man Code::TidyAll::Git::Precommit (3): Git pre-commit hook that requires files to be

VERSION

version 0.32

SYNOPSIS

In .git/hooks/pre-commit:
#!/usr/bin/env perl
use strict;
use warnings;
use Code::TidyAll::Git::Precommit;
Code::TidyAll::Git::Precommit->check();

DESCRIPTION

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 repo.

METHODS

check (key/value params...)

Class method. Check 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
      [TestingAndDebugging::RequireUseStrict]

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 temporarily.

The configuration file ("tidyall.ini" or ".tidyallrc") must be checked into git in the repo root directory i.e. next to the .git directory.

The hook will stash any changes not in the index beforehand, and restore them afterwards, via

    git stash -q --keep-index
    ....
    git stash pop -q

This means that if the configuration file has uncommitted changes that are not in the index, they will not affect the tidyall run.

Passes mode = ``commit'' by default; see modes.

Key/value parameters:

conf_name: Conf file name to search for instead of the defaults.
git_path: Path to git to use in commands, e.g. '/usr/bin/git' or '/usr/local/bin/git'. By default, just uses 'git', which will search the user's PATH.
no_stash: Don't attempt to stash changes not in the index. This means the hook will process even files that are not going to be committed.
tidyall_class: Subclass to use instead of Code::TidyAll
tidyall_options: Hashref of options to pass to the Code::TidyAll constructor

USING AND (NOT) ENFORCING THIS HOOK

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 "git/hooks/pre-commit" containing:

    #!/usr/bin/env perl
    use strict;
    use warnings;
    use Code::TidyAll::Git::Precommit;
    Code::TidyAll::Git::Precommit->check();

Add a setup script in "git/setup.sh" containing

    #!/bin/bash
    chmod +x git/hooks/pre-commit
    cd .git/hooks
    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
