Its README emphasizes a keyboard-oriented CLI experience: remembering the last book and per-file reading state, adapting to terminal resize, supporting EPUB3 text, opening embedded images, and providing simple dark and light color schemes. ### 项目历史 The GitHub repository was created in March 2019. The project kept the classic Unix shape of a single-purpose command-line reader, with installation paths through PyPI, pip from Git, Homebrew, Chocolatey, AUR, or manual placement in PATH. ### 采用历史 epr became popular enough for packaging across several ecosystems and accumulated notable GitHub attention for a niche terminal reader. The README also points users toward epy, the author's more featureful fork that supports more formats and reading features. ### 使用方式 Users invoke epr with an EPUB path or without arguments to resume the last read file. It stores per-file reading state in $HOME/.config/epr/config or $HOME/.epr, and it can search reading history by passing words from a previous path. ### 为什么软件包爱好者会关心 epr is the kind of package terminal users like because it turns a GUI-heavy activity into a shell command. Its small dependency footprint and plain config/state files make it easy to package and easy to reason about. ### 时间线 - 2019: The GitHub repository is created. - 2023: The repository records a February 2023 push in the cited metadata. - 2020s: The README documents installation through PyPI, Homebrew, Chocolatey, AUR, and manual PATH placement. ### Related projects - epy is the author's more featureful fork of epr. - ebooklib and rupa/epub are listed as inspirations in the README. ### 来源 - - - ## 安全说明 narrow executable package without higher-risk signals. - **Geiger 风险:** 绿色 / 低 - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
