Hi *,
i stumbled on what seems to be a bug in std.regexp: It is incredibly
slow using the following pattern:
RegExp("^\\s+(\\d+)\\s+(\\d+)\\s+\\w+\\s+(\\w+)\\s+\\S+\\s+\\S+\\s+\\S+\\s+\\S+\\s+\\S+\\s+(.*)\r?\n?$")
I don't really get the regexp code, so i can't debug it myself, but i
have a PHP (!!) script that executes the same regexp in milliseconds.
I attached code to test it, can someone please confirm?
Thanks,
Markus
PS: Is there a quick way to fix this or are there bindings for other
RegExp libs that i can use (Linux and Windows required) - i need to fix
my program soon :) atm i'm looking for workarounds (splitting it into
small regexps).
This is a common problem with some regex designs. Java has (or had) the
same problem. I don't know if its fixable, you may want to try Tango's
regex package.
