I was rerunning ConTeXt on some older documents and the interline space isn't the same. Sure, the new default looks great, but what was the old default? I need to match what I've already published. Thank you♥ Sandra

Hi Sandra, which version did you use to generate those documents? I mean, \setupinterlinespace defaults are defined in spac-def.mkiv (for MkIV), which read in the latest beta: \setupinterlinespace [\c!minheight=0pt, % only special purpose \c!mindepth=0pt, % only special purpose \c!height=.72, \c!depth=.28, \c!top=1.0, \c!bottom=0.4, \c!distance=1pt, \c!line=2.8ex, \c!stretch=0] In MkII, the definition seems to be basically the same in latest beta. There is a GitHub repo at https://github.com/contextgarden/context-mirror/. Older defaults could be checked there. BTW, I thought that the default was "\setupinterlinespace[line=2.85ex]". But it seems that it is 2.8ex since at least 2013 (http://pmrb.free.fr/contextref.pdf#page=113). It might be that default values for interline space haven’t been modified in ConTeXt for a long while. Just in case it helps, Pablo -- http://www.ousia.tk

Thank you♥ The interlinespace is defined in 'ex' units so it depends on that value in the font that you use ... maybe the font changed?

That's certainly possible. I switched computers and distros so all of those things might've been refreshed or altered upstream. I'm using Junicode for the main & bold but with Tex Gyre Schola for italic, and then grabbing miscellaneoussymbols out of a DejaVu Serif fallback and using DejaVu Sans Mono for mono (althought this particular page doesn't have any mono). If it isn't that case that those fonts have changed their metrics, which I wouldn't know, I'm kinda out of the loop generally (#unplugged), I was thinking that maybe the culprit could be that it used to work off of the italic's ex height and now works off of the main's ex height but that's just wild guessing on my part. I'm working around the problem by setting the interline space to 3.0675ex which makes the recompiled pages match the previously compiled pages exactly. (I don't know why that number. I found it by trying every number and seeing what matched.) The previously compiled pages didn't have an interline space set. Thanks again. Sandra

if you still have the old installation you can do this someplace in the file: \the\dimex2.8ex % or whatever value you used for interlinespacing and then use the reported value in the updated installation
