regl-shared-context v1.0.1

regl-shared-context

Share regl context variables in the same context

Install

$ npm install regl-shared-context

Usage

const shared = require('regl-shared-context')
const regl = require('regl')()
regl({
  context: shared.context({
    first() { return 'first' },
    second() { return 'second' },
    third() { return 'third' },
    output({first, second, third}) {
      return `${first} ${second} ${third}`
    },
  })
})({output}) => {
  console.log(output) // 'first second third'
})

Why ?

When context variables are computed, the parent scope context is exposed to dynamic properties. This module allows local context properties to be exposed and shared between each other without the need to create multiple regl commands.

API

shared.context(object: Object) -> Object

This function accepts an object that should be used for the context property of the regl command constructor. It wraps a regl context object with accessors providing a shared regl context object. Properties are evaluated in the order in which they were defined.

const command = regl({
  context: shared.context({
    valueA: 123,
    valueB: ({valueA}) => valueB // 123
  })
})
