The script is designed as a reminder:

  • author file terminated by a Line Feed
  • count and files name
  • code's standard
  • required and forbidden functions
  • macro definitions
  • static variables & functions declarations
  • makefile rules

Extra tests may also be performed:

  • memory leaks detection
  • speed test comparison
  • Unit Tests

Complete unit tests are handled through external frameworks whose sources are automatically downloaded, configured and updated in background when you run the script:

Install & launch

This script requires python 3.6 or above to work.

rm -rf $HOME/.brew && brew update && export PATH=$HOME/.brew/bin:$PATH && brew update && brew install python3 && cd && git clone https://github.com/Seluj78/42PyChecker.git --recursive && cd 42PyChecker

non-interactive mode

The non-interactive mode enables you to launch a test suite without any prompt. You must specify the two options --project and --path. Here is an example of use with the project libft:

python3 ~/42PyChecker/42PyChecker.py --project=libft --path=/Users/admin/Projects/libft/ --no-gui


--project + $PROJECT

Required for non-interactive mode.
Specify the name of the project you want to test.
e.g.: python3 ./42PyChecker.py --project=libft.
Must be one of the following values: 42commandements, libft or other.

--path + $PATH

Required for non-interactive mode.
This option has no effect when used without the option --project.
Specify the absolute path of directory of your project.
e.g.: python3 ./42PyChecker.py --project=libft --path=/Users/admin/Projects/libft/.

--no-author, --no-norm, --no-makefile, --no-forbidden-functions, --no-static, --no-moulitest, --no-maintest, --no-libftest, --no-extra --no-required, --no-libft-unit-test, --no-fillit-checker, --no-bonus

Disable a specific test.


This will disable all testing suites but run the other tests.


Enables speed benchmark for libft

--show-c and --show-w

These options will display respectively the License and the Warranty.
