Adding cask for weka.

[leoromanovsky]

Weka is a popular tool for machine learning used by researchers. This cask starts at version 3.6.10.

Seeing as url doesn’t seem to point to a specific version, this cask should use version 'latest' and no_checksum. See an example.

[leoromanovsky]

@vitorgalvao From the documentation on URL suggestions, I thought that "latest" was the preferred URL to use. My personal preference would be to explicitly call out a certain version. What do you think of changing it to that?

[vitorgalvao]

The value of having it one way or another is an open discussion. In the meantime, however, consistency is more important than the preferences of any individual user. If you feel like having versions in every cask is the right solution, please give us your reasoning on the the linked issue.

If we change that policy, than we’ll do it for every cask, but for now, for this to be accepted, please follow the guidelines.

@vitorgalvao ok thanks, got it. I've changed it to the latest version with no checksums.

If you notice, for this particular project, the maintainers have given their app a poor name and added the version number to the file package 👎

[vitorgalvao]

I see. Maybe in that case you’d prefer to use the other kind of url (http://downloads.sourceforge.net/sourceforge/weka/weka-3-6-10-oracle-jvm.dmg). That’d allow you to set the version, like you had before, and since the app has the version in its name (which means the cask will break anyway, when the application is updated), it’d be a safer way to maintain the cask.

Travis CI doesn't like that this is throwing a warning.

Use the link I posted in the previous comment — http://downloads.sourceforge.net/sourceforge/weka/weka-3-6-10-oracle-jvm.dmg, it should work.

Thanks for your help. Adding more casks in the future will be straightforward for me.

[vitorgalvao]

No problem. Thank you for being so quick with the changes. Merged.
