Spacing after combination
by Marco Patzer 16 Jul '19

16 Jul '19

Hi! Is there a way to influence the spacing after a combination is placed? \useMPlibrary [dum] \starttext \startcombination [2*2] \startcontent \externalfigure \stopcontent \startcaption Foo \stopcaption \startcontent \externalfigure \stopcontent \startcaption Bar \stopcaption \startcontent \externalfigure \stopcontent \startcaption Lorem \stopcaption \startcontent \externalfigure \stopcontent \startcaption Ipsum \stopcaption \stopcombination \samplefile{knuth} \stoptext I know I could wrap it in a float and use the float to control the spacing, but it would be great if I could do without that float.

Columnsets not balanced
by Sytse Knypstra＠home.nl 15 Jul '19

15 Jul '19

Dear list, In the following example I would like to have the two columns balanced, i.e. with equal number of lines in both columns. But contrary to the option in the definition, all text is put in the leftmost column and the right-hand column remains empty. \definecolumnset[Two][balance=yes] \starttext \startcolumnset[Two] \input knuth \stopcolumnset \stoptext How can I automatically obtain balanced columns?

noindent vs noindentation in strc-con
by Aditya Mahajan 12 Jul '19

12 Jul '19

Hi, Why do all the rendering setups in strc-con.mkvi use \noindent? Can the \noindet be replaced by \noindentation? \noindent has some side effects. For example, consider this recent question on TeX.SE: https://tex.stackexchange.com/questions/499464/context-empty-line-in-enumer… which basically boils down to the difference between: \showboxes \starttext \noindent \inmargin{Example 1} \startitemize \item This is how enumeration works. \stopitemize \inmargin{Example 2} \startitemize \item This works correctly \stopitemize \stoptext Note that the first example has an extra space before the itemize. In principle, replacing \noindent by \noindentation fixes the extra line break, but it does not work with enumerations because it uses \inmargin[scope=local]: \showboxes \starttext \noindentation \inmargin[scope=local]{Example 1} \startitemize \item This is how enumeration works. \stopitemize \inmargin[scope=local]{Example 2} \startitemize \item This works correctly \stopitemize \stoptext where the box containing "noindentation" is misgligned. So, two questions: * Why is \noindent used instead of \noidentation? * Is there a bug with scope=local? Aditya

reference containing parentheses causes trouble
by Sanjoy Mahajan 12 Jul '19

12 Jul '19

Dear List, Warning: The following may be a bug or feature or just my misunderstanding! It seems that parentheses cause trouble in references. MNWE: \starttext \section[sec:one(two)]{One} As you see in sec.~\in[sec:one(two)], \stoptext The "in sec.~\in[sec:one(two)]" typesets as "in sec. ??" and the log shows: references > start missing references references > 1 [][sec:one(two)] references > stop missing references (It all works fine upon deleting "(two)" throughout.) Is this behavior known and expected? If it is, I'll add a note to the "References" page on the wiki. -Sanjoy

registers: subentry indentation different from word--number gap?
by Sanjoy Mahajan 12 Jul '19

12 Jul '19

I don't think the current behavior is a bug, so the following is a feature request: With the following fairly minimal example \setupregister[index][indicator=no, distance=0.5em] \starttext ABC\index{x}DEF\index{x+yyz} \blank \placeindex \stoptext the distance parameter sets (1) the hanging indentation of the 'yyz' subentry and also (2) the distance between an entry and its pagenumber. (That's what a look at strc-reg.mkiv shows too.) It's a matter of taste, but my eye thinks that 0.5em is right for no. 2, but too small for no. 1 -- whereas the default (1em) is just right for no. 1 but too large for no. 2. Thus, could the two dimensions be decoupled and bcome settable indepently? Perhaps keep 'distance' for the entry--pagenumber distance (no. 2), which is its meaning on the wiki, and invent 'subdistance' for the hanging indent (no. 1)? I've just realized a cheap hack to do the same, so maybe it's not worth messing with backward compatability by adding a new parameter. The hack: \def\blah#1{#1\hskip-0.5em} \setupregister[index][indicator=no, distance=1em, textcommand=\blah] -- -Sanjoy <http://savelongwharfpark.org/> Save Long Wharf Park in Boston Harbor! <http://streetfightingmath.com/> Six reasoning tools to make hard problems easy.

Strange error updatng LMTX

When updating my LMTX installation today, I got this: tex error > tex error on line 179 in file /home/conrado/Apps/lmtx/tex/texmf-context/tex/context/base/mkiv/strc-flt.mkvi: !

Seems to affect the floats mechanism. Andrés Conrado Montoya http://chiquitico.org

Split extreme tables across tables
by Thangalin 10 Jul '19

10 Jul '19

The following document does not split across tables, which is a little surprising: \starttext \startplacetable[title={Average Annual Temperatures}] \startxtable \startxtablehead[head] \startxrow \startxcell[align=middle,width={0.10\textwidth}] Year \stopxcell \startxcell[align=middle,width={0.14\textwidth}] Value \stopxcell \stopxrow \stopxtablehead \startxtablebody[body] \dorecurse{100}{% \startxrow \startxcell[align=middle,width={0.10\textwidth}] 1880 \stopxcell \startxcell[align=middle,width={0.14\textwidth}] 0.1146 \stopxcell \stopxrow} \stopxtablebody \startxtablefoot[foot] \startxrow \startxcell[align=middle,width={0.10\textwidth}] 2018 \stopxcell \startxcell[align=middle,width={0.14\textwidth}] 1.014 \stopxcell \stopxrow \stopxtablefoot \stopxtable \stopplacetable \stoptext I'd have thought the default behaviour would be to split because the alternative is for the table content to scroll into the footer and off the page. A fix is to use: \startplacetable[title={Average Annual Temperatures}, location={split}] However, when the document is generated using pandoc, injecting location={split} is not feasible. It would be convenient if there was a way to use setups to override the location option for \startplacetable. Henri Menke provided a work around: let\oldstartplacetable\startplacetable \unexpanded\def\startplacetable{\dosingleempty\newstartplacetable} \def\newstartplacetable[#1]{\oldstartplacetable[#1,location={split}]} See: https://tex.stackexchange.com/a/499453/2148 This does the job, but it doesn't feel like the ConTeXt way. How would you use setups to enable page splitting on extreme tables? Thank you!

an object representation of the node list of a paragraph: a lua table or a JSON
by mf 10 Jul '19

10 Jul '19

Hello list, i'd like having an object representation of a typeset paragraph or even a page, preferably as a JSON object, but a Lua table is equally good. My reference is section "4.4 Node lists" of the CLD manual. Before writing an iterator over the list of nodes of a paragraph, figuring out all the possible nodes and their fields, i'm wondering if there's some hidden tool in the ConTeXt coffer to simplify the task. Best wishes, Massimiliano
