placing an MPGraphic/Lines over multiple table cells
by Martin Althoff 05 Jan '19

05 Jan '19

I am trying to place some lines in "Z" shape over several cells of a table. This single "Z" has the intention of blocking manual alterations to the table in empty cells. The cells to blocked are always a coherent rectangle. I hope that makes sense. In the example below, the table with 4 rows, 3 columns has content in column one only, the other 2 columns should have the "Z". Placing the blocking "Z" into every cell is not an option due to formal requirements. What I attempted below a) seems very cumbersome b) doesn't work (the small "Z" doesn't fill the frame). While I can easily place a "Z" into a single cell (in the example), I can't figure out how to cover multiple cells. Furthermore, I would need to do a lot of calculations to figure out the multiple layer placements, column positions, etc. With multiple tables on a page, several pages, that seems error prone. Any suggestions, corrections, hints are most welcome! Kindly, Martin Working example with some comments: % Graphic that draws the "Z", that works fine in a single table cell as seen in the example \startuseMPgraphic{ZRule} rulethickness:= \frameddimension{rulethickness}*3; drawoptions( withpen pencircle scaled rulethickness withcolor \MPcolor{\framedparameter{framecolor}}); pair topleftcorner, toprightcorner; topleftcorner := (rulethickness, \overlayheight-rulethickness-1.5mm); toprightcorner:= (\overlaywidth-rulethickness, \overlayheight-rulethickness-1.5mm); pair lowerleftcorner, lowerrightcorner; lowerleftcorner := (rulethickness, rulethickness+1.5mm); lowerrightcorner:= (\overlaywidth-rulethickness, rulethickness+1.5mm); draw topleftcorner -- toprightcorner; draw lowerleftcorner -- lowerrightcorner; draw toprightcorner -- lowerleftcorner; \stopuseMPgraphic \defineoverlay[ZRule][\useMPgraphic{ZRule}] \starttext \setupTABLE[c][each][width=30mm] \setupTABLE[r][each][width=6mm] % in an attempt to place the table at known positions, I put it into a layer.

Hi there, somehow floats that I place with keywords location=left or location=rightcreate a blank page first. Am I missing anything? I am sure that this wasn't the case before 19.12.2018. Right now I have the recent 03.01.2019 version. My MWE and an image of the output: \starttext \startplacefigure[ title={Caption}, location=left] \externalfigure[logo--context][width=] \stopplacefigure \input tufte \stoptext Greetings, Lars.

I cannot get the general setup macros of itemize right. I suppose I am missing some clues although I tried to follow the Command Reference distributed with the contextbeta. Here my minimal working example. dr. Hans van der Meer

two different outputs.
by Jeong Dal 01 Jan '19

01 Jan '19

Dear all, First, Happy new year! I tried to make a style of title as following. The first code creates the title as I wanted, but the second which uses “\title” creates the title strange. they are almost same code. To include it in the list of contents, I use “\title”. Is there a way to make output as the first one and include it in the list of contents? Thank you for reading.

\quad confusion
by Floris van Manen 27 Dec '18

27 Dec '18

When trying to typeset, luatex kept complaining about incorrect parameters for ‘minus’. There is no \minus command in the source however. So it turns out that the combination of using \quad with ‘plus’, 'minus', and some more make the error appear. If i rewrite minus by {minus} the error does not show up either. \starttext \quad minuskel \stoptext Where do i go wrong? Thanks. Floris
