Re: [Vala] Problem converting library
2009/5/16 Matías De la Puente mfpuente...@gmail.com: You have to use vala-gen-introspect only for Glib/GObject based libs. For non-Glib libraries you have to write the vapi file by hand. Take a look at this page http://live.gnome.org/Vala/ExternalBindings And you will see glib and non-glib based libs and at the bottom a tutorial for Glib/GObject based libs Matias Another trick could be mangling the headers until vala-gen-introspect understands them and then straighten the resulting file by hand. vala-gen-introspect has difficulties with macros like GAULFUNC.

Re: [Vala] Simple HTML viewer in genie syntax
It's so beautifully simple! The thing is though, I'm stuck on one thing and I was wondering if someone on this mail-list could advise a solution. I want to grey-out the forward and back buttons as-appropriate, and I have a update_buttons() method in the code, but I don't know how to call it when a window page changes. Gtk.Widget.sensitive = false Another problem is I would like to tell it to use a different font, especially to display antialiased. The Gtk.Widget.get_style () / set_style () methods might help.

Re: [Vala] Added kill and pid_t to posix.vapi
2009/3/6 Michael 'Mickey' Lauer mic...@vanille-media.de:
Added the IntegerType descriptor. Can we apply the attached patch then?
Maybe you could consider altering glib.vapi too,
because there, Pid is defined as:
[SimpleType]

public struct Pid {
}

[Vala] Feature-Question: Compiler-API / AST of vala exposed to the programming language?
Hi, I didnt look into the details of vala, but what is of great value (especially for tool support) is a standard compiler API and standard AST form of vala code so that every vala program can parse its own code and modify it. This is essential for IDE tools like automated refactoring and code generation. (And metaprogramming). Would be great if Vala had that from the beginning.

Re: [Vala] just a suggestion
I still have a long way to learn Vala. Since someone is successfully using Vala in a number of projects I think they already have a good knowledge of common pitfalls, best practices and the like. Writing a book is one of the most efficient ways to learn. Believe me, that is how I learnt linux. Just start, it doesnt have to be perfact in the beginning. It can grow over time.
