Hey, Awhiles back, in the programming mailing list in one thread, there were a few comments one user made about still having the two J604 pages [0] printed out on his desk. They are a great tool for somebody unfamiliar with the language the get a feel of what does what, or just as a quick reminder, but they also lack details, in my opinion. The dictionary [1] is great, as is NuVoc [2], however all of the old J site's pages are clumsily styled, e.g., on a 1920x1080 screen, there is little reason to not fit all entries within one screen, same with nuvoc, to be honest, I have local pages with for my use better css; other example would be Learning J's whole content with within a table with the first column empty, rather than using a margin.
That said, I wanted to make a refsheet for myself, then I remember the above and thought it might be worth something to ask others' opinion on making a new refsheet in the formats: pdf, html, plain text, plain text + ANSI escape codes for color, and markdown. Attached is my WIP, wherein I've yet to figure out how to get the footnotes containing valueable-not-to-forget information to show up, I can send the source files, if somebody wishes to work with or contribute. My use of J is oriented towards maximizing tacitness, so I thought it useful to have equivalencies of more complicated primitives (albeit badly implemented since I'm a novice at best). But, then again, the originals examples are valuable, and, then again again, dictionaries show the meaning of words through definitions usings words elsewhere in the dictionary defined combined with usage examples. Though some verbs like plus are a most basic instruction for probably all CPUs, so I wouldn't initially know how to 'define' it through other opperations other than bitshifts of binary representations of the numbers or something. The ordering of the tables will be the lastmost step. That said, I'll appreciate any critique, suggestions, recommendations, comments, you might have.
