* Safe_typing code refactoringGravatar letouzey2013-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - No more modinfo sub-record in the safe_environment record, this was a syntactic pain. senv.modinfo.modpath --> senv.modpath senv.modinfo.variant --> senv.modvariant senv.modinfo.resolver --> senv.modresolver senv.modinfo.resolver_of_param --> senv.paramresolver senv.modinfo.label : removed (can be inferred from modpath) - No more systematic chaining of safe_environment ('old' field). Instead, earlier safe_environment is stored in the modvariant field when necessary (STRUCT and SIG case). - Improved sharing between end_module and end_modtype - More qualified names instead of open, better comments, ... - Some user errors are now checked earlier elsewhere (see for instance vernac_end_segment), so we can turn these errors into asserts. The user error about higher-order include is now algebraic. - Highlight the idea of a state monad in Safe_typing : type 'a safe_transformer = safe_environment -> 'a * safe_environment More systematic code in Global, thanks to 'globalize' function. - Declaremods : less informations stored in openmod_info git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16708 85f007b7-540e-0410-9357-904b9bb8a0f7

* State Transaction MachineGravatar gareuselesinge2013-08-08
| | | | | | | | | | | | | | | | | | | | | The process_transaction function adds a new edge to the Dag without executing the transaction (when possible). The observe id function runs the transactions necessary to reach to the state id. Transaction being on a merged branch are not executed but stored into a future. The finish function calls observe on the tip of the current branch. Imperative modifications to the environment made by some tactics are now explicitly declared by the tactic and modeled as let-in/beta-redexes at the root of the proof term. An example is the abstract tactic. This is the work described in the Coq Workshop 2012 paper. Coq is compile with thread support from now on. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16674 85f007b7-540e-0410-9357-904b9bb8a0f7

* States: frozen states can hold closuresGravatar gareuselesinge2013-05-06
| | | | | | | | States.freeze takes ~marshallable:bool, so that (only) when we want to marshal data to disk/network we can ask the freeze functions of the summary to force lazy values. The flag is propagated to Lib and Summary. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16478 85f007b7-540e-0410-9357-904b9bb8a0f7
* Fix issues with "Reset Initial" in scripts given to coqtop -lGravatar letouzey2013-04-23
| | | | | | | | | | | | | | Doing coqtop -l on a file starting with Reset Initial used to fail. To avoid that, we now always place an initial DOT in the libstack. Backtrack.reset_initial has been adapted accordingly: during an interactive session following a Load via coqtop -l (or .coqrc), a Reset Initial will bring back at the start of the interactive session, *not* undoing the initial Load. Note : Reset Initial might hence not be equivalent anymore to BackTo 1. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16449 85f007b7-540e-0410-9357-904b9bb8a0f7
* code simplifications concerning SummaryGravatar letouzey2013-04-22
| | | | | | | | | | | | | | | - Most of the time, the table registered via Summary.declare_summary is just a single reference. A new function Summary.ref now allows to both declare this ref and register it to summary in one shot. - Clarifications concerning the role of [init_function]. For statically registered tables that don't need a special initializer, just do nothing there (see the new Summary.nop function). Beware: now that Summary exports a function named "ref", any code that do an "open Summary" will probably fail to compile. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16441 85f007b7-540e-0410-9357-904b9bb8a0f7

* Monomorphized a lot of equalities over OCaml integers, thanks toGravatar ppedrot2012-11-08
| | | | | | | | | | | | | | | | | the new Int module. Only the most obvious were removed, so there are a lot more in the wild. This may sound heavyweight, but it has two advantages: 1. 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

* A unified backtrack mechanism, with a basic "Show Script" as side-effectGravatar letouzey2012-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Migrate the backtracking code from ide_slave.ml into a new backtrack.ml. In particular the history stack of commands that used to be there is now non-coqide-specific. ** Adapted commands ** - "Show Script": a basic functional version is restored (and the printing of scripts at Qed in coqtop). No indentation, one Coq command per line, based on the vernac_expr asts recorded in the history stack, printed via Ppvernac. - "Back n" : now mimics the backtrack of coqide: it goes n steps back (both commands and proofs), and maybe more if needed to avoid re-entering a proof (it outputs a warning in this case). - "BackTo n" : still try to go back to state n, but it also handles the proof state, and it may end on some state n' <= n if needed to avoid re-entering a proof. Ideally, it could someday be used by ProofGeneral instead of the complex Backtrack command. ** Compatible commands ** - "Backtrack" is left intact from compatibility with current ProofGeneral. We simply re-synchronize the command history stack after each Backtrack. - "Undo" is kept as a standard command, not a backtracking one, a bit like "Focus". Same for "Restart" and "Abort". All of these are now accepted in coqide (Undo simply triggers a warning). - Undocumented command "Undo To n" (counting from start of proof instead of from end) also keep its semantics, it is simply made compatible with the new stack mechanism. ** New restrictions ** We now forbid backtracking commands (Reset* / Back*) inside files when Load'ing or compiling, or inside VernacList/VernacTime/VernacFail. Too much work dealing with these situation that nobody uses. ** Internal details ** Internally, the command stack differs a bit from what was in Ide_slave earlier (which was inspired by lisp code in ProofGeneral). We now tag commands that are unreachable by a backtrack, due to some proof being finished, aborted, restarted, or partly Undo'ed. This induce a bit of bookkeeping during Qed/Abort/Restart/Undo, but then the backtracking code is straightforward: we simply search backward the first reachable state starting from the desired place. We don't depend anymore on the proof names (apart in the last proof block), It's more robust this way (think of re-entering a M.foo from an outside proof foo). Many internal clarifications in Lib, Vernac, etc. For instance "Reset Initial" is now just a BackTo 1, while "Reset foo" now calls (Lib.label_before_name "foo"), and performs a BackTo to the corresponding label. Concerning Coqide, we directly suppress the regular printing of goals via a flag in Vernacentries. This avoid relying on a classification of commands in Ide_slave as earlier. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15085 85f007b7-540e-0410-9357-904b9bb8a0f7
* Remove undocumented command "Delete foo"Gravatar letouzey2012-03-23
| | | | | | | | | This command isn't trivial to port to the forthcoming evolution of backtracking in coqtop. Moreover, it isn't clear whether this "Delete" works well in advanced situation (was not updating frozen states). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15084 85f007b7-540e-0410-9357-904b9bb8a0f7

* Add type annotations around all calls to Libobject.declare_objectGravatar letouzey2011-11-02
| | | | | | | | | | | | | | | | | These annotations are purely optional, but could be quite helpful when trying to understand the code, and in particular trying to trace which which data-structure may end in the libobject part of a vo. By the way, we performed some code simplifications : - in Library, a part of the REQUIRE objects was unused. - in Declaremods, we removed some checks that were marked as useless, this allows to slightly simplify the stored objects. To investigate someday : in recordops, the RECMETHODS is storing some evar_maps. This is ok for the moment, but might not be in the future (cf previous commit on auto hints). This RECMETHODS was not detected by my earlier tests : not used in the stdlib ? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14627 85f007b7-540e-0410-9357-904b9bb8a0f7

* Coqide: new backtracking code, based on the Backtrack commandGravatar letouzey2011-09-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This approach, inspired by ProofGeneral, is *much* simplier than earlier, and should be more robust (I hope! feedback of testers is welcome). Coqide still continues to send orders like "Rewind 5" for undoing 5 phrases. A stack on the coqtop side (in Ide_slave) convert this phrase count to labels in the sense of Backtrack, and to abort + depth informations concerning proofs. We avoid re-entering finished proofs during Rewind by some extra backtracking until before these proofs. The amount of extra backtracking is then answered by coqtop to coqide. Now: - for go_to_insert (the "goto" button), unlike PG, coqide replays the extra backtracked zone. - for undo_last_step (the "back" button), coqide now leaves the extra backtracked zone undone, just like PG. This happens typically when undoing a Qed, and this should be the only visible semantical change of this patch. Two points to check with Pierre C: - such a coqtop-side stack mapping labels to opened proofs might be interesting to PG, instead of passing lots of info via the prompt and computing stuff in emacs. - Unlike PG, we allow re-entering inside a module / section, while PG retracts to the start of it. Coqide seems to work fine this way, to check. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14455 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.
