From f9a4ca41bc1313300f5f9b9092fe24825f435706 Mon Sep 17 00:00:00 2001 From: Hugo Herbelin Date: Wed, 1 Feb 2017 15:56:45 +0100 Subject: Replacing "cast surgery" in LetIn by a proper field (see PR #404). This is a patch fulfilling the relevant remark of Maxime that an explicit information at the ML type level would be better than "cast surgery" to carry the optional type of a let-in. There are a very few semantic changes. - a "(x:t:=c)" in a block of binders is now written in the more standard way "(x:=c:t)" - in notations, the type of a let-in is not displayed if not explicitly asked so. See discussion at PR #417 for more information. --- ide/texmacspp.ml | 9 ++-- interp/constrexpr_ops.ml | 30 +++++++------ interp/constrexpr_ops.mli | 2 +- interp/constrextern.ml | 16 ++++--- interp/constrintern.ml | 32 +++++++------- interp/implicit_quantifiers.ml | 14 ++++-- interp/notation_ops.ml | 43 ++++++++++++------- interp/smartlocate.ml | 2 +- interp/topconstr.ml | 14 +++--- intf/constrexpr.mli | 4 +- intf/glob_term.mli | 4 +- intf/notation_term.mli | 2 +- intf/pattern.mli | 2 +- parsing/g_constr.ml4 | 14 +++--- plugins/decl_mode/decl_interp.ml | 7 +-- plugins/funind/glob_term_to_relation.ml | 73 ++++++++++++++++++-------------- plugins/funind/glob_term_to_relation.mli | 2 +- plugins/funind/glob_termops.ml | 60 ++++++++++++++------------ plugins/funind/glob_termops.mli | 2 +- plugins/funind/indfun.ml | 16 ++++--- plugins/funind/indfun_common.ml | 4 +- plugins/funind/indfun_common.mli | 2 +- plugins/funind/merge.ml | 16 +++---- plugins/ssrmatching/ssrmatching.ml4 | 4 +- pretyping/constr_matching.ml | 6 ++- pretyping/detyping.ml | 23 +++++----- pretyping/glob_ops.ml | 32 ++++++++------ pretyping/patternops.ml | 24 ++++++----- pretyping/pretyping.ml | 16 +++---- printing/ppconstr.ml | 18 ++++---- vernac/command.ml | 6 +-- vernac/record.ml | 2 +- 32 files changed, 280 insertions(+), 221 deletions(-) diff --git a/ide/texmacspp.ml b/ide/texmacspp.ml index e705e4e5a..e787e48bf 100644 --- a/ide/texmacspp.ml +++ b/ide/texmacspp.ml @@ -15,6 +15,7 @@ open Bigint open Decl_kinds open Extend open Libnames +open Constrexpr_ops let unlock loc = let start, stop = Loc.unloc loc in @@ -228,9 +229,10 @@ and pp_decl_notation ((_, s), ce, sc) = (* don't know what it is for now *) Element ("decl_notation", ["name", s], [pp_expr ce]) and pp_local_binder lb = (* don't know what it is for now *) match lb with -
