(huge thanks) attaching files from links
by Pablo Rodriguez 04 Mar '19

04 Mar '19

Dear list, I was about to ask how to attach a file from links and I just discovered that it works perfectly fine. \attachment[http://pragma-ade.com/general/manuals/xtables-mkiv.pdf] I just wanted to thank Hans and all developers for the awesome work with ConTeXt and LuaTeX. They are outstanding pieces of code. Sorry for not expressing this clearer and more often. Many thanks again for your work and your help, Pablo PS: I wonder whether ConTeXt/LuaTeX might do my laundry, the dishes, home cleaning or cooking... 😊. -- http://www.ousia.tk

LuaTex on Windows PCs
by Nigel King 04 Mar '19

04 Mar '19

Hi All, I have been using ConTeXt on Macs for >20 years. Having written a particular piece of code for others to operate who have PCs, I am now stuck. I upgraded to LuaTeX some time ago as recommended on this list. IT do not seem to be able to install a working version of LuaTeX on PCs. I have directed them to ConTeXt Garden but they have had no luck. Do any of you have guaranteed pointers to a simple installation on PCs? Simple editing and creating (from ConTeXt) the PDFs is all that is required. Thanks — Nigel nigel(a)nigelking.me.uk m:07917 803879

util-sha.lua misbehaving?
by Pablo Rodriguez 04 Mar '19

04 Mar '19

Dear list, I have the following sample: \startluacode function document.capture(cmd, raw) local f = assert(io.popen(cmd, 'r')) local s = assert(f:read('*a')) f:close() if raw then return s end s = string.gsub(s, '^%s+', '') s = string.gsub(s, '%s+$', '') s = string.gsub(s, '[\n\r]+', ' ') return s end function document.sha512(file) command_output= document.capture("sha512sum -b " .. file) context(command_output:sub(0,8)) end \stopluacode \def\shafive#1{\ctxlua{document.sha512("#1")}} \doif{\luaversion}{5.3}{\ctxlua{require("util-sha")}} \def\hashfive#1{% \ctxlua{context( utilities.sha2.hash512("#1"):sub(0,8))}} \def\hashfivefile#1{% \ctxlua{context( utilities.sha2.hash512(io.loaddata("#1")):sub(0,8))}} \def\cB{i-context.pdf} \starttext \startTEXpage[offset=2em] \tt i-context.pdf\ss: \doifelse{\luaversion}{5.3} {\hashfivefile{\cB}\\ {\rm text: }\hashfive{\cB}} {\shafive{\cB}} \stopTEXpage \stoptext Just accidentally, I discovered today (using latest beta from 2019.02.26 20:04) that file hashing may be wrong in ConTeXt. For the sake of brevity, I only use the 8 first chars. "sha512sum i-context.pdf" gives c4cc3840. Using luajittex, I get that result. But using Lua 5.3 (and util-sha.lua), I get 44241e9d. I don’t know whether my invocation of io.loaddata is wrong, since the SHA512 for the text "i-context.pdf" is 2ac2778b, which is the same result as https://duckduckgo.com/?q=sha512+i-context.pdf. After discovering that io.loaddata is from l-io.lua, I don’t know what I may be doing wrong. This is an essential feature for me in ConTeXt, since it is the way of showing the integrity of the attached files to a PDF document (mainly digitally signed documents). Could anyone tell me what I am missing here? Many thanks for your help, Pablo -- http://www.ousia.tk

ARIAL and hebrew
by Willi Egger 04 Mar '19

04 Mar '19

Good evening! I have a little project for preparing a vocabulary for an Ivrith student. — The text should be typeset with Arial. However, when I try to use it I get the vowel points between the glyphs instead of thereunder. — So my question is, does anybody have experience with the use of Arial for typesetting Hebrew? Kinde regards Willi

textext within ConTeXt
by Mohammad Hossein Bateni 03 Mar '19

03 Mar '19

Hi, I can't understand why the following code does not work. Could someone help me out here? \starttext \startMPpage draw textext("\convertnumber{r}{12}"); draw textext("\convertnumber{r}{" & "12" & "}"); \stopMPpage \stoptext The first draw statement works perfectly. But the second one throws out errors and complains as follows: .....test.tex: ! Missing number, treated as zero <to be read again> <argument> \number " & "12" & " \romannumerals #1->\clf_romannumerals \numexpr #1 \relax <argument> ... draw textext("\convertnumber {r}{" & "12" & "} "); \meta_process_graphic ...currentMPformat }data {#1 ;}initializations {\meta_f... \page_fitting_stop_command ...eter \c!command {#1} \page_fitting_stop_normal Is there a workaround here? Ultimately I want to replace "12" with a loop variable in MetaPost. Thanks, ~MHB

Space between initials in bibliography
by Mikael P. Sundqvist 03 Mar '19

03 Mar '19

Hi, By default there seem to be no space between initials in bibliography (which I guess there should be?). I can get a space by adding \setupbtx[ stopper:initials={.\btxspace}, ] but I don't think that this is how the stopper is meant to be used. Do I miss some other key that I can use to get space inbetween initials? Minimal example below, and I attach the result without the setting above (no space V.I. Arnol'd) and with the setting above (space V. I. Arnol'd). /Mikael %Example \startbuffer[ref] @book {arnold, AUTHOR = {Arnold, Vladimir I.}, TITLE = {Ordinary differential equations}, SERIES = {Universitext}, NOTE = {Translated from the Russian by Roger Cooke, Second printing of the 1992 edition}, PUBLISHER = {Springer-Verlag, Berlin}, YEAR = {2006}, PAGES = {ii+334}, ISBN = {978-3-540-34563-3; 3-540-34563-9}, MRCLASS = {34-01 (34Cxx 37-01 37C10)}, MRNUMBER = {2242407}, } \stopbuffer \usebtxdataset[ref][ref.buffer] \setupbtx[dataset=ref] \definebtxrendering[ref][dataset=ref] \setupbtx[ stopper:initials={.\btxspace},%comment to show version without space ] \starttext \startTEXpage[offset=3bp] We study \cite[arnold]. \placelistofpublications[ref][method=dataset] \stopTEXpage \stoptext
