Making a custom render type with a custom shader requires a number of things to exist at once:

1. A ShaderInstance which references your shader json. The RegisterShadersEvent lets you define a ShaderInstance, and has a callback for when the shader is fully loaded from disk.
2. A ShaderStateShard with a supplier that returns the ShaderInstance. The supplier exists so that shaders can reload themselves when you change resourcepacks or do a F3+T reload.
3. A RenderType which uses the ShaderStateShard as its shader state.
4. A shader json, which declares the shader properties and points to the shader programs (vsh and fsh).
5. A vertex shader program, which describes how the vertex data is transformed before passing into the rasterizer and being turned into pixels.
6. A fragment shader program, which describes how the interpolated values from the vertices get turned into color values before being passed into the output blending stage.

Note: The vanilla logic does not normally allow namespaces in the shader

These examples are presented in an attempt to show how each coding styles attempts to or does not attempt to isolate side-effects. There are only 2 semantic elements in a barebone "Hello World" implementation:

• Invocation of console.log
• Declaration of HELLO_WORLD

Since every coding style can abstract away data into a parameter or variable, there is no point for us to show that. All implementations assume HELLO_WORLD is a constant that is always inlined. This way it reduces the variations we need to present. (To make an anology, if we were to implement incrementByOne, would we need to inline the number 1 or pass it in as parameter?)

CAVEAT/LIMITATION: All implementations also assume console is static global. In case of functional programming, console.log is asumed to be a function that can be passed around without further modification. (This is not the case in the browser, but that can be resolved with console.log.bind(console))

So you have a javascript function.

function func () {}

It accepts a value.

function func (param) {}

What is that sound? Did someone leave the tap on? Is there a leak somewhere?

drip, drip, drip

Maybe it's raining. It hasn't rained in a long time. She remembers one rainy day in particular, from before she planted her wishing tree under which she weeps. She remembers the smell of sweat, clinging cloth to skin, streaming down a forehead. The all-too-red blush on cheeks. Wheezing and coughing and puffing, creaking planks and a leaky roof (her father will fix it, surely).
