Challenger

VSCode Extension to help run and test command line programs for competitive programming competitions.

Using the extension

Open the extension webview in the VScode sidebar. You must select a language and the source code file. Optionally, you can select an input file and an output test. The input file will be passed to the standard input (stdin) of your program. The standard output will be compared to the output test file if one is selected. The input file must be in a directory called input and the output test must be in a directory called output. When looking for source code files, the extension will look through all files in the workspace's directory as well as subdirectories not named input or output. When looking for input and output files, the extension will look in any folder called input and output respectively but will not look into their subdirectories.

Example directory layout

.
├── input
│   └── input.txt
├── output
│   └── output.txt
└── sourcecode.cpp

Features

• Compile and run your code for you
• Clean up binary files after running them
• Select file to pass into the standard input of the program
• Compare standard output to a file

Important notes/FAQ

• This project is still in beta, there may be some bugs left to be ironed out.
  • Please submit bugs using the Github issues of this repo.
  • Although this extension is meant to help speed up your workflow, be sure to still know how to compile and run your code during competitions in case of a bug
  • Sometimes reloading the VScode window can solve some issues.
    • You can reload the window by searching for Developer: Reload Window in the Command Palette.
    • Alternatively, you can reload the window using the following keyboard shortcuts Command+R or Control+R on macOS and Linux/Windows respectively.
• Please make sure this tool is permitted before using it in competitive competitions. Although I suspect you will most likely be fine, use at your own risk.
• Currently, this extension only works on POSIX (macOS and Linux) systems. It does NOT work on Windows since POSIX shell commands do not work in Powershell.
  • This extension might work thorugh Windows Subsystem for Linux (WSL) although your mileage may vary.
• Make sure that you have the compiler or interpreter of the language you choose. This extension does not come with or install any compilers/interpreters. Please see the languages section for more information.
• Have fun and enjoy!

Language Support

Below are the list of languages supported by this extension and the expected compilers/interpreters as well as the command used to run them.

C

Notes: cc should be a symlink or a copy of the default system C compiler. The default C compiler on macOS should be clang and the default C compiler on Linux should be the GNU C compiler (gcc).

cc source.c -o challenger_tmpfilename.tmp
./challenger_tmpfilename.tmp

C++

Notes: c++ should be a symlink or copy of the default system C++ compiler. The default C++ compiler on macOS should be clang++ and the default C++ compiler on Linux should be g++. The C++ standard used is C++17.

c++ source.cpp -std=c++17 -o challenger_tmpfilename.tmp
./challenger_tmpfilename.tmp

Python

Notes: Python 3 is being using since support for Python 2 is deprecated.

python3 source.py

Swift

swiftc source.swift -o challenger_tmpfilename.tmp
./challenger_tmpfilename.tmp
