[julia-users] Type matching in Julia version 0.4.0-dev+3434

Hi, I have just updated Julia for the first time in 10 days and now I face problems with old code: - The error "WARNING: [a] concatenation is deprecated; use [a;] instead". Easy to fix, but what is the reasoning behind adding the ";"? - Type matching has changed: I have a function that takes a

Hi, I would like to write floating point numbers to a file and limit the number of digits/decimals. With e.g. f = open("test.txt", "w") println(f, 1/3) close(f) test.txt contains 0. and I would like it to be only 0.33. Is there a way to do this? Thanks, Robert

Hi, I have a situation where a number of functions differ so little that it would make sense to define them by a loop. I don't know if I am using the correct jargon, but here is a small example to illustrate: type test A::Int B::Int end function A(T::test) T.A end fun

You can take a look at a package to get inspiration: One master file includes all the other files with code and load any 3rd party dependencies. You then include the master file in Julia to have all of your functions available. On Thursday, February 4, 2016 at 6:33:35 AM UTC+1, Cristian Garcia

That kind of reloading/recompilation would definitely be nice, but in my example I just change one function that does not depend on anything else. If I reload the package shouldn't I then get the new version of the functions in the package?
