v is definitely prettier than lr. I'd be concerned about the processing time for a large array.
A useful enhancement to J would be that 1!:2 could be set to a customized verb (that defaults to current ":). The J environment would call that custom verb (say called write_z_ instead of 1!:2) > finding a consistent way to represent the blend between literal and unicode One of the things that struck me in your first video is that your "outlined" numbers exist as unicode glyphs in mainstream fonts, and an alternative to graphics would be reglyphing some numeric types (though not touching strings) The current implementation of 1!:2/": returns utf8 (type 2= string) for things. Though this is really a huge power of jhs, and your hook/hack method is a neat way of being able to produce html output in the console that could even be a clickable interactive interface to executing more functions. html > unicode in display power. ----- Original Message ----- From: robert therriault <[email protected]> To: [email protected] Cc: Sent: Friday, July 10, 2015 12:04 PM Subject: Re: [Jgeneral] NYCJUG Tuesday, 7/14 18:30, Heartland basement, 34th Street & Fifth Avenue, NYC Thanks Pasal, The "enhanced display mode" I did by making some alterations to input_jhs_, essentially I just prepended 'visual ' to each log input and then processed it. I was not comfortable creating those side effects for users so I went with just requiring the 'v' prefix. The subtle distinction between lr and v is that lr reveals the way that the result could be created and v interprets the result visually. If you are experienced in J this might be the same thing, but I think that v gives an easier way of spotting results that you might not have expected i.e. list instead of atom, or literal instead of integer. Thanks for the feedback and I especially interested in the explorations that you have made into unicode, since finding a consistent way to represent the blend between literal and unicode is one of the things that I am currently contemplating.
