LilyGO T-Deck arithmetic symbols <>

#1

In a LilyGo T-Deck device with uLisp uploaded, how can you use the symbols: <>?

#2

Unfortunately the T-Deck keyboard is a bit limited. Unless another T-Deck user has a better idea, my suggestion is to use the Serial Monitor to define synonyms for the functions you want to access, such as <, <=, >, >= as follows:

(defvar lt <)
(defvar le <=)
(defvar gt >)
(defvar ge >=)

You can then make them available when you’re using the T-Deck away from the computer; see Preloading functions in uLisp.

You can update the keyboard firmware with whatever characters you want, but it takes some effort. I wrote how to do it in this repo. It doesn’t have those symbols, but if you find a good place for them or have other ideas let me know.
