Re: [Vala] Rv: C to Vala
Doing some research, i found something relevant: http://razum.si/automagical/ It's not the same, but uses the same principle i've thought, declaring some rules about when finding a class declaration, translate; etc. Shouldn't be that hard, for a good declarative programmer (i'm not one, not even a coder). No bytecode needed, for i wasn't talking about decompiling. The idea is, given a C code with total use of GLib, can that be translated to Vala code? I wonder if there is some real problem holding back that possibility.

Converting arbitrary C code into Vala is possible, but unwieldy. A professor from my college days did a project that converts between various languages. It's quite complex, but amazingly all the conversion is done in XSLT.

Unlikely. You are confusing translate with transform. Please argue properly.

Re: [Vala] Rv: C to Vala
Once the Vala to C rules are defined, the inverse rules should work for C to vala, at least in a 80% - Mensaje original - De: Landon Blake Para: Mario Daniel Ruiz Saavedra CC: Enviado: Jueves, 20 de septiembre, 2012 12:47:10 Asunto: Re: [Vala] Rv: C to Vala It would be possible to take a program that translates English to Spanish and make it translate Spanish to English, but I think it would take some major tweaking. I'm sure the same concept applies to the Vala compiler.

Re: [Vala] Rv: C to Vala
valac takes Vala code, analyzes it, and generates C code accordingly. What hinders it from making it the other way (taking c code which heavily uses GLib, and turning it into Vala Code)? Also, whould prove correctness, as doing Vala to C and then C to Vala should produce similar code. - Mensaje original - De: Landon Blake Para: Mario Daniel Ruiz Saavedra CC: Enviado: Jueves, 20 de septiembre, 2012 11:38:53 Asunto: Re: [Vala] Rv: C to Vala Mario: I've just started using Vala, but I think I can take a stab at your questions. Vala is compiled to C, C is not compiled to Vala. Therefore, I don't think there would be an easy and automated way to convert C code into Vala code. Does that make sense?
