2020-12-09Using self-documenting argument names in two exceptions of cases.ml.Hugo Herbelin
Namely, WrongNumargInductive and WrongNumargConstructor.
2020-12-09Fixing support for argument scopes and let-ins while interning cases patterns.Hugo Herbelin
We also simplify the whole process of interpretation of cases pattern on the way.
2020-10-05Wish #12762: warning on duplicated catch-all pattern with unused named variable.Hugo Herbelin
An identifier starting with _ deactivates the warning. Co-authored-by: Jim Fehrle <jim.fehrle@gmail.com>
2020-03-18Update headers in the whole code base.Théo Zimmermann
Add headers to a few files which were missing them.
2019-11-21[coq] Untabify the whole ML codebase.Emilio Jesus Gallego Arias
We also remove trailing whitespace. Script used: ```bash for i in `find . -name '*.ml' -or -name '*.mli' -or -name '*.mlg'`; do expand -i "$i" | sponge "$i"; sed -e's/[[:space:]]*$//' -i.bak "$i"; done ```
2019-06-17Update ml-style headers to new year.Théo Zimmermann
2019-02-05Make Program a regular attributeMaxime Dénès
We remove all calls to `Flags.is_program_mode` except one (to compute the default value of the attribute). Everything else is passed explicitely, and we remove the special logic in the interpretation loop to set/unset the flag. This is especially important since the value of the flag has an impact on proof modes, so on the separation of parsing and execution phases.
2018-09-26Making cases.ml use state-passing instead of the evdref idiom.Pierre-Marie Pédrot
2018-09-10Moving part of pretyping dealing with ltac and renaming in new module GlobEnv.Hugo Herbelin
This module contains: - the former ExtraEnv in pretyping - a few functions to traverse binders in pretyping.ml and cases.ml - the part of pretyping dealing with genarg interpretation The dependency of pretyping in an interpretation of names as names of variables of identifier is now hidden in GlobEnv (no more explicit "lvar" management in pretyping.ml). Similarly for the interpretation of names as terms and for the interpretation of tactics-in-terms. We keep empty_lvar in Glob_ops for compatibility, even though it is a bit isolated there.
2018-02-27Update headers following #6543.Théo Zimmermann
2017-11-22[api] A few more minor deprecation notices.Emilio Jesus Gallego Arias
Note the problem with `create_evar_defs`.
2017-11-06[api] Move structures deprecated in the API to the core.Emilio Jesus Gallego Arias
We do up to `Term` which is the main bulk of the changes.
2017-11-06[api] Deprecate all legacy uses of Names in core.Emilio Jesus Gallego Arias
This will allow to merge back `Names` with `API.Names`
2017-10-25[general] Remove Econstr dependency from `intf`Emilio Jesus Gallego Arias
To this extent we factor out the relevant bits to a new file, ltac_pretype.
2017-09-28Efficient fresh name generation relying on sets.Pierre-Marie Pédrot
The old algorithm was relying on list membership, which is O(n). This was nefarious for terms with many binders. We use instead sets in O(log n).
2017-07-04Bump year in headers.Pierre-Marie Pédrot
2017-06-09A fix to #5414 (ident bound by ltac names now known for "match").Hugo Herbelin
Also taking into account a name in the return clause and in the indices. Note the double meaning ``bound as a term to match'' and ``binding in the "as" clause'' when the term to match is a variable for all of "match", "if" and "let".
2017-04-25[location] Remove Loc.ghost.Emilio Jesus Gallego Arias
Now it is a private field, locations are optional.
2017-02-14Merge branch 'master'.Pierre-Marie Pédrot
2017-02-14Definining EConstr-based contexts.Pierre-Marie Pédrot
This removes quite a few unsafe casts. Unluckily, I had to reintroduce the old non-module based names for these data structures, because I could not reproduce easily the same hierarchy in EConstr.
2017-02-14Making judgment type generic over the type of inner constrs.Pierre-Marie Pédrot
This allows to factorize code and prevents the unnecessary use of back and forth conversions between the various types of terms. Note that functions from typing may now raise errors as PretypeError rather than TypeError, because they call the proper wrapper. I think that they were wrongly calling the kernel because of an overlook of open modules.
2017-02-14Cases API using EConstr.Pierre-Marie Pédrot
2016-12-07Merge branch 'v8.6'Pierre-Marie Pédrot
2016-11-30Fix UGraph.check_eq!Matthieu Sozeau
Universes are kept in normal form w.r.t. equality but not the <= relation, so the previous check worked almost always but was actually too strict! In cases like (max(Set,u) = u) when u is declared >= Set it was failing to find an equality. Applying the KISS principle: u = v <-> u <= v /\ v <= u. Fix invariant breakage that triggered the discovery of the check_eq bug as well. No algebraic universes should appear in a term position (on the left of a colon in a typing judgment), this was not the case when an algebraic universe instantiated an evar that appeared in the term. We force their universe variable status to change in refresh_universes to avoid this. Fix ind sort inference: Use syntactic universe equality for inductive sort inference instead of check_leq (which now correctly takes constraints into account) and simplify code
2016-08-19Unify location handling of error functions.Emilio Jesus Gallego Arias
In some cases prior to this patch, there were two cases for the same error function, one taking a location, the other not. We unify them by using an option parameter, in the line with recent changes in warnings and feedback. This implies a bit of clean up in some places, but more importantly, is the preparation for subsequent patches making `Loc.location` opaque, change that could be use to improve modularity and allow a more functional implementation strategy --- for example --- of the beautifier.
2016-06-29Program: cleanup in cases, add optionsMatthieu Sozeau
Unset Program Generalized Coercion to avoid coercion of general applications. Unset Program Cases to deactivate generation equalities and disequalities of cases.
2016-04-27Revert "More abstraction in cases.mli."Hugo Herbelin
This reverts commit 975e2a05050c704161aca3fbac96376eeda6fb4a.

2016-04-27Fixing a "This clause is redundant" error when interpreting the "in"Hugo Herbelin
clause of a "match" over an irrefutable pattern.

2016-01-20Update copyright headers.Maxime Dénès
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.

2014-09-12Uniformisation of the order of arguments env and sigma.Hugo Herbelin
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.
2014-06-17- Fix the de Bruijn problem in check_projection for good :)Matthieu Sozeau
- Fix HoTT coq bug #80, implicit arguments with primitive projections were wrongly automatically infered.
2014-04-23Removing dead code, thanks to new OCaml warnings and a bit of scripting.Pierre-Marie Pédrot
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.
2013-11-02Fix compilation of pattern matching wrt variables: alias.aspiwack
Aliases (as clause) are a bit tricky. In Goal True, refine match 0 with | S n as p => _ | _ => I end Must produce the goal n:nat, p := S n : nat |- True However, in the deep branches: refine match 0 with | S (S n as p) => _ | _ => I end The alias is used to give a name to the variable of the first S : p:nat, n:nat |- True Before this patch, the goal would be p:nat, n:nat, p:=p : nat |- True Alias was used both to name the variable of the first S and to alias it. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17022 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-11-02Fix the compilation of pattern matching wrt to variables.aspiwack
Compilation of pattern-matching used to systematically introduce a dummy alias x:=x in the typing environment for each variable x in the patterns (except for purely variable patterns which correctly alias the term being matched). This interfered badly with the new refine implementation. To correct this I changed the "all variables" case of pattern-matching compilation to check whether the term currently being matched is a term introduced by the user or a subterm which is necessarily a variable. In the latter case, no alias is introduced. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17020 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-04-29Splitting Term into five unrelated interfaces:ppedrot
1. sorts.ml: A small file utility for sorts; 2. constr.ml: Really low-level terms, essentially kind_of_constr, smart constructor and basic operators; 3. vars.ml: Everything related to term variables, that is, occurences and substitution; 4. context.ml: Rel/Named context and all that; 5. term.ml: derived utility operations on terms; also includes constr.ml up to some renaming, and acts as a compatibility layer, to be deprecated. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16462 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-06-22Added an indirection with respect to Loc in Compat. As many [open Compat]ppedrot
were closed (i.e. the only remaining ones are those of printing/parsing). Meanwhile, a simplified interface is provided in loc.mli.
