Best way to store text for later use
by Denis Maier 02 Oct '20

02 Oct '20

Hi, For typesetting XML I'm wondering how to best store text for later use: I've tried using buffers, but this here doesn't work: ================== \startxmlsetups xml:article-meta \setupdocument [ pub-year=\xmlfilter{#1}{/pub-date/year/command(xml:article-meta:pubdate:year)}, volume=\xmlfilter{#1}{/volume/command(xml:article-meta:volume)}, doi=\xmlfilter{#1}{/article-id[@pub-id-type='doi']/command(xml:article-meta:doi)}, elocation-id=\xmlfilter{#1}{/elocation-id/command(xml:article-meta:elocation-id)}, title=\xmlfilter{#1}{/title-group/article-title/command(xml:article-meta:title-group:article-title)}, author={\AuthorList}, ] \startbuffer[abstract] \xmlfilter{#1}{/abstract/command(xml:article-meta:abstract)} \stopbuffer \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:article-meta:abstract \xmlflush{#1} \stopxmlsetups =================== This here works: ================== \startxmlsetups xml:article-meta \setupdocument [ pub-year=\xmlfilter{#1}{/pub-date/year/command(xml:article-meta:pubdate:year)}, volume=\xmlfilter{#1}{/volume/command(xml:article-meta:volume)}, doi=\xmlfilter{#1}{/article-id[@pub-id-type='doi']/command(xml:article-meta:doi)}, elocation-id=\xmlfilter{#1}{/elocation-id/command(xml:article-meta:elocation-id)}, title=\xmlfilter{#1}{/title-group/article-title/command(xml:article-meta:title-group:article-title)}, author={\AuthorList}, abstract=\xmlfilter{#1}{/abstract/command(xml:article-meta:abstract)}, ] \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:article-meta:abstract \xmlflush{#1} \stopxmlsetups =================== But has using a variable for the abstract any drawbacks? (The abstract might contain multiple paragraphs.) Best, Denis

library 'uni' is unknown
by Susanne G. Loeber 01 Oct '20

01 Oct '20

Dear Reader, https://wiki.contextgarden.net/Symbols shows predefined symbol sets. The uni and wasysym are unknown. Hereby my example: \usesymbols[mvs] \usesymbols[uni] \usesymbols[wasysym] %% \usesymbols[ifsym] \starttext \par Show entire set martinvogel 1 \showsymbolset[martinvogel 1] \par Show YinYang symbol from martinvogel 2. \crlf \symbol[martinvogel 2][YinYang] %% \symbol[Alpine Symbol][Flag] \stoptext Console output fonts > symbols > library 'mvs' loaded fonts > symbols > library 'uni' is unknown fonts > symbols > library 'wasysym' is unknown The ultimate goal is to show a flag from the alpine symbol set from ifsym. However, I will settle with a flag from uni if it means I don't have to install files. Kind regards, Susanne

no frontmatter head on recto page
by jbf 30 Sep '20

30 Sep '20

For some reason that I cannot work out, the recto page header is not appearing in frontmatter sections like Foreword. It is important to note that for this item I am using: \definehead [foreword] [chapter]... \setuphead [foreword] [frontpartlabel=foreword, conversion=empty] Then starting this section in the main body with \startforeword...\stopforeword. As 'foreword' is based on chapter, I thought it would all work correctly given that I already have: [{\hfill\getmarking[chapter]\hfill}][] [{\hfill\documentvariable{metadata:title}\hfill}][] And I also have: \setupsectionblock[frontpart][page=yes] in case that is important as well. I am getting the verso page header (the book's title, obviously coming from the \documentvariable{metadata:title}), but not the recto header (in this case 'Foreword'). What am I doing wrong? I tried two solutions to solve the problem, neither worked: 1. In \setuphead I thought perhaps I might need to add placehead=yes, but that did nothing. 2. I also tried [{\hfill\getmarking[chapter, foreword]\hfill}][] in case I needed to add in 'foreword', having defined it as a head. That did nothing either. Any clues as to what I am missing? Julian

Tagged export breaks r2l alignment in tabulate
by Denis Maier 30 Sep '20

30 Sep '20

Hi, this example produces correctly aligned right-to-left text: ============ \setupalign[verytolerant,stretch] \setupdirections[bidi=global,method=unicode] \starttext \starttabulate[|p|p|] \NC Text \NC Translation \NC\NR \NC\setupalign[r2l]\input ward \NC\input ward \NC\NR \stoptabulate \stoptext ============== But, this here fails: ============ \setupalign[verytolerant,stretch] \setupdirections[bidi=global,method=unicode] \setupbackend[export=yes] \setupstructure[state=start,method=auto] \starttext \starttabulate[|p|p|] \NC Text \NC Translation \NC\NR \NC\setupalign[r2l]\input ward \NC\input ward \NC\NR \stoptabulate \stoptext ============== Why is that? And what can I do about it? (I need tagged pdf for PDF/A compliance.) Best, Denis

Unwanted whitespace at beginning of document
by Denis Maier 30 Sep '20

30 Sep '20

Hi, I have ended up with unwanted whitespace at the beginning of my document. The environment definition is already quite complex, so I cannot easily tell where the whitespace is coming from. Any advice how I could track that down? Are there some tricks for this? Best, Denis

page counter problem
by Alan Bowen 30 Sep '20

30 Sep '20

he page counter does not increase in the first iteration an PDf inclusion but seems to work properly after that. Have attached a sample file (69K) that will serve to show the problem—at least, on my machine. \starttext \setupexternalfigures[location=default] \setuplayer[preset=middlebottom, method=overlay]{} \setcounter[userpage][101] \noheaderandfooterlines \getfiguredimensions[HannahBW.pdf] \dorecurse{\noffigurepages} {\vbox to \paperheight {\vskip-\dimexpr\headerheight+\headerdistance+\topspace\relax \hbox to \hsize {\hskip-\backspace \layeredtext[] [boffset=3pc] {\red\userpagenumber} {\externalfigure[HannahBW.pdf][page=#1]}% \hss}% \vss} } \dorecurse{\noffigurepages} {\vbox to \paperheight {\vskip-\dimexpr\headerheight+\headerdistance+\topspace\relax \hbox to \hsize {\hskip-\backspace \layeredtext[] [boffset=3pc] {\red\userpagenumber} {\externalfigure[HannahBW.pdf][page=#1]}% \hss}% \vss} } \stoptext

correct vertical alignment in ToC
by jbf 30 Sep '20

30 Sep '20

A quick look at the attached pdf extract from my current Table of Contents will demonstrate the problem. I need authors names, chapter titles and/or date range to line up correctly underneath each other, but because of the definitions I am working with (see below how the current result has been acheived) I do not know how to get these precise margin (I presume?) distances. So, for example, the author for the Preface needs to line up directly under the author for the Foreword. And the title for Chapters One/Two and the date range for Chapter Three likewise. The 'Context' item is a \section and I have got that more or less to line up by using an \hspace definition, but I know that using two very different definitions is likely to cause problems. (Alternatively, they could all line up under the title for Chapter One, so a bit further in. What *has to happen* is that they all line up accurately under each other, whichever solution I use). My real problem is that I do not know how get these specific distances from the left-hand side using the definitions I have. If I knew how to get, say, 3cm in from the margin for Chapter authors/titles/date ranges (given the definition below) and section authors (given its definition below), I could solve this problem, but everything I have tried does not seem to work. Wolfgang had given me the ChapterListCommand definition, and I think Hraban the SectionTocentry: (1) CHAPTERLISTCOMMAND \define[3]\ChapterListCommand {\hbox\bgroup \hbox to 2.5cm{\currentlistsymbol\hss}% number + labeltext \vtop\bgroup \hsize\dimexpr\makeupwidth-2.5cm\relax \doifsomething{\rawstructurelistuservariable{year}} {{\structurelistuservariable{year}}\crlf}% \currentlistentrytitle % title \doifsomething{\rawstructurelistuservariable{author}} {\crlf{\structurelistuservariable{author}}}% \hfill\currentlistentrypagenumber % pagenumber \egroup \egroup} Is there somewhere in here that I can specify my distances other than the \hbox 2.5cm? Note that I obviously also have (e.g. for the Preface, but I have others for Foreword, etc.): \setuplist [preface] [label=preface, alternative=command, command=\ChapterListCommand] (2) SECTIONTOCENTRY \definehspace[twoem][2.5 em] \define[1]\SectionTocEntry{% #1\hspace[twoem]% title \structurelistuservariable{author}% } \setuplist[section][ textcommand=\SectionTocEntry, margin=.5cm] The [twoem] definition (in fact it is 2.5 em) was how I got the 'Context' author to roughly line up under the other items, but I have noticed that in some repetitions of this section, they do not line up exactly even so. Hope somebody can help - in the end I suppose I can open it in a PDF editing program and shift items under each other, but I want to achieve the correct result using ConTeXt, understandably. Julian

OK, I Don't Quite Understand \definefontfamily
by Michael Urban 29 Sep '20

29 Sep '20

I don't seem quite able to put it all together, forgive the question. I have a 'Bookman' font setup, pretty vanilla: \definetypeface [Bookman] [rm] [serif] [bonum] [sl=name:unituscndboldoblique] \definetypeface [Bookman] [tt] [mono] [modern] [default] \definetypeface [Bookman] [ss] [sans] [unitus] [default] \definetypeface [Bookman] [mm] [math] [modern] [default] (Unitus is the fontsite 500 'Univers' substitute, works fine) Now, the built-in gyre bonum font doesn't have a slanted/oblique variant, so if I have Bookman as my main body font, \sl produces (unsurprisingly) the same result as \it, TexGyreBonum-Italic. If I want \sl to summon Latin Modern for the variant, I have tried variations on \definetypeface [Bookman] [rm] [serif] [bonum] [sl=file:Latin Modern Roman Slanted] but to no avail — not helped by the fact that the \definetypeface contextgarden page doesn't have any pointer to just what that fifth argument can contain. How do I accomplish this?

numbering pages included by \copypages
by Alan Bowen 28 Sep '20

28 Sep '20

I need to include several documents in a single paginated file. Treating the source file (.tex) of each document as a component file in a .prd file is one way to go. But I was wondering if it might be possible to do get the same result using the .pdf files of each document instead. \copypages is promising: it includes the. pdf files and the counter in the resultant .prd file is correct. But what I still have to get is the page number on all pages of the included .pdf files except the first page in each. I looked at \startpagefigure but that would be a very cumbersome way to go since there over 350 pages to include, given that it handles only one page at a time. I hope that this makes sense. Any suggestions or pointers will be most welcome. Alan
