Various customizations for DrRacket to make life easier.

• Though it may not be necessary in all cases, DrRacket should be restarted after most customizations to allow all changes to take effect.

Acknowledgements

Racket Preferences

Features

• Dark mode based on Monokai v2.1
• [ (left square bracket) will automatically determine the right bracket for you (no need to Shift+9 anymore!) and insert a close bracket for you as well
• In addition to the notable ones mentioned here, I enabled all the features I find useful. The language is set to Beginning Student Custom, the starting language for CS 135 at UWaterloo. This may change as I progress through the course, or it may not.

Installation

• Unix: Put racket-prefs.rktd in $HOME/.racket and reload DrRacket
• Windows: Put racket-prefs.rktd in %appdata%\\Racket (paste that into the File Explorer location bar and hit enter) and reload DrRacket
• Mac OS: Rename racket-prefs.rktd to org.racket-lang.prefs.rktd and put it in your preferences folder and reload DrRacket

Autocomplete

Features:

• Completion for the following:

Shortcut	Long form
cx	check-expect
cw	check-within
ce	check-error
df	define function
d	define
t	true
f	false
hdr	file header
cmt	comment
l;	;;
ppe	Purpose and examples
ctr	Contract
req	Requires
tst	Tests
lox	List-of-X Template

• Ctrl+Space trigger

Installation

This will be automated when I get around to the raco package.

You can optionally install the drcomplete raco package for automated code-completion (i.e. you won't have to Ctrl+/ all the time.) To do this, go to File > Package Manager..., make sure you're on the Do What I Mean tab, put drcomplete in the input field beside Package Source:, and click Install at the bottom right of the window. Restart DrRacket, then go to Edit > Enable Automatic Autocompletion (last item) in the menubar (if it's not already enabled).

1. Go to Scripts > Manage scripts > New script... from the menubar
2. Enter autocomplete as the name and click Ok
3. Wait for a new tab to be created, and paste in everything in autocomplete.rkt
4. Restart DrRacket or Scripts > Manage scripts > Compile scripts and reload and Scripts > Manage scripts > Reload menu

Usage:

1. Type a shortcut
2. Press Ctrl+Space
3. The shortcut will be replace with the long form

Keybindings

Features

• Current custom keybindings that I'm used to and have implemented are:

Keybinding	What it does	DrRacket default
Alt+R	Run the program	Ctrl+R or F5
Ctrl+Shift+F	Indent all lines	Ctrl+I
Ctrl+H	Show Replace	Ctrl+Shift+R
Ctrl+Shift+R	Replace All	None
Ctrl+/	Comment out line with ;	None
Ctrl+Backspace	Delete word left of cursor	Alt+Backspace
Ctrl+Delete	Delete word right of cursor	Alt+Delete
Ctrl+Up/Down	Switch between Interactions and Definitions panes	Ctrl+F6

Installation

Go to Edit > Keybindings > Add User-Defined-Keybindings and choose keybindings.rkt. DrRacket needs to be restarted for keybindings to be updated.
