New attribute: topics

[uilianries]

Hi!

Bincrafters have adopted the custom attribute homepage, which describes the author's URL. But thinking about the future, this attribute could be extracted from the recipe to fill Bintray page.

Now thinking about a possible new attribute and the possibility of having it in the future (Conan 2.0). Bintray uses labels to describe multiple topics related to the project. Github there is the same feature but it uses the name topics.

It could be:

class HelloConan(conanfile):
    name = "hello"
    version = "0.1.0"
    labels = ["example", "hello-world", "first-program"]
    ...

I would like to discuss this idea to integrate our efforts on integrating Bintray, including possible new attributes for Conan.

• I've read the CONTRIBUTING guide.
• I've specified the Conan version, operating system version and any tool that can be relevant.
• I've explained the steps to reproduce the error or the motivation/use case of the question/suggestion.

Better call it tags, as in Bintray.

tags sounds good

Should I include homepage also?

We discussed a longtime ago about homepage and it could be re-used to fill Bintray.

Many of Bincrafters recipes are using homepage.

@uilianries could homepage be confusing having url already there? I dont care too much, lets vote

Could be confusing when you are creating a recipe on same project tree. But it's documented.

Also when you are creating a recipe for a remote project is totally relevant, because you could find where is the original project and that info could be used to fill both Bintray and Github pages.

This feature could also be used for #3498 isn't it?

[Aalmann]

Does it also work for Artifactory?

Does it also work for Artifactory?

This adds a new official attribute to conanfiles. In which way they are getting used is pretty much a follow up.

Ok. Thought the information will be published to Bintray as artifact property.

[uilianries]

The idea is getting Conan plugins to fill Artifactory and Bintray metadata.

I support this idea, as GitHub and Bintray need this information as well, and we may use plug-ins to fill all information automatically from the recipe
however, name tags might be very confusing, as it might refer to Git tags (or SVN tags), that's why GitHub uses topics instead of tags - exactly to avoid this confusion

[uilianries]

topics sounds great too
