About this Project

Project Goals

The goal of this project is to provide easy, common library code for using DBIx::Class with Mojolicious.

Repository Layout

This project follows CPAN conventions with some additions, explained below.

lib/

Modules are located in the lib/ directory. Most of the functionality of the project should be in a module. If the functionality should be available to users from a script, the script should call the module.

bin/

Command-line scripts go in the bin/ directory. Most of the real functionality of these should be in a library, but these scripts must call the library function and document the command-line interface.

t/

All the tests are located in the t/ directory. See "Getting Started" below for how to build the project and run its tests.

xt/

Any extra tests that are not to be bundled with the CPAN module and run by consumers is located here. These tests are run at release time and may test things that are expensive or esoteric.

share/

Any files that are not runnable code but must still be available to the code are stored in share/. This includes default config files, default content, informational files, read-only databases, and other such. This project uses File::Share to locate these files at run-time.

What to Contribute

Comments

The issue tracker is used for both bug reports and to-do list. Anything on the issue tracker, open or closed, is available for discussion.

Fixes

For fixes, simply fork and send a pull request. Fixes to anything, documentation, code, tests, are equally welcome, appreciated, and addressed!

If you are fixing a bug in the code, please add a regression test to ensure it stays fixed in the future.

Features

All contributions are welcome if they fit the scope of this project. If you're not sure if your feature fits, open an issue and ask. If it doesn't fit, we will try to find a way to enable you to add your feature in a related project (if it means changes in this project).

When contributing a feature, please add some basic functionality tests to ensure the feature is working properly. These tests do not need to be comprehensive or paranoid, but must at least demonstrate that the feature is working as documented.

Getting Started Building and Running Tests

This project uses Dist::Zilla for its releases, but you aren't required to use it for contributing.

These instructions do require you have App::cpanminus (cpanm) installed. cpanm is a CPAN client to install Perl modules and programs. You can install cpanm by doing:

curl -L https://cpanmin.us | perl - App::cpanminus

Or, if you (not incorrectly) do not trust that, by using the existing cpan client that comes with Perl:

cpan App::cpanminus

You may need to be root or Administrator to install cpanminus.

Using cpanm to install prereqs

The cpanm command is the easiest way to install this project's dependencies. In the root of the project, just run cpanm --installdeps . and the dependencies will be installed.

Using carton to install prereqs in an isolated directory

If you with to isolate the prerequisites of this project so they do not interfere with other projects, you can use the Carton tool. Install Carton normally from CPAN using cpanm Carton, then use the carton command to install this module's prereqs in the local/ directory:

carton install

Once the prereqs are installed, you can use carton exec prove -lr t to run all the tests with the right prereqs. Putting carton exec in front of the command makes sure Perl uses the right library directories.

Using prove to run tests

Perl comes with a utility called prove which runs tests and gives a report on failures. To run the test suite with prove, do:

prove -lr t

This will run all the tests in the t directory, recursively, while adding the current lib/ directory to the library path.

You can run individual test files more quickly by passing them as arguments to prove:

prove -l t/my-test.t

Using Dist::Zilla to install prereqs and run tests

Once you have installed Dist::Zilla via cpanm Dist::Zilla, you can get this distributions's dependencies by doing:

dzil listdeps --author --missing | cpanm

Once all that is done, testing is as easy as:

dzil test

Before you Submit Your Contribution

Copyright and License

All contributions are copyright their respective owners, so make sure you agree with the project license (found in the LICENSE file) before contributing.

The list of Contributors is calculated automatically from the Git commit log. If you do not wish to be listed as a contributor, or if you wish to be listed as a contributor with a different e-mail address, tell me so in the ticket or e-mail me at doug@preaction.me.

Code Formatting and Style

Please try to maintain the existing code formatting and style.

• 4-space indents
• Opening brace on the same line as the opening keyword
  • Exceptions made for lengthy conditionals
• Closing brace on the same column as the opening keyword

Documentation

Documentation is incredibly important, and contributions will not be accepted until documentated.

• Methods must be documented inline, above the code of the method
• Method documentation must include name, sample usage, and description of inputs and outputs
• Attributes must be documented inline, above the attribute declaration
• Attribute documentation must include name, sample value, and description
• User-executable scripts must be documented with a short synopsis, a longer description, and all the arguments and options explained
• Tests must be documented with the purpose of the test and any useful information for understanding the test.

New Prerequisites

Though this project has a cpanfile, a Makefile.PL, and maybe even a Build.PL, these files are auto-generated and should not be edited. To add new prereqs, you must add them to the dist.ini file in the following sections:

• [Prereqs] - Runtime requirements
• [Prereqs / TestRequires] - Test-only requirements
• [Prereqs / Recommends] - Runtime recommendations, for optional modules
• [Prereqs / TestRecomments] - Test-only recommendations, for optional modules

If the section doesn't already exist, you can add it to the bottom of the dist.ini file.

The Recommends and TestRecommends will be automatically installed by Travis CI to test those parts of the code.

OS-specific prerequisites can be added using the Dist::Zilla::Plugin::OSPrereqs module.
