Re: [NTG-context] Again: LuaTeX error: invalid escape sequence near '\i'

The following two commands seem to do the same: \defineexpandable\... \def\... And this two also do the same: \define\... \unexpanded\def\... \def is a low-level-command and shouldn't be used. Right? Regards Janis

Again: LuaTeX error: invalid escape sequence near '\i'
by Jan Heinen 19 Apr '13

19 Apr '13

An example which was working with ConText (version beginning 2012) - and now I get an error: \define\imagepath {/home/janis/images} \starttext \externalfigure[\imagepath/test.jpg] \stoptext LuaTeX error [string "\directlua "]:1: invalid escape sequence near '\i' Without my parameter \imagepath there ist no problem. And if I want to see the "echo" of the parameter with \imagepath I get "/home/janis/images" which I expect. I need parameters very often. How can I use my parameter \imagepath in \externafigure? Regards Janis

Is fine-grained grid control possible?
by Tom Ellis 19 Apr '13

19 Apr '13

I asked a question on tex.stackoverflow, and it was suggested ConTeXt could help and that I should repost my question here. http://tex.stackexchange.com/questions/108850/is-fine-grained-grid-control-… I want to make a variety of checklists which are essentially based on a grid layout. I care about having fine-grained control over the exact placement of labels and boxes. I do not care about paragraphs, hypenation, equations, or anything like that which I know TeX is very good at. Is ConTeX a good fit for my needs? How could I do it? I've already though about Tikz and PGF but I don't think they give me enough fine-grained control. If I fail to find a way to solve my problem using TeX I will probably explore SVG and PostScript. Here are some examples of the kind of thing I would like to do that I pulled from an image search for "checklist" * https://studenttechportfolio.wikispaces.com/file/view/checklist.png/3434346… * http://checklisttemplate911.com/wp-content/uploads/2012/02/checklist-templa… * http://img.docstoccdn.com/thumb/orig/72289360.png * http://www.bimmerfest.com/forums/attachment.php?attachmentid=88940&stc=1 * http://theorganisedhousewife.com.au/shop/wp-content/uploads/2012/12/confere… * http://2.bp.blogspot.com/-piQobSY-8Mw/Tcihq580IgI/AAAAAAAAAgE/Fd0AQD1e69Y/s… * http://www.dbh.govt.nz/UserFiles/Image/Publications/building/weathertightne… * http://spxcooling.com/images/M92-1447C-s.jpg Thanks, Tom

Missing number error, related to setupcolumnsetlines
by Lars Huttar 19 Apr '13

19 Apr '13

Hello, I've got a "Missing number error, treated as zero". I've whittled the problem code down to this minimal example: \definecolumnset [abbcolumn] [n=2,distance=5mm,balancing=yes] \setupcolumnsetlines[abbcolumn][1][1][60] \setupcolumnsetlines[abbcolumn][1][2][60] \starttext \startcolumnset[abbcolumn] foo \stopcolumnset \stoptext By contrast, if I remove the \setupcolumnsetlines commands, the error goes away. (But I think I need those commands, in case the text has more than 60 lines.) Also, if I run the example shown on this page http://wiki.contextgarden.net/Command/setupcolumnsetlines which seems very similar to mine, it works fine; no errors. Based on the latter working example, I tried adding the following to my minimal example that fails: \switchtobodyfont[small] or \setupcolumnsetstart[abbcolumn][1][1][1] \setupcolumnsetstart[abbcolumn][1][2][1] but neither one solved the problem. Here is more of the error output I received when running TeX on the minimal example shown at the start of this email: ! Missing number, treated as zero. system > tex > error on line 8 in file minimalex-133.tex: Missing number, treated as zero ... 1 \definecolumnset [abbcolumn] [n=2,distance=5mm,balancing=yes] 2 3 \setupcolumnsetlines[abbcolumn][1][1][60] 4 \setupcolumnsetlines[abbcolumn][1][2][60] 5 6 \starttext 7 \startcolumnset[abbcolumn] 8 >> foo 9 \stopcolumnset 10 \stoptext 11 <to be read again> \otr:1:43 \OTRSETdoifcellelse ...er #1:\number #2\endcsname \@EA \secondoftwoarguments... \@@ar@@1 ...ellelse {\mofcolumns }\columnlastcell {\global \advance \columnl... \redoloop ->\expandrecursecontent \endofloop <to be read again> { <inserted text> 44 ... l.8 f oo ?

Lucida doesn't work in TL 2013 / latest ConTeXt
by Mojca Miklavec 19 Apr '13

19 Apr '13

Hi, in TL 2013 neither \setupbodyfont[lucida] nor \setupbodyfont[lucidanova] works. The first one gives: !LuaTeX error: Invalid local font in font lbr! ==> Fatal error occurred, no output PDF file produced! and the other one complains about ! Math error: parameter \Umathquad\displaystyle is not set. (I've set "export TEXMFLOCAL=/path/to/texmf/with/both/lucidas".) When trying the same with latest distribution I get ! LuaTeX error .../context/tex/texmf-context/tex/context/base/math-act.lua:101: attempt to perform arithmetic on field 'size' (a nil value) stack traceback: .../context/tex/texmf-context/tex/context/base/math-act.lua:101: in function 'mathematics_checkprivateparameters' [string "local mathematics_initializeparameters = math..."]:10: in function 'runner' .../context/tex/texmf-context/tex/context/base/math-act.lua:39: in function 'assignmathparameters' .../context/tex/texmf-context/tex/context/base/math-vfu.lua:917: in function <.../context/tex/texmf-context/tex/context/base/math-vfu.lua:537> (...tail calls...) .../context/tex/texmf-context/tex/context/base/font-def.lua:423: in function 'read' .../context/tex/texmf-context/tex/context/base/font-ctx.lua:947: in function 'definefont_two' [string "\directlua "]:1: in main chunk. system > tex > error on line 52 in file /Users/mojca/context/gnuplot/mojca/texmf/doc/context/third/gnuplot/gnuplot-context-doc.tex: LuaTeX error ... and with lucidanova I get the same error as in TeX Live. I'm using \sometxt{} inside metapost code to draw labels, so maybe that's connected. Mojca

Still having trouble with that pesky ISBN field in my bibliography. The file makes it to the book.bbl file but never prints no matter what .bst file I reference. Here is an extract from the generated book.bbl file: \startpublication[k=Bah2011,t=book, a={{Bah}},y=2011, n=4,s=Bah11] \author[]{Tavmjong}[T.]{}{Bah} \pubyear{2011} \title{Inkscape: Guide to a Vector Drawing Program} \isbn{978-0-13-27641-8} \city{Upper Saddle River, NJ} \pubname{Prentice-Hall} \stoppublication Any suggestions?

Thank you very much. I hope that the module in https://github.com/mojca/context-gnuplot/ is hotfixed now, thanks to Marco's extensive support. If anyone is willing to do a couple more basic tests, I would be grateful. I plan to upload this version to CTAN to get it into TeX Live and our distribution. Apart from that, Marco is working on a heavily modified version of the module (for MKVI). Once that one is tested, we'll upload it as well, but this patch is just to make the module usable again. I'm very sorry that it took me so long. Mojca

\bTD\numexpr\currentTABLErow\minusone\relax\eTD
by Alan BRASLAU 19 Apr '13

19 Apr '13

Hello, I naively tried using \bTD\numexpr\currentTABLErow\minusone\relax\dTD in a TABLE. As I do not master even simple calculations under TeX, I do not see what I am missing in order to label TABLE rows, starting from 0? (Row 1 is a heading, set off by \bTABLEhead\eTABLEhead, which is why I am looking to subtract 1 from \currentTABLErow, but this does not matter of course. But perhaps the addressing of TABLE rows, including within \setupTABLE, should or could handle this situation? This is a secondary question to think about...) Alan

gnuplot module broken

Hi Mojca et al. todays beta broke the gnuplot module. This is probably due to the changes in the MP inclusion mechanism. \usemodule [gnuplot] \starttext \stoptext Marco
