clj-spdx

A Clojure wrapper around Spdx-Java-Library, plus some bespoke functionality (e.g. custom SPDX expression parsing).

Note that that library's functionality is being wrapped on-demand by the author based on their needs in other projects, so this wrapper library is not yet comprehensive. Contributions of any kind are warmly welcomed, especially wrapping additional parts of the Java library!

Note also that this project has no official relationship with the SPDX project (who maintain Spdx-Java-Library), and this work is in no way associated with, or endorsed by, them.

Installation

clj-spdx is available as a Maven artifact from Clojars.

Trying it Out

Clojure CLI

$ clj -Sdeps '{:deps {com.github.pmonks/clj-spdx {:mvn/version "RELEASE"}}}'

Leiningen

$ lein try com.github.pmonks/clj-spdx

deps-try

$ deps-try com.github.pmonks/clj-spdx

; This is optional but can be time consuming, so we run it explicitly to force

Code of Conduct

Developer Workflow

This project uses the git-flow branching strategy, and the permanent branches are called release and dev. Any changes to the release branch are considered a release and auto-deployed (JARs to Clojars, API docs to GitHub Pages, etc.).

For this reason, all development must occur either in branch dev, or (preferably) in temporary branches off of dev. All PRs from forked repos must also be submitted against dev; the release branch is only updated from dev via PRs created by the core development team. All other changes submitted to release will be rejected.

Build Tasks

clj-spdx uses tools.build. You can get a list of available tasks by running:

clojure -A:deps -T:build help/doc

Of particular interest are:

• clojure -T:build test - run the unit tests
• clojure -T:build lint - run the linters (clj-kondo and eastwood)
• clojure -T:build ci - run the full CI suite (check for outdated dependencies, run the unit tests, run the linters)
• clojure -T:build install - build the JAR and install it locally (e.g. so you can test it with downstream code)

Please note that the release and deploy tasks are restricted to the core development team (and will not function if you run them yourself).
