* At least made the evar type opaque! There are still 5 remaining unsafeGravatar ppedrot2013-09-18
| | | | | | | | | | | | casts of ints to evars. - 2 in Evarutil and Goal which are really needed, even though the Goal one could (and should) be removed; - 2 in G_xml and Detyping that are there for completeness sake, but that might be made anomalies altogether; - 1 in Newring which is quite dubious at best, and should be fixed. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16786 85f007b7-540e-0410-9357-904b9bb8a0f7

* Added a more efficient way to recover the domain of a map.Gravatar ppedrot2013-08-25
| | | | | | | | | | The extended signature is defined in CMap, and should be compatible with the old one, except that module arguments have to be explicitely named. The implementation itself is quite unsafe, as it relies on the current implementation of OCaml maps, even though that should not be a problem (it has not changed in ages). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16735 85f007b7-540e-0410-9357-904b9bb8a0f7
* 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

* Splitted up Genarg in four different levels:Gravatar ppedrot2013-06-21
| | | | | | | | | | | | | 1. Genarg itself which only defines the abstract datatypes needed. 2. Genintern, first file of interp/, defining the intern and subst functions. 3. Geninterp, first file of tactics/, defining the interp function. 4. Genprint, first file of printing/, dealing with the printers. The Genarg file has no dependency and is in lib/, so that we can put generic arguments everywhere, and in particular in ASTs. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16601 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.

* Added exception enrichment. Now one can define additional arbitraryGravatar ppedrot2013-02-18
| | | | | | | | | | | information worn by exceptions. The implementation is quite hackish but it should work nonetheless. Basically, it adds an additional cell to exceptions arguments, in which you can put whatever you want. By typing invariants, you may not reach this cell by normal means, so it should be safe. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16212 85f007b7-540e-0410-9357-904b9bb8a0f7
* Added backtrace primitives.Gravatar ppedrot2013-01-28
| | | | | | | | | | | | | | | | | | | | | | Using OCaml 3.11+ builtin facilities to record stack frames during exception raising, we can now recover at runtime the backtrace of an uncaught toplevel exception and display it to the user, without the infamous OCaml debugger. The backtrace is displayed when using the [-debug] flag. This requires a bit of discipline, as each time we reraise an exception we need to keep track of those frames we discarded between the previous raise and the current [try-with] branch. Currently, only [Anomaly] is handled, but this can be ported to any exception as long as we add the backtrace info into the exception, and we provide the corresponding handler to [Backtracke.register_backtrace_handler]. Hopefully this should not be to costly, as we only do little work when reraising, and only with the [-debug] flag set. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16166 85f007b7-540e-0410-9357-904b9bb8a0f7
