There is an issue in Genie trying to invoke any method named foreach.
foreach is a keyword in vala to iterate over sequences.
But, Genie uses the more pythonic approach of using the for keyword:
for item in container do ....
foreach is not a keyword in Genie, and it has no usage.
However, Genie reserves the word in the parser, and when any method
called for each is invoked, an error occur. For example:
$ cat test.gs
def f(taglist: Gst.TagList, tag_name: string)
return
init
var L = new Gst.TagList()
L.foreach(f)
$ valac test.gs --pkg gstreamer-0.10
test.gs:7.11-7.17: error: syntax error, expected identifier
L.foreach(f)
And the same happen for any method named foreach.
I already raised a bug:
https://bugzilla.gnome.org/show_bug.cgi?id=607884
With a patch to remove foreach from the genie parser:
https://bugzilla.gnome.org/attachment.cgi?id=152102
Because of this issue, Genie can't practically use containers
like GstTagList, HashTable, Datalist and so on.
