Suggestions for more math classes?
by Mikael Sundqvist 16 Feb '22

16 Feb '22

Dear all, While discussing spacing in math with Hans, we have come to the conclusion that to have better control and cleaner code there might be a good idea to have more math classes than the usual ones in TeX (ord, op, bin, rel, open, close, punct, inner (and some that we need not to think about)). So far, Hans has implemented frac and rad for fractions and radicals. The fractions has been a funny construction, being put inside empty delimiters, and so surrounded by the \nulldelimiterspace (which has been set to 1.2pt, independent of font size). Now we have better control of the spacing around fractions. Hans has opened up (even in the code) for the addition of more classes. The overall aim is to have a more coherent and logical way of typing math, without manual adding of (arbitrary) spaces every now and then. For example, we have always written \int f(x)\, dx to have a thin space between the closing parenthesis and the d in integrals. There will (most likely) be a differential class. Since the d might occur in other places in a formula with integrals, one cannot just simply give the letter d the differential class, and we are currently discussing the correct way for the user to type it. If you have suggestions, please let us hear! Some further suggestions by Hans are (see below for two more) 13 imaginary 14 differential 15 exponential 16 function Q1: Do you have any further suggestions on new classes (or comments on these)? It might be good to think about situations where you have felt that you need to insert manual spaces such as \, or \! to obtain a better result. I give one contribution: I asked a colleague to look in his TeX files for manual spaces, and he came up with several \, (usually before the d in integrals) but also with \!. This \! occurred mostly in fencing situations to have the exponent come a bit closer to the closing parenthesis. \left( \frac{x}{2} \right)^{\! k+2n} I have seen this in many places before, so no originality is claimed. Two more classes that we thought of are under and over. Say that we have a\overbar{bc}d. Should the spacing between a and the \overbar{bc} and the spacing between \overbar{bc} and d always be tight? If so, these might just be ord, and no new class needed (although one could argue for adding the classes now, set them up as ord, and thus being able to configure them according to taste/need). Q2: Do you have any real examples of constructions with \overbar, \underbar, \overbrace, ... or if you have any strong opinion, please raise your voice! /Mikael

Hi, In case I forget (and someone is in wikify mode) ... the next upload will have a new command: test \diagnostic {here 1} test test \diagnostic[2] {here 2} test test \diagnostic[.05]{here 3} test which will show up as [[diagnostic]] > here 1 [[diagnostic]] > here 2 (sleep: 2) [[diagnostic]] > here 3 (sleep: 0.05) and which can be used for debugging styles. It might evolve.

sorting for particular sub entries to register
by jbf 01 Feb '22

01 Feb '22

Let me come back to the unresolved (for me) question of two situations in sub entries to a book index (register). Sub entries that have formatting or sub entries that are surrounded by quote marks (straight or curly, it makes no difference) do not appear in the correct alphabetical order. Two attempts on my part: text before \index[Plenary+periti]{Plenary Council+{\it periti} (experts)} text after. text before \index{animals+‘special kinds’} text after. Or alternatively, \index[animals+special]{animals+‘special kinds’} The setup for my register is a pretty standard one. The processor is not for the 'periti' case above but I use it for book titles. \setupregister[index][n=1,method={zc,pc,zm,pm,uc},style=WORD] \defineprocessor[special][style=italic] In the periti case it is the \it command that clearly interferes with correct alphabetic positioning in the sub entry list. Placing +periti in the key does not overcome that problem. In the ‘special kinds’ case it is the initial single quote mark (‘) that causes the problem. The item comes last in the sub entry list. And if i include a key [special], then it comes first in the sub entry list. Either way, it is out of the desired sorting order. I believe I have followed the helpful suggestions of various ones, but it is always possible that I have not fully understood those suggestions. The reality is that at the moment the issue remains unresolved for me. Any further wisdom out there to offer me? Julian

paragraph notes located in text
by Pablo Rodriguez 01 Feb '22

01 Feb '22

Dear list, with current latest (2022.01.21 20:13), I cannot get paragraph footnotes when located in text. Here you have the mandatory sample: \setuppapersize[A6] \showframe\showgrid %~ \setupnote[footnote][paragraph=yes] \setupnote[footnote][location=text, paragraph=yes] \setupnotation[footnote][alternative=serried, width=broad] \starttext \startlinenumbering[step=3] \dorecurse{25} {a\footnote{b} } \stoplinenumbering \placenotes[footnote] \stoptext I already asked this twice (https://mailman.ntg.nl/pipermail/ntg-context/2022/104770.html, https://mailman.ntg.nl/pipermail/ntg-context/2022/104929.html) Could anyone confirm that the is no way to get paragraph notes when location is text, or tell me what I’m missing? Many thanks for your help, Pablo

doublesided margin page number

control cite - bibliographical references
by r.ermers＠hccnet.nl 30 Jan '22

30 Jan '22

Dear list, I am struggling with the color of bibliographical references. I found (Ulrike’s) hack to render the items in the bibliography the regular color (black): \appendtoks \iflocation \letinteractionparameter{color}\empty \fi \to \everybtxlistrendering. There the problem seems to relate to the use of \setupinteraction. Now, in my citations (\cite[Douma1979a]) the authornames are still colored. Douma, 1979a, 86 I examined the contextgarden site, read and tried the answers to previous questions, but could not find out how to do this. Is there a way to control the author names? Thank you in advance, Kind regards, Robert

Re: [NTG-context] registers, how to ignore quote marks
by jbf 30 Jan '22

30 Jan '22

No, I had already tried that. It places the subentry at the top of the list of subentries, not in its correct alphabetical order. Using the example below, I assume you meant (I am including text before and after): The \index[Plenary+periti]{Plenary Council+{\it periti} (experts)} group comprises 10 members. There are nine subentries altogether, and quite a number under 'p', like \index{Plenary Council+preparations for}. The italicised /periti /should come just before the latter (preparations for) but, using the double key above it comes first in the list. The same happens with the subentry surrounded by single quotes. It too comes first in the list if I use a double key. So clearly it is the fact that there is formatting ({\it something}) or quotes ({‘word’}) in a subentry that causes the problem, and I am wondering how to overcome this.

Well done Adam - or should I say well read in the Wiki! For all my reading of it I still hadn't cottoned on to that. There are several of these cases, but I have been able to fix them all now. Thank you. Any thoughts (but I'm pretty sure this isn't fully explained in the wiki) how I can get part of the index entry in italics and part normal? That might be a bit more difficult I think.

How to stop \placefigure from floating off to some other page?
by Joel 30 Jan '22

30 Jan '22

When I used `\placefigure`, ConTeXt often puts the figure on a completely different page, my readership of young students is getting confused where the image is. How can I have all of my `\placefigure` in the entire document appear exactly where called, even if that means having to place it on a new page with lots of space before it or even a new page afterwards? I need it to show up in the order it was called. I think `\setupexternalfigures[location=]` should provide the solution, but cann't figure what is the correct location, I'm not seeing that in the manual anywhere.
