Hi again guys, I've made a small update to the highlighter, it should now
work better with brackets in lookups, and it should also highlight the new
mouse button names of the SDL2 ports as correct; which are now MOUSELEFT
and friends as opposed to MOUSE1 and friends.
Anyhoo, I'd appreciate some tips and advice on the todo list items.
First there's the case of the reserved references, I can get $[numargs] to
highlight properly, but not $numargs, any ideas what I can do in this vein?
I'm assuming the <keyword> tag is attempting a match against the $ (or @ as
the case may be) as well.
secondly, I wish to add proper support for the shader commands; it's
essentially vanilla GLSL, only it has CubeScript sprinkled about to
generate significant parts of the shader; basically as though it's a shader
processing language.
The CubeScript witchcraft is used to generate code, and to take the place
of what would ordinarily be #ifdef and #define statements.
A basic shader with variants would typically look something like this.
myshader = [
shader 0 [myshader_@arg1] [
attribute vec4 vvertex;
void main()
{
@(if (strstr $arg1 "f") [ result [
gl_Position = vec4(0, 0, 0, 0);
]] [ result [
gl_Position = vvertex;
]])
}
] [
fragdata(0, fragcolor, vec4)
void main(void)
{
@(if (strstr $arg1 "p") [ result [
fragcolor = vec4(1.0, 0.0, 1.0, 1.0);
]] [ result [
fragcolor = vec4(1.0, 1.0, 1.0, 1.0);
]])
}
]
]
myshader "p"
myshader "f"
myshader "fp"
Would I be able to do this by leveraging the existing GLSL file for my
uses, or will I be best served by making a tailored highlighter myself for
the GLSL sections?
