Collection of working samples

Extracting words:

$a = StringRegExp("Some words to extract", "[\w]+", 3)
_ArrayDisplay($a, "Extracted words")

Extracting lines:

$a = StringRegExp("Some words to extract", "(.*)", 3)
_ArrayDisplay($a, "Extracted lines")

Extracting sentences:

Tested, verified, and working on pretty much any sentences... Needs work on words spelled with punctuation symbols, such as Mr., Mrs. Can be handled prior to regex testing by changed to mister and misses.

-JRowe

Local $a 
$a = StringRegExp($data, "(['""\w\d\(\),\;\:\-\@\&\s]+(?:.\w+)?+[\.\!\?])", 3)
_ArrayDisplay($a, "Extracted lines")

AutoIt normalize variable declarations:

Collect Global, Local and Dim statements in selected code and create declaration code to be inserted as a group in the file TODO: Not tested!

Local $a 
$a = StringRegExp($data, "\s*(Global|Local|Dim)(\s+$\w+)", 3)
_ArrayDisplay($a, "Extracted lines")
