selecting encoding for Unicode
by Gour 13 May '03

13 May '03

Hi! I have problem in displaying characters which are not in default ConTeXt encoding, eg. amacron, Amacron, Imacron, imacron .. My input is utf-8 and converted to ConTeXt with dbcontext package. In ConTeXt file I have: \chardef\utfunihashmode=1 and \enableregime[utf] and everything is fine, except that I don't know how to switch encoding to Unicode, so that the characters which are defined in e.g. \unic-001.tex can be displayed. I have tried with \useencoding [uc] but it doesn't work. However, when I put {\amacron} it is properly displayed - I conclude that ConTeXt understands the glyph name, but when it has to decode the same character as utf-8, it doesn't recognize it. Any hint?

Using \cal, \frak, \goth in math mode
by Giuseppe Bilotta 13 May '03

13 May '03

In ConTeXt, \cal, \frak and \goth (etc) are considered "text only" commands. To use them in math mode one has to use \gothing, \fraktur, \calligraphic etc, which make a temporary switch to text mode. This is contrary to the LaTeX expectations, where $\cal ABC$ makes all three letters calligraphic. How could such a thing be achieved in ConTeXt? -- Giuseppe "Oblomov" Bilotta

Toggle fields
by Sytse Knypstra 13 May '03

13 May '03

Dear ConTeXt users, In experimenting with (JavaScript) fields I tried the example on p. 11 in the up-to-date 1998/1 publication. I placed the check field not in the margin, but in the running text and discovered that \goto{Help}[JS(Toggle_Hide{Help})] does work if it is placed after \fitfield[Help], but that it does not work if it is placed before \fitfield[Help]. For the commands \goto{Hide Help}[HideField{Help}] and \goto{Show Help}[ShowField{Help}] their position relative to \fitfield[Help] does not matter. Would it be possible to make a command ToggleField, analagous to HideField and ShowField, whose position relative to \fitfield[Help} is not important? Thank you, Sytse %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Here is the complete example: \setupoutput[pdftex] \setupinteraction[state=start] \starttext \definefield[Help][check][Helpsetup][helpinfo][helpinfo] \setupfields[reset] \setupfield[Helpsetup][width=fit,height=fit,frame=off,option={readonly,hidden}] \definesymbol[helpinfo][\SomeHelpText] \def\SomeHelpText% {\framed [width=\leftmarginwidth,height=fit,align=middle,style=small, frame=on,background=color,backgroundcolor=white,framecolor=red] {Click on the hide button to remove this screen}} %\fitfield[Help] % if uncommented, all three \goto's work ok Now we can put the button somewhere and turn the help on or off by saying \goto{Hide Help}[HideField{Help}] or \goto{Show Help}[ShowField{Help}]. Although it's better to put these commands in a dedicated part of the screen. And try \goto{Help}[JS(Toggle_Hide{Help})]. \fitfield[Help] % \goto{Help}[JS(Toggle_Hide{Help})] does not work \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

ligatures?
by Adam Lindsay 12 May '03

12 May '03

TeXnicians, Once again, I'll stick my neck out showing my pure TeX ignorance. Are there ConTeXt commands for adding ligatures to the usual set (ff, fi, etc.)? Where in the chain are these characters (f + i) grouped and associated with the 'fi' character to be output? I'd like to be able to take advantage of some extended ligatures with my pro fonts, but it seems that if users have to enter the ligatures as \Thligature or whatever, they would be of very limited use. thanks in advance, adam -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Adam T.

Run ConTeXt from TexLive 7 CDROM and WinShell
by fa441907 12 May '03

12 May '03

Thank you to Maarten Sneep and Severin Obertuefer for help with my "Newbie cant get \externalfigure to work" It seems likely that problem arose because of some coding errors and also because I am using an old (1999) version of ConTeXt (part of 4TeX5.0 (NL Tug)). So I am trying to upgrade. I am now trying to run ConTeXt from TexLive 7 CDROM, TexLive says ... "Select a Tex-oriented editor" I chose WinShell To run Context, I made a WinShell User Defined Tool, as follows. In Options => General => Userdefined I did ... exefile = pdfetex ... cmd line = &cont-en When I run that tool I get One or more errors occurred! Please check the options! Now I am stuck again Your suggestions gratefully received Richard Hardwick

BUG in latest ConTeXt beta?
by Giuseppe Bilotta 10 May '03

10 May '03

Hello, I just downloaded the latest ConTeXt beta (2003.4.29), and I spotted a bug in lang-grk: the headtexts are defined for s!fi, not for s!gr (also, the package subtitles reads "Uralic" instead of "Greek" languages) ... -- Giuseppe "Oblomov" Bilotta

some questions on fonts
by Pablo Rodriguez 09 May '03

09 May '03

Dear ConTeXticians, I'm learning to use ConTeXt and the main problems I have with ConTeXt are related to fonts. I need to use utf-8 for my documents, since it is the proper way to handle polytonic Greek, Spanish and German in a single document without having to use strange input methods. I was told that it is possible to use utf-8 in ConTeXt (although Greek isn't defined for utf-8 yet), but I don't know how to enable this feature. Which command can I use utf-8 in my documents? (I know \enableregime, but it doesn't work with option unicode). Another problem is the fontencoding: I'd like to use the cm-super fonts, but if I try to use \setupencoding[default=ec] I get a recursive error with some documents (but this is probably due to the wrong document syntax) or the document fonts are the standard cm fonts in OT1 encoding, what is probably related to the last problem. I cannot invoke other fonts than \setupbodyfont[ber,pos]. I use the MikTeX total distribution and with pdfLaTeX all installed fonts work fine. With ConTeXt if I use \setupbodyfont[palatino], either I get an error from maketfm that doesn't know how to make ec-uplr8a or in other documents the variant palatino for bodyfont seems to be unknown. I'm extremely confused about how ConTeXt works with the installed fonts (probably I don't have the required knowledge to understand it) and actually I don't know how LaTeX mangages the available fonts, but it works. The above question is not how to install new fonts or even how ConTeXt manages fonts. The only thing I'd appreciate to know is the most simple procedure to invoke each installed font on my TeX distribution within ConTeXt. Many thanks for your help, Pablo

Magazine: OpenType Pro fonts in ConTeXt
by Adam Lindsay 09 May '03

09 May '03

Hi ConTeXters. I've finally documented some font support macros and typescripts that I've been working on. I collected the ideas in a MyWay magazine: <http://homepage.mac.com/atl/tex/OpenType.pdf> (782 Kb) The companion files are on the site as well: <http://homepage.mac.com/atl/tex/OpenType.zip> (25 Kb) A web page to hold all this stuff is forthcoming. The best way to describe what it does is with the abstract: This is a summary of issues encountered and solutions implemented in order to support some advanced OpenType features in ConTeXt. This article describes an accompanying package that addresses installation (using TeXFont), accommodating extended opticals families, and some ``pro'' font features. The extended character set afforded by pro fonts enables support for comprehensive small caps, old-style figures, and the use of greek glyphs to give workable math fonts. Although the typescripts and commands are described together, certain features (like variant encodings for TeXFont and the idiosyncratic method for creating new math fonts) can be used independently of the other features described. I hope this proves interesting, if not useful, to others. Cheers, adam -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Adam T.
