One way to debug Julia code is to use the Infiltrator.jl package. As shown in the example file below, a breakpoint is set with the
# debugging.jl using Infiltrator function calcs(x, y) a = x + y^2 @infiltrate b = (a + 3) / x^2 return b end z = calcs(2, 9) println("z is $z")
To debug the file, open a Julia REPL then run the file in the REPL to enter the debugger mode
infil>. View a list of local variables in the debugger with
@locals or use
? to see the other available commands. Local variables can also be viewed and manipulated by just entering them into the debugger REPL.
