MKIV in TL2009
by Aditya Mahajan 23 Sep '09

23 Sep '09

Hi Hans and Taco, Perphas you guys already know this, but mkiv does not run in TL09. I tried generating the format and I get !!!!: Your luatex binary is way too old, you need at least version 0.42. The included luatex binary is (the date seems wrong?) Version beta-0.40.6-2009090923 (TeX Live 2009/Arch Linux) luatex.web >= v14240 Does this basically mean that in order to use mkiv with TL, I have to manually update the luatex binary? Aditya

How can I input Join?

Hi, I am doing my logic homework using ConTeXt. the command \Join (ref. http://w2.syronex.com/jmr/tex/texsym.old.html) seems to be missing in ConTeXt. (I searched showmathcharacters in context) How can I input that? Thanks Yue Wang

Hello Hans, Sorry for my insistence, but... mkiv lua stats : loaded fonts - 37 files: lmmono10-regular.otf lmmono12-regular.otf lmmono8-regular.otf lmmono9-regular.otf lmroman10-bold.otf lmroman10-regular.otf lmroman12-bold.otf lmroman12-regular.otf lmroman7-bold.otf lmroman7-regular.otf lmroman9-bold.otf lmroman9-regular.otf lmsans10-regular.otf lmsans12-regular.otf lmsans8-regular.otf lmsans9-regular.otf eufb10.tfm eufb7.tfm eufm10.tfm eufm7.tfm msam10.tfm msam7.tfm msbm10.tfm msbm7.tfm lmex10.tfm lmmi10.tfm lmmi12.tfm lmmi7.tfm lmmi9.tfm lmmib10.tfm lmmib7.tfm lmsy10.tfm lmsy7.tfm lmsy9.tfm minionpro-bold.otf minionpro-it.otf minionpro-regular.otf How can I get rid of all of these fonts except last three?

Mark IV

All, Hans recommended I contact the list with my inquiry. I'm running Leopard on a Mac, using Mactex, texlive 2008. I've updated my context with: sudo ctxtools --updatecontext On a first run of ctxtools, I get this error: loading : ConTeXt Core Macros / Environments ! Undefined control sequence. <argument> ...def \@EA \noexpand \csname \e!start \v!setups \endcsname {\beg... \expanded ...\long \xdef \@@expanded {\noexpand #1 }\@@expanded l.212 ...xpand\csname\e!stop\v!setups\endcsname}}} I hit "s" several time to scroll through the errors til it finishes, then run the command again: sudo ctxtools --updatecontext This time it seems to complete with no errors. This seem OK to folks? Now, I'd like to give MKIV a try. I see the following instructions: http://wiki.contextgarden.net/Running_Mark_IV Are they adequate for my platform? That is, will they work if I follow them to the letter? Or do folks have other advice? Thanks.

[OT] CMap Resources
by luigi scarso 22 Sep '09

22 Sep '09

http://opensource.adobe.com/wiki/display/cmap Welcome to CMap Resources! CMap (Character Map) resources are used to unidirectionally map character codes, such as a Unicode encoding form, to CIDs (Characters IDs, meaning glyphs) of a CIDFont resource. CMap resources, like CIDFont resources, include a /CIDSystemInfo dictionary that specifies /Registry and /Ordering strings that must match for compatibility between the two resources. In other words, a CMap resource can be used with a CIDFont resource only if their /Registry and /Ordering strings match. Although originally designed for use with CIDFont resources, CMap resources are also used for other purposes, such as by AFDKO's MakeOTF tool for building 'cmap' tables for OpenType fonts when the source font is a CIDFont resource. The CMap resources that are available are for the latest character collections, specifically Adobe-Identity-0, Adobe-GB1-5, Adobe-CNS1-5, Adobe-Japan1-6, and Adobe-Korea1-2. All of the CMap resources that are associated with each character collection are included. -- luigi

Hi, 1) > those fonts are loaded for math (and only once as fonts are shared) > Don't understand what 'shared' fonts mean, but how can I prevent these math fonts from loading? Maybe elaborate the typescript? 2) > this takes 2.5 seconds on my machine > > \starttext > \usetypescript[palatino] \setupbodyfont[palatino] test\par > \usetypescript[postscript] \setupbodyfont[postscript] test\par > \usetypescript[cambria] \setupbodyfont[cambria] test\par > \stoptext > Mine is 2.656sec, but actual time is > 5 sec (I had a lot of complaints about math issues like 'math virtual | unicode point U+1D6EB has no index 004B in vector tex-mi for font rtxmi' ) 3) Would it be reasonable to have ConTeXt as a service sitting in the memory and processing documents on demand? I believe that >2sec for processing a single page plain text document is ridiculous. Given modern computer power, I suppose it can be done instantly. (Or am I are mistaken?) Regards, Vyatcheslav

vardef with @# not working within context
by Matthijs Kooijman 22 Sep '09

22 Sep '09

Hi all, I've been fiddling around with metaobj a bit, but defining my own objects failed. After some debugging, I've reduced this to a metapost / context MkIV issue (so no metaobj specifics anymore). What happens, is that vardefs that use @# as a placeholder in their name only work when they are defined in an external .mp file. When I define them inside context (\startMPcode or \startMPinclusions), I get funny errors (mostly "Isolated expression", which seems to mean that the macro is not defined). I suspect this is because the way context extracts metapost code. Is this a fundamental problem, or could it be fixed? The following context file will easily reproduce the problem: \starttext \startMPcode vardef foo = draw (0mm,0mm)--(10mm,10mm); enddef; foo; vardef xy@# = (@#,@#) enddef ; draw xy0mm -- xy10mm; \stopMPcode \stoptext Running this file gives the following (first) error: mplib | mp terminal: >> xy0mm ! Improper `addto'. To illustrate that this is specific to the use of @#, I've included the foo vardef which does work properly. When I move the vardef xy.. line to a separate file, say foo.mp, and replace it with "input foo;", the errors disappear. Gr. Matthijs

Performance and fonts issues

Hello, I wonder -- why wait up to 5sec to (re)compile a single page on a Core 2 Duo machine? Let's look at the end of the log file for my simple, one-page document: mkiv lua stats : input load time - 0.000 seconds mkiv lua stats : stored bytecode data - 184 modules, 45 tables, 229 chunks mkiv lua stats : node list callback tasks - 4 unique tasks, 3 created, 75 calls mkiv lua stats : cleaned up reserved nodes - 23 nodes, 9 lists of 1410 mkiv lua stats : node memory usage - 20 glue_spec, 2 dir mkiv lua stats : used backend - pdf (backend for directly generating pdf output) mkiv lua stats : loaded patterns - en:us:pat:exc:2 mkiv lua stats : startup time - 0.531 seconds (including runtime option file processing) mkiv lua stats : callbacks - direct: 288, indirect: 3681, total: 3969 mkiv lua stats : loaded fonts - 37 files: lmmono10-regular.otf lmmono12-regular.otf lmmono8-regular.otf lmmono9-regular.otf lmroman10-bold.otf lmroman10-regular.otf lmroman12-bold.otf lmroman12-regular.otf lmroman7-bold.otf lmroman7-regular.otf lmroman9-bold.otf lmroman9-regular.otf lmsans10-regular.otf lmsans12-regular.otf lmsans8-regular.otf lmsans9-regular.otf eufb10.tfm eufb7.tfm eufm10.tfm eufm7.tfm msam10.tfm msam7.tfm msbm10.tfm msbm7.tfm lmex10.tfm lmmi10.tfm lmmi12.tfm lmmi7.tfm lmmi9.tfm lmmib10.tfm lmmib7.tfm lmsy10.tfm lmsy7.tfm lmsy9.tfm minionpro-bold.otf minionpro-it.otf minionpro-regular.otf mkiv lua stats : fonts load time - 2.750 seconds mkiv lua stats : result saved in file - garden_in_the_rain.pdf mkiv lua stats : luatex banner - this is luatex, version beta-0.43.0-2009083017 mkiv lua stats : control sequences - 29475 of 165536 mkiv lua stats : current memory usage - 147 MB (ctx: 151 MB) mkiv lua stats : runtime - 3.438 seconds, 1 processed pages, 1 shipped pages, 0.291 pages/second Startup time is 0.531 seconds. OK. Then, why on the Earth all these lmxxx fonts are loaded, if I use Minion Pro typescript? 2.7sec... Hmmm. Seems like a root of evil. What can I do to get rid of all of them? My typescript: \starttypescript [serif] [MinionPro] \definefontsynonym [Serif][MinionPro-Regular.otf][features=default] \definefontsynonym [SerifBold][MinionPro-Bold.otf][features=default] \definefontsynonym [SerifItalic][MinionPro-It.otf][features=default] \definefontsynonym [SerifBoldItalic][MinionPro-BoldIt.otf][features=default] \stoptypescript \starttypescript [MinionPro] \definetypeface [MinionPro][rm][serif][MinionPro][default] \stoptypescript Regards, Vyatcheslav

Small caps problem/bug with some fonts
by Mika Ritola 22 Sep '09

22 Sep '09

Hello all, For some reason, the snippet below outputs 'ThOMAS' instead of 'THOMAS.' This seems to be font dependent; at least Adobe Jenson Pro and Adobe Garamond Pro produce 'Th,' while the other fonts that I've tried produce 'TH', as expected. I don't know whether the bug exists in the fonts themselves or in the way they are handled by ConTeXt or the Simplefonts module, or possibly some other part of the system. In any case, could you suggest a work-around, please? I'm using ConText version 2009.09.16 20:07 and Simplefonts version 2009.09.15. \usemodule[simplefonts] \setmainfont[Adobe Jenson Pro] \starttext {\sc Thomas} \stoptext Thanks in advance, Mika

setting variable on cmd-line
by Peter Münster 21 Sep '09

21 Sep '09

Hello, I've a little feature request: It would be nice, to have a command line option like "--setvalue x=y" or similar for the "context" command to define a variable for the job. Modes are already very nice, but often I need just one value for conditional compiling a document instead of many binary switches. Perhaps the "context --arguments" option is what I'm looking for, but I didn't find how to use it. Another option would be, to make the name of the result-file ("context --result=...") available, for example as "\resultname". Cheers, Peter -- Contact information: http://pmrb.free.fr/contact/
