[...] Everthing is fine when italic fonts aren’t used.

It can be fixed with a strut option for lists, e.g. \setuplist[strut=no]. The problem in this case is that the ex-height for the italic font is larger than the ex-height for the upright font which pushes the text down because add a strut at the begin and end of the entries.

Many thanks for your reply, Wolfgang. I don’t get \setuplist[strut=no] working in the minimal sample I sent yesterday.

Below is a minimal example of the problem, the \setstrut setting changes the height of the strut for the italic font.

I must admit that I don’t understand how to handle struts (I’m not sure I understand what they actually are.)

Most fonts (I checked only a small number) don't have such a big difference between the ex-height of the upright and italic styles which makes it hard to notice the problem.

Yesterday I realized that Pagella was an extreme case, because I tried to report this issue before, but Latin Modern didn’t show the issue (so I thought I was doing something wrong). Many thanks for your help, Pablo -- http://www.ousia.tk

The key isn't supported yet but it could help to avoid the spacing problem.

The simple answer is that a strut is a invisible vertical line with the height and depth of a line. When you look at the example below you can see the text in the first box touches the top and bottom boundaries.

When we add a strut at the begin and end of the text we ensure the last line has the depth of a normal line and the first line gets the complete height of a line.

%%%% begin example \starttext

\ruledvbox{\samplefile{weisman}}

\blank

\ruledvbox{\begstrut\samplefile{weisman}\endstrut}

\stoptext %%%% end example

Yes, pagella is a extreme case but when you use bold text the vertical spacing is also messed up. You can avoid this when you use a fixed lineheight (e.g. \setupinterlinespace[line=14pt]) because the default distance is font dependant (default: 2.8 * ex-height). or one can play with these parameters, that default to:

\setupinterlinespace [height=.72, depth=.28] (maybe we should have recomended values for specific fonts) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

I had similar problems in the past and got to 2.9ex for Alegreya 3.2ex for Adobe Jenson

(Just tried, didn’t calculate anything.)

How would this help for the original problem? Wolfgang

How would this help for the original problem? Some fonts have a different ratio (I forgot what font i did .7 / .3) but indeed an all-bold or whatever style change sometimes demands a local \setupinterlinespace (no argument).

I know there are cases where changing the height/depth ration can help but in this case the problem is caused by \strut which is bigger for the italic font. A way to fix the wrong spacing here is to add a strut option to \setuplist (or use always the upright font to set the strut values).

Of course one could also tweak the ht/dp of a specific style using one of the pseudo features.

Also possible because the larger value for the ex-height of the italic font causes the bigger strut dimensions. Wolfgang
