Author: G. Branden Robinson <[email protected]>
AuthorDate: Tue Feb 4 05:36:08 2025 -0600
[troff]: Add experimental charinfo dump feature.
* src/roff/troff/charinfo.h (class charinfo): Declare `dump()` member
function, taking and returning no arguments.
* src/roff/troff/input.cpp (charinfo::dump): Implement it.
(report_character_request): Add request handler that iterates each
ordinary or special character in the argument and calls `dump()` on
it.
(init_input_requests): Wire up `pchar` request to handler.
