I have heard perl is a good language at doing regex but i am a bit confused at the characters that requires escaping

I tested the code on http://regexlib.com/RETester.aspx and got the result I want

//home/dev/abc/code/hello/world.cpp#1
//home/dev/((.*?)/[^/]+).*#

Match   $1  $2
//home/dev/abc/code/hello/world.cpp#    abc/code    abc

However, I am not quite sure how do i translate this to perl code

I tried,

\/\/home\/dev\/\(\(\.\*\?\)\/\[\^\/\]\+\)\.\*\#

and

\/\/home\/dev\/((.*?)\/[^\/]+).*\#

and both failed

Don't you think the escaping makes the regex very unreadable? Am i using something wrong?
