Extension:RegexFunctions/ja

The RegexFunctions extension provides regular expression based parser functions.

使用法
As of now, this extension defines three parser functions, rmatch, rsplit, and rreplace


 * string (必須): The text the function uses for the matching.
 * pattern (必須): The regular expression to use on the text.
 * return (必須): What to return if the match was successful. $# and \# contain the captured text, and $$# and \\# contain the offsets of that text. Use ${#}# or \{#}# if you want a group followed by another number.
 * notfound (省略可能): What to return if the match was not successful. Defaults to an empty string.
 * offset (省略可能): The offset in bytes to start the match at. Defaults to 0 (the beginning of the text).
 * notfound (省略可能): What to return if the match was not successful. Defaults to an empty string.
 * offset (省略可能): The offset in bytes to start the match at. Defaults to 0 (the beginning of the text).


 * string (必須): The text the function will split.
 * pattern (必須): The regular expression to use on the text. No text is captured.
 * piece (省略可能): The piece to return. Defaults to 0 (the first piece).

 * string (必須): The text the function will replace.
 * pattern (必須): The regular expression to use on the text.
 * replace (必須): The text to replace the matched text with. Both $# and \# will call the capturing groups, use ${#}# or \{#}# if you want a group followed by another number.

 * How many functions are allowed per page. Default is 10, but it is recommended that it is set above 3 for usability.
