issue with \in and \xmlrefatt
by Pablo Rodriguez 13 Mar '21

13 Mar '21

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. Many thanks for your help, Pablo -- http://www.ousia.tk

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

Escaping reserved/problematic characters
by Benct Philip Jonsson 11 Mar '21

11 Mar '21

In a program I'm writing I have a function for escaping characters which are reserved or problematic in LaTeX. I would like to have a corresponding function for ConTeXt, so I'm wondering which ones are different/superfluous/missing from a ConTeXt perspective in the following list (sorry about the formatting!): '{': "\\{" '}': "\\}" '_': "\\_" '%': "\\%" '#': "\\#" '$': "\\$" '&': "\\&" '`': "\\textasciigrave{}" '^': "\\textasciicircum{}" '~': "\\textasciitilde{}" '\\': "\\textbackslash{}" '|': "\\textbar{}" '<': "\\textless{}" '>': "\\textgreater{}" '[': '{[}' ']': '{]}' Note that I'm not looking for accented letters, Unicode quotes and dashes etc. I'm assuming that people in the year 2021 are using an UTF-8-aware engine (and my corresponding HTML escape function similarly caters only to & < > " '). TIA, /Benct

\underbar and co. not working properly in MkIV
by Jairo A. del Rio 10 Mar '21

10 Mar '21

Hi, list. The following works well in LMTX, but it applies underlining to the next dash sign when compiled with MkIV: \starttext %\overbar{foo}-bar \underbar{foo}-bar \stoptext I've found a workaround for it, but I want to know about the reason for such a strange behavior. Thanks beforehand. Best regards, Jairo

Hi, when the wildcard symbol is used as argument to \startcomponent (or \startproduct) the name of the folder is now used and not the file name. \startcomponent * \quotation{\currentcomponent} \stopcomponent Wolfgang

bug in lmtx
by Thomas A. Schmitz 10 Mar '21

10 Mar '21

Hi Hans, I've found a very interesting bug in lmtx. The following MWE gives the expected result in mkiv; in lmtx, one character is missing. Perhaps you can figure out what's happening... All best Thomas \setupbodyfont [gentium, 12pt] \starttext Test \hskip1em ἀβ Test \hskip1em ἁβ \stoptext
