OK I see, thanks Gil.
I think the main problem is I don't know much about regex.
I will re-learn them this day.
heh, relearning regexes will take a lifetime, not just one day! :)

Thanks John.
Those symbols made me crazy entirely.
As what you explained, some are metadata of regex, some are regular
characters, it's not clear to me, due to my poor knowledge on regex.
Yes I will learn them more.

Hi!
"m{ pattern }" is regular expression to parse log string.
It's equal to just "/ pattern /". Using different delimiter is

unescaped and reges is more
