What keys and values are available for the third, and what they mean. Thank you, but by "the first two arguments", I mean 1 and 2 of: \definefontfeature [1][2][3]. For example, in \definefontfeature[smallcaps][smallcaps][script=latn] I don't know what "[smallcaps][smallcaps]" is doing. > > 3.

(And, by the way, my font has Greek and Cyrillic as well---why disable oldstyle in them?) I think that leaves me with a command or variable or something called "oldstyle", which I could include in the text. My first guess would have been that it's "\oldstyle", but, later in your code snippet, I see "\setff{smallcaps}" and "\addff{smallcaps}". There's no telling what the difference is. So, I'm left guessing that \definefontfeature[oldstyle] [oldstyle] [script=latn] creates a possible argument for \setff{} and \addff{}, whatever they are. They might be the commands for font switching in the text. Since the code snippet isn't a human explanation, however, I can't tell--- I can only make wild guesses. > > 4.

Schmitz: > This is not to disparage Wolfgang's great simplefonts module, but I learnt setting up fonts the old-fashioned way (with typescripts), > so I will give a few explanations about this approach. Most of what you want can be achieved easily. I have Garamond Premier myself, and this is how I set it up: Thank you, this is very encouraging. I used to do this with otftotfm and .fd files, so it's not totally alien to me. I just need to grasp the syntax of the Context commands. I've been pouring over your example. There are a few points I still don't understand. ... > Next step: we set up the "normal" and smallcaps font: > \starttypescript [serif] [garamondprem] > \definefontsynonym [Garamond-Roman] [name:garamondpremierpro] [features=myroman] > \definefontsynonym [Garamond-Bold] [name:garamondpremierprobold] [features=myroman] > \definefontsynonym [Garamond-Italic] [name:garamondpremierproitalic] [features=myroman] > \definefontsynonym [Garamond-Bold-Italic] [name:garamondpremierprobolditalicc] [features=myroman] > \definefontsynonym [Garamond-SmallCaps] [name:garamondpremierpro] [features=mysmcp] > \stoptypescript > > \starttypescript [serif] [garamondprem] > \definefontsynonym [Serif] [Garamond-Roman] [features=myroman] > \definefontsynonym [SerifItalic] [Garamond-Italic] [features=myroman] > \definefontsynonym [SerifBold] [Garamond-Bold] [features=myroman] > \definefontsynonym [SerifBoldItalic] [Garamond-Bold-Italic] [features=myroman] > \definefontsynonym [SerifCaps] [Garamond-SmallCaps] [features=mysmcp] > \stoptypescript I don't understand the syntax of \starttypescript. It doesn't appear in the manual. It occurs twice in the "typography" document. In both cases the first argument appears to be the name of the typescript. In one example, there is only one argument, and in the other example, the second argument appears to be a list of encodings. Since everything is now utf-8, I guess that could be forgotten. So, in your example here, I take "serif" to be the name of both typsecripts, but I don't know what [garamondprem] is doing. It's never spelled out, but from looking at examples of \definefontsynonym [1][2] in the docs, I think it means something like "what we used to call 2 we can now call 1", i.e., telling the machine to replace instances of "1" with "2". If this is the case, your third arguments above just seem to apply your features to the fonts referred to, which makes sense. I don't see, though, why this has to be done twice, and with an extra layer of misdirection. E.g., instead of: \definefontsynonym [Garamond-Roman] [name:garamondpremierpro] [features=myroman] \definefontsynonym [Serif] [Garamond-Roman] [features=myroman] why not just: \definefontsynonym [Serif] [name:garamondpremierpro] [features=myroman]? I think the purpose of the above step is to connect identifiers like "Serif" to a qualified font file. > Finally, define your first typeface: > > \starttypescript [GaramondPrem] > \definetypeface [GaramondPrem] [rm] [serif] [garamondprem] [default] > \stoptypescript I think this is a typescript called GaramondPrem that contains a typeface called GaramondPrem. It seems a little redundant that they have the same name. I know that the typescripts are referred to by \usetypescript, but I don't know where typefaces are referred to, so maybe it's just a dummy argument. The "[rm]" seems to be what links this to the font switching command, and the "[garamondprem]" obviously refers to both the typescripts you defined above. I don't understand what the "[serif]" is doing. In the typography manual, Hans says, "The third and fourth arguments to \definetypeface are pointers to already declared font sets; these are defined elsewhere." I think by "font set" he must mean a typescript like garamondprem, but I don't know where the font set (typescript?) "serif" is or why two font sets need to be pointed to. The same typography document goes on to explain the fifth argument: "The fifth argument to \definetypeface specifies specific font size setups (if any), these will be covered in section ?? in the next chapter." This is getting scary, but I'm hoping putting "[optical]" there will solve everything. > Next step: defining a typeface with superior numbers for footnote references etc.: > \starttypescript [serif] [garamondpremupper] > \definefontsynonym [GaramondPremUpper-Roman] [name:agaramondproregular] [features=mysup] > \stoptypescript > \starttypescript [serif] [garamondpremupper] > \definefontsynonym [Serif] [GaramondPremUpper-Roman] [features=mysup] > \definefontsynonym [SerifItalic] [Serif] > \definefontsynonym [SerifBold] [Serif] > \definefontsynonym [SerifBoldItalic] [Serif] > \definefontsynonym [SerifCaps] [Serif] > \stoptypescript I think I follow you, up to the line: \definefontsynonym [SerifItalic] [Serif]. These last lines seem to say that if you're in bold or italic, that you should still use regular superior figures, but the font has its own bold and italic superiors. I think that's true of all the weight/shape/design size variations in the set. > \starttypescript [GaramondPremUpper] > \definetypeface [GaramondPremUpper] [rm] [serif] [garamondpremupper] [default] > \stoptypescript I'm confused about how [GaramondPremUpper] and [garamondpremupper] seem to be getting associated with [rm] and [serif] after they were already associated with [GaramondPrem] and [garamondprem]. I don't see how, when I now use \rm, the machine is going to know whether I mean garamondpremupper or garamondprem. The rest of the file seems straightforward. > OK so far? Thank you---that brought me a lot closer to understanding! after saving your example and running luatools --generate, I put the last lines in my test document and tried running Context on it in the usual way. I get the error: !undefined control sequence <recently read> \usetypescript l.12 \usetypescript [GaramondPrem] > 5.

Thanks again. ------------------------------ Wolfgang Schuster: > \setupalign[hanging,hz] Or maybe I'll try that. ------------------------------ Andreas Harder: >> 5.

Thank you. With this, the marks in the text look good, the ones at the bottom (with the footnotes) look absurdly small. I suspect this might be because they have been optically scaled down, not switched to the smaller design size, so they seem to evaporate. They might look better if they remain the same size as in the text, I'm not sure. ------------------------------ Wolfgang Schuster: http://wiki.contextgarden.net/Optical_Size Ahhh, the rest of my weekend. Thank you. -- m

colored column
by Wolfgang Werners-Lucchini 13 Mar '10

13 Mar '10

Hallo, can someone explain how to write a table column in color, please? The following example worked in 2006 but is not working anymore: \starttext \starttable[o1|\{C{red}|] \VL red \VL\SR \stoptable \stoptext Wolfgang Schuster posted last year the following example: \NewFormatKey W#1% {\ReadFormatKeys b{\localstartcolor[#1]\{} a{\}\localstopcolor}} \starttable[o1|W{red}c|] \VL red \VL\SR \stoptable But this results in printing '{red}' in red, not 'red'! And this variant paints the following vertical line in red too: \NewFormatKey W#1% {\ReadFormatKeys b{\localstartcolor[#1]} a{\localstopcolor}} \starttable[o1|W{red}c|] \VL red \VL\SR \stoptable So, how can I do the job?

That _did_ work, after I got rid of an \os (I used it because I saw it in the manual). The command \definefontfeature intrigues me greatly. I wonder if it could solve all my problems. I'd love to understand it so that I don't end up coming in here and asking you to write all my font setups line by line. I Googled it and found only a few scattered examples here and there, mostly from this list. I wish I could find an explanation of it written down somewhere. For example, I would very much like to know: 1. What the first two arguments do. 2. What keys and values are available for the third, and what they mean. 3. Once I have composed a \definefontfeature command, how do I use it in the text. 4. For example, I gathered that I needed a [default] [default] [...onum=yes...] to get oldstyle numerals by default, but what if I want to use some lining numerals here and there? \definefontfeature [lining] [lining] [...onum=no...] {\lining 123} doesn't do it. 5. How I could use the superior and inferior shapes in my font---like for the footnotemarks, for example? 6. Could I use \definefontfeature to set up the different design sizes of my font (I'm trying to use some standard Adobe fonts like Garamond Premiere Pro, which have design sizes), as well as its other features? 7. Maybe \definefontfeature is how I should turn on hz? I'm sure these things must be possible, but I'm stumped about how to find them out. -- m

streams
by Philipp Gesang 13 Mar '10

Hello all, the streams module could help typesetting my current work but all the examples fail in mkiv. (The output from mkii is impressive, though.) The snippets I tried are from the comments of http://source.contextgarden.net/tex/context/base/m-streams.tex and another one from the wiki http://wiki.contextgarden.net/Columns#Streams Here are the ConTeXt error messages, seems that \FlushLeftAndRight is the culprit but I don't really know where to start looking because the command sequences are not legible in this truncated form.

\xmlstrip?
by Hans van der Meer 12 Mar '10

12 Mar '10

I encounter difficulties in stripping the leading and trailing whitespace from a node. The following does not work for me, typesetting \CAST delivers an empty result: \def\Cast#1{\def\CAST{#1}} \startxmlsetups xml:case:cast \Cast{\xmlstrip{#1}{}} \stopxmlsetups nor do variants like: \Cast{xmlstrip{#1}{*}} \Cast{xmlstrip{#1}{/}} \Cast{xmlstrip{#1}{/cast}} What does work is: \Cast{\xmlflush{#1}} How do I proceed?

Antykwa Toruńska and dashes

Hi again, when using Antykwa Toruńska I have problems getting dashes rights. Example: -0<---------------------------------------------------------------------------- \usetypescript[antykwa-torunska] \setupbodyfont[antykwa] \starttext asdf -- adsf\par asdf --- adsf\par asdf--asdf\par asdf---asdf\par \stoptext -0<---------------------------------------------------------------------------- In output here (MkIV as of yesterday) the double/triple dashes are not concatenated to en/em dashes. Everything works fine with latin modern, schola, bonum etc. What's wrong? Philipp -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments

interlinespace confusion (MkIV)
by Steffen Wolfrum 12 Mar '10

12 Mar '10

Hi, I am totally confused by interlinespace usage in mkiv ... Please have a look at this torture test below: Setting bodytext to a tight interlinespace works by \setuplayout[grid=both]. But \chapter doesn't get right: Either you use \setuplocalinterlinespace, then you might get an extra space between the first and the second chaper line, or you use \setupinterlinespace, then the bodytext interlinespace gets disturbed. [btw: and how do I get a tight interlinespace in \chapter too?? here grid=both doesn't work ...] Could someone please help?!
