I've released the first complete version of my new comprehensive contest toolkit here (compatible with Linux/Mac only for now). Please check it out and send me suggestions so that I can improve the tools!
Major features include:
- Code template generator with custom templates and variables
- Program Execution/Testing module that runs code against test cases and enforces runtime limits/checks output for correctness -- works with both file (USACO-like) and stdio (ACM/Codeforces) I/O modes
- Test case management: set test data for multiple test cases (for use with the program testing module)
- Programmatic test case generation: provide a testcase generator script and effortlessly create as many test cases as you want
- Support for C, C++, Java, Python, and Shell (easily add other languages in the settings)
- Automatic memorization of language/IO mode options
- Adjustable and accessible settings file to change your coding preferences
