That's because HashMap has no iterator() method, then vala uses the
size()/get() iterator mode. It's intended to work like that but absolutely
counter intuitive.

[Vala] [ANNOUNCE] Libgee 0.7.4 - GObject collection library
We are very pleased to announce version 0.7.4 of Libgee, the GObject collection library. Libgee 0.7.4 is now available for download at: http://download.gnome.org/sources/libgee/0.7/ Also please note that now Libgee has its own mailing-list http://mail.gnome.org/mailman/listinfo/libgee-list and its own #gee IRC channel. New in 0.7.4 * Remove *_impl methods * Move virtual methods to interfaces * Future-proof the ABI by adding reserved v-table members * Add read_only to Map.Entry Libgee is a collection library providing GObject-based interfaces and classes for commonly used data structures. Libgee provides the following interfaces: * Traversable o Iterable + Collection # List * BidirList # Set * SortedSet o BidirSortedSet # MultiSet # Queue * Deque + Map # SortedMap * BidirSortedMap o Iterator + BidirIterator # BidirListIterator + ListIterator # BidirListIterator * MultiMap The ArrayList, ArrauQueue, ConcurrentLinkedList HashSet, HashMap, HashMultiSet, HashMultiMap, LinkedList, PriorityQueue, TreeSet, TreeMap, TreeMultiSet, and TreeMultiMap classes provide a reasonable sample implementation of those interfaces. In addition, a set of abstract classes are provided to ease the implementation of new collections. Around that, the API provide means to retrieve read-only views, efficient sort algorithms, simple, bi-directional or index-based mutable iterators depending on the collection type. Libgee is written in Vala and can be used like any GObject-based C library. It's planned to provide bindings for further languages.

[Vala] foreach / Gee.Tree/HashMap
Hello,
I was running into an issue with Gee Maps and was wondering if this is
intended behaviour. Here's a minimal sample:
var map = new HashMap();
map[1] = "first";
map[2] = "second";
foreach (var value in map) {
stdout.printf((value ?? "null") + "\n");
}
stdout.printf("--\n");
foreach (var entry in map.entries) {
stdout.printf((entry.value ?? "null") + "\n");
}
The resulting output is:
null
first
--
first
second
The first loop seems to start at the non-existing key 0. Adding map[0] =
"test" seems to confirm that:
test
first
second
--
test
first
second
"Gaps" in the map-keys produce similar issues. Looks like a bug to me,
but I thought I'd ask here first.
Regards,
Dennis

[Vala] Bug 679876 - GObject Introspection has no support for Vala's classes and interfaces
Could any one check this bug? I think this is a problems in GLib/GObjectIntrospection, but maybe a problem in C code generated by Vala. -- Trabajar, la mejor arma para tu superación "de grano en grano, se hace la arena" (R) (en trámite, pero para los cuates: LIBRE) ___ vala-list mailing list vala-list@gnome.org https://mail.gnome.org/mailman/listinfo/vala-list
[Vala] [ANNOUNCE] Vala 0.17.5 - Compiler for the GObject type system
We are pleased to announce version 0.17.5 of Vala, a compiler for the GObject type system. Vala 0.17.5 is now available for download at: http://download.gnome.org/sources/vala/0.17/ Changes since 0.17.4 * Support subclassing of GLib.Source. * Switch pango bindings to .gir. * Add gstreamer-1.0 core bindings. * Add gst-plugins-base-1.0 bindings. * Add gobject-introspection-1.0 bindings. * Bug fixes and binding updates. Vala is a programming language that aims to bring modern programming language features to GNOME developers without imposing any additional runtime requirements and without using a different ABI compared to applications and libraries written in C. valac, the Vala compiler, is a self-hosting compiler that translates Vala source code into C source and header files. It uses the GObject type system to create classes and interfaces declared in the Vala source code.
