source§fn print_tt(&mut self, tt: &TokenTree, convert_dollar_crate: bool) -> Spacing
fn print_tt(&mut self, tt: &TokenTree, convert_dollar_crate: bool) -> Spacing
This doesn’t deserve to be called “pretty” printing, but it should be
meaning-preserving. A quick hack that might help would be to look at the
spans embedded in the TTs to decide where to put spaces and newlines.
But it’d be better to parse these according to the grammar of the
appropriate macro, transcribe back into the grammar we just parsed from,
and then pretty-print the resulting AST nodes (so, e.g., we print
expression arguments as expressions). It can be done! I think.
