Scripts

Name: Anonymous 2012-01-04 12:16

Hey /prog/, what scripts have you been working on? I just made this simple on that I really needed to change all spaces in folders to underscores:


#/usr/bin/env python

import os

def main ():
    current_dir = os.getcwd ()
    current_dir_list = os.listdir (current_dir)

    for current_file in current_dir_list:
        os.rename (current_file, current_file.replace (" ", ""))

if __name__ == "__main__":
    main ()

Show us your latest scripts and feel free to rewrite mine and others in other languages!

def main ():
    current_dir = os.getcwd ()
    current_dir_list = os.listdir (current_dir)

    for current_file in current_dir_list:
        os.rename (current_file, current_file.replace (" ", "_"))

if __name__ == "__main__":
    main ()

Shit, I missed the underscore.

I downloaded a script to do that

if __name__ == "__main__":
    main ()


... Why?

I'm guess he doesn't want to have shit get reloaded everytime the program is ran. To put this in terms your monkey ass can understand, he wants to have the shit cached.

*I'm guessing*

He wants to be able to load the function into a Python shell or otherwise load the script as a Python module. main() isn't a very descriptive name for what the function does though.

And it will get loaded once. Geeze, why don't you just shut up and actually read the python docs instead of giving your own half assed description of what you think goes on.

You can't be very familiar with Python, or your English is bad, I can't tell.
If he had called the function without enclosing it in the if test then the function would be called every time he imported the module, it's typically used in small scripts such as >>1 to avoid just that.

Holy shit you're stupid. Have you ever written a non trivial Python script for any firm? I have. And in fact, the scripts I wrote run over several servers you moron. Anyways, what the OP did is correct. And what I described in correct. Now run along and go scrub another toilet.

>>11
What you described is correct, but what i described is also correct, if you seriously believe that OP was aiming for caching when writing that then you're incredibly dense, he did it so he could load the script as a module.

Name: kodak_gallery_programmer !!kCq+A64Losi56ze 2012-01-04 14:41

>>12
Well, someone asked why he was using main, and based on my programming experience, I provided a possible explanation.

Name: Anonymous 2012-01-04 14:45

>>13
It is a possible explanation, and I'm not going to argue, it's very useful information to have as well, however, it is extremely unlikely to be what OP was aiming for with this tiny script.

Is Kodak-san seriously not telling that guy that he's a mental midget who should scrub another toilet?

Are you going soft on us Kodak-san?

Name: Anonymous 2012-01-04 15:16

just ignore kodak, he doesn't know what he's talking about. and he's rude.

>>8 is correct: the if construct is a common python idiom (OP probably got it from a tutorial).

It does what Kodak says it does though.

if __name__ == "__main__":
    main()

It's a good habit, besides being useful when making modules, I don't like floating code.

Also, can anybody make a Perl or an Haskell version of that? Thanks.

Name: Anonymous 2012-01-04 15:42

And now the same thing in Perl...
rename $_, (($n = $_) =~ s/ /_/g, $n) for <*>

Name: Anonymous 2012-01-04 15:53

Does that only operate on directories or all files including directories?

Name: Anonymous 2012-01-04 15:58

>>19 And I'm guessing it operates on the current location of the script?

That's some small code.

Name: Anonymous 2012-01-04 16:07

Needs some error handling.  Didn't try running it.

module Main where

import System.Directory (renameFile, getDirectoryContents, getCurrentDirectory, doesDirectoryExist)
import Control.Monad (filterM)

replace :: Char -> Char -> String -> String
replace a b = map (\ x -> if x == a then b else x)

renamer :: FilePath -> IO FilePath
renamer x = let x' = replace ' ' '_' x in renameFile x x' >> return x'

main :: IO ()
main = getCurrentDirectory
   >>= getDirectoryContents
   >>= filterM doesDirectoryExist
   >>= mapM_ renamer

Hence why I work as a programmer and why >>16 works as a toilet scrubber.

Oh look Kodak shitting in another thread trying to look like a know-it-all while at the same time claiming it's worked with the big boys while the rest of you are just moron.


You know i'd rather have frozenvoid shitting it up with his EXPERT C than kodak being a nigger

I'm right though. Now shut up and try to learning something you uneducated jew.
