Question marks in bibliography entries [solved]
by Pontus Lurcock 05 Feb '12

05 Feb '12

Hello all, I am presenting an answer rather than a question, for a change. (Though as usual it's about bibliographies.) Last November, Renald Buter posted a question about how to suppress the full stop which follows a publication title in the case where the publication title itself ends in a question mark -- this produces entries like Authorname, A. (1990) A rhetorical question?. Journal of etc. etc. which doesn't look nice. At the time I gave some untested suggestions. Now (due to a sharp-eyed thesis examiner) I've actually had to test and implement a solution. For anyone else with this problem, I've written it up at http://wiki.contextgarden.net/Question_marks_in_bibliography_entries . As usual with BibTeX-y things, it's a hack, but it does the job. I hope this will save time and effort for somebody. Pont

Details.pdf -- how current?
by Peter Park Nelson 04 Feb '12

04 Feb '12

Given that ConTeXt has been under development for 10 years since the Details manual was written, can someone tell me how much of the material in is still applicable to recent betas? The examples use parameters that are not documented on the wiki, such as "inner" (\setupfloat) in this example on p.61: \setupfloat [edgefigure] [default={inner,height,high,low,none}, maxwidth=4cm, margin=\strutdepth] -- Peter Park Nelson peter.park.nelson(a)gmail.com

A bug in latin modern fonts?
by Janne Junnila 04 Feb '12

04 Feb '12

Hi! The following example seems to have some troubles with the latin modern fonts: \starttext The function $f \colon \reals \to \reals$ is given by $x \mapsto x - 3$. \stoptext The colon is printed fine, but the blackboard bold Rs don't look correct. The \mapsto symbol is missing and there's a hyphen instead of minus. Are others having the same issue? I tried to do a fresh install, but the problem persisted. There were some messages like fonts > otf loading > skipping cyclic reference U+00028 in math variant U+00028 during compiling. I don't know if they are related to the problem. Thanks, Janne Junnila

\definelayout[first] does not yield to default layout on page 2
by Peter Park Nelson 04 Feb '12

04 Feb '12

First-page layout is an issue that I have asked about before, but maybe I am doing something wrong. Here is my question in an earlier thread: http://archive.contextgarden.net/message/20111228.041922.c60f9cd5.en.html . I want to define a layout for the first page of my document with different header and footer formatting -- specifically, no header and a large footer to hold publication information. Based on examples on Contextgarden and this list, I think my code below is correct. However, the first page formatting is continued on all pages of the document. The effect is the same when using \definelayout[first] and \definelayout[1]. %%------------------------------------------------------------------- setuppapersize[letter][letter] \setupindenting[yes, medium] \setuplayout [width=middle, backspace=15mm, topspace=10mm, height=254mm, header=10mm, % normal header headerdistance=5mm, footer=5mm, footerdistance=5mm, grid=yes] \definelayout [first] [width=middle, backspace=15mm, topspace=10mm, height=254mm, header=0mm, % no header headerdistance=0mm, footer=25mm, % big footer footerdistance=5mm, grid=yes] \definecolumnset[body][n=2,balancing=yes] \setupheadertexts [This is a header] [pagenumber] [pagenumber] [Some text] \setupfootertexts [footer] [footer] [footer] [footer] \starttext \startcolumnset[body] \dorecurse{20}{\input tufte\par} \stopcolumnset \stoptext %%--------------------------------------------------------------- Thanks, -- Peter Park Nelson peter.park.nelson(a)gmail.com

Set a block of content at minimum distance from top of page?
by Peter Park Nelson 04 Feb '12

04 Feb '12

Hi ConTeXt list, I have a document with a graphic (logo) in the upper right corner (positioned on a layer and placed as a background). To the left of this graphic are several text elements (Title, Author List, etc.) that don't go all the way across the page. (Currently I have wrapped them in \startnarrower...\stopnarrower -- is there a better way?) But this is followed by an Abstract paragraph that uses the full width of the page. I would like to ensure that the full-width text never starts high enough on the page that it encroaches on the upper-right-corner graphic. So, I'm looking for a way to protect the graphic, or to force the Abstract to start a minimum distance from the top of the page. The Abstract can be forced down the page if necessary by manually inserting a \godown[] command before it, but I would prefer a programmatic solution. Floating the graphic and wrapping text around it does not seem like a good option, because I want to ensure that its position is absolute and it never moves. Also, the Abstract needs to be full-width throughout, so I need to force it to start after the graphic rather than partially wrapping it. Any suggestions appreciated...

You're right. I made a simple error in modifying strc-lst.lua. I typed 1 (numeral) rather than l (letter). Now it all works as you said it should. Thanks!

Bibliography problem
by Pontus Lurcock 02 Feb '12

02 Feb '12

Hello, Here's a long-standing problem I have with BibTeX databases in ConTeXt Mk IV (I'm currently using version 2011.10.01). If there are multiple publications with the same authors and year, they get suffixes a, b, etc. as is usually expected in bibliographies. Unfortunately these suffixes appear even if only one of the works is actually cited. Minimal example: ==> test.bib <== @book{book2, title = {The second book}, author = {Ann Author}, year = {2000}, } @book{book1, title = {The first book}, author = {Ann Author}, year = {2000}, } ==> test.tex <== \setupbibtex[database={test},sort=author] \setuppublications[sorttype=bbl,refcommand=authoryear] \starttext % \cite[book1] % uncomment to demonstrate ordering problem \cite[book2] \placepublications[criterium=text] \stoptext This gives a citation of Author (2000a) despite there being no Author (2000b). A related problem is that even when both suffixes are used, they are applied in the order of the original .bib file rather than in the order of the typeset bibliography. So if \cite[book1] is uncommented in the above example, the bibliography contains Author (2000b) followed by Author (2000a). I'm guessing that problem is that the whole BibTeX file is processed into ConTeXt's \startpublication...stoppublication syntax, not just the cited works. I can't see a way around the this, other than creating a custom .bib file for each document with the problematic entries removed or re-ordered. Does anyone have any suggestions? Thanks, Pont

Dubious "checksum mismatch" message on log file

Is it a "bug" in font system of context? P.S. There is a thread on tex-live mailing list about "checksum mismatch", I took a little investigation that reveals the source of problem: 'luaotfload', adaptation of context font system for latex world. As you can see from "ex8.tex", current context have the same behaviour. I'm not fully sure if it is save to ignore this message (I read briefly about vf fonts here: http://www.tex.ac.uk/tex-archive/help/virtual-fonts.knuth) but as both pdftex and luatex engines give nothing on "plain" example I want to report about this issue. -- WBR, Vladimir Lomov -- That's the thing about people who think they hate computers.

Problem with Lua processing UTF8 substrings

Hello ConTeXist, I want to use Lua to write characters (substrings) from a string, but I get an error message: ! String contains an invalid utf-8 sequence. I tried various Lua functions for working with UTF8 strings for example: string.subutf8(string, start[,end]) for i, char in str:nextutf8(orig_pos) string.lenutf8(string), but without success. Can you please someone help? Thanks Jaroslav Hajtmar Here is my minimal example: \def\mymacro#1{\ctxlua{for i=1, string.len('#1') do context(string.sub('#1',i,i)..", ") end}} \starttext %\mymacro{šěřěžřýčřčžáýčý} % Here is a problem \mymacro{asdfghjklqwertt} % Here is all OK \stoptext

Hi all, when updating some module documentation I came across this one: ································································· \startpublication [ k=mt, t=book, a={Bodoni}, y=1818, n=1, s={Manuale}, ] \author[]{Giambattista}[]{}{Bodoni} \pubyear{1818} \title{Manuale Tipografico, 2~vols} \city{Parma} \stoppublication \starttext foo \cite[authoryear][mt] bar \stoptext ································································· This definitely works with the beta from 2011-11-04, but not with the one from 2012.01.25. Has there been a change? Regards Philipp

setupheads[sectionnumber=no] (and retrocompatibility issue)
by Marco Pessotto 01 Feb '12

01 Feb '12

Hello there. See this minimal example. %% cut here \setupheads[sectionnumber=no] \starttext \placecontent \chapter{Chapter} \section{Section} \subsection{Subsection} \stoptext %% end With version: 2012.01.25 14:16 the numbers are there (and if I tweak the ToC listing I get a mess). With the current (2011.05.18 22:26) everything is fine. Using [number=no] with the beta the numbers disapper, while the current prints out the numer (and again a mess in the ToC). http://wiki.contextgarden.net/Reference/en/setupheads says that the right command is sectionnumber, but it's obviously outdated. Thanks in advance for the attention. Cheers -- Marco

GSUB init, medi, fina and .fea file

Hi there, I have the following OpenType feature archive (intended to use diferent forms for initial and medial/final beta, theta and phi): languagesystem DFLT dflt ; feature init { sub uni03D0 by uni03B2 ; sub uni03B8 by uni03D1 ; sub uni03D5 by uni03C6 ; } init ; feature medi { sub uni03B2 by uni03D0 ; sub uni03D1 by uni03B8 ; sub uni03C6 by uni03D5 ; } medi ; feature fina { sub uni03B2 by uni03D0 ; sub uni03D1 by uni03B8 ; sub uni03C6 by uni03D5 ; } fina ; I use it with this file: \usemodule[simplefonts] \definefontfeature[default][default][script=latn,init=yes,medi=yes,fina=yes,featurefile={greeksubs.fea}] \setmainfont[Theano Didot] \starttext βάρβαρος φιλοσοφία θεάσασθαι \stoptext But for some strange reason, even with this font I don't get the initial theta (uni03D1) and middle . If I change the font, add \agr to the text, change the script or remove Latin for the default font feature, GSUB no longer work. As far as I understand, the default rules should be independent from script, language and font. What am I missing here or doing simply wrong? Many thanks for your help, Pablo -- http://www.oudeis.tk

Problem Citing a Definition
by Kip Warner 01 Feb '12

01 Feb '12

Hey list, I am trying to cite a definition typeset with a \startdefinition[definition:foo] and \stopdefinition pair. I am doing this by using a \in{definition}[definition:foo]. That works, but in the text I just see linkable text "definition". I'd like it to be more descriptive of the physical location in the book, e.g. "foo in section 10.2". It was my impression according to the manual that it was suppose to already do that, or am I not using \in correctly? -- Kip Warner -- Software Engineer OpenPGP encrypted/signed mail preferred http://www.thevertigo.com

What’s your favorite command?
by Wolfgang Schuster 31 Jan '12

31 Jan '12

Hi all, to bring some traffic to the list I have a question where I hope even non regulars send a answer. The ConTeXt package is huge and provides dozen of commands but I guess many have *one* favorite command (maybe also functionality). As I started this thread I’ll present my favorite command which is \donothing, it is a internal command and only a synonym for \empty but it’s one reason why I prefer ConTeXt’s coding style (especially with the recent changes in MkIV) over the unreadable LaTeX code.

Re: [NTG-context] What?s your favorite command?
by S Barmeier 31 Jan '12

31 Jan '12

My favourite command chooses to remain anonymous for now. All it has agreed to disclose about itself is that it gives total control over margin notes, in particular placement & page breaking... In case an ID is required for attendance, I think I'll go for \setCJKmainfont, representing Unicode support and simple way of choosing fonts across scripts, which is a "deal maker" for me... Thank you Hans and Wolfgang =) Severin

Canonical way to escape the square brackets?
by Marco Pessotto 28 Jan '12

28 Jan '12

Dear list, I swear I searched the internet, but I guess the terms are too generic. The question is: is there a safe way to escape the square brackets, preventing them to be eaten by the previous command? For example: \item [this should be in brackets] My solution is: \define\leftsquarebracket{[} \define\rightsquarebracket{]} \item \leftsquarebracket this should be in brackets\rightsquarebracket I'm pretty sure there is already a built-in command for them, so I'm asking the list. Thanks in advance. Best regards -- Marco

Scaling of math glyphs
by Aditya Mahajan 28 Jan '12

28 Jan '12

Hi, In my opinion, the size of the \sum in Cambria in display style is too large. I know that this is a design decision on part of Cambria designers, but I am wondering if I can scale the glyph down. I made a local copy of cambria-math.lfg and changed FixDisplayOperatorMinHeight to local function FixDisplayOperatorMinHeight(value,target,original) table.print(target) local o = original.mathparameters.DisplayOperatorMinHeight if o < 2240 then return 2240.0 * target.parameters.factor else return 0.8 * value -- already scaled end end This works, but as expected, it scales down both \sum and \int. Is it possible to just change the height of \sum? Thanks, Aditya

LuaTeX Function Arguments Variables Parameters List ConTeXt Lua \startluacode

xtables: stretch a single column
by Andreas Schneider 27 Jan '12

27 Jan '12

Hi, xtables offers option=stretch to stretch the whole table evenly. Is there also a way (without manually calculating the width) to stretch the whole table using a given column? Short use case: I have a table with three columns. Column 1 has an external figure, column 3 a variable length (but still short) text/string and column 2 has either no text at all or maybe a longer phrase. Columns 1 and 3 should be auto-sized (i.e as small as possible) while column 2 should be as width as necessary, to make the whole table fit perfectly onto the page (width-wise; height doesn't matter for now). I think with natural tables it was possible to set width=broad for a certain column. Is something like that possible with xtables as well? Thanks! -- Best Regards, Andreas

"overscored" or "overlined" text … (or whatever it should be called)
by Robert Blackstone 27 Jan '12

27 Jan '12

Dear all, I am trying to reproduce with ConTeXt an old french text that contains numerous abbreviations, mostly of two types: - words cut off by means of a "period", with the last letter of the complete word as a superscript above the period. - "overscores" --either for single characters, for instance in words with double consonances, like "comme". One of these is sometimes omitted and replaced by an "overscore" on the previous vowel -- or on an entire abbreviation, such as "coe" for "comme" and "nre" for "notre"; they become coe and nre overscored. Now I would like to reproduce these as closely as possible. For the "period + superscript letter" I found a solution: \lohi[]{\cdot}{t} (for superscript t), nearly perfect. The only imperfection I can see is that the dot sits slightly below the baseline. Is there a way to get it on the baseline? The overscore on a single character presents no problem. For an overscore on a complete word I have not found a solution. Three individual overscores on a three-letter word give a broken line; I do not know how to merge the three line components. (Incidentally, this hack does not work with mkiv) The other solution I have tried is to put the word in a frame with a top-frame only. But this way the word (abbreviation) hangs underneath the base-line. Using \inframed instead of \framed makes no difference. There appears not to be something like \setupinframed. I have attached an example. Thanks in advance for any help. Regards, Robert Blackstone

\externalfigure and file size
by Kip Warner 25 Jan '12

25 Jan '12

Hey list, I have a number of \externalfigure commands to typeset some svg images. This is often handy to have them vectorized because it allows for the user to zoom in on diagrams of great detail. In other situations, I find that for images that are not so important, they would benefit from ConTeXt rasterizing them when they are imported. The reason for this is I find some vector images get enormously bloated when they are typeset. As an example, I have a Logo.svg of only 6.8 KB. The m_k_i_v_Logo.pdf intermediate ConTeXt generates is nearly a megabyte in size. Why? I have no idea, as they both appear to be the same image with the same gausian blur. Is there a flag I can pass certain instances of \externalfigure that tells the image processing backend that a simple rasterized version of the figure is fine? Or is there a better approach? I don't want to pre-convert all of these images to raster formats. -- Kip Warner -- Software Engineer OpenPGP encrypted/signed mail preferred http://www.thevertigo.com
