demultipart 0.2

Overview

MIME messages can be useful as cheap archives: unlike zipfile/tarfile standard modules, email.mime.multipart does not require a full-functional file to create an archive. MIME messages lack the ability to seek to a given file efficiently (much like tar), they have no standard compression (but it can be handled independently anyway), and lack a standard tool to extract them.

Inspired from python’s email examples .

Usage

Extract to directory $PWD/some

$ demultipart /path/to/some.multipart

Any number of multipart files can be specified, they will be extracted in provided order in their own directories.

Tries to prevent escaping extraction directory, but not tested on Windows.

Skips input file if extraction directory already exists.

TODO

• Provide compatibility with standard CLI archive manipulation tools (tar, unzip…) so GUI can wrap this command too.

• Maybe add multipart creation support.
