I've seen the following solution in Stack Exchange to add referenceable enumeration labels to a framed enumeration environment: https://tex.stackexchange.com/questions/438588/context-and-metafun-framed-e… It uses \wrappedcurrentconstruction. However, it only prints the counter label and the counter name. What if I need the text enclosed by braces in the frame header too? E. g. \starttheorem[thm1]{Residue theorem} so the framed title includes "Residue theorem" also. Thank you in advance.

lmtx vs mkiv
by Hans Hagen 18 Apr '20

18 Apr '20

Hi, One problem of mixed usage of mkiv (with luatex) and lmtx (with luametatex) is that in the later we use a different (initial) context runner. Basically all platforms are now handled the same (in mkiv there was a stub and no texlua, in unix something shebang with texlua because of argument passing limitations). However, the main context script can be told to use a specific engine: context --luatex foo.tex so in principle one can use both lmtx and mkiv with the same binary tree, given that luametatex and luatex are both present and that luametatex is in charge. For that reason the latest lmtx installer now (for the time being) also includes the luatex binary (plus mkiv files needed) so that one can install lmtx and run both engines. Instead of the --luatex switch one can also force the engine in the usual way with "% engine=luatex" at the top line of the source file (but no pdftex and xetex in this installer). FWIW, the lmtx installation ships with the latest experimental luatex binary but normally that should not have consequences, but it does permits testing occasional updates.

Using two versions of ConTeXt
by Jairo A. del Rio 18 Apr '20

18 Apr '20

Hi everyone! I'm using the ConTeXt version packaged with TeX Live 2020 and recently I have downloaded LMTX. Both of them work, but when I call "context" from terminal, I compile with the TeX Live version, whereas I have to use a fully specified path to get LMTX output. Is there a way to call both from terminal, say, using "lmtx" or other shortcut for the standalone version? I work on Ubuntu 18.04. Thank you in advance.

"Remember picture" does not work (again)
by Jairo A. del Rio 18 Apr '20

18 Apr '20

I've tried using the fix in https://tex.stackexchange.com/a/492197/193767 in order to make TikX's remember picture feature usable, Code below, just in case: \unprotect% This fixes the present bug\unexpanded\def\pdflastxpos{\numexpr\clf_lastxpos\relax}\unexpanded\def\pdflastypos{\numexpr\clf_lastypos\relax}% This might be needed if you run PGF 3.1.3% see https://github.com/pgf-tikz/pgf/issues/675\def\XC@tgt@mod#1{#1}\def\XC@sdef… picture] \node (A) {Node 1};\stoptikzpicture Hi world\starttikzpicture[remember picture] \node (B) {Node 2};\stoptikzpicture\starttikzpicture[overlay,remember picture] \draw (B) --++(0,0.5) -| (A);\stoptikzpicture\stoptext However, the following appears: l.1 6 120806 \lastxpos ->\clf_lastxpos <write> \noexpand \pgfsyspdfmark {pgfid1}{\the \lastxpos }{\the \lastypos } <inserted text> }\endwrite <argument> \shipoutscratchbox \page_shipout_box #1->\clf_shipoutpage #1 \relax \setbox #1\emptybox \global ... ... l.20 \stoptext I use LuaTeX 1.10 7127 + ConTeXt MkIV 2019.03.21 21:39 (TeX Live version), in case this helps. Is another fix necessary? A Metapost alternative would be fine, too.

Colors in lmt_surface and luametafun
by Otared Kavian 17 Apr '20

17 Apr '20

Hi Hans, On page 36 of luametafun.pdf there is the following example of using lmt_surface: \startMPcode{doublefun} draw lmt_surface [ preamble = "local sin, cos = math.sin, math.cos", code = "sin(x*x) - cos(y*y)", color = "f, f/2, 1-f", color = "f, f, 0", xstep = .02, ystep = .02, xvector = {-0.4, -0.4}, height = 10cm, lines = true, ] xsized .TextWidth ; \stopMPcode What is the meaning of « f » in « color = "f, f/5, 1-f" »? Is it possible to specify other colors and how can it be done? Thanks for your attention: Otared

\startMPcode and \startMPpage
by Jeong Dal 17 Apr '20

17 Apr '20

Hi, The following sample code is working well in the \startMPpage ~ \stopMPpage, but is not working in the \startMPcode ~ \stopMPcode. The error message is \textfont0 is undefined (character 63) l.6 \setstrut\strut $A$ If I remove “$” from the code, it is also working in \startMPcode ~ \stopMPcode. Is there anything which I have to set for \startMPcode? Best regards, Dalyoung %%%%%%%% \startMPcode{doublefun} %\startMPpage numeric count, temp[], tt, minus, u; u := 1cm; path p,q,r; pair A,B,C,D; string varName, ss, pos[]; p := unitsquare xyscaled (8u,3.5u); draw p; pos[0] := "bot"; pos[1] := "rt"; pos[2] := "top"; pos[3] := "lft"; varName := "yxwz"; count := 0; pickup pencircle scaled 5pt; for i = 0 upto 3: drawdot (point i of p); draw lmt_text[ text = "$" & char(65+i) & "$", anchor = pos[i], offset = 2pt, position = point i of p, ]; endfor; %\stopMPpage \stopMPcode

filtering pages from /PrintPageRange
by Pablo Rodriguez 17 Apr '20

17 Apr '20

Dear list, this is a new experience deep inside LuaMetaTeX (for me). I need to compose a new document from selected pages (which are marked automatically and stored in /PrintPageRange) in a PDF document containing 1000 pages. It has to be one of the worst coding snippets ever written, but it works. It reads the array from /PrintPageRange, deploying it in context.filterpages. \startluacode function document.printrange_from_file(filename) range_array = pdfe.open(filename).Catalog.ViewerPreferences.PrintPageRange for i=1,#range_array do file_page = range_array[i] if file_pagerange == nil then file_pagerange = file_page else file_pagerange = file_pagerange .. " " .. file_page end end for str in file_pagerange:gmatch("([^%s]+)") do add_one = str + 1 if right_range == nil then right_range = add_one else right_range = right_range .. " " .. add_one end end spaces_in_pagerange = right_range:find(' ') local _, spaces_in_pagerange = right_range:gsub(" ", "") for actualspace=1,spaces_in_pagerange do if (actualspace % 2 == 0) then right_range = right_range:gsub(' ',',', 1) else right_range = right_range:gsub(' ',':', 1) end end context.filterpages( { filename }, { right_range }, { width = Opt } ) end \stopluacode \def\filterfrompagerange[#1]{% \ctxlua{document.printrange_from_file("#1")}} \setuplayout[page] \setupinteractionscreen[option={portrait, paper}] \starttext \filterfrompagerange[huge-book.pdf] \stoptext I copied and adapted all from Stackoverflow snippets. It is useful for me, since it file will be changing, page marking is automatic and filtering marked pages will be automatic too. But I wonder whether this may be useful to others. I wonder whether it makes sense to add it to the wiki. Let me know what you think about -- http://www.ousia.tk
