This does not work properly for me, as the program might run for several minutes, and it seems to me that output is only written after I flush or close the stream. But I want to see the progress in the log file (just as the REPL does) while my code runs. It would be tedious to add flush everywhere in my code where I have a print command. Is there a way to achieve this? As mentioned above I can invoke a julia session which starts another julia session with the actual code: (st,pr) = open(`$(juliaExecutable) $(juliaProgram) $(arguments)` | logFilename) Is there a way to achieve the same result without the intermediate julia session?

[julia-users] Supertypes in function arguments
I ran into a problem with types today that I don't know how to interpret.
If I define a function according to
f(x::Real) = x
it returns x as expected as long as the type of x is a subtype of Real.
However if I define
f(x::Array{Real}) = x
it throws MethodError no matter what I pass as argument. For example when I
try to pass it an Int array:
f([1 2 3; 3 4 5])
ERROR: MethodError: `f` has no method matching f(::Array{Int64,2})
I would expect it to work like
f{T:Real}(x::Array{T}) = x
and accept any array of reals. Am I missing something?
[julia-users] Re: Supertypes in function arguments
Hello Linus,
This is based on how array types are defined. In general, Vector{subtype}
is not a subtype of Vector{supertype}.
Try this:

Ok, that makes sense. In that case what would be the best way to write a
funcion that accepts several Real arrays (of not necessarily the same
type)? Currently I'm using
function f{T1,T2,T3 : Real}(x::Array{T1}, y::Array{T2}, z::Array{T3})

But that gets messy very quickly if there are many arguments.

P.S. I know that @printf basically allows the opposite of this to be done
(i.e., to write out to a file by specifying a format). Basically, my
question is if there exists the equivalent @readf to read in something that
was produced by @printf?
A quick and dirty way of doing this would be the following:
t = readdlm(filename)' # note the transpose at the end
There are a couple of issues here:
1: you'll need to manipulate the chr strings (to get rid of chr) - see
also #3, below
2: you've got an array instead of a set of vectors (easy to convert using
comprehension or other methods)
3: the array is of type {Any,2} which may lead to inefficiencies. If you
could get rid of chr before reading so that the file only contains things
that parse into numbers, the array would be of type {Float64, 2} which is
more precise, though still not 100% equivalent.
If you want to get more complicated, you could use split() and parse() to
do what you need, iterating over each line.
You could also use DataFrames to do something like this:
t = readtable(filename, separator = ' ', header=false)
but you'd still require some manipulation.
There also may be better / more clever ways, but these are the first that
come to mind.

Re: [julia-users] Julia operating mode (Juno, Jupyter)
The only option I'm aware of is to check `isdefined` for individual packages: isdefined(:Juno) || isdefined(:IJulia) || ... But doing so is not very general. Perhaps a more general question is: what capability do you want to detect? Can you define what would be the lowest-common-denominator capability represented by an `isgui()` function, analogous to `isinteractive`? There have been some similar discussions around both MIME capabilities and abstract graphics APIs. The first was resolved with the overloadable `display` design in base. For the second, the consensus was to remove the Graphics module from Base because a single abstract API could not be general enough to cover the needs of all plotting packages (now this functionality lives in the Graphics.jl package for those that use it; see also https://github.com/JuliaLang/Graphics.jl/issues/1) On Fri, Jun 26, 2015 at 9:48 AM, Josef Heinen j.hei...@me.com wrote: Can anybody tell me, how to find out, whether we are running in a simple terminal session or in a GUI environment (Juni, Jupyter, ...) ?

[julia-users] Re: matlab-like textscan function?
Thank you very much for the feedback!
Since there is no efficient textscan-like function at this time, it seems
to me that your DataFrames suggestion is perhaps the most sensible thing
for me to do, since it appears to be a package built to do things somewhat
close to my original goal (along with a lot of other statistical bells and
whistles). Therefore, I would guess it would be more efficient than the
{Any,2} array type from readdlm.
If I do end up doing more complicated things using split() and parse(), I
will post my solution back here with my code in case others come looking
for a similar solution.

[julia-users] What's the best way to implement multiple methods with similar arguments?
Hello everyone, I've just started to write a bit of code in Julia and I'm still exploring the best ways of doing this and that. I'm having this small problem now and wanted to ask for your advice. I'd like to have two methods that retrieve some items. The first method takes the max number of items that should be retrieved. And the second method takes the max item id. getitems( maxnumitems ) getitems( maxitemid ) In both cases the argument has the same type: Int. So how do I take the advantage of multiple dispatch mechanism in this situation? And is multiple dispatch really the recommended way of handling a situation like this one? Here're some alternatives that I thought of: 1. Use different function names: getitems, getitems_maxid. Not too elegant as you mix purpose and details of function usage in its name. 2. Use named arguments. This will cause the function implementation to grow (a series of if / else), again not too elegant. 3. Define a new type: ItemId which behaves exactly as Int but can be used to 'activate' multiple dispatch (one function would use Int and the second one would use ItemId). Generally not the best approach if you have methods each having an argument that should be really represented as an Int rather than a new type. 4. ...? What would you recommend ? Thank you, ks

If you are on Windows and have hit Provider PackageManager failed to satisfy dependency ... errors, please try this version and hopefully it will be fixed. To see all other bugs fixed since 0.3.9, see this commit log https://github.com/JuliaLang/julia/compare/v0.3.9...v0.3.10.

[julia-users] Re: Is ready to function returning the greater variable?
It is hard to understand your question but the function max(x,y) returns the greater of x and y. On Friday, June 26, 2015 at 12:33:34 PM UTC+2, paul analyst wrote: Is ready to function returning the greater variable? x = 1 y = 2 fun (x, y) y Paul
[julia-users] error while trying to plot a graph when using Graph.jl and GraphViz.jl
Hello,
this is the procedure I'm following:
*Pkg.add(Graphs)*
*using Graphs*
*Pkg.add(GraphViz)*
*using GraphViz*
*g=simple_graph(3)*
*add_edge!(g,1,2)*
*add_edge!(g,3,2)*
*add_edge!(g,3,1)*
*plot(g)*
and this is the error I get:
*julia **plot(g)*
*ERROR: `to_dot` has no method matching

I am trying to follow the instructions shown here http://julia.readthedocs.org/en/latest/manual/embedding/. First things first, I run Ubuntu 15.04 and my Julia version is v. 0.3.2 (it's the version that is automatic installed when installing julia from ubuntu center). I use eclipse for my C++ projects, yet again I have the following issues, ac- cording to the instructions before trying to write any julia code in C or C++ you need first to: 1) link the julia library (assuming I undersand correctly this refers to libjulia.so), which should be located in Julia_DIR/usr/lib, yet again in my julia directory there is no folder under the name usr. I did though find a libjulia.so file in an other directory of my pc (/usr/lib/x86_64-linux-gnu/julia) and added this one instead. 2) include the path of julia.h which should be located in Julia_DIR/inclue/julia now again in my julia directory there are no such folders and in general there is nowhere in my pc any file such as julia.h. I did sth that is probably wrong and stupid but couldn't come up with anything else I downloaded this https://github.com/JuliaLang/julia and I included the location of where julia.h is located to eclipse as well with the direc- tions of all the other header files that were inculuded inside julia.h. Now when in Eclipse I am trying to compile and run a few simple julia commands having included julia.h i receive an error saying that there is no uv.h file in my system which is needed in one of the julia header files. I know that my whole approach is wrong, but yet again I couldn't find anywhere in my pc the proper folders or files in order to follow the steps that were sugges- ted in the julia website for running julia code inside C++. Any help would be much appreciated. Also, one more thing I wanted to ask is the following, in general writing Julia code inside a C++ code is limited? What I want to do in general is write a JuMP model inside C++, so in general is this possible, in the sense that by embedding Julia inside C++, will I be able to use all of the tools and code of Julia language or is this only limited to a cer- tain amount of commands and packages?
