Table and rotation: push together 45 degree rotated cells
by Gerion Entrup 19 Sep '24

19 Sep '24

Hi, I want to typeset a table where some of the column headings are really long, while in the columns itself consists only of numbers. Therefore, my idea was to rotate the column headings but not 90 degrees (I found some solutions for that) but 45 degree. It then would be beneficial to push together the rotated cells, so the text of one cell actually starts above the previous cell. Do you know, how to achieve that? Here is a minimal example: ``` \startsetups[table:rotated] \setupTABLE[frame=off] \setupTABLE[row][first][bottomframe=on, style=bf, align={center, low}] \setupTABLE[row][2][align=flushright] \stopsetups \starttext \define\tablerotate{\dontleavehmode\rotate[rotation=-45, location=high]} \bTABLE[setups=table:rotated] \bTR \bTD \eTD \bTD \tablerotate{Water buffalo} \eTD \bTD \tablerotate{Mexican redknee tarantula} \eTD \bTD \tablerotate{European turtle dove} \eTD \eTR \bTR \bTD Amount of legs \eTD \bTD \digits{4} \eTD \bTD \digits{8} \eTD \bTD \digits{2} \eTD \eTR \eTABLE \stoptext ``` I would like to achieve that the text "Mexican redknee tarantula" is typeset right and above of "Water buffalo" so that the single columns have a width that is similar to the width of the single digit coming in the second row. Another question in this context: Is is possible to specify a \setupTABLE command that works for column 2-4 starting from row 2? Something like \setupTABLE[row][2-][column][2,3,4][background=color, backgroundcolor=red]. In this example this would cover all numbers but nothing else. Best Gerion

Hi, I uploaded a new version. Apart from some things discussed here already the main update is in par passes (a bit more control, feedback, tracing etc) which will be explained over time (we're writing a wrapup).

Inline equations and html export
by Florent Michel 18 Sep '24

18 Sep '24

Hello, Thanks Hans and everyone who has worked on it for the new upload! I have noticed a change which seems to break XML/html export for inline equations; although I don't know if the issue is with the new version or with how I'm using it. Minimal example: ``` \setupbackend[export=yes] \setupexport[alternative=html] \starttext $1 + 1 = 2$ \stoptext ``` When compiling with ConTeXt 2024.09.17 and opening either the `.html` or `.xhtml` file with Firefox or Chromium, the positions of the 2 and = sign are reversed, while the equation is correctly rendered when using ConTeXt 2024.08.16. The (I think) relevant part of the html code generated by ConTeXt 2024.09.17: ``` <div> <math data-lmtx-blob="1" display="inline" displaystyle="false" xmlns=" http://www.w3.org/1998/Math/MathML"><mrow><mn>1</mn><mo mathcharacter="43" mathclass="binary" mathgroup="everygroup" mathindex="43">+</mo><mn>12</mn></mrow></math>=</div> ``` Code generated by ConTeXt 2024.08.16: ``` <div> <math data-lmtx-blob="1" data-lmtx-meaning="1 plus 1 equals 2" display="inline" displaystyle="false" xmlns=" http://www.w3.org/1998/Math/MathML "><mrow><mn>1</mn><mo>+</mo><mn>1</mn><mo>=</mo><mn>2</mn></mrow></math></div> ``` Am I doing something wrong here, or is html export for inline equations not currently supported? Best regards, Florent

any way to show downloading progress for the `install.sh`?
by hf＠hongfeng.ch 18 Sep '24

18 Sep '24

for the installation of ConTeXt, when the shell script `install.sh` start to run, any way to show the downloading progress when it fetches the zip from the site? For example: ``` mtx-install | fetching 'http://lmtx.pragma-ade.com/install-lmtx//texmf.zip' ``` It looks stopped while the downloading is going on. but the user may wrongly regard something goes wrong When the networking speed is slow. Two options would be nice: a) just how the current percentage of the downloaded data; b) even better, under the line, starting a new line, starting with a percentage, then followed by dash characters plus an arrow like `->` to show the downloading progress dynamically --- while the downloaded data adding up, the number of dash characters prolongs accordingly.

(ConTeXt LMTX 2.11.05) how do I make it so that sections, descriptions, and itemizations have just a space between some of the text that they produce
by Felix 16 Sep '24

16 Sep '24

\setuppapersize[letter][letter] \setupalign[normal] \setuplayout[ backspace=0.5in, topspace=0.0in, header=.5in, % No headers footer=.5in, % Space for the footer width=middle, height=middle, ] \definefontfeature[timesfeatures][default][ trep=yes, % Enables single and double quotes to show up correctly in text, perhaps does more dlig=yes, % cpsp=yes, use for all caps only ] \definefontfamily [myfonts] [rm] [Times New Roman] [features=timesfeatures] % dlig enables times new roman ligatures, and cpsp is used by tnr, not aptos \setupbodyfont[myfonts,12pt] \mainlanguage[en-us] \setupindenting[yes,0.5in] \definedescription[description] \setupdescription[description][ alternative=serried, headstyle=bold, style=normal, width=broad, before=, after=, ] \setupheads[indentnext=yes] % To get indentation after section numbers, use this \setuphead[section][ sectionstopper={.}, % Add period after numbers conversion=R, before=, after=, style=sc, % Small caps style align=middle, % Center the section titles ] \startsetups document:start \centerline{\documentvariable{title}} \centerline{\documentvariable{author}} \centerline{\documentvariable{date}} \blank[line] \stopsetups \startdocument[ title={Chapter 4 Quiz}, author={Author}, date={September 16, 2024} ] \startitemgroup[itemize][n] \startitem I'm not a fan of the default spacing \stopitem \stopitemgroup \startdescription{I'm not a fan of the} default spacing \stopdescription \startsection[title={I'm not a fan of the}] default spacing \stopsection \stopdocument This code shows how I am getting the default spacing between the words from itemize, description, and the spacing between the roman numeral and the section title. I tried figuring out how to get the spacing for all of these to be set to a single space worth but it seems to not be possible with `distance`, because it asks for a dimension. How can I get a `\space`'s worth of spacing to be the default in descriptions, itemizations, and sections? for itemizations and descriptions the spacing seems to vary and I really don't like that. I would be thankful to know if there's a way to change the spacing.

Calling C code from ConTeXt LMTX
by Florent Michel 16 Sep '24

16 Sep '24

Hello, TL;DR: Could building LuaMetaTeX with the `-fPIC` flag for the Lua library have negative consequences? Is there a better way to be able to call external C functions from ConTeXt? I am working on a small project where it would be convenient to call functions written in C (possibly pre-compiled in a shared library) from ConTeXt. After looking at the Lua FFI, I found a way that seems to work (with ConTeXt LMTX 2024-08-16) but requires a small tweak to the cmake file used for building the Lua library. I would be grateful to have the opinion of people more knowledgeable than I am about whether this change could have negative consequences and whether there is a more straightforward way to call external C code. What I am trying to achieve is: * Compile some C code in a shared library (for instance, it may contain a numerical solver for some partial differential equation). * Have this code run when compiling a document with ConTeXt. (For instance, solving the differential equation with parameters defined in the .tex file and retrieving the results to plot a figure with MetaPost.) One easy way to do that is: * Write wrappers for the functions that will need to be called from ConTeXt using the Lua C API. * Compile the code and wrappers in a shared library and linking to the static lua library used by LuaMetaTeX (liblua.a on Linux). * In the .tex file, import the new library using, e.g., ``` \startluacode mylib = require("mylib") -- additional code using the C functions \stopluacode ``` * Run ConTeXt with the `--permitloadlib` flag. However, the second step requires (at least on Linux) liblua.a to be compiled with the `-fPIC` flag. I could do that by adding ``` set_property(TARGET lua PROPERTY POSITION_INDEPENDENT_CODE ON) ``` at line 47 in lua.cmake. Is there any known negative effect of doing that (apart from a possible small performance drop)? (Just to be clear, this is not a feature request; I'm just wondering whether doing it on my side is fine.) On a related note, is there a standard way to call external C functions (either in a shared library or in a .c file) from ConTeXt LMTX? The SwigLib library described in https://www.pragma-ade.nl/general/manuals/swiglib-mkiv.pdf looks very promising (and maybe could be a way to achieve what I'm trying to do in a much cleaner way), but I (maybe for lack of trying hard enough) have not been able to make it work with ConTeXt LMTX so far. Best regards, Florent
