I realized this. There would of course be only one "\starttopica...\stoptopica block" in my text. If I would like to use delimited texts in this manner for several different topics, I would simply give them different names. Each topic its own name, like [topicb], [topicc], etc. Like you would do if you wanted to use slightly different types of blockquote in your document. So my question: "Why can some identifiers, for example of figures, be used for internal references and others not?" remains unanswered. Best regards, Robert

Re: [NTG-context] [Dev-luatex] new/missing feature in luamplib

Some (simple) support for lua calls is on the (long term) agenda but not before the current mplib extensions project is done (i.e. the decimal calculation plugins). Calling lua in itself is not so much an issue; after all one can just do a \directlua inside a blob of mp passed to mplib (I do that all the time). For an lua 'primitive' in mplib (which then probably would just be called just 'lua') we first need to figure out: 1 - how to access mp internals (and that relates to the mentioned decimal extensions, as we might need to get and set) 2 - if and how we can share the state with the (main) tex lua instance 3 - how we want to print back to mp (like tex.[s]print) It's one of those feature we have discussed (maybe too) long ago, but because it has to be more than just (3) it never ended up first on the todo list (first finishing the main lib). The problem with these things is that it has to be mostly 'right from the start' in order not to conflict too much with long term usage). Anyhow, if you play with such things, best have something lua "mp.print(123)" Given mp's somewhat different parsing and expansion compared to tex there are also some conceptual issues involved. It also relates to input buffers (and file reading) and io is somewhat messy in mp and on the agenda for cleaning up. (Luigi Scarso has done this with metafont, so that might be a starting point for experimenting.)

Since they did not work, and you gave me a good solution, I trashed them. I kept the pdf's though, in which I included the source. So I can reconstruct the examples. I'll try to make it again tomorrow morning. I would be interested to learn what sort of errors I committed. Kind regards, Robert Blackstone

Layers
by Bill Meahan 06 Aug '12

06 Aug '12

Is there any issue with "stacking" layers on top of each other? What I want to do is create a newsletter nameplate consisting of a base layer containing a JPEG graphic of a logo, a partially-transparent layer above that to screen the graphic and a top layer containing the newsletter name in a large and fancy font ala' *The New York Times" & al. I've already created a nameplate in Inkscape and can simply place the resultant graphic but I'd like to do the whole thing in ConTeXt if I can as I could easily use the technique in other situations. I'll wikify any answers.

Another very useful tool for me.

Anyway, your and Wolfgang Schuster's advice give me all I need on this point. Kind regards, Robert Blackstone
