Source location for a type definition from utop
1
In utop, can I get the source location for the definition of the type, say, result ?
utop # #show_type result;;
type nonrec ('a, 'b) result = ('a, 'b) result = Ok of 'a | Error of 'b
(defined in pervasives
Result type
type ('a, 'b) result =
| Ok of 'a
| Error of 'b
Since 4.03.0
but I am not sure how to get that info systematically)

The least you'd need for this to work is to compile OCaml with the-g(debug) flag. This will add source information in the compiled binaries. But even then, I'm not sureutopknows how to use such information.

Not really an answer to your question, but do you know you can get this information using merlin with emacs, Vi or VisualStudio ?

May be that is the best answer. I tend to be fearful of too much editor integration out of experience of haskell tooling being brittle, but merlin seems really sturdy and emacs mode is a joy. Do you use utop from the editor integration mostly ?

I had trouble integrating utop with tuareg mode, probably due to an emacs init files cluttered with legacy tuareg-mode tweaks, so I use the standard REPL. But really, I use less and less the REPL as tuareg-mode+merlin gives me the type of everything, and tells me if it compiles or not, which is most of the time what I used the REPL for.
