Lua fonttester error
by Lutz Haseloff 26 Feb '10

26 Feb '10

Hi Hans Hi all, since yesterday evening (Context 2010.02.25 19:46 MKIV) the Lua fonttester doesn't work anymore. After starting it with mtxrun --script server --auto (MAPS 39, page E75 :-) I can see the Startpage in my Browser. After clicking fonttest the script breaks with following errormessage: MTXrun | requested action: mtx-server-ctx-fonttest.lua MTXrun | performing action: mtx-server-ctx-fonttest.lua MTXrun | locating script: C:/contextminimal/texmf-context/scripts/context/lua/mtx-server-ctx-fonttest.lua MTXrun | loading script: C:/contextminimal/texmf-context/scripts/context/lua/mtx-server-ctx-fonttest.lua MTXrun | return type: function ...textminimal/texmf-context/tex/context/base/l-aux.lua:212: attempt to index field 'patterns' (a nil value) C:\contextminimal> Greetings Lutz

How can I get a left space of, say 3cm? Wolfgang

TeX syntax -- a guide?
by James Fisher 25 Feb '10

25 Feb '10

Hi, After a few days working in "do what the tutorials say" mode, I now want to understand TeX from a programmer's mindset. I have not been able just by practise to work out what the syntactic rules of TeX are, and I am hoping that there is a sensible guide to this somewhere. However, searches for things like "tex syntax" draw a blank. Some of the things I want to understand, for example, are: (1) what is the distinction between square brackets and curly brackets after a command? (2) Why are there sometimes lists of square-bracketed lists after a command, each with lists of seeming arguments inside them? (2) What exactly are the "variables" in a TeX file? (I've seen variable-like things sometimes referred to just plainly, sometimes with preceding backslashes as if they were commands/macros). (4) Why can't I end a square-bracketed section with a final square-bracket on a line of its own, as I may do in other programming languages? (5) How are things like \subsection, \subsubsection, \subsubsubsection, ... implemented? I am used to languages in which there is only a finite set of commands; why is the logic here not more like \section[level=1], \section[level=2], ... ? (6) Perhaps I'm misunderstanding things and all this isn't actually the fundamental syntax of TeX but just adhoc syntax defined by various macros doing different things -- is this the case; to what degree can macros define syntax? Obviously I don't expect answers to all these here, but can someone point me to somewhere on the 'net that could answer them? The only other possibilities I can see are buying an expensive copy of the TeXbook, etc. Thanks all, James Fisher

Re: [NTG-context] Math in MKIV - HOWTO

Hi Mojca, After trying step 1 (vusialize the font) with Times math, I have the following error: systems : begin file math.tex at line 2 (c:/contextminimal/texmf-context/tex/context/base/font-run.mkii) color : system all is global activated ! Undefined control sequence. \doshowfont ...f \setstrut \dummy \localcolortrue \offinterlineskip \dostepw... <to be read again> \stoptext l.4 \stoptext The strange thing here is .mkii extension, while I definitely use mkiv. My script is \loadmapfile[original-youngryu-tx.map] \starttext \showfont[rtxptmr] \stoptext B.R., Vyatcheslav

MkII to MkIV
by Steffen Wolfrum 25 Feb '10

25 Feb '10

Hi, typesetting an old MkII written project with MkIV today gives more then 2000 "unable to resolve" warnings, like these ... !pages : flushing realpage 12, userpage 16 !backends : unable to resolve destination attribute 67 !backends : unable to resolve destination attribute 69 !backends : unable to resolve destination attribute 70 !backends : unable to resolve destination attribute 71 !backends : unable to resolve destination attribute 72 !backends : unable to resolve destination attribute 74 !pages : flushing realpage 13, userpage 17 !backends : unable to resolve destination attribute 75 !backends : unable to resolve destination attribute 76 !backends : unable to resolve destination attribute 83 !backends : unable to resolve destination attribute 80 !backends : unable to resolve destination attribute 81 !pages : flushing realpage 14, userpage 18 !backends : unable to resolve destination attribute 82 !backends : unable to resolve destination attribute 85 !backends : unable to resolve destination attribute 86 !backends : unable to resolve destination attribute 91 !backends : unable to resolve destination attribute 89 !backends : unable to resolve destination attribute 90 ... what does this mean? As that project did not even have 2000 \footnotes or \index or reference marks, what is meant? Paragraphs??? Steffen
