NAME

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

VERSION

       version 0.18

SYNOPSIS

         In hooks/pre-commit in your svn repo:

           #!/usr/bin/perl
           use Code::TidyAll::SVN::Precommit;
           use Log::Any::Adapter (File => "/path/to/hooks/logs/tidyall.log");
           use strict;
           use warnings;

           Code::TidyAll::SVN::Precommit->check();

DESCRIPTION

       This module implements a Subversion pre-commit hook <http://svnbook.red-
       bean.com/en/1.7/svn.ref.reposhooks.pre-commit.html> that checks if all files are tidied
       and valid according to tidyall, and rejects the commit if not.

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.

               % svn commit -m "fixups" CHI.pm CHI/Driver.pm
               Sending        CHI/Driver.pm
               Sending        CHI.pm
               Transmitting file data ..svn: Commit failed (details follow):
               svn: Commit blocked by pre-commit hook (exit code 255) with output:
               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 prefixing the comment with "NO TIDYALL",
           e.g.

               % svn commit -m "NO TIDYALL - this is an emergency!" CHI.pm CHI/Driver.pm
               Sending        CHI/Driver.pm
               Sending        CHI.pm
               Transmitting file data .
               Committed revision 7562.

           The configuration file ("tidyall.ini" or ".tidyallrc") must be checked into svn. For
           each file, the hook will look upwards from the file's repo location and use the first
           configuration file it finds.

           By default, if the configuration file cannot be found, or if a runtime error occurs, a
           warning is logged (see "LOGGING" below) but the commit is allowed to proceed. This is
           so that unexpected problems do not prevent valid commits.

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

           Key/value parameters:

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

           emergency_comment_prefix
               Commit prefix that will cause this hook to be bypassed. Defaults to "NO TIDYALL".
               e.g.

                   svn commit -m "NO TIDYALL - must get fix to production!"

               Set to a false value (e.g. blank or undefined) to disable bypassing.

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

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

               If you don't list them here then you'll get errors like 'cannot find perlcriticrc'
               when the hook runs.

           reject_on_error
               If the configuration file cannot be found for some/all the files, or if a runtime
               error occurs, reject the commit.

           repos
               Repository path being committed; defaults to $ARGV[0]

           tidyall_class
               Subclass to use instead of Code::TidyAll

           tidyall_options
               Hashref of options to pass to the Code::TidyAll constructor

           txn Commit transaction; defaults to $ARGV[1]

LOGGING

       This module uses Log::Any to log its activity, including all files that were checked, an
       inability to find the configuration file, and any runtime errors that occur. You can
       create a simple date-stamped log file with

           use Log::Any::Adapter (File => "/path/to/hooks/logs/tidyall.log");

       or do something fancier with one of the other Log::Any adapters.

       Having a log file is especially useful with pre-commit hooks since there is no way for the
       hook to send back output on a successful commit.
