A couple of questions on math customizing.
by Brooks Moses 11 Jul '05

11 Jul '05

I'm working on doing my own math alignment routines. After a lot of poking about in core-mat.tex, I came to the conclusion that \startinnermath and \stopinnermath were probably the things to modify, and the "most polite" way to do that was by defining my own alignment name. So, the following does what I want for a test case: (Note that \defineinnermathhandler is a shortcut to define versions of \startinnermath and \stopinnermath corresponding to the given alignment.) \starttext \defineinnermathhandler{test} {\let\doplaceformulanumber\empty} {} \setupformulas[align=test] \placeformula{a} \startformula c^2 = a^2 + b^2 \eqno{\formulanumber} \stopformula \stoptext First, if I want \stopinnermath to handle the formula number, I have to somehow turn off the \doplaceformulanumber that gets called at the beginning of \dostopformula. Redefining the macro to \empty in \startinnermath works, but it seems a bit inelegant. Is there a better way? Second, if I move that \eqno{\formulanumber} up into \stopinnermath, as in the following sample, I get an error about "\eqno not allowed in math mode", despite the fact that it seems to be doing the exact same thing as the previous example. \starttext \defineinnermathhandler{test} {\let\doplaceformulanumber\empty} {\eqno{\formulanumber}} \setupformulas[align=test] \placeformula{a} \startformula c^2 = a^2 + b^2 \stopformula \stoptext Then, if I enclose the \eqno in an if statement borrowed from the just-erased definition of \doplaceformulanumber, it works again: \starttext \unprotect \defineinnermathhandler{test} {\let\doplaceformulanumber\empty} {\eqno{\formulanumber}} {\doifelse \@@fmlocation \v!left% {\normalleqno {\formulanumber}}% {\normalreqno {\formulanumber}}} \protect \setupformulas[align=test] \placeformula{a} \startformula c^2 = a^2 + b^2 \stopformula \stoptext What's up with that, and what do I need to do to be able to put a bare \eqno in the \stopinnermath macro? Thanks! - Brooks

ConTeXt in use
by Arun Swarup 10 Jul '05

hi, I see many books typeset with LaTeX, but what about ConTeXt? I haven't seen any books typset using ConTeXt (excluding ConTeXt manuals, of courz :P). Have you? -arun ___________________________ and what i used to think was me is just a fading memory. - nine inch nails ___________________________ __________________________________ Do you Yahoo!?

top and bottom options of \framed
by Radhelorn 10 Jul '05

10 Jul '05

Hello All! I have problem with \framed command: top and bottom seems to do nothing. According to manual this must produce top aligned framed text: \framed [height=4cm,top=,bottom=\vss] {framed text} Anything I type after top= and bottom= is lost in oblivion. ConTeXt even not warn about unknown commands in these options. -- Radhelorn <radhelorn(a)mail.ru>

Math bug: \tracemathtrue doesn't work without alignment.
by Brooks Moses 10 Jul '05

10 Jul '05

I was recently going through the core-mat.tex file (the one from teTeX 3.0.whatever-it-is) and trying out some of the examples given in the comments, and came across an odd little bug. Consider the following: \tracemathtrue \setupformulas[align=middle] \placeformula \startformula \fakeformula \stopformula This works fine. However, if I take out the "align=" argument from \setupformulas, the tracing boxes disappear. Meanwhile, I'm trying to figure out exactly how the alignment works in formulas, from a programming viewpoint. What's a good place to start with this? - Brooks

Hiding the content (drawing empty boxes?)
by Mojca Miklavec 08 Jul '05

08 Jul '05

Hello, Some TeX challenge (probably not solvable?): for gurus only. Is there a way to somehow \starthidden ... \stophidden, which would leave exactly the same amount of blank space as if the content would be typeset? Adam suggested to use transparent font colour, but this doesn't solve the problem as this won't stop the images, frames and nested \color[red]{font color changing commands} being displayed. I tried to adapt the macro \demobox from the TeXBOOK which processes token by token and draws an empty box instead of that token. It works perfectly as long as there is only plain text between the braces, but as soon there is something more complex, it breaks. This behaviour is probably to be expected, but I have no idea how to let all the commands do what they are expected to do and only prohibit placing any boxes with some content. Thanks, Mojca

How to override a font in a typescript
by Giuseppe Bilotta 08 Jul '05

08 Jul '05

Practical example: when I set up palatino, the typescript file set 'modern' as the typeface (which again tries to load the lm files :)) Assume now that I want to overrule that choice, and only that choice. Can I do this from within my source file? -- Giuseppe "Oblomov" Bilotta

Preliminary support for the Luxi typeface
by Giuseppe Bilotta 08 Jul '05

08 Jul '05

I couldn't find the appropriate typescript definition in ConTeXt, so here's the initial stuff: \starttypescript[mono][luxi][\defaultencoding] \definefontsynonym[Luxi] [\defaultencoding-ul9r8a] [encoding=\defaultencoding] \definefontsynonym[LuxiBold] [\defaultencoding-ul9b8a] [encoding=\defaultencoding] \definefontsynonym[LuxiOblique] [\defaultencoding-ul9ro8a][encoding=\defaultencoding] \definefontsynonym[LuxiBoldOblique] [\defaultencoding-ul9bo8a][encoding=\defaultencoding] \stoptypescript % Maybe should map Slanted, not Italic \starttypescript[mono][luxi][name] \definefontsynonym[Mono][Luxi] \definefontsynonym[MonoBold][LuxiBold] \definefontsynonym[MonoItalic][LuxiOblique] \definefontsynonym[MonoBoldItalic][LuxiBoldOblique] \stoptypescript Of course there's the usual Berry name mapping needed if you only have the LaTeX metrics, which go to the regular expression ul9[rb]o?8[artc] as usual. -- Giuseppe "Oblomov" Bilotta

Why does ConTeXt try to load Latin Modern?
by Giuseppe Bilotta 08 Jul '05

08 Jul '05

I just upgraded my MiKTeX and ConTeXt, and I found out that ConTeXt tries to load Latin Modern regardless of my choice. Example document: """ \setupbodyfont[ppl,rm,12pt]% \starttext Hello, world! \stoptext """ Discarding my \setupbodyfont, ConTeXt tries to load ec-lmr12. Suggestions? -- Giuseppe "Oblomov" Bilotta
