Is there any built-in function for human-readable F# quotations?

Question

When quoting

<@ 1 + 1 @>

I want "1 + 1"

instead of

"Call (None, Int32 op_Addition[Int32,Int32,Int32](Int32, Int32), [Value (1), Value (1)])"

Answer 1

You'll have to write it yourself. See the F# quotations visualizer code as a guide for transforming the quotations abstract syntax tree.

Answer 2

There is none, and it's not quite that easy, except in very simple cases. One of the main problems, for example, is the match construct. It is syntactic sugar for a whole bunch of if and switch statements (try printing a quotation with a match in, you'll see). Another one of those biggies are computation expressions, but I guess you could skip those at first.

Then there is a the rabbit hole of ambiguities you'll have to resolve, with conventions like the pipe operator starts a new line, let starts a new line, indentation, infix, prefix, special cases like the (::) operator and so forth.

All in all, doable, but not trivial. Sort of like decompiling.
