Code::TidyAll::Git::Precommit - Git pre-commit hook that requires files to be
This module implements a Git pre-commit hook
<http://git-scm.com/book/en/Customizing-Git-Git-Hooks> that checks if
all files are tidied and valid according to tidyall, and rejects the commit if
not. Files/commits are never modified by this hook.
See also Code::TidyAll::Git::Prereceive, which validates pushes to a shared
This class provides one method:
Checks that all files being added or modified in this commit are tidied and
valid according to tidyall. If not, then the entire commit is rejected and the
reason(s) are output to the client. e.g.
% git commit -m "fixups" CHI.pm CHI/Driver.pm
2 files did not pass tidyall check
lib/CHI.pm: *** 'PerlTidy': needs tidying
lib/CHI/Driver.pm: *** 'PerlCritic': Code before strictures are enabled
at /tmp/Code-TidyAll-0e6K/Driver.pm line 2
In an emergency the hook can be bypassed by passing --no-verify to commit:
% git commit --no-verify ...
or you can just move ".git/hooks/pre-commit" out of the way
The configuration file ("tidyall.ini" or ".tidyallrc") must
be checked into git in the repo root directory i.e. next to the .git
By default, the hook will stash any changes not in the index beforehand, and
restore them afterwards, via
git stash save --keep-index --include-untracked
git stash pop
This means that if the configuration file has uncommitted changes that are not
in the index, they will not affect the tidyall run.
This class passes mode = "commit" by default to tidyall; see modes.
A conf file name to search for instead of the defaults.
Path to git to use in commands, e.g. '/usr/bin/git' or '/usr/local/bin/git'.
By default, it just uses 'git', which will search the user's
Don't attempt to stash changes not in the index. This means the hook will
process files that are not going to be committed.
Subclass to use instead of Code::TidyAll.
A hashref of options to pass to the Code::TidyAll constructor.
This hook must be placed manually in each copy of the repo - there is no way to
automatically distribute or enforce it. However, you can make things easier on
yourself or your developers as follows:
- Create a directory called "git/hooks" at the top
of your repo (note no dot prefix).
mkdir -p git/hooks
- Commit your pre-commit script in
- Add a setup script in "git/setup.sh" containing
chmod +x git/hooks/pre-commit
ln -s ../../git/hooks/pre-commit
- Run "git/setup.sh" (or tell your developers to
run it) once for each new clone of the repo
See this Stack Overflow question for more information on pre-commit hooks and
the impossibility of enforcing their use.
See also Code::TidyAll::Git::Prereceive, which enforces tidyall on pushes to a
remote shared repository.
