Which is the recommended groovy plugin for Emacs? [closed]

Question

When looking for a simple groovy mode plugin for emacs to get indenting and some form of syntax highlighting, I found 3 version on the groovy website.

This page is excellent at giving the overview and some down in the weeds details, however is a bit skimpy on why to choose one over the other.

There is Jeremy Rayner's groovy-mode.el which isn't painful

There is Russel Winder's identically named groovy-mode.el which is based on cc-mode.

There Stuart Clayman inferioir groovy mode inf-groovy.el

Currently I am drawn toward Jeremy's plugin, but I feel that being not painful is a poor reason to choose one over the others.

I'd like to know which ones are recommended or which ones are to be avoided?

Answer 1

Things changed a bit since ataylor's answer: now (March 2017) the official Groovy website links to Emacs-Groovy-Mode which combines Russel Winder's and Stuart Clayman's work.

As we may expect, the repo is available on Github.

Answer 2

I use Jeremy Ranyer's groovy-mode.el for the sole reason that it worked better with my code then Russel Winder's version, at the time I tested them.

Here's a small modification I've added to Rayner's that fixes some problems (the elvis operator, if I recall correctly):

(defconst groovy-block-mid-re
   "need something here or it blows up"
   )
