 This is an easy to install plug-in for almost all IntelliJ based IDEs like IDEA or PyCharm. It will turn the IDE you love into into a powerful development tool for Mathematica and Wolfram Language  code. Since the plug-in and the Community Edition of IDEA  is open-source, you can use everything completely free of charge.
