I think I followed:  
[https://docs.julialang.org/en/stable/manual/workflow-tips/#A-basic-editor/REPL-workflow-1](https://docs.julialang.org/en/stable/manual/workflow-tips/#A-basic-editor/REPL-workflow-1)

but it doesn’t seem to work.

Created `Tmp.jl`  
Inside `Tmp.jl`:

```julia
module Tmp

end

```

Then started the REPL

```julia
include("Tmp.jl")

```

works fine, but

```julia
reload("Tmp")

```

produces this error:

```julia
ERROR: ArgumentError: Module Tmp not found in current path.
Run `Pkg.add("Tmp")` to install the Tmp package.
Stacktrace:

In your case, rather than calling `reload`, you can just do `include("Tmp.jl")` again.

The manual, on the other hand, is assuming that the `Tmp.jl` file is somewhere on your LOAD\_PATH and that you’ve loaded it with:

```julia
import Tmp

```

rather than `include("Tmp.jl")`.

You can read more about LOAD\_PATH here: [https://docs.julialang.org/en/stable/manual/modules/#Module-file-paths-1](https://docs.julialang.org/en/stable/manual/modules/#Module-file-paths-1)

To include your current directory in LOAD\_PATH, do:

```julia
julia> push!(LOAD_PATH, pwd())                     

julia> import Tmp

julia> reload("Tmp")
WARNING: replacing module Tmp

```

By the way, I think the manual is not very clear on this point, so I’ve opened a PR to improve it: [https://github.com/JuliaLang/julia/pull/24223](https://github.com/JuliaLang/julia/pull/24223)

Also, you can automate everything with the magical

IIRC, Revise won’t automatically track files loaded by `include`. So for a workflow involving files not in the `LOAD_PATH`, some extra work would be needed to have Revise track those files, right?

I think you are right, see  
[https://github.com/timholy/Revise.jl/issues/40](https://github.com/timholy/Revise.jl/issues/40)  
But practically, packages are so lightweight that I do all nontrivial development using one, so this is not a constraint for me.
