My question is simple: When I perform an operation, I need to get a list of all the functions that get called during its execution.
For example:
```julia
function foo()
...
rand(Int32)
end
function bar()
foo()
end
```
What I want is something like:
```julia
julia> show_stacktrace(bar())
- Call to bar() with no arguments
- Call to foo() with no arguments
- Call to Base.rand(T::Type) with argument 'Int32'
- ... # <- other calls within the Julia libraries
```
I’ve read the [manual page of StackTraces](https://docs.julialang.org/en/stable/manual/stacktraces/) but didn’t understand much. The examples in that page aren’t very clear and look different from what I want.
Thanks!

The stacktrace should be obtained at the innermost point in the stack which you are interested in. Eg if you merely want to print,
```julia
@noinline function foo(x)
show(STDOUT, MIME"text/plain"(), stacktrace())
x + 1
end
@noinline bar(x) = foo(x + 2)
baz(x) = bar(x + 3)
baz(0)
```
shows
```julia
9-element Array{StackFrame,1}:
foo(::Int64) at foo.jl:2
bar(::Int64) at foo.jl:6
baz(::Int64) at foo.jl:8
....
```
Most of the complications in the example above are about pretty-printing and preventing inlining.

What if the innermost point is inside the Julia source code or an external package or something I can’t modify?
For example, for `sort([1,3,2])` I want a list of all the functions called during the execution of `Base.sort(v::AbstractArray)`.
Also, is it possible to show the arguments passed to them?

You would need to use a debugger, but that is work in progress at the moment:

You can try [TraceCalls.jl](http://nbviewer.jupyter.org/github/cstjean/TraceCalls.jl/blob/master/README.ipynb). It doesn’t work super well with Base functions at the moment; for that you may wait for 0.7 and [Cassette.jl](https://github.com/jrevels/Cassette.jl).

are there any new approaches here on simply getting a non-interactive, non-intrusive function stack trace of a method call ?
