NAME

Git::Lint - lint git commits and messages

SYNOPSIS

use Git::Lint;

my $lint = Git::Lint->new();
$lint->run({ check => 'commit', profile => 'default' });
$lint->run({ check => 'message', file => 'file_path', profile => 'default' });

git-lint [--check commit] [--check message <message_file>]
         [--profile <name>]
         [--version] [--help]

DESCRIPTION

Git::Lint is a pluggable framework for linting git commits and messages.

For the commandline interface to Git::Lint, see the documentation for git-lint.

For adding check modules, see the documentation for Git::Lint::Check::Commit and Git::Lint::Check::Message.

CONSTRUCTOR

new

Returns a reference to a new Git::Lint object.

METHODS

run

Loads the check modules as defined by profile.

run expects the following arguments:

profile

The name of a defined set of check modules to run.

check

Either commit or message.

file

If check is message, file is required.

config

Returns the Git::Lint::Config object created by Git::Lint.

INSTALLATION

To install Git::Lint, download the latest release, then extract.

tar xzvf Git-Lint-0.008.tar.gz
cd Git-Lint-0.008

or clone the repo.

git clone https://github.com/renderorange/Git-Lint.git
cd Git-Lint

Generate the build and installation tooling.

perl Makefile.PL

Then build, test, and install.

make
make test && make install

Git::Lint can also be installed using cpanm.

cpanm Git::Lint

CONFIGURATION

Configuration is done through git config files (~/.gitconfig or /repo/.git/config).

Only one profile, default, is defined internally. default contains all check modules by default.

The default profile can be overridden through git config files (~/.gitconfig or /repo/.git/config).

To set the default profile to only run the Whitespace commit check:

[lint "profiles.commit"]
    default = Whitespace

Or set the default profile to Whitespace and the fictional commit check, Flipdoozler:

[lint "profiles.commit"]
    default = Whitespace, Flipdoozler

Additional profiles can be added with a new name and list of checks to run.

[lint "profiles.commit"]
    default = Whitespace, Flipdoozler
    hardcore = Other, Module, Names

Message check profiles can also be defined.

[lint "profiles.message"]
    # override the default profile to only contain SummaryLength, SummaryEndingPeriod, and BlankLineAfterSummary
    default = SummaryLength, SummaryEndingPeriod, BlankLineAfterSummary
    # create a summary profile with specific modules
    summary = SummaryEndingPeriod, SummaryLength

An example configuration is provided in the examples directory of this project.

ENABLING CHECKS FOR REPOS

To enable as a pre-commit hook, copy the pre-commit script from the example/hooks directory into the .git/hooks directory of the repo you want to check.

Once copied, update the path and options to match your path and preferred profile.

To enable as a commit-msg hook, copy the commit-msg script from the example/hooks directory into the .git/hooks directory of the repo you want to check.

KNOWN CAVEATS

Since the default commit check profile runs all commit checks by default, an unchanged default profile will not allow the user to add a commit since they'll get a warning for either indent tabs or indent spaces. To work around this, create a new profile, or override the de fault profile, to use the one being used for the project.

[lint "profiles.commit"]
    default = Whitespace, IndentSpaces

Both the IndentTabs and IndentSpaces commit checks overlap with the MixedIndentTabsSpaces check. A user may find two warnings given if mixed indent tabs and spaces are found; one for the tab (or space) indent and one for the mixed indent tab (or space).
