2016-07-01Add and document match, fix and cofix reduction flags.Maxime Dénès
2016-07-01Separate flags for fix/cofix/match reduction and clean reduction function names.Maxime Dénès
This is a reimplementation of Hugo's PR#117. We are trying to address the problem that the name of some reduction functions was not saying what they were doing (e.g. whd_betadeltaiota was doing let-in reduction). Like PR#117, we are careful that no function changed semantics without changing the names. Porting existing ML code should be a matter of renamings a few function calls. Also, we introduce more precise reduction flags fMATCH, fFIX, fCOFIX collectively denominated iota. We renamed the following functions: Closure.betadeltaiota -> Closure.all Closure.betadeltaiotanolet -> Closure.allnolet Reductionops.beta -> Closure.beta Reductionops.zeta -> Closure.zeta Reductionops.betaiota -> Closure.betaiota Reductionops.betaiotazeta -> Closure.betaiotazeta Reductionops.delta -> Closure.delta Reductionops.betalet -> Closure.betazeta Reductionops.betadelta -> Closure.betadeltazeta Reductionops.betadeltaiota -> Closure.all Reductionops.betadeltaiotanolet -> Closure.allnolet Closure.no_red -> Closure.nored Reductionops.nored -> Closure.nored Reductionops.nf_betadeltaiota -> Reductionops.nf_all Reductionops.whd_betadelta -> Reductionops.whd_betadeltazeta Reductionops.whd_betadeltaiota -> Reductionops.whd_all Reductionops.whd_betadeltaiota_nolet -> Reductionops.whd_allnolet Reductionops.whd_betadelta_stack -> Reductionops.whd_betadeltazeta_stack Reductionops.whd_betadeltaiota_stack -> Reductionops.whd_all_stack Reductionops.whd_betadeltaiota_nolet_stack -> Reductionops.whd_allnolet_stack Reductionops.whd_betadelta_state -> Reductionops.whd_betadeltazeta_state Reductionops.whd_betadeltaiota_state -> Reductionops.whd_all_state Reductionops.whd_betadeltaiota_nolet_state -> Reductionops.whd_allnolet_state Reductionops.whd_eta -> Reductionops.shrink_eta Tacmach.pf_whd_betadeltaiota -> Tacmach.pf_whd_all Tacmach.New.pf_whd_betadeltaiota -> Tacmach.New.pf_whd_all And removed the following ones: Reductionops.whd_betaetalet Reductionops.whd_betaetalet_stack Reductionops.whd_betaetalet_state Reductionops.whd_betadeltaeta_stack Reductionops.whd_betadeltaeta_state Reductionops.whd_betadeltaeta Reductionops.whd_betadeltaiotaeta_stack Reductionops.whd_betadeltaiotaeta_state Reductionops.whd_betadeltaiotaeta They were unused and having some reduction functions perform eta is confusing as whd_all and nf_all don't do it.
2016-06-29A new infrastructure for warnings.Maxime Dénès
On the user side, coqtop and coqc take a list of warning names or categories after -w. No prefix means activate the warning, a "-" prefix means deactivate it, and "+" means turn the warning into an error. Special categories include "all", and "default" which contains the warnings enabled by default. We also provide a vernacular Set Warnings which takes the same flags as argument. Note that coqc now prints warnings. The name and category of a warning are printed with the warning itself. On the developer side, Feedback.msg_warning is still accessible, but the recommended way to print a warning is in two steps: 1) create it by: let warn_my_warning = CWarnings.create ~name:"my-warning" ~category:"my-category" (fun args -> Pp.strbrk ...) 2) print it by: warn_my_warning args

2016-06-18Adding eintros to respect the e- prefix policy.Hugo Herbelin
In pat%constr, creating new evars is now allowed only if "eintros" is given, i.e. "intros" checks that no evars are created, and similarly e.g. for "injection ... as ... pat%constr". The form "eintros [...]" or "eintros ->" with the case analysis or rewrite creating evars is now also supported. This is not a commitment to say that it is good to have an e- modifier to tactics. It is just to be consistent with the existing convention. It seems to me that the "no e-" variants are good for beginners. However, expert might prefer to use the e-variants by default. Opinions from teachers and users would be useful. To be possibly done: do that [= ...] work on hypotheses with side conditions or parameters based on the idea that they apply the full injection and not only the restriction of it to goals which are exactly an equality, as it is today.

2016-06-15Remove the syntax changes introduced by this branch.Pierre-Marie Pédrot
We decided to only export the API, so that an external plugin can provide this feature without having to merge it in current Coq trunk. This postpones the attribute implementation in vernacular commands after 8.6.
2016-06-14Assume totality: dedicated type rather than boolArnaud Spiwack
The rational is that 1. further typing flags may be available in the future 2. it makes it easier to trace and document the argument
2016-06-08Compilation via pack for plugins of the stdlibPierre Letouzey
For now, the pack name reuse the previous .cma name of the plugin, (extraction_plugin, etc). The earlier .mllib files in plugins are now named .mlpack. They are also handled by bin/ocamllibdep, just as .mllib. We've slightly modified ocamllibdep to help setting the -for-pack options: in *.mlpack.d files, there are some extra variables such as foo/bar_FORPACK := -for-pack Baz when foo/bar.ml is mentioned in baz.mlpack. When a plugin is calling a function from another plugin, the name need to be qualified (Foo_plugin.Bar.baz instead of Bar.baz). Btw, we discard the generated files plugins/*/*_mod.ml, they are obsolete now, replaced by DECLARE PLUGIN. Nota: there's a potential problem in the micromega directory, some .ml files are linked both in micromega_plugin and in csdpcert. And we now compile these files with a -for-pack, even if they are not packed in the case of csdpcert. In practice, csdpcert seems to work well, but we should verify with OCaml experts.
2016-06-02A slight phase of documentation and uniformization of names ofHugo Herbelin
functions about interpretation, internalization, externalization of notations. Main syntactic changes: - subst_aconstr_in_glob_constr -> instantiate_notation_constr (because aconstr has been renamed to notation_constr long time ago) - extern_symbol -> extern_notation (because symbol.ml has been renamed to notation.ml long time ago) - documentation of notations_ops.mli Main semantic changes: - Notation_ops.eq_glob_constr which was partial eq disappears: use glob_constr_eq instead - In particular, this impacts a change on funind which now use the (fully implemented) glob_constr_eq Somehow, instantiate_notation_constr should be in notation_ops.ml for symmetry with match_notation_constr but it is bit painful to do.
2016-05-31Feedback cleanupEmilio Jesus Gallego Arias
This patch splits pretty printing representation from IO operations. - `Pp` is kept in charge of the abstract pretty printing representation. - The `Feedback` module provides interface for doing printing IO. The patch continues work initiated for 8.5 and has the following effects: - The following functions in `Pp`: `pp`, `ppnl`, `pperr`, `pperrnl`, `pperr_flush`, `pp_flush`, `flush_all`, `msg`, `msgnl`, `msgerr`, `msgerrnl`, `message` are removed. `Feedback.msg_*` functions must be used instead. - Feedback provides different backends to handle output, currently, `stdout`, `emacs` and CoqIDE backends are provided. - Clients cannot specify flush policy anymore, thus `pp_flush` et al are gone. - `Feedback.feedback` takes an `edit_or_state_id` instead of the old mix. Lightly tested: Test-suite passes, Proof General and CoqIDE seem to work.

2016-03-17Removing the special status of generic arguments defined by Coq itself.Pierre-Marie Pédrot
This makes the TACTIC EXTEND macro insensitive to Coq-defined arguments. They now have to be reachable in the ML code. Note that this has some consequences, as the previous macro was potentially mixing grammar entries and arguments as long as their name was the same. Now, each genarg comes with its grammar instead, so there is no way to abuse the macro.
2016-03-17Removing the special status of generic entries defined by Coq itself.Pierre-Marie Pédrot
The ARGUMENT EXTEND macro was discriminating between parsing entries known statically, i.e. defined in Pcoq and unknown entires. Although simplifying a bit the life of the plugin writer, it made actual interpretation difficult to predict and complicated the code of the ARGUMENT EXTEND macro. After this patch, all parsing entries and generic arguments used in an ARGUMENT EXTEND macro must be reachable by the ML code. This requires adding a few more "open Pcoq.X" and "open Constrarg" here and there.

This gets rid of brittle code written in ML files through Ltac quotations, and reduces the dependance of Coq to such a feature. This also fixes the particular instance of bug #2800, although the underlying issue is still there.

2016-02-09CLEANUP: Context.{Rel,Named}.Declaration.tMatej Kosik
Originally, rel-context was represented as: Context.rel_context = Names.Name.t * Constr.t option * Constr.t Now it is represented as: Context.Rel.t = LocalAssum of Names.Name.t * Constr.t | LocalDef of Names.Name.t * Constr.t * Constr.t Originally, named-context was represented as: Context.named_context = Names.Id.t * Constr.t option * Constr.t Now it is represented as: Context.Named.t = LocalAssum of Names.Id.t * Constr.t | LocalDef of Names.Id.t * Constr.t * Constr.t Motivation: (1) In "tactics/hipattern.ml4" file we define "test_strict_disjunction" function which looked like this: let test_strict_disjunction n lc = Array.for_all_i (fun i c -> match (prod_assum (snd (decompose_prod_n_assum n c))) with | [_,None,c] -> isRel c && Int.equal (destRel c) (n - i) | _ -> false) 0 lc Suppose that you do not know about rel-context and named-context. (that is the case of people who just started to read the source code) Merlin would tell you that the type of the value you are destructing by "match" is: 'a * 'b option * Constr.t (* worst-case scenario *) or Named.Name.t * Constr.t option * Constr.t (* best-case scenario (?) *) To me, this is akin to wearing an opaque veil. It is hard to figure out the meaning of the values you are looking at. In particular, it is hard to discover the connection between the value we are destructing above and the datatypes and functions defined in the "kernel/context.ml" file. In this case, the connection is there, but it is not visible (between the function above and the "Context" module). ------------------------------------------------------------------------ Now consider, what happens when the reader see the same function presented in the following form: let test_strict_disjunction n lc = Array.for_all_i (fun i c -> match (prod_assum (snd (decompose_prod_n_assum n c))) with | [LocalAssum (_,c)] -> isRel c && Int.equal (destRel c) (n - i) | _ -> false) 0 lc If the reader haven't seen "LocalAssum" before, (s)he can use Merlin to jump to the corresponding definition and learn more. In this case, the connection is there, and it is directly visible (between the function above and the "Context" module). (2) Also, if we already have the concepts such as: - local declaration - local assumption - local definition and we describe these notions meticulously in the Reference Manual, then it is a real pity not to reinforce the connection of the actual code with the abstract description we published.

2016-01-11CLEANUP: kernel/context.ml{,i}Matej Kosik
The structure of the Context module was refined in such a way that: - Types and functions related to rel-context declarations were put into the Context.Rel.Declaration module. - Types and functions related to rel-context were put into the Context.Rel module. - Types and functions related to named-context declarations were put into the Context.Named.Declaration module. - Types and functions related to named-context were put into the Context.Named module. - Types and functions related to named-list-context declarations were put into Context.NamedList.Declaration module. - Types and functions related to named-list-context were put into Context.NamedList module. Some missing comments were added to the *.mli file. The output of ocamldoc was checked whether it looks in a reasonable way. "TODO: cleanup" was removed The order in which are exported functions listed in the *.mli file was changed. (as in a mature modules, this order usually is not random) The order of exported functions in Context.{Rel,Named} modules is now consistent. (as there is no special reason why that order should be different) The order in which are functions defined in the *.ml file is the same as the order in which they are listed in the *.mli file. (as there is no special reason to define them in a different order) The name of the original fold_{rel,named}_context{,_reverse} functions was changed to better indicate what those functions do. (Now they are called Context.{Rel,Named}.fold_{inside,outside}) The original comments originally attached to the fold_{rel,named}_context{,_reverse} did not full make sense so they were updated. Thrown exceptions are now documented. Naming of formal parameters was made more consistent across different functions. Comments of similar functions in different modules are now consistent. Comments from *.mli files were copied to *.ml file. (We need that information in *.mli files because that is were ocamldoc needs it. It is nice to have it also in *.ml files because when we are using Merlin and jump to the definion of the function, we can see the comments also there and do not need to open a different file if we want to see it.) When we invoke ocamldoc, we instruct it to generate UTF-8 HTML instead of (default) ISO-8859-1. (UTF-8 characters are used in our ocamldoc markup) "open Context" was removed from all *.mli and *.ml files. (Originally, it was OK to do that. Now it is not.) An entry to dev/doc/changes.txt file was added that describes how the names of types and functions have changed.
