Strings in code

[JohnOne]

I was thinking about starting a small project, but when weighing up what would be needed, one of the requirements would be to find and replace all strings in an AutoIt script, and the more I thought about it, the more difficult and complex it seemed, and I'd have absolutely no chance of creating a regex pattern for something like that.

" 'strings like this for example' ", and worse "these one's".

I've had a quick unsuccessful search, does anyone know if one exists?

#Include <Array.au3>

$str = "MsgBox(64, 'Title', 'My ''test''')&, '''test'' My' &, 'M ''test'' y' ; $var = '"
$str &= @CRLF & 'MsgBox(64, "Title''s", ''test'') & ""'
$str &= @CRLF & '"these one''s"'
$str &= @CRLF & '" ''strings like this for example'' "'


$aOut = StringRegExp($str, '(''(?:[^''\r\n]*(?:'''')*[^''\r\n]*)*?''(?!'')|"(?:[^"\r\n]*(?:"")*[^"\r\n]*)*?"(?!"))', 3)
ConsoleWrite($str & @CRLF)
_ArrayDisplay($aOut)

Replace strings to what exactly?

That's quite great.

Thank you.

Shame it grabs strings from comments, but suppose they could be stripped first.

Variables.

[guinness]

Look at my Script Parsing thread for removing comments beforehand.

Cheers guinness.

The regexp part is tricky. When replacing multiple strings, it's essential to replace the longest strings first to avoid replacing part of a longer string by mistake. I don't know if there are many other functions to sort by length, but I wrote one if it's any use _ArraySortByLen(). Link

Good point, cheers czardas.
