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

Hello, basically my question is to know if there is a way to use ConTeXt to perform the functions that pdfcrop does. pdfcrop: A Perl script that can either trim pages of any whitespace border, or trim them of a fixed border

(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

Margins using 2UP imposition schema
by Angel M Alganza 16 Sep '24

16 Sep '24

Hello: I'm composing an A5 booklet printed on an A4 paper using the 2UP imposition schema. I believe, in such case, margins should be controlled using 'backspace' and 'cutspace' options of the \setuplayout command, but I'm afraid I don't quite understand how to use those properl. I want to make the 'external' margin (right on odd pages and left on even pages) as small as possible, and the 'internal' margin larger, so that I can hole punch the booklet. I believe, in such case, margins should be controlled using 'backspace' and 'cutspace' options of the \setuplayout command, but I'm afraid I don't quite understand how to use those properly. Here's a minimal example: \setuppapersize[A5][A4] \setuparranging[2UP,rotated] \setuplayout [topspace=13pt, backspace=30pt, cutspace=-20pt, width=fit, height=fit, header=0pt, footer=0pt] \setuppagenumbering[state=stop] \setupbodyfont[small] \starttext \dorecurse{20}{\input tufte \vskip 1em} \stoptext I wonder how I could reduce the left margin and increase the left one on the even pages. Any pointers, please? Thank you so much in advance. Ángel

button
by Hans van der Meer 16 Sep '24

16 Sep '24

\button is defined to jump to a given reference. However, I would like to place a button that can execute a macro to be defined by myself. Thus for example pushing the button \executebutton{text}{macro} will execute that macro. Is this available somewhere in ConTeXT? If not, can it be provided in a future update? yours sincerely dr.

Interline spacing in tabulate paragraphs

15 Sep '24

Greetings, Is there a way to set interline spacing in tabulate environments? The table's paragraphs do not seem to obey \setupinterlinespace like the rest of the text does. Code to toy with: \startdocument \setupinterlinespace[big] \input lorem \starttabulate[|k0r|k0xp|][EQ={---}] \NC Word \EQ definition; \NC\AR \NC Important word \EQ \input dijkstra \NC\AR \NC Importanter word \EQ not much else here. \NC\AR \stoptabulate \stopdocument

Unexpected behaviour of apa-bibliography
by M U 14 Sep '24

14 Sep '24

I do not know anything about the apa-standard, so I do not know if my rendering follows the standard. The first appearance of the author in the bibliography is marked with year-b (1847b), the second with year-a (1847a). I expected the first to be marked with year-a and the second with year-b. Citing multiple references in one \cite[] only 2 out of 3 righttexts appear. When using \setupbtx[apa:cite][sorttype=none] all 3 righttexts appear but the characters after the year disappear. Is there a way to fix that behaviour? Thank you. Have a nice weekend.
