SYNOPSIS string *regexp(string *list, string pattern) DESCRIPTION Match the pattern pattern against all strings in list, and return a new array with all strings that matched. This function uses the same syntax for regular expressions as ed(): . Match any character. ^ Match begin of line. $ Match end of line. \< Match begin of word. \> Match end of word. x|y Match regexp x or regexp y. () Match enclosed regexp like a 'simple' one. x* Match any number (0 or more) of regexp x. [..] Match one of the characters enclosed. [^ ..] Match none of the characters enclosed. The .. are to replaced by single characters or character ranges: [abc] matches a, b or c. [ab0-9] matches a, b or any digit. [^a-z] does not match any lowercase character. \c match character c even if it's one of the special characters. If there is an error in the regular expression 0 will be returned. Remember that the character "\" has to be escaped with a "\" when written as a LPC string. EXAMPLE string strs; if (strs = regexp( ({"please, help me Sir John."}), "\\<help\\>.*\\<me\\>")) if (sizeof(strs) write("It matches.\n"); The regular expression will test the given string (which is packed into an array) if there is something like "help ... me" inside of it.
