history

Project history and usage

bk is a terminal EPUB reader written in Rust. Its README emphasizes a cross-platform single binary with instant startup, EPUB 2/3 support, Vim bindings, incremental search, and bookmarks.

Project history

The repository was created in 2020 and published early 0.x releases the same year. The release history includes v0.2.0 in June 2020, v0.5.3 in March 2021, and v0.6.0 in November 2023.

Adoption history

The input package-manager data lists Homebrew, Nix, and openSUSE packaging. The README's primary upstream install path is cargo install bk, so system packages are convenience packaging around a Rust CLI tool.

How it is used

Users run bk with an EPUB path, or without a path to reopen the most recent EPUB. Options include metadata output, starting with the table of contents open, and setting display width and colors.

The README compares bk with epr/epy, highlighting no runtime dependencies, wide-character support, incremental and multi-line search, links, themes, and the --meta switch for file-preview integration.

Why package nerds care

bk is a small but tidy example of Rust single-binary packaging in the terminal-media niche: no Python/curses runtime stack, quick startup, and enough EPUB support for keyboard-driven reading.

Its package appeal is strongest for users who want ebook reading to behave like the rest of their terminal workflow.
