Print array summaries for large arrays #45

Closed timholy closed 8 years ago

timholy commented 8 years ago

With this, you get:

julia> @noinline bar(A, i) = A[i]
bar (generic function with 1 method)

julia> foo(A) = bar(A, 2)
foo (generic function with 1 method)

julia> A = rand(1000);

julia> @enter foo(A)
In REPL[2]:1
1 foo(A) = bar(A, 2)

About to run: Main.bar
1|debug > s
In REPL[1]:1
1 @noinline bar(A, i) = A[i]

About to run: (getindex)("1000-element Array{Float64,1}",2)

which is much nicer than master's

particularly when the array has 10^8 elements rather than 10^3 elements. Even with 10^3 elements it is several screens-full.

Not a huge fan of the string quotes. How about using sth like:

immutable Placeholder
test::String
end
show(io::IO, x::Placeholder) = print(io, "<", x, ">)
timholy commented 8 years ago

I mostly expected you to say that. The definition of show you suggested will StackOverflow (print is defined in terms of show), but try this on for size:

About to run: 
(getindex)(<suppressed 1000-element Array{Float64,1}>,2)
Keno commented 8 years ago

I meant x.test or whatever I called that field ;)

Nice, I like it!
