endlinechar redefinition
by Vit Zyka 07 Jun '07

07 Jun '07

Hi Hans, Jaroslav Hajtnar (in czech TeX list) encountered the problem with \input primitive redefinition. He uses a macro package for comma separated value file (CSV) inclusion. It redefines some catcodes and \endlinechar before start reading such file by \input. The problem is that during reading CSV the reading is interrupted by reading another file like \readfilename ->pdfr-ec (c:/TeXLive2005/texmf-context-a/tex/context/base/pdfr-ec.tex ConTeXt macro \input takes care about catcodes but not about \endlinechar so in this situation the file pdfr-ec is read with wrong \endlinechar which causes error. We believe that system solution is the ConTeXt takes care about \endlinechar when automatically starts reading some standard files. Please Hans can you look at it? Thanks Vit ------------------ Minimal demo attached. As a result of this problem, see the '00000' in the lower left page corner. Actually it is character ^^X (0x18, part of per-cent/per-mil char) which is used as \endlinechar delimiter.

How to make \framed ignore the width of the rule
by Aditya Mahajan 07 Jun '07

07 Jun '07

Hi, How can I make \framed ignore the width of the rule? I am trying to typeset internet protocol headers, but I cannot fully get what I want. Here is my attempt: \unprotect \makecounter{v!protocolheaderlength} \defineframed[protocolfieldheader] [location=lohi,height=3\lineheight,offset=none,strut=yes] \def\startprotocolheader {\dodoubleempty\dostartprotocolheader} \def\dostartprotocolheader[#1][#2]% {\getparameters[c!protocol][#1]% \let\field\protocolheaderfield \resetcounter{v!protocolheaderlength}% \vbox\bgroup % \ruledvbox\bgroup \removeunwantedspaces \dontleavehmode \protocolfieldheader[frame=on,width=\c!protocolbits\c!protocolunitsize]% {\let\\\crlf\bold #2}\crlf} \def\stopprotocoloheader {\egroup} \def\protocolheaderfield#1#2% {\doif{\countervalue{v!protocolheaderlength}}{\c!protocolbits} {\resetcounter{v!protocolheaderlength}\crlf}% \removeunwantedspaces \dontleavehmode \protocolfieldheader[width=#1\c!protocolunitsize]{\let\\\crlf #2\\(#1)}% \incrementcounter{v!protocolheaderlength}{#1}} \protect % \showstruts % \showboxes \starttext % Why should unitsize=1mm. Are things being scaled by another factor? \startprotocolheader[bits=16,unitsize=1mm][General MAC Headers] \field {1} {HT} \field {1} {EC} \field {6} {Type} \field {1} {ESF} \field {1} {CI} \field {2} {EKS} \field {1} {Rsv} \field {3} {LEN MSB} \field {8} {LEN LSB} \field {8} {CID MSB} \field {8} {CID LSB} \field {8} {HCS} \stopprotocoloheader \stoptext Notice that all the lines are not of the same size. It seems that the rules of framed are causing the frame to be of a larger width. Also am I missing a scaling factor in width= expressions above. Everything looks fine with unitsize=1mm, but the final figure is clearly larger than 16mm. I am confused as to what is happening. Is there any better way to do this? Thanks, Aditya

Beautiful source code
by David Arnold 07 Jun '07

07 Jun '07

Hans, I'm revisiting the metafun manual and I am marveling at the format of the source code. For example: \starttabulate[|lT|l|] \HL \NC \METAPOST\ code \NC mathematical equivalent \NC \NR \HL \NC (x,y) shifted (a,b) \NC $(x+a,y+b)$ \NC \NR \NC (x,y) scaled s \NC $(sx,sy)$ \NC \NR \NC (x,y) xscaled s \NC $(sx,y)$ \NC \NR \NC (x,y) yscaled s \NC $(x,sy)$ \NC \NR \NC (x,y) zscaled (u,v) \NC $(xu-yv,xv+yu)$ \NC \NR \NC (x,y) slanted s \NC $(x+sy,y)$ \NC \NR \NC (x,y) rotated r \NC $(x\cos(r)-y\sin(r),x\sin(r)+y\cos(r))$ \NC \NR \HL \stoptabulate Pasting into my email program does not do this code snippet justice, as in the Metafun source, all of the \NC's are aligned vertically, as are the \NR's. How do you do this? Does your editor align these for you, or do you painstakenly align them manually with the spacebar?

non-interactive underlining
by Alan Bowen 06 Jun '07

06 Jun '07

How do I turn off interaction when using \startunderline... \stopunderline. Currently the underlining shows in blue, but I need it in the same color as the typeface (black). Is there something equivalent to \setupunderlining[interaction=off]? Thanks for any tips or clues. Alan

questions about math formula
by fdu.xiaojf＠gmail.com 06 Jun '07

06 Jun '07

Hi all, I have two questions about math formula. 1) I'd like to use \startalign to typeset mathematical formulas since it is more convenient than \eqalign. But the formula number cannot be located between two lines just as \eqalign can. I hope following example can make me clear. \starttext \placeformula \startformula \eqalign{ a + b & = c + d\cr & = e + f\cr} \stopformula \placeformula \startformula \startalign \NC a + b \NC = c + d \NR[+] \NC \NC = e + f \NR \stopalign \stopformula \stoptext The number of equations in second formula can only be put on the first line or second line but not between them. My question is how to make the location of formula number in \startalign the same as it is in \eqalign ? 2) It seems that \left and \right cannot be used on separate groups. Here is a simple example: \starttext \placeformula \startformula \eqalign{ a & = \left(\frac{b+c}{d+e}\cr &\phantom{=~} + \frac{g}{h}\cr} \stopformula \stoptext If I change \left and \right to \big, it compiles successfully. But I think \left and \right are more convenient. Are there some solutions to use \left and \right in this situation ? Regards, Xiao Jianfeng
