* Remove many superfluous 'open' indicated by ocamlc -w +33Gravatar Pierre Letouzey2014-03-05
| | | | | | | | 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.
* 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

* Noise for nothingGravatar pboutill2012-03-02
| | | | | | | | | | | Util only depends on Ocaml stdlib and Utf8 tables. Generic pretty printing and loc functions are in Pp. Generic errors are in Errors. + Training white-spaces, useless open, prlist copies random erasure. Too many "open Errors" on the contrary. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15020 85f007b7-540e-0410-9357-904b9bb8a0f7

* Remove the svn-specific $Id$ annotationsGravatar letouzey2010-04-29
| | | | | | | | | | | - Many of them were broken, some of them after Pierre B's rework of mli for ocamldoc, but not only (many bad annotation, many files with no svn property about Id, etc) - Useless for those of us that work with git-svn (and a fortiori in a forthcoming git-only setting) - Even in svn, they seem to be of little interest git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12972 85f007b7-540e-0410-9357-904b9bb8a0f7
* This big commit addresses two problems:Gravatar soubiran2009-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1- Management of the name-space in a modular development / sharing of non-logical objects. 2- Performance of atomic module operations (adding a module to the environment, subtyping ...). 1- There are 3 module constructions which derive equalities on fields from a module to another: Let P be a module path and foo a field of P Module M := P. Module M. Include P. ... End M. Declare Module K : S with Module M := P. In this 3 cases we don't want to be bothered by the duplication of names. Of course, M.foo delta reduce to P.foo but many non-logical features of coq do not work modulo conversion (they use eq_constr or constr_pat object). To engender a transparent name-space (ie using P.foo or M.foo is the same thing) we quotient the name-space by the equivalence relation on names induced by the 3 constructions above. To implement this, the types constant and mutual_inductive are now couples of kernel_names. The first projection correspond to the name used by the user and the second projection to the canonical name, for example the internal name of M.foo is (M.foo,P.foo). So: ************************************************************************************* * Use the eq_(con,mind,constructor,gr,egr...) function and not = on names values * ************************************************************************************* Map and Set indexed on names are ordered on user name for the kernel side and on canonical name outside. Thus we have sharing of notation, hints... for free (also for a posteriori declaration of them, ex: a notation on M.foo will be avaible on P.foo). If you want to use this, use the appropriate compare function defined in name.ml or libnames.ml. 2- No more time explosion (i hoppe) when using modules i have re-implemented atomic module operations so that they are all linear in the size of the module. We also have no more unique identifier (internal module names) for modules, it is now based on a section_path like mechanism => we have less substitutions to perform at require, module closing and subtyping but we pre-compute more information hence if we instanciate several functors then we have bigger vo. Last thing, the checker will not work well on vo(s) that contains one of the 3 constructions above, i will work on it soon... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12406 85f007b7-540e-0410-9357-904b9bb8a0f7
