feat(printer): reader-macro sugar in Pr_data#124
Merged
Conversation
Pr_data now prints reader-macro expansions with their sugar instead of the underlying call: (quote x)->'x, (quasiquote x)->`x, (unquote x)->~x, (splice-unquote x)->~@x, (deref x)->@x, and (with-meta form meta)-> ^meta form. Width-aware wrapping still applies (a long '[...] wraps with the form aligned under the prefix), and the forms round-trip: the reader re-expands the sugar to the same value. This makes .state files (which serialize via Pr_data) read naturally. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
