My question is then how do you usually run mtxrun: 1) always writing the full path of the correct executable, 2) avoid putting [lmtx path]/bin in PATH, 3) putting [lmtx path]/bin _after_ [lmtx path]/tex/texmf-linux-64/bin in the PATH I'm asking here because option 1 is correct but not very handy, while 2) and 3) are different from what the installer says and they seemed to give other problems when I tried them. Thank you in advance, LD

I'm on linux but I'd prefer not to use this method, because I use context both from the command line and from my editor (emacs with auctex) and I have scripts that change my environment to be able to switch between different context versions (lmtx, texlive, ...). In any case, I'll think about this solution and it could be useful to other people, too. LD

If this works well, then it could be useful to change the message shown at the end of the installation process, as Rudolf already suggested in this thread. By the way, you seem to imply that [lmtx path]/bin should be in the PATH during updates. I didn't know that and I'm sure I've updated several times without it: I have different environments to be able to switch between different versions of context (lmtx, the old one, that from texlive...), I never check which one I'm in before updating lmtx and the installer does not complain.

Repeat backgrounds on slides
by juh 15 Feb '20

15 Feb '20

Hi all, I am a little bit confused as I never had this problem, although I often use backgrounds and layers. \definelayer[bg:hs2020-mond] [x=0, y=0, width=\paperwidth, height=\paperheight] \setlayer[bg:hs2020-mond] [x=0mm, y=0mm] {\externalfigure[background.jpg][height=\paperwidth]} Ususally I call the background after a head command like \starttitle or when I create slides like this \startslide[title={foobar}] \setupbackgrounds[page][background=bg:hs2020-mond] ... \stopslide The problem is that I cannot call the background on another slide. It seems as if the layer is gone after the first usage. So in this example the second bg:hs2020-mond would not print. \startslide[title={foobar}] \setupbackgrounds[page][background=bg:hs2020-mond] ... \stopslide \startslide[title={foobar}] \setupbackgrounds[page][background=bg:other] ... \stopslide \startslide[title={foobar}] \setupbackgrounds[page][background=bg:hs2020-mond] ... \stopslide TIA juh -- Autoren-Homepage: ......... http://literatur.hasecke.com Satiren & Essays: ......... http://www.sudelbuch.de Privater Blog: ............ http://www.hasecke.eu Netzliteratur-Projekt: .... http://www.generationenprojekt.de

Label in externalfigures
by Jan-Erik Hägglöf 14 Feb '20

14 Feb '20

Dear Members! I have a question on how to achieve something like this. \IncludePicture[picture.pdf][xpos=2, ypos= 4, label=some text] I know there is a similar function in the simple slides module but I need it in my documents, often exams to my students, so caption is mainly not necessary. The background to this is that I often creating pictures in Inkscape and export it to pdf but sometimes I do screenshots and save it in .png or .pdf format. So I just want to put labels in it like a layer in same size as the included picture. Or is this something that’s already solved so "reinventing wheel" is unnecessary? Thanks in advance Jan-Erik

attachments working again (issue with /EmbeddedFiles)
by Pablo Rodriguez 14 Feb '20

14 Feb '20

Hans, many thanks for having fixed the issues with attachments (in latest beta from 2020.02.07 18:36). I haven’t tested attachments with PDF/A-3a. But there is still an issue with /EmbeddedFiles. MWE: \setupinteraction[state=start] \starttext \startTEXpage[offset=1em] a\attachment[file=abdfaeasd.txt, name=hola, method=hidden] \contextversion \stopTEXpage \stoptext File name is changed: 2 0 obj << /AFRelationship /Unspecified /EF << /F 1 0 R >> /F (hola.txt) /Type /Filespec /UF <FEFF0068006F006C0061002E007400780074> >> endobj But embedded names have the name from the file, leaving it unchanged (abridged version): 18 0 obj << /EmbeddedFiles << /Names [ (abdfaeasd.txt) 2 0 R ] >> /Type /Names >> endobj Could you fix the name change for /EmbeddedFiles? Many thanks for your help, Pablo -- http://www.ousia.tk

Global \setup has no effect while ad-hoc setting does
by Exp 13 Feb '20

13 Feb '20

Dear list, I want to prevent an overfull hbox caused by an inline typing by making the alignment very tolerant, but it didn't work: ``` \setupframedtext[ width=broad, align={verytolerant, stretch} ] \starttext \startframedtext%[align={verytolerant, stretch}] xx. xxxxxxxxx xxxx xxxxxx-xxxx xx xxxx, xx xxxxxxx xxx xxxxxx \type{yyyyyyyyyyyyyyy}. xxxx xxxx xxxxxxxxxxxxxx xxxxx xxxx xxxxx xx xxxxxxxxx xx xxxxxxxx xxxxxxx. \stopframedtext \stoptext ``` while the following works: ``` \setupframedtext[ width=broad, align={verytolerant, stretch} ] \starttext \startframedtext[align={verytolerant, stretch}] xx. xxxxxxxxx xxxx xxxxxx-xxxx xx xxxx, xx xxxxxxx xxx xxxxxx \type{yyyyyyyyyyyyyyy}. xxxx xxxx xxxxxxxxxxxxxx xxxxx xxxx xxxxx xx xxxxxxxxx xx xxxxxxxx xxxxxxx. \stopframedtext \stoptext ``` ConTeXt version: `mtx-context | current version: 2019.03.21 21:39`. Any help would be appreciated. Best, Exp

Color Profiles in lmtx
by juh 13 Feb '20

13 Feb '20

Hi all, again I have a question concerning color profiles. I have this to load the ISO Coated v2 300% profile. \setupbackend[ format=PDF/X-3:2003, intent={ISO Coated v2 300\letterpercent\space (ECI)}, ] \setupcolors[cmyk=yes,rgb=no,] But is this profile part of the new lmtx version? I get this in my logs backend > profiles > profile specification 'ISO Coated v2 300% (ECI)' loaded from '/home/juh/context-linux-64/tex/texmf-context/colors/icc/context/colorprofiles.xml' But I am not sure whether the profile is really loaded. In the old context distribution I had to put the profile in texmf-local. There is this in lmtx: ~/context-linux-64/tex/texmf-context/colors/icc/profiles$ ls -l insgesamt 3652 -rw-r--r-- 1 juh juh 416 Jan 6 16:32 default_gray.icc -rw-r--r-- 1 juh juh 1992 Jan 6 16:32 ecirgb_v2.icc -rw-r--r-- 1 juh juh 700 Jan 6 16:32 ecirgb_v2_iccv4.icc -rw-r--r-- 1 juh juh 1829093 Jan 6 16:32 isocoated_v2_300_eci.icc -rw-r--r-- 1 juh juh 1829077 Jan 6 16:32 isocoated_v2_eci.icc -rw-r--r-- 1 juh juh 3144 Jan 6 16:32 srgb.icc -rw-r--r-- 1 juh juh 60960 Jan 6 16:32 srgb_v4_icc_preference.icc I am not sure if the file name matches as in profiles.xml we have this with mixed upper and lower cases: <profile> <filename>ISOcoated_v2_300_eci.icc</filename> <colorspace>CMYK</colorspace> <class>prtr</class> <id>FOGRA39</id> <info>ISO Coated v2 300% (ECI)</info> <checksum>e14f5db955711d914d877df35ad7a1b5</checksum> <version>24000000</version> <url>http://www.color.org</url> <outputcondition>Offset printing, according to ISO 12647-2:2004/Amd 1, OFCOM, paper type 1 or 2 = coated art, 115 g/m2, tone value increase curves A (CMY) and B (K)</outputcondition> </profile> Is there a linux tool to test if the correct profile is part of the pdf? Any hints?

mtxrun
by Rudolf Bahr 12 Feb '20

12 Feb '20

Hello ConTeXters! LuaMetaTeX, Version 2.03.15 ConTeXt ver: 2020.02.07 18:36 MKIV beta fmt: 2020.2.10 works well doing my usual tasks. Now, I put an .otf-font into ".../tex/texmf-local/", and made mtxrun --generate mtxrun --script fonts --reload mtxrun --script fonts --list --all --pattern=<pattern*>, but didn't get the expected information on the new font from the last command. So I investigated the output of the first two commands in more detail and found: 1. mtxrun --generate: resolvers | resolving | warning: no lua configuration files found resolvers | resolving | no texmf paths are defined (using TEXMF) By the way, "TEXMF" seems to be a mtxrun variable and hasn't directly to do with the environmental variable "TEXMF" which gets extinguished. 2. mtxrun --script fonts --reload: mtxrun | the resolver databases are not present or outdated mtxrun | unknown script 'fonts.lua' or 'mtx-fonts.lua' Please, what is to be done? Best wishes, Rudolf

macro that does not work (Metapost)
by Fabrice Couvreur 11 Feb '20

Hi, I have some problems with the following macro : tex error > mp error on line 23 in file /home/viserion/macro.tex: ! Missing argument to suite. <to be read again> { <*> suite{ 1,0}; suite(2,1); ; That macro has more parameters than you thought. I'll continue by pretending that each missing argument is either zero or null. ! Missing argument to suite. <to be read again> { <*> suite{ 1,0}; suite(2,1); ; That macro has more parameters than you thought. I'll continue by pretending that each missing argument is either zero or null. ! Extra tokens will be flushed. <to be read again> { <*> suite{ 1,0}; suite(2,1); ; I've just read as much of that statement as I could fathom, so a semicolon should have been next. It's very puzzling... but I'll try to get myself back together, by ignoring everything up to the next `;'. Please insert a semicolon now in front of anything that you don't want me to delete.
