Does the R-Module work (or how)?

Dear List, does the R module work? To be more specific "m-r.tex". I tried to run the test named as "Johan's test file" and got the result below -------------------- !

Vertically Aligning inmargin Text to Figure
by Malte Stien 18 Jun '13

18 Jun '13

Hi, I need to associate a bit of text with a figure in a book. The text is not---and cannot be---the figure caption (it's providing some explanation with respect to some labels in the figure). I have tried the following based on some other post on the mailing list: \definepapersize[eightsquare][width=8in, height=8in] \setuppapersize[eightsquare] \setuplayout[ location=doublesided, marking=on, backspace=43mm, leftmargin=18mm, leftmargindistance=4mm, rightmargin=35mm, rightmargindistance=4mm, rightedgewidth=6mm, topspace=12mm, header=15mm, footer=15mm, height=179mm, width=115mm ] \starttext \startplacefigure[location=force, title={First dummy caption}] \inmargin{First margin dummy} \externalfigure[dummy][width=115mm] \stopplacefigure \stoptext However, that results in the text being down the bottom of the figure. I need the text to be vertically aligned with the top of the figure. I have attached the resulting PDF for illustration purposes (is that okay on this mailing list? It's very small). Any hints would be much appreciated. Thank you, Malte. -- “The Electric Monk was a labour-saving device, like a dishwasher or a video recorder...

(forw) Fraktur fonts
by Rudolf Bahr 17 Jun '13

17 Jun '13

----- Forwarded message from Rudolf Bahr <quasi(a)quasi.de> ----- From: Rudolf Bahr <quasi(a)quasi.de> Reply-To: ntg-context(a)ntg.nl To: ntg-context(a)ntg.nl Subject: Fraktur fonts Date: Wed, 12 Jun 2013 11:28:12 +0200 Message-ID: <20130612092603.GA1090@mini> User-Agent: Mutt/1.5.21 (2010-09-15) Hello list members, an only-a-few-days-fan of Context writes to you for the first time. I'm pleased to have found a program closer to TeX and younger than LaTeX. In the last years I used LaTeX for a bigger family project with good success, but experienced some difficulties in arranging minipages containing changing text and pictures especially in series letters. So I'm trying to do that using Context. Of course I cannot change hundreds of files from LaTeX to Context, but newer tasks I'd like to do in Context. There is a first question I have concerning Fraktur fonts which I'd like to use typesetting a poem: I found a 2-mail-discussion in your 2002-archiv concerning those fonts. But I have to admit that I don't understand what is written there. So, I tried simply \definefont[Gedichtfont][Fraktur] \Gedichtfont{... poem ...} both with "context" and "texexec", but I don't achieve the desired result. "texexec" displays a font somehow similar to Fraktur, but not a very nice one and much to broad; and it seems to have no different "s" (one inner-word and one word-end or syllable-end "s") as needed in Fraktur. And, my "texexec" doesn't know anything about umlauts and sharp s. Whereas my "context" (translating the same program), dosn't know Fraktur, but knows umlauts. So I'm always using both of them, enjoying the partial success of both, though I read somewhere, it should be better using "texexec". Well, a very nice Fraktur font is Yannis Haralambous' "yfrak" in his "yfont" series, the nicest one I've found until now. Could you please help me to formulate the correct commands to use a "nice" Fraktur font, be it "yfrak" or another one? But please remember, Context is still rather confusing to me. So, it should be simple enough. Best regards, Ruhmwolf ----- End forwarded message -----

two simple questions on presentations
by Pablo Rodríguez 17 Jun '13

17 Jun '13

Dear list, sorry for asking the following questions, but I wasn't able to find the answers on the reference manual, the wiki or the command list. I wanted to make some cards (and I'm interested also in this features for presentations) that have the following features: -Everything in the cards is centered both horizontally and vertically. \setupalign[lohi] doesn't work outside frames or similar and \setupalign[middle] centers only horizontally. -Page background colors that can be changed from a given point to the rest of the document or the next page background color change. \setupbackgrounds[page][background=color, backgroundcolor=blue] sets the background color for all pages. How could I get both features? Many thanks for your help, Pablo -- http://www.ousia.tk

Halt ConTeXt on Certain Warnings/Errors
by Malte Stien 17 Jun '13

17 Jun '13

Hi all, Is there are way I can have ConTeXt halt on particular warnings or errors? In particular, I like it to spit the dummy when it finds an unknown reference. Otherwise, I end up with the unknown references in the document that I sometimes don't find until much later. At the moment I grep for "reference" when I run context, as in context *.tex | grep reference ...but I thought there might be some more elegant way to do this.

NTG-context] How to hack the lua files
by Lance Larsen 17 Jun '13

17 Jun '13

Hans, Thankyou for your suggestion of using the \usereferences tag to reference formulas in another document. This is a good solution. However the example below doesn't give usable results because the references to the external formula output by test2.tex does not include the chapter number: test1.tex: ------------- \starttext \chapter{Chapter 1} \placeformula[one] \startformula x = y \stopformula \placeformula[two] \startformula y = z \stopformula \chapter{Chapter 2} \placeformula[three] \startformula z = x \stopformula \stoptext test2.tex: -------------- \usereferences[test1.tex] \starttext \in{formula}[test1.tex::one] \in{formula}[test1.tex::two] \in{formula}[test1.tex::three] \stoptext In the output of test1.tex, the formulas are labeled (1.1), (1.2), and (2.1). In the output of test2.tex the references are labeled 'formula 1', 'formula 2', and 'formula 1' (i.e. the section number is not included). Using the \usereferences tag works if I label formulas 'bytext' rather than by 'bysection' and turn off chapter prefixes in test1.tex using the following at the start of the document: \setupformulae[way=bytext,prefixsegments=None] I would really prefer to maintain numbering by section, but to do this, I need test2.tex to show external references in the same way as test1.tex (by including the section number in front of the equation number). Is there a way to do this at present? If not, labeling formulas 'bytext' will work for now even if it isn't ideal. -Lance Larsen On 6/7/2013 4:01 PM, Lance Larsen wrote: > luigi, > > When I started exploring how to map equation references (eq:name) to > equation numbers (4.2), I noticed that the 'tuc' file included the equation > reference (eq:name), but I was not able to identify anywhere where it > indicates the actual equation label specified in the document.

orphans and widows in poems
by Pablo Rodríguez 17 Jun '13

17 Jun '13

Dear list, I have a document that contains a long poem and although it contains the following code: \setuplayout[setups=*lessstrict] \startsetups[*lessstrict] \setup[reset] \widowpenalty=10000 \clubpenalty=10000 \brokenpenalty=10000 \stopsetups I'm afraid that I get widow lines in the lines environment. Is there no way to avoid orphans and widows in the lines environment? Many thanks for your help, Pablo -- http://www.ousia.tk

I am now using xtable to have an XMLish document to store a table. How I can embed ConTeXt code like $\Delta{}N_{\text{test}}$ in the external XML file file with the table? In other words, having mathematical notiation in the table header? I tried various things such as: \expanded{\xmlflush{#1}}

Output from Context standalone (actual version) has wrong utf-8 encoding
by Christian Prim 17 Jun '13

17 Jun '13

Hi list rendering a very easy formula with greek text in it produces a pdf-document that has not a valid utf-8 string. I use evince for displaying pdfs under ubuntu linux. The document appears correctly on the screen but stops printing after a greek letter in a formula. The error-report says: Internal Error: cairo context error: input string not valid UTF-8 The same document compiled in live.contextgarden.net doesn't produce a mistake and can be printed with evince. I can still print the document correctly using 'lpr name.pdf', so it's not a big problem for me. But I don't know if that could be a problem for someone else. Test-Document: \starttext $3\omega$ \stoptext Tell me, what I can do to help. Thanks Christian
