Various setuptolerance settings within a single document
by Jan Tosovsky 19 Feb '14

19 Feb '14

Dear All, I'd like to apply 'verystrict' tolerance as a default value, which would be overridden by less strict values in several specific paragraphs with tricky word combinations causing problems when hyphenating. But when \setuptolerance command is used multiple times, the last one seems to be active only from that place on. When settings is wrapped by \start \stop commands, it seems to be ignored: \start \setuptolerance[tolerant] %text \stop Is there any way how to achieve this or do I have to use the lowest required value for the whole document? Thanks, Jan

Re: [NTG-context] Indenting after floating image
by Thangalin 19 Feb '14

19 Feb '14

Hi Jan, A work-around: \setupexternalfigures[location=default] \setupindenting[yes,medium] \define[1]\PlaceFigure{ \startplacefigure[number=no, location={page}, title={}] \externalfigure[#1] \stopplacefigure \\ \vskip-1em } \starttext \input{ward} \PlaceFigure{cow} \input{ward} \stoptext The wiki states: \setupindenting does not take care of indenting after environments, such as ConTeXt's itemizes, enumerations, definitions, formulas and floats. The work-around forces the new line using \\, then immediately skips back a line.

mp: choose colors randomly from list
by Schmitz Thomas A. 19 Feb '14

19 Feb '14

Hi all, I would like to have mp choose a (transparent) color randomly from a predefined list. My naive approach was (let’s restrict it to three colors): \startuniqueMPgraphic{colortest} save mycolor ; color mycolor[] ; mycolor[1] := (0.07, 0.21, 0.65) ; mycolor[2] := (0.6, 0.6, 0.4) ; mycolor[3] := (0.5, 0.8, 0.5) ; path p ; p := unitsquare scaled 2cm ; for i=1 upto 3: fill p shifted (i*2.5cm, 0) withcolor transparent (1,0.3,mycolor[round(uniformdeviate(i))]) ; endfor ; \stopuniqueMPgraphic \starttext \uniqueMPgraphic{colortest} \stoptext Is there a better approach? The selection isn’t random enough for my taste :-) Sometimes, in my real document, I get black color, even though black isn’t in the list, so I suspect that mp doesn’t get a correct value for mycolor[round(uniformdeviate(i))]. And finally: how could I define the colors in a way that I could also use them outside of mp? Or do I have to copy-paste the definitions into \definecolor’s? All best Thomas

superscripted \circ slightly too low?
by Sanjoy Mahajan 19 Feb '14

19 Feb '14

The superscripted degree symbol in $10^\circ$ comes out slightly low. e.g. \starttext \placeformula\startformula 10^\circ \quad 10\mathstrut^\circ \stopformula \placeformula\startformula x^7\quad x\mathstrut^7 \stopformula \stoptext I'm not quite sure what's right, but my eye says that the $10\mathstrut^\circ$ looks better. (And now I worry that all my superscripts are too low, but that could be my just being a worry wart.) Is the slightly lower superscript positioning a conscious choice with MkIV math? Or maybe there's a magic parameter to adjust it? I made some tests with other tex engines. In tex, pdftex, and latex, it comes out higher (as if \mathstrut were there). In pdflatex, it comes out slightly low. I noticed this isssue because my asymptote figures had the higher positioning, whereas the main context document had the lower positioning (and asymptote was using latex to generate the labels). -- -Sanjoy <http://savelongwharfpark.org/> Save Long Wharf Park in Boston Harbor! <http://streetfightingmath.com/> Six reasoning tools to make hard problems easy.

\completecontent affects text height
by Thangalin 19 Feb '14

19 Feb '14

Hi, First question: 1. Save http://pastebin.com/raw.php?i=8DQNCcvC as setup.tex 2. Save http://pastebin.com/raw.php?i=KgcxCxGB as garlic.tex 3. Run: context garlic.tex 4. View page 3 of the PDF ( http://i.imgur.com/VLwssnl.png ) 5. Edit garlic.tex. 6. Remove \completecontent 7. Run: context garlic.tex 8. View page 3 of the PDF ( http://i.imgur.com/HVAoavQ.png ) The Table of Contents affects the column height in the body. The available height for the text body should be independent of \completecontent. The total height should be as shown in the second example, with or without the ToC. How can this be resolved? Second question: How would you remove the white space above each subsection title so that the title is aligned to the top of its column? Third question: How would you prevent widowing of subsection titles from their content? I tried "ntop=2" and "\setuptolerance[tolerant]", but neither affected the result. Thank you!

(If I had them at hand I would try.) Thank you Martin. I was not clear. I can run Debian and other *nix flavors on the chromebook by various methods and then have ConTeXt, but I would rather not 'dual boot.' What I am after is to have ConTeXt run 'natively,' if that is the right word/concept, on a chromebook core platform. From the chromebook shell I know I can run vim to edit files but I would like to compile them. (Viewing will be the next chapter!)

[Math in ConTeXt]
by Otared Kavian 18 Feb '14

18 Feb '14

Hi all, After a series of exchanges on the list, on the topic of how mathematics typesetting is and should be in ConTeXt, I am writing you this message to ask all those who use ConTeXt to typeset mathematics and who encounter various types of difficulties, or shortcomings, to send me their remarks, either on list or off list. I will check the problems with Aditya Mahajan and Mikael Sundqvist, and then submit feature requests or bug reports to Hans and Aditya who will try to fix the issues (I have asked these people about this, and they all agree…). In order to help me manage efficiently the task, please add the following tag [Math on ConTeXt] to the Subject field of your message. The issues which may be addressed are of the following categories: 1. Differences in the output of ConTeXt mkiv vs mkii (due to differences in engine) 2. Differences in the output of ConTeXt mkiv vs LuaLaTeX + Opentype math fonts (due to differences in macro package) 3. Differences in the output of ConTeXt mkiv vs PDFLaTeX + AMSMath (due to differences in expectation) 4. Bug reports (regarding commands of plain TeX missing in ConTeXt, the position of math accents, etc…) Indeed some of the issues may have their origin in the fonts (therefore not easy to fix thouroughly), but others may be fixed once the expectations are clearly expressed. As usual, please give minimal examples imbedded in \starttext ……… \stoptext so that we can test the issue you are reporting. Thanks for your attention and cooperation, Best regards: OK

How to center a \placefloat?
by Marcin Borkowski 18 Feb '14

18 Feb '14

Hi list, I'd like to have a figure (by means of \placefigure) centered horizontally. Currently, I'm doing \placefigure[bottom,none,middle]{}{% \hbox to\textwidth{\hfil\externalfigure[logo-2-t][height=1.5cm]\hfil}} Is there a better way? If yes, how to do this? TIA, -- Marcin Borkowski http://octd.wmi.amu.edu.pl/en/Marcin_Borkowski Adam Mickiewicz University
