NAME

       Code::TidyAll::Git::Precommit - Git pre-commit hook that requires files to be tidyall'd

VERSION

       version 0.18

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

       See also Code::TidyAll::Git::Prereceive, which enforces tidyall on pushes to a remote
       shared repository.
