pub.dartlang.org and Github webhooks

[Gonzalo Chumillas]

It would be nice to implement a mechanism to automatically update Dart packages from Github. Composer (a PHP package manager) already implement it:

https://packagist.org/

It pulls the packages from Github every time a new release (tag) is published. This will prevent the user to execute again and again the "pub publish" command. And also it will ensure that all packages are up-to-date.

That's my suggestion. Sorry for my basic English :)

What do you mean by automatically?

pub upgrade 

updates dependencies. I don't use git dependencies a lot. Is there any problem with it?

You can change your pubspec.yaml file to a git url directly. 

"And also it will ensure that all packages are up-to-date."

That might be dangerous, if the new package has broken changes.

What I mean is this: usually every project is stored in two repository managers. A dartlang repository manager:

https://pub.dartlang.org/

and a GitHub repository manager:

https://github.com/

If you want to upload or update your project to pub.dartlang.org, just change the version number (pubspec.yaml) and execute the following command:

> pub publish

If you want to upload/update your project to GitHub, just execute the following command:

> git push

There's something very interesting in GitHub called Webhooks. A 'webhooks' notifies to other services that the repository has changed. This way, we do not need to execute the "pub publish" command. Just "git push":

# push your project and notify pub.dartlang.org that something has changed
> git push

This is how packagist.org works. And it is great.

Yeah, we've talked about this before. It would be handy.

It's a little hairy to implement because of authentication and stuff, which is partially why it's never bubbled up to be a high enough priority for us to do.

I think it would be possible to do it outside of pub itself, though. Some enterprising individual could probably build a little system that does all of this by invoking pub lish as needed after it sees a new tag has been pushed.

Cheers!

A CI system should be able to handle this fine. I was planning on having a hookup with Drone that would publish a package if the pubspec.yaml version was updated. I did the same thing with NPM here at work. The issue with the Drone one is that these would be private packages so I've been waiting on https://github.com/dart-lang/pub/issues/1381 to really give it a go.
