Interesting. I am running Julia 0.2.0 and both of the following seem to be working for me, whether I evaluate the function or not:
f(x,y) = x + y
and
function f(x,y) x + y end
That would suggest that, whatever the problem is, it is either with some change introduced to julia after 0.2.0, or maybe there's something spooky about your function that is triggering a problem not caught by my toy example.
I haven't updated to julia 0.3.0 because I haven't yet managed to get my gentoo ebuild to compile without error. If you find out that the problem is associated with the newer julia, then please let me know and I'll see if I can get my julia updated and try to track this problem down.
Thanks for the report.
I'm guessing it's a 0.3 issue; I have the same problem with your examples above. Furthermore, it's not limited to function definitions -- I tried this example from the documentation:
#+BEGIN_SRC julia
using Winston
x = linspace(0, 3pi, 100)
c = cos(x)
s = sin(x)
p = FramedPlot();
setattr(p, "title", "title!")
setattr(p, "xlabel", L"\Sigma x^2_i")
setattr(p, "ylabel", L"\Theta_i")
add(p, FillBetween(x, c, x, s) )
add(p, Curve(x, c, "color", "red") )
add(p, Curve(x, s, "color", "blue") )
#+END_SRC
which results in a similar error:
ERROR: no method start(FramedPlot)
in writedlm at datafmt.jl:534
in anonymous at datafmt.jl:549
in open at io.jl:373
in writedlm at datafmt.jl:548
in writecsv at datafmt.jl:554
in _start at ./client.jl:393
On the other hand, this example does work:
#+BEGIN_SRC julia
rand(2,3)
#+END_SRC

I don't know if it's related, but it appears that Julia 0.3 no longer includes a separate julia-release-basic
executable, so I set inferior-julia-program-name
to point to the julia
executable, which seems to work OK for an ESS julia session at least. If I have time today I'll try the 0.2 release to verify that this is a 0.3 issue.
Well, I confirmed that it does work for me with the julia 0.2.1 release. On top of that, it's now working after switching back to 0.3. Sorry about the false alarm; it's obviously something on my end...
First, many thanks for creating ob-julia. Is it possible to have just a julia function definition in a code block, to be called later in a separate block? I get the following error from executing a code block containing only a function definition:
If I add a call to the function as the last line in the block, it evaluates successfully and outputs the results block. I'm running juila 0.3.0-prerelease+3921. Any suggestions?
