From 1db568d3dc88d538f975377bb4d8d3eecd87872c Mon Sep 17 00:00:00 2001 From: Pierre-Marie Pédrot Date: Tue, 29 Aug 2017 19:05:57 +0200 Subject: Making detyping potentially lazy. The internal detype function takes an additional arguments dictating whether it should be eager or lazy. We introduce a new type of delayed `DAst.t` AST nodes and use it for `glob_constr`. Such type, instead of only containing a value, it can contain a lazy computation too. We use a GADT to discriminate between both uses statically, so that no delayed terms ever happen to be marshalled (which would raise anomalies). We also fix a regression in the test-suite: Mixing laziness and effects is a well-known hell. Here, an exception that was raised for mere control purpose was delayed and raised at a later time as an anomaly. We make the offending function eager. --- interp/constrextern.mli | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'interp/constrextern.mli') diff --git a/interp/constrextern.mli b/interp/constrextern.mli index ffa891c50..593580fb7 100644 --- a/interp/constrextern.mli +++ b/interp/constrextern.mli @@ -23,9 +23,9 @@ open Misctypes (** Translation of pattern, cases pattern, glob_constr and term into syntax trees for printing *) -val extern_cases_pattern : Id.Set.t -> cases_pattern -> cases_pattern_expr -val extern_glob_constr : Id.Set.t -> glob_constr -> constr_expr -val extern_glob_type : Id.Set.t -> glob_constr -> constr_expr +val extern_cases_pattern : Id.Set.t -> 'a cases_pattern_g -> cases_pattern_expr +val extern_glob_constr : Id.Set.t -> 'a glob_constr_g -> constr_expr +val extern_glob_type : Id.Set.t -> 'a glob_constr_g -> constr_expr val extern_constr_pattern : names_context -> Evd.evar_map -> constr_pattern -> constr_expr val extern_closed_glob : ?lax:bool -> bool -> env -> Evd.evar_map -> closed_glob_constr -> constr_expr -- cgit v1.2.3
