Mixing
Does working directory change inside of a function?
I am using Julia 1.0.1 with the Juno IDE.
I wrote a module MyModule,
myModule
using Gadfly, DataFrames, Cairo, Fontconfig
function foo(N::Int64)
grid = 1:N
df = DataFrame(x = grid, y = grid .^2)
p = plot(x = "x", y = "y");
draw(PNG("figures/plot.png", 6inch, 3inch), p)
end
end
Let's call the parent directory "Top". I have a file named main.jl located in Top/Julia. I also have some auxiliary functions located in Top/Julia/functions. The script main.jl consists of the following commands:
using MyModule
include("functions/auxiliaryFunction.jl")
N = 10
foo(10)
When I run this code,
The
include("functions/auxiliaryFunction.jl")command works perfectly.The file
plot.pngis created inside the directoryTop/figuresinstead of inside ofTop/Julia/figures
If I run pwd() in the REPL, it returns ".../Top". So what appears to be happening is that the working directory in the main script is the location of the file itself (or, of the "project" in Juno...kind of confused about that), whereas the working directory of the functions it calls in the modules it imports is the working directory of the REPL. Is this correct or am I missing something? What is the standard solution to this problem - add the working directory as an argument to the function?
Edit 1: If I add
a = pwd()
println("$a")
to the script main.jl, it returns
.../Top
Edit 2: When main.jl is open in Atom, the top bar displays "main.jl --- ~/Top"

I noticed that Atom/Juno IDE can sometimes have some weird effect on the working dir. I think this has to do with the project management. Have you tried closing Juno, and restarting it by opening main.jl in the (...)/top/Julia folder? Code seems fine to me.

Tried this, it didn't seem to work. When I openmain.jldirectly with Atom after closing Juno, it looks the same as before I closed it. I do believe this has to do with project management.
