Detailed Description

Creates compiled PHP code from templates to speed up template usage.

Various optimizations that can be done are:

Data:

  • Is constant, generate static data
  • Is variable, generate direct variable extraction
  • Has operators
  • Has attributes

Attributes:

  • Is constant, generate static data

Operators:

  • Supports input
  • Supports output
  • Supports parameters
  • Generates static data (true, false)
  • Custom PHP code
  • Modifies template variables, if possible name which ones. Allows for caching of variables in the script.

Functions:

  • Supports parameters
  • Supports children (set? no, section? yes)
  • Generates static data (ldelim,rdelim)
  • Children usage, no result(set-block) | copy(let,default) | dynamic(conditional, repeated etc.)
  • Children tree, requires original tree | allows custom processing
  • Custom PHP code
  • Deflate/transform tree, create new non-nested tree (let, default)
  • Modifies template variables, if possible name which ones. Allows for caching of variables in the script.
