Itemize not breaking across pages?
by Alasdair McAndrew 11 Mar '11

11 Mar '11

I am setting up notes and exercises for my students. Each set of exercises is in an itemize environment, and each \item consists of a table of problems. The trouble is, the itemize doesn't break across pages - I have to put manual page breaks in. How can I encourage automatic page-breaks? Thanks, Alasdair

ConTeXt in MiKTeX
by Carlos Breton Besnier 11 Mar '11

11 Mar '11

Hello. I need ConTeXt Mark IV environment on a USB stick because I don´t have administrative rights over the computer. The operating system is windows. I downloaded MiKTex 2.9 portable (Texworks) and ConTeXt package but I can not get it run. I've searched on the web how configurate Texworks but I did not find a manual. Could you help me? Thanks.

\synctex=1 ignored in mkiv
by Mojca Miklavec 11 Mar '11

11 Mar '11

Dear Hans, subject says it all: when I use \synctex=1 in mkiv, I don't get any .synctex.gz file. The --synctex switch works however (which is exactly the opposite of what used to be the case a while ago :). In MKII both works. Mojca

Re: [NTG-context] Am not getting Roman numeral page numbers in MKIV
by Jeong Dalyoung 11 Mar '11

Dear Tom, Please add following lines in the preamble, then you will get roman numerals. \definestructureconversionset[frontpart:pagenumber][][romannumerals] \definestructureconversionset[bodypart:pagenumber] [][numbers] Also I use \startstructureblockenvironment[backpart] instead of \startsectionblockenvironment[backmatter]. cheers, and enjoy ConTeXt!

Verbatim text: intext & colors (mkiv)
by Reviczky, Adam 11 Mar '11

11 Mar '11

Hi, When using verbatim text (for source code) in mkiv: "Line numbers in the text" as well as /BTEX … /ETEX (for colors) don't work. It is fine using mkii. Attached the two minimal examples. Adam

fonts.enc.reencodings works with latex but not with context
by Ulrike Fischer 11 Mar '11

11 Mar '11

I have now reencoded my first chess font. I'm now trying to find out how to setup things so that context users could also benefit from the reencoding. But the equivalent code of the code working with latex doesn't work in context \startluacode fonts.enc.reencodings["cfss-lsf-std"] = { --%bishop [66] = 8226, --%king [75] = 162, --% Knight [78] = 167, --%Queen [81] = 163, --%Rook [82] = 182, --%Pawn [112]= 223, } \stopluacode \font\alfonsouc="name:ChessAlfonso-X:mode=base:reencode=cfss-lsf-std" \starttext \alfonsouc \char75\char81\char82\char66\char78\char112 \stoptext I get the error "! LuaTeX error <main ctx instance>:15: attempt to index field 'reencodings' (a nil value)" It only works if I copy the code from font-dum.lua to the document. Isn't the code already loaded? Btw: There is a small typo in luat-dum.lua. Line 77 is missing an "s" found = kpse.find_file(name,"other text files") ^^^ missing. -- Ulrike Fischer

Making all bold faced text colored?
by Alasdair McAndrew 11 Mar '11

11 Mar '11

In some overheads, I'd like all bold-faced font to appear in a given color, say red. How do I set this up, so that {\bf some text} will display "some text" in red? Thanks, Alasdair

writing physical quantities in maths mode
by Ian Lawrence 11 Mar '11

11 Mar '11

Morning all, I have a need to write a lot of physical quantities - these should be in text mode. Mostly I can manage, but subscripts are causing me grief Eg \startformula \startmathalignment[n=3] \NC \text{F}\NC =\NC {\text{GMm} \over \text r^2}\NR \NC \text {force}_G \NC =\NC {\text{G} \times \text m_1 \times \text m_2 \over \text r^2}\NR \NC \text {force \low G} \NC =\NC {\text{G} \times \text m_1 \times \text m_2 \over \text r^2}\NR \stopmathalignment \stopformula In the second and third equantions I'd like force subscript G all in roman, not italic, to follow the standard conventin. The first one puts the G in the correct place, but in italic The second one manages roman, but it's offset. I suspect I could kludge this with hskips, but I think there should be a more elegant solution. If there is a paper on writing physics in ConTEXt (not maths... I have found the helpful couple by Aditya Mahajan) that would save me time. For most relationships I am planning to use predefine quantities, then slot these in Like this in the header \define \forceQA {{\sl F}/\Newton} \define \forceQU {{\tf force}/{\tf newton}} \define \forceQ {{\tf force}} (etc) And this in the body \startformula {\forceQA \over \massQA} = \accelerationQA \stopformula \startformula {\forceQU \over \massQU} = \accelerationQU \stopformula \startformula {\forceQ \over \massQ} = \accelerationQ \stopformula Any more elegant solutions out there? Thanks Ian

Roman numeral page numbers produced in MKII
by Tom 10 Mar '11

10 Mar '11

After posting the message about the following code not generating lower-case Roman numeral page numbers, I tested the code with MKII and it works fine. There must be a difference in how page number conversion is done between MKII and MKIV. \definehead [intro][chapter] \setuphead [intro][number=no] \setuppagenumbering [state=start, conversion=romannumerals, location=bottom] \startsectionblockenvironment[frontpart] \definecombinedlist [content][intro,chapter,section] \stopsectionblockenvironment \startsectionblockenvironment[bodypart] \stopsectionblockenvironment \startsectionblockenvironment[backmatter] \stopsectionblockenvironment \starttext \setuppagenumber[state=start] \startfrontmatter %sample front matter \input knuth \completecontent[alternative=c,criterium=all] \chapter{Preface} \input knuth \stopfrontmatter \startbodymatter \setuppagenumber[state=start,conversion=number,number=1] \intro{Introduction} \input knuth \setupheadnumber[chapter][0] %resets first chapter number to 1 \setuppagenumbering [state=start, conversion=numbers, location=bottom] \chapter{I Was Born} \input knuth \chapter{I Observe} \input knuth \stopbodymatter \startbackmatter \stopbackmatter \stoptext Tom Benjey 717-258-9733 voice 717-243-0074 fax blog: www.TomBenjey.com

\copypages and friends
by Willi Egger 10 Mar '11

10 Mar '11

Hello Hans, I believe that there is a bug or something has changed from Context version 14 february and version 25 february. While in the older version the commands \insertpages and \copypages work as expected, the newest beta simply ignores the commands. There is no error message. Kind regards Willi
