The spaces in front of the lines are not taken into account for the two defined macros. What to do that \obeyspaces is also valid for these ones? \def\TextWithSpaces{\bgroup\obeyspaces\doTextWithSpaces} \def\FramedTextWithSpaces{\framed\bgroup\obeyspaces\doTextWithSpaces} \def\doTextWithSpaces#1{#1\egroup} starttext A gap from here to here!\par \TextWithSpaces{ A gap from here to here!} \framed{ A gap from here to here!}\par \FramedTextWithSpaces{ A gap from here to here!} \stoptext current minimal Herbert

TeX: Macro definition
by Procházka Lukáš Ing. - Pontex s. r. o. 07 Apr '11

07 Apr '11

Hello, how to define a macro to take the new-line character as end-of-parameter? The following macro: \def\T#1\par{#1} takes everything until \par (or empty line as it equals \par primitive) as #1, so the following is valid: \T abc def\par \T abc \T def (#1 becomes: "abc def", "abc" and "def".) How to define the same macro to accept end-of-line as end-of-parameter? I tried (although I'm aware this may not lead to the goal): \def\T#1^^M{#1} or \def\T#1\crlf{#1} to allow writing: \T abc def \T abc \T def So how to define the macro? Thanks in advance.

>> You need “location=middle” for the *inner* frames. I'm so sure that I've tried that already, anyhow. It works as expected, so thanks! Adam

frames within frame
by Reviczky, Adam 06 Apr '11

06 Apr '11

Hi If I have two frames within one frame, how can I vertically align the first (well, or both) framed to top or middle. Here's a minimal example: \starttext \framed[strut=no,height=fit,framecolor=green,background=screen,backgroundscreen=.80] {\framed[height=fit,width=100pt,background=screen,backgroundscreen=.90,frame=on,autowidth=force,align=middle]{first box wants to be on top/middle} \framed[offset=none,height=100pt,width=100pt,background=screen,backgroundscreen=.90,frame=on]{second box}} \stoptext So here the second framed defines the hight, and the first framed is on the bottom of the "big outer" frame. All I want is to have the first box on top or middle respectively. I've tried location, but that didn't work. Adam

Re: [NTG-context] Position of MetaPost graphics
by Tim Steenvoorden 06 Apr '11

06 Apr '11

Thanks Peter! You are right it is easier to draw both the wave and the line in Metapost. And the dx=-\cutspace is just what I needed for left pages! I striped the frames out of the code and placed just the graphics in the layer with a reuseMPgraphic. Also, I pulled out the definition of the wave into a MPinclusions. I have to do LoadPageState in each graphic though. %\showframe \setuppapersize[A5][A5] \setuppagenumbering[alternative=doublesided] \startMPinclusions numeric periods, width; path wave; periods := 3 + 1/4; width := periods * 2*pi; wave := origin for x=0 step 0.1 until width: .. (x,x*sin(x)) endfor; \stopMPinclusions \startreusableMPgraphic{rightwave} LoadPageState; pickup pencircle scaled 1pt; draw origin -- (TextWidth,0) -- wave xscaled (CutSpace/width) yscaled (LineHeight/width) shifted (TextWidth,0); %setbounds currentpicture to unitsquare xscaled (TextWidth+CutSpace); \stopreusableMPgraphic \startreusableMPgraphic{leftwave} LoadPageState; pickup pencircle scaled 1pt; draw reverse wave xscaled (-1*CutSpace/width) yscaled (LineHeight/width) -- (TextWidth,0); \stopreusableMPgraphic \definelayer[decorations][position=yes,option=test] \setupbackgrounds[page][background=decorations] \starttext {\ss\bfc A chapter title} \blank[small] {\ss\bfx \date \hfill Author Name} \setlayer[decorations][location=r]{\reuseMPgraphic{rightwave}} \input knuth \page {\ss\bfc A very long chapter title on two or more lines} \blank[small] {\ss\bfx \date \hfill Author Name} \setlayer[decorations][location=r,dx=-\cutspace]{\reuseMPgraphic{leftwave}} \input knuth \stoptext Just one problem is left. The graphic occupies space in the text layer as if the location was set to rb. If you place it with the position=no option, it is properly placed in the background and it doesn't disturb the text. Is this a bug or a feature? I tried to play a bit with the bounding boxes, but I think I don't understand them that well.

Footnotes: Individual number styles
by C. 06 Apr '11

06 Apr '11

Sorry to bother again, but how do I change the style of the footnote number that is IN THE TEXT. Not the ones under the line, I can manipulate those with numbercommand. Let's just say I want a normal serif body text, but the footnote numbers are sans serif (or red, if you will) To clarify: This is the main² text. The little two after main wants to be painted red. Here comes more text... __________ ² This two down here does not want to be red. Is this possible?

(Ctx)Lua, diacritics & string.upper()
by Procházka Lukáš Ing. - Pontex s. r. o. 06 Apr '11

06 Apr '11

Hello, is there a possibility to use Ctx Lua to convert strings containing diacritics to upper/lower case? I have a .cld file, UTF-8, and ("Přehledná"):upper() gives "PřEHLEDNá" whilst the desired result is "PŘEHLEDNÁ". Is there a way how to solve this? (Maybe another function than Lua's "string.upper()".) Kind regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

Footnotes set in columns have no line break
by C. 05 Apr '11

05 Apr '11

Hello, I want my footnotes in columns, but there is apparently no line breaking going on (text from the first column is overlapping the second and so on). Example: \setupfootnotes[n=2] \starttext \dorecurse{6}{\input hawking\footnote{Nevertheless, if the exponential growth continued, there would be ten.}} \stoptext This DOES give the desired output in the online context thingy (i.e MkII), but not my win32 minimals installation with MkIV.
