Clojure on IntelliJ: Using open-source plugins - Fücher

Arthur Fücher introduces two open-source Clojure plugins for IntelliJ that bring Clojure LSP and REPL-driven development to the IDE.

IntelliJ is a popular IDE used by many developers, and now it has open-source options for Clojure development! We’ve created two open-source plugins written in Clojure: - IntelliJ Clojure LSP, which brings the full power of Clojure LSP into IntelliJ—just like what users of VSCode and Emacs enjoy—making it easier to maintain consistent tooling across different editors. - IntelliJ Clojure REPL, which brings the REPL-driven development experience into the IntelliJ environment. In this talk, I'll share about: - features that LSP can provide to you and your projects; - how to configure, execute and interact with REPL; - create code snippets to be executed as shortcuts (and export inside your libs!); - and more.. Both projects are open-source and written in Clojure, offering the community access to the source code and the opportunity to contribute and hack your own development environment.
