Hello Guys,
This is my first post on this forum and I take the opportunity of this
question to wish you the best for this new year 2021.
As a means of learning J I'm trying to implement my "standard"
application with it. This app reads a text file and feed a database
which I query to get various metrics. I also want to have a some data
displayed in a terminal with an automatic update when the source file is
modified or when the day changes. Simple, isn't it?
In order to achieve this I thought to use a "while" loop with a kind of
"wait/sleep" function like this foreign verb "6!:3". But unfortunately
the result is not the one I expected as it looks like the display is
locked until the loops ends.
I have a question on Stackoverflow here
https://stackoverflow.com/questions/65532824/j-programming-how-to-wait-fo-x-seconds-before-executing-the-next-verb
but I'm still looking for a solution.
Hence here is my question: is there any way to have a "while" loop which
doesn't hold the entire verb ?
here is my verb in pseudo code:
agenda : 3 : 0
echo (something)
while. (test for file ok)
do. (wait for 20s)
end.
(update data base)
agenda''
)
Any idea?
Regards
Eric
