There seems to be a great deal of it... The things I'm having trouble
locating:
1) How to get information on functions available in a julia package, usage,
etc
2) A good lightweight graphics package for such simple-minded tasks as a 2D
game board with round pieces on a square grid.
3) The bes
On the unpacking issue, rather than put x into a (C type) union, it might
be faster with something like so:
function unpack(x)
x4 = x & 65535
x3 = ( x >> 16) & 65535
x2 = (x >> 32) & 65535
x1 = (x >> 48) & 65535
return x1, x2, x3, x4
end
but I'd sti
Finding Cairo to be reasonably well-documented with examples, and already
installed,
I did 'using Cairo' and then typed in "set_source_rgb(0, 0, 0)" --
with the result: "error -- no method for int64".
"help" tells me that yes, "set_source_rgb") is a function, and has two
methods.

rrrgh!!!
99.9% of the warnings are about syntax being used within the v4 tc
package!!!
Can I suppress these & get on with it?

Thanks, all!
Most of my booboos seem to be due to the fact that julia doesn't like
'foo ()'
anymore, she now prefers 'foo()' which I suppose makes the parsing simpler.
And I now know where to find that pesky tk button code...

I have the latest julia version installed on ubuntu and debian partitions
on my hard drive.
On the ubuntu, I can type [for example]:
julia --depwarning=no newbox.jl
and that file loads, runs, exits.
On the debian, julia comes up in REPL mode and my file seems unrecognized.
(Likewise if I stay in
still needed(?))
What's gone wrong with simply running a script from the command line?

I've since found a better approach which I'm going to post as a new topic!
I was having trouble importing a certain python module into julia for
realtime interactions...
and painfully worked out what looks to be a good general rule-of-thumb:
Write your own module (and put it into python's path) in which you don't
try to do anything complex that would require figuring c
The amount of glue I needed to write was minimal, considering that I didn't
want to have to decide how much of the time a routine would devote to
listening on a port, nor how many messages might be received between calls,
nor how to get a list of these into julia.

Um, better to add the part about methods, that you need the concluding '()'
so that julia will recognize a method as a function.
It is simply very difficult to explain anything whatsoever you have
