Adjusting column width dynamically to get rid of orphans and widows
by Thomas Widmann 03 Jul '17

03 Jul '17

Hello, I recently started experimenting with using ConTeXt (mkiv) for dictionary typesetting. It's a much more attractive option than plain TeX or LaTeX because of the support for typesetting on a grid. However, grid typesetting can easily result in a large number of orphans and widows, which really doesn't look good in a dictionary. In an ideal world, I'd want to alter the column width slightly to prevent them (because most dictionaries aren't justified, this wouldn't be very noticeable). Would it be possible to use LuaTeX to achieve this? I.e., could one write some code that gets triggered by orphans and widows and then alters the current column width slightly until the problem disappears? Has somebody already done this? Or have the relevant TeX internals not been Luafied yet? I'd also be interested in other ways to solve this issue – for instance changing the looseness dynamically instead of the column width. Thanks a lot, Thomas -- Thomas Widmann Director Complexli Limited +44 789 444 3009

mathalignment and grid
by Henri Menke 03 Jul '17

03 Jul '17

Dear Hans, In a previous email I complained that with mathalignment large formulas crash into the paragraph below when using grid typesetting. This has been fixed in the latest beta but now the space above and below is asymmetric. For this particular case I could fix it by setting the gird snapping mode to "top" rather than "math", but this does not apply universally. Any chance there is an easy fix? Cheers, Henri --- \setuplayout[grid=both] \showgrid \startmode[fix] \unprotect \def\math_alignment_snap_start {\ifgridsnapping \snaptogrid[top]\vbox\bgroup \fi} \protect \stopmode \starttext \input knuth \startformula \startmathalignment \NC i\hbar\frac{\diff}{\diff t}\psi \NC= \left( - \frac{\hbar^2}{2 m} \nabla^2 + V(r) \right) \psi \NR \NC F(x) \NC= \int f(x) \diff x \NR \stopmathalignment \stopformula \input ward \stoptext

Overarc etc. symbols
by Jaroslav Hajtmar 03 Jul '17

03 Jul '17

Hello ConTeXist. Can someone advise me how to lay an arc over three letters AVB. It's about the LaTeX equivalent of \overarc or \widearc macro. Is there any table of similar ConTeXt symbols? Thanks Jaroslav Hajtmar
