Hi, Please consider applying the attached patch. It adds support for using foreach with enums like this (and closes #624691):
> foreach (Enum e in Enum.all_values) {
> stdout.printf ("%s\n", e.to_string ());
> }

From f12ba46d78d1b3f448f8ef502b4bce970eced20f Mon Sep 17 00:00:00 2001 From: Sebastian Reichel <[email protected]> Date: Wed, 8 Feb 2012 07:06:44 +0100 Subject: [PATCH] add .all_values constant to enums returning all values enum.all_values can be used to get a constant enum[] with all values specified in the enum. This allows to use foreach with enums like this: foreach (Enum e in Enum.all_values) { stdout.printf ("%s\n", e.to_string ()); } --- vala/valaenum.vala | 12 ++++++++++++ 1 files changed, 12 insertions(+), 0 deletions(-) diff --git a/vala/valaenum.vala b/vala/valaenum.vala index eeabda9..5130cd7 100644 --- a/vala/valaenum.vala +++ b/vala/valaenum.vala @@ -44,6 +44,8 @@ public class Vala.Enum : TypeSymbol { private bool? _is_flags; + private InitializerList? all_constant; + /** * Creates a new enum. * @@ -53,6 +55,7 @@ public class Vala.Enum : TypeSymbol { */ public Enum (string name, SourceReference? source_reference = null, Comment? comment = null) { base (name, source_reference, comment); + generate_all_constant (source_reference); } /** @@ -65,6 +68,7 @@ public class Vala.Enum : TypeSymbol { values.add (value); scope.add (value.name, value); + all_constant.append (new MemberAccess (null, value.name)); } /** @@ -188,4 +192,12 @@ public class Vala.Enum : TypeSymbol { return !error; } + + private void generate_all_constant (SourceReference? source_reference = null) { + var type = new ArrayType (new EnumValueType (this), 1, source_reference); + all_constant = new InitializerList (source_reference); + var all = new Constant ("all_values", type, all_constant, source_reference); + all.access = SymbolAccessibility.PUBLIC; + add_constant (all); + } } -- 1.7.8.3
