Its README describes it as a lightweight watcher inspired by antr and entr, with workflows defined in YAML or by piping file lists on standard input. ### Project history The project is authored by Cristian Oliveira and is packaged as the `funzzy` crate with two binaries, `funzzy` and the short alias `fzz`. The Cargo manifest identifies the package as MIT licensed and points to the GitHub repository as the official source. The README frames the tool around local developer workflows, especially personal automated checks similar to GitHub Actions. Its configuration evolved from a simple `.watch.yaml` task list into richer formats that share common watch rules and nest task groups. ### Adoption history Official installation instructions cover Homebrew, Nix, Cargo, source installation, and a Linux install script. That places funzzy in the small-tool ecosystem where developers can install the same workflow runner through a language package manager or an OS package manager. ### How it is used A typical workflow starts with `funzzy init`, which creates `.watch.yaml`; running `funzzy` or `fzz` then watches the configured paths and runs matching commands. The docs also support one-off shell pipelines such as feeding changed files into `funzzy 'command {{relative_path}}'`. The configuration format supports command lists, glob-style change patterns, ignore patterns, tasks that run on initialization, target filtering, fail-fast mode, non-blocking cancellation of long-running tasks, and alternate config files via `-c` or `--config`. ### Why package nerds care funzzy is interesting as a package because it packages the Unix `entr` idea in a Rust binary with a declarative YAML workflow file. It sits between a raw file watcher and a full build system: small enough to install as a CLI, but structured enough to encode repeated local checks. ### Timeline - 2023: v1.0.0 release notes describe cancellable tasks, filters, command templates, and improved output feedback. - v1.4.0: README examples document fail-fast and non-blocking workflow usage. - v1.6.0: Documentation introduces common rules and nested groups for reducing duplicated watch patterns. ### Related projects - The README explicitly cites antr and entr as inspirations. - The README notes that yq and nrr pair well with funzzy for extracting commands or speeding JavaScript and TypeScript task execution. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - 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.
