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. ### Timeline - 2020: aeosynth/bk repository created. - 2020-06-17: v0.2.0 release published. - 2021-03-27: v0.5.3 release published. - 2023-11-03: v0.6.0 release published. ### Related projects - epr is listed by the README as inspiration. - epy is compared in the README's feature table. - nnn is mentioned as an example file manager that can use bk --meta for preview integration. ### Sources - - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** bk - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - bk: normalized package name match | nixpkgs package indexes: pkgs/by-name/bk/bk/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - zypper - bk - 0.6.0-1.5: normalized package name match | openSUSE Tumbleweed package metadata: bk from https://download.opensuse.org/tumbleweed/repo/oss/repodata/be8d3611d25469107f32075a1697e69ec57a2b850b42348a658cc671ad5ec2b50760d02c3e59524d50da9a11d5be799bdaffba2e166e8ca8858512e3c0bd665d-primary.xml.zst | Terminal ePub reader | https://github.com/aeosynth/bk ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Productivity CLI packages](https://www.automicvault.com/pkg/productivity-cli-packages/) - Matched curated productivity category metadata from av.db. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [bookokrat](https://www.automicvault.com/pkg/brew/bookokrat/) - Shares av.db curated category or tags: cli, epub, productivity, terminal. - [abook](https://www.automicvault.com/pkg/brew/abook/) - Shares av.db curated category or tags: cli, productivity, terminal. - [aerc](https://www.automicvault.com/pkg/brew/aerc/) - Shares av.db curated category or tags: cli, productivity, terminal. - [alot](https://www.automicvault.com/pkg/brew/alot/) - Shares av.db curated category or tags: cli, productivity, terminal. - [alpine](https://www.automicvault.com/pkg/brew/alpine/) - Shares av.db curated category or tags: cli, productivity, terminal. - [amp](https://www.automicvault.com/pkg/brew/amp/) - Shares av.db curated category or tags: cli, productivity, terminal. - [bagels](https://www.automicvault.com/pkg/brew/bagels/) - Shares av.db curated category or tags: cli, productivity, terminal. - [bartib](https://www.automicvault.com/pkg/brew/bartib/) - Shares av.db curated category or tags: cli, productivity, terminal. - [circumflex](https://www.automicvault.com/pkg/brew/circumflex/) - Local package facts share a topical domain.
