Codeforces project generator

Instalation

npm install -g https://github.com/tao24/gcg.git

Usage instruction

Directory management

gcg init <task-name> [--overwrite] [--input-only]

Initializes directory with template .cpp file and tests (you should start copying tests to clipboard).

Flag --input-only makes it so it creates only *.in files, omitting *.out files. Make sure to create [task-name]_out.exe validator file working as specified below.

gcg cf <contest-td>

Initializes directory with template .cpp files and tests for codeforces' contest (with id equal to <contest-id>, as in URL on website).

Testing

gcg run <task-name> [-f <folder-name>] [-t <test-name>] [--no-compile]

Runs specified task on its tests (tests in folder tests which begin with <task-name> and all test in folder tests/<task-name>).

Available options:

• -f, --folder <folder-name> runs program on all tests in specified folder,
• -t, --test <test-name> runs program only on specified test (but it must be in either tests folder, in tests/<program-name> or in folder specified by -f <folder-name>),
• --no-compile turns off compiling program before testing.

If no corresponding .out or .ans files are found, then it tries to use <task-name>_out[.exe] executable to validate program. Validator should work as follows:

1. read from stdin test specification (<test-name>.in file)
2. read from stdin your programs' output
3. validate output
4. if result is ok, return with no result. If not, it should print non-empty string on standard output (it will be displayed in console during testing).

Note: Validator runs g++ -std=c++17 <task-name>.cpp -o <task-name>. Make sure you have a c++ compiler.
