5. 7.2 scripts/coder_format/coder_format.inc \coder_exec_processors()

Execute special tasks on source code.

This function works similar to the Drupal hook and forms system. It searches for all defined functions with the given prefix and performs a preg_replace on the source code for each of these functions.

Processor functions are defined with a associative array containing the following keys with the corresponding values: #title A human readable text describing what the processor actually does. #search The regular expression to search for. #replace The replacement text for each match.

Optional definitions: #debug Set this to true to directly output the results of preg_match_all and exit script execution after this processor.

Parameters

string $code: The source code to process.

string $prefix: Prefix of the functions to execute.

Return value

The processed source code.
