I would like to bind file with common function to shaders, something like that:

circleSDF.fp.glsl is a file that contain a single function, to keep methods more reusable.

I would like to bind file with common function to shaders, something like that:

 <program name="vp" type="vertex" source="VertexByPass.vp.glsl" />
 
 <program name="fp" type="fragment" source="circleSDF.fp.glsl" />
 <program name="fp" type="fragment" source="013-the-merge.fp.glsl" />

circleSDF.fp.glsl is a file that contain a single function, to keep methods more reusable.

float circleSDF(vec2 st) {
 return length(st-.5)*2.;
}

now I clean my head, basically I'm asking if is possible to #include file using jxs file...

Asking again. Can we do #include statements in jxs. files?

When I use an #include I get "Invalid Directive: include".

I want to be able to reuse a library of SDF functions.

The support is via XML include tags, rather than #include directives. The gl3 launcher patch demonstrates how to use them.

GLSL include is supported in the gl3 engine. 

Thanks for the quick reply. I have it working now for me. However I noticed that if the shaders are in a subfolder the <include/> doesn't work. It can't find the included file. Only when the shaders(both .jxs and .glsl) are at the same level as the maxpat will it work. I'll adjust but I'm wondering if I'm missing something?

Update: I think I figured it out. only the <include/> file needs to be at the same level as the patch. You can collect shaders in a sub folder.
