G'day
I did fresh installs of j901 and the latest j902 (with DD) on my new Ubuntu
installation (20.04).
In j902 the much appreciated math/calculus package does not seem to work.

Yes.
Thank you,

I can give you multiline noun DDs but the contents must follow J word
formation and fit into the DD syntax. In other words, if {{)n contains
other {{, they are going to be treated as starting nested DDs.
This will be adequate for the example you gave, and for most uses I expect.

O
Nice, thank you.
That said one line noun DDs by themselves are silly. But they
would address an issue with nested quotes -- so they would not be
entirely silly.
Thanks again,

Not picking up : inside {{ }} is a bug. It looks for the : but then
forgets to set the type to 3 instead of 4.
When I started the implementation it was impossible to have LF in a
quoted string inside an explicit definition, which made it impossible to
do multiline noun DDs, and one-line noun
Ah, I see... or )a or )c decorators.
I am sort of disappointed that I can't build nouns this way. (Or, at
least, I haven't figured out how, yet.)

I think it would be nice to be able to do
Raul,
You need the )v decorator. Try the following:
f=: {{)v

:
x+y
}}

One thing I am hoping for (and/or looking forward to) is some way of
providing both the monadic and dyadic verb definitions.
Specifically, in j902-beta-i:

status of rpi 64, but we do intend to be there when the time is right.

Installed and works nicely in OSX.
Any chance of having a Raspberry Pi build for this beta? Also, are there any
plans for a 64 bit Pi version?

... forgot to say my problem was in Windows 10, updating from J902-h, I think.
I’ve managed to reinstall successfully using the zip-file.

I've been away for a few days and DD drops.
One thing I immediately approve of is how this will cut down on one of my
most despised

My update went smoothly on j902 (and the shortcuts even worked now that I have
straightened out my previous fuzzy thinking!)

Similar to Pascal Jasmin, I think, j901-i won’t load. Here’s a précis of the

possibly as a result of clicking updateje command prior to running updatejqt

DirectDefinition is a significant new feature in J902-beta-i.
DD is a new way to define verbs/adverbs/conjunctions that we think is a
worthwhile improvement over n :
f=: {{x+y}} NB. f=: 4 : 'x+y'
2 f 3
5
2{{x+y}}3 NB. 2(4 : 'x+y')3
5
The power of DD is clearer with multiple lines a
16 matches
