Hi Pablo, I'm resurrecting this thread, as I've just managed to get some progress on Windows with zint in LMTX. The thing is that you need 64-bit DLL, because LuaMetaTex is built for 64-bit architecture on Windows. As it is not available, I built 64-bit zint.dll (and zlib + libpng) from the latest git sources (2.11.1.9 (dev)), renamed it to libzint.dll and placed in appropriate place, as per the instructions. But there are still some problems... here is the excerpt from the log: modules > using user prefixed file 'libs-imp-zint' modules > 'zint' is loaded open source > level 2, order 3, name 'c:/Data/context/tex/texmf-context/tex/context/base/mkxl/libs-imp-zint.mkxl' resolvers > lua > loading file 'c:/Data/context/tex/texmf-context/tex/context/base/mkxl/libs-imp-zint.lmt' succeeded close source > level 2, order 3, name 'c:/Data/context/tex/texmf-context/tex/context/base/mkxl/libs-imp-zint.mkxl' optional > using library 'c:/Data/context/tex/texmf-win64/bin/lib/luametatex/zint/libzint.dll' zint > something went wrong: invalid result vector zint > something went wrong: invalid result vector backend > xmp > using file 'c:/Data/context/tex/texmf-context/tex/context/base/mkiv/lpdf-pdx.xml' pages > flushing realpage 1, userpage 1, subpage 1 zint > something went wrong: invalid result vector zint > something went wrong: invalid result vector zint > something went wrong: invalid result vector zint > something went wrong: invalid result vector zint > something went wrong: invalid result vector zint > something went wrong: invalid result vector I tested the library with the generated CLI tool, and I get the barcode images created. Although, png format is not working, I get file with length 0 and no error whatsoever. It could be that there is something wrong with the build, I'll try to figure out.

Issue with setupMPvariables
by Alexandre Christe 03 Sep '22

03 Sep '22

Dear all, I'm trying to reuse some MP code for several custom enumeration. However I can't make the overall setup work, needless to say different border colors for each enumeration though setupMPvariables. What am I missing? MWE: see attachment

Hmmm it seems the trick lies in adding \setupfloats [freeregion=no]

Question about text backgrounds
by Alexandre Christe 03 Sep '22

03 Sep '22

Hi, I just came across nofmultipars (which is great for splitting frames across pages, unlike a simple framed). Is there an equivalent for floats? The MWE would contain \startuseMPgraphic{mp:textFrame} begingroup; path p ; for i = 1 upto nofmultipars : p := (ulcorner multipars[i]) -- (llcorner multipars[i]) -- (llcorner multipars[i] xshifted .25cm) -- (ulcorner multipars[i] xshifted .25cm) -- cycle ; fill p withcolor "darkgreen" ; endfor; endgroup; \stopuseMPgraphic together with \definetextbackground [exampleFrame] [ mp=mp:textFrame, location=paragraph, ] Assuming I have between \starttextbackground[exampleFrame] and \starttextbackground[exampleFrame] also a figure in addition to text paragraphs. Would it be possible to also draw a rule next to it? Best regards, Alex

Is rendering furigana over horizontal or vertical japanese text doable in ConTeXt?

Typesetting furigana over kanji characters is common for japanese educational materials. Is this doable in ConTeXt?

Can't no break between a close punctuation and a open punctuation
by 黄复雄 03 Sep '22

03 Sep '22

I sent this email four days ago and it may not have been delivered? --------------------------------------------------------------------------------------- Dear Hans, I found that ConTeXt injected two infinity penalties between a close punctuation and a open punctuation, for example between `”` and `“`, or between `：` and `“`, so can not break at these places, as showed in following doc. But actually, we may sometimes need to do so. Please note that there is no space around full width punctuations in Chinese document. doc for example: ```lmtx \setscript[hanzi] \usetypescriptfile[mscore] \usebodyfont [mschinese,20pt] \showframe \starttext \dorecurse{5}{“好？！；”“：，。”} % linebreak sutck \dorecurse{30}{“我”} % linebreak sutck \dorecurse{30}{我} % linebreak work \dorecurse{30}{我。} % linebreak work \stoptext ``` What I see between any two consecutive punctuations are <penalty userpenalty> 10000 <glue userskip> 0 0 655500 <penalty userpenalty> 10000 <glue userskip> 0 655500 0 so nowhere to linebreak. Thanks.

How to make a reference go to an exact point of a section on a page?
by amano.kenji 02 Sep '22

02 Sep '22

I just created a reference to a \section with \in. Clicking the \in reference doesn't go to the \section, but to the page that has the \section. Does ConTeXt lack the ability to go to an exact point of a numbered element on a page?
