Any OpengGL Shader Spelling Checker?

Question

I haven't found a tool for checking text spelling on OnpenGL shader for eclipse or another. Dealing with spelling errors on text based shaders like:

    protected String vertexShaderCode =
// This matrix member variable provides a hook to manipulate
// the coordinates of the objects that use this vertex shader
"uniform   mat4 uMVPMatrix; \n" + "attribute vec3 vPosition;  \n"
        + "void main(){               \n" +
        // the matrix must be included as a modifier of gl_Position
        " gl_Position = uMVPMatrix * vec4(vPosition, 1.0); \n" + "}  \n";

is a very time consuming task.

So, i wonder if somebody knows some kind of tool that helps with that.

Shader Designer from Typhoon Labs is a full-featured GLSL IDE. For quick checks/editing, I have also used this user defined language for Notepad++.

Hope this helps!

You should read your shader in as a text file. Then you can use your favorite word processor when editing your shader. If your talking plain spell checking. In which case A LOT of things will appear misspelled unless you add every word you allow (uMVPMatrix is not included in a standard dictionary).

Or if you want it to recognized initialized and non initialized variables you'd be better of writing a script which can find all initialized variables and contains a list of valid function names from OpenGL. Then checks to see if it can find anything it doesn't know from the two lists.

You say you were using Eclipse? What did you mean by other? If you meant another editor then for Visual Studio NShader is quite useful. While it doesn't provide auto-complete it does colour syntax to help spot problems.
