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

New chapters of Manual--Yay!
by john Culleton 30 Jan '12

30 Jan '12

I note with some joy that there are draft replacement chapters for the MANUAL. The site shows three such: Fonts, typography and page design. Are there more that I missed? I am printing them out with great haste :<) -- John Culleton Free list of books for self-publishers: http://wexfordpress.net/shortlist.html "Create Book Covers with Scribus" http://www.booklocker.com/books/4055.html

[***SPAM***] simplefonts generating slanted font?
by Pablo Rodríguez 30 Jan '12

30 Jan '12

Hi everyone, I wanted to show the difference between italic and slanted fonts, so I have this minimal example: \usemodule[simplefonts] \setmainfont[TeX Gyre Pagella][slantedfont=fakeslanted] \definefontfeature[fakeslanted][default][slant=.25] \starttext {\sl slanted} font \stoptext But I don't get the slanted font working. What am I doing wrong here? Thanks for your help, Pablo -- http://www.oudeis.tk

bug with headcommand=type in definedescription?
by Pablo Rodríguez 29 Jan '12

29 Jan '12

Hi there, I have the following sample that works with \type: \definedescription[abc][headcommand=\tfa] \starttext \abc{\type{\startext}} not working \stoptext But if I use the headcommand=type option: \definedescription[abc][headcommand=\type] \starttext \abc{\startext} not working \stoptext it gives an error. Am I doing something wrong or have I hit a bug? Thanks for your help, Pablo -- http://www.oudeis.tk

bug with setuplist alternative?
by Pablo Rodríguez 29 Jan '12

29 Jan '12

Hi there, in the following sample: \setuplist[chapter][alternative=g] \setuplist[section][alternative=d] \starttext \completecontent \chapter{chapter} \section{section} \chapter{chapter} \subsection{subsection} I get the second chapter on the same line as the section. I'm afraid this might be a bug. BTW, how can I get a table of contents with heading that doesn't contain subsections? The wiki only offers the option \placecontent[chapter,section], but I need the heading. Thanks for your help, Pablo -- http://www.oudeis.tk

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

Stretch option for fonts doesn’t work
by Wolfgang Schuster 28 Jan '12

28 Jan '12

Hi, the “stretch” option for \definefontfeature doesn’t work anymore for “slant” does work. \starttext \definefontfeature[slanted] [default][slant=.25] \definefontfeature[stretched][default][stretch=2] \start \definedfont[Serif*slanted at 20pt] \ruledhbox{Test!} \stop \start \definedfont[Serif*stretched at 20pt] \ruledhbox{Test!} \stop \stoptext Wolfgang

Gnuplot and the dollar sign
by Janne Junnila 28 Jan '12

28 Jan '12

Hi! I'm having trouble while trying to make the following work: \usemodule[gnuplot] \startGNUPLOTscript[distr_simple_1] plot "2_simple_1.out" using (0.01*floor($1/0.01)):(0.870456/100000/0.01) smooth frequency with boxes, (cos(2*x)*sin(0.5*x) + 1)*exp(-0.4*x) \stopGNUPLOTscript \useGNUPLOTgraphic[distr_simple_1] The problem seems to be that the single dollar sign gets interpreted as the start of a math environment. I tried to look through the source code to see how I could tell context to bypass checking for certain characters, but I couldn't figure it out. Thanks for any hints! Janne Junnila

LuaTeX Function Arguments Variables Parameters List ConTeXt Lua \startluacode
by Mathieu Dupont 27 Jan '12

27 Jan '12

Hi List, I am trying to program with Lua but there are concepts I must not understand, and the documentation is somewhat lacking. The only useful thing I could use is Hans' manual, thanks to him. If someone could help me just understanding the concept I must me missing in this simple example I would appreciate it. So here it is. Running the following code, variable "a" should not be modified by my function, and stay (1,2), but it does get modified and becomes (4,2) like the new variable "b" I am creating. What is wrong with my code ? Thank you for any hint ! Mathieu \starttext \startluacode function myFunc(arg) local var = arg var[1] = var[1] + 3 return var end local a = {1,2} context("a = \\{") context(a[1]) context(",\\;") context(a[2]) context("\\}\\par") context("\\blank") local b = myFunc(a) context("a = \\{") context(a[1]) context(",\\;") context(a[2]) context("\\}\\par") context("\\blank") context("b = \\{") context(b[1]) context(",\\;") context(b[2]) context("\\}\\par") \stopluacode \stoptext
