* CLEANUP: switching from "right-to-left" to "left-to-right" function ↵Gravatar Matej Kosik2016-08-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | composition operator. Short story: This pull-request: (1) removes the definition of the "right-to-left" function composition operator (2) adds the definition of the "left-to-right" function composition operator (3) rewrites the code relying on "right-to-left" function composition to rely on "left-to-right" function composition operator instead. Long story: In mathematics, function composition is traditionally denoted with ∘ operator. Ocaml standard library does not provide analogous operator under any name. Batteries Included provides provides two alternatives: _ % _ and _ %> _ The first operator one corresponds to the classical ∘ operator routinely used in mathematics. I.e.: (f4 % f3 % f2 % f1) x ≜ (f4 ∘ f3 ∘ f2 ∘ f1) x We can call it "right-to-left" composition because: - the function we write as first (f4) will be called as last - and the function write as last (f1) will be called as first. The meaning of the second operator is this: (f1 %> f2 %> f3 %> f4) x ≜ (f4 ∘ f3 ∘ f2 ∘ f1) x We can call it "left-to-right" composition because: - the function we write as first (f1) will be called first - and the function we write as last (f4) will be called last That is, the functions are written in the same order in which we write and read them. I think that it makes sense to prefer the "left-to-right" variant because it enables us to write functions in the same order in which they will be actually called and it thus better fits our culture (we read/write from left to right).

* CLEANUP: Renaming "Util.compose" function to "%"Gravatar Matej Kosik2016-02-17
| | | | | | | | | | | I propose to change the name of the "Util.compose" function to "%". Reasons: 1. If one wants to express function composition, then the new name enables us to achieve this goal easier. 2. In "Batteries Included" they had made the same choice.

* Use open_utf8_file_in for opening files in the IDE. (Fix bug #2874)Gravatar Guillaume Melquiond2015-07-28
| | | | | | | | File system.ml seemed like a better choice than util.ml for sharing the code, but it was bringing a bunch of useless dependencies to the IDE. There are presumably several other tools that would benefit from using open_utf8_file_in instead of open_in, e.g. coqdoc.
* Getting rid of Exninfo hacks.Gravatar Pierre-Marie Pédrot2014-12-16
| | | | | | | | | | | | | | | | | | | | Instead of modifying exceptions to wear additional information, we instead use a dedicated type now. All exception-using functions were modified to support this new type, in particular Future's fix_exn-s and the tactic monad. To solve the problem of enriching exceptions at raise time and recover this data in the try-with handler, we use a global datastructure recording the given piece of data imperatively that we retrieve in the try-with handler. We ensure that such instrumented try-with destroy the data so that there may not be confusion with another exception. To further harden the correction of this structure, we also check for pointer equality with the last raised exception. The global data structure is not thread-safe for now, which is incorrect as the STM uses threads and enriched exceptions. Yet, we splitted the patch in two parts, so that we do not introduce dependencies to the Thread library immediatly. This will allow to revert only the second patch if ever we switch to OCaml-coded lightweight threads.

* 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

* 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

* The new ocaml compiler (4.00) has a lot of very cool warnings,Gravatar regisgia2012-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | especially about unused definitions, unused opens and unused rec flags. The following patch uses information gathered using these warnings to clean Coq source tree. In this patch, I focused on warnings whose fix are very unlikely to introduce bugs. (a) "unused rec flags". They cannot change the semantics of the program but only allow the inliner to do a better job. (b) "unused type definitions". I only removed type definitions that were given to functors that do not require them. Some type definitions were used as documentation to obtain better error messages, but were not ascribed to any definition. I superficially mentioned them in one arbitrary chosen definition to remove the warning. This is unaesthetic but I did not find a better way. (c) "unused for loop index". The following idiom of imperative programming is used at several places: "for i = 1 to n do that_side_effect () done". I replaced "i" with "_i" to remove the warning... but, there is a combinator named "Util.repeat" that would only cost us a function call while improving readibility. Should'nt we use it? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15797 85f007b7-540e-0410-9357-904b9bb8a0f7

* Unification: Added a heuristic to solve problems of the formGravatar herbelin2012-03-26
| | | | | | | | | | | | | | | | | | ?x[t1..tm] = ?y[u1..un] when ?x occurs in u1..un with no (easy) way to know if it occurs in rigid position or not. Such equations typically come from matching problems such as "match a return ?T[a] with pair a1 a2 => a1 end" where, a is in type "?A * ?B", and, in the branch, the return clause, of the form "?T[pair ?A ?B a1 a2]", has to be unified with ?A. This possible dependency is kept since commits r15060-15062. The heuristic is to restrict ?T so that the dependency is removed, leading to a behavior similar to the one existing before these commits. This allows BGsection15.v, from contrib Ssreflect, to compile as it did before these commits. Also, removed one function exported without true need in r15061. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15092 85f007b7-540e-0410-9357-904b9bb8a0f7

Concretely, this affects TACTIC EXTEND blocks of the form TACTIC EXTEND foo [ "bar" tactic_opt(tac) -> ... ] | [ "bar" constr_list(tac) -> ... ] where both rules parses "bar" alone but only the first rule must be registered in the atomic table, git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15046 85f007b7-540e-0410-9357-904b9bb8a0f7
