Hi, I had a look at sort-lan.lua, here are lines 156--158: ['y'] = 38, -- y ['z'] = 49, -- z [uc(0x017E)] = 40, -- zcaron I guess the correct value for “z” should be “39”? Philipp -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments

Problem with \c{a}
by Mikael Persson 22 Mar '10

22 Mar '10

Dear list, I cannot get \c{a} to work in mkiv. Small test file: \starttext \c{c} % works both in mkii and mkiv \c{a} % works only in mkii (in mkiv I get nothing) \stoptext Is there a fix for this? I would not like to use the unicode char directly in the file (because I have this inside a bib-entry and I'd like to keep the bib file without such constructions.) Best regards, Mikael

More on Adobe Multiple Master fonts (not quite dead yet:-)
by Graham Douglas 21 Mar '10

21 Mar '10

Dear Hans + Taco I have a question about "Minion Expert" fonts. I do have a copy of Idris's paper on this very topic but I'm not sure if this is still the way to install fonts via MKIV/LuaTeX. I'll give some background on what I'm doing, so my apologies to the list for the long post. [Note: happy to write this up in full for the Wiki at some point if of more general interest] I have been able to create hundreds of Minion instances and (with the excption of "Expert") successfully install them in Context --- works really very well. I have tested the PDF output with 500+ separate instances embedded, all seem to work perfectly --- provided the mmpfb settings are right. The resulting instances/fonts (.afm, .pfb) are output directly into the Context tree with names like MinionRegularRoman_wt525_wd600_op20.[afm|pfb] Generally the names are formed as follows: Minion[Variety][Angle]_wt[num]_wd[num]_op[num] Variety = one of Expert,Regular,Smallcaps Angle = one of Roman,Italic After refreshing the font lists/file name databases all instances can all be accessed through commands like this \definedfont[MinionRegularRoman_wt450_wd600_op10 at 12pt] --- I intend to write a typescript to set them up properly but these are early days for me with Context. I'm hoping that the above font naming convention will allow me to write a quite flexible set of typescripts... eventually. The only one that does not work is the Expert font (no surprise I guess) As mentioned, my scripts output the fonts directly into the Context tree, for Regular,Smallcaps varieties that's all I have to do. Wonderful! So, to the "Expert" variety... Clearly, this font has a "non standard" encoding vector which is causing the problm (I guess). The AFM records EncodingScheme FontSpecific If I install instances like MinionExpertRoman_wt350_wd450_op10.afm then run the minimal example \starttext \definedfont[MinionExpertRoman_wt500_wd450_op10 at 12pt] This is an interesting test. 1234567890. filling, fill. ABCDEF. \stoptext When I run this for the firt time I get !load afm : reading c:/Context/tex/texmf-context/fonts/afm/minion/MinionExpertRoman/MinionExpertRoman_wt500_wd450_op10.afm !load afm : unifying c:/Context/tex/texmf-context/fonts/afm/minion/MinionExpertRoman/MinionExpertRoman_wt500_wd450_op10.afm !afm glyph : assigning private slot U+F0000 for unknown glyph name Acutesmall !afm glyph : assigning private slot U+F0001 for unknown glyph name nineoldstyle <snip> The resulting PDF is blank, apart from the dot and commas in the sample text "This is an interesting test. 1234567890. filling, fill. ABCDEF." So, finally to my question: what additional work do I need to do to fully integrate the Expert fonts to access some of the nice features of these fonts? Warm wishes Graham =======

Table of contents
by Alain Delmotte 21 Mar '10

21 Mar '10

Hi! I have two question about table of contents. 1) is it possible to have the toc at the end of the document. I tried to place \placecontent or \completecontent at the end and it didn't work; I only managed to have the toc at the beginning of the document. 2) If I define my own header (like in ConTeXt an excursion: 5. Headers) and so, for example, replacing \section by \myheader, which has a section level, the table of content is empty! If the information is in another document, please give me a pointer, thanks!

stripping space from xml nodes
by Hans van der Meer 21 Mar '10

21 Mar '10

In order to have (1) <abc>text</abc> behave the same as (2) <abc> text </abc> one can use \xmlstripped{node}{lpath}. However, the drawback is that I found there is no further node expansion of inner content. For example \xmlstripped with <abc>text <somenode/> text</abc> returned "text <somenode/> text". I have already reported earlier that I could not see \xmlstrip{node} {lpath} work as I understood it. That is, it seems to me that in: \startxmlsetups xml:abc \xmlstrip{#1}{} \stopxmlsetups this would strip the spaces from (2) above. It didn't do that, while I also tried of course \xmlstrip in the node enclosing <abc>, also to no avail. As a work around one finds: \startxmlsetups xml:abc \ignorespaces % removes spurious space before \xmltext{#1}{} \unskip % removes spurious space after \stopxmlsetups but it is the sort of a kludge I do not feel happy about, apart from the fact that either this has to be put everywhere or another macro layer put around all \xml's suffering. This boils down to two questions: (1) how about \xmlstrip? (2) is the observed behaviour of \xmlstripped (not expanding nodes below) as it should? As Hans Hagen mentioned before he would have I look into it, I kindly ask if he already has found time for this. Hans van der Meer

Different behaviour
by Alain Delmotte 21 Mar '10

21 Mar '10

Hi! I did find a different behaviour for the same command. In: 1] \starttext 2] \defineenumeration 3] [remark] 4] [way=bysection,location=top, 5] text=Remark, 6] inbetween=\blank, 7] after=\blank] 8] \remark In the early medieval times Hasselt was a place of pilgrimage. %point 1 9] \subremark Nowadays the {\em Heilige Stede} is closed again. %point 2 10] \subremark Nowadays the {\em Heilige Stede} is closed again. %point 3 11] 12] Remarquer la possibilité d'avoir des sous-numéros. 13] 14] \remark In the early medieval times Hasselt was a place of pilgrimage. %point 4 15] 16] \subremark Nowadays the {\em Heilige Stede} is closed again. %point 5 17] 18] Aussi les \type{\startremark...\stopremark}. 19] 20] \remark In the early medieval times Hasselt was a place of pilgrimage. %point 6 21] 22] \subremark Nowadays the {\em Heilige Stede} is closed again. %point 7 23] 24] \subremark Nowadays the {\em Heilige Stede} is closed again. %point 8 25] 26] \stoptext ------------------------ This works (no empry line before points 1, 2, 3; empty lines before the others) If I suppress the line before any of the points 4, 5, 6, 7 or 8 I get an error Runaway argument for the line of point 8! Suppressing *after* point 3 or point 5 also gives an error. In fact, it looks like there should be an empty line after the \remark or \subremark, but not for the first group! (NB. I did add the line number to avoid misunderstanding going from a Windows CRLF to other CR or LF) Alain

Adobe Multiple Master Fonts: support in LuaTeX?
by Graham Douglas 19 Mar '10

19 Mar '10

Hi All A few (ie > 10) years ago I purchased the MinionMM and MyriadMM Multiple Master typefaces from the long-defunct Adobe Type on Call. I have the full set including the expert fonts. They were really quite expensive so I would really like to find out if they are (or will be) supported by LuaTeX. Having installed FontForge (FF) on my PC I note that FF certainly supports them. So, I was wondering if MM technolgy, even though it is kinda obsolete, is or will be supported? For sure, you can certainly create individual instances via Akira's port (thank you Akira) of the LCDF Typetools (specifically mmafm, mmpfb) http://www.lcdf.org/type/index.html I've tried this and the resulting PFB/AFM files definitely work with Context --- even got my first very simple typescript to work :-) I would be very interested to know the current support, or planned support, for being able to create "multiple master instances" on the fly. For sure, I appreciate that MM support may just not be worth the effort because the technology is "old" and few people are interested in this? Or it may be that it's too much work to create and then install instances on the fly. But the fonts are nice... and cost a lot :-( Warm regards Graham

Using external libraries in LuaTeX
by Graham Douglas 19 Mar '10

19 Mar '10

Dear All In a the recent Luatex 0.46.0 announcement http://tug.org/pipermail/luatex/2009-November/001118.html experimental support for loading external libraries was reported. I am running Windows Vista with ConTeXt ver: 2010.03.12 19:49 MKIV fmt: 2010.3.16 int: english/english with LuaTeX, Version beta-0.51.0-2010031309 (rev 3479) I have also downloaded Lua 5.1 from http://luaforwindows.luaforge.net/ and so have Lua5.1.dll installed. This distribution has a number of interesting extenal libraries (ie DLLs) that I would like to try out with LuaTeX. If I can make progress I would be happy to document and write-up my experiments for posting on the Wiki in case they may be of interest to others. I should say that my coding skills are somewhat rusty as I've been away from programming/TeX for a few years... so do please excuse my "simplistic" questions :-) So, I was wondering if anyone has a minimal example they would be kind enough to share, or can give me a few pointers/guidelines so that I can start experimenting. In particular, I'm interested to call external libraries and inject the output from an external library into TeX for typesetting. For example, is it possible to load a library once, keep it loaded and access the library functions from different commands during the TeX run? In outline... --- run some code to load the library (initialisation) --- keeping the library available --- some commands\definitions to accss library functions eg \calltolibrary{....) --- make callsto library and pass the output into TeX for typesetting I would be very grateful for any guidance/help that can be offered. Warm wishes to all Graham
