NAME

       Code::TidyAll::Git::Prereceive - Git pre-receive hook that requires files to be tidyall'd

VERSION

       version 0.32

SYNOPSIS

         In .git/hooks/pre-receive:

           #!/usr/bin/perl
           use Code::TidyAll::Git::Prereceive;
           use strict;
           use warnings;

           Code::TidyAll::Git::Prereceive->check();

           # or

           my $input = do { local $/; <STDIN> };

           # Do other things with $input here

           my $hook = Code::TidyAll::Git::Prereceive->new();
           if (my $error = $hook->check_input($input)) {
               die $error;
           }

DESCRIPTION

       This module implements a Git pre-receive hook <http://git-scm.com/book/en/Customizing-Git-
       Git-Hooks> that checks if all pushed files are tidied and valid according to tidyall, and
       rejects the push if not.

       This is typically used to validate pushes from multiple developers to a shared repo,
       possibly on a remote server.

       See also Code::TidyAll::Git::Precommit, which operates locally.

METHODS

       check (key/value params...)
           An all-in-one class method. Reads commit info from standard input, then checks that
           all files being added or modified in this push are tidied and valid according to
           tidyall. If not, then the entire push is rejected and the reason(s) are output to the
           client. e.g.

               % git push
               Counting objects: 9, done.
               ...
               remote: [checked] lib/CHI/Util.pm
               remote: Code before strictures are enabled on line 13 [TestingAndDebugging::RequireUseStrict]
               remote:
               remote: 1 file did not pass tidyall check
               To ...
                ! [remote rejected] master -> master (pre-receive hook declined)

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

           In an emergency the hook can be bypassed by pushing the exact same set of commits 3
           consecutive times (configurable via "allow_repeated_push"):

               % git push
               ...
               remote: 1 file did not pass tidyall check

               % git push
               ...
               *** Identical push seen 2 times
               remote: 1 file did not pass tidyall check

               % git push
               ...
               *** Identical push seen 3 times
               *** Allowing push to proceed despite errors

           Or you can disable the hook in the repo being pushed to, e.g. by renaming
           .git/hooks/pre-receive.

           If an unexpected runtime error occurs, it is reported but by default the commit will
           be allowed through (see "reject_on_error").

           Passes mode = "commit" by default; see modes.

           Key/value parameters:

           allow_repeated_push
               Number of times a push must be repeated exactly after which it will be let through
               regardless of errors. Defaults to 3. Set to 0 or undef to disable this feature.

           conf_name
               Conf file name to search for instead of the defaults.

           extra_conf_files
               A listref of extra configuration files referred to from the main configuration
               file, e.g.

                   extra_conf_files => ['perlcriticrc', 'perltidyrc']

               These files will be pulled out of the repo alongside the main configuration file.
               If you don't list them here then you'll get errors like 'cannot find perlcriticrc'
               when the hook runs.

           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.

           reject_on_error
               Whether "check()" should reject the commit when an unexpected runtime error
               occurs. By default, the error will be reported but the commit will be allowed.

           tidyall_class
               Subclass to use instead of Code::TidyAll

           tidyall_options
               Hashref of options to pass to the Code::TidyAll constructor. You can use this to
               override the default options

                   mode  => 'commit',
                   quiet => 1,

               or pass additional options.

       new (key/value params...)
           Constructor. Takes the same parameters documented in check(), above, and returns a new
           object which you can then call "check_input" on.

       check_input (input)
           Run a check on input, the text block of lines that came from standard input.  You can
           call this manually before or after you do other processing on the input. Returns an
           error string if there was a problem, undef if no problems.

KNOWN BUGS

       This hook will ignore any files with only a single line of content (no newlines), as an
       imperfect way of filtering out symlinks.
