Kerning

Kerning

[Bart C. Wise]

I am trying to change the spacing of a chapter title head.  I found the 
"\kern" command; however, I could not get that to work over a string of text.

Then I found the following code:
\def\dolist{\afterassignment\dodolist\let\next= }
\def\dodolist{\ifx\next\endlist \let\next\relax
   \else \\\let\next\dolist \fi
   \next}
\def\endlist{\endlist}
\def\track#1\by#2{\def\\{\next\kern#2}%
   \leavevmode \hbox{\expandafter\dolist#1\endlist}}

Then I tried:

def\MyChapterCommand#1#2{
        \framed[align=center,frame=off,width=\textwidth]{
		\vbox{
			\track{This is a Test} \by{.2em}
			\track #2  \by{.2em}
		}
	}
\setuphead[chapter][
    command=\MyChapterCommand
}

The output from the \track{This is a Test} \by{.2em} works.  However, the 
second track command (\track #2 \by{0.2em}) fails.

I spent many hours last night trying to change the kerning.  What I want is 
something like: \kern{TEXT}{KERNING AMOUNT}.  

What's available, or how do I fix the track command above.  By the way,I'm 
running mkii.

Thanks,
Bart

Search for \stretched and \stretchednormalcase.

Re: Kerning

Okay, it works until I place an an argument in the stretched command.

def\MyChapterCommand#1#2{
       \framed[align=center,frame=off,width=\textwidth]{
		\vbox{
fails-->			\stretched{#2}
works-->			\stretched{This is a Test}
		}
	}
\setuphead[chapter][
   command=\MyChapterCommand
}


I get the following error when I run texexec:

! Missing \endcsname inserted.
<to be read again>
                   \let
\nextprocessedtoken ...oup \ifincolor \ifcsname #1
                                                  #3\endcsname \let 
\dostopa...

\dodoprocesstokens ...token \let \before \between
                                                  \fi \let \nextprocessedtok...
<argument> This is a test: \dostartattributes
                                              {\??ko \v!title }\c!style 
\c!c...

\processtokens ...fore \before \doprocesstokens #5
                                                  \lastcharacter \endgroup
\stretched ... \relax \hss \relax {\hss \hss }{#1}
                                                  \egroup
...

How can I use the #1 & #2 arguments in the stretched command?

You could use it only with \deeptextcommand, here is a old mail
with a example from Hans (you could ignore the other code).

Re: Kerning

[Bart C. Wise]

Wolfgang,  thanks so much for your help so far.

I was able to take the code and make it work correctly to stretch the chapter 
title.  What I want is two lines for a chapter head.  For example,
Line 1: "Chapter One"
Line 2: "Title for Chap 1"

I want line 1 to be stretched.  Everything I have tried does not work.  I can 
get the "Chapter" word to stretch, but not the whole line (and it should 
probably be treated as a whole line when stretching).  I was never able to get 
the chapter number (now a word) to stretch.

So how do I grab the output for line 1 and then stretch it?

Here's a sample of what I have without any stretching:

\def\Myheader#1#2{%
    \framedtext[width=0.60\textwidth, frame=off, align=middle]{%
        \vbox{\headtext{chapter}~#1 \blank #2}}}

\def\englishnumbers#1{
    \ifcase#1 \or ONE\or TWO\or THREE\or FOUR\or FIVE\fi}
\defineconversion[englishnumbers][\englishnumbers]

\setupsection[chapter][conversion=englishnumbers]
\setuphead [chapter][
    command=\Myheader,
    textcommand=\bfd,
]
\setupheadtext[chapter=CHAPTER] % used by \headtext
\starttext
\chapter{Title for Chap 1}
\processfile{tufte}
\stoptext


P.S. If there's a better way to do the number->word conversion, let me know.

look for the property mechanism

\startproperty[stretch]stretched\stopproperty

token processing is always tricky since the parser does not know what to 
expect; properties use a pdf trick; in mkiv we have more clever stretching

Hans,

I tried the above code and it failed.  I looked around on the ConTeXt site and 
the web in general.  It seems like a \defineproperty[stretch] needs to be 
declared, but I can't find it anywhere.  You'll have to excuse my ignorance, 
but will you be explicit on how to use the \startproperty[stretch] stretch 
\stopproperty.

hm, something is missing in the mkii file

\unprotect \definepropertyhandler \v!stretch{0} \protect

(you can also tune the 'normal effect')

consider all this a hack, since tex does not know about the right 
dimensions

in mkiv there's

\start \dosetstretch{.25em} \setuptolerance[tolerant,stretch] \input 
tufte \endgraf \stop
\start \dosetstretch{.5em} effe flink doorfietsen \stop

(not yet interfaced but it should work)
