* better error message for unexpected renaming (closes #2987)Gravatar gareuselesinge2013-07-29
| | | | git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16641 85f007b7-540e-0410-9357-904b9bb8a0f7
* Revert "Only arguments declared as implicit can be renamed"Gravatar gareuselesinge2013-07-29
| | | | | | This reverts commit 18a89c271d540d794d44e41f50587bb1cad69802. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16640 85f007b7-540e-0410-9357-904b9bb8a0f7
* Declaremods: major refactoring, stop duplicating libobjects in modulesGravatar letouzey2013-07-17
| | | | | | | | | | | | | | | | | | | | | | | When refering to a module / module type, or when doing an include, we do not duplicate and substitution original libobjects immediatly. Instead, we store the module path, plus a substitution. The libobjects are retrieved later from this module path and substituted, typically during a Require. This allows to vastly decrease vo size (up to 50% on some files in the stdlib). More work is done during load (some substitutions), but the extra time overhead appears to be negligible. Beware: all subst_function operations should now be environment-insensitive, since they may be arbitrarily delayed. Apparently only subst_arguments_scope had to be adapted. A few more remarks: - Increased code factorisation between modules and modtypes - Many errors and anomaly are now assert - One hack : brutal access of inner parts of module types (cf handle_missing_substobjs) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16630 85f007b7-540e-0410-9357-904b9bb8a0f7
* More dynamic argument scopesGravatar letouzey2013-07-17
| | | | | | | | | | | | | | | | | | | | When arguments scopes are set manually, nothing new, they stay as they are (until maybe another Arguments invocation). But when argument scopes are computed out of the argument type and the Bind Scope information, this kind of scope is now dynamic: a later Bind Scope will be able to impact the scopes of an earlier constant. For Instance: Definition f (n:nat) := n. About f. (* Argument scope is [nat_scope] *) Bind Scope other_scope with nat. About f. (* Argument scope is [other_scope] *) This allows to get rid of hacks for modifying scopes during functor applications. Moreover, the subst_arguments_scope is now environment-insensitive (needed for forthcoming changes in declaremods). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16626 85f007b7-540e-0410-9357-904b9bb8a0f7

* Making the behavior of "injection ... as ..." more natural:Gravatar herbelin2013-06-02
| | | | | | | | | | | | | - hypotheses are introduced in the left-to-right order - intropatterns have to match the number of generated hypotheses, and, if less, new introduction names are automatically generated - clearing the hypothesis on which injection is applied, if any.

Grammatically, "understanding a term" looks strange. - Investigate whether the inference flags in tacinterp.ml are really what we want (e.g. do we really want that heuristic remains activated when typeclasses are explicitly deactivated, idem in Tacinterp.interp_open_constr where flags are strange). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16499 85f007b7-540e-0410-9357-904b9bb8a0f7

* Coqide: new feedback mechanism for structured contentGravatar gareuselesinge2013-04-25
| | | | | | | | | | | | | | | | | This amounts to a new type of message called "feedback" and defined in Interface to hold structured data. Coq sends feedback messages asynchronously (they are all fetched, like regular messages, together with the main response to a call) and they are related to a specific sentence by an id. Other changes: - CoqOps pushes the sentence to be processed onto the cmd_stack before processing it and pulls it back if Coq.intep fails, in this way the handler for feedback messages can just look at the cmd_stack to find the offset of the sentence to eventually apply the new Gtk.tag. - The class coqops takes in input a coqtop to set its feedback_handle. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16451 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | | | Doing coqtop -l on a file starting with Reset Initial used to fail. To avoid that, we now always place an initial DOT in the libstack. Backtrack.reset_initial has been adapted accordingly: during an interactive session following a Load via coqtop -l (or .coqrc), a Reset Initial will bring back at the start of the interactive session, *not* undoing the initial Load. Note : Reset Initial might hence not be equivalent anymore to BackTo 1. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16449 85f007b7-540e-0410-9357-904b9bb8a0f7

* interface.mli and serialize.ml reworked to avoid copy/paste of typesGravatar gareuselesinge2013-04-19
| | | | | | | | | | | | | | | | | | | | With this commit the types involved in the protocol between Coq and Coqide are written once and for all in interface.mli serialize.ml is monkey code that contains a reified version of these types and the related machinery needed to marshal values in these types to/from xml in a modular way. This file should be automatically generated from the spec of the protocol in an ideal world. Phantom types are used to statically check that the reified form of the types is in sync with the one declared in interface.mli The benefit of this commit is that changing the protocol is easier: one changes the types in interface.mli and lets ocamlc spot all the places that needs to be modified. This is a necessity if one plays with the protocol very often, like in my Paral-ITP branch. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16438 85f007b7-540e-0410-9357-904b9bb8a0f7

* 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
