From bfb452504d8b3a8d83033a92009dcdba6370788c Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Fri, 2 Jun 2017 19:21:23 +0000 Subject: Partial implementation of \h (horizontal line drawing function). A full implementation would require access to output device properties and state variables (both only available after the main parser has finalized the parse tree) before numerical expansions in the roff preprocessor (i.e., before the main parser is even started). Not trying to pull that stunt right now because the static-width implementation committed here is sufficient for tcl-style manual pages and already more complicated than i would have suspected. --- mandoc.c | 14 ++++++++++++-- 1 file changed, 12 insertions(+), 2 deletions(-) (limited to 'mandoc.c') diff --git a/mandoc.c b/mandoc.c index 03c25e0d..5f57801d 100644 --- a/mandoc.c +++ b/mandoc.c @@ -1,7 +1,7 @@ /* $Id$ */ /* * Copyright (c) 2008-2011, 2014 Kristaps Dzonsons - * Copyright (c) 2011-2015 Ingo Schwarze + * Copyright (c) 2011-2015, 2017 Ingo Schwarze * * Permission to use, copy, modify, and distribute this software for any * purpose with or without fee is hereby granted, provided that the above @@ -175,7 +175,17 @@ mandoc_escape(const char **end, const char **start, int *sz) ++*end; return ESCAPE_ERROR; } - gly = (*start)[-1] == 'h' ?
