Ivar, John, thank you.
I tried to compile julia with mingw a couple weeks ago (when talking with
devs about openblas issues) and I didn't succeed, so I can't implement the
solution you point out (compilation from sources). I undesrtand the
slowness is due to repeated JIT compilation of the module/package each time
julia is called and 'using' is executed. I was looking for the existence of
some middle-way solution such as .pyc files in Python.
Another quirk: the loading time is not very important if one is using Julia
REPL-- it is imported only once; but when using the command line it becomes
annoying because its done in each run. So I tried the following: wrapping
the code for loading modules inside a function:
function mainLoad()
### code for importing modules here...
end
an then in the REPL I have an error. Apparently we cannot call "using..."
inside a function:
julia> include("timeLoading.jl")
mainLoad (generic function with 1 method)
julia> mainLoad()
ERROR: error compiling mainLoad: unsupported or misplaced expression using
in function mainLoad
julia>
Finally, to conclude, I think the more efficient way (which I'm using now)
is launching the REPL, importing only once the packages, developing
everything in the script as a function and load it with
include("script.jl")... at least in the developing stage...
Thanks again
Jose
