#!/bin/bash
# 
# Script to check include/test code for common pybind11 code style errors.
# 
# This script currently checks for
#
# 1. use of tabs instead of spaces
# 2. MSDOS-style CRLF endings
# 3. trailing spaces
# 4. missing space between keyword and parenthesis, e.g.: for(, if(, while(
# 5. Missing space between right parenthesis and brace, e.g. 'for (...){'
# 6. opening brace on its own line. It should always be on the same line as the
#    if/while/for/do statment.
# 
# Invoke as: tools/check-style.sh
