| | | | | | | | | | | | | | | | | | | - Revised Coqtop.parse_args in a cleaner and lighter style - Improved error message in case of argument parse failure: * tell which option is expecting a related argument * in case of unknown options, warn about them all at once * do not hide the previous error messages by filling the screen with usage(). Instead, suggest the use of --help. - Specialized boolean config field Coq_config.arch_is_win32 - Faster Envars.coqlib, which is back to (unit->string), and just access Flags.coqlib. Caveat: it must be initialized once via Envars.set_coqlib - Avoid keeping an opened channel to the "revision" file - Direct load of theories/init/prelude.vo, no detour via Loadpath Beware : ./configure must be runned after this commit git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16726 85f007b7-540e-0410-9357-904b9bb8a0f7

* Declarations.mli: reorganization of modular structuresGravatar letouzey2013-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The earlier type [struct_expr_body] was far too broad, leading to code with unclear invariants, many "assert false", etc etc. Its replacement [module_alg_expr] has only three constructors: * MEident * MEapply : note the module_path as 2nd arg, no more constraints here * MEwith : no more constant_body inside, constr is just fine But no more SEBfunctor or SEBstruct constructor here (see below). This way, this datatype corresponds to algebraic expressions, i.e. anything that can appear in non-interactive modules. In fact, it even coincides now with [Entries.module_struct_entry]. - Functor constructors are now necessarily on top of other structures thanks to a generic [functorize] datatype. - Structures are now separated from algebraic expressions by design : the [mod_type] and [typ_expr] fields now only contain structures (or functorized structures), while [mod_type_alg] and [typ_expr_alg] are restricted to algebraic expressions only. - Only the implementation field [mod_expr] could be either algebraic or structural. We handle this via a specialized datatype [module_implementation] with four constructors: * Abstract : no implementation (cf. for instance Declare Module) * Algebraic(_) : for non-interactive modules, e.g. Module M := N. * Struct(_) : for interactive module, e.g. Module M : T. ... End M. * FullStruct : for interactive module with no type restriction. The [FullStruct] is a particular case of [Struct] where the implementation need not be stored at all, since it is exactly equal to its expanded type present in [mod_type]. This is less fragile than hoping as earlier that pointer equality between [mod_type] and [mod_expr] will be preserved... - We clearly emphasize that only [mod_type] and [typ_expr] are relevant for the kernel, while [mod_type_alg] and [typ_expr_alg] are there only for a nicer extraction and shorter module printing. [mod_expr] is also not accessed by the kernel, but it is important for Print Assumptions later. - A few implicit invariants remain, for instance "no MEwith in mod_expr", see the final comment in Declarations - Heavy refactoring of module-related files : modops, mod_typing, safe_typing, declaremods, extraction/extract_env.ml ... - Coqchk has been adapted accordingly. The code concerning MEwith in Mod_checking is now gone, since we cannot have any in mod_expr. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16712 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

* Removed the distinction between generic Ltac vars and Let/IntroGravatar ppedrot2013-06-27

Ltac semantics was sligthly changed, as it required introducing a lot of additional coercions from goal variables to other types.

| | | | | | | | | | | | | | | | | | 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.

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: Globalization feedback (proof of concept)Gravatar gareuselesinge2013-04-25
| | | | | | | | | | | | | | | | | | | | A new feedback message for globalization infos can be sent by Coq to Coqide. Coqide stores the information in the proof of concept module wg_Tooltip, that also sets things up so that these infos are displayed as a tooltip when the mouse is over the text they are attached to. These infos are available only on locked text, and on the text just processed in the case of an error (on this piece of text, they vanish as the error tag vanishes as soon as the user edits the text). wg_Tooltip stocks these infos as lazy string. This is not needed in the proof of concept, but is necessary to scale up: Coq may not generate the full piece of info when the message is sent (because of high computational cost or big size) and just send an id; later on, when/if the user asks for the piece of info, the gui requests the info explicitly using the id. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16456 85f007b7-540e-0410-9357-904b9bb8a0f7
