Re: [Vala] GLib Command Line Parsing

[Émilien Tlapale <emilien tlapale com>]

Thanks!

I was missing the `const' qualifier. As const variables
need not to be put inside methods, i need to add static variables
or global ones to handle the arguments :(

Anyway, why in OptionContext's method :

public bool parse (out string[] argv) throws OptionError;

argv is out? Shouldn't it be a ref?
