Does an (experimental) class browser exist for Ruby?

Question

Does an (experimental) class browser exist for Ruby?

I am talking about a class browser/editor combination similar to that of most Smalltalk implementations (i.e. focused on [runtime] classes/objects instead of .rb files)

P.S.: it looks like pry is already able to do a lot of the things that would be needed by a smalltalk style class browser? https://speakerdeck.com/u/rahult/p/pry-an-irb-alternative-on-steroids

P.S.2: Looks like the Seaside Smalltalk framework has a web browser based class browser

P.S.3: MagLev/Webtools is the closest I have found yet:

P.S.4: Apparently http://tibleiz.net/code-browser/index.html has Ruby support and is able to present a Smalltalk like class browser:

Answer 1

Check out the maglev/webtools project on github, as well as the rubymirrors gem. It already provides a class browser and workspace for multiple Ruby implementations, and a graphical debugger works on MagLev as well (not so much on MRI).

Answer 2

If you want to build one, the easiest would be to use MOOSE and build the browser with Glamour, on top of a Ruby parser written in PetitParser. Then you could use Pharo as your Ruby IDE.

Answer 3

You can have a look at the Maglev Database Explorer [1, 2] as well.

Answer 4

There is. It is called Reflexive. https://github.com/dolzenko/reflexive

(I've never taken the time to try it though, so I am curious about other experiences with it.)
