calibre

This is a community package of calibre, maintained independently and unaffiliated with the calibre project. It repackages the official upstream Linux binary bundle unmodified, and follows upstream releases automatically.

calibre is a free and open-source e-book library manager. You can use it to catalog your books, fetch metadata for them automatically, convert them from and to all the various e-book formats, send them to your e-book reader devices, read the books on your computer, edit the books in a dedicated e-book editor and even make them available over the network with the built-in Content server. You can also download news and periodicals in e-book format from over a thousand different news and magazine websites.

• Library management: organise a collection of any size with custom columns, tags, saved searches and virtual libraries.
• Format conversion between EPUB, AZW3, MOBI, PDF, DOCX, FB2, HTMLZ, TXT and more, with a full-text search index over the whole library.
• E-book viewer with annotations, highlights, bookmarks, dictionary lookup and Read aloud text-to-speech.
• E-book editor for EPUB and AZW3, with live preview, spell check, a report of errors and automated cleanup tools.
• Content server: read and manage the library from a browser or another device on the network.
• News download: build periodicals from over a thousand recipes and read them like any other book.

The E-book viewer and the E-book editor are exported as their own launchers. calibre's command-line tools are available too, for example flatpak run --command=ebook-convert com.calibre_ebook.calibre book.epub book.azw3 and the same for calibredb, ebook-meta, ebook-polish, calibre-server, fetch-ebook-metadata and calibre-debug.

Permissions: this package grants your home directory, because that is where a calibre library lives — it is created at ~/Calibre Library on first run, holds the book files themselves, and records their paths absolutely, so it needs persistent access rather than one file at a time through the portal. Access outside your home directory is not granted. A few optional capabilities are not granted by default; enable the ones you need with flatpak override:

• Send books to an e-reader over USB or MTP (Kindle, Kobo, PocketBook, ...): flatpak override --user --device=all --system-talk-name=org.freedesktop.UDisks2 com.calibre_ebook.calibre
• Keep the library on an external drive or another mount point: flatpak override --user --filesystem=/run/media/$USER com.calibre_ebook.calibre (use the path your system mounts removable media under)
