To run Julia, first get the interpreter from the website’s download page. The current stable release is v0.5.0, and this version is recommended for most users. Certain package developers or power users may choose to use the nightly build, which is far less stable.
When you have the interpreter, write your program in a file named
hello.jl . It can then be run from a system terminal as:
$ julia hello.jl Hello, World!
Julia can also be run interactively, by running the
julia program. You should see a header and prompt, as follows:
_ _ _ _(_)_ | A fresh approach to technical computing (_) | (_) (_) | Documentation: http://docs.julialang.org _ _ _| |_ __ _ | Type "?help" for help. | | | | | | |/ _` | | | | |_| | | | (_| | | Version 0.4.2 (2015-12-06 21:47 UTC) _/ |\__'_|_|_|\__'_| | Official http://julialang.org/ release |__/ | x86_64-w64-mingw32 julia>
You can run any Julia code in this REPL, so try:
julia> println("Hello, World!") Hello, World!
This example makes use of a string,
"Hello, World!" , and of the
println function—one of many in the standard library. For more information or help, try the following sources:
