Do you suggest me to publish an article about the terminal in arXiv, to get at least some citations by the time when I need to submit my thesis? :P But no, I don't have it. I could try to create one though, but I'm not even sure what the webpage should be. Many scientific programs just ask to cite their first article in some scientific journal if one uses the software, but I neither have an article nor homepage apart from that (still outdated) wiki page. There is some additional documentation on https://github.com/mojca/context-gnuplot/tree/master/texmf/doc/context/thir… (possibly also in minimals, but I'm not sure when I last synced the version), but even that is outdated now since they required from me to strip down terminal options parsing code.

However if the Lua code did interpret the number into an internal format it would enable other things like normalisation to scientific or engineering form, etc. However the internal format would have to support arbitrarily long numbers and exponents ... Lua's built-in internal number format (a double precision float, I think) would not do, so there would be a bit of coding involved. Robin

MetaFun: MetaPost example works with `mpost` but not embedded in ConTeXt: `! Redundant equation.`
by Paul Menzel 12 Dec '11

12 Dec '11

Dear ConTeXt folks, looking for graphics example and therefore searching the list I found the answer from David Arnold in the ntg-context list thread »OT: looking for metapost/fun examples« [1]. It is for plain MetaPost and works fine with `mpost` after making sure to remove the line breaks inserted by the mail program. I then copied it into `\{start,stop}useMPgraphic`, removed the `end ;` and `{begin,end}fig` and replaced `{e,b}tex` by `textext()` but still get the following error. ! terminal: ! Redundant equation. <to be read again> ; <*> ...500; dt:=(tstop-tstart)/N; (b-a)*ux=1.75in; (d-c)*uy=1.75in; q=(a,c)-... !

wider right margin when it shouldn't be
by Pablo Rodríguez 11 Dec '11

11 Dec '11

Hi there, compiling this document: \setuppapersize[A4] \setuppagenumbering[alternative=singlesided,location=middle] \starttext \showsetups \dorecurse{4}{\input dawkins \par \input knuth \par} \stoptext I should get the exact same length for left and right margin (defining margin as the total distance from the page edge to the text body edge [sorry, it isn't as accurate as it should, but I would like to avoid misunderstandings]). Setups show also that margin width and distance are equal for both sides. What I see on my laptop (and what I have seen on the printed version) is that the right margin is wider than the left one. Is there something wrong or which is the measure I'm missing? Thanks for your help, Pablo -- http://www.ousia.tk

orphan and widow lines
by Pablo Rodríguez 11 Dec '11

11 Dec '11

Hi there, I have been using ConTeXt for some months and one of the things I cannot control is orphan or widow lines appearing in my documents. Isn't there a general method to avoid them? (This should set ragged bottoms, but I'd rather have ragged bottoms than orphan or widow lines.) Thanks for your help, Pablo -- http://www.ousia.tk

bug with \setuplayout[setups=*strict]?
by Pablo Rodríguez 11 Dec '11

11 Dec '11

Hi there, I read a previous message on this list form Wolgang that \setuplayout[setups=*strict] is the ConTeXt way to avoid orphan and widow lines. I have tried that before checking that \widowpenalty=10000\clubpenalty=10000\raggedbottom doesn't change anything on my documents. The problem with the first code is that it breaks some pages in clearly wrong places (it breaks the page on the seventh line of a A4 page). I don't know how I could provide an example, since the document is a personal document that I cannot share with third parties. Is there no other way to avoid orphan and widow lines? I need it urgently. Thanks for your help, Pablo -- http://www.ousia.tk

∫ is not displayed correctly compared to $\int$.
by Paul Menzel 11 Dec '11

11 Dec '11

Dear ConTeXt folks, using ConTeXt ver: 2011.05.18 22:26 MKIV fmt: 2011.5.27 int: english/english the following example produces different integral signs. --- minimal example --- \starttext Using the NEO keyboard layout several math symbols can be inserted directly like $∫$ or $∩$. But $\int$ and $∫$ look differently. \stoptext --- minimal example --- Please find all files attached. Thanks, Paul [1] http://neo-layout.org/

Number formatting in \unit
by Robin.Kirkham＠csiro.au 11 Dec '11

11 Dec '11

All, I have put together some suggestions to extend the number formatting capability in \unit, particularly for scientific and engineering purposes, including basic support for tolerances and uncertainties. It is a bit long, so source is attached and a PDF is at http://dl.dropbox.com/u/36891398/units6.pdf Of course, this is just my opinion, so I welcome any feedback from the list. Best, Robin
