Modern CV like cover letter example
by Jonas Baggett 02 Dec '17

02 Dec '17

Hello everyone, As suggested by Wolfgang Schuster here : https://mailman.ntg.nl/pipermail/ntg-context/2016/087113.html , I have added on the wiki an example of a cover letter that has a similar style to Modern CV. You will find it here : http://wiki.contextgarden.net/Letter_style#Modern_CV_like_cover_letter . I hope it can help. Cheers, Jonas Baggett

Creating SVG: using MetaFun, exporting proper units, conversion to DXF
by Mojca Miklavec 27 Jul '17

27 Jul '17

Hi, I want to play with CNC and don't yet have any experience with CAD software (nor the licence for the expensive ones) other than perhaps some Blender, so I decided to try to use the super ugly route with metapost -> svg -> dxf -> g-code for the first time. I have a few questions. (1) I love Hans' shortcuts in metafun, but I seem to remember that things like input metafun; or perhaps input mp-tool; used to work, so that I don't have to remember to use mpost -mem=metafun my-drawings.mp when compiling the graphics. Did the method with "input" ever work (or is it supposed to work)? Now I'm getting a bunch of weird errors. I would love to specify everything in the source file and then just call mpost. If that doesn't work, that's fine, I can still add "-mem=metafun", but ... (2) I guess that using "raw metapost" is the only sane way to generate SVG. If I use metapost inside ConTeXt that's probably not going to work, right? (3) Is there any way to convince the SVG output mode to generate something like <svg ... width="100.0mm" height="100.0mm" ... > rather than <svg ... width="283.46456692913387" height="283.46456692913387" ... > because the program I use to convert SVG to DXF has troubles interpreting "points" properly. I read somewhere that they assume 90 points per inch because that's Inkskape's default. (4) Does anyone have a better proposal for conversion into DXF (or G-code)? I'm currently playing with FreeCAD and I've seen some tutorials showing that AutoCAD can open PDF directly, but I don't want to buy AudoCAD just for the sake of converting files. (Not to mention that FreeCAD's SVG importer crashes when reading output from MetaPost unless I manually remove parts of the SVG, but that's an unrelated problem that I'm somehow able to overcome.) Thank you, Mojca

Unicode text conversion
by Procházka Lukáš Ing. 16 Jun '17

16 Jun '17

Hello, does ConTeXt contain a built-in Lua conversion routine to convert text in UTF-16 (and others) to UTF-8 string? Something like: ---- \startluacode local str = "A unicode string" -- Or e.g. string loaded from a file str = convert(str, "utf16", "utf8") context(str) \stopuacode ---- TIA.

Character translation with Luaotfload
by Hans Åberg 13 Jun '17

13 Jun '17

Since Luaotfload is extracted from ConTeXt, I figure people here will know this: In the code below, math mode '.' and ',' are translated into ':'and ';', which seems to occur because that is what ASCII/Unicode has in those positions, unlike CMMI. So how to correct this? The issue is really trying to find get texinfo.tex working with Unicode fonts using LuaTeX, as it probably does not work with ConTeXt. (Later versions of the former use LuaTeX UTF-8 directly without translations.) ---- \input luaotfload.sty \font\stix={file:STIX-Regular.otf} at 10pt \font\stixit={name:STIXMath-Regular} at 10pt \font\stixsc={file:STIX-Regular.otf} at 7pt \font\stixscsc={file:STIX-Regular.otf} at 5pt \stix \textfont0=\stix \textfont1=\stixit % Translates ',' into ';'. \scriptfont0=\stixsc \scriptscriptfont0=\stixscsc \scriptfont1=\stixsc \scriptscriptfont1=\stixscsc \textfont2=\stix \textfont3=\stix Hello 𝑃, ±, $𝑥 = ±𝑦_𝑃$, $$𝑃_0, …, 𝑃_{𝑘 - 1} ⊢ 𝑃.$$ \end ----

Opentype features and space after comma in math mode
by Jose Luis Arellano 03 Jun '17

03 Jun '17

Hello list, Two questions: 1) How can i enable opentype features (onum, lnum, tnum) in math mode? 2) How can i avoid the space after comma in math mode? I tried this without success: \definefontfeature[default][default][onum=yes,lnum=no,tnum=no] \definefontfeature[lnum][default][onum=yes,lnum=no,tnum=no,mode=base] \definefontfamily[mainface][serif][TeX Gyre Pagella] \definefontfamily[mainface][math][TeX Gyre Pagella Math][features=lnum] \setupbodyfont[mainface] \starttext 1,123\par \m{1,123}\par \stoptext Thanks in advance...

mathmatrix and grid: followup
by Henri Menke 01 Jun '17

01 Jun '17

Dear list, some time ago I asked about the interplay of mathmatix with grid typesetting: https://mailman.ntg.nl/pipermail/ntg-context/2016/087018.html I noticed that when the grid is enabled, the height of a mathmatrix is rounded down which leaves less space above than below. In my opinion either the height should be rounded up or the depth rounded down here. In the original thread Wolfgang proposed using \setupformula[grid=tolerant] and adding a blank line before the formula (otherwise grid=tolerant is applied to the paragraph before). This workaround leads to the depth being rounded down in the example below which produces a more balanced output. Could this somehow be made the default behaviour or something? Currently it requires the user to notice that vertical spacing is off and correct it manually, including adding a blank line before the formula to prevent grid=tolerant being applied to the paragraph. Cheers, Henri --- \setuplayout[grid=yes] \showgrid \starttext \input knuth \startformula \vrule % make lineheight and depth visible \startmathmatrix \NC A \NR \NC B \NR \NC C \NR \stopmathmatrix \stopformula \input tufte \stoptext

For a while now, when I connect to contextgarden.net, I get redirected to wiki.contextgarden.net// (note the double slash). Is it just me, or something to be fixed in the web site? Nicola

(again) index sorting of accented characters
by Pablo Rodriguez 01 May '17

01 May '17

Dear list, sorry for bothering again with this issue, but I need to have indices in my documents. I have the following sample: \mainlanguage[es] \setupregister[method=default] \starttext \startTEXpage[offset=1em] \index{ámame}\index{arisco}\index{ándrago} \index{antonia}\index{antón} \placeindex \stopTEXpage \stoptext Word sorting is the following: antonia antón arisco ámame ándrago Right word order is: ámame ándrago antón antonia arisco In Spanish, as in other languages, an accented letter has no different sorting that its unaccented counterpart. I got the right word order adding these replacements in sort-lan.lua: replacements = { { "á", "a" }, { "é", "i"}, { "í", "i" }, { "ó", "o"}, { "ú", "u" }, { "ü", "u" }, }, Could anyone explain me whether this is the right way of doing it? I mean, if this is the way, I have other two patches for other two languages in which I have indices. And if I’m wrong, I would like to know how to get right word sorting in registers. Many thanks for your help, Pablo -- http://www.ousia.tk

High-level command for translated names
by Henri Menke 30 Apr '17

30 Apr '17

Dear list, Inspired by this question on TeX.SX https://tex.stackexchange.com/questions/367433 How can I get the translated names for chapter and section depending on the currently active language. I know they are there in lang-txt.lua, but cannot be accessed via \labeltext. One can access them through Lua but that doesn't seem so elegant. \def\chaptername{% \ctxlua{% context(languages.data.labels.texts.chapter.labels["\currentlanguage"])}} \starttext \language[en] \chaptername \language[de] \chaptername \stoptext Cheers, Henri
