From bd60b6e6dde1b45c862a7cb7092e5a6985629c1f Mon Sep 17 00:00:00 2001 From: Kristaps Dzonsons Date: Tue, 25 May 2010 12:37:20 +0000 Subject: Modified version of Ingo Schwarze's patch for hyphen-breaking. Breakable hyphens are cued in the back-ends (with ASCII_HYPH) and acted upon in term.c or ignored in html.c. Also cleaned up XML decl printing (no need for extra vars). --- mandoc.c | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) (limited to 'mandoc.c') diff --git a/mandoc.c b/mandoc.c index 43ccfb21..6801c589 100644 --- a/mandoc.c +++ b/mandoc.c @@ -340,3 +340,31 @@ mandoc_eos(const char *p, size_t sz) return(0); } + + +int +mandoc_hyph(const char *start, const char *c) +{ + + /* + * Choose whether to break at a hyphenated character.
