In best billc style... ;^)
I have mentioned some of my Emacs hacks for editing Common Lisp code here, here, and here (the latter of which Troels Henriksen ported to Climacs). So, I finally dusted off some more code-wrangling Emacs macros and bundled them up in the Redshank minor mode. Obligatory screencast:

The provided functionality is quite embryonic still, but I expect it to continue to grow.

For actual code motion and manipulation of Lisp code, I heavily rely on the excellent Paredit mode, with a minimal dependency on SLIME (the dependency might grow in the future, as more sophisticated refactoring likely requires cooperation from a running Lisp.)

For laughs comparison, I'd like to see the same done for unparenthesized code...
Okay, enough smugness for today. Now read the best Common Lisp Tutorial, and start hacking away!

First Reactions after Prerelease to the Raving Masses a Priviledged Audience

antifuchs | michaelw: o_O this is awesome

     jmbr | michaelw: I've just downloaded redshank. It's quite cool!

 michaelw | pkhuong: eh, okay ECONTEXT :) defclass-skeleton now
            inserts parenthesis balanced
  pkhuong | michaelw: ah good, good! I might have to try it out then
 michaelw | (bonus: customizable accessor style)
  pkhuong | so I can have foo-of instead of get-foo too? That
          | was my other objection (:

     Xach | I am eagerly awaiting the Planet Lisp link!

p.s.: In the right window of the screencast, key strokes were recorded with mwe-log-commands.

p.p.s: The screencasting itself was a major pain. In this case, I am willing to put part of the blame on my inexperience, for the rest I blame the tools I used. A somewhat more detailed account of this may appear under the Rants section.
