Member Function Documentation

compile()

TemplateParser::compile ( $templateName )

protected

Compile the Mustache template into PHP code using LightnCandy.

The compilation step generates both PHP code and metadata, which is also returned in the result. An example result looks as follows:

[
  'phpCode' => '...',
  'files' => [
    '/path/to/template.mustache',
    '/path/to/partial1.mustache',
    '/path/to/partial2.mustache',
  'filesHash' => '...'
]

The files entry is a list of the files read during the compilation of the template. Each entry is the fully-qualified filename, i.e. it includes path information.

The filesHash entry can be used to determine whether the template has changed since it was last compiled without compiling the template again. Currently, the filesHash entry is generated with FileContentsHasher::getFileContentsHash.

Parameters

string

$templateName

The name of the template

Returns

array An associative array containing the PHP code and metadata about its compilation

Exceptions

Exception	Thrown by LightnCandy if it could not compile the Mustache code
RuntimeException	If LightnCandy could not compile the Mustache code but did not throw an exception. This exception is indicative of a bug in LightnCandy PhanTypeMismatchArgument
