    Competitive Programming Booster 🡲


    cpbooster is a cross-platform CLI tool designed to boost competitive programmer's speed during contests by automating various routine tasks like compiling and testing, debugging, cloning testcases, loading template, etc. The console command suits any coding environment (i.e. VSCode, Jetbrains IDEs, Vim, Emacs, Geany, Sublime Text, ...) and it’s very easy to use. Vim / NeoVim users can install cpbooster.vim plugin to boost their speed even more.

    Using NeoVim:


    For Installation and Setup Instructions Visit cpbooster Website


    1. cpbooster comes with a short alias command called cpb to avoid writing the long command each time

    2. Automatically clone sample testcases files with corresponding source code files with template loaded into a desired directory

      • cpb clone waits for competitive companion plugin to send parsed data for each problem
    3. Test your code against sample testcases quickly

      • cpb test mycode.cpp test your program against all available test cases
      • cpb test mycode.cpp -t 1 test your program against the test case with the given id
      • cpb test /some/path/mycode.cpp test a program that is not located in your current location

      Supported results:

      • AC (Accepted)
      • WA (Wrong Answer) Shows differences between accepted output and your output beautifully
      • TLE (Time Limit Exceeded)
      • RTE (Runtime Error)
      • CE (Compilation Error)
    4. Run code with your own debugging flags easily

      • cpb test mycode.cpp -d to use keyboard as input
      • cpb test mycode.cpp -t 2 -d to use a test case file as input
      • cpb test /some/path/mycode.cpp -d debug a program that is not located in your current location
    5. Submit your code from the terminal really quickly.

      • cpb submit mycode.cpp submits your file to the corresponding judge.
    6. open your preferred editor in the contest directory immediately after cloning it. See Editors

    7. Create source files with corresponding template loaded

      • cpb create creates single file with corresponding template loaded based on file extension
      • cpb create {a..n}.cpp creates multiple consecutive files from "a.cpp" to "n.cpp"
      • cpb create {a...n}.cpp same as previous command (Any amount of dots greater than 1 work)
      • cpb create {a-n}.cpp same as previous command (Single dash also works)
      • cpb create /some/path/a.cpp creates "a.cpp" in the specified path instead of current location
      • cpb create /some/path/{a-n}.cpp creates "a.cpp ... n.cpp" in the specified path instead of current location
    8. Vim plugin cpbooster.vim boosts your speed even more
