# 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...
