error bar gap with pgfplots/tikz and custom colour
by Joshua Krämer 20 Jan '14

20 Jan '14

Dear list, I'm using pgfplots to create some bar charts with error bars, and I want to use custom colours for them. This works, but if I mix a custom colour with another colour, it results in a gap between the error bar line and the error bar mark. If two custom colours are mixed, the gap seems to be doubled. Mixing with predefined colours works normally. MWE: \usemodule[tikz] \usemodule[pgfplots] \definecolor [Blue] [h=3465a4] \definecolor [White] [h=ffffff] \pgfplotsset{compat=newest} \starttext \starttikzpicture \startaxis[ybar, error bars/y dir=both, error bars/y explicit] \addplot+[blue!50!white] coordinates {(1,5) +- (0,3)}; \addplot+[Blue] coordinates {(1,5) +- (0,3)}; \addplot+[Blue!50!white] coordinates {(1,5) +- (0,3)}; \addplot+[Blue!50!White] coordinates {(1,5) +- (0,3)}; \stopaxis \stoptikzpicture \stoptext Kind regards, Joshua Krämer

issues with \setuplist
by Pablo Rodriguez 19 Jan '14

19 Jan '14

Dear list, generating a table of contents with the following sample: \setupinterlinespace[line=3.5ex] \setuplist[section][alternative=d, style={\itx\setupinterlinespace}, separator={·}] \starttext \placecontent \dorecurse{5}{\chapter{Chapter}\dorecurse{10}{\section{Long Section Title}}} \stoptext I experience two issues. The first one is that I have no hay to get the sections that build a paragraph to have an adapted \setupinterlinespace. Right now the interline space is too high. And \setupinterlinespace from style doesn’t seem to work. The second issue is that I would like to get a separator between each section item in the table of contents. Am I missing something about separator? Could anyone explain what is wrong with the sample? Many thanks for your help, Pablo -- http://www.ousia.tk

Colored text's background, which the more "lcd-mkiv"?
by Elspeth McGullicuddy 17 Jan '14

17 Jan '14

[Colored text's background, which the more "lcd-mkiv"?; plus: Metapost variable "text" with "\definetextbackground"; plus: {\input ward}] Hi list, What would be the best, also the more up to date, way to put colored background behind text, that could cross page boundaries. I have found three ways of doing this: I would like to know which is best practice, and also the more "lua context document" fashion. 1- Using "\startbar[underbar] \input zapf \stopbar" as described p. 39 of "hybrid.pdf". 2- Using "\startMPpositionmethod{mpos:placeholder}", found in http://tex.stackexchange.com/questions/125162/rounded-box-around-placeholde… (Thanks to Aditya). A bit tricky, but perhaps the more versatile or universal? 3- Start with: "\definetextbackground" (same ref. as previous). %%%%%%%%%%%%% % About the third one I have had some difficulties, that might be thought of as a bug. % You might want and try the following example: it doesn't work if you have a MetaPost variable % whose name is "text". \starttext \startMPcode % numeric text; %% Try and uncomment this line drawarrow (0,0)--(3cm,1cm); \stopMPcode %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \definecolor [lightblue] [r=0.5, g=0.5, b=1] \definetextbackground [placeholder] [ location=text, background=color, backgroundcolor=lightblue, frame=on, corner=round, radius=0.8\lineheight, ] \placeholder{\input ward } % \placeholder{\input ward} %% Try and uncomment this line \stoptext % Local Variables: % mode: context % coding: utf-8 % End: Regards, Chris

A problem with itemize in columns - once again, now with an MWE
by Marcin Borkowski 17 Jan '14

17 Jan '14

Hi all, once again I have a problem with itemization in columns. This time, I finally managed to isolate the problem and prepare an MWE. The problem does not appear with Latin Modern fonts, but does with Pagella (I didn't test other fonts). It seems that the height of the square root sign is too high. \smash-ing helps, but I'd prefer not to have to \smash things manually. Can anything be done about this? (Note: I'm using the latest beta. In some earlier versions, \smash-ing didn't help, so it's not something of high priority for me now. But if it's something easy to fix, I'd be thankful.) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setupbodyfont[pagella] \starttext \startitemize[columns,two,packed]% with "packed", it's also wrong, but in another way \item abc \item $a^2$ \item xyz \item $\frac12$ \item foo \item bar \item baz \item $\sqrt{2}$% \smash-ing helps, but I'd prefer not to have to smash... \item asdf \item qwerty \stopitemize \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Best, -- Marcin Borkowski http://octd.wmi.amu.edu.pl/en/Marcin_Borkowski Adam Mickiewicz University

No bibliography in the output, depends on file name
by Nicola 17 Jan '14

17 Jan '14

Hi, maybe this is a known issue, but I couldn't find anything about it, so I'm reporting it. I'm writing a ConTeXt document called modern-c++.tex (in OS X 10.7.5). The content of the file is: \setupbibtex[database={modern-c++}, sort=author] \setuppublications[numbering=yes] \starttext \completepublications[criterium=all] \stoptext (Well, I haven't started to write my notes yet.) When typesetting it, though, no bibliography is printed (I've tried with Mark II/IV from MacTeX and with the latest Mark IV stable/beta). Renaming the .tex file to cplusplus.tex solves the problem (there is no need to rename the .bib file). Nicola

Problem with definelabel in recent standalone
by Rik Kabel 16 Jan '14

16 Jan '14

The following code fails with the current standalone (ConTeXt ver: 2014.01.14 22:36 MKIV beta fmt: 2014.1.14 int: english/english), but works with TL2013: \setuppapersize[A8][A8] \definelabel [Qb] [ text=, alternative=inright, way=bytext, headstyle=\ssxx, headcolor=darkgray, ] \starttext \Qb[labelname]This is some text. As in \in[labelname]. \stoptext The problem appears to be with the alternative= key, which I do not see in the wiki for \definelabel but take to be the MKIV equivalent of the location= key (as described on the wiki for \setupdescriptions and presented in numerous examples on the mailing list). The location= key appears to be ignored, although it does not otherwise fail, when used in this snippet. The example produces: The same code in TL2013 produces: Any clues about how to fix this will be greatefully accepted. -- Rik

Disable balancing of page bottoms
by Joshua Krämer 16 Jan '14

16 Jan '14

Dear list! Context (Mk IV) balances the bottoms of doublesided pages, even if I use \raggedbottom. How can I disable this? I'm thinking of something like "balance=no" for columns, only for pages. My problem is that I have a one-page float (rotated table) with the size of the textheight. The opposite page is not completely filled with text, which makes context crop the height of the page with the float, too, resulting in a shift of the float into the upper margin. That's why I want to disable balancing. Kind regards, Joshua Krämer

This works and it will very likely also work for my project. I'm afrraid though that I left out an important detail, namely that the ToC itself must be mentioned in the ToC. What I'm expected to emulate is the following: (with real pagenumbers of course) CONTENTS Acknowledgements i Abstract ii Contents iii List of Illusttratiions iv List of Tables v Abbreviations and Library sigla vi Preface vii Chapter 1 8 Chapter 2 etc. So my real question should have been: Is there a way to place the ToC in an unnumbered chapter, which should not be at the very beginning of the book? But you have suggested the answer already: Changing \title{Contents} to \prechapter{Contents} does just that. Clean solution for an, imho, odd request. Best regards, Robert Blackstone

Setting `before` option of chapter breaks header text
by Michael Scholtz 15 Jan '14

15 Jan '14

If chapter titles are styled using the `before` option, the header texts on each first page of the documents (body|back|appendix)part are incorrect, because chapter name and number are empty. (Tested with ConTeXt version 2013.05.28 00:36 and 2013.09.03 10:22) Is this a bug? (If not, is there any other way to set `before` without breaking the headers?)

Feature Request: Set Output Directory
by Thangalin 15 Jan '14

15 Jan '14

Hi, Summary: If the --result parameter includes a path then ConTeXt should assume that that directory is writable thus read/write its temporary flies at that location instead of the current working directory (CWD). Consider the following three accounts: - ConTeXt installation account (e.g., "context") - Web server account (e.g., "web") - Application account (e.g., "app") ConTeXt is run using the web server account. The web server's CWD is set to the application directory. For security reasons, the "web" account may not create files in the "app" account. When ConTeXt is called by the "web" account, the CWD is an "app" account subdirectory. This subdirectory contains scores of .tex input files that control various themes for the final rendered document. Many different users, through this web-based application, create different content .tex files. I would like to run context as the web user within the app directory, where the input .tex files are located; effectively, as the "web" account, this would look like: cd /home/app/public_html/book/context source /home/context/bin/context/tex/setuptex /home/context/bin/context/tex/texmf-linux-64/bin/context /home/web/users/1/book.tex --result=/home/web/users/1/book.pdf Since the "web" account cannot write to the "app" directory, this causes the following error: ! I can't write on file `book.log'. The following is also not possible as the "web" account: cd /home/web/users/1/ source /home/context/bin/context/tex/setuptex /home/context/bin/context/tex/texmf-linux-64/bin/context book.tex This fails because the book.tex file includes files that are in the "app" directory, which cannot be found. Since the "book.tex" file will be in a different directory for every user, a symbolic link in each book directory would probably resolve the issue, but that's a bit wasteful. I have updated TEXMFCACHE in texmfcnf.lua to point to /var/cache/context/texmf-cache/ (world-writable), but it didn't help. It seems that ConTeXt assumes write permissions to the current working directory, which is not a valid assumption. Thoughts? P.S. Also, the --result parameter should be listed in the --help page (or the --help page should list --all as a way to see all the options).

Difficulties with \startformula
by Elspeth McGullicuddy 14 Jan '14

14 Jan '14

Hi, 1- I put here a far too long example to show difficulties that I have with formulas in conjunction with framed: I haven't find a way to insert a formula (displaystyle, vertical mode), at the beginning of a \framed. 2- It might be related with this other thing: The last examples are about mouse text selection with Okular (haven't tried with another viewer): When I "mouse text select" elements of the formula, when the \startformula \stopformula in embeded in a \hbox, what is highlighted looks alright. Instead, when it's in "vertical mode", what is highlighted is very very large. It's probably not the purpose of pdf documents, but this select (and copy) feature is very convenient. This feature is rather impinged with this not so nice looking behavior. Also in these conditions Okular can't select the text precisely, but instead select a much wider area of text (one example here does this). 3- When embedded in \hbox (not vertical mode then), the height of "mouse text section" is alright is formula is 'x+y', but there is an error if the formula in instead '\int_a^b'. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \starttext \setupformulas[spacebefore=-1ex] \framed[width=5cm,align=yes]{% Hello } \framed[width=5cm,align=yes]{% Hello \startformula x+y \stopformula } \framed[width=5cm,align=yes]{% %Hello \startformula x+y \stopformula } \framed[width=5cm,align=yes]{% \vskip-1.3\baselineskip \startformula x+y \stopformula } \framed[width=5cm,align=yes]{% \hairline \startformula x+y \stopformula \hairline } \hairline \startformula x+y \stopformula \hairline \framed[align=yes]{% \type{\vrule \hrule \vbox $$}\\ \hbox{\vrule{\hsize=7cm\vbox{\hrule $$ x+y $$ \input{knuth} \hrule}}\vrule}} \framed[align=yes]{% trying to select the ``x'' in the next formula, select text [\type{he ``xhe \vbox x+ syste conyer and}]\\ \type{\vrule \hrule \vbox \startformula}\\ \hbox{\vrule{\hsize=7cm\vbox{\hrule \startformula x+y \stopformula \input{knuth} \hrule}}\vrule}} \framed[align=yes]{% \type{\framed \vbox \startformula}\\ \framed{% {\hsize=5cm\vbox{% \startformula x+y \stopformula \input{knuth} }}}} \framed[align=yes]{% \type{\framed $$}\\ \framed[align=yes,width=5cm]{% $$ x+y $$ \input{knuth} }} \startbuffer \hbox{\vrule\startformula \int_a^b x+y \stopformula} \stopbuffer \framed[align=yes]{% This line generates an error\\ \typebuffer} \framed[align=yes]{% When one ``text select'' with mouse with Okular, height of selection is correct.\\ \hbox{\vrule\startformula x+y \stopformula}} \framed[align=yes]{% When one ``text select'' with mouse with Okular, height of selection is much larger than expected.\\ \startformula x+y \stopformula} \stoptext %%%%%%%%%%%%%%%%%%%% Regards, Chris
