From 2c5eef988f11979175de6d1983bc533ce18b1095 Mon Sep 17 00:00:00 2001 From: Maxime Dénès Date: Wed, 2 Nov 2016 15:57:19 +0100 Subject: Fix various shortcomings of the warnings infrastructure. - The flags are now interpreted from left to right, without any other precedence rule. The previous one did not make much sense in interactive mode. - Set Warnings and Set Warnings Append are now synonyms, and have the "append" semantics, which is the most natural one for warnings. - Warnings on unknown warnings are now printed only once (previously the would be repeated on further calls to Set Warnings, sections closing, module requiring...). - Warning status strings are normalized, so that e.g. "+foo,-foo" is reduced to "-foo" (if foo exists, "" otherwise). --- library/goptions.mli | 14 ++++++++++---- 1 file changed, 10 insertions(+), 4 deletions(-) (limited to 'library/goptions.mli') diff --git a/library/goptions.mli b/library/goptions.mli index ca2df0710..3b3651f39 100644 --- a/library/goptions.mli +++ b/library/goptions.mli @@ -122,13 +122,19 @@ type 'a option_sig = { (** When an option is declared synchronous ([optsync] is [true]), the output is a synchronous write function.
