Subject [jira] [Commented] (EDGENT-179) console: oplet coloring gradients "too close"
Date Tue, 20 Sep 2016 17:58:20 GMT

    [ https://issues.apache.org/jira/browse/EDGENT-179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15507280#comment-15507280

Queenie Ma commented on EDGENT-179:
-----------------------------------

Currently, the oplet colors are hard-coded by oplet kind ({{invocation.kind}}) in {{graph.js}}.
The issue wih the "ParallelBalancedRecipe" sample is that the Peek oplet's kind ({{org.apache.edgent.oplet.functional.Peek}})
was not defined in {{graph.js}}, so its color was generated randomly and was chosen to be
the same color as the Union oplet. To fix this bug, we need to assign a new color to this
Peek oplet.

However, I suspect that other oplet kinds may have been missed when hard-coding these colors.
Is there a way to get a list of all possible kinds without manually looking at each of the
classes?

In the future, if an oplet kind has not been assigned a color (e.g., because it was missed
or because it is new), I think it would be a good idea to perhaps hard-code a set of unused
colors and pick one of them to assign to the oplet kind. This way, there will be no overlap.

> The oplet color generator ends up yielding two light purple-ish colors for two different
kinds of (adjacent) oplets and one can't tell them apart.  One is a Sink the other is a subtype
of Peek - a StreamScope.
> I was seeing this in a ParallelBalancedRecipe app of mine.  I can provide it if really
necessary to repro/improve this.
