Include error: no such file or directory

[gbruer15]

sandbox() sets include() to always be relative to the example file. Is there a reason for this? I have a use case where I'd like to include a file from a different directory that includes another file, so I get an error when running with Literate.jl even though the script runs fine on its own.

Here is a minimum failing example:

Here are the files:

$ ls mfe
example.jl utils
$ ls mfe/utils/
utils.jl  utils_A.jl
$ cat mfe/utils/utils_A.jl 
A() = println("Hello")
$ cat mfe/utils/utils.jl 
include("utils_A.jl")
$ cat example_direct.jl
include("utils/utils_A.jl")
A()
$ cat example_indirect.jl
include("utils/utils.jl")
A()

Running normally works fine.

$ julia mfe/example_direct.jl
Hello
$ julia mfe/example_indirect.jl
Hello

Running with Literate.jl fails with the indirect include:

A quick fix for this is to put this code at the top of your example script:

include(x) = Base.include(@__MODULE__, x)
let
    s = current_task().storage
    if !isnothing(s)
        s[:SOURCE_PATH] = @__FILE__
    end
end

It sets include back to the standard form and sets the source file for include to be the current source file.
