Formulas in TABLE with character alignment
by Axel Kielhorn 09 Oct '18

09 Oct '18

Hello, I decided to use TABLE because I may need some more complex layouts later and want to use just one way to define a table. One of the great things about TABLE is the possibility to align columns. The table below works fine when I comment the first \bTR line. With the first line the result is strange. I need some way to protect the words in the header, putting them in an \mbox didn’t help. \starttext { \setupTABLE[row][each][frame=off] \setupTABLE[c][1][width=0.1\textwidth] \setupTABLE[c][2][width=0.1\textwidth,alignmentcharacter={,},aligncharacter=yes,align=middle] \setupTABLE[c][3][width=0.1\textwidth,alignmentcharacter={,},aligncharacter=yes,align=middle] \setupTABLE[c][4][width=0.1\textwidth,alignmentcharacter={,},aligncharacter=yes,align=middle] \bTABLE \bTABLEbody \bTR \bTD \eTD \bTD \chemical{NH_3} \eTD \bTD R407C \eTD \bTD R134a \eTD \eTR \bTR \bTD \math{t_s} \eTD \bTD \math{p_s} \eTD \bTD \math{p_s} \eTD \bTD \math{p_s} \eTD \eTR \bTR \bTD \unit{Celsius} \eTD \bTD \unit{bar} \eTD \bTD \unit{bar} \eTD \bTD \unit{bar} \eTD \eTR \bTR \bTD \unit{+35} \eTD \bTD 13,50 \eTD \bTD 14,47 \eTD \bTD 8,865 \eTD \eTR \bTR \bTD \unit{-40} \eTD \bTD 0,717 \eTD \bTD 0,956 \eTD \bTD 0,516 \eTD \eTR \eTABLEbody \eTABLE } \stoptext Greetings Axel

Using context.setupexternalfigures
by moi＠gilleswaeber.ch 09 Oct '18

09 Oct '18

Hi, I'm trying to setup the path for images using environment variables but calling context.setupexternalfigures does not work for me. I am using the latest version 2018.10.08 17:44 on Windows. \directlua{ % This one works fine %context("\\setupexternalfigures[directory={images, " .. os.getenv('IMG_PATH'):gsub('\\', '/') .. "}]") % Those do not (state: unknown) context.setupexternalfigures({directory = {{'images', os.getenv('IMG_PATH'):gsub('\\', '/')}}}) context.setupexternalfigures {directory = {{'images', os.getenv('IMG_PATH'):gsub('\\', '/')}}} context.setupexternalfigures({'images', os.getenv('TEX_PATH'):gsub('\\', '/')}) } \starttext \externalfigure[cow] \stoptext Called with $env:IMG_PATH = 'D:\Applications\Context\tex\texmf-context\tex\context\sample\common'; context test.tex Additionally, using a path with non-ascii symbols in environment variables does not seem to work at all but this is not a big issue for me. How should I call context.setupexternalfigures? Best regards, Gilles

Can anyone connect context to R or python?
by Kelley, Claire 08 Oct '18

08 Oct '18

Hi All, I am very interested in creating pdf documents using Context with calculations done in R or Python and then added into the document. If you were using traditional latex this could be accomplished through R markdown or Sweave- is there any way to connect these to Context? Best, Claire

OpenType optical bounds not working
by Pablo Rodriguez 08 Oct '18

08 Oct '18

Hans, I reported this issue some time ago. The new fontloader crashed when the opbd feature was invoked. That issue was fixed, but opbd is still not working, as shown in the following sample: \definefontfeature[default][default][protrusion=quality, opbd=yes] \definefontfamily[mainface][rm][Linux Libertine O] \setupbodyfont[mainface, 300pt] \setuppagenumbering[location=] \setupalign[hanging] \showframe \starttext W \stoptext Could you fix the opbd feature? Many thanks for your help, Pablo -- http://www.ousia.tk

Need help with project: TeX capacity exceeded
by Axel Kielhorn 05 Oct '18

05 Oct '18

Hello, this is my second try to start with context and I can’t even do the first step. I’m planing to convert a large but simple document to context. The document consists of 3 Parts. Each part has several chapters. Thus I started to build a project with three products, see enclosed archive. According to my understanding I should be able to context c_01 to get one chapter context prd_A to get one product context project_ecm to get the whole book. The first two steps lead to circular inclusion and the TeX capacity error. The last step doesn’t load the products and creates no files. I got my information from https://wiki.contextgarden.net/Project_structure and think I adapted them correctly, but obviously I didn’t. I included the log files in case there is something broken with my setup. Greetings Axel

Magic Elimination
by Sebastian Miele 05 Oct '18

05 Oct '18

ConTeXt contains a lot of magic. Is there a very plain-ish X between iniLuaTeX and MKIV, plus a tool that does the following: Given an MKIV document, reduce the document to X, especially including a solid deal of dead code and magic elimination? I.e. a tool that leaves a "How it can be done without magic directly in X". There is a tool named (la)texdef. Is there something like contextdef? What is the quickest way to find the definition of a macro (on the command line and/or in Emacs)?

faking smallcaps font with font features and fallbacks
by mf 04 Oct '18

04 Oct '18

Hello list, i'm trying to add a smallcaps variant to the MyriadPro font, since it does not implement the smcp opentype feature. My strategy: - "transplant" the uppercase letters of the MyriadPro-Regular into the lowercase letters of the same font with a font fallback that scales down the glyphs ("FakeSansCaps" in the following source) - since the scaled down glyphs get also thinner traits, embolden them with a font feature effect ("emboldened" in the following source) to make them consistent with the "real" uppercase letters What is not working: i don't know how to map the uppercase letters to the lowercase range; i tried to specify an offset of -32 in \definefontfallback[FakeSansCaps][SansEmboldened][0x61-0x7a][rscale=.8,force=yes,offset=-32] but it does not work. Here's the minimal (not) working example: \starttypescriptcollection [myriadpro] \definefontfeature[emboldened][effect={width=0.1,delta=0.4,factor=0.3}] \starttypescript [sans] [myriadpro] \definefontsynonym [Sans] [file:MyriadPro-Regular.otf] [features=default] \definefontsynonym [SansItalic] [file:MyriadPro-It.otf] [features=default] \definefontsynonym [SansBold] [file:MyriadPro-Bold.otf] [features=default] \definefontsynonym [SansBoldItalic] [file:MyriadPro-BoldIt.otf] [features=default] \definefontsynonym [SansSlanted] [file:MyriadPro-It.otf] [features=default] \definefontsynonym [SansBoldSlanted] [file:MyriadPro-BoldIt.otf] [features=default] \definefontsynonym [SansEmboldened] [Sans] [features=emboldened] \definefontfallback[FakeSansCaps] [SansEmboldened] [0x61-0x7a] [rscale=.8,force=yes] % offset? \definefontsynonym [SansCaps] [file:MyriadPro-Regular.otf] [fallbacks=FakeSansCaps] \stoptypescript \starttypescript [myriadpro] \definetypeface [myriadpro] [ss] [sans] [myriadpro] [default] \stoptypescript \stoptypescriptcollection \usetypescript[myriadpro] \setupbodyfont[myriadpro,ss] \starttext % scaled up 4 times to appreciate the thickness compensation \scale[sx=4,sy=4]{\sc SoMe CaMeLcAsE TeXt.}\par \stoptext
