Re: [Jgeneral] Finding details of value structure - script
Well, here's how I did it: (1) I visited code.jsoftware.com (2) in the search box, I entered: file:CTScan.ijs and completed the search. This took me to the page https://code.jsoftware.com/wiki/File:CTScan.ijs which included download links for the file. (3) I downloaded the most recent version of the script to my j902-user directory, using right click save-link-as It would be more convenient, I imagine, if there were a wiki page that linked to the script. Another possibility, though, would be to put the script up on github as Henry suggested while I was composing this email. See also: https://code.jsoftware.com/wiki/Addons/GitHub (though a code.jsoftware.com wiki page for it could still be nice.)

Make your script an Addon. Then users will get it automatically through Package Manager. You will need a GitHub login.

Re: [Jgeneral] Finding details of value structure
Or, you could do
user=: ;getscripts_j_ '~user'
But, fortunately, this is unnecessary. The only time this script
accesses that value is when CTScn is not defined, but this script
defines that name.
So, really, it's just an opportunity for code cleanup.
FYI,

[Jgeneral] searchable mailing list archive
Hello, is it so that the mailing list archive http://jsoftware.com/pipermail/programming/ is really not searchable? If that's the case, it's a pitty. (E.g., OpenBSD, emacs org-mode, plan9 fora are all [at least to some extent] searchable...) (I was thinking about reducing the volume of messages that I keep in my mailboxes, and it occured to me that it's strange that each person should keep a copy of messages that went to a mailing list just to be able to search through it.) Thanks for comments. Do you actually keep all the messages? Ruda -- For information about J forums see http://www.jsoftware.com/forums.htm
[Jgeneral] Finding details of value structure
Apology--I have just uploaded a correction to CTScan.ijs, to fix a late
"improvement" which derailed processing of an empty argument (as in the
earlier-run example).
Note--The verb name, chosen for elegance and to minimize conflict, is also
supplied with a more convenient nickname, cts, which appears in only one other
usage in a wiki search.

Re: [Jgeneral] Finding details of value structure
Hi Arthur,
I was looking at CTScan and I noticed that on line 5 you define
user=: '/Users/ala/j64-807-user'
which would be constant to your system. If you define
user=: 4 }. ; (#~ (<'User') = {."1) UserFolders_j_
then the value of user can be specific to the system of the person running it,
as UserFolders_j_ is set up in the loading of the J environment.
Also, I was wondering if you could include a CT option that would stop the
display of depth and level values of the structures because that information
seems to be apparent through visual inspection. The shape and type of the
contents are the ones that I think are essential and leaving off the depth and
level would free up space for them and that may be important when dealing with
narrow boxes. When I was working on jig, Raul and Pascal put me through my
paces of removing any information that did not need to be displayed. A few
things I left in, but usually if they said it was not necessary they were
right.
What are your thoughts on providing a CT option to remove the depth and level
values?
Cheers, bob
