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 @infiltrate
macro.
# 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.
julia> include("debugging.jl")
julia> include("debugging.jl")
Infiltrating calcs(x::Int64, y::Int64) at debugging.jl:10:
infil> @locals
- a::Int64 = 83
- y::Int64 = 9
- x::Int64 = 2
infil> x
2
