Decompiling AST

[slyons]

Not exactly the best title, I know.

Is it possible to take an AST and turn it back into Source? Not the exact formatting or anything like that, just turn it back into the source code. I have an experiment where I'm modifying the AST and want to show it back to the user.

Not easily as Rhai's AST does not contain all the contextual information required to reconstruct a source text.

Mainly this has to do with the switch statement but things like custom syntax etc. are also troublesome.

That's why the compression feature uses token manipulation instead of writing out and AST as text.

If you're willing to be only about 80% of the way there, then it is not difficult to write. You just have to be careful about parentheses.
