in repository groff.
commit 9a1933c09d8aed86724aed5ee7be170e22ead56f
Author: G. Branden Robinson <[email protected]>
AuthorDate: Fri Jun 6 14:30:36 2025 -0500
[grops]: Trivially refactor.
* src/devices/grops/ps.cpp
(class ps_font)
(struct subencoding)
(struct style)
(class ps_printer): Comment member function formal argument names as a
compromise with the Stroustrup-style C++ used in most of groff.
(main): Spell null pointer constant the idiomatic C++98 way (`0`)
instead of as `NULL`.
(ps_font::handle_unknown_font_command)
(handle_unknown_desc_command): Rename argument from `filename` to `fn`
to preëmpt `-Wshadow` compiler warning with planned refactoring of
`class font`.
