- * Temporary deploy command used to create a version of the app that can be

[Siggi Cherem (dart-lang), 2013/09/08 20:31:33]

Let's revert the changes to lib/deploy.dart bin/deploy.dart for now. We could
move them to a separate CL, but I'm not sure yet what is the right design here.
It might help if we first meet and brainstorm about it in person.

Long story short: So far pub's convention says to put tools under 'bin', but
these tools are not visible if you are installing this package via pub. Right
now the best I've found is to create a build.dart on each user's directory,
which internally calls this script. I think you are right that calling it 'main'
might be confusing, so maybe renaming 'main' to 'deploy' might make more sense?

This is currently on the top of my list for this week.

- * compiled with dart2js and deployed. Following pub layout conventions, this
- * script will treat any HTML file under a package 'web/' and 'test/'
- * directories as entry points.
- *
- * From an application package you can run deploy by creating a small program
- * as follows:
- *
- *    import "package:polymer/deploy.dart" as deploy;
- *    main() => deploy.main();
- *
- * This library should go away once `pub deploy` can be configured to run
- * barback transformers.
