Re: [Jprogramming] Arg min

In the Arabian Nights, there are many tales involving castles with locked doors. Behind each door is an unexpected world more intriguing than the last. Well, J is like that. I am standing in awe before the latest door labelled Special Codes. On Sat, 28 Dec 2019, 20:06 Ric Sherlock, wrote: > The

Re: [Jprogramming] translating scheme code

I would like to help, but I don't get what is called for.  Maybe there are Scheme users who will pipe up. If not, can you describe what the desired input and output are? Henry Rich On 12/28/2019 8:51 PM, Raoul Schorer wrote: Hi, I am trying to implement minikanren

Hi, I am trying to implement minikanren in J. I have it almost working, but I am stuck in the last part of the core implementation . I do not understand how to write "call/fresh" from the scheme cod

Re: [Jprogramming] Jhs on iPad via lan to Mac

For some reason (which I do not understand) mine wound up under /Users/jamesrussell/j901-users/config/65002.cfg. Probably due to jhs not having an "edit" command, which I had to go to Jqt to find, and the finder working overtime to protect me from myself. Is that why I have to rerun it under jc

Your 65002.cfg file would have been a trivial edit to the base JHS config file which is at: ~addons/ide/jhs/config/jhs.cfg On Sat, Dec 28, 2019 at 12:51 PM 'Jim Russell' via Programming < programm...@jsoftware.com> wrote: > I think I somehow lost my 65002.cfg file > on the upgrade to the j901 rel

I think I somehow lost my 65002.cfg file on the upgrade to the j901 release. Likely something dumb I did. > On Dec 28, 2019, at 12:30 PM, Eric Iverson wrote: > > I doubt very much that the level of JE would affect things as you describe. > But a new iOS certainly could. > >> On Sat, Dec 28, 2

Re: [Jprogramming] Jhs on iPad via lan to Mac

I doubt very much that the level of JE would affect things as you describe. But a new iOS certainly could. On Sat, Dec 28, 2019 at 12:15 PM 'Jim Russell' via Programming < programm...@jsoftware.com> wrote: > FWIW: I had iOS to jhs working over the lan for the last j beta. I _think_ > I would have

Re: [Jprogramming] Jhs on iPad via lan to Mac

FWIW: I had iOS to jhs working over the lan for the last j beta. I _think_ I would have noticed a failure to open other web pages. I lost the ability to connect after I upgraded to the j901 release, and, perhaps, when I upgraded to iOS 13.3 on both by iPhone/iPad. > On Dec 28, 2019, at 10:55 A

Re: [Jprogramming] Jhs on iPad via lan to Mac

Seems the fault lies with iOS/iPadOS safari. (It may still be a setting. ) I have reached jhs on my Mac mini via the local lan from safari on an old (2007) MacBook and from a win 10 (Edge?) system, and both behave as expected. > On Dec 27, 2019, at 7:54 PM, 'Jim Russell' via Programming > wro

Also not completely relevant to the video. It might be easier to code if using isidraw instead of isigraph because isidraw doesn't need any paint event. ymmv. On Sat, Dec 28, 2019, 10:03 PM Raul Miller wrote: > First off, thanks for putting together this video. > > That said, I can't help remini

Re: [Jprogramming] New video: building a sprite editor in J

First off, thanks for putting together this video. That said, I can't help reminisce about deciding when to render (or "paint"): Like you said in your video,ender can happen on timer, like you had it. This covers a lot of "forgot to include render after update" issues, but can get you into strang

Hi Ric, Thanks for the code. But I did not quite comprehend the phrase "special code". Do you mean that the hook (i. <./) gets replaced by some low level C code, instead of being parsed as a general hook? On Fri, 27 Dec 2019, 08:38 Ric Sherlock, wrote: > You could also use > > argminall=: 4
