Another +1 for Nullable type as opposed to Option type.
Option type does not convey any specific meaning.

Let me add a thought here. I also think that adding a row to a dataframe
should be easier. However, I do not think that an array would be the best
container to represent a row because array members must all be of the same
type which brings up Any as the only options in your example.
I think
Or may I suggest simply calling Pkg.available() in the Julia REPL directly.

Yes, but unfortunately, the piping operator, |, can only be applied to
functions taking a single argument. I really wish it could be applied to
functions of any number of elements.
Did I miss a link in your post?
Is there any place to interact with or see your progress online now?
Good luck in your endeavour
I did see that post after but I still fail to see the connection between
the two.

I posted a similar question a week or 10 days ago without a reply. I am
giving this a try again.
I was able to get the call to work at home with something like the
following: When I would change the file println's below would display the
information in the console. However, I had no access to
Ok, I figured it out:
julia wf = watch_file((fn, ev, st) - begin
println(File Name : *string(fn))
println(Event : *string(ev))
println(Status: *string(st))
end,
c:\\Bits\\watch.txt)
FileMonitor(Ptr{Void}
Amen to that!
So what is the state of things? Still no luck on Windows for me this
morning.
I did Pkg.update(), Pkg.checkout(ZipFile), Pkg.build(TestImages) in
various combinations and got the same results, no download.
I looked in the presumably updated build.jl file, I still see the same call
to
Ok, I'll do that tomorrow.
I had diagnosed that the problem was with the download function myself and
I put some println statements in there to see at which precise point it was
failing but none of those ever appeared so I was a little confused.
Now that you say it is not available on Windows, it makes sense. So I am
Replying to myself. The exports are in share/julia/base/exports.jl and the
download function is exported for all platforms.
So I guess what you meant was that it simply does not work on Windows.
Thanks Avik.
So should this not be reported as an issue? Not the problem with this
package but the fact that the standard library function download is not
supported on Windows.
Is it an issue already?
Here it is running the pertinent lines in the REPL.
It seems like the download does not work I think.

I am reading the code in the Pkg internal package. In there, I see a
function, genfile defined with the prototype below.
function genfile(f::Function, pkg::String, file::String, force::Bool=false)
This is the only definition of a genfile function/method I can find in all
of Julia's source
As I understand it, for any given n, ModInt{n} is a different type.
The type knows about n but n is not a slot in the type. The type only has
one slot, k.
So you can't have a constructor with two parameters as you are declaring it.
Ah! The world is right again.
Now that you point me to it, I remember reading it. I guess it had not

Sincere thanks.
I am going through the standard library documentation and trying out
various functions to make myself familiar with them.
I tried the watch_file function to which you provide a callback function
that is called whenever the file changes. The question I have is how do I
stop watching? Of course

I am taking a look at your package this morning. A couple of issues to get

I guess this package is not for me. It does not seem to be meant to be

As I look at the errors more closely as I am posting this, I see your

Windows 7 compatible?

Ethan,
You do not even need to do that. In fact, it is a bad idea.
If you just want to simulate randomly without being able to reproduce the
result, do away with the seed.
If you need reproducibility then you need to know the seed. In that
case, that random draw is not helping you either
Sorry, I had missed the point that you were storing the randomly generated
seed.

I forgot to say that in addition to seed = rand(1:1) I then do
srand(seed)...which does allow me to reproduce the results. As I was
saying,
What is it that you are trying to do? You don't need to call stand with a
mysterious number. Pick your favorite number
srand(53)
and do your thing.
If you want to change your model but use the same seed, you know it already.
If you want the same model with a different seed, just pick 67 or
Fil,
Isn't the problem simply that you are defining a function that takes no
parameters yet you assert that this non existant parameter is of type T?
That does not seem like a good idea.

When you say there is no such thing, you probably mean it is not common or
perhaps not idiomatic.
However, there is no technical reason to not being allowed to have a field
of type Function.
