I’m trying to wrap my head around formatters and tried reading all of these with varying degree of success:
https://cedeela.fr/format-all-the-data-structures.html
http://caml.inria.fr/pub/docs/manual-ocaml/libref/Format.html
http://erratique.ch/software/fmt/doc/Fmt.html
I am still not sure how to address my actual problem…
I have parsed lines, which (for the sake of example) look something like this:
type fruit = Apples | Oranges
type quantity = (int * fruit)
type ast_line = {name: string;
quantity: quantity option;
comment: string option}
I’d like to be able to print something like this (note the padding)
Alice 5 apples // some comment
Bob 5553 oranges // some comment
Charles // some comment
Of course, I know how to do that by calculating lengths of strings, but I suspect there is a better way by using some of these libraries, though I can’t figure out if they do provide the needed tools.
