describeSteps()

[Stephen Mallette]

I just wanted to quickly mention a minor new feature that will be available in 3.1.0.  It is an addition to the utilities plugin and is basically a function called describeSteps().  When it is called from the Gremlin Console it will scan the classpath for all non-abstract Step implementations and print them in a table to display which important base classes and marker interfaces they extend/implement.  This kind of information will be useful to those developing core API/TraversalStrategy implementations.  You can see its usage in this gist:

Hi Stephen,

I wouldn't add this just yet. I would not promote "normal users" working with Steps directly as:

1. There typing will likely change soon given the work in "Gremlin Traversal Machine and Language."

2. We don't have a DSL path yet.

3. The interface API will most likely change as well.

Finally, I don't know what use this would have as a "runtime call." If someone is developing a traversal language using the "instruction set" of Gremlin, they will most likely be in JavaDoc-land, not in describeSteps()-land. ??

Perhaps, for now, you can pull this into a feature branch.

Thanks,

Marko.

well - perhaps this was more of a post for the dev list - probably shouldn't have cross-posted it.  i'll post the rest of my reply over there in case anyone cares to follow on.

If you weren't following along on the dev mailing list - i've dropped this feature based on Marko's feedback.  Easy come - easy go....

Primary because TinkerPop DOES care about your children. The little miracles they are.

You are so blessed,

Marko.
