Does Julia have an equivalent to Python’s
if __name__ == "__main__": ...
Specifically, my problem is the following. I’m writing a standalone Julia script
run_simulation.jl that does some computation and will ultimately run on a cluster. All the code in the script is in functions, including a function
main(args), and the only line in the script that actually runs code is the last line
Now, during testing on small datasets, I’m getting a bit annoyed at the JIT-overhead. So, I’d rather run an interactive julia session, and do e.g.
julia> include("run_simulation.jl") julia> main(["./runfolder"])
Then I can repeatedly run
main without Julia recompiling.
This works if I comment out the last line of the script, but out of curiosity: can Julia detect whether it’s running as a script and should execute the
main function, or whether it is
included in the REPL (or another file)?
