Code::TidyAll::Git::Prereceive(3pm)

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

VERSION
version 0.85

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
This class provides the following methods:

  Code::TidyAll::Git::Prereceive->check(%params)
This 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

    An arrayref 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.

  Code::TidyAll::Git::Prereceive->new(%params)
This takes the same parameters documented as documented in "check" above and returns a new object which you can then call "check_input" on.

  $prereceive->check_input($input)
Runs 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 or undef if there were 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.
