anixon Posted May 3, 2010 Share Posted May 3, 2010 This one has got me stumped. The simply question is how do you convert a string to an array where the delimiter is a number of characters not " " or "|" etcThis could be the string:$TestMessage = "Now is the time for all good men to come to the aid of the party Now is the time for all good men to come to the end of the party" In this case the split was a maximum of 33 characters provided character 33 is equal to a space otherwise incremented by -1 until the first space is found and then [2] is processed from that character position using the same rules until the end of the string. [0] 2[1] Now is the time for all good men[2] to come to the aid of the party[3] Now is the time for all good men[4] to come to the aid of the partyHelp is always appreciated Ant..

jchd Posted May 3, 2010 Share Posted May 3, 2010 (edited) You could use StringRegExp to split on a fixed number N of characters, even if that number may need to be increased until the next whitespace.There will be a problem however if the tail of the string split that way contains less than N characters (no match in this case). If this can occur, the best choice will be to perform the split by character-by-character examination.Edit: your examples mis-counts. Applying your 33+ chars rule, we get the following split:Now is the time for all good men to come to the aid of the party Now is the time for all good men to come to the end of the partyAnd than can be done with a regexp, contrary to what I thought at first (using a strict rule), even with a short final tail.$res = StringRegExp($str, "(.{33,}?\s|.*)", 1) oops, wrong, all wrong!Try instead:#Include <Array.au3> Local $str = "Now is the time for all good men and women to come to the aid of the political_party_which_has_a_long_name Now is the time for all good men to come to the end of the party" Local $res = StringRegExp($str, "(.{33,}?(?:\s)|.+)", 3) _ArrayDisplay($res)Sorry for multiple edits!

jchd Posted May 4, 2010 Share Posted May 4, 2010 Again I apologize for editing my own errors multiple times while you were reading. The last change was making the separator whitespace (can be space, tab, cr) not captured, so that your strings don't end with space. If you need any adjustment, you know where to chime (when being another story!). This wonderful site allows debugging and testing regular expressions (many flavors available).
