\startvariables failed after the current update
by Zhichu Chen 28 Oct '08

28 Oct '08

Hi there, I haven't updated my ConTeXt distribution for a very long time (for the internet connection problem here) and somehow my network worked, so I use ctxtools --update to make an update. During the updating, I got some error message like "I can't find mult-def.tex" and some other files more. Weird, because I do have those files and kpsewhich can locate them. I just input the needed files WITH the path and seemed OK. To make sure, I made another ctxtools --update and this time no error messages. Anyway, I compiled a used-to-be-working file and failed because some "Undefined control sequence" and I found the "undefined" macros are the \c!xxx and \v!yyy macros which I defined them in \startvariables all yyy: yyy \stopvariables \startconstants all xxx: xxx \stopconstants any explanations? -- Best Regards Chen ---------------------------------------------------------------- Zhi-chu Chen | Shanghai Synchrotron Radiation Facility No. 2019 | Jialuo Rd. | Jiading | Shanghai | P.R.

tikz and metapost
by Alan BRASLAU 28 Oct '08

28 Oct '08

Following some exchange off-list (trying to figure out how tikz under context got broken), the subject of understanding pgf/tikz with respect to metapost came up. I am posting a follow-up here as it may be of interest to others on the mailing list, those who know metapost very well as well as those, like myself, who are still learning how to use different graphics tools.

I myself find gnuplot to be fatally flawed and have never liked using it. (I still sometimes produce graphics using an old program written in K&R C that generates HPGL for pen plotters, with a filter that then creates postscript. Now THAT is almost stone age! But this program can also handle an arbitrary number of points VERY efficiently, only limited by the size of your storage device.) > If you need some complex curve, TikZ is improving in > that area, but in metapost it's out-of-the-box to draw it. Why did Till Tantau write pgf/tikz? Clearly he knew metapost, so another route could have been to develop a standard library of metapost macros. I'm asking these questions here as there seems to be a preference (or prejudice) towards metapost amongst the context community. Indeed, it appears pretty powerful. But as Mojca wrote about glimpsing at the pgf/tikz manual, it too is very rich and I have yet to learn about all of the new features that were introduced in pgf-2.0. Thus, I am trying to figure out where to invest my learning efforts. Do any other metapost and/or pgf-tikz experts have something to contribute to this query? -- Alan Braslau

Load context format at runtime (from luatex)
by Mildred Ki'Lya 28 Oct '08

28 Oct '08

Hi, I would like to run (if possible) the context format at runtime. In fact, I'd like to create a custom format for my own document and I want my format to inherit ConTeXt (mostly because of utf-8 support). At the beginning of my document, I added: \input format And at the beginning of format.tex, I added: \input context But now, when I execute the document using (pdf)luatex, I get an error in some lua chunk: pdfluatex document.tex This is LuaTeX, Version snapshot-0.25.4-2008091110 (Web2C 7.5.7) (document.tex (format.tex (/usr/share/texmf-dist/tex/context/base/context.tex (/usr/share/texmf-dist/tex/context/base/syst-pln.tex) (/usr/share/texmf-dist/tex/context/base/syst-prm.tex) (/usr/share/texmf-dist/tex/context/base/luat-env.tex ! LuaTeX error [string "luas[0]"]:1: attempt to call field 'luafilechunk' (a ni l value). \ctxluabyteload ...nvironment.luafilechunk("#1") } \ ...fproductionrun \else \ctxluabyteload {#1}{#2} \fi \global \everyloadluac... l.168 \registerctxluafile{luat-env}{1.001} ? If I use context instead of (pdf)luatex, it seems there is an infinite loop when context.tex is loaded from my format in the file /usr/share/texmf-dist/tex/context/base/syst-prm.tex If I remove the inclusion of context in my format (the \input line) I get another error (but I can't find where it is). The last lines looks like: context document.tex MtxRun | loading configuration for /usr/share/texmf/web2c from /home/mildred/luatex-cache/context/6300afb4995fe38c77e9b86ed1ef1028/trees/f7d1b3c25487ab1e1035aff1c53b90da (./document.tex ConTeXt ver: 2008.05.21 15:21 MKIV fmt: 2008.10.27 int: english/english language : language en is active report >> utilityfile: not present system : cont-new loaded (/usr/share/texmf-dist/tex/context/base/cont-new.tex systems : beware: some patches loaded from cont-new.tex (/usr/share/texmf-dist/tex/context/base/cont-new.mkiv lua : used config path - /usr/share/texmf/web2c/texmf.cnf lua : used cache path - /home/mildred/luatex-cache/context/6300afb4995fe38c77e9b86ed1ef1028 ) (/usr/share/texmf-dist/tex/context/base/cont-mtx.tex)) system : cont-old loaded (/usr/share/texmf-dist/tex/context/base/cont-old.tex loading : Context Old Macros ) system : cont-fil loaded (/usr/share/texmf-dist/tex/context/base/cont-fil.tex loading : Context File Synonyms ) system : cont-sys.rme loaded (/usr/share/texmf-dist/tex/context/user/cont-sys.rme (/usr/share/texmf-dist/tex/context/base/type-tmf.tex) (/usr/share/texmf-dist/tex/context/base/type-siz.tex) (/usr/share/texmf-dist/tex/context/base/type-otf.tex)) bodyfont : 12pt rm is loaded specials : tex loaded system : document.top loaded (./document.top specials : loading definition file tpd (/usr/share/texmf-dist/tex/context/base/spec-tpd.tex specials : loading definition file fdf (/usr/share/texmf-dist/tex/context/base/spec-fdf.tex (/usr/share/texmf-dist/tex/context/base/spec-fdf.mkiv)) specials : fdf loaded ) specials : fdf loaded ) (./format.tex) !

And I also would prefer using the generic (pdf)luatex instead of context. Thanks.

--arrange vs. --pdfarrange

This might be a stupid question, but: what's the difference between the --arrange and --pdfarrange options for texexec? Greets, -- Marcin Borkowski (http://mbork.pl) - Why are vim users so terribly egocentric? - Because they begin every sentence with `I'.

27 Oct '08

Hi all, referencing a subitem I get also the item (1.a, 2.c and so on). Can I split them or get only the subitem? \starttext \startitemize [n] \item [number] one \startitemize [a] \item [letter] letter \stopitemize \stopitemize Look at number \in[number] letter \in[letter] \stoptext Normal output: Look at number 1 letter 1.a Wanted result Look at number 1 letter a Many thanks -- Diego Depaoli

I noticed that the modules.contextgarden.net/bib page says you're editing the apa style. Here are two corrections I made. Perhaps they will help. 1. line 286: changed \insertpublisher{. }{.}{.} to \insertpublisher { }{.}{.} Why: prevents double periods after the title. It's what you did for several other publication types in the version you sent me on August 10. 2. line 384: commented out insertpublisher line Why: this is the entry for unpublished documents so I wasn't sure why it was there. More importantly, if it is left uncommented, there are two periods after the title. Thanks! mjg

A problem with itemizations
by Marcin Borkowski 27 Oct '08

27 Oct '08

Hi, I have a problem with \startitemize ... \stopitemize. Sometimes (I have no idea when, but this effect is fully repeatable!) I get a page break just before a \startitemize. It is nested (second level) and follows one line of another item at the 1st level. It seems that adding [intro] won't help. The problem occurs with [columns,two]; I don't know whether this has any influence - when I change the setup (in the preamble) the page breaks fall in different places, and all my 2nd level itemizations are 2nd level (and I have quite a lot of them). Any ideas? I know that the above is rather vague, but it's difficult to prepare a minimal example etc. Also, Hans, do I get it correctly that the itemization code will get rewritten in MkIV? If yes, is there any chance of having unpacked itemizations in 2 and more columns? And any chance of having an explicit column break (or a preference) in multicolumn itemizations?

Page arranging: 2SIDE, 2UP, 2DOWN, 2*2, 2**2
by Marcin Borkowski 26 Oct '08

26 Oct '08

What is the difference between the above? In particular, do I get this correctly: (*) 2SIDE just puts 2 pages onto one sheet, in the following order: 1 2 3 4 ... (*) 2UP prepares a booklet I'm not sure if I understand the rest. I tried 2DOWN, but got only even pages (?). And with 2*2 and 2**2 got the same (?) arrangement, but I'm not sure what it's for. Thanks & greets! -- Marcin Borkowski (http://mbork.pl) People can be divided into 10 groups: those who like the binary system and those who don't.
