indenting in XML environment
by Christopher G D Tipper 16 Jan '06

16 Jan '06

Ok, after taking deep breath I'll try this issue again. I got indenting to work after putting \noindenting inside its own environment. However, the following code block stopped working recently and I don't know why: \defineXMLenvironment[body] {\bgroup \rm\setupwhitespace[none] \setupindenting[small,yes] \startcolumns[rule=on,n=2,tolerance=strict] {\noindenting} } {\stopcolumns \egroup} It just doesn't indent anything, even after removing the {\noindenting} environment.

columns issues
by Henning Hraban Ramm 16 Jan '06

16 Jan '06

Hello wizards! The \startcolumns ... \column ... \stopcolumns block handling seems somewhat broken. Maybe these "old" columns are deprecated, but I guess they should work. (And I would like to document them.) Consider this: \starttext \input ward \startcolumns \input ward \column \input knuth \stopcolumns \input tufte \stoptext In this case \column works (it doesn't seem to work always), so that the left column is much shorter than the right one. But the following paragraph (tufte) is typeset just after the last line of the left column, so that some lines overprint. And with [rule=on] the rule is only as short as the left column. [option=background] also only considers the leftmost (or first in [direction=left]) column. Maybe this behaviour is sometimes useful, but I don't think it should be default. [balance=no] doesn't affect the balancing of columns, but flushes the page (i.e. the tufte paragraph moves to the next page). With [n=3] you see that it doesn't use the whole remaining page. The whole problem seems to be \column, because without that, everthing (?) works. I didn't find out what the options ntop, blank, height and align are for; I tried several values and nothing seemed to change. [The source is http://source.contextgarden.net/page-mul.tex but I don't understand too much of it.] After looking in the manual, I guess I should consider using paragraphs or columns sets for most of my use cases, but anyway...

Notes for Scite
by David Arnold 16 Jan '06

16 Jan '06

All, I already have a few colleagues who have set up perl, ghostscript, gsview, miktex, context, and windedt on their XP machines. Does someone have instructions for setting up Scite and configuring it for Context on top of these existing installations?

Figure libraries
by David Arnold 16 Jan '06

16 Jan '06

All, After you run: figures $ texexec --pdf --use=fig-make --mode=letter figlibSection3.xml are the figures embedded in figlibSection3.pdf? That is, could you now remove the files used to create figlibSection3.pdf?

Alignments side by side
by David Arnold 16 Jan '06

16 Jan '06

All, I am wondering how I can put two alignment environments side-by-side? For test purposes, it's OK to use this twice. \placeformula[-] \startformula \eqalign{ f(x)&=x^2-2x-3\cr f(x)&=x^02x+1-1-3\cr f(x)&=(x-1)^2-4} \stopformula I'd like to get two of these side-by-side, or something that will typeset a similar result side-by-side. Thanks.

layer question
by Henning Hraban Ramm 15 Jan '06

15 Jan '06

Consider this example: \definelayer[extras] [width=\paperwidth, height=\paperheight] \setlayer [extras] [x=2cm, y=5cm] {something} \setupbackgrounds[page][background=extras] This is ok, the placement is relative to the upper left edge of the paper. But following the Details manual, I should be able to use \placelayer[extras] instead of the background stuff. But then the placement is relative to the upper left edge of the text area. Is this intended? Grüßlis vom Hraban! --- http://www.fiee.net/texnique/ http://contextgarden.net http://www.cacert.org (I'm an assurer)

postponed processing
by Henning Hraban Ramm 15 Jan '06

15 Jan '06

Me again... I'd like to define an address layer in my environment: --- start env -- \definelayer[senderlayer] [x=0mm, y=0mm, width=\paperwidth, height=\paperheight] \def\Sender#1#2#3{\setvalue{SenderKey#1}{#2}\setvalue{SenderVal#1}{#3}} \def\GetSenderLine#1{\bTR\bTD\doiftextelse{\getvalue{SenderKey#1}}% {\getvalue{SenderKey#1}:}{}\eTD\bTD\getvalue{SenderVal#1}\eTD\eTR} \setlayerframed[senderlayer] [%corner={right}, location={left,bottom}, x=\dimexpr(\getvalue{LogoHOffset}-\bleed), %\getvalue{LogoHOffset}, y=\getvalue{LogoHeight}] % \dimexpr(\getvalue{LogoHeight}+\topspace) [height=46mm, width=\dimexpr(\getvalue{SenderKeyWidth}+\getvalue {SenderValueWidth}), frame=off, offset=none, align={left,top}]{% \setupTABLE[frame=off] \setupTABLE[x][1][width=\getvalue{SenderKeyWidth}, align=left, style= {\keystyle\strut}] \setupTABLE[x][2][width=\getvalue{SenderValueWidth}, align=right, style={\valstyle\strut}] \bTABLE \dostepwiserecurse{1}{9}{1}{% count from 1 to 9, step 1 \expanded{\GetSenderLine{\recurselevel}} } \eTABLE } \def\EnableSender{\setupbackgrounds[rightpage][page] [background={\currentvalue, senderlayer}]} --- stop env --- and use that later in a product/component: --- start text --- \Sender{1}{Name}{Hraban} \Sender{2}{Web}{www.fiee.net} \EnableSender --- stop text --- Of course it doesn't work, because the Sender values aren't set via typesetting the address in the environment, and \currentvalue in \EnableSender hasn't the right value either. Holger solves this in his letter style (wiki) via setups. Is that the best approach? How else could I postpone the senderlayer processing? (I guess it would work with some expansion magic, but I'd like to stay at ConTeXt's surface as much as possible.)

multiple backgrounds
by Henning Hraban Ramm 15 Jan '06

15 Jan '06

I'm playing around with layers and try to rewrite the letter style in a cleaner way. How can I use several layers as page backgrounds and switch them on and off independently from each other? With \setupbackgrounds[rightpage][page][state=start, background=logolayer] \setupbackgrounds[rightpage][page][state=start, background=senderlayer] the second background overwrites the first, but I can't define them together, because there could be several combinations of 5-7 layers.

spurious space in cite
by Hans van der Meer 15 Jan '06

15 Jan '06

I was typesetting bibliography references with the command \cite[data][ref] and then found that a spce preceded the author name; surrounding the space with X and Y, it gives "X Yauthor" instead of "XYauthor I was able to trace it down to the macro invertedshortauthor in thise case, but I suspect the others (invertedauthor, normalauthor, normalshortauthor) will exhibit the same phenomenon. The macro is: \def\invertedshortauthor#1#2#3#4#5% {\bibdoif{#2}{#2\bibalternative\c!vonsep}% #3\bibalternative\c!surnamesep \bibdoif{#5}{#5\bibalternative\c!juniorsep}% \bibdoif{#4}{#4\unskip}} tracingmacros shows an empty #2-argument takes the \c!vonsep, in bibl- apa.tex defined as a space. I first wondered if the \bibdoif's shouldn't be replaced by a \bibdoifnot. Anyway, that makes the spurious spaces go away. But it seems not right, so I investigated the bibdoif's and found the following behaviour when calling with empty and nonempty arguments. bibdoif:\crlf empty = \bibdoif{}{empty}\crlf notempty = \bibdoif{x}{notempty}\par bibdoifnot:\crlf empty = \bibdoifnot{}{empty}\crlf notempty = \bibdoifnot{x}{notempty}\par bibdoifelse:\crlf empty = \bibdoifelse{}{first}{second}\crlf notempty = \bibdoifelse{x}{first}{second}\par Typesetting gives as a result: bibdoif: empty = empty notempty = notempty bibdoifnot: empty = notempty = bibdoifelse: empty = first notempty = first So I have my doubts about the doif's. Finally another observation on the typesetting by \cite[data][ref]. When typesetting a reference ending on a period, for example "Publ. Co. Inc.", the result has a double period "Publ. Co. Inc.." That looks somewhat silly. yours sincerely, dr. H. van der Meer

MPinclusions
by Hans van der Meer 15 Jan '06

15 Jan '06

I thought to incrementally add to MPinclusions by successive blocks \startMPinclusions ...... \stopMPinclusions \startMPinclusions ...... \stopMPinclusions etc. But according to the generated mp-file it seems to incorporate the last one only. Is this correct and if so, is it an option to allow appending in the above manner? Or will that be too difficult to build. yours sincerely, dr. H. van der Meer
