2016-03-21Creating a dedicated ltac/ folder for Hightactics.Pierre-Marie Pédrot
2016-03-06Moving Ltac traces to Tacexpr and Tacinterp.Pierre-Marie Pédrot
2016-02-22The tactic generic argument now returns a value rather than a glob_expr.Pierre-Marie Pédrot
The glob_expr was actually always embedded as a VFun, so this patch should not change anything semantically. The only change occurs in the plugin API where one should use the Tacinterp.tactic_of_value function instead of Tacinterp.eval_tactic. Moreover, this patch allows to use tactics returning arguments from the ML side.

2015-12-28Implementing non-focussed generic arguments.Pierre-Marie Pédrot
Kind of enhances the situation of bug #4409. Now arguments can be interpreted globally or focussedly in a dynamic fashion because the interpretation function returns a Ftactic.t. The bug is not fixed yet because we should tweak the interpretation of tactic arguments.

2014-09-12Referring to evars by names. Added a parser for evars (but parsing ofHugo Herbelin
instances still to do). Using heuristics to name after the quantifier name it comes. Also added a "sigma" to almost all printing functions.
2014-09-08Removing the XML plugin.Pierre-Marie Pédrot
Left a README, just in case someone will discover the remnants of it decades from now.
2014-09-06Proper interpretation function for tauto.Pierre-Marie Pédrot
Instead of passing glob tactics through the infamous globTacticIn hack and antiquotation feature of the Ltac syntax, we put them in the interpretation environment as closures. This should be used everywhere to get rid of this buggy antiquotation syntax. This fixes bug #2800.
2014-09-06Adding a way to inject tactic closures in interpretation values.Pierre-Marie Pédrot
2014-08-01Add [guard] tactic.Arnaud Spiwack
The [guard] tactic accepts simple tests (on integers) as argument, succeeds if the test passes and fails if the test fails. Together with [numgoal] can be used to fork on the number of goals of a tactic. The syntax is not very robust (in particular [guard n<=1] is correct but not [guard (n<=1)]). Maybe tests should be moved to the general parser to allow for more flexibility.
2014-06-03The tactic interpreter now uses a new type of tactics, throughPierre-Marie Pédrot
the GTac module. A ['a Gtac.t] is a special case of tactic that may depend on the current goals, or not. Internally, it construct a list of results, one for each focussed goal, if the tactic is actually dependent. This allows for an interpretation of whole-goal tactic that does work, which was not the case for the previous implementation, which did to many Proofview.Goal.enter.
2014-05-24Revert "Chasing the goal entering backward while interpreting tactics. This ↵Pierre-Marie Pédrot
required" I tested the commit on the wrong branch... This reverts commit b0364eff4ec8ad5676060d8ca9cdbbb1d9c34d04.
2014-05-24Chasing the goal entering backward while interpreting tactics. This requiredPierre-Marie Pédrot
writing a new primitive recovering the first goal under focus. It sounds a bit hackish, but it does actually work.
2014-05-20Tactics declared through TACTIC EXTEND that are of the formPierre-Marie Pédrot
"foobar" constr(x1) ... constr(xn) are now defined as pure Ltac definitions, and do not add grammar nor printing rules. This partially relies on a hack consisting in retrieving the arguments in the tactic environment rather than as directly passed to the TacExtend node.
2014-03-19Adding phantom types to discriminate normalized goals, and adding a way toPierre-Marie Pédrot
observe non-normalized goals.
2014-03-05Remove many superfluous 'open' indicated by ocamlc -w +33Pierre Letouzey
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.
2014-02-27Tacinterp: spurious enterl.Arnaud Spiwack
This changes the tacinterp API, but only affects (one line of) the MapleMode contrib.
2014-02-27Dead code: eval_ltac_constr.Arnaud Spiwack
2013-11-26Do not use ugly Dyn features in the Quote plugin. Use instead thePierre-Marie Pédrot
provided tactic environment to handle open terms.
2013-11-25Tacinterp: fewer use of old-style goals.Arnaud Spiwack
There are many functions in Tacinterp which use a goal as a proxy for the pair of an environment and an evar_map. But do not build LCF tactics with them. They don't play well with the new style of tactics. I've changed some of them to explicitely take an environment and an evar_map instead.
2013-11-10Centralizing the Ltac-defining functions in Tacenv.ppedrot

2013-11-02Made multiple-goal tactic work after all: .aspiwack
Internalization was done relative to a goal. It doesn't make sense in the case of all:. When we make a tactic with all: the environment for internalization is taken to be the global environment. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17016 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-11-02Getting rid of Goal.here, and all the related exceptions and combinators.aspiwack
It was a bad idea. The new API based on lists seems more sensible. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16969 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-11-02Makes the new Proofview.tactic the basic type of Ltac.aspiwack
On the compilation of Coq, we can see an increase of ~20% compile time on my completely non-scientific tests. Hopefully this can be fixed. There are a lot of low hanging fruits, but this is an iso-functionality commit. With a few exceptions which were not necessary for the compilation of the theories: - The declarative mode is not yet ported - The timeout tactical is currently deactivated because it needs some subtle I/O. The framework is ready to handle it, but I haven't done it yet. - For much the same reason, the ltac debugger is unplugged. It will be more difficult, but will eventually be back. A few comments: I occasionnally used a coercion from [unit Proofview.tactic] to the old [Prooftype.tactic]. It should work smoothely, but loses any backtracking information: the coerced tactics has at most one success. - It is used in autorewrite (it shouldn't be a problem there). Autorewrite's code is fairly old and tricky - It is used in eauto, mostly for "Hint Extern". It may be an issue as time goes as we might want to have various success in a "Hint Extern". But it would require a heavy port of eauto.ml4 - It is used in typeclass eauto, but with a little help from Matthieu, it should be easy to port the whole thing to the new tactic engine, actually simplifying the code. - It is used in fourier. I believe it to be inocuous. - It is used in firstorder and congruence. I think it's ok. Their code is somewhat intricate and I'm not sure they would be easy to actually port. - It is used heavily in Function. And honestly, I have no idea whether it can do harm or not. Updates: (11 June 2013) Pierre-Marie Pédrot contributed the rebase over his new stream based architecture for Ltac matching (r16533), which avoid painfully and expensively working around the exception-throwing control flow of the previous API. (11 October 2013) Rebasing over recent commits (somewhere in r16721-r16730) rendered a major bug in my implementation of Tacticals.New.tclREPEAT_MAIN apparent. It caused Field_theory.v to loop. The bug made rewrite !lemma, rewrite ?lemma and autorewrite incorrect (tclREPEAT_MAIN was essentially tclREPEAT, causing rewrites to be tried in the side-conditions of conditional rewrites as well). The new implementation makes Coq faster, but it is pretty much impossible to tell if it is significant at all. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16967 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-06-22Now, idtac closures use maps instead of association list.ppedrot
The semantics changed slightly so it may break some scripts, though it is very unlikely, as they would have to be quite intricated and poorly written. Indeed, the test-suite passed just fine. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16604 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-06-21Splitted up Genarg in four different levels:ppedrot
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
