NAME

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

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
