After performing „install ‚all‘“, 13 packages were updated and drawing with dpoly worked in that JQT terminal (I tried it once).
I then closed the JQt terminal and reopened it, and now, the error is back - I also tried Devons advice and opened a larger dwin, but to no avail :( P.S. Is updating all packages common practice in the J world? Feels like using a rolling release linux distribution ;) > Am 22.05.2023 um 22:19 schrieb Raul Miller <[email protected]>: > > I was not able to reproduce the issue in j9.4 (nor in the j9.5 beta) > > That said, I had performed > install'all' > > before attempting. > > FYI, > > -- > Raul > > On Mon, May 22, 2023 at 1:13 PM Devon McCormick <[email protected]> wrote: >> >> I was able to get this to work by setting up a drawing window like this >> before trying "0 255 0 dpoly p1": >> >> _2 _3 2 3 dwin 'example' >> >> >> >> On Mon, May 22, 2023 at 4:09 PM Devon McCormick <[email protected]> wrote: >> >>> Trying to reproduce this error, I get a different error at the same step >>> (for version 9.4.22 on Windows 10 running JQt): >>> >>> |value error: SC >>> >>> | Y=.x:^:_1 SC 2{."1 y >>> >>> I will look into this and report what I find. >>> >>> >>> On Mon, May 22, 2023 at 4:03 PM Nils Reuße <[email protected]> wrote: >>> >>>> Hi all, >>>> >>>> I bought Part 1 of Cliff Reiters book "Fractals, Visualization and J, >>>> Fourth edition“ and am trying out the introduction examples. >>>> >>>> It first tells me to load an add-on, dwin.ijs [1], and then to create a >>>> window, which works: >>>> >>>> load '~addons/graphics/fvj4/dwin.ijs' >>>> _1 _1 1 1 dwin 'hello' >>>> >>>> Now, some data is created in p1: >>>> >>>> ]p1=: |:2 1 o./ 1r4p1*i.5 >>>> 1 0 >>>> 0.707107 0.707107 >>>> 6.12323e_17 1 >>>> _0.707107 0.707107 >>>> _1 1.22465e_16 >>>> >>>> And finally, the data is supposed to be drawn with ‚dpoly‘, which fails: >>>> >>>> 0 255 0 dpoly p1 >>>> >>>> |psel : command failed: psel >>>> : wd >>>> | (LF,~wd ::(''"_)'qer') (13!:8)3 >>>> >>>> >>>> The book states that the examples were tested with J8.04, I’m on >>>> J9.4.2/j64arm/darwin.
