Re: [racket-dev] Project Idea to port Paredit mode to DrRacket.
FWIW, I like the Alt-Arrows keybindings of DrRacket for moving around s-exp, but they can probably be improved. For example, Alt-Up goes up one level, and Alt-Shift-Up selects from the cursor's position to the left paren. It would probably be better if it selected the whole surrounding s-exp. If you haven't seen it yet, you can also activate Edit/Racket/Automatically adjust closing parentheses. The new behavior of the double-quotes with this is great too (and goes slightly beyond paredit, IIUC).

This is a feature that I like a lot from paredit, because it provides some level of confidence that I won't have silly mismatched parens. One improvement over paredit that I'd like to see in a DrRacket port is to handle #; comments correctly. For the features of paredit that are already in DrRacket, it'd be nice if the paredit plugin could just change the keybindings around so that those of us who are used to emacs+paredit can use it without re-training (unless this is already the case).

Re: [racket-dev] Project Idea to port Paredit mode to DrRacket.
Mayank, paredit-like features for DrRacket would be good. You might also want to look at some similar work from around the same time as paredit was created: http://cs.brown.edu/research/plt/software/divascheme/ Neil V. _ Racket Developers list: http://lists.racket-lang.org/dev

That sounds like a great project idea! I just wanted to comment that if you get this working, I would definitely use it. And I was wondering if I could work on porting it. Can anyone guide me into what is possible? What I should be looking at etc? You will probably want to look into the main text editing interfaces in Racket's GUI library such as editor%, text%, and racket:text%. http://docs.racket-lang.org/gui/editor___.html http://docs.racket-lang.org/gui/text_.html http://docs.racket-lang.org/framework/Racket.html#%28def._%28%28lib._framework%2Fmain..rkt%29._racket~3atext~3c~25~3e%29%29 (maybe you can port paredit by replacing the emacs text buffer manipulation function calls with method calls into these interfaces) Cheers, Asumu _ Racket Developers list: http://lists.racket-lang.org/dev

One of the original goals of Guile (a Scheme implementation that was once intended to be the new GNU language, including for Emacs) was to implement backward-compatibility interpreter for existing Emacs Lisp add-ons code. If someone made a Racket #lang emacs-lisp that used DrRacket text buffers -- even if only a small subset of Emacs Lisp operations -- I think that would earn them some kudos, besides being a fun exercise for Racket's language support. (The hardest part might be translating some of the Emacs Lisp dynamically-scoped variables into Racket parameters. You don't need the dynamic scoping for most of them, though, but you have to decide which ones.) Neil V. _ Racket Developers list: http://lists.racket-lang.org/dev
