rotated headers in natural tables
by Henning Hraban Ramm 20 Mar '23

20 Mar '23

Hi! In my table, I want the header texts to be 90˚ rotated and aligned to the bottom of their cell. I couldn’t find an option to do that. Tried \dontleavehmode or \hfill in my \RtH macro to no avail. Is it possible? \define[1]{\RtH}{\rotate{#1}} \starttext \setupTABLE[offset=3pt] \setupTABLE[header][background=color,backgroundcolor=yellow,align=bottom] \bTABLE \bTABLEhead \bTR \bTH\RtH{animal}\eTH \bTH\RtH{size}\eTH \bTH\RtH{weight}\eTH \bTH\RtH{average speed}\eTH \eTR \eTABLEhead \bTABLEbody \bTR \bTD sparrow \eTD \bTD small \eTD \bTD light \eTD \bTD high \eTD \eTR \bTR \bTD dog \eTD \bTD medium \eTD \bTD medium \eTD \bTD medium \eTD \eTR \bTR \bTD snail \eTD \bTD small \eTD \bTD light \eTD \bTD slow \eTD \eTR \bTR \bTD elephant \eTD \bTD big \eTD \bTD heavy \eTD \bTD medium \eTD \eTR \eTABLEbody \eTABLE \stoptext Hraban

update
by Hans Hagen 20 Mar '23

20 Mar '23

Hi, I updated LMTX. Most improvements are in 'math' as Mikael and I keep mailing down some details that bother us. We also have some updates in the math fonts that Daniel Flipo maintains so the repertoire of alternatives with all-right math support grows. As a side note: lmtx installs nicely on my android (12) phone (userland ubuntu) and luametatex compiles nicely from source (as it's aarch64) in about a minute. No decent editor to text real documents but who knows what a properly dockable (linux supporting) phone can do in a few years. A simple \starttext \dorecurse{1000}{\samplefile{tufte}\par} \stoptext runs at over 55 pps (85 pps on my laptop). Making a format takes 4 seconds (second time, after caching, which is about twice the time my laptop takes).

Printing problem
by Mikael Sundqvist 20 Mar '23

20 Mar '23

Hi all, I have had some printing problems lately, and it is not perfectly clear to me (or to Hans, we have discussed this a bit) whether it is the printer that has a lack of memory or if the pdf files are somehow corrupted. It might have to do with type3 fonts. I attach a pdf file that does not print on our printer at work. Or well, it prints almost all of the page, but stops at the word "negativa" (or was it "egenvärden", I do not have the printout here right now). Then the printer also prints an error report about some "offending command". So, a request: If you have an easy access to a printer, can you print this page and report back if all of it comes out, or what is happening? Thanks /Mikael

Absolute positioning of \startcombination... \stopcombination
by Keith McKay 17 Mar '23

17 Mar '23

Hi, I would like to position a combination of images where the centre of the combination coincides with the centre of the text area of a page. In the example below I have made the combination into a layer thinking that this would be the easiest way to position it where I wanted. However to position in the centre of the page I would need to know the size of the combination and use this to calculate the x and y values for positioning of the layer. I have looked at the Wiki page on image size of combinations but still cant figure out how to do it. Any suggestions on how to go about this or is their a better way? Wiki Page reference: https://wiki.contextgarden.net/Combinations#Image_Width Thanks Keith McKay %%% example %%% \setuppapersize[A4,portrait]%[A4,portrait] \setuplayout [backspace=2.5cm, topspace=1cm, height=28cm, width=17cm, header=0cm, footer=0.75cm, ] \useMPlibrary [dum] \starttext \definelayer[test3] \setlayer[test3][x=2cm,y=15cm] {\startcombination[nx=3,ny=1,distance=15mm,after=,location=middle] {\externalfigure[dummy]}{} \rotate[rotation=90]{\externalfigure[dummy]}{} {\externalfigure[dummy][]}{} \stopcombination} \flushlayer[test3] \stoptext

Undefined control sequence error message
by Leah Neukirchen 16 Mar '23

16 Mar '23

Hi, LMTX prints a bit weird error message for undefined control sequences: \starttext \zong \stoptext tex error > tex error on line 2 in file ./foo.tex: Undefined control sequence \undefined <line 3.2> \zong Shouldn't it print "\zong" in the "tex error" line too? -- Leah Neukirchen <leah(a)vuxu.org> https://leahneukirchen.org/

Automatic numbering of footnotes set with \note (not with \footnote)
by Joaquín Ataz López 16 Mar '23

16 Mar '23

Good Morning to all list members. I am writing a document with very long footnotes, and in order not to break (in the source file) the flow of the main text, instead of using the \footnote macro, I introduce the footnotes using \note[label] at the point where the call to the footnote should be placed, and in a separate place in the source file I write the text associated to the footnote using \footnotetext[label]. This works quite well and allows to create a more readable source file. There is, nevertheless, a small inconvenience, and it is that when processing the document ConTeXt goes numbering automatically the notes, attending to the order in which they are, in the source file, the \footnotetext commands. Would there be a simple way so that the automatic numbering follows the order of the \note commands, and not that of \footnotetext? Maybe something with \startbuffer combined with a counter? -- Joaquín Ataz López Departamento de Derecho civil Universidad de Murcia

Bug in columns
by Li Yanrui (李延瑞) 15 Mar '23

15 Mar '23

Hi, There are some footnotes in my text. When I use \startcolumns...\stopcolumns, the locations of footnotes are not right. Please see the followging sample: \starttext If there is a footnote here\footnote{It's a footnote!}. \startcolumns[n=2] \input knuth \column \input knuth \stopcolumns The result is not right. \stoptext The result is attached. My lmtx version is 2023.03.10 12:18. foo.pdf <https://drive.google.com/file/d/1zSUTCVsssoET9Pr88f8VIzQGdMnnzpjg/view?usp=…> -- Best regards, Li Yanrui

How to extend an existing macro to take optional parameters?
by Bruce Horrocks 14 Mar '23

14 Mar '23

I have an existing macro that I'd like to extend. The current definition is \define[3]\mycommand{...} which I'd like to extend to take an optional 4th parameter plus an optional setup parameter. Thus I currently invoke it as: \mycommand{aa}{bb}{cc} and I'd like to be able to extend it so that any of the following can be used: \mycommand{aa}{bb}{cc} \mycommand{aa}{bb}{cc}{dd} \mycommand{aa}{bb}{cc}{dd}[ee] or \mycommand[ee]{aa}{bb}{cc}{dd} % if this is more the ConTeXt way where {dd} is the optional extra parameter and, if it is present, then [ee] can also be optionally added (because it controls how {dd} is printed). If it helps, the actual body of the macro can easily be a call to Lua so it's fine if the function takes 5 params where 4 and 5 can be nil or empty strings. I've trawled through syst-aux.mkiv but it only covers optional numbers of [ ] or { } but not combinations of both (which given the vast numbers of combinations is perhaps not surprising!). Have I missed something obvious that would help me? Regards, — Bruce Horrocks Hampshire, UK
