[Vala] Simpler RE: embedding c code snippet in vala source.

You can probably simplify it and perhaps make it less offensive by getting rid of the C parsing for symbol names and try another way. For my work on compact classes vmt expressions etc, I implement it as a macro body; if you implement the snippet as a macro body it and pass in the vala paramete

Hi, You can take a look at samples on the Vala main page : http://live.gnome.org/Vala#head-9c728d151a2a0483d4f3b5837e5b545df9d8499d If you want more informations about gtk and glib ecosystem, look at : http://library.gnome.org/devel/references or with devhelp (which is better) with the right docu

[Vala] Question on Documentation and tutorials.

Hello, I just wanted to start by saying that I really do appreciate all the work that you do here on vala and I am very excited for the completion of this language and it's tools. As such I am interested in learning vala, however I have had a hard time with the documentation. I have looked through

Surely it's OK for VAPI files whose purpose is to integrate with C anyway; and certainly preferable to having to ship an extra vapi .h file with inline function or macro definitions... I think its great. I prefer the name cexpression to snippet, I use such things in my compac class virtual met
