README.md

We, the module installer developers, hereby decree...

Too official? Ok, I'll go again.

In this repository you'll find metadata for projects and modules. It's nice to have that in a central place, apart from any specific module installer (cough proto neutro pls cough), for at least these three reasons:

  • The set of people who want access to a module installer and the set of people who want access to module metadata are two different sets.

  • If each installer has one set of metadata, that's more for everyone to keep updated. If it's in a central place, there's less work.

  • The list of projects in the ecosystem is really an orthogonal to the installer, or even an installer. It might be used for other things, such as rendering the list at http://modules.perl6.org

To add a new module to the ecosystem, add the URL of the module's raw META.info file to the META.list file here in the ecosystem. Since the updates to the ecosystem are announced in the #perl6 IRC channel, it is helpful if you include the HTTP URL to your repo in your commit message so others could easily view your new module, e.g.:

git commit -m 'Add FooBar to ecosystem' -m 'See https://github.com/foobar/FooBar'

So there you go. It probably bears repeating that all of this is quite temporary; something to sustain us until we can hook up with CPAN goodness in some more long-term way.

Have a nice day.

Common Errors

Some of these issues commonly occur. Be sure to check your distro:

META File

  • Check that your META file contains valid JSON. To do so, you can use an online service, such as JSON Lint.
  • Ensure you have a provides section that lists all the modules in your distribution, with correct filenames, otherwise your module will not be installable.

There is a module Test::META that can help you detect some, but not all, of the common problems people have with the META files.

Generated File

After the META.list file is processed, the list of modules is available at http://ecosystem-api.p6c.org/projects.json and any errors encountered during processing at http://ecosystem-api.p6c.org/errors.json. If your module is missing after about an hour since its addition, there may be issues with your META6.json file.

Module Take Over

It's a fact of life that some modules end up being abandoned, either due to authors losing interest, moving on to other hobbies, or even dying. In such cases, it's possible you may be interested in taking over the module, by replacing the version in the ecosystem with your own repo. To avoid accidental take overs of modules that aren't abandoned, we try to follow this process before taking over:

  • First, ensure what you're planning to do (e.g. copying the code and modifying it) is permitted by the module's license. Note that lack of a license does not mean you're free to take and modify the project and many jurisdictions give the authors of a work automatic implicit copyright.
  • If possible, contact the author by email, CCing perl6-users@perl.org, asking them if they'd be willing to give you a commit bit to the repository or let you take over the module entirely. The email address is usually visible on user's GitHub profile.
  • Try to contact the user by other means, as their GitHub notifications/emails may be disabled. Perhaps, there's a Twitter account with similar username.
  • If attempts to contact the author fail, after 4-weeks the module can be taken over.

In short, try to contact the user by more ways than simply opening a PR in their repo and give them enough time to have a chance to respond.

LEGAL

The operation of the ecosystem requires that we copy, distribute, and possibly modify your META file (META6.json or legacy META.info) in full or in part, or that we display information from that file on various websites and other systems. We can't always guarantee proper attribution, that copies are accurate, or that modifications do not inadvertently produce unintended results.

By submitting your module to the ecosystem, you agree that all entities involved in the operation of the ecosystem, including its testing, mirroring, or archiving, as well as any package installers and auxiliary tools, are allowed to copy, distribute, and modify your META file without limitation for the purposes of making your module available to the Perl 6 community—regardless of what license you choose for the rest of your distribution. You also agree not to hold these entities liable for any damage or inconvenience caused by the operation of the ecosystem or the failure to do so.
