    picocli

    picocli

    Framework for building GraalVM-enabled command line apps

    Picocli is a one-file framework for creating Java command-line applications with almost zero code. It supports a variety of command-line syntax styles including POSIX, GNU, MS-DOS and more. It generates highly customizable usage help messages that use ANSI colors and styles to contrast important elements and reduce the cognitive load on the user. Picocli-based applications can have command line TAB completion showing available options, option parameters, and subcommands, for any level of nested subcommands. Picocli-based applications can be ahead-of-time compiled to a GraalVM native image, with extremely fast startup time and lower memory requirements, which can be distributed as a single executable file. Picocli generates beautiful documentation for your application (HTML, PDF and Unix man pages). Another distinguishing feature of picocli is how it aims to let users run picocli-based applications without requiring picocli as an external dependency.

    shadow-cljs

    shadow-cljs

    ClojureScript compilation made easy

    shadow-cljs is a ClojureScript build tool designed with simplicity and modern JavaScript interoperability in mind. Distributed via npm, it handles compilation, hot-reloading, module targets (ESM, Node, Browser), and tight integration with JS tooling. Creating your project can be done quickly using the npx create-cljs-project utility. npx is part of npm and lets us run utility scripts quickly without worrying about installing them first. The installer will create a basic project scaffold and install the latest version of shadow-cljs in the project. When building actual projects we need to configure the build first and create at least one source file.
