code that orchestrates ebook conversion for project gutenberg

EbookConverter manages the creation and update of ebook assets for Project Gutenberg. It uses a postgres database to keep track of both ebook metadata and ebook files. the postgress database is managed by the libgutenberg package.

The cron-rebuild-files.sh script runs as a cron job, rebuilding 2100 books per day, so as to rebuild every book roughly once a month.

ebookconverter talks to the gutenberg database to build a list of ebookmaker jobs. These jobs require some metadata about the book, and a target file to process.

ebookconverter expects source files to be in numbered directories in a 'files' directory. The location of the files directory is given by the FILESDIR config parameter.

Config parameters should be set in a file at /etc/ebookconverter.conf or ~/.ebookconverter

ebookconverter has been tested on Python 3.6.7. It's not expected to run on python 2.7

pipenv install ebookconverter

The following directories should exist: - $PRIVATE/logs - $PRIVATE/logs/json - $PRIVATE/logs/json/backup - $PRIVATE/logs/notifications - $PRIVATE/logs/dopush - $PRIVATE/logs/dopush/backup

you can run these commands either by first entering a pipenv shell or on a single line using pipenv run <command> <args>

Rebuild one or more books ebookconverter --range=<start>-<finish> --build=all ebookconverter --range=<booknumber> --build=all ebookconverter --range=<booknumber> --build=all --validate

Reload metadata from a workflow json file (use with care, it will overwrite any metadata in the DB) reload_workflow <booknumber>
