Allows simplified access to files in nested archives.

Example

Given an archive placed in /tmp/foobar/foo.tar with this structure:

foo.tar
    - foo1
    - foo2
    - bar.tar
       - bar1
       - bar2
       - foo3.tar.gz
            - foo4
            - foo5
       - foo6.tar.gz
            - foo7
            - foo8
    - abc/
       - def
       - ghi

This library will allow reading the contents of the files in this nested archive in the following "seamless" manner:

import nestedarchive

nestedarchive.get("/tmp/foobar/foo.tar/foo1")
nestedarchive.get("/tmp/foobar/foo.tar/abc/def")
nestedarchive.get("/tmp/foobar/foo.tar/bar.tar/bar1")
nestedarchive.get("/tmp/foobar/foo.tar/bar.tar/foo3.tar.gz/foo4")

Globs are also supported - all matches are tried until one is found that (eventually) contains the expected file, e.g.:

- nestedarchive.get("/tmp/foobar/foo.tar/bar.tar/foo*.tar.gz/foo7")

Will first silently try foo3.tar.gz and fail because it does not contain foo7, then it will try foo6.tar.gz and succeed because foo6.tar.gz contains foo7

If you want to get all files matching a glob, use get_all instead. get_all does not support a mode parameter, it always returns binary file data.

You can also access a URL instead of a local file path:

archive = nestedarchive.RemoteNestedArchive("https://example.com/archive.tar")
content = archive.get("/nested/path/file.txt")
