Question: You have all these complicated configuration options in your package, but which ones do you as the maintainer actually set in your own configuration?
Answer: Not many, beyond custom key bindings. I set most defaults the way that seems best. However, the default settings do not turn on features which:
To see what I mean, here is the entire configuration the old maintainer had in his .emacs:
(setq idlwave-shell-debug-modifiers '(control shift) idlwave-store-inquired-class t idlwave-shell-automatic-start t idlwave-main-block-indent 2 idlwave-init-rinfo-when-idle-after 2 idlwave-help-dir "~/lib/emacs/idlwave" idlwave-special-lib-alist '(("/idl-astro/" . "AstroLib") ("/jhuapl/" . "JHUAPL-Lib") ("/dominik/lib/idl/" . "MyLib")))
However, if you are an Emacs power-user and want IDLWAVE to work completely differently, you can change almost every aspect of it. Here is an example of a much more extensive configuration of IDLWAVE. The user is King!
