README file for the nohyphb and nohyphbc hyphenation patterns.
--------------------------------------------------------------

These patterns are generated from a collection of 750000 Norwegian
words taken from both variants of the Norwegian language (bokmål and
nynorsk).  They should work on every word in the list they are
generated from.  This dictionary together with scripts to make it
usable with ispell and scripts to generate these patterns are
available from

http://www.uio.no/~runekl/dictionary.html

The nohyphb patters hyphenates Norwegian text as TeX used to, for
example `barne-hage-as-si-stent'.  The nohyphbc hyphenates only
between compound words, e.g.  `barnehage-assistent', `barne-hage'.
This is good for ragged text or very long lines.

These patterns will not fail on common words, e.g. words in the
dictionary.  If they do it is a bug.  The old Norwegian patterns
failed on many common words.  Proof is on the web page above.  But
even if these patterns are of high quality, they still might fail on
Norwegian words not in the dictionary, so if you don't feel
particularly lucky you will have to do something about that too.

There are two strategies.

1. Mark the compound point in the compound word with "-, e.g.
   administrasjons"-sjef"-stillings-"søker.  If you have patched
   ispell with the patch from my web page, you can do this during
   spell-checking most of the time.  I dislike this approach.
   
2. Install the Norwegian dictionary from the web page above and Use
   the script inorsk-hyphenmaybe to print every word in your document
   not in the dictionary (nynorsk and bokmål) hyphenated by TeX.  Then
   you can easily browse through this list and put the badly
   hyphenated words in a \hyphenation command.  The next time you run
   the script (and TeX) it should produce correct hyphenation.
   
   For example if inorsk-hyphenmaybe outputs `kon-flik-t-akse' and
   `kon-flik-t-ak-sen' you have to say \hyphenation{kon-flikt-akse
   `kon-flikt-ak-sen'} in your TeX document.

   This approach can also help you if you have lots of foreign words
   in your documend and don't want to use \foreignlanguage from Babel.


There are two things TeX still cant do regarding hyphenation.  It
can't hyphenate `villede' automatically as `vill-lede'; you need to
say `vi"llede' if you have Babel-3.7.  If you don't have Babel-3.7 I
recommend norsk.cfg available from my web page.  However, the
patterns will not fail on these kind of words, they will only miss a
possible hyphen.  And by the way, the ispell dictionary from my web
page accepts the spelling vi"llede.

The second thing is multi level hyphenation, e.g. different penalties
for different hyphen points.  The scripts available from my web page
makes it possible to generate patterns for a TeX that can do this, and
the change files by Matthias Clasen that used to be available from 

ftp://peano.mathematik.uni-freiburg.de/pub/etex/

makes it possible to build such a TeX.  If they aren't availiable from
there, look in

http://www.uio.no/~runekl/clasen.tar.gz


If you want to install both sets of Norwegian patterns in the same
format, you have a TeX capacity problem.  The variable ssup_tree_size
needs to be bigger than 65535 and trie_op_size bigger than 1501.  I
use 262142 and 3501.  So you need to change tex.ch (and omega.ch) and
recompile TeX.  If you are using teTeX that should be quite easy.
Here is an unsupported patch:

The easiest way to use both sets of patterns in the same document is
to define the macros

\def\goodhyphens{\lefthyphenmin2\righthyphenmin2\language=\l@norskc}
\def\allhyphens{\lefthyphenmin1\righthyphenmin2\language=\l@norsk}

and change hyphenation whenever you want to.  In this case the
language.dat file should contain the lines

norsk          nohyphb.tex
norskc         nohyphbc.tex
