debugging - Why does Perl's quotemeta() function behave differently when under the debugger? -

-

I have been bitten by this small inconsistent debugger behavior. perl -d

$ perl -e 'under the print quotemeta ("/ a quotemeta () function behaves differently /

The output is \ / a \ / b / c , which is correct and as such copy-F comma . < / P>

Now, when under the debugger, the output becomes \\ / a \\ / b \\ / c . I thought that I'm using some core modules, Although the task was redefined in the form of a test, it seems that behavior happens when D CORE :: quotemeta () gives the same output.

Can anyone illuminate me?

Thank you! < / P>

quotemeta is a shotgun, to avoid all non-word characters For whether they require it or not, debugger is less heavy; cites those words for which it is needed (backslash, do not slash forwards.) More importantly, when you use the original When you print them, then compare them: 

  DB < 1 & gt; X colometa ('a / b / c') 0 'a \ \ / b \\ / c' db & lt; 2 & gt; P quoted ('a / b / c') a \ / b / c

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
