Index with distinguishable entries -- again
by Florian Grammel 27 Apr '17

27 Apr '17

Back in april 2012 Robert Blackstone asked some questions about indexing http://www.mail-archive.com/ntg-context@ntg.nl/msg63134.html i.a.: > For a book in the area of musicology I would like to make one register with > entries of different kinds, distinguishable by their appearance in the > register (or index or whatever). > The index entries will mostly be authors, including composers, musical terms > and musical compositions. The titles of the compositions and the foreign words > are set in italic characters throughout in the text of the book. > What I would like is to be able to distinguish all entries according to whether > they are treated in the text, are shown in a musical example, or are mentioned > only in a foot- or endnote. > > In many books page numbers indicating illustrations are set in italics. > Pagenumbers indicating foot- or endnotes often have a suffix "n". > His other question were resolved, but this one remained unanswered, apart from that two other users also wanted to do exactly the same thing. I would like to do something very similar and was wondering: Has this been addressed/solved since then? Thanks in advance! Best, Florian. ____________________________________________ Florian Grammel Copenhagen, Denmark

Re: [NTG-context] eqalignno failin

I had this code: 99 \placeformula\startformula 100 \eqalignno{ 101 >> H(I,J) &= H(I) + H(J|I)\qquad&\hbox{\ineq[eq:equivoc]}\cr 102 W(I,J) &= H(J) - H(J|I)\qquad&\hbox{\ineq[eq:wedinfo]}\cr 103 } 104 \stopformula On 26 Apr 2017, at 16:38, Otared Kavian <otared(a)gmail.com<mailto:otared@gmail.com>> wrote: It is better to use the construction such as: \placeformula \startformula \startalign \NC H(I,J) \NC = H(I) + H(J|I) \NR[eq:equivoc] \NC W(I,J) \NC = H(J) - H(J|I) \NR[eq:wedinfo] \stopalign \stopformula Below I illustrate why this is not better, and I did not find a way how to remedy its effect. This is the original produced by the \eqalignno. See the active links to previous equations in green, produced by my \ineq-macro. The equation numbers here are from the 7th chapter, in the latter (shortened) examples the chapter number will be 1. [cid:6BEAFFEE-7FE7-4CE4-AD45-DB0341A2EA25] The suggested code gives: [cid:CEBB66EC-83A5-4A10-A7E3-729FBBB24BD9] Wrong because the numbers should refer to equations 1.21 and 1.28 instead of numbering forward. Putting my \ineq-macro there \NC W(I,J) \NC H(J) - H(J|I)\NR\hbox{\ineq[eq:wedinfo]} gives an equally unacceptable result: [cid:ACE1072E-59D0-4310-8FC5-4E9E1FF3485C] On 26 Apr 2017, at 16:38, Otared Kavian <otared(a)gmail.com<mailto:otared@gmail.com>> also wrote: Hi Hans, Since a few weeks (or months?…) ago the use of \eqno and \eqalignno has been changed in mkiv. A remark afterwards I really regret making. But I cannot understand why \eqalignno and friends have been changed from their original behaviour. It breaks older products of mine without warning. In fact I wouldn't have spotted this, had not a colleague drawn my attention to it. Is this the only math macro behaving differently, giving a TeX error? Are there others? I cannot but ask most strongly not to let mkiv deviate in this manner from basic TeX's behaviour. I am doing a lot in ConTeXt but I mix it with parts of basic TeX. When I can no longer trust TeX doing like TeX I really don't know how to go further. Please return the original behaviour. Thanks for looking into it. Hans van der Meer

How to go through a vbox line by line in Lua?
by Henri Menke 26 Apr '17

26 Apr '17

Dear list, Recently I answered a question on TeX.SX where it was necessary to go through an already typeset vbox and examine it line by line. Therefore I used the macro \eatlines from Viktor Eijkhout's "TeX by Topic", here a version tailored to my needs: \def\eatlines{% \setbox\scratchbox=\lastbox \ifvoid\scratchbox\else \unskip\unpenalty {\eatlines}% \setbox\scratchbox=\hbox{\unhbox\scratchbox}% % Do something with scratchbox, e.g. examine width \fi } It is then used like \vbox{ ... some content ... \par\eatlines} The macro goes through all hboxes (lines) in the vertical list until there is none left (\ifvoid) and unpacks each hbox into a new one. I was wondering, can the same thing be done in Lua (with probably less and more readable code)? Kind regards, Henri

eqalignno failing

Linking local resource
by Nicola 25 Apr '17

25 Apr '17

I'd like to have links in my PDF to external resources (videos, movies, or non-embeddable file types) stored locally. Ideally, I'd like to use relative links, so that I can move the folder containing the PDF and the resources, and a cross-platform method (I'm on macOS). Is that possible? Nicola

MP & text transparency

Hello, suppose having the following code: ---- \startuseMPgraphic{T} newpath rc; rc := fullsquare xyscaled (50mm, 50mm); color col; col := (1.,.1,.1); draw rc withpen pencircle scaled (2.5mm) withcolor %col; transparent(1, .4, col); draw thelabel(btex\setupbodyfont[sans,35mm] Test etex, (80mm, 50mm)) withcolor %col transparent(1, .4, col) ; \stopuseMPgraphic \defineoverlay[T][\useMPgraphic{T}] \setupbackgrounds[page][background={foreground,T}] \startTEXpage[width=200mm,height=200mm] \stopTEXpage ---- The rectangle drawn is transparent, which is OK. But the text "Test" is not, is it fully red; why? How to specify text to be partially transparent, too? TIA. Best regards, Lukas -- Ing.

Long and slender floating tables
by Javier M Mora 23 Apr '17

23 Apr '17

Hi, I have several long and slenders tables like this: -------8<------- \starttext Some Text at start. % Point bA \placetable[split]{My long table}{ % Point bB \bTABLE[split=repeat] \bTABLEhead \bTR\bTD one \eTD\bTD two \eTD\bTD three \eTD\eTR \eTABLEhead \bTABLEbody \dorecurse{100}{\bTR\bTD 1 \eTD\bTD 2 \eTD\bTD 3 \eTD\eTR} \eTABLEbody \eTABLE % Point eB } % Point eA Some Text at the end. \stoptext -------8<------- Typesetting this tables are quite ugly because the wide white space each side. I think the ideal solution is to place columns inside the floating but context garden wiki says float and columns doesn't work very well. I've tried put in Points "bA" and "eA" and in "bB" and "eB" the commands \startcolumn - \stopcolumn \startsinglecolumn - \stopsinglecolumn but unsuccesful. I am thinking to cut manually the table but there are enough amount of table to don't like the idea. In the worst case, I'll force tables to start a page and cut them manually. Questions: * Is there a easy automatically system to cut tables in columns? How? * Do you think/know a better way to show/expose data with this shape (long rows and few columns)? Thanks. Javier M. Mora
