| * Lets Hints/Instances take an optional patternGravatar Matthieu Sozeau2016-11-03
| | | | | | | | | | | | | | | | | | In addition to a priority, cleanup the interfaces for passing this information as well. The pattern, if given, takes priority over the inferred one. We only allow Existing Instances gr ... gr | pri. for now, without pattern, as before. Make the API compatible to 8.5 as well.

| | | | | | | Suggested by R. Krebbers and C. Cohen, this makes modes more applicable, by allowing to trigger resolution on partially instantiated indices. This is a rough but fast approximation of the pattern on which one would like instances to apply.

* Proof using: let-in policy, optional auto-clear, forward closure*Gravatar Enrico Tassi2015-10-08
| | | | | | | | | | | | | - "Proof using p*" means: use p and any section var about p. - Simplify the grammar/parser for proof using <expression>. - Section variables with a body (let-in) are pulled in automatically since they are safe to be used (add no extra quantification) - automatic clear of "unused" section variables made optional: Set Proof Using Clear Unused. since clearing section hypotheses does not "always work" (e.g. hint databases are not really cleaned) - term_typing: trigger a "suggest proof using" message also for Let theorems.

| | | | | | | | | | | | | of resulution for goals whose head is "ref". + means the argument is an input and shouldn't contain an evar, otherwise resolution fails. This generalizes the Typeclasses Strict Resolution option which prevents resolution to fire on underconstrained typeclass constraints, now the criterion can be applied to specific parameters. Also cleanup auto/eauto code, uncovering a potential backwards compatibility issue: in cases the goal contains existentials, we never use the discrimination net in auto/eauto. We should try to set this on once the contribs are stabilized (the stdlib goes through when the dnet is used in these cases).

| | | | | | | | 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.
* Proof_using: new syntax + suggestionGravatar Enrico Tassi2014-01-05
| | | | | | | | | | | | | | | | | | | | | | | | Proof using can be followed by: - All : all variables - Type : all variables occurring in the type - expr: - (a b .. c) : set - expr + expr : set union - expr - expr : set difference - -expr : set complement (All - expr) Exceptions: - a singleton set can be written without parentheses. This also allows the implementation of named sets sharing the same name space of section hyps ans write - bla - x : where bla is defined as (a b .. x y) elsewhere. - if expr is just a set, then parentheses can be omitted This module also implements some AI to tell the user how he could decorate "Proof" with a "using BLA" clause. Finally, one can Set Default Proof Using "str" to any string that is used whenever the "using ..." part is missing. The coding of this sucks a little since it is the parser that applies the default.

* More functional implementation of locality_flag and program_modeGravatar gareuselesinge2013-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit introduces 2 new vernac_expr constructors: - VernacLocal (b,v) that represents a vernacular v with the "Local" modifier - VernacProgram v that represents a vernacular v with the "Program" modifier This allows the parser to avoid using side effects to model the two modifiers, that are now represented in the AST. This also decouples the parsing phase from the interpretation phase, since parsing a second phrase does not alter the locality flag for the first phrase. As a consequence all the locality_flag components of vernac_expr have been removed, but for the ones that (for retro compatibility) allow an "infix" Local flag. In these cases the boolean is renamed obsolete_locality (as the grammar entry that parses it), and during interpretation we check that at most one locality flag is specified, using the idiom (where the input local is the obsolete one): let local = enforce_XXX_locality locality local in Another improvement is that the default locality is not chosen in the parser, but in the interpreter where the idiom let local = make_XXX_locality locality in is used to default the locality to XXX (module/section/whatever). Unfortunately not all side effects have been removed: - Flags.program_mode is still used to signal that we are in program mode - Locality.LocalityFixme.* functions are used in commands that do not have an AST, but are parsed as VernacExtend (see vernacinterp.ml) I guess one could fix the latter case systematically adding an extra argument "locality" to commands attached using VERNAC COMMAND EXTEND. Fixing plugins adding commands that honour "Local" should look like this: VERNAC COMMAND EXTEND Set_Solver | [ "Obligation" "Tactic" ":=" tactic(t) ] -> [ set_default_tactic - (Locality.use_section_locality ()) + (Locality.make_section_locality (Locality.LocalityFixme.consume ())) (Tacintern.glob_tactic t) ] END In any case the side effects are set/consumed within then interpretation phase, and not set during the parsing phase and consumed during the interpretation phase. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16396 85f007b7-540e-0410-9357-904b9bb8a0f7

* 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

* 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

* Here comes the commit, announced long ago, of the new tactic engine.Gravatar aspiwack2010-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12961 85f007b7-540e-0410-9357-904b9bb8a0f7
