The project stayed centered on one portable Bash script while accumulating tool-specific version detection, readable success and failure output, meaningful exit status, and project-local `.hasrc` files. A tagged GitHub release series is visible from v1.2.0 in 2018 through v1.5.2 in August 2025. The README continues to present direct download and execution as first-class options alongside package managers. ### 采用历史 has spread through several conventions favored by shell users: direct `curl` execution, a copied script on `PATH`, Git installation, Homebrew, asdf, and mise. Supplied metadata also records Homebrew and Nix packages. ### 使用方式 Users run commands such as `has node npm java git`; the output lists detected versions, and the exit status counts missing commands. A project can commit one tool name per line in `.hasrc`, letting `has` serve as an immediately readable environment preflight for developers and scripts. ### 为什么软件包爱好者会关心 has is a strong example of the single-file shell package: no runtime beyond Bash, directly inspectable source, multiple install methods, and behavior useful both interactively and in automation. A committed `.hasrc` also acts as a lightweight executable declaration of a repository's external toolchain. ### 时间线 - 2014: The official GitHub repository is created. - 2018: v1.2.0 begins the visible GitHub release series. - 2025: v1.5.2 is released in August. ### Related projects - asdf-has packages has as an asdf plugin. - mise can install has through its version-manager workflow. ### 来源 - - - - source_facts.package-manager ## 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.
