and it may end on some state n' <= n if needed to avoid re-entering a proof. Ideally, it could someday be used by ProofGeneral instead of the complex Backtrack command. ** Compatible commands ** - "Backtrack" is left intact from compatibility with current ProofGeneral. We simply re-synchronize the command history stack after each Backtrack. - "Undo" is kept as a standard command, not a backtracking one, a bit like "Focus". Same for "Restart" and "Abort". All of these are now accepted in coqide (Undo simply triggers a warning). - Undocumented command "Undo To n" (counting from start of proof instead of from end) also keep its semantics, it is simply made compatible with the new stack mechanism. ** New restrictions ** We now forbid backtracking commands (Reset* / Back*) inside files when Load'ing or compiling, or inside VernacList/VernacTime/VernacFail. Too much work dealing with these situation that nobody uses. ** Internal details ** Internally, the command stack differs a bit from what was in Ide_slave earlier (which was inspired by lisp code in ProofGeneral). We now tag commands that are unreachable by a backtrack, due to some proof being finished, aborted, restarted, or partly Undo'ed. This induce a bit of bookkeeping during Qed/Abort/Restart/Undo, but then the backtracking code is straightforward: we simply search backward the first reachable state starting from the desired place. We don't depend anymore on the proof names (apart in the last proof block), It's more robust this way (think of re-entering a M.foo from an outside proof foo). Many internal clarifications in Lib, Vernac, etc. For instance "Reset Initial" is now just a BackTo 1, while "Reset foo" now calls (Lib.label_before_name "foo"), and performs a BackTo to the corresponding label. Concerning Coqide, we directly suppress the regular printing of goals via a flag in Vernacentries. This avoid relying on a classification of commands in Ide_slave as earlier. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15085 85f007b7-540e-0410-9357-904b9bb8a0f7

* Pfedit: avoid Undoing too muchGravatar letouzey2012-03-21
| | | | | | | | | | | | | | | | | | It seems that we can currently do a successful Undo (but not two!) on a freshly started Lemma. Let's add a depth check on Pfedit.undo to avoid that. This way, we cannot Undo to depth < 1 (with 1 being the initial depth of a lemma). Simplier implementation of Pfedit.restart : it is Pfedit.undo_todepth 1. This extra initial step in the Undo Stack has probably something to see with the Lemma argument introduction. For instance, before this patch we had: Lemma test n : n+0=n. Restart.

* Fixing alpha-conversion bug #2723 introduced in r12485-12486.Gravatar herbelin2012-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The optimisation done of Namegen.visibly_occur_id did not preserve the previous behavior when pr_constr/constr_extern/detype were called on a term with free rel variables. We backtrack on it to go back to the 8.2 behavior. Seized this opportunity to clarify the meaning of the at_top flag in constrextern.ml and printer.ml and to rename it into goal_concl_style. The badly-named at_top flag was introduced in Coq 6.3 in 1999 to mean that when printing variables bound in the goal, names had to avoid the names of the variables of the goal context, so as to keep naming stable when using "intro"; in r4458, printing improved by not avoiding names that were short names of global definitions, e.g. "S", or "O" (except when the at_top flag was on for compatibility reasons). Other printing strategies could be possible in the non-goal-concl-style mode. For instance, all bound variables could be made distinct in a given expression, even if no clash occur, therefore following so-called Barendregt's convention. This could be done by setting "avoid" to "ids_of_rel_context (rel_context env)" in extern_constr and extern_type (and then, Namegen.visibly_occur_id could be re-simplified again!). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15067 85f007b7-540e-0410-9357-904b9bb8a0f7
