sorry, but this is not what is needed (see attached pdf, please) this tight interlinespace is not possible in MkIV when grid mode is on? Steffen

well, you want things on a grid ... if you don't want that don't use grid mode or snap a box on the grid and disable gridmode inside the box alternatively you can define a grid instance where spacing is handled differently, \setuplayout[grid=none] you can define variants with different thresholds (for ht and dp), extra lines, etc Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

I just made a test: even without grid mode the "\lineskiplimit-\maxdimen" doesn't work in MkIV as expected. Please run the example below: it will not show 10pt interlinespace. \usetypescript[postscript] \definetypeface[postscript][rm][serif][times][default] \setupbodyfont[postscript,30pt]\setupinterlinespace[line=10pt]\lineskiplimit-\maxdimen \starttext \input tufte \par \stoptext Steffen (ConTeXt ver: 2010.08.04 13:11 MKIV)

Sure, these minimal examples somehow look silly. But this is only because I try to make the problem clear in a minimal file. In real life it is more serious and there it is nothing weird at all. Using "\lineskiplimit-\maxdimen" is more like a life insurance: Given, you have a predefined interlinespace (eg. the publishing house told you). And, for several reasons you want/need to use grid mode. Everything is set up fine and works nicely ... until on one page, there is a "g" and below is "É" (like in Étude). Suddenly these two lines seem to have a bigger interline space! You didn't expect this french word is used in your project. But the printer inspected the galley proofs and saw it. That's really an awkward situation ... And that's why I need this functionality in MkIV, too. Steffen

this is because \starttext synchronizes a couple of settings, so you have to set the limit just before you need it (and then probably have to use it grouped and end the par in the group) there are more primitive settings that sync regularly so don't depend on them being set persistent if you change their value Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

alternatively you can define a grid instance where spacing is handled differently,
\setuplayout[grid=none]
you can define variants with different thresholds (for ht and dp), extra lines, etc
Could you give an example on this (thresholds for ht and dp), please? Indeed, the new options with grid mode are enormous. I just tried "local" and the result looks as desired. I only can't estimate what side-effects it might have in a real-life-project. What does "local" do here, as there are only global settings?! \usetypescript[postscript] \definetypeface[postscript][rm][serif][times][default] \setupbodyfont[postscript,30pt]\setupinterlinespace[line=10pt] \setuplayout[grid=local] \starttext \input tufte \par \stoptext Best, Steffen

This I know, only I don't understand the syntax ;o) Is this "0.8" the threshold you mentioned ... \definegridsnapping[\v!strict] [\v!maxdepth:0.8,\v!maxheight:0.8,\v!strut] or "0.8" in here ... \definegridsnapping[\v!broad] [\v!maxheight,\v!maxdepth,\v!strut,0.8] Or is the second kind of abbreviation for the first?

indeed in mkii we had all kind of keywords, here we have sets that provide more control
And even more interesting: what does "local" do, I mean really? "% local use local interline space"
Do I have local interline space in my example?
normally grids will obey the global settings, local settings can be handy when building boxes with different spacing that then are snapped globally as a whole (section heads already have a grid key for local settings and more constructs will have them0 ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
