Bug inline math in lmtx
by Otared Kavian 15 Dec '19

15 Dec '19

Hi Hans, It seems that the bug which was reported recently is again there: inline math does not show some symbols (lmtx version 2019.12.12 19:35). However mkiv version 2019.12.12 19:23 MKIV beta fmt: 2019.12.14 works fine. Here is a minimal example. \starttext Let $f(x) := \sum_{n \geq 1}2^{-n}x^n$. \stoptext Best regards: OK

Dear Otared, > I updated the wiki page for installing LuaMetaTeX on MacOS: > > https://wiki.contextgarden.net/installing_luametatex Thank you for the wiki. It explains the complicate processes well. As I wrote in the last mail, I don’t have a problem of installation as before. At this time, I don’t need to change SIP and the options of Gatekeeper in Mac OSX Catalina. Since I downloaded “install.sh”, it is inexecutable at the first time. But it worked well after allowing its running in the preference>security tab once. I don’t know why there is no problem at all as before. There may be some changes in the new beta. For test, I installed the new beta once more and confirmed that it is installed well and running well. However, your description is very useful when “install.sh” needs a permission of execution again and again. Thank you for your helpful advice again. Best regards, Dalyoung

Dear Hans, I downloaded the new beta today. It installs files and makes format file well. I compiled a test file without any problem. Of course, there is a security issue of OSX, but allowing the execution in the preference>security once, it doesn't ask about again. I also run a test file containing a new graphic feature of LMTX and I got a nice output. Thanks!!! Best regards, Dalyoung P.S. Here is a beginning part of log file. I installed new beta in the folder /Users/graph/ConTeXtC/ %%%%%%%%%%%%%%% resolvers | formats | executing runner 'run luametatex format': /Users/graph/ConTeXtC/tex/texmf-osx-64/bin/luametatex --jobname="test" --fmt=/Users/graph/ConTeXtC/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/luametatex/cont-en.fmt --lua=/Users/graph/ConTeXtC/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/luametatex/cont-en.lui cont-yes.mkiv --c:autopdf --c:currentrun=1 --c:fulljobname="/Users/graph/ConTeXtC/test.tex" --c:input="/Users/graph/ConTeXtC/test.tex" --c:kindofrun=1 --c:maxnofruns=9 --c:purgeall --c:texmfbinpath="/Users/graph/ConTeXtC/tex/texmf-osx-64/bin" This is LuaMetaTeX, Version 2.03.3 open source > level 1, order 1, name 'cont-yes.mkiv' system > system > ConTeXt ver: 2019.12.06 21:40 MKIV beta fmt: 2019.12.12 int: english/english system >

lmtx
by Hans Hagen 12 Dec '19

12 Dec '19

Hi, The last few days there have been reports about garbled files in the lmtx installation so I did some test oinon a linux machine and indeed there was some issue (I'm not sure what causes it). Anyway, I made new zips so maybe one needs to reinstall (using the installer zip). It installs okay on wsl so probably also on other linuxes. This version (luametatex 2.03.3) has (again) a little smaller mem footprint as I still want it all to perforem ok on relative small devices or vm's and as side effect a bit smaller format file, not that that matters much (compared to general mem usage). There is not much to gain anyway, in terms of memory usage and performance so it's more an occasional challenge than a neccessity I guess. Anyway, hopefully nothing got broken. Peter Rolf and I are updating some of the pdf validation related stuff (additional formats), so that can be in flux.

Using lmtx and new metafun
by Otared Kavian 12 Dec '19

12 Dec '19

Hi Aditya, Following your explanations in https://adityam.github.io/context-blog/post/new-metafun-interface/ I wrote an environment in order to display the graph of a function on a grid which can be adapted to each case. Assuming that I have an MPinstance named GridAxis (for example) which can dispaly a grid and axes, how can I call it and write a line such as draw function (1,"x","x*x/4 - 2.5",xmin,xmax,.001) scaled sx ; without changing the part whichh is included in \startMPdefinitions, in oder to draw the above function on that grid ? Thanks for your help: Otared PS: Here is my definition of GridAxis (I guess many parts of it could be better written…) \defineMPinstance[GridAxis] [ format=metafun, extensions=yes, initializations=yes, method=double, ] \startMPdefinitions{GridAxis} def GridAxisPlot = applyparameters "GridAxisPlot" "do_GridAxisPlot" enddef ; presetparameters "GridAxisPlot" [ xmin = -2.5, xmax = 2.5, ymin = -2.5, ymax = 2.5, dx = 1, dy = 1, sx = 5mm, sy = 5mm, scale = 0.5, grid = true, xaxisnumbers = true, yaxisnumbers = true, showmyorigin = true, style = "\switchtobodyfont[8pt]", ]; vardef do_GridAxisPlot = image ( pushparameters "GridAxisPlot"; newnumeric xmin, xmax, ymin, ymax; xmin := getparameter "xmin"; xmax := getparameter "xmax"; ymin := getparameter "ymin"; ymax := getparameter "ymax"; newnumeric sx, sy; sx := getparameter "sx"; sy := getparameter "sy"; newnumeric dx, dy; dx := getparameter "dx"; dy := getparameter "dy"; newpath xaxis, yaxis; xaxis := (xmin*sx, 0) -- (xmax*sx, 0) ; yaxis := (0, ymin*sy) -- (0, ymax*sy) ; newpath xtick, ytick; xtick := (-0.1sx, 0) -- (0.1sx, 0); ytick := (0, -0.1sy) -- (0, 0.1sy); newstring style; style := getparameter "style"; pickup pencircle scaled .1mm ; newboolean grid; grid := getparameter "grid"; newboolean xaxisnumbers ; xaxisnumbers := getparameter "xaxisnumbers" ; newboolean yaxisnumbers ; yaxisnumbers := getparameter "yaxisnumbers" ; for x = dx step dx until xmax : if grid : draw yaxis shifted (x*sx, 0) withcolor 0.75white ; fi draw ytick shifted (x*sx, 0); if xaxisnumbers : label.bot(style & decimal x, (x*sx, 0)); fi endfor newboolean showmyorigin ; showmyorigin := getparameter "showmyorigin" ; if showmyorigin : label.lrt(style & "0", origin) ; fi for x = -dx step -dx until xmin : if grid : draw yaxis shifted (x*sx, 0) withcolor 0.75white; fi draw ytick shifted (x*sx, 0); if xaxisnumbers : label.bot(style & decimal x, (x*sx, 0)); fi endfor for y = dy step dy until ymax : if grid : draw xaxis shifted (0, y*sy) withcolor 0.75white; fi draw xtick shifted (0, y*sy); if yaxisnumbers : label.lft(style & decimal y, (0, y*sy)); fi endfor for y = -dy step -dy until ymin : if grid : draw xaxis shifted (0, y*sy) withcolor 0.75white; fi draw xtick shifted (0, y*sy); if yaxisnumbers : label.lft(style & decimal y, (0, y*sy)); fi endfor drawarrow xaxis; drawarrow yaxis; label.rt( style & "$x$", (xmax*sx, 0)); label.top(style & "$y$", (0, ymax*sy)); newpair p ; newnumeric scale; scale := getparameter "scale" ; popparameters; ) enddef; \stopMPdefinitions

Ebooks with ConTeXt?
by Nicola 11 Dec '19

11 Dec '19

What is the current status of epub support in ConTeXt? I have never followed ConTeXt's development on the XML front too closely, but recently I have been asked to help format a text-only manuscript for publishing on platforms such as Kindle or Apple Books Store. Can ConTeXt be used (or perhaps even recommended) for that? Or would I have better luck with the proprietary tools (Kindle Create, iBooks Author)? Nicola

Bug: Segmentation fault
by Henri Menke 11 Dec '19

Dear devs, The example below crashes LuaTeX with a segmentation fault. It is reproducible with LuaTeX 1.10.1 7143 and LuaTeX 1.11.2 7226. To this end I built 7226 from source with --debugopt to get a backtrace, which can be found below as well.
