Regular Expressions¶

(*UTF8) - Enables utf8 instead of ascii regular expression.

Modifiers¶

/g /G - Enables global match.
/i /I - Enables Case in-sensitive.
/S - Strips any control codes before matching.
/s - Enables single line match.
/m /M /c /C - Enables multi line match.
/x /X - Eliminates unescaped white space from the pattern.
/U - Enabled non greedy mode. (Tries to replace greedy patterns with non greedy patterns + > +?, * -> *?)

Differences between .NET and prce¶

AdiIRC translate some patterns from PRCE into .NET patterns.

++ -> + [:alnum:] -> a-zA-Z0-9 [:alpha:] -> a-zA-Z [:ascii:] -> \x00-\x7F [:blank:] -> \s\t [:cntrl:] -> \x00-\x1F\x7F [:digit:] -> 0-9 [:graph:] -> \x21-\x7E [:lower:] -> a-z [:print:] -> \x20-\x7E [:punct:] -> !"#$%&'()*+,\-./:;<=>?@[\\\]^_`{|}~ [:space:] -> \s\t\r\n\v\f [:upper:] -> A-Z [:word:] - > A-Za-z0-9_" [:xdigit:] -> A-Fa-f0-9 \cc -> \x003 \co -> \x00F \cb -> \x002 \x\{([A-Fa-f0-9]{1,4})\} -> \uXXXX

\K is not available in .NET, use (<=abc)d instead.

These are not available and have no .NET counterpart:
code (?{…})
recursive (R), (R1), (R&name) (?R)
define (DEFINE).
