* 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
* Revised infrastructure for lazy loading of opaque proofsGravatar letouzey2013-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Get rid of the LightenLibrary hack : no more last-minute collect of opaque terms and Obj.magic tricks. Instead, we make coqc accumulate the opaque terms as soon as constant_bodies are created outside sections. In these cases, the opaque terms are placed in a special table, and some (DirPath.t * int) are used as indexes in constant_body. In an interactive session, the local opaque terms stay directly stored in the constant_body. The structure of .vo file stays similar : magic number, regular library structure, digest of the first part, array of opaque terms. In addition, we now have a final checksum for checking the integrity of the whole .vo file. The other difference is that lazy_constr aren't changed into int indexes in .vo files, but are now coded as (substitution list * DirPath.t * int). In particular this approach allows to refer to opaque terms from another library. This (and accumulating substitutions in lazy_constr) seems to greatly help decreasing the size of opaque tables : -20% of vo size on the standard library :-). The compilation times are slightly better, but that can be statistic noise. The -force-load-proofs isn't active anymore : it behaves now just like -lazy-load-proofs. The -dont-load-proofs mode has slightly changed : opaque terms aren't seen as axioms anymore, but accessing their bodies will raise an error. Btw, API change : Declareops.body_of_constant now produces directly a constr option instead of a constr_substituted option git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16382 85f007b7-540e-0410-9357-904b9bb8a0f7

* Robust display of NotConvertibleTypeField errors (fix #3008, #2995)Gravatar letouzey2013-03-21
| | | | | | | | | | | | | | Since the nametab isn't aware of everything needed to print mismatched types (cf the bug test-cases), we create a robust term printer that known how to print a fully-qualified name when [shortest_qualid_of_global] has failed. These Printer.safe_pr_constr and alii are meant to never fail (at worse they display "??", for instance when the env isn't rich enough). Moreover, the environnement may have changed between the raise of NotConvertibleTypeField and its display, so we store the original env in the exception. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16342 85f007b7-540e-0410-9357-904b9bb8a0f7

* Ppvernac: no globalization for printing ltac definitionsGravatar letouzey2013-03-17
| | | | | | | | | | | | | | | This way, ppvernac is entirely at the "raw" level : constr_expr, raw_tactic_expr, ... Using globalization for ltac was awkward since it was the only such place handled this way. Moreover the env necessary for pr_glob_tactic was possibly wrong (cf last commit concerning module params), and the pr_glob_tactic was raising exceptions from time to time (typically on a "eval ..." ltac raising a "tactic expected"). Feel free to revert if this globalization has indeed an interest I missed. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16312 85f007b7-540e-0410-9357-904b9bb8a0f7

* Modules and ppvernac, sequel of Enrico's commit 16261Gravatar letouzey2013-03-13
| | | | | | | | | | | | After some investigation, I see no reason to try to hack the nametab in ppvernac, since everything happens there at a lower level (constr_expr).

Monomorphization is explicit, hence we do not miss particular optimizations of equality when doing it carelessly with the generic equality. 2. When we have removed all the generic equalities on integers, we will be able to write something like "let (=) = ()" to retrieve all its other uses (mostly faulty) spread throughout the code, statically. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15957 85f007b7-540e-0410-9357-904b9bb8a0f7
