Suppress warning about conflict with existing identifier

Question

I'm starting REPL and then using include("./main.jl") multiple times to speed up script loading.

After the first run it starts giving warnings:

WARNING: replacing module Lib.
WARNING: using Lib.somefn in module Main conflicts with an existing identifier.

How to suppress it?

Answer 1

You should use Revise and then includet("./main.jl") (note the 't' at the end of includet, standing for "track"). From there on, whenever you make a change to file "main.jl", these changes are reflected in the REPL, without warning.

Example:

• File main.jl:

module Lib

somefn() = 42

end #module

• REPL:

julia> using Revise
julia> includet("main.jl")
julia> Lib.somefn()
42

# modify the definition of somefn in main.jl and save the file

julia> Lib.somefn()
43

NB: If Revise is not already installed on your system, you might have to install it first:

julia> using Pkg
julia> Pkg.add("Revise")
