I've seen some discussion about creating a verse environment in ConTeXt that handles the alignment of long (broken) lines of text. But I can't find anything about optical centering as can be done in LaTeX using the gmverse package: http://www.ctan.org/pkg/gmverse

Is there something like this available for ConTeXt?

Can you make a PDF where we can see what do you want?

The documentation for the gmverse package probably explains it better than I can. Here's a direct link: http://mirror.ctan.org/macros/latex/contrib/gmverse/gmverse.pdf

That's just a bunch of macro code ... what Wolfgang meant was output that you want to see. Writing from scratch fo rwhat you need is easier that deciphering macro code.

My apologies, this is what I meant to link to, a TUGboat article which has both the formulae for calculating the center and visual illustrations of the resulting centering: www.tug.org/TUGboat/tb29-1/tb91murzynowski-text.pdf

The package provides three things, in descending order of importance for me:

* optical centering, which is a calculation of the center point for the alignment of the box of text that is based on based on an average of the line lengths of the work being set. gmverse provides four different possible centering methods based on different formulae (if it matters, method 3 and 2 are most useful.

Centered text based on the longest line is simple but when it’s better to make this a feature of the lines environment. \def\startverse {\begingroup \dostartbuffer[versecontent][startverse][stopverse]} \def\stopverse {\setbox\scratchbox\hbox\bgroup\framed[width=fit,align=right]\bgroup \startlines \getbuffer[versecontent] \stoplines \egroup\egroup \leftskip\the\dimexpr(\textwidth-\wd\scratchbox)/2\relax \startlines \getbuffer[versecontent] \stoplines \endgroup} \starttext \showframe \startverse ASM rządzi dioda świeci miodowo chrząszcz chrzęści w czcionkach. \stopverse \stoptext

* Alignment of broken lines, right-aligned to the length of the line above the break

I guess Hans can do this when he provides a setting similar to “align=last”.

* An environment that needs no use of \\ to break lines, but does so based on the length of the line and automatically wraps long lines (as defined by a dimension) and uses the alignment above.

This is more or less what the lines environment does. \startlines line 1 line 2 … \stoplines Wolfgang

Yeah, but it *isn't* based on the longest line, but on an average of line length. I guess that's why it is call...well, except for the first example in the doc provided, which is what I think your code does.

Though the code you provided is very useful, so thanks!

I showed only it’s not so hard to achieve this feature but with a more complex solution where you check the width of each line you can use different values for the margins. Wolfgang
