can be extended in many ways; you can add extra tags, filters, tests, operators, global variables, and functions. You can even extend the parser itself with node visitors.

Keep in mind the following type available when you want to extend Twig:

  • global: Helper object
  • function: Content generation
  • filter: Value transformation
  • tag: DSL language construct
  • test: Boolean decision
  • operator: Values transformation

Detailed documentation about extending twig is available here
