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 29 Sep '20

29 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

scaling images
by Henning Hraban Ramm 27 Sep '20

27 Sep '20

Hi, I’m struggling with scaling images: \externalfigure[hacker][width=0.5\textwidth] looks right. If I use the scale / xscale / yscale options, the image gets smaller, regardless of height/width settings, i.e. with \externalfigure[hacker][width=0.5\textwidth,yscale=500,xscale=1000] It looks like scaling resets height/width settings and uses the image size defined by its resolution. In my current project, I can’t seem to manage to y-scale an image in a float, but I couldn’t reproduce that in a MWE yet, don’t know it it’s related. (both LMTX or MkIV, v. 2020.09.20 23:02) Hraban

Index range with page number suffix
by Duncan Hothersall 24 Sep '20

24 Sep '20

(Using mkiv.) I have an index in which some entries need suffixes on the page numbers, for which I have used processors. For index ranges, I need the page number suffix only to appear on the end page number, not the start page number. The below MWE produces an index entry: sausage 1i-2i What I need is: sausage 1-2i Is this possible? MWE \defineprocessor[important][right={\it{i}}] \starttext \samplefile{knuth} \startregister[index][sausage][important->sausage]{sausage} \dorecurse{6}{\samplefile{knuth}} \stopregister[index][sausage]{sausage} \samplefile{knuth} \page \placeindex \stoptext Thanks in advance, Duncan

Arabic support
by Denis Maier 24 Sep '20

24 Sep '20

Hi Just wondering what the current support for Arabic is. Does anyone know? My document works fine for Hebrew and I've just added a new fontfallbac: \definefallbackfamily[mainface][rm][Scheherazade] [range=arabic, force=yes, features=arabic] Bidi is activated with \setupdirections[bidi=global,method=unicode] Is that enough for Arabic? Or are there other things I need to take care of? E.g. searching in the mailing-list archive I found this message: https://www.mail-archive.com/ntg-context@ntg.nl/msg78573.html > You have to set the bidi settings again for the footnotes because > the notes mechanism resets many of these setups. > \startsetups[note:footnote] > \setupdirections[bidi=global] > \stopsetups > > \setupnote[footnote][setups=note:footnote] % align=righttoleft Is that still true? Anything else I need to be aware of? Best, Denis

Debug mode for XML processing
by Denis Maier 23 Sep '20

23 Sep '20

Hi, Is there are debug mode for XML processing? I'm thinking of something where the XML mapping gets applied to your XML, and you receive a tex file as the output. Could sometimes be easier to see where things go off the rails. Best, Denis

issue with interaction=all and \insertpages
by Pablo Rodriguez 23 Sep '20

23 Sep '20

Dear list, I have the following sample: \setuplayout[page] \setupinteraction [state=start, color=, contrastcolor=, focus=standard] \enabledirectives[references.border=red] \setupexternalfigures[interaction=all, method=pdf] \setupinteractionscreen[option={portrait, paper}] \starttext %~ \insertpages[http://gaceta.rsme.es/abrir.php?id=1495][width=0pt] \insertpages[GacRSocMatEsp.pdf][width=0pt] \stoptext I have some issues with it. 1. For some strange reason, the first \insertpages command with a remote file cannot deal with the interaction from the file (no internal or external links). 2. The local file includes internal destinations to page parts. After imposition, destinations to page for internal links cannot reach the page parts as links in original document do. 3. Even external links are converted. On last page, https://www.cs.umb.edu/~offner/files/pi.pdf is rewritten as https://www.cs.umb.edu/õffner/files/pi.pdf. Besides the rewritten link, would it be possible that links are added so they reach the same destinations as their source PDF document? Many thanks for your help, Pablo -- http://www.ousia.tk
