adjusting vertical space
by jbf 25 Nov '21

25 Nov '21

The following MWE produces a passable result for a half-title page, but I need to reduce the vertical space between 'A JOURNEY' and 'from the' so that the 'h' of the 'the' is just touching the baseline of the 'R' in JOURNEY. At the moment there is some distance between them. I thought I could do this with \setupinterlinespace[] (not represented in the MWE because it did not work) but no matter what dimensions I put in there, it makes no difference. Is there another way I can make infinitesimal adjustments to distance between the two lines in question?

Macro for a comma separated list of authors
by Andres Conrado Montoya 25 Nov '21

25 Nov '21

I'm trying to produce a document with several authors, using macros for comma separated lists. My MWE is as follows: %%%%%%%%%%%%%%%%%%%%%% \def\autores{% {Luis David Gómez-Méndez, Ph. D.}, {Adriana del Pilar Pulido-Villamarín, M. Sc.}, {Rubiela Castañeda-Salazar, M. Sc.}, {Juan Carlos Ulloa-Rubiano, Ph. D.}, {Adriana Matiz-Villamil, M. Sc.}% } \def\lastAutor{Fidson Juarismy Vesga-Pérez, Ph. D} \def\autorParaLista#1{#1;\space} \def\listaAutores{\processcommacommand[\autores]\autorParaLista & \lastAutor: autores.} \starttext \listaAutores \stoptext %%%%%%%%%%%%%%%%%%%%%%% So far, no luck trying to extract the last item from a comma separated list. That's the reason I created a "\lastAutor" macro, so I can treat the last one differently. This produces: %%%%%% Luis David Gómez-Méndez, Ph.D.; Adriana del Pilar Pulido-Villamarín, M. Sc.; Rubiela Castañeda-Salazar, M. Sc.; Juan Carlos Ulloa-Rubiano, Ph.D.; Adriana Matiz-Villamil, M. Sc.; & Fidson Juarismy Vesga-Pérez, Ph.D: autores. %%%%%% However, what I'm trying to get is: %%%%%% Luis David Gómez-Méndez, Ph.D.; Adriana del Pilar Pulido-Villamarín, M. Sc.; Rubiela Castañeda-Salazar, M. Sc.; Juan Carlos Ulloa-Rubiano, Ph.D.; Adriana Matiz-Villamil, M. Sc. & Fidson Juarismy Vesga-Pérez, Ph.D: autores. %%%%%% Which is very close to what I need, except the ";" just before the "&". So the question is: is it possible to do this in a more effective or simpler, or better way, and write a macro that outputs something like "Author1; Author2; Author3 & Author4: authors.", given a comma separated list of authors? -- Andrés Conrado Montoya Andi Kú andresconrado(a)gmail.com http://sesentaycuatro.com http://messier87.com http://chiquitico.org ---------------------------------------- Los fines no justifican los medios, porque la medida verdadera de nuestro carácter está dada por los medios que estamos dispuestos a utilizar, no por los fines que proclamamos. ---------------------------------------- “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.

fixing indentation of xtable inside item
by Andres Conrado Montoya 23 Nov '21

23 Nov '21

Considering the following MWE, I would like to know how I can get the table inside the item to be aligned with the item. It seems the tabel takes the width right, but it gets pushed to the left, disregarding the item's indentation. I think I read about this behaviour somewhere, but I have spent 4 hours looking for it in the manuals and I can't find it. :( Any help would be appreciated. %-------------------------startwme \starttext \startitemize \item Determine la {\sc an} de cada objetivo del microscopio, con los ángulos de la tabla y teniendo en cuenta lo siguiente: $n_{\text{aire}} = 1$ y $n_{\text{aceite de inmersión}} = 1.515$: \blank \startxtable[align=middle,option=stretch] \startxtablebody[body] \startxrow \startxcell Objetivo 4x \stopxcell \startxcell $n=1$ \stopxcell \startxcell $\alpha=5.8$ \stopxcell \startxcell {\sc an}$=$ \stopxcell \stopxrow \startxrow \startxcell Objetivo 10x \stopxcell \startxcell $n=1$ \stopxcell \startxcell $\alpha=14.5$ \stopxcell \startxcell {\sc an}$=$ \stopxcell \stopxrow \startxrow \startxcell Objetivo 40x \stopxcell \startxcell $n=1$ \stopxcell \startxcell $\alpha=40.5$ \stopxcell \startxcell {\sc an}$=$ \stopxcell \stopxrow \stopxtablebody \startxtablefoot[foot] \startxrow \startxcell Objetivo 100x \stopxcell \startxcell $n=1.515$ \stopxcell \startxcell $\alpha=55.6$ \stopxcell \startxcell {\sc an}$=$ \stopxcell \stopxrow \stopxtablefoot \stopxtable \stopitemize \stoptext %-------------------------startwme -- Andrés Conrado Montoya Andi Kú andresconrado(a)gmail.com http://sesentaycuatro.com http://messier87.com http://chiquitico.org ---------------------------------------- Los fines no justifican los medios, porque la medida verdadera de nuestro carácter está dada por los medios que estamos dispuestos a utilizar, no por los fines que proclamamos. ---------------------------------------- “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.

Confusing interaction between \writetolist and bookmarks (bug?)
by musa furber 22 Nov '21

22 Nov '21

I am relatively new to ConTeXt and have encountered something that does not work as I expected it to based on various documentation and examples. My book design requires the front matter to contain an abridged table of contents just for chapters, and a detailed table of contents in the back matter. Everything worked fine -- including the PDF bookmarks and table of contents -- until I started using \writetolist to manually inject additional sections and subsections into their respective lists. The manually injected entries do show up (as I expected), but their corresponding PDF bookmarks get repeated (not what I expected). Here is a M(not)WD: ###begin \setupinteraction[state=start] \placebookmarks[chapter, section][chapter, section] \setupinteractionscreen[option=bookmark] \starttext \startfrontmatter \title{Contents} \placelist[chapter] \stopfrontmatter \startbodymatter \chapter{Chapter ONE} \section{Section ONE} \writetolist[section]{}{Section via writetolist ONE} \chapter{Chapter TWO} \stopbodymatter \startbackmatter \chapter{Detailed Table of Contents} \placecontent[criterium=all] \stopbackmatter \stoptext ###end The repetitions go away when any one of the following is done: -- commenting out the front/body/back commands -- commenting out both contents at front and back -- commenting out just back contents -- commenting out the \writetolist Have I misunderstood something? Many thanks, Musa

Problem with \head inside \itemize
by Jean-Philippe Rey 22 Nov '21

22 Nov '21

Dear list, The following code worked perfectly well with ConTeXt ver: 2021.01.05 10:45 LMTX but produces an error with the current LMTX version (at least since ConTeXt ver: 2021.09.26 17:00 LMTX).

Bug in lmt_arrow
by Aditya Mahajan 22 Nov '21

22 Nov '21

Hi, There is a bug in lmt_arrow. If given a "non-cycle" path, lmt_arrow completes the cycle. \starttext \startMPcode newpath p; ahfactor := 5; p := origin .. (1cm, 1cm) .. (2cm, 0); draw lmt_arrow [ path = p, location = "percentage", percentage = 50, alternative = "curved", ] withpen pencircle scaled 1bp; \stopMPcode \stoptext With 2021.11.11, I get the attached file. Note that lmt_arrow has drawn the "cycle" version of the path, even though p does not have a cycle. I have looked at the code and cannot figure out why this is happening. Thanks, Aditya

Enumeration numbering in the left margin
by kauśika 21 Nov '21

21 Nov '21

Dear list, I have the following enumeration block. \defineenumeration[verse] \setupenumeration[verse] [alternative=leftmargin, text=, width=fit, distance=1em, way=bysection] I actually want to (flush) left align the enumeration's number inside the left margin and give it a blue color. But even if I have \setupmargindata[inleftmargin][color=bblue4,align=flushleft] there is no alignment, no color. However, if I do \setupenumeration[verse] [alternative=leftmargin, text=, width=\leftmarginwidth, headcolor=bblue4, distance=0em, way=bysection] I am able to get the desired effect. Is this the 'correct' way to do it? I mean to ask, am I doing something wrong with \setupmargindata or is this expected behaviour. Thanks, kauśika

Neste itemize in table (or vice-versa?)
by Alexandre Christe 20 Nov '21

20 Nov '21

Dear all, I'm trying something out in LMTX, which is to combine itemize with a table. Application could be to put a question and the answer in the next column. A minimal example would be: \starttext \startitemize [a] [right=),stopper=] \bTABLE[frame=off] \setupTABLE[column][1] [width=.3\textwidth] \setupTABLE[column][2] [width=.6\textwidth] \bTR \bTD \item Something \eTD \bTD Something \eTD \eTR \bTR \bTD \item Something \eTD \bTD Something \eTD \eTR \bTR \bTD \item Something \eTD \bTD Something \eTD \eTR \bTR \bTD \item Something \eTD \bTD Something \eTD \eTR \eTABLE \stopitemize \stoptext The numbering unfortunately starts with i) instead of a). Any recommendation which approach shall be preferred? Thanks in advance!

\doifanydefinedelse, \doifallundefinedelse
by Joey McCollum 19 Nov '21

19 Nov '21

I was checking the "Branches and Decisions" wiki entry at https://wiki.contextgarden.net/System_Macros/Branches_and_Decisions, and I saw that ConTeXt has a useful \doifalldefinedelse macro that checks a comma-separated list of macro names and proceeds according to whether or not all of the macros with those names are defined. I was curious as to whether or not there is also a \doifanydefinedelse (or, equivalently, a \doifallundefinedelse) macro that would check if *any *of the macros with names in the comma-separated list is defined (or, equivalently, if all of them are undefined). I don't see any mention of such a macro on the wiki page, so I wanted to ask: has something like this already been implemented, and if not, is there a simple way to do a check like this? This functionality would be useful for performing some checks on a key-value assignment, and passing a comma-separated list to a macro would be much cleaner than doing a bunch of nested if-else blocks.
