Customizing \cite alternatives
by Philipp A. 24 Feb '20

24 Feb '20

Hi List, I want the comma gone from “et al.” citations, and modify the cite alternatives: - [authoryear]: (Surname, et al., 2018) → (Surname et al., 2018) - [authoryears]: Surname, et al. (2018) → Surname et al. (2018) Also I’d like to configure how many names are the maximum before all except the first are replaced by “et al.” i.e. \setupcitething[maxauthors=3]: (One, Two, Three, & Four, 2018) → (One et al., 2018) How can I do this? I didn’t find anything in the publications manual: http://pragma-ade.nl/general/manuals/mkiv-publications.pdf Best, Philipp

Accessing raw titles in textcommand in TOC
by alephzorro 21 Feb '20

21 Feb '20

Hello, I would like to display titles differently in TOC than they appear in text. For example, MyChapter1 -> 1retpahCyM. Basically any highly non-trivial transformation that really needs Lua. I've written simple Lua macros before, but the following approach trying to define textcommand does not work since I can't find the way to pass the raw title to my transform function. \startluacode userdata = userdata or {} function userdata.mytransform(title) --context(title) --this is just fine, but isn't very useful context(string.reverse(title)) end \stopluacode \def\transformtitle#1% {\ctxlua{userdata.mytransform([==[#1]==])}} \setuplist[chapter][textcommand=\transformtitle] \starttext \completecontent \startchapter[title={Sample Chapter}] \stopchapter \stoptext When I print the actual title that is passed to mytransform, all I get is \currentlistentrytitle and I haven't succeed expanding it (and there's all kind of formatting stuff and so on going on I suppose). Sections have "deeptextcommand" which is somewhat what I'm after here, but I've not found similar option for TOC. So, is there a way to get just the raw titles? Jason C.

metapost: remapping colors of an SVG picture

Hello list, I tried this: \starttext \startMPcode picture p ; p := lmt_svg [ filename = "sample.svg" ] ; draw p ; color black_rgb ; black_rgb := ( 0, 0, 0 ) ; color red_rgb ; red_rgb := ( 1, 0, 0 ) ; remapcolor( black_rgb, red_rgb ) ; recolor p ; draw p shifted ( bbwidth(p) + 5mm, 0) ; \stopMPcode \stoptext but recolor gives an error: metapost log > >> picture metapost log > !

It's an attempt to use inkscape-made SVG graphics inside a CMYK workflow, without using color management. Naturally it would work under some constraints, but there's a lot of graphics you can do with Inkscape that falls inside these: - the number of colors in the input SVG should be limited, so that every color gets converted - no embedded bitmaps, only vector graphics - perhaps some other constraints on gradients, transparency, etc. A good alternative would be a remapper based on a custom lua function like this: function rgb2cmyk( r, g, b ) ... return c, m, y, k end Massi

Howto metapost textext set or change basepoint (origin) baseline of text
by Christoph Hintermüller 20 Feb '20

20 Feb '20

Hi I have the following problem. I convert a eps file using pstoedit into meta post file. When running this file through mptopdf the resulting pdf image is as expected. When i include, using the input command, the file within a startMPcode endMPcode or startMPpage stopMPpage after replacing simple draw <string>... by draw textext(<string) ... and compile the tex file with context than texts inside the graphic are schilfted bottom left. To mee it seems as textext uses a different basepoint/baseline of the text, than pstoedit assumed. Maybe in additon effects related to differences in fonts may be additional reason. My questions are What keywords do i have to enter in google or the context garden wiki search box to obtain examples and questions dealing with similar aspects How do i explicitly set the position of the text origin point within the textbox/lable box used by textext. eg. assume origin point bottom left, left on baseline, center in the middle etc. What else might i bee missing or having a wrong idea how things are done by netapost/metafun/context in this context?

Space between heading and paragraph in a description
by Kevin Kenan 19 Feb '20

How can I keep the space between the heading text and the paragraph from stretching/shrinking in a description? MWE that exhibits variable space between the heading (the defined word) and the paragraph text: \definedescription [definition] [headstyle=italic, indenting=1em, alternative=hanging, margin=2em, distance=1.5em, width=fit,] \starttext \definition{thelongheader} introducing bigwords mid-1990s, humans have taken an unprecedented step in Earthly annals by introducing not just exotic \definition{thelongheader} but actually inserting strange and exotic genes into the base operating systems of individual plants and animals, where they’re intended to do exactly the same thing: copy themselves, over and over. \definition{thelongheader} Since the late to mid-1990s, humans have taken a rare step in Earthly annals by introducing not just exotic flora or fauna from one \stoptext Thanks, -kk

Fonts not in preview of online print shop
by Jan U. Hasecke 19 Feb '20

19 Feb '20

Dear all, strange problem with my online print shop. I want to print 3 products. 1. Business Cards 2. Flyer 3. Poster All definitions for fonts, colors, color profiles and pdf version come from one an the same file (env-cd.tex). All PDFs passed the data check without problems, but Business Cards and Poster appear without any fonts in the final preview. Only the Flyer looks ok. The service staff is nice but has no idea where to look, never heard of ConTeXt. For the business cards the print shop will do paid manual enhancement. The poster is not as time critical. Any idea where to look? juh

font expansion MkXL vs. MkIV
by Pablo Rodriguez 18 Feb '20

18 Feb '20

Hi Wolfgang and Hans, I have the following sample: \setuppapersize[A5] \definefontfeature[default][default] [protrusion=quality, expansion=quality] \definefontfamily[mainface][rm][Source Serif Pro] \setupalign[hanging, hz] \setupbodyfont[mainface, 17pt] %~ \setupbodyfont[helvetica, 17pt] \starttext \input zapf \stoptext hz doesn’t work fine in MkXL, but it works fine in MkIV. I think the flow of characters is broken in MKXL. Some With TeX Gyre Heros (https://pdf.ousia.tk/mkiv-hz.pdf and https://pdf.ousia.tk/mkxl-hz.pdf) - "computer": line 5. - "basic": line 8. - "showing": line 10. With Source Serif Pro, also (https://pdf.ousia.tk/ssp-mkiv-hz.pdf and https://pdf.ousia.tk/ssp-mkxl-hz.pdf) - "publishing": line 2. - "about": line 4. - "between": line 10. I’m experiencing this wherever I use hz with MkXL. Sorry, but cannot the default values for quality font expansion be the same in MkIV and MkXL? Many thanks for your help, Pablo -- http://www.ousia.tk

Any plans for an active color management?
by Jan U. Hasecke 17 Feb '20

17 Feb '20

Hi all, I would like to come back to a discussion from 2018 on this list. After printing some flyers for my cooperative I come to the conclusion that color management *is* very difficult. In my eyes, the only way of getting good results seems to be the following process. My starting point are RGB colors as we are doing online first. So if I create a poster or a flyer I have to do this: 1. Decide which print shop will print the material. 2. Download and install the color profile for this print shop in ConTeXt. 3. Specify CMYK values by using transicc with the given profile 4. Define named corporate colors with these CMYK values for typography, colored background in ConTeXt. 5. Convert all RGB images to CMYK using the given color profile especially if they contain corporate colors. Now if we decide to use another print shop, the whole process has to start again. The result is that I end up with color settings for x different print shops and cmyk images for x different print shops. Are there any plans to automate these steps into ConTeXt? That would enable us to work in RGB the whole time. Only when creating a print pdf we would specify a color profile and ConTeXt would do the rest by converting all rgb values to cmyk values due to the given color profile. As this seems very complex I fear that there are no plans to do this. What alternatives I have? ========================= What if deliberately define my own cmyk values once and for all? Can I work with the same cymk values no matter what profile is used by the print shop? TIA juh

Thanks! \sc is more somthing mkii ... when type1 fonts (in an 8 bit universum) smallcaps and oldstyle and such meant using a different font nowadays one can turn them on/off as features and when you need them a lot you can even define an extra bodyfont variant from them and switch to that one when needed now, when smallcaps and oldstyle etc became features instead of font properties that didn't mean it always became easier because when opentype came around there was no 'recipe' or possibility to define what is default; for instance some fonts default to oldstyle in the sense that these shapes are in the default slots and you need to turn them off instead; also one needs to keep in mind that some features are language / script dependent and fonts differ in what they do default summary: see smallcaps as features but always look at what the font assumes and does by default; be prepared for inconsistencies (after all this is why we want/need control over what context does with a font) 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 -----------------------------------------------------------------
