* Vernac classification streamlined (handles VERNAC EXTEND)Gravatar gareuselesinge2013-08-08
| | | | | | | | | | | | | | | | | | | | | | | The warning output by vernacextend when the classifier is missing is the documentation of this commit: Warning: Vernac entry "Foo" misses a classifier. A classifier is a function that returns an expression of type vernac_classification (see Vernacexpr). You can: - Use '... EXTEND Foo CLASSIFIED AS QUERY ...' if the new vernacular command does not alter the system state; - Use '... EXTEND Foo CLASSIFIED AS SIDEFF ...' if the new vernacular command alters the system state but not the parser nor it starts a proof or ends one; - Use '... EXTEND Foo CLASSIFIED BY f ...' to specify a global function f. The function f will be called passing "Foo" as the only argument; - Add a specific classifier in each clause using the syntax: '[...] => [ f ] -> [...]'. Specific classifiers have precedence over global classifiers. Only one classifier is called. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16680 85f007b7-540e-0410-9357-904b9bb8a0f7
* Uniformizing generic argument types.Gravatar ppedrot2013-06-06
| | | | | | | | | | | | | | | | | | Now, instead of having three unrelated types describing a dynamic type at each level (raw, glob, top), we have a "('a, 'b, 'c) genarg_type" whose parameters describe the reified type at each level. This has various advantages: - No more code duplication to handle the three level separately; - Safer code: one is not authorized to mix unrelated types when what was morally expected was a genarg_type. - Each level-specialized representation can be accessed through well-typed projections: rawwit, glbwit and topwit. Documenting a bit Genarg b.t.w. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16564 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
* Pptactic.pr_raw_tactic is now without env argumentGravatar letouzey2013-03-14
| | | | | | | This env argument was just there by analogy with the glob_tactic case, and actually ignored for raw_tactic git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16301 85f007b7-540e-0410-9357-904b9bb8a0f7

This also permits to put Pp in Clib, because it does not depend on CAMLP4/5 anymore. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15475 85f007b7-540e-0410-9357-904b9bb8a0f7
