The last line

The last line

[Steffen Wolfrum]

Hi,

as far as I know TeX has some internal rules (and penalties) for judging where to hyphenate words or not in order to keep a paragraph not too densed and not too loose. Some rules can be modified by commands like tolerance, spaceskip, emergencystretch et al.

Now, I want to have control over the last line. I would like to avoid syllables smaller than (for example) 4 letters being the only element in a paragraphs last line. Like this:

xxxx xx xxxxx xxxx
xx xxx xxxxxxx xx-
xxx.


Is there a way to make a kind of global definition for this for the entire document?


Thanks for any hints,

Steffen

and alike, however, i recently added s bit more clever support for this, using setups and etex features; consider setups to be a kind of macro, not sensitive for funny spaces; system setups are those starting with a *  

\startsetups [*reset]
  \resetpenalties\widowpenalties
  \resetpenalties\clubpenalties
  \resetpenalties\interlinepenalties
\stopsetups

\startsetups [*default]

  \setups[*reset]

  \widowpenalty\defaultwidowpenalty
  \clubpenalty \defaultclubpenalty

\stopsetups

\startsetups [grid] [*default]

  \setups[*reset]

  \widowpenalty\defaultgridwidowpenalty
  \clubpenalty \defaultgridclubpenalty

\stopsetups

These are bound to the setuplayout command, 

In addition you can define your own:  

\startsetups [i-like-them-this-way]

   \setups[reset]

   \setpenalties\widowpenalties2{10000}
   \setpenalties\clubpenalties 2{10000}
                \brokenpenalty  {10000}

\stopsetups

\setuplayout[setups=i-like-them-this-way]

use those high values with care; 10000 is pretty high and a special number for tex and the scale is not lineair. If you want horrible results, try:

\startsetups [only-if-we-are-forced-to]

  \displaywidowpenalty 10000
  \widowpenalty        10000
  \clubpenalty         10000
  \brokenpenalty       10000
  \doublehyphendemerits10000 
  \finalhyphendemerits 10000 
  \adjdemerits          5000 

\stopsetups

Esp with left/hyphenminvalues >=5 this will lead to rather bad paragraphs but we've run into designers who love this.  

(slowly a lot of internals will be defined this way, along with some fundamental redefinitions of other internals, consider it a kind of ConTeXt4 feature-)

There are a few TeX primitive commands that govern the final line of a paragraph:

	\finalhyphendemerits=\maxdimen % disables hyphenation of final line
	\parfillskip= 0pt plus .8\hsize % disallow final lines shorter than 20% of \hsize

ConTeXT might alter the values of these primitives occasionally (unlikely but I am not 
certain) so maybe you have to repeat these settings a few times.

that means \placefigure{top,left}, WITH text around it, won't be doable in ConTeXt?
not even in your idea of ConTeXt4?

hm, graphic placement is and will always be tricky 

btw, \placefigure[outer]{}{} does work (see details.pdf)

as long as top/left i snot something with text aroun dit, it's doable -)

Maybe something like 

\placefigure{top,left} 

or 

\placefigure{bottom,outer}

could be another ConTeXt4 feature? -)
