App::moduleshere - copy modules(.pm) to cwd or somewhere
mhere Carp # copy Carp.pm in @INC to cwd mhere -r Carp # copy Carp and all under it. mhere Carp CGI # copy both Carp.pm and CGI.pm APP_MODULES_HERE=outlib mhere Carp # copy to outlib dir in cwd mhere -l outlib Carp # ditto APP_MODULES_HERE=/tmp/ mhere Carp # copy to /tmp/ mhere -l /tmp/ Carp # ditto
This small script(
mhere) helps you copy modules to somewhere you like. The precedence order is:
APP_MODULES_HERE and cwd. By default, it will copy to cwd.
It's first written when I tried to trace a bug in one of my modules which led me to another module(let's call it
Foo here) in
So I ran
perldoc -l Foo to find its path, edited it to add more debug info, forced save it(happy that I had the write permission), then reproduced the bug to go on debugging, and so on.
After fixed the bug, I was happy and decided to do something else, I almost forgot that I changed
Foo before! (believe me, I totally forgot it a couple of times) So I switched to
Foo, reversed all changed I've made, and forced save it again.
That was a bad experience so I decided to make a new approach. that is, to copy relative modules to current working directory and make changes there. after all done we can just remove it with a clean, untouched
@INC. The new one is better, at least for me, wish it can help you too :)
