can't accent/fake characters in euler font
by a badin 19 May '22

19 May '22

Hello all, typesetting accented characters in eulernova font does not seem possible to me. Is it really impossible? The other math fonts (stix/xits) do it. I'm using Context LMTX 2022.01.21 20:13 \starttext \switchtobodyfont[eulernova] \startlines euler: 1 - č 2 - \ccaron 3 - \v{c} \stoplines \switchtobodyfont[stixtwo] \startlines stix: 1 - č 2 - \ccaron 3 - \v{c} \stoplines \stoptext In the end I'd like to be able to make more custom characters, e.g. Ĺ, ô, ä, ... therefore I wanted to read about how those could be made, but the wiki points to missing files: http://source.contextgarden.net/enco-acc.tex http://source.contextgarden.net/tex/context/base/enco-def.tex Any help appreciated, Andrej Badin

overthinking overprinting
by Henning Hraban Ramm 19 May '22

19 May '22

A question on TeX-D-L reminded me to look into this subject. At the moment, there is \setupcolors[intent=overprint|knockout] with \startoverprint|knockout, as defined in colo-ext.mkxl|mkiv. I’m not sure what that does as a general setting – usually you need overprinting for black text and lines in CMYK documents. There are special cases where you want other (spot) colors to overprint, but that’s quite rare, and I can use transparency features to achieve the same (a=multiply) in an even more flexible way – as long as I don’t need a format like PDF/X-3 that doesn’t allow transparencies. If I declare such a format, ConTeXt just switches off transparencies and doesn’t try to emulate (“flatten”) them as e.g. InDesign does. So it would be nice if I could e.g. \definecolor[OPred][m=1,y=1,intent=overprint] OTOH there are cases where I want a black area or text to knockout the background, these might work with \startknockout etc. When I try my example: \useMPlibrary[dum] \setupcolors[ rgb=no,cmyk=yes, intent=overprint,% or knockout ] \setupbodyfont[modern,ss,18pt] \starttext \definecollector[Test] \setcollector [Test] {\externalfigure[none][width=8cm,height=6cm,frame=on]} \setcollector [Test] [corner=middle,location=middle] {{\bf Toast}} \setcollector [Test] [corner={left,top},location={right,bottom}] {\framed{LT}} \setcollector [Test] [corner={left,bottom},location={right,top}] {\framed{LB}} \composedcollector{Test} \stoptext ... then the text is “knocked out” regardless how set the intent. It also doesn’t help to use \startoverprint for the Text. The attached screenshot shows the color separation preview from Acrobat Pro 9. Is this broken or intended to be used differently? Hraban

Rendering Standalone MetaPost Graphics with ConTeXt
by Vincent Hennebert 19 May '22

19 May '22

I’d like to use MetaPost to generate all sorts of standalone graphics (ultimately converted to SVG). For various reasons (among others, MetaFun and advanced text processing) I want to use MetaPost as embedded in ConTeXt rather than a standalone installation. ---- metapost.mp ---- fill fullcircle scaled 10cm; ---- Whether I run context metapost.mp or mtxrun --script metapost metapost.mp I get a PDF document that contains no page. The mtxrun version generates the following temp file: ---- mptopdf-temp.tex ---- \starttext \startMPinclusions fill fullcircle scaled 10cm; \stopMPinclusions \stoptext ---- Looking at the wiki, it seems that \startMPinclusions is not meant to actually render any content, just to include MetaPost code like function definitions. I guess I would have expected \startMPpage instead. Am I doing something wrong, or is that an error in ConTeXt? Thanks, Vincent

Is there a possibility to split it up into "professional" during the week and "hobbyist" over the weekend so people could come for just the weekend, or the whole week? For most of us it *is* a hobby and the meeting kind of holidays. IMO meeting over the whole week is a big part of the appeal, otherwise we couldn’t fit all the interesting stuff into the schedule and the personal interaction also would fall short. I remember we had a similar split when we combined with EuroTeX. I was new to the community at that time, and I found the sudden influx of people over the weekend very confusing. YMMV It was always possible to register and come for just some days. We discourage it, since it disturbs the community experience, pickup is additional effort, and we often must pay the venue for the whole week (it depends). In 2022 the weekend would mean: maybe a talk or two on Friday, CG members meeting on Saturday morning, excursion for the rest of the day and nothing but departure on Sunday. In other years we met e.g. from Sunday to Saturday, and on the first day we are busy arriving and setting up. BTW it looks like Jano will host us in Sibřina again in September of 2023. And we’re discussing “uncharted territory” for 2024. Hraban

ConTeXt meeting 2023(!)
by Henning Hraban Ramm 18 May '22

18 May '22

Hi y’all, at the latest online meeting as well as within the CG board, we were discussing the ConTeXt meeting in 2023, since nothing is planned yet. [date] The usual fall date makes it difficult for students and teachers to attend. We were discussing a date in August (or even July). Would that make a difference for you? What would you prefer? One argument against a date within the summer holidays is that many venues are booked for years in advance, but we got at least one offer (see below). [place] While we were due to go to Eastern Europe again, it looks like Jano as well as Mojca are too busy to organize a meeting. (And I’m very sorry if I misunderstood!) Please stand up whoever would like to organize next year’s meeting! Otherwise I might invite you to Maibach again (where we were in 2017), they told me they still have open slots in summer. Hoping for many more exciting ConTeXt meetings, Hraban 👉 https://meeting.contextgarden.net 👈

PDF/A-3, XMP and Factur-X
by Henning Hraban Ramm 18 May '22

18 May '22

Hi again, I’m looking into extending my ConTeXt-made invoices with embedded XML data according to the DE/FR Factur-X standard (in Germany also known as ZUGFeRD). Does anyone have some experience with that? For that, I need PDF/A-3(a) compliant documents – current documentation is only on PDF/A-1(a), but that doesn’t seem to be the problem. Now I’m supposed to put additional information into the XMP metadata. I found lpdf-xmp.lua; but it seems like I can’t just use \startluacode lpdf.addtoinfo("TEST","Hraban was here!") lpdf.addxmpinfo("UStID","123456") \stopluacode Would I need to add my tags to the mapping table of lpdf-xmp.lua? Or circumvent it after a look at the function concerned: function lpdf.addxmpinfo(tag,value,check) local pattern = permitdetail(tag) if type(pattern) == "string" then xmlfillin(xmp or valid_xmp(),pattern,value,check) end end If I try to use xml.fillin, I apparently need the name of the current xml file, but valid_xmp is a local function. If just use the default... xml.fillin("lpdf-pdx.xml","metadata","UStID","123456") ... at least I find no traces of that key in the extended metadata dialog of Acrobat Pro 9. I also tried different values like "xmp" instead of metadata. Clearly I don’t understand what I’m doing here ;) Is there a check against some schema involved? It looks like I should include an additional XMP schema for Factur-X with the URI "urn:factur-x:pdfa:CrossIndustryDocument:invoice:1p0#", prefix "fx". How can I do that? This is the example from the docs: <rdf:Description rdf:about="" xmlns:fx="urn:factur-x:pdfa:CrossIndustryDocument:invoice:1p0#"> <fx:DocumentType>INVOICE</fx:DocumentType> <fx:DocumentFileName>factur-x.xml</fx:DocumentFileName> <fx:Version>1.0</fx:Version> <fx:ConformanceLevel>EXTENDED</fx:ConformanceLevel> </rdf:Description> Then I’d use \attachment to include my "factur-x.xml" invoice (that I must generate from my Lua invoice code), but that’s a task for another day ;) Hraban

Does writing \emdash versus writing "—" in the source file impact the displayed output?
by Joel 18 May '22

18 May '22

I have been using \endash, \emdash, and \figuredash in place of the various types of dashes in my document, \quotation{} around quotes, etc. so basically the only really punctuation appearing in the tex file are periods, commas, semi-colons, colons, apostrophes, and question-marks. The problem I have is when copying to a tool like Grammarly for grammar checks, these special symbols throw off the grammar-checking tools. Does ConTeXt render and display these punctuation differently when I write them in the coded form, versus simply writing in the unicode directly? --Joel

Can I just put a footnote without marking in the main text?
by Zhichu Chen 18 May '22

18 May '22

Hi everybody, After some attempts to put footnotes in a mixed 1&2 columns layout, I decide to put marks in the one-column environment and flush them when entering the two-column environment. The code is ugly but the result is acceptable. Except that the invisible footnote marks do generate something in the main text, so there's a blank line for each footnote. Here's an MWE: ============================================= \definenote[address] \setupnote[address][rule=off,location=text] \definenote[putjustmark] \setupnote[putjustmark][location=none] \setupnotation[putjustmark][numberconversion=set 2] \definenote[putjustnote]%[footnote] % if footnotes need to be grouped, uncomment the second argument and the line after \the\titlefootnotes \setupnote[putjustnote][textcommand=\gobbleoneargument] \setupnotation[putjustnote][numberconversion=set 2] \newtoks\titlefootnotes \def\thanks#1{\putjustmark{#1}\appendtoks \putjustnote{#1} \to \titlefootnotes} \def\email#1{\putjustmark{#1}\appendtoks \putjustnote{#1} \to \titlefootnotes} \appendtoks \setcounter[footnote][0] % this looks stupid because it has no effect %\setupnotation[footnote][numberconversion=numerals] \to \titlefootnotes \definenamespace [addr] [type=module, name=address, command=yes, setup=list, parent=addr, ] \define[1]\useaddress {\setnotetext[address][#1]{\namedaddressparameter{#1}{name}}} \starttext \defineaddress[fst][name={Name of Institute or Affiliation, City, Country}] \defineaddress[snd][name={Name of Secondary Institute or Affiliation, City, Country}] \processcommacommand[fst,snd]\useaddress The Title\thanks{Work supported by somebody.} Me\email{myemail(a)some.where}\high{,}\note[address][fst]\high{,}\note[address][snd] \placenotes[address] \blank[medium] \startcolumns \the\titlefootnotes %\setcounter[footnote][0] % why it's necessary to set the counter outside the token if I define [putjustnote] as [footnote]? test\footnote{test} \input knuth \stopcolumns \stoptext =============================================
