Hi Everyone, NuVoc and the j wiki are fantastic resources but I often find myself wanting a quick reference directly in the repl. So, to scratch my own itch, I've put together a simple reference addon inspired by the ngn/k built in reference docs.
The repo is on github here: https://github.com/AshyIsMe/jreference It should be straightforward to use (works for me on macos and linux): install 'github:AshyIsMe/jreference' load 'ashyisme/jreference' H H help H0 comparisons = < > _ H1 arithmetic, logical + * - % H2 powers, uniques ^ $ ~ | H3 defs, cut, ravels . : , ; H4 tally, bases, insert, grades # ! / \ H5 left, right, head, tail [ ] { } {{ }} H6 rank, do, agenda, atop " ` @ & ? H7 alphabet, booleans, permutations, find, fold a A C. D. e E. f. F. H8 integers, index of, complex, polynomials H. i. I. j. L. L: M. NB. o. p. p.. H9 primes, symbols, unicode, hook, fork p: q: r. s: S: t. T. u: x: Z: _9: 9: (u v) (f g h) u. v. H10 assert, if, for, goto, select, try catch, while The mnemonic is H for Help. H for overview, H0 for comparisons, etc I'm planning on adding some simple examples along the lines of the J Reference Card pdf, though I'm not quite sure how to format those just yet. (J RefCard: https://code.jsoftware.com/mediawiki/images/5/53/J602_RefCard_color_letter_current.pdf) I think ideally I'd prefer something like this to be built in to j but hopefully this is a simple enough prototype to see if anyone else is interested. Cheers, Aaron. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
