Hello again, it's been a while... ;-) I need to pack fixed lines into a fixed width box. Some years ago I had something similar in plain PostScript, where I pre-calculated the width of a text box, let the default font if it would fit my max size, otherwise try a narrow font and if that wasn’t enough decreased font size until it would fit. This time I've only one font and must not decrease font size, but must use negative kerning and perhaps some artificial narrowing. How can I do that with ConTeXt? I use MkIV, so any Lua solution is welcome. Greetlings from Lake Constance! Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)

Thank you - but this is fixed narrowing. I also found stretching to a fixed width using \stretched: \hbox to 3.9cm{\stretched{Täxt wÿth ſpöciäl çhaŕàćťërs}} (You don’t need to escape Unicode chars anymore, in contrast to the docs/source.) But what I really need is some width checking like "if this line is wider than 4cm, then use stretching/narrowing". I don’t want to murder typography if the text is short enough.

Hi, I want to measure and typeset the lower case alphabet length. The LaTeX method doesn't work: \newlength{\alphabetlength} \settowidth{\alphabetlength}{abcdefghijklmnopqrstuvwxyz} \the\alphabetlength ConTeXt gives me an error saying that \newlength{...} is undefined. Is it undefined because ConTeXt is built around TeX and not LaTeX and \newlength is a LaTeX command (I do not know if it actually is)? How can I do the same thing in ConTeXt? Regards Christoph

Hi,
I want to measure and typeset the lower case alphabet length. The LaTeX method doesn't work:
\newlength{\alphabetlength} \settowidth{\alphabetlength}{abcdefghijklmnopqrstuvwxyz} \the\alphabetlength
ConTeXt gives me an error saying that \newlength{...} is undefined. Is it undefined because ConTeXt is built around TeX and not LaTeX and \newlength is a LaTeX command (I do not know if it actually is)? yes
How can I do the same thing in ConTeXt? plain TeX is ok, for example, \newdimen\AlphaBet \bgroup \setbox10=\hbox{abcdefghijklmnopqrstuvwxyz} \global\AlphaBet=\wd10\egroup \the\AlphaBet
Use CamelCase to avoid conflits with ConTeXt names. There are much more at http://wiki.contextgarden.net/Category:ConTeXt_programming -- luigi

Thanks to both of you, all three suggestions work. However, I don't understand all of the code. What does \dowithnextbox do exactly? In your last example, does it define the command \measure just for the next box? And why does my email client display this thread as a reply to the "fit to width by negative letterspacing or narrowing" thread started by Henning?

You used the Reply-To function of your mail client (Thunderbird) instead of creating a new message (by for example clicking on the email address of the ConTeXt list).

It’s a high level version of Luigis example. The content of the box with the text “abc…” is saved in the box nextbox which can be accessed with \flushnextbox, the dimensions of the box are available through the command \nextboxht, \nextboxdp and \nextboxwd.
In your last example, does it define the command \measure just for the next box?
\definemeasure is a alternative to dimension and use a macro to store a length. The first argument is the name of the length and you can access the value with the command \measure{<name>} but i forgot to expand the value of the box in my example and it should be: \dowithnextbox {\expanded{\definemeasure[alphabetlength][\the\nextboxwd]}}% \hbox{abcdefghijklmnopqrstuvwxyz} Wolfgang

Ok, I'll add it. There will also be an expandable variant (proper typeset but the string must be utf characters only) \starttext \setwidthof{Robin Kirkham}\to\whatever \whatever=\widthofstring{Robin Kirkham} \stoptext ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
