Features

• Directory hierarchy support

/etc/lib2opds.ini is used by default and options can be overridden via command line arguments.

Example of configuration file for Nginx:

location /library {
        alias /library-dir;
}

location /opds {
        auth_basic  "Library Area";
        auth_basic_user_file /etc/nginx/htpasswd;
        alias /opds-dir;
        index index.xml;
}

location /opds/covers {
        alias /opds-dir/covers;
}

Library location here is not protected with basic auth because of the bug in some e-book reader software.

Sidecar files

lib2opds detects sidecar files for the target e-book file and extracts metadata and cover from them.

For example, in case of some-book.epub e-book file lib2opds will try to check for some-book.info and some-book.cover files.

.info sidecar files are basically INI-format files:

[Publication]
title = 1984
authors =  George Orwell
description = Some summary here
language = en
issued = 1949
publisher = SomePublisher, Inc.
identifier = urn:isbn:9781443434973

.cover is just an image file.
