RE: [GD-General] Text file parsing

[Awen L. <ali...@ed...>]

I warmly recommend the XML option as a text file. Very smart, even if you're
using only its simplest functionnalitites (tag enclosure and hierarchy save
you a lot of further format maintenance time). And maybe there are now some
recommendations ready concerning Scene/Mesh 3D. If it could help you...

Objet : Re: [GD-General] Text file parsing


We use a structure very similar to ASE for our data definition files.
Writing the parser for it was about a couple hours.

If you're starting fresh, I would recommend using XML for structured text
files. You can use TinyXML to read them (use google to locate it).
