From be78d187113a40c88e1dcc5736895148247a9600 Mon Sep 17 00:00:00 2001 From: wlemb Date: Sat, 25 Jan 2003 16:57:40 +0000 Subject: Add US-english hyphenation exceptions (converted from Barbara Beeton's hyphenation exception log reports which appear irregularly in TUGBoat). * tmac/hyphen.us: Updated to latest version. * tmac/README: Updated. * tmac/hyphenex.us, tmac/hyphenex.sh: New files. * tmac/troffrc: Load `hyphenex.us'. * tmac/Makefile.sub (NORMALFILES): Add `hyphenex.us'. * doc/groff.texinfo: Updated. Improve hyphenation slightly. This is a first step in redesigning the hyphenation algorithm to make it more flexible (e.g. allowing kerns and ligatures between the hyphenation character and the following character -- while not used normally in English, other languages like German would benefit). * src/roff/troff/env.cc (environment::hyphenate_line): Use assertion instead of if-clause. Let `get_hyphen_list' return the number of involved characters in the hyphenation pattern instead of computing it directly (which often yields too small values). * src/roff/troff/node.h (*::get_hyphen_list): Add second parameter. * src/roff/troff/node.cc (*::get_hyphen_list): Handle new second parameter. Fixing a bug which caused groff to hang if the hyphenation exception dictionary tried to grow. * src/roff/troff/env.cc (hyphen_trie::insert_hyphenation, hyphen_trie::read_patterns_file, do_hyphenation_patterns_file): Use pointer to dictionary. --- tmac/hyphen.us | 3 +++ 1 file changed, 3 insertions(+) (limited to 'tmac/hyphen.us') diff --git a/tmac/hyphen.us b/tmac/hyphen.us index 26a4332d..86e113cf 100644 --- a/tmac/hyphen.us +++ b/tmac/hyphen.us @@ -1,4 +1,7 @@ % The Plain TeX hyphenation tables [NOT TO BE CHANGED IN ANY WAY!] +% Unlimited copying and redistribution of this file are permitted as long +% as this file is not modified.
