Well, Hans claimed this could be done without virtual fonts, and I was trying to follow his implementation. Could you tell me where the default mapping of OldStyle to MathItalic is documented/implemented in the sources? Maybe I could make a similar mechanism for my normal-expert dyad.

good-looking tables in context
by Eckhart Guthöhrlein 10 Apr '05

10 Apr '05

Hi all, I have to present a lot of numerical data in tables. However, I don't know how to achieve aesthetically pleasing results in context. (Ex)-Latex users may know the booktabs package which is a great help in this respect. I would like to achieve the same in context now. I have attached a small example file (source and pdf). Let me draw your attention to the most important points: - There are rules of different thickness for top, bottom, and middle rules. - The spacing between rows before / after / around the rules is nicely adjusted automatically. - Rules not spanning all columns, like the one in the header, can be trimmed at the left and the right so that they do not extend entirely to the start/end oft the first/last column. I think all three features are essential for convenient typesetting of tables with acceptable output. How can I produce this in context? I am aware of the different table mechanisms. As far as I have seen in the available documentation, none of them is currently suited for what I want. Or am I wrong? I hope so, and I am grateful for your hints and comments. Regards, Eckhart

Ok, but Hans explicitly claimed to have done this for Latin Modern without virtual fonts, only encoding trickery (I'll c if I can find that message). Actually, I was really surprised when Hans said he could do this without virtual fonts, and have always been eager to learn the trick;-> With Alan Hoenig's help almost 2 years ago I contructed a complete virtual font for old style cmr using virtual fonts; I guess I can do that again (though with a non-TeX font I'm scared;-> I'll read your how-to). On the other hand, how will TeXFont handle virtual fonts? What does TeXfont need to do this correctly? Or do we just forget about TeXFont? Thanks again!

Encoding and mapping glyphs from an expert font
by Idris Samawi Hamid 09 Apr '05

09 Apr '05

[To all the font experts out there: I really need your help!! I have spent at least 12 hours (!) trying to make this work but to no avail.] Dear gang, I have two fonts (actually, lots more but let's keep it simple), one normal and one expert. I did the following: 1. installed the regular font with texnansi encoding. It works fine. It uses, say, texnansi-myfont.map, texnansi-lm.enc with lines like ==================================================== texnansi-raw-myfont MyFont 4 <texnansi-lm.enc <myfont.pfb ==================================================== 2. also installed the expert font with a private encoding. Basically the same as texnansi where they share characters in common. It uses, say, myfontx.map, myencoding.enc with lines like ==================================================== myencoding-raw-myfontx MyFontX 4 < myfont.pfb myencoding.enc ==================================================== 3. With a view to getting characters from my expert font, I carefully studied as best as I could the implementation of old style figures in lmr, which involves mappings to cmmi10. This is what I could figure out: Activating old style is done by ==================================================== \usetypescript [modern][texnansi] \usetypescript [map] [latin-modern-os] [texnansi] \usetypescript[latin-modern][texnansi] \setupbodyfont[latin-modern] ==================================================== There appear to be two main things going on (but I think I'm missing something): a. loading a map file: ==================================================== \starttypescript [map] [latin-modern-os] [ec,texnansi,qx,t5,pl0,il2] \loadmapfile[\typescriptthree-os-public-lm.map] \stoptypescript ==================================================== Since I'm using texnansi, I looked at texnansi-os-public-lm.map . It contains lines like ==================================================== texnansi-lmb10 LMRomanDemi10-Regular <texnansi-os-lm.enc <lmb10.pfb ==================================================== So I designed an encoding file myfont-plus.enc almost identical to texnansi-os-lm.enc, containing, e.g., old style numerals from my expert font. I edited the myfont map files to exactly match the syntax of both texnansi-os-public-lm.map and texnansi-public-lm.map So for my fonts I have a total of three map files: \loadmapfile[texnansi-myfont.map] % for regular font \loadmapfile[myencoding-myfontx.map] % for expert font \loadmapfile[texnansi-x-myfont.map] % for mapping minion reg to minion ex >From this point I am lost. I set up my type-myfont.tex to load these maps. I can get myfont to work alone, and myfontx to work alone, but I cannot map characters from myfontx to myfont. By the way, I still don't understand how placing, e.g., /zerooldstyle in the respective /zero position in an encoding file will instruct LatinModern to pick up the glyph from cmmi10. In, for example, ==================================================== texnansi-lmb10 LMRomanDemi10-Regular <texnansi-os-lm.enc <lmb10.pfb ==================================================== How does ConTeXt know that /zerooldstyle is to be mapped to cmmbi10? I must be missing something....

Hi Adam, Thank you very much for explaining this. After some more research, I actually finally figured it out a few hours ago (including the examination of type-ini), but felt embarrased at bothering the list yet again about it;-) At least I'm "back in business" once again:-) Hopefully my hours of struggling with things like this will pay off in the end...

RE: [NTG-context] Defining new font switches (solved?)
by Idris Samawi Hamid 08 Apr '05

Ok, I think I have come closer to understanding the \definestyle problem. The problem (bug?) is in \definetypeface. Consider the following test typescript: ==============type-testlm.tex=============== \definestyle [mvmystyle] [\mv] [] \starttypescript [serif] [mystyle] [name] \definefontsynonym [MySerif] [cmcsc10] \definefontsynonym [Serif] [MySerif] \stoptypescript \starttypescript [serif] [mystyle] [size] \definebodyfont [20.7pt,17.3pt,14.4pt,12pt,11pt,10pt, 9pt,8pt,7pt,6pt,5pt,4pt] [rm] [tf=Serif sa 1, mv=Serif sa 1] \stoptypescript \starttypescript [MYTest] \definebodyfontenvironment [mytest] [default] [interlinespace=2.8ex] \definetypeface [mytest] [rm] [serif] [mystyle] %[mystyle] [encoding=default] \stoptypescript ============================================== Now consider the following test file: ===========test.tex================ % output=pdf interface=en \usetypescriptfile[type-testlm] \usetypescript[MYTest] \setupbodyfont[mytest,12pt] \starttext {\tf This is a test.} {\normal This is a test.} {\mv This is a test.} {\mvmystyle This is a test.} \stoptext ================================= Consider the \definetypeface line. If we leave the comment in place, then the \tf switch will work (and give us small caps) while the \mv switch will give an undefined control sequence. If we uncomment the last two options in \definetypeface, then \mv will also work. Why do predefined switches like \tf work with 4 options while user-defined style options fail? Is this a bug or feature (seems inconsistent)? Thnx in advance as always, and happy weekend Idris ============================ Professor Idris Samawi Hamid Department of Philosophy Colorado State University Fort Collins, CO 80523

natural tables flaw: extra space
by Eckhart Guthöhrlein 08 Apr '05

08 Apr '05

Hi, consider the following example \starttext \setupTABLE[frame=off] \setupTABLE[row][first][topframe=on,rulethickness=1mm] \bTABLE \bTR \bTD 1,1 \eTD \bTD 2,1 \eTD \eTR \bTR \bTD 1,2 \eTD \bTD 2,2 \eTD \eTR \eTABLE \stoptext In the first cell, extra space is added before the entry. I guess it's 1mm from the left frame which should be off, so the space shouldn't be there. Or is it a feature? Greetings, -- Eckhart
