Its README describes a shell-agnostic tool whose direct dependencies are curl and git, excluding the system packages needed to compile Erlang/OTP itself. kerl's design centers on separating builds from installations: once a particular OTP release is built, the build can be installed quickly into one or more destinations and activated per shell session. ### 采用历史 kerl became a durable part of Erlang and Elixir development because it solved the practical problem of compiling many OTP versions with different configure options. The asdf-erlang plugin explicitly says it relies on kerl for builds and combines kerl's compatibility/build scripts with asdf's version-switching UX. On 2026-07-01, GitHub API metadata reported 1,660 stars and 236 forks, and Homebrew metadata listed kerl 4.4.0. ### 使用方式 Users run kerl list releases, kerl build, kerl install, and shell activation scripts to work with specific Erlang/OTP versions. The README also documents building from the official Erlang/OTP GitHub tags, official Erlang downloads, or arbitrary Git refs and forks. In package-manager workflows, kerl is often the lower-level build engine beneath friendlier version managers, especially when macOS, Linux distro, OpenSSL, wxWidgets, or documentation-build quirks matter. ### 为什么软件包爱好者会关心 kerl is significant because it is small shell code that encodes years of Erlang/OTP build knowledge. It sits between language-runtime packaging and developer version management, much like ruby-build or pyenv installers do for their ecosystems. ### 时间线 - 2011-07-05: kerl/kerl repository created on GitHub. - 2023-10-12: 4.0.0 release published. - 2025-06-19: 4.4.0 release published. - 2026-07-01: Homebrew formula metadata listed kerl 4.4.0. ### Related projects - Erlang/OTP is the runtime kerl builds and installs. - asdf-erlang relies on kerl for Erlang builds while adding asdf's .tool-versions workflow. - Homebrew packages kerl directly for macOS users. ### 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.
