Hello, i just submitted a code, which could help us greatly in having up-to-date and full OpenGL API coverage in Squeak.
This package extracts data directly from spec files, used by OpenGL folks for generating C headers (gl.h / glext.h etc). So it is 100% correct. Parsing these files is much easier than C headers. There's also a lot of additional data , which helps to automatically categorise the methods and generate correct callout code. The parsed data can be later used for generating an FFI/Alien OpenGL callout code with full coverage of all existing extensions. And you don't need to keep this package in image after you done generating the code. Or, it can stay, just make sure that you prune all parsed data by issuing: GLAPIData reset. The sources for parsing is located at: http://www.opengl.org/registry/#specfiles Place all *.spec and *.tm files into a single directory, and then issue: GLAPIData parseAll: (FileDirectory on: 'your/path'). There is an example, how to generate an FFI callout methods. Use: GLAPIData gl generateFFIMethodsInto: (FileStream newFileNamed: 'gl.st') forClass: 'OpenGL' Then, you can file-in the generated code right into your image: (FileStream oldFileNamed: 'gl.st') fileIn The resulting file is about 700kbytes big, having methods like: !OpenGL methodsFor: 'EXT_framebuffer_multisample' stamp: 'Igor.Stasenko 4/14/2010 05:22'! glRenderbufferStorageMultisampleEXT: target with: samples with: internalformat with: width with: height "This method was automatically generated from OpenGL specs" "See http://squeaksource.com/OpenGLSpecs for details" <apicall: void 'glRenderbufferStorageMultisampleEXT' (GLenum GLsizei GLenum GLsizei GLsizei) > ^ self externalCallFailed P.S. I plan to use this data directly by native code, in a way like: glTexCoord2hNV: s with: t <primitive: 'primitiveNativeCall' module: 'NativeBoostPlugin'> ^ self glAPICall: 'glTexCoord2hNV' since i don't need a type data placed in method. I guess, Alien could use similar approach. -- Best regards, Igor Stasenko AKA sig. _______________________________________________ Pharo-project mailing list [email protected] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project
