Algorithms in ConTeXt
by Patrick Gundlach 06 Oct '10

06 Oct '10

Hi, I'd like to ask yet another "LaTeX in ConTeXt" question. Is there something like the algorithm package? It can typeset pseudocode like in the attached graphic. I sort of like the rules on the left side that indicate the scope of the for/while/case statements. Patrick

question about \inouter cum suis
by Thomas A. Schmitz 06 Oct '10

06 Oct '10

Dear gang, consider the following: \setuppapersize[A6][A6] \setuplayout [width=middle, height=middle, backspace=3cm, margin=1.5cm, location=doublesided] \starttext This nation, \inouter{1}turning 100 years old, had no {\em Odyssey}, no St.~George slaying the dragon, no Prometheus. The emerging American genius for making a lot of money was a poor substitute for King Arthur and his knights (although the Horatio Alger myth of rags to riches was good for a lot of mileage). Without a mythology and set of ancient heroes to call its own, America had to manufacture its heroes. So the mythmaking machinery of nineteenth|-|century American media created a suitable heroic archetype in the cowboys of the Wild West. The image was of the undaunted cattle drivers living a life of reckless individualism, braving the elements, staving off brutal Indian \inouter{2}attacks. Or of heroic lawmen dueling with six|-|guns in the streets at high noon. This artificial Wild West became America's Iliad. This nation, turning 100 years old, had no {\em Odyssey}, no St.~George \inouter{3}slaying the dragon, no Prometheus. The emerging American genius for making a lot of money was a poor substitute for King Arthur and his knights (although the Horatio Alger myth of rags to riches was good for a lot of mileage). Without a mythology and set of ancient heroes to call its own, America had to manufacture its heroes. \stoptext The \inouter{2} is typeset in the INNER margin, both in mkiv and mkii. I assume that's because the paragraph it's in starts on an odd page. Is there any setup command to change this behavior? Or is this the expected behavior? I looked into page-mar.mkiv, but couldn't find anything... All best Thomas

placepublications does not place publications

Hi all, the following code works in mkii. It used to work in mkiv as well, but doesn't anymore with the latest beta (I can't tell at which version it stopped working, sorry). Maybe a side-effect of the new structure code? All best Thomas \startpublication[k=ackermanmyth,t=book, a={{Ackerman}},y=1991, n=34,s=Ack91] \author[]{Robert}[R.]{}{Ackerman} \pubyear{1991} \title{The Myth and Ritual School: J. G.

two buglets
by Thomas A. Schmitz 06 Oct '10

06 Oct '10

Hi all, working on a book project with index and bibliography, I discovered two small bugs (at least I think they are bugs): 1. index sorts uppercase letters after lowercase letters. Minimal example: \starttext \index{Aardvark}Aardvark \index{azygous}azygous \page \setupregister[index][n=1] \placeregister[index] \stoptext I would expect azygous to follow Aardvark, but it is sorted before. 2. (Maybe not a bug, but a somewhat unfriendly behavior): When a \cite command refers to a non-existent key and sort=bbl, ConTeXt bombs out with a lua error: ! LuaTeX error ...text/tex/texmf-context/tex/context/base/bibl-tra.lua:77: attempt to compare nil with number stack traceback: ...text/tex/texmf-context/tex/context/base/bibl-tra.lua:77: in function <...text/tex/texmf-context/tex/context/base/bibl-tra.lua:76> [C]: in function 'sort' ...text/tex/texmf-context/tex/context/base/bibl-tra.lua:84: in function 'flush' <main ctx instance>:1: in main chunk. \typesetpubslist ...hacks.flush("\@@pbsorttype ")} \doendoflist \dodoplacepublications ...sttrue \typesetpubslist \inpublistfalse \endgroup ... l.37 \placepublications[criterium=all] minimal example (the typo \cite[clarke199] instead of \cite[clarke1999a] is there on purpose to demonstrate the problem): \setuppublications[state=start, sorttype=bbl, refcommand=authornum, numbering=yes] \setuppublicationlist[samplesize={VSdK90},totalnumber=2] \startpublication[k=champion2004,t=book, a={{Champion}},y=2004, n=10,s=Cha04] \author[]{Craige~B.}[C.~B.]{}{Champion} \pubyear{2004} \title{Cultural Politics in Polybius's {\em Histories}} \city{Berkeley} \pubname{Univ. of California Pr.} \stoppublication \startpublication[k=clarke1999a,t=book, a={{Clarke}},y=1999b, n=9,s=Cla99b] \author[]{Katherine}[K.]{}{Clarke} \pubyear{1999\maybeyear{b}} \title{Between Geography and History: Hellenistic Constructions of the Roman World} \city{Oxford} \pubname{Oxford UP} \stoppublication \starttext \cite[champion2004] \cite[clarke199] \page \placepublications[criterium=all] \stoptext Could this error be handled more gracefully, i.e. intercepted?

footnotes when using RtL (Arabic)
by Talal Al-Azem 05 Oct '10

05 Oct '10

Dear all, Two quick questions regarding footnotes and Arabic: 1. How do I get a footnote rule/marker to go from right-to-left (i.e. to begin at the right margin instead of the left margin)? 2. I would like some of my footnote streams to run RtL for Arabic, and also for those footnotes to be in paragraph form (i.e. \setupnote[afootnote][paragraph=yes] ). But when I add this command, my footnote instead runs LtR, the letters get cut up (i.e. the Arabic script is not connected), and I lose my footnote marker to add insult to injury. How should I define a footnote stream to run RtL in paragraph form? Many thanks in advance. Kind regards, Talal p.s. Below is my attempt thus far, with the problem of defining paragraph=yes, and with the problem of the footnote rule/marker. Reference to what I should change in this example would be most helpful: ========================== %%% SETUP AREA %% PAGE SETUP \setuppapersize[A4][A4] \setuplayout[grid=on] \showgrid \setupinterlinespace[line=3.8ex] \setupindenting[yes,big] %% FONTS \usemodule[simplefonts] \setupsimplefonts[size=12pt] \definefontfeature[default] [default] [mode=node,script=arabic] \setmainfontfallback[Lotus Linotype] [scale=1.33,features=arabic,range={arabic,arabicsupplement}] %% PARAGRAPH DIRECTION & SPACING - ARABIC - ENGLISH \def\arabpar {\textdir TRT\pardir TRT} \automigrateinserts % to ensure that certain levels of footnotes show up (raw MKIV feature) %% FOOTNOTES \setupfootnotedefinition[location=serried] \definenote[afootnote][conversion=set 2] \setupnote[afootnote][paragraph=yes] %%% TEXT \starttext \input knuth \startbaselinecorrection\setupinterlinespace[line=5ex] \arabpar{ هذه رسالة جامعة مانعة ألفه الشيخ الفاضل النحرير هذه رسالة جامعة مانعة ألفه الشيخ الفاضل النحرير هذه رسالة جامعة مانعة ألفه الشيخ الفاضل النحرير هذه رسالة جامعة مانعة ألفه الشيخ الفاضل النحرير هذه رسالة جامعة مانعة ألفه الشيخ الفاضل النحرير هذه رسالة جامعة مانعة ألفه الشيخ الفاضل النحرير \afootnote{هذه فوتنوت.} هذه رسالة جامعة مانعة ألفه الشيخ ألفه الشيخ الفاضل النحرير هذه رسالة جامعة مانعة ألفه الشيخ الفاضل النحرير هذه رسالة جامعة مانعة ألفه الشيخ الفاضل النحرير هذه رسالة جامعة مانعة ألفه الشيخ الفاضل النحرير هذه رسالة جامعة مانعة } \stopbaselinecorrection Thus, I came to the conclusion that the designer\footnote{Such as Knuth himself.} of a new system must not only be the implementer and first large--scale user; the designer should also write the first user manual. The separation of any of these four components would have hurt TEX significantly. \stoptext ==========================

startdescription
by Patrick Gundlach 05 Oct '10

Hi, is \startdescription a valid command? I've found it in the reference section on the wiki (generated cont-en.xml) Or is it meant as a pattern/template for another command? Patrick

fitting page around content
by Michael Goerz 04 Oct '10

04 Oct '10

Hi Everyone! is there a way to tell ConTeXt to fit the page tightly around the content? In LaTeX, I can do this with \usepackage[active,tightpage]{preview} The purpose is to create a standalone tikz figure of potentially unknown size. Thanks, Michael

Line height for smaller fonts. (Migrating from LaTeX to ConTeXt:) forcing new line and new page
by Procházka Lukáš Ing. - Pontex s. r. o. 04 Oct '10

04 Oct '10

Hello, let's have the following example: --- \starttext \tt \input tufte \hairline \tfx \input tufte \hairline \tfxx \input tufte \stoptext --- When I look at the result, I see the smaller font the bigger "gap" between lines (or this may be taken as "line height" relative to letter height). As I would need to type many datafiles, it's important for me to reduce line height, even if readability of the text becomes a bit worse. Is it possible to achieve this anyhow? Another question: How to force new line and new page to start? - LaTeX provides \newline, \newpage\ linebreak and \pagebreak commands - see e.g. http://www.personal.ceu.hu/tex/breaking.htm. Does ConTeXt provide similar commands? Or how to achieve this? Regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

present state of critical editions with ConTeXt MKIV ?
by Talal Al-Azem 04 Oct '10

04 Oct '10

Dear all, My apologies for flooding the mailing list as I try to come up to speed quickly with some of the perhaps more arcane usages of ConTeXt over the weekend. I have come to understand that ConTeXt MKIV can indeed produce beautiful critical editions (including those of Arabic texts). I've spent some time scouring the mailing list and wiki with things related to critical editions and Arabic (from the early 2000's until now), including the developing CitTeXt project. However, I have some questions. From my (nascent) experiences and readings regarding critically editing texts, the following appear to be necessary tasks for any typesetting software used to produce critical texts [1] (I have placed an + next to those features which seem to already be implemented in MKIV, and a '?' next to those which I am unsure) : 1. Marginal line numbers + 2. Keying lemmas to linenumbers ? Footnote streams where the lemmas are referenced in connection with the line numbers (and thus not by puting a footnote reference number in the body of the text after the variant). I.e., functionality similar to ednotes or Ledmac in LaTeX. From what I've read, it seems this might remain the most problematic matter currently. 3. Formatting the lemma footnote streams in paragraph/block form OR in columnar form ? This mailing list provided direction to using \setupnote[footnote][n=x], where if x=0 makes the footnotes into a single paragraph, and if x=2 or more than 2 or more columns appear. I am unclear, due to my relative inexperience with ConTeXt, whether this is deemed robust enough as part of the solution of keying lemmas to linenumbers (#2 above). 4. Lemma abbreviations ? When the lemma is rather long, it should be displayed partially only preceding the note at the bottom of the page 5. Nested or overlapping lemmas ? 6. Cross references to lines ? 7. Line number switches + I.e. being able to turn line numbering on and off, restart, etc. 8. Multiple footnote streams + 9. Parallel typesetting ? I.e. It seems this was last recently discussed on this list in August 2010, and I assume it is naturally still in development, as these matters surely take time. Thus, the main issues seemingly remaining are related to lemmas. Issues number 2 to 5 are my main concern at the moment. Any advice on currently effecting these and other matters with a '?' after them (or being told that it is currently impossible) would be most appreciated. Alternatively, it would be nice just to know where things stand. Kind regards, Talal Al-Azem Oxford [1] Further discussion of these (and further) tasks can be quickly surveyed in Uwe Lück, "ednotes — critical edition typesetting with LATEX" (ednotugb.pdf, 2005) -- which discusses in section 2.1 the task(s) of digitally-produced critical editions.
