# Script to check include/test code for common pybind11 code style errors.

# This script currently checks for
#
# 1. missing space between keyword and parenthesis, e.g.: for(, if(, while(
# 2. Missing space between right parenthesis and brace, e.g. 'for (...){'
# 3. opening brace on its own line. It should always be on the same line as the
# if/while/for/do statement.
#
# Invoke as: tools/check-style.sh <filenames>
