Hyphenation of composed words

Hyphenation of composed words

[Marco]

Hi,

I've yet another hyphenation problem. I cannot get proper hyphenation in
composed words. Take this MWE:

\setuplayout [width=1.5cm]
\starttext

composed-word\par	% not hyphenated, as expected
composed||word\par	% wrong: hyphenated, but an en-dash is used,
			% not a hyphen, so [sign=wide] seems to be the default
composed|-|word\blank	% wrong: hyphenated, but the hyphen is at the start of
			% the next line

\setuphyphenmark [sign=normal]	% For hyphenation a hyphen is used,
				% not an endash
composed-word\par	% not hyphenated, as expected
composed||word\par	% wrong: hyphen is at the start of the next line
composed|-|word		% wrong: hyphen is at the start of the next line
\blank[2*line]

\setbreakpoints [compound]	% my workaround
composed-word\par	% correct hyphenation behaviour with hyphen

\stoptext

I hope with the comments the problem is clear. At first the default value for
»sign« is wrong. It has to be »normal«. But with »normal« I cannot get the
hyphen at the end of the line, instead it always appeares at the beginning of
the next line.

The workaround works but has the disadvantage that everything is hyphenated,
everywhere. I prevent this at the moment by using bars:
|not-a-composed-word|

Thanks in advance
Marco

Hi Hans,

the following code still produces an en dash instead of a hyphen.

\setuplayout [width=1.5cm]
\starttext
composed||word\par % produces an en dash

\def\compoundhyphen{-}
composed||word\par % workaroud from Thomas, produces hyphen
\stoptext

Using
ConTeXt  ver: 2010.05.08

1. || does *not* produce a en-dash but to kerned hyphens

2. The correct method to get a *normal* hyphen is

    \setuphyphenmark[sign=normal]

    If the output is not correct it's a bug.

You're right, I looked it up in the sources. It just looked like an
en-dash for me. But this is wrong. For hyphenation a hyphen is used. The
font designer has created a dedicated glyph for this purpose. And two
hyphens (or an en-dash) is too large. I've never seen the advice in a
typography book to kern two hyphens. I don't know why this is
implemented like this.

Yes, this is the correct method. It should be enabled by default. If
somebody wants a larger hyphen (for some mysterious reasen), he/she can set it
up with

\setuphyphenmark[sign=wide]

>     If the output is not correct it's a bug.
Yes, it is a bug. Hans already confirmed and said, he'll fix it, but it is not
yet done, that's why I wanted to remember him. You can try and run the example
from my first post. With Thomas' workaround the output is OK, but it is only a
workaround. I (and probably many other users) would like to have correct
behaviour by default.

because we needed it to be this way: we use it for separating compound 
words and then we want to have the hyphen between the compounds to be 
different from the ones within ... dates back more than ten years 
(educational usage) .. also, the reason for kerned hyphens instead of an 
endash is simple: the endash is too thin (at least in lm)

anyhow, when i want normal hyphens i just do |-| always

this works ok here (and i'm prety sure that it's also ok a few betas ago)

\starttext

test||test

\setuphyphenmark[sign=normal]

test||test

test|-|test

\stoptext

and the defaults are unlikely to change, but you can set it in your 
local cont-sys.tex file

That's not how it is done in everyday typography, seems to be more a
border case.

> .. also, the reason for kerned hyphens instead of an endash is simple:

That's true. The en-dash is condiderably thinner.

Sure, my fault. This works. There _was_ a bug with the hyphen appearing
on the start of the next line. This is fixed. Thank you. I thought you
would also fix the »wrong« hyphenation sign, so I didn't check, just
assumed that both issues aren't fixed. So

\setuphyphenmark[sign=normal]

works now as expected (even if it's not the default). Thanks for this
fix.

Ah, I see. I was not aware of a user configuration file (wiki helps how
to set it up I just looked). So I can put my »personal« default hyphen
there.

It seems that the en-dash *can* be used in English in some cases:
'high-priority--high-pressure tasks' from http://en.wikipedia.org/wiki/Hyphen

Concerning the hyphen sign, '\setuphyphenmark[sign=normal]' works as expected
on my system (= normal hyphen sign).
But it was (is?) not usable because, in case of a line break, the hyphen
sometimes was placed at the beginning of a new line.
With '\def\compoundhyphen{-}' the compound hyphen breaks correctly.

I see. But this is a --more or less-- contructed case where using an
en-dash instead of a hyphen makes sense. I agree with this example, the
en-dash clearifies things.

But for general purpose the hyphen is used and not the en-dash. And I
think the typesetting system should be set up to fit the general
purpose. (Hans has a different opinion, I know.)

BTW: If the appearance of the hyphen is unsatisfying it is better to
choose a different font (or hyphen from a different font) or maybe to
»correct« the font instead of altering settings of the typesetting
system.

You're right. I mixed things up. My fault. It always produced the right
sign. And the bug is fixed (Thanks Hans!). So you can use

\setuphyphenmark[sign=normal]

again in your cont-sys.tex ;-)

> With '\def\compoundhyphen{-}' the compound hyphen breaks correctly.
Not needed any more.

At the moment I use \def\compoundhyphen{-} instead of \setuphyphenmark.
It seems to work (mkii).

Yes, it works also in MKIV. This is a better workaround than mine. But
Hans said he'll fix it next beta. So I hope I'll not need it.
Nevertheless thanks for this snippet. It produces exactly the behaviour
I expect.
