  4. 7.2 potx.inc \_potx_find_t_calls_with_context()

Detect all occurances of t()-like calls from Drupal 7 (with context).

These sequences are searched for: T_STRING("$function_name") + "(" + T_CONSTANT_ENCAPSED_STRING + ")" T_STRING("$function_name") + "(" + T_CONSTANT_ENCAPSED_STRING + "," and then an optional value for the replacements and an optional array for the options with an optional context key.

Parameters

$file: Name of file parsed.

$save_callback: Callback function used to save strings.

function_name: The name of the function to look for (could be 't', '$t', 'st' or any other t-like function). Drupal 7 only supports context on t(), st() and $t().

$string_mode: String mode to use: POTX_STRING_INSTALLER, POTX_STRING_RUNTIME or POTX_STRING_BOTH.
