linter's Introduction

linter

This repo contains a (C++, python (experimental)) linter and auto formatter package that can be included into your repository as a submodule. It provides the following git hooks:

General
- Prevent commits to master.
C++ files:
- clang-format Formats your code based on your .clang-format preferences.
- cpplint Checks your C++ code for style errors and warnings.
EXPERIMENTAL - Python files:

WARNING: The default linter settings are very strict and might not actually conform with the formatting produced by autopep8. If you want to use this linter for python you will need to do some tweaking.
- autopep8 Formats your python code.
- pylint Checks your Python code for style errors and warnings.

Dependencies

autopep8 (Introduction to autopep8)

Installation

cd $YOUR_REPO
git submodule add -b slightech https://github.com/slightech/linter.git
./linter/init-git-hooks.py

You can also add the linter submodule in a subfolder of your repo, e.g.:

mkdir $YOUR_REPO/tools
git submodule add -b slightech https://github.com/slightech/linter.git tools/linter
./tools/linter/init-git-hooks.py

Define the project-specific C++ format by adding a file .clang-format to your projects root folder. Example:
