Cthulhu.jl
The slow descent into madness
Cthulhu can help you debug type inference issues by recursively showing the
code_typed output until you find the exact point where inference gave up,
messed up, or did something unexpected. Using the Cthulhu interface you can
debug type inference problems faster.
descend(f, tt)
@descend f()
Given a function and a tuple-type, interactively explore the output of
code_typed by descending into invoke and call statements. (invoke
statements correspond to static dispatch, whereas call statements correspond
to dynamic dispatch.) Press enter to select an invoke or call to descend
into, select ↩ to ascend, and press q or control-c to quit.
Usage
function foo()
T = rand() > 0.5 ? Int64 : Float64
sum(rand(T, 100))
end
descend(foo, Tuple{})
@descend foo()
