# Usage: add this file to your project's .git/hooks directory. Rename it to

# just 'pre-commit'.

# Now, when you change some files in repository and try to commit these

# changes, git will run this script right before commit. Cppcheck will scan

# changed/new files in repository. If it finds some issues, script returns with

# exit code 1, rejecting commit. Otherwise, script returns 0, and you can

# actually commit your changes.

# Example:

# $ cat hello.c

# int main() {

# int *s = malloc(10);

# }

# $ git add hello.c

# $ git commit

# Checking hello.c...

# [hello.c:3]: (error) Memory leak: s

# [hello.c:2]: (error) The allocated size 10 is not a multiple of the underlying type's size.

# $ vim hello.c

# $ cat hello.c

# int main() {

# }

# $ git add hello.c

# $ git commit

# Checking hello.c...

# $
