The Integrated Development Environment for Perl 6.

BETA available through the Supporter Program from May 2018.

Built on the tried and tested JetBrains IDEA platform, which powers numerous popular IDEs on Windows, Linux, and OSX.
Uses a custom parse engine to get as close to the Perl 6 grammar as possible, providing precise syntax highlighting.
Runs applications and tests directly from the IDE, visualizing the test results with a graphical interface.
Performs realtime analysis of code, to point out common problems before the code is even run.
Works as a standalone IDE, and also as a plugin for IntelliJ, WebStorm, and other JetBrains IDEs.
