Godot: How does Godot 3.0 write 2D shader

[cjmxp]

Operating system or device - Godot version:

How does Godot 3.0 write 2D shader? Where does the new shader syntax get help documentation?

No documentation yet (as explained in the post about the alpha) but you can look here:
https://github.com/godotengine/godot/blob/772485cdb3a0b0003da6e174157680559fa2a59e/servers/visual/shader_types.cpp#L153

And maybe here too:
https://github.com/godotengine/godot/blob/e577c5b0705168177943fcdf9a0b66c1f8f864f3/drivers/gles3/shader_compiler_gles3.cpp

The error messages are better than on 2.x and has code completion too.

Basically, the shaders are now like:

shader_type canvas_item;

void vertex() {
}

void fragment() {
}

void light() {
}

in the same place.
You can find some examples in the demos repository (I think "screen space shaders" is working).
