Possible problem with context using the ARM 64bit download for Apple Silicon M1
by Keith McKay 23 Feb '21

23 Feb '21

Hi all I have been using ConTeXt (X86 64bits) on my mac mini Apple Silicon M1 and it works well using Rosetta translation for the M1. I recently installed the ARM 64bits version (separately from the X86 64bits version) which I assume does not require translation using Rosetta. However I had a error with the lmt_shade command in the ARM 64bits ConTeXt verson but not in with the X86 64bits version of ConTeXt. The MWE is shown below. This is actually taken from the LuaMetaFun manual. I also noticed that some figures are missing in the manual (Chapter 7, Shade) which is part of the ARM 64bit tree but not in the manual in the X86 64bits tree. Best Wishes Keith McKay Hamilton, Scotland. %%%%%%%%%%%%%%%%%%%%%%%%% \setuppapersize [A4, portrait] \usecolors[crayola] \starttext \startMPpage StartPage; width := PaperWidth ; height := PaperHeight ; unit := cm ; definecolor [ name = "MyColor3", r = 0.22, g = 0.44, b = 0.66 ] ; definecolor [ name = "MyColor4", r = 0.66, g = 0.44, b = 0.22 ] ; draw lmt_shade [ path = fullcircle scaled 4cm, direction = "right", domain = { 0, 2 }, colors = { "MyColor3", "MyColor4" }, ] ; StopPage; \stopMPpage \stoptext %%%%%%%%%%%%%%%%%%%%%%%% Here is the error taken from the log <snip> system > system > ConTeXt ver: 2021.02.20 16:50 LMTX fmt: 2021.2.21 int: english/english system > system > 'cont-new.mkxl' loaded <snip> metapost > initializing number mode 'scaled' metafun > log > metafun > log > error: Not a cycle metafun > log > metapost > log > <to be read again> metapost > log > withprescript metapost > log > <argument> ...asparameter"vector":center_a:=point(getparameter"vector"1)of.mfun_shade_path;center_b:=point(getparameter"vector"2)of.mfun_shade_path;fi.fill.mfun_shade_path.withprescript metapost > log > "sh_domain="... metapost > log > image->begingroup.save.currentpicture;picture.currentpicture;currentpicture:=nullpicture;(TEXT3) metapost > log > ;currentpicture.if.str(SUFFIX2)<>"":shifted(mfun_labxf(SUFFIX2)*lrcorner.p+mfun_labyf(SUFFIX2)*ulcorn... metapost > log > lmt_do_shade->...ve="circular":draw.fullcircle.scaled(radius_a)shifted.center_a.dashed.evenly;draw.fullcircle.scaled(factor*radius_b)shifted-center_b.dashed.evenly;fi.fi.popparameters;) metapost > log > endgroup metapost > log > <scantokens> lmt_do_shade metapost > log > metapost > log > <*> ... name = "MyColor4", r = 0.66, g = 0.44, b = 0.22 ] ; draw lmt_shade [ path = fullcircle scaled 4cm, direction = "right", domain = { 0, 2 }, colors = { "MyColor3", "MyColor4" }, ] metafun > log > metafun > log > That contour should have ended with '.. cycle' or '& cycle'.

Arbitrary equation tags... again
by Jairo A. del Rio 23 Feb '21

23 Feb '21

Hi. list. Is it possible to assign an arbitrary equation tag in ConTeXt? I've seen solutions here; https://tex.stackexchange.com/questions/400257/tag-equation-in-context-with… but none of them works as expected (either the formula counter is still incrementing with arbitrary conversions or cross-references don't work). I imagine some things have changed in 2021 and I hope a better solution is feasible nowadays. Best regards, Jairo

[LMTX] fonts problem (again)
by kaddour kardio 23 Feb '21

23 Feb '21

Hi! Once again i'm unable to load my system's font which is working well with MKIV. i have followed the steps : export OSFONTDIR=~/.local/share/fonts:/usr/share/fonts:/usr/share/texmf/fonts/opentype/ mtxrun --generate mtx run --make mtxrun --script fonts --reload without success. This problem occurred to me since december 2020, i update LMTX weekly from the archlinux user repo (aur) binary. Any suggestions? -- Dr YAHYAOUI Mohamed Kaddour, cardiologue .

lmtx error: You can't use 'integer 340' in internal vertical mode
by juh 23 Feb '21

Hi, I can't yet provide a mwe as the project is quite complex and includes color profiles and bleed. I can process it with context. When I process it using lmtx but without colorprofiles and bleed, it works. When I process it using lmtx with colorprofiles and bleed, it get this error: tex error > tex error on line 1 in file ./prod-poster-motiv-souveraenitaet.tex: You can't use 'integer 340' in internal vertical mode <macro> \page_shipouts_arrange ...setbox \shipoutscratchbox \hpack {\getobject \??arrangedpage {\the \realpageno }}\fi \pusharrangedpage \shipoutscratchbox \deadcycles \zerocount \endgroup <macro> \page_boxes_shipout ...tbox \shipoutscratchbox \hpack {#1}\page_shipouts_handle {\finalizeshipoutbox \shipoutscratchbox \box \shipoutscratchbox } \fi \setnextrealpageno \the \everyaftershipout \ifcase \c_page_boxes_flush_n \else \page_boxes_flush_after \fi <macro> \page_otr_construct_and_shipout #1#2#3->\forgetall \page_boxes_shipout {\page_boxes_constructed_page #1#2} \page_otr_flush_pending_content \page_otr_check_for_pending_inserts \inpagebodytrue \pagebodymode \plusone \page_otr_command_flush_saved_floats \page_otr_command_set_vsize \str <macro> \currentcolorname \page_otr_command_side_float_output \ifconditional \c_page_sides_short \global \setfalse \c_page_sides_short \else \global \d_page_sides_vsize \d_page_sides_vsize_reset \global \c_page_sides_n_of_lines \zerocount \fi <macro> \currentcolorname \ifcsname \??otrtriggers \the \outputpenalty \endcsname \lastnamedcs \else \page_otr_command_routine \fi <output> {\inotrtrue \the \everybeforeoutput \page_otr_triggered_output_routine \relax \the \everyafteroutput } ... <line 3.47> \stopproduct Are there changes with modes or setupbackend in lmtx?

Using Gill Sans on macOS
by Gerben Wierda 22 Feb '21

22 Feb '21

I’m normall using Optima Nova on my system, e.g. by defining a font like this: \definefontfamily [archimate] [ss] [Optima nova LT Pro] [tf=style:Medium, bf=style:Bold, it=style:Medium Italic, bi=style:Bold Italic] \setupbodyfont[archimate] I would like to experiment with Gill Sans, but that fails with fonts > defining > unable to define 'GillSans.ttc' as 'archimate-14pt-ss-tf-0--0' It is here: /System/Library/Fonts/Supplemental/GillSans.ttc What should I do to be able to use that font?

path in LuaMetaFun
by Pablo Rodriguez 21 Feb '21

21 Feb '21

Dear list, I have the fowllowing sample: \starttext \startmakeup[page][align=middle] \startMPcode{doublefun} draw lmt_followtext [ text = "\feature[+][smallcaps]\bf\samplefile{zapf} ", path = ((0,0)..(3,3.25)..(9,-3.25)..(12,0)..(9,3.25)..(3,-3.25)..(0,0)), autoscaleup = "max", reverse=true, ] xsized .75TextWidth ; \stopMPcode \startMPcode{doublefun} draw lmt_followtext [ text = "\feature[+][smallcaps]\bf\samplefile{zapf} ", path = ((0,0)..(3,3.25)..(9,-3.25)..(12,0)..(9,3.25)..(3,-3.25)..cycle), autoscaleup = "max", reverse=true, ] xsized .75TextWidth ; \stopMPcode \stopmakeup \stoptext I’m afraid I don’t understand how to close the path. Cycle has problems with part of the text and returning to the start seems to distort the path itself. Which is the right way to close the path or what am I missing? Many thanks for your help, Pablo -- http://www.ousia.tk

metafun
by Hans Hagen 20 Feb '21

20 Feb '21

Hi, When making sure that the metafun manual processes with lmtx (where we have sometimes different implementations of macros) I also checked performance. When we started with this manual, it was still MKII time so we either had direct calls or inbetween calls. Especially multiple runs could take a while (many minutes, iir some 15 depending on how it was run). That was no fun. In mkiv with luatex and the built in mp library this dramatically went down to 18.1 seconds for one run and 14.2 seconds for luajittex, for 428 pages. This not bad considering that a lots of features are used: thousands of mp images, a bunch of external images, many fonts, plenty of buffers, positioning, color, hyperlinks, backgrounds etc. This document uses plenty of lua so that is why we gain a lot with luajittex. In lmtx where we dropped jit and have a less performing backend we expect to need more runtime but in the meantime we're quite okay. Not only the engine is faster, but also some low level macros benefit a bit from new features. I don't know how much lua speedup plays a role but probably not that much. For 448 pages (some 20 more than we had before) we now need 16.5 seconds and 15.7 when we use the compact font mode. So we're halfway between luatex and luajittex now. More than 3 seconds of the runtime is for metapost. (I use the machine as before.) Hans PS. If all the stories are true is should be 1 second on a modern apple at which point differences in measurements become noise but I cannot check that. Some day I might check it on a rpi 4. ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
