Title in enumeration not working?
by Mikael Sundqvist 30 Dec '20

30 Dec '20

Hi, Has anything changed with titles and enumerations? I expected a title "Title" with the following setup. \defineenumeration[example][ text=Example, title=yes, ] \starttext \startexample[title={Title}] This is a test. \stopexample \stoptext But it does not show up. /Mikael

text alignment issue
by Alan Bowen 30 Dec '20

30 Dec '20

In the last few versions of luametatex standalone, paragraphs that were once justified now appear ragged right. My insertions of \setupparagraphs[align=wide/normal/yes] and \setupalign[wide/normal/yes] have had no effect. Is there some new coding that is needed to get justified text? Alan

Re: [NTG-context] adding url as a footnote in the caption of figure

Dear Pablo, Thank you for your reply. I just search wiki not the mailing list. I never used \setupnote before. > I would say that LMTX is causing an issue here (but for sure Hans knows > better). > > The issue with your MWE is solved by adding: > > \setupnote[footnote][width=\textwidth] It works fine. Thanks again. Best regards, Dalyoung

adding url as a footnote in the caption of figure
by Jeong Dal 29 Dec '20

29 Dec '20

Hi, I am trying to add a url as a footnote in the caption. There is no error, but it is written in two lines in the footnote. I also try \hyphenatedurl, \letterslash in the wiki, but it is no use. I am using "ConTeXt ver: 2020.12.22 22:14 LMTX”. Thank you for reading. Best regards, Dalyoung Here is a MWE. \useMPlibrary[dum] \unexpanded\def\myurl#1{% \bgroup{\hyphenatedurl{#1}}\egroup} \starttext \startplacefigure[] {\startcombination[2*1] {\externalfigure[dummyz][width=.35\makeupwidth]}{Pegasus\footnote{\myurl{https://www.mcescher.com/gallery\letterslash recognition-success/no-105-pegasus/}}} {\externalfigure[dummy][width=.35\makeupwidth]}{Birds\footnote{\myurl{https://www.mcescher.com/gallery/recognition-success/no-128-bird/}}} \stopcombination} \stopplacefigure \stoptext

Best practices for multi-part book
by Denis Maier 29 Dec '20

29 Dec '20

Hi, I need to typeset a book that, due to space constraints, is going to be published in two volumes. Both volumes together will contain about 1500 pages, both volumes should be continuously paginated, i.e. if volume 1 ends at page 700 volume 2 will start at 801 (After the frontmatter maybe.) Both volumes will have the same frontmatter, maybe a different subtitle. Oh, and of course, both volumes shall have a complete table of contents. How would you approach such a task. I'm inclined to just treat the the whole thing as a single book, and split the the PDF at some point. Or, are there better ways that I could consider? Best, Denis

About xdecimal
by Jairo A. del Rio 28 Dec '20

28 Dec '20

Hi, list. I've tried using the xdecimal library included with LuaMetaTeX and I have some remarks: 1. Shifts are decimal, not binary: 145 >> 1 gives 14. 2. Integer division (//) is not implemented. Is that by design? 3. Following 2, what would be the way to handle integer division, remainder... for large numbers? Thank you in advance. Best regards, Jairo

Diagnositics in LuaTeX
by Henri Menke 28 Dec '20

28 Dec '20

Dear lists, Recently I've been working a bit on PGF/TikZ and many times I wished I had certain metrics that are available in regular programming languages. In particular I am missing: - A callback that is triggered when a macro is defined. This would allow me to trap when a cs is defined in the wrong place. That could probably be done by overriding `\def` but there are some gotchas with prefixes, e.g. `\long\def`. - A callback that is triggered when a token is expanded (or executed in the case of primitives). In conjunction with the previous request, this would allow me to measure code coverage by comparing which macros are defined and which ones are used. - Switches to trap on certain pathological events. For example I want to trap when TeX inserts a frozen \relax because a number couldn't be read. Another thing I want to trap is `Missing character: There is no <char> in font <font>!`. There are probably more silent TeX errors that I currently don't have in mind. Are these things possible in LuaTeX right now or could they be made possible in the future? Kind regards, Henri

Questions concerning interfaces (and a feature request)
by Jairo A. del Rio 28 Dec '20

28 Dec '20

Hi, Hans and list. I want to know two things. 1. If the "option/content" pair could be enabled for hashes and arrays in interfaces.definecommand: \starttext \startluacode interfaces.definecommand{ name = "acommand", --This doesn't work --arguments = {"content", "array"}, arguments = {"array"}, macro = function(t) context(table.concat(t, " and ")) end } \stopluacode %No :( %\acommand{a, b, c, d, e, f} \acommand[a, b, c, d, e, f] \stoptext 2. Is "array" available for interfaces.implement in ConTeXt MkIV? The following crashes in MkIV, but is fine with LMTX: \starttext \startluacode interfaces.implement{ name = "anothercommand", public=true, arguments = {"array"}, actions = function(t) context(table.concat(t, " and ")) end } \stopluacode \anothercommand[a, b, c, d] \stoptext I'm using MkIV as is included in the LMTX distribution. Thank you very much. Best regards, Jairo :)

Generic fontloader and flush_components
by Marcel Fabian Krüger 27 Dec '20

27 Dec '20

Hi, in font-ots.lua (which becomes part of the generic fontloader) nuts.flush_components is used, while it seems to be defined for mkiv and generic in node-gcm.lua, but this file is not included in the packaged generic fontloader. Therefore the current luatex-fonts-merged.lua breaks with "trying to call a nil value (upvalue flush_components)". Could you please add a definition for nuts.flush_components in the generic version? Thanks, Marcel

Metafun: dotlabel issue in latest LMTX
by Otared Kavian 27 Dec '20

27 Dec '20

Hi Hans, The following (due to you and Aditya, discussed a few days ago) used to work with LMTX until version 2020-12-10, but it does not work anymore with LMTX version 2020-12-24 17:30. I wonder whether this is due to some changes you have made recently. %% begin squaredot-test.tex \startMPdefinitions newpath mydotlabelshape ; mydotlabelshape := fullcircle ; mydotlabeldiam := 12 pt ; vardef mydotlabel@#(expr s,z) text t_ = label@#(s,z) t_ ; fill (mydotlabelshape scaled 2mydotlabeldiam) shifted z t_; enddef ; \stopMPdefinitions \starttext \startMPcode newpath p ; p := (2cm, 3cm) -- (3cm, 5cm); mydotlabeldiam := 15pt; mydotlabelshape := fullsquare ; draw p ; mydotlabel(textext("\switchtobodyfont[8pt]" & "A"), point 0 of p) withcolor transparent("exclusion",.5,red) ; mydotlabel(textext("\switchtobodyfont[8pt]" & "B"), point 1 of p) withcolor transparent("exclusion",.5,red) ; \stopMPcode \stoptext %% end squaredot-test.tex I get an error message, which is obscure to me, saying: %-- begin error message excerpt metafun > log > error: Isolated expression metafun > log > metapost > log > metapost > log > <to be read again> metapost > log > ; metapost > log > <*> newpath mydotlabelshape ; metafun > log > metafun > log > I couldn't find an '=' or ':=' after the expression that is shown above this error message, so I guess I'll just ignore it and carry on. metafun > log > metapost > log > mydotlabelshape := fullcircle ; mydotlabeldiam := 12 pt ; vardef mydotlabel@##(expr s,z) text t_ = label@##(s,z) t_ ; fill (mydotlabelshape scaled 2mydotlabeldiam) shi... %-- end error message excerpt Best regards: Otared
