Code::TidyAll::SVN::Precommit(3) Subversion pre-commit hook that requires files

VERSION

version 0.32

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.
