Re: [Jbeta] 1.19

Re: [Jbeta] 1.19
The ~user convention is not new to this version of J and has been with J forever. ~user is used by jpath to do the lookup in SystemFolders_j_. Because J iOS is jail rooted you have the coincidence that ~user and ~/user are the same. But they get that way in very different ways. You should use ~user as that is what you would use on J on any platform.

Re the bullet button - read the simple docs. Not sure what can be done about the limited iPhone portrait landscape. I am loath to give up any of the buttons, or to make them skinnier, or to use more screen space for a different layout.

Re: [Jbeta] 1.19
Not a typo. Read the simple docs. Type abc then press bullet and you'll see _abc_, so the __ is just the case where the command name is empty. I've looked at Dropbox and it seems to be a little more trouble than it is worth. Note that with jfomurl you can easily get a file from any web site. And with tar you can get a folder just as easily as a file. The remaining problem is the upload for sharing with others. The upload is easy, but what is required is a site that runs a server that allows http post requests that manage upload of files. A JHS server could serve this purpose. For now, I am leaving these as reader exercises and will focus on trying to get J into the app store.

Re: [Jbeta] 1.19
Hi Eric, Of all the buttons, the one I think that you may be able to do without is the keyboard button. The keyboard already appears when you tap the text entry field, and it disappears when you click on the screen away from the keyboard. It is nice to have an overt way to bring the keyboard in or out, but I don't see that it makes up for the shorter space in the text entry field. It is certainly possible that I am missing some added functionality that the keyboard button provides and would love to hear if that is the case. On a second note since we seem to be wrapping up the beta, have you given any bought to including the J documentation through html as part of the download. That html window seems to me to be a natural way to provide help and not get in the way of the J text area. This is becoming even more apparent with your last 5 screen option, which means that even with graphics or plots you could use an html help and then swipe back to the graphics display. The documentation already exists on the Jsoftware site in html format so accessing via the web is a quick fix for it, but it seems to me that having documentation available even when you are off the grid is a feature (especially given the quality of the J learning materials). Just my 2 bits, you've done a great job on this beta. cheers, bob On 2012-05-30, at 7:12 AM, Eric Iverson wrote: Re the bullet button - read the simple docs.

Re: [Jbeta] 1.19
Ah HAH!
That explains an annoyance I have had for years!! Namely that ~ doesn't
work (as I would expect) in 1!:x expressions... Keeping in mind that
I've never used Windows, and always been in a 'nix environment - because
of my frustration (many years ago) I keep in my profile (start.ijs now,
thank you) the definition:
listfiles =: 3 : 'box host ''ls '',y'
which uses another ancient, heavily used definition:
box =: ;._2
and
host =: [: 2!:0 '('_ , ] , ' || true)'_
NB. Which, of course, doesn't work in iPad...
So if I enter (in a 'nix console):
listfiles '~/jstuff/hist.ijs'
+-+

$ fread ; listfiles '~/jstuff/hist.ijs'
3481
$ fread '~/jstuff/hist.ijf'
|file name error: fread
| $fread'~/jstuff/hist.ijf'
fread
1!:1@
The thing that exacerbates my confusion is the confusion introduced by
having a directory named users and in a directory named j and
accessing it with ~users rather than ~/users where ~ in 'nix
systems refers to user (home directory)
Maybe changing the name of j/users to something else (e.g. j/ulib) would
reduce my confusion, but even then it seems like broken syntax.
I confess to having always modified where the stuff appears on my 'nix
systems. For example in OS X, putting the j701x/... directory in
Documents.
If I'm the only person that has been flummoxed by this, then I'll just
accept it as another case of RTFM (except I'm unsure where to find the
explanation in jdocs Help anyone? :)
I'm just saying that maybe it is an opportunity to clear up a long time
confusion (at least on my part).

nix has a similiar convention with ~ that we borrowed. Don't remember
