Created page with "<pre> RegexUnescape( <expression> ) </pre> === Description === Remove any escapes from regular expression characters. RegexUnescape() takes a string and removes any backslash ..."

New page

<pre>
RegexUnescape( <expression> )
</pre>

=== Description ===

Remove any escapes from regular expression characters.

RegexUnescape() takes a string and removes any backslash in front of every character that is part of the regular expression syntax.

=== Parameters ===

==== expression ====

The string to use.

=== Return Value ===

Success: Returns the escaped string.

Failure: Returns empty string and sets @Error.

=== Remarks ===

If an escaped character in the string is not a Regexp compatible character then an empty string will be returned unmodified and the @Error will be set.

=== Example ===

<syntaxhighlight lang="sputnik">
// Obviously using @"" is the best way use Regexp strings
say @"(\w+)\s(\1)"; // Prints: (\w+)\s(\1)
say RegexEscape(@"(\w+)\s(\1)"); // Prints: \(\\w\+\)\\s\(\\1\)
say RegexUnEscape(RegexEscape(@"(\w+)\s(\1)")); // Prints: (\w+)\s(\1)
</syntaxhighlight>

Using @Error
<syntaxhighlight lang="sputnik">
say RegexUnEscape(@"\m");
if(@Error)
{
say "There was an error parsing";
say @ErrorMsg;
}
</syntaxhighlight>
