anarchive - Inspired by this post by techb: http://evilzone.org/scripting-languages/tarpy/msg58234/#msg58234 (http://evilzone.org/scripting-languages/tarpy/msg58234/#msg58234). This is just a slight update from that thread adding fragile support for .rar files. But eventually I'd like to morph it into a tool that can do something like this:

:

$ anarchive -pattern "python" -o Python.Books.zip

Which would rip all files with "python" in the filename from every archive in the current directory, regardless of archive type, to a zip file (or whatever). I'm wondering, has this problem been solved before? I want something that will work the same across windows/linux/unix.

: (python)

#!/usr/bin/env python

# ^ leverage env for a universal hashbang
# USAGE: ./unarchive file1 file2 file3 ...

import tarfile
import zipfile
import subprocess
import os

#XXX desperate for error checking

class Rarfile:
    def __init__(self, fname):
        self.fname = fname

    def extractall(self, path):
        wd = os.getcwd()
        os.mkdir(path)
        os.rename(fname, os.path.join(path, fname))
        os.chdir(path)
        subprocess.call(["unrar", "x", fname])
        os.rename(fname, os.path.join(wd, fname))
        os.chdir(wd)


def guesstype(fname):
    return fname.split('.')[-1].lower()

def extract(fname, path="."):
    archivetype = guesstype(fname)

    if archivetype == "zip":
        archive = zipfile.ZipFile(fname, 'r')
    elif archivetype == "rar":
        archive = Rarfile(fname)
    else:
        archive = tarfile.open(fname, "r:*")

    archive.extractall(path)

if __name__ == "__main__":
    import sys

    files = sys.argv[1:]
    for fname in files:
        path = fname.split(".")[0]
        print("Extracting %s" % (fname)) # Treat print as a function, env might
        extract(fname, path)             # find python3 instead of python2.

From the project title I thought you were making an archive with anarchy related things (like bomb recipes, stories and such xD).

using .find() will probably do the job for you:

Heh, nothing that exciting...


Ragehottie, I'm actually more interested in hearing if there is something out there that does this already. Btw, is your avatar a stylized swastika?

I believe so. With a few simple scripting you can make a script around 7z:

:

7z x archive "path/to/file/inside/archive"

Ahh, for some reason I thought that was a windows-only graphical program. A wrapper around 7z will be much better & easier, thanks.
