@Bubbler Ah, for integers — good point.

@Bubbler ⍳ and related functions use hash tables that are discarded when the primitive is done. If you use ¨ it cannot retain a table from call to call.

since APL has a history of being used to prove lemmas, is there some sort of APL proof checker out there?

@ZhengqunKoo Not that I know of.

@dzaima Feature request for the APL app: copying to and pasting from the app. Pain in the butt trying to use it to do Advent of Code when I can't even paste the puzzle input into the app XD

@Sherlock9 ^C and ^V above and below delete key to paste/copy text from the input box. app.cpy'string' to copy to clipboard (yes, i know that's very annoying to use, i'll do something about it at some point. normal selection doesn't work because all text stuff is custom because processing doesn't give (easy) access to native android textboxes)

(also, as a hacky way to input multiline data, f←{} ¶ )ed f and just using that as a general multiline code box that gets assigned to f upon execution)

sometime hopefully today ill release a new version with the possibility of opening the native keyboard, making app.cpy accept any data type, and inserting it on ^C with no selection

@dzaima done, though i haven't figured out perhaps the most important thing - how to read non-ASCII chars from the native keyboard :| (and i'm leaving resizing the gui around the virtual keyboard for later)
