Bug in columns

Hi, There are some footnotes in my text. When I use \startcolumns...\stopcolumns, the locations of footnotes are not right. Please see the followging sample: \starttext If there is a footnote here\footnote{It's a footnote!}. \startcolumns[n=2] \input knuth \column \input knuth \stopcolumns The result is not right. \stoptext The result is attached. My lmtx version is 2023.03.10 12:18. foo.pdf <https://drive.google.com/file/d/1zSUTCVsssoET9Pr88f8VIzQGdMnnzpjg/view?usp=…> -- Best regards, Li Yanrui

How to extend an existing macro to take optional parameters?
by Bruce Horrocks 15 Mar '23

15 Mar '23

I have an existing macro that I'd like to extend. The current definition is \define[3]\mycommand{...} which I'd like to extend to take an optional 4th parameter plus an optional setup parameter. Thus I currently invoke it as: \mycommand{aa}{bb}{cc} and I'd like to be able to extend it so that any of the following can be used: \mycommand{aa}{bb}{cc} \mycommand{aa}{bb}{cc}{dd} \mycommand{aa}{bb}{cc}{dd}[ee] or \mycommand[ee]{aa}{bb}{cc}{dd} % if this is more the ConTeXt way where {dd} is the optional extra parameter and, if it is present, then [ee] can also be optionally added (because it controls how {dd} is printed). If it helps, the actual body of the macro can easily be a call to Lua so it's fine if the function takes 5 params where 4 and 5 can be nil or empty strings. I've trawled through syst-aux.mkiv but it only covers optional numbers of [ ] or { } but not combinations of both (which given the vast numbers of combinations is perhaps not surprising!). Have I missed something obvious that would help me? Regards, — Bruce Horrocks Hampshire, UK

\unit parser ignoring case, in some cases.
by Gavin 14 Mar '23

14 Mar '23

Hello list, I continue to work with the \unit command, and found some behavior very surprising. When I try to register units with capital letter names, it breaks lowercase metric prefixes. For example, registering C=coulomb, K=kelvin and N=newton breaks metric units cm, kg, and ns. The file below demonstrates the behavior. Obviously, I can use full names in my document. However, I would like the standard SI symbols, which are single capital letters, to work for me and my less TeX-savvy colaborators. Thanks! Gavin \starttext Units does not completely ignore case. \startformula \unit{3 meter} \qquad \unit{6 Meter} \qquad \unit{3 mEtEr} \qquad \stopformula Units with lowercase prefixes (c, k, n). \startformula \unit{3cm} \qquad \unit{6kg} \qquad \unit{3ns} \qquad \stopformula Units with capital letters, called with names (coulomb, kelvin, newton). \startformula \unit{3 coulomb} \qquad \unit{6 kelvin} \qquad \unit{3 newton} \qquad \stopformula Units with capital letters, called with the capital letter (C, K, N) fail. \startformula \unit{3 C} \qquad \unit{6 K} \qquad \unit{3 N} \qquad \stopformula Now I register some units with capital letter names: C=coulomb, K=kelvin, N=newton. \registerunit[unit][ C=coulomb, K=kelvin, N=newton] Units called by capital letter (C, K, N) now work. \startformula \unit{3 C} \qquad \unit{6 K} \qquad \unit{3 N} \qquad \stopformula However, units with lowercase prefixes (c, k, n) are broken. \startformula \unit{3cm} \qquad \unit{6kg} \qquad \unit{3ns} \qquad \stopformula \stoptext

natural table oddities
by Henning Hraban Ramm 14 Mar '23

14 Mar '23

Working on the documentation for “natural tables” I stumbled upon a few oddities/problems. I’d like to know if there are misunderstandings on my part or if the behavior is intentional. BTW enattab.pdf is missing in the LMTX distribution. ## Options * before/after/inbetween values don’t appear anywhere. * spaceinbetween should insert between rows, but nothing happens. * splitoffset doesn’t seem to change anything. * What’s samepage for? ## Addressing cells * It’s not possible to address single cells with \setupTABLE, or is it? * There’s \setupTABLE[header], but not "footer" (or "section"); since we have TABLEhead and TABLEfoot, IMO "head" and "foot" would make sense. * Row 1 is the first row of TABLEbody. I couldn’t find how to address the first line of TABLEbody. * Is it possible, and how, to use odd/even only for the body? * If I format a column, e.g. \setupTABLE[c][-1][color=red], body and foot are formatted, but not the same column in header. (I found out, if I use TD instead of TH in the header, it works.) * I don’t understand the addressing options "start" and "one". ## Formatting * maxwidth doesn’t seem to have an effect, neither on the whole table nor on a column. * textwidth works only for the whole table. * width gets stretched if option=stretch; i.e. you can’t fix the width of single cells or columns. ## Page breaking * What’s the difference between [split=repeat] and [split=yes,header=repeat], i.e. which sense makes the header option)? * Is there an option to repeat the footer (as the last line of each page)? (I’d imagine to use it in an invoice or similar calculation for a subtotal – that would imply some more magic…) Hraban

extra lines in PDF annotations
by Pablo Rodriguez 14 Mar '23

14 Mar '23

Dear list, using current latest from 2023.03.10 12:18, I have this XML sample: <pre> <element/> </pre> And the following environment: \setupinteraction[state=start] \startxmlsetups xml:text \xmlsetsetup{\xmldocument} {pre} {xml:copy:html} \stopxmlsetups \xmlregistersetup{xml:text} \startxmlsetups xml:copy:html \xmltobuffer{#1}{.}{text} \comment[location=inmargin,buffer=text]{} \attachment[method=hidden, name=attach.xml, buffer=text] \null \stopxmlsetups If I save the XML file with Windows EOL chars (CR LF), I get extra blank lines in the PDF annotation. Everything is fine, if XML has Unix line endings (LF char). Attachment contains the proper line ending in each case. Could anyone confirm what appears to be a tricky issue? Many thanks for your help, Pablo

Did dotless i disappear ?
by Otared Kavian 13 Mar '23

13 Mar '23

Hi Hans, I just noticed that the dotless i « \i » is not anymore recognized in ConTeXt. Of course one can nowadays find other ways to have it typeset, but in old documents which are included as inputs one has to correct this manually (for instance in French « connaître » was typed as « conn\^{\i}tre »). Here is an example. \starttext Bío Bío (works fine…) B\'{\i}o B\'{\i}o % this gives an error \stoptext Best regards: Otared

Bug in maths environment: thematrix
by Otared Kavian 12 Mar '23

12 Mar '23

Hi Hans, I noticed that in some situations the command \thematrix does not show all its arguments correctly: some parts are omitted in the typeset formula. In some occasions adding some groupings solves the issue, but not always. I noticed this bug two weeks ago, but could not produce a minimal example until now… Please see below, in particular the output for the matrices M_1, M_2 and M_3… Best regards: Otared % begin bug-thematrix.tex \starttext \startformula M_{1}(t) := \thematrix{{\rm e}^s ; {\rm e}^t}, \qquad B_{1}(t) := \thematrix{1 , {\rm e}^t}, \stopformula \startformula M_{2}(t) := \thematrix{{{\rm e}^s} , {{\rm e}^t}}, \qquad B_{2}(t) := \thematrix{0 ; {{\rm e}^t}}, \stopformula \startformula M_{3}(t) = \thematrix{{\rm e}^s, {\rm e}^t ; 0 , {\rm e}^t}. \stopformula \startformula M_{4}(t) = \thematrix{1, {{\rm e}^t} + 1 ; 0 , {{\rm e}^t}}. \stopformula \stoptext % end bug-thematrix.tex
