getnonfreefonts with LMTX
by Philipp A. 14 Mar '21

14 Mar '21

Hi! The LMTX distribution comes with few binaries, texlua being none of them. The getnonfreefonts <https://www.tug.org/fonts/getnonfreefonts/> script seems simple enough, but it relies on a global “kpse” which it uses to get kpse variables. Therefore luametatex --luaonly can’t execute it. Is there a way to get those fonts with the standalone LMTX distribution? Best, Phil

missing "{ }" in metafun.
by Jeong Dal 14 Mar '21

Hi, Set notation “{}” is OK in TeX mode. But it is missing in the output of the metafun code. Here is an MWE. It is same in two different versions. ConTeXt ver: 2021.01.17 21:42 LMTX fmt: 2021.2.4 int: english/english ConTeXt ver: 2021.03.13 11:22 LMTX fmt: 2021.3.14 int: english/english \startbuffer[test] label(textext("$\{a,b\}$"),origin); \stopbuffer \starttext Let $A = \{a,b\}$. \processMPbuffer[test] \stoptext Thanks. Best regards, Dalyoung

tlig feature sometimes does not work
by Mohammad Hossein Bateni 14 Mar '21

14 Mar '21

Hi, Since most fonts do not have the standard tex ligatures built in, I tend to add them when I load the fonts. Once in a while, I run into fonts where this does not work. See the attached tex/pdf files. I basically load the font as follows: \definefontfeature[tf][arabic][tlig=yes] \definedfont[dejavusansmono*tf] This works fine for DejaVuSansMono and for one Farsi font I use ( https://github.com/rastikerdar/vazir-font/blob/master/dist/Vazir-Regular.ttf) but not for this other Farsi font ( https://github.com/aminabedi68/Mikhak/blob/master/Font/ttf/Mikhak-Medium.ttf) Perhaps this is because the last font is not standard, but TrueType/OpenType standard is sometimes up for interpretation. I see two strange symptoms here: \showotfcomposition displays the tlig feature differently for the last font. It appears in the "extra" list, not in "basic". Why is that? What does this mean anyway? In the pdf, you see two unicode characters U+647 and U+654 following the numbers and dashes. This usually has a ligature turning the two characters into U+6C0. It happens for VazirRegular but not for Mikhak-Medium. Why is that? I have looked in the font: the ligature exists. I have seen that working in this demo page (https://aminabedi68.github.io/Mikhak/) though it may be hard to spot. Why is that? Is there something about the ordering of OpenType features which causes this behavior, or is there a bug in the font processing code? Best, MHB

Hans, after the fix in current latest (2021.03.09 11:42), I get the following error when using \in[\xmlrefatt{#1}{href}] in Windows (Linux has no problems). The error message reads: fatal lua error: run callback [6]: bad argument #2 to 'format' (number expected, got nil) stack traceback: [C]: in function 'string.format' ?: in field '?' ...ext/tex/texmf-context/tex/context/base/mkxl/luat-log.lmt:178: in upvalue 'report' ...ext/tex/texmf-context/tex/context/base/mkxl/luat-log.lmt:391: in upvalue 'report' [string "<m:/context/tex/texmf-context/tex/c..."]:2999: in field '?' ...ext/tex/texmf-context/tex/context/base/mkiv/luat-run.lua:56: in function <...ext/tex/texmf-context/tex/context/base/mkiv/luat-run.lua:54> mtx-context | fatal error: return code: 1 I cannot provide a minimal sample and I wonder whether this could be enough to find out what is missing.

margin in TocEntry definition
by jbf 12 Mar '21

12 Mar '21

Hi list, I have: \define[1]\SectionTocEntry{% #1\crlf% title \doifnot{\structurelistuservariable{author}}{}{\structurelistuservariable{author}}% } which successfully gives me a ToC with: Chapter title Author name But I want the author name indented by .5cm and do not know how to use 'margin' in the above definition, or some other way of getting the indentation. I have tried various versions of 'margin' before the \doifnot part of the definition, but to no avail. Hopefully I can achieve: Chapter title Author name Julian

lmt_outline
by Mohammad Hossein Bateni 12 Mar '21

12 Mar '21

Hello, Hans said he's in the metapost mode now :) I have used lmt_outline in the following example and it is really an improvement over the previous outline "effect" because one can set the fillcolor and drawcolor separately. (that was not possible before, right?) \starttext \definedfont[dejavusansmono*arabic] \setupalign[r2l] \startMPcode draw lmt_outline [ text = "سلام", drawcolor = "red", fillcolor = "white", kind = "reverse", align = "r2l", ] scaled 3mm; \stopMPcode \stoptext 1. This works well on a plain background. I can specify the background color in fillcolor and get the outline effect. When the background is an image, this does not work too well. Can we use some clip trickery to allow for "transparent" fill? Ideally I want to set the fillcolor to a special value that would lead to only the outlines drawn. Now you'd say, that was already available via the outline "effect" before. Not quite. If a character is formed by more than one curve in the font, then we'd see some lines drawn inside the character. The new lmt_outline mechanism allows one to paint over those. Which brings me to the next problem. 2. The current mechanism draws/fills the characters one by one. In Farsi/Arabic where we have joint characters, the boundaries of letters gets drawn even in the new mechanism. See the attached PDF of the above MWE. The text consists of four characters, the 2nd and 3rd form a ligature which is joined to the 1st character. The 4th char is not joined and stands alone. Now you see the red connection between the 1st char and the ligature following it. It would be nice if the text was allowed to be processed as a whole (or at least be broken into space delimited pieces) which is drawn and then filled. Thanks, MHB
