Question about text offset
by Henri Menke 28 Feb '18

28 Feb '18

Dear list, I was wondering, why is the text in the main text block offset by .25\exheight from above (and below)? Also, can you point me to the source line where this offset is added in shipout because it is not there in \setuplayout. If you don't know what I mean, see MWE below. Cheers, Henri --- \definelayer [pagebg] [width=\textwidth, height=\textheight] \setupbackgrounds [text][background=pagebg] \showframe \starttext \setlayer [pagebg] [voffset=.25\exheight] % why? {\vbox{\strut\input lorem\par}} \input lorem\par \stoptext

A small detail: The ISO specification for PDF 2.0 also defines the first page in /PrintPageRange to be page number 1 (not 0). :( Cheers, Christoph

How to use fonts.handlers.otf.enhancers.patches?
by Henri Menke 27 Feb '18

27 Feb '18

Dear list, The EB Garamond font is lacking the ϵ glyph but it contains ε. So naturally you want to remap ϵ to ε. It cannot be done using font features because the the slot 0x03B5 (ϵ) is just missing, so substitution will not kick in. I tried adapting the mechanism to add uppercase greek to Latin Modern Math from lm- math.lfg. Unfortunately, my code is not working. What am I doing wrong? Cheers, Henri --- \startluacode local patches = fonts.handlers.otf.enhancers.patches local function patch(data,filename) local uni_to_ind = data.map.map if not uni_to_ind[0x3F5] then patches.report("add ε for ϵ") uni_to_ind[0x3F5] = uni_to_ind[0x3B5] end end patches.register("after","missing glyphs","^ebgaramond*", patch) \stopluacode \setupbodyfont[ebgaramond] \starttext ε % = 03B5 ϵ % = 03F5 \stoptext

Re: [NTG-context] Problem with a macro

Dear Otared, All of your examples yield the same output in which the numbers locate at the top and at the bottom of the integral sign. Is it what you expected? I am looking for a way to place numbers at the right of the integral sign under the \startformula … \stopformula environment as the output of $\displaystyle\int_1^4 …$. I am using the latest beta. mtx-context | run 1: luatex --fmt="/Users/graph/ConTeXt/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/luatex/cont-en" --jobname="test" --lua="/Users/graph/ConTeXt/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/luatex/cont-en.lui" --no-parse-first-line --c:currentrun=1 --c:fulljobname="./test.tex" --c:input="./test.tex" --c:kindofrun=1 --c:maxnofruns=9 --c:purgeall "cont-yes.mkiv" This is LuaTeX, Version 1.05.0 (TeX Live 2017) system commands enabled. open source > level 1, order 1, name '/Users/graph/ConTeXt/tex/texmf-context/tex/context/base/mkiv/cont-yes.mkiv' system > system > ConTeXt ver: 2018.02.09 00:04 MKIV beta fmt: 2018.2.11 int: english/english system > Thank you.

typesetting information from git
by Schmitz Thomas A. 23 Feb '18

23 Feb '18

Hi, I like to add a sort of watermark with info about the git revision at the bottom of some files that I typeset. I’m using Lua, so I have: context(os.resultof("git --no-pager log --pretty='%h of %aD' -1 foo.xml”)) which gives something like "git revision b085c92a of Wed, 14 Feb 2018 12:49:35 +0100.” Suppose I want to make this more general. What would be the easiest way to either say “the xml file that is being processed” (something like arg[1]) or “the xml file whose name is in the Lua variable ‘foo?’” Thanks! Thomas

Problem with Lua: context.component()
by Procházka Lukáš Ing. 23 Feb '18

23 Feb '18

Hello, suppose having: ---- t1.mkiv \starttext a \startluacode context.setvalue("b", "bbb") context.setvalue("c", 2) context.component("t2.mkiv") \stopluacode \stoptext ---- and ---- t2.mkiv \startcomponent * \b\c \stopcomponent ---- I get no result when trying to compile t1.mkiv - log tells: " ... system > jobfiles > unknown tex file '{t2.mkiv}\stoptext \finishjob ' <<<<<<<<<<<<< ???????????? close source > level 1, order 3, name 'd:/Ctx-Beta/tex/texmf-context/tex/context/base/mkiv/cont-yes.mkiv' tex error > tex error on line 0 in file : ! Emergency stop <*> cont-yes.mkiv <empty file> *** (job aborted, no legal \end found) " So - how to use 'context.component()' (input a component within Lua) well? Thank you in advance.

show header text only on first page of chapter
by Henning Hraban Ramm 23 Feb '18

23 Feb '18

Hello again, in my current magazine layout I’m abusing the part structure as a rubric, i.e. the part title shows up only in the header and in the ToC. That works nicely so far, but I must show the rubric header only on the first page of a chapter (article). Which approach would you suggest? In my experience, it’s hard to find the right place for \setupheader(texts) so that it affects the right page(s).

Feature request: display Lua version
by Procházka Lukáš Ing. 22 Feb '18

Hello, namely due to planned embedding Lua 5.3 into ConTeXt, would it be possible ConTeXt to show Lua version being used? Something like: ---- d:\Lukas\ConTeXt\Test>context.exe --version mtx-context | ConTeXt Process Management 1.02 mtx-context | mtx-context | main context file: d:/Ctx-Beta/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2018.02.21 18:19 mtx-context | Lua version: 5.2.1 ---- Best regards, Lukas -- Ing.
