I'm looking for a verb to flatten every J data to a single character string,
with the same display.
I've found that the verb flatten (defined in format.ijs) does not work
properly with some arguments (when rank of y is >2); example:
load 'format'
]myarr=: ,:('Hello',LF,'World'),:'bye'
Hello
World
bye
flatten myarr
Hello World
bye
I think this happens because there is a boxing inside the verb, where LF is
lost.
My current solution (to be improved and tested) is:
myflatten=: 3 : 0
r=. _1
y=. ,&LF"1 ": y
while. 2 < # $ y do.
r=. <:r
y=. (,&LF)@,"2 y
end.
r }. ,y
)
