Hi, I pploaded a new lmtx (no rpi 64 bins yet, one can pick these up from the build in a few days). Apart from a few fixes (older side float issue, some recent special rule related things) the only new thing is 'low level anchoring'. More can be found in ontarget.pdf (ontarget-anchoring.tex). It basically boils down to boxes listening to source, target and anchor keys, as in: \vbox source 123 \bgroup \offinterlineskip \blackrule[width=4cm,height=2cm,depth=0cm,color=darkred]\par \blackrule[width=4cm,height=0cm,depth=1cm,color=darkblue]\par \setbox\scratchboxtwo\hbox anchors "0004 "0001 % anchor "00040001 target 123 orientation 1 {\blackrule[width=2cm,height=1cm,depth=0cm,color=darkgreen]% \hskip-2cm \blackrule[width=2cm,height=0cm,depth=1cm,color=darkyellow]}% % \smash{\box\scratchboxtwo}% \egroup the mentioned document describes a bit higher interface (plugs into layers) .. all kind of experimental and meant as teaser for users who like low level stuff (playground). I also made it possible to use context \frules with leaders as in: test \leaders \frule height 6mm depth 3mm radius 1mm\hfill test \startuseMPgraphic{demoleader} fill unitcircle xysized (RuleWidth,RuleHeight+RuleDepth) withcolor RuleColor ; \stopuseMPgraphic test {\red \leaders \frule height 6mm depth 3mm type mp data {\includeMPgraphic{demoleader}} \hfill} test \startuseMPgraphic{demoleader} drawdblarrow (0,RuleHeight) -- (RuleWidth,RuleHeight) withpen pencircle scaled RuleThickness withcolor RuleColor ; \stopuseMPgraphic test {\red \leaders \frule height 1mm % we need at least some dimensions type mp line 1mm data {\includeMPgraphic{demoleader}} \hfill} test (leaders can have boxes, rules and also glyphs) In principle we can also have adaptive images (basically scaling) so I might make an example of that later (when i need it). Of course I'll fix things I broke this time, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Is there a syntax for making many index entry's all in one?
by Joel 28 Dec '21

28 Dec '21

I am using \index{} to populate \placeindex (an index) with items. I am wondering if there is any syntax that allows one \index{} command to define more than one entry, for example, something like this: \index{presidents+Lincoln, Abraham; Lincoln, Abraham} The result is two appearances in the index: LLincoln, Abraham Ppresidents Lincoln, Abraham Is there some syntax for making this possible, without calling \index{} multiple times? --Joel

Strange behavior with \startbodymatter ... \stopbodymatter
by Fabrice Couvreur 28 Dec '21

28 Dec '21

Hi, In my file cours_premiere.tex if I indicate \startbodymatter \component[probabilites.tex] \stopbodymatter I get the following error message tex error > tex error on line 49 in file ./cours_premiere.tex: Undefined control sequence \pgfmath@settrigformat <inserted text> \pgfmath@settrigformat \pgfmath@settrigformat \pgfmath@settrigformat <line 3.49> \stopbodymatter 39 [criterium=all, 40 interaction=all, 41 alternative=c] 42 43 \stoptitle 44 45 \stopfrontmatter 46 47 \startbodymatter 48 \component[probabilites.tex] 49 >> \stopbodymatter 50 51 52 \stopproduct The control sequence at the end of the top line of your error message was never \def'ed. You can just continue as I'll forget about whatever was undefined. mtx-context | fatal error: return code: 1 TeX Output exited abnormally with code 1 at Tue Dec 28 15:31:31 On the other hand, if I indicate \component[probabilites.tex] the file compiles without error. Thanks Fabrice

Contextual removal of some ligatures using fonts.handlers.otf.addfeature (LuaTeX 1.13.2)
by Thomas Savary 27 Dec '21

27 Dec '21

Hello, dear list ! In order to fix a few bugs in some OpenType features included in EB Garamond font provided by Google Fonts, I am trying to remove some ligatures (erroneous in some contexts) with fonts.handlers.otf.addfeature. I must be missing something, because I can't get it to work. Here is a minimal —non working—example :-) (The attempted removal (“f_i” → “fi” only before “o”) is of course irrelevant. I chose it just for the sole purpose of this test, to provide a simple example. What I am trying to achieve is more complex, with other ligatures.) fonts.handlers.otf.addfeature{ name = "unfio", type = "chainsubstitution", lookups = { { type = "multiple", data = { [ "f_i" ] = { "f", "i" } } } } rules = { { after = { { "o" } }, current = { { "f_i" } }, lookups = { 1 } } } } } Could someone please explain to me what I did wrong ?

Hi all, I am looking for a way to make startstoplines likes this: This is a long line that breaks, the second line, the third line. So if a line in the poem is too long it shall break and indent. TIA juh

Minimum working example: \starttext I want to use the Mathjax_Fraktur font, which the font-manager on Ubuntu reports that it has. {\switchtobodyfont[Mathjax_Fraktur] .. but, this text doesn't show up in Mathjax_Fraktur.} \stoptext

Why are endnotes not working with ConTeXt-SBL?
by Joel 26 Dec '21

26 Dec '21

I am using the ConTeXt-SBL package for citations. I need to move my footnotes to the end of each article. According to the manual, I can suppress the placement of footnotes using two lines of code. I've added these to my minimal working code, placing \setupnote[footnote][location=none] in the header and \placenotes[footnote] where I want the endnotes to appear. It complains this error: "Undefined control sequence \doifendswithpunctelse" What did I do wrong? --Joel Code follows: \usemodule[publ-imp-sbl] \startbuffer [bib] @Article{na2006, title={Volcanoes \word{of} New Mexico}, year={2006}, journal={New Mexico Earth Matters}, publisher={New Mexico Bureau \word{of} Geology \word{and} Mineral Resources}, volume={6}, number={1}, location={Socorro, New Mexico} } @Book{clark1989, author = {Clark, William}, title = {Railroads \word{and} railroad towns \word{in} New Mexico}, publisher = {New Mexico Magazine}, year = {1989}, address = {Albuquerque, New Mexico}, isbn = {9780937206126} } \stopbuffer \usebtxdataset[bib.buffer] \setupbtx[dataset=default] \usebtxdefinitions[sbl] \setupbtx[sbl] \setupnote[footnote][location=none] \starttext \input knuth \cite[clark1989] \placenotes[footnote] \startchapter[title=Bibliography] \placelistofpublications \stopchapter \stoptext

Errors in source files return success
by Marco Patzer 26 Dec '21

26 Dec '21

Hi! ConTeXt can detect issues in the sources and report them on the console with the argument --errors or with \enabledirectives [logs.errors]. The return value is still “0” (=success) even with errors present. Right now I use a script that parses the log file and lets me know if a run has issues. However, it would be great if context could return a non-zero value if errors are present. I've found that \enabledirectives [logs.errors=missing characters] returns “1” if characters are missing. Lovely! Undefined control sequences always return 1 (a TeX thing I believe and not related to the macro package). But undefined control sequences don't show up on the console as the other errors do if general output (except errors) is silenced e.g. with context --silent --noconsole --nostatistics --errors <file> The question is, what other directives can be enabled that make context return a failure? Is there a way to return failure if *any* error is encountered or do they need to be enabled each individually? And is there a way to show hard TeX errors as undefined control sequences as a “possible issue” if output is silenced? MWE: %% enables logging of errors same as --errors AFAIK \enabledirectives [logs.errors] %% makes context return 1 on missing chars, great! %% \enabledirectives %% [logs.errors=missing characters] \starttext %% missing characters 𝒜 %% missing figure \externalfigure [foo] %% \end occurred inside a group at level 1 %% ### semi simple group … entered at line \startalignment [middle] foo %% missing references See \in{section}[sec:none]. %% undefined control sequence %% \undefined \stoptext Marco

Hi, When wrapping up before the weekend I uploaded a new lmtx (bottom floats fixed afaiks, but hat mechanism might see some improvements anyway next year; exit codes more reliable; some low level tracing; side float coming loose from section head issue solved; ...). I'm experimenting with some more efficient low level state info and in the process ran into an issue / interference with (also low level) attributes. I'm not sure if I solved it (work in progress, i need to run into another border case first which may take ages) but the test suite runs ok so ...
