The project presents itself as both a standalone CLI and a Clojure library for detecting and fixing formatting errors in Clojure source. The changelog shows a long 0.x evolution from Leiningen-era plugin usage toward modern Clojure tooling. Version 0.10.0 added support for `clj -T` tools and Babashka use, 0.10.2 added prebuilt native binaries, 0.11.0 moved important CLI options into configuration, and 0.16.x continued tightening configuration and indentation behavior. ### Adoption history cljfmt's adoption follows Clojure's build-tool culture: the README documents standalone binaries, Homebrew installation, Clojure CLI tools, Leiningen plugin usage, library usage, Babashka tasks, and editor integrations. The batch input records packages in Homebrew and Nix. Editor integrations listed by upstream include Calva, CIDER, clojureVSCode, and vim-cljfmt, indicating that cljfmt became a formatting backend used beyond direct terminal invocation. ### How it is used Users run `cljfmt check` to detect formatting errors and `cljfmt fix` to rewrite files. Projects can configure behavior through `.cljfmt.edn`, `cljfmt.edn`, or a `:cljfmt` key in Leiningen's `project.clj`. The indentation documentation explains Clojure-specific rules for macros and forms through `:indents` and `:extra-indents`, which is the core reason cljfmt is more than a generic pretty-printer. ### Why package nerds care cljfmt matters to package nerds because it packages Clojure style policy into a repeatable CLI used in CI, editors, and build tools. The move to prebuilt native binaries also made it friendlier to Homebrew-style formulae, where startup time and dependency weight matter. For Clojure ecosystems, cljfmt is a representative example of a tool that must straddle Maven coordinates, Git-based Clojure tools, Leiningen plugins, Babashka tasks, standalone binaries, and editor integrations. ### Timeline - 2014: GitHub repository created. - 2023: 0.10.0 adds Clojure CLI tool support and partial Babashka support. - 2023: 0.10.2 adds prebuilt native binaries for the CLI. - 2023: 0.11.0 splits indentation configuration and removes old CLI configuration keys. - 2026: 0.16.0 ignores `.clj` config files by default and adds additional formatting options. - 2026: 0.16.4 adds user-configuration validation. ### Related projects - Related projects include zprint, the Clojure Style Guide, Leiningen, the official Clojure CLI tools, Babashka, Calva, CIDER, clojureVSCode, and vim-cljfmt. ### 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.
