Some useful shortcuts for DrRacket.

Inspired by paredit

Implemented:

Movement:

• ("c:m:f") paredit-forward-sexp
• ("c:m:b") paredit-backward-sexp
• ("c:m:d") down-sexp ;rebind to "c:m:d"
• ("m:right") forward-atom ;this is not paredit shortcuts, but alternative for forward-word
• ("m:left") backward-atom ;ditto

Depth-Changing:

• ("m:s") paredit-splice-sexp
• ("m:(") paredit-wrap-round
• ("m:up") paredit-splice-sexp-killing-backward
• ("m:down") paredit-splice-sexp-killing-forward
• ("m:r") paredit-raise-sexp
• ("m:?") paredit-convolute-sexp

Slurpage & barfage

• ("c:right" "c:)" "c:]") paredit-slurp-forward
• ("c:m:left" "c:(" "c:[") paredit-slurp-backward
• ("c:left" "c:}") paredit-barf-forward
• ("c:m:right" "c:{") paredit-barf-backward

Note:

All the key bindings involving meta key "m:" can also be accessed using the Escape key, by pressing and releasing it before proceeding with the remaining keys, just like in Emacs. This is equivalent to replacing "m:" with prepended "esc;".

Moreover, "m:" can be accessed through "?:a:"(the Option Key) on MacOS.

You can see the up-to-date list of all the key bindings applied on your platform, by selecting from DrRacket's menu Edit, Keybindings, Show Active Keybindings, and filtering the list with "paredit."

Install:

  raco pkg install drracket-paredit

or manually:

1. Download the "paredit.rkt"
2. Open the 'Edit|Keybindings|Add user-defined-keybindings' dialog, select "paredit.rkt".
