Neodym - Unique Modern shader language compiling to GLSL shader

---

What is Neodym?

Neodym is a new programming language. It can be compiled into GLSL shaders.

Important

Neodym shader language uses .neo file extension.

Note

For now, Neodym shader language compiler is written only in Java
You can use this code in Java:

String code = /* ... Code in Neodym shader language */

Neodym result = Neodym.compile(code);
String fragment = result.getFragmentShader();
String vector = result.getVectorShader();

And this code in Kotlin:

val code: String = /* ... Code in Neodym shader language */

val (fragment, vector) = Neodym.compile(code)

to compile get both fragment and vector GLSL shader representations as String

Why Neodym?

Neodym is just much more flexible and readable language rather than GLSL.

GLSL do have some annoying syntax flaws. So, we decided to fix them:

We have replaced

1	2	3	4
float	vec2	vec3	vec4
int	ivec2	ivec3	ivec4
bool	bvec2	bvec3	bvec4

by these types:

1	2	3	4
float	float2	float3	float4
int	int2	int3	int4
bool	bool2	bool3	bool4

Also, you can omit ; at the end of code statements.

You have no longer define version for each shader. It will automatically be compiled to #version 330, so

Examples

The shader might be optionally used with single vector statement to declare vector shader behaviour:

vector {
    /* Vector shader */
}

/* Fragment shader */

If there's no vector statement, then default vector shader is being used:

main {
    gl_TexCoord[0] = gl_MultiTexCoord0
    gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex
}

Thanks for everyone who will help us to contribute our project.

Note

Neodym uses Lombok annotation processor in code
