Introduction
Lightweight Rust IDE based on PyQt. (C++ and Python support is experimental)
This IDE is simplified and specialized to competitive programming, user can concentrate on programming and can achieve best performance.
When you open the contest problem page, input and output example of the problem is downloaded automatically in the background.
Then testing with sample cases, debugging with test cases, and submission can be by one click.
Feature
- Rust / C++ / Python
- GUI debug
- Online judge testcases downloading and testing. (based on online-judge-tools)
- Debug with online judge testcases

- Completer and jumper (based on racer)
- Auto Formatting (based on rustfmt)
- Rust REPL (based on evcxr_repl)
- Live Templates (IntelliJ style)
- Contest Task Browsing
- Display graph structure
