Module aliasing in Julia

Question

In python you can do something like this to let you use a shortened module name:

>>> import tensorflow as tf

From then on you can refer to tf, instead of having to type tensorflow everywhere.

Is something like this possible in Juila?

Answer 1

Yep, you can just assign the module to a new name.

import JSON
const J = JSON

J.print(Dict("Hello, " => "World!"))

I highly recommend to use the const because otherwise there will be a performance penalty. (With the const, there is no performance penalty.)

See also github.com/JuliaLang/julia/issues/1255. This will probably have a better syntax at some point. – Explication

Answer 2

Julia now supports renaming with as.

Answer 3

I'm pushing the practical snippet @Alan don't mentioned:

• At MyMod.jl:

module MyModule

plus(x, y) = x + y
myfield = 0

end

• At Main.jl:

# Only if you're including the module from another file.
include("MyMod.jl")

import .MyModule as mymod

println(mymod.myfield)
println(mymod.plus(1, 1))
