Projects?

Projects?

[Michal Kvasnicka]

Good morning.

After long use of ConTeXt I've read the chapter two of the Great English

Manual, and I've found projects. Let me ask some questions, please.

1) Is it possible to have more than tree levels (e. g. can component
load
other component?)? (A theoretical question perhaps. :-)

2) I've read about \startlocalenvironment[names]
...\stoplocalenvironment.
How is it invoked?

3) I'd like components to be styled in a different way if they are
standing
alone than if they are typeset in the whole project. How to do it? Via
\startlocalenvironment? How?

4) What the mechanism does precisely?

Many thanks,
Michal Kvasnicka

indeed components can components

automatically, when an environment has local ones, these are only invoked
when the calling project/product/component matches the comma separated list

in many cases, modes are more handy, like in: 

\startmode[paper]
  \setuppapersize[A4][A4]
\stopmode

\startnotmode[paper]
  \setuppapersize[S6][S6]
\stopmode

to be used with 

texexec --mode=paper

the project/etc mechanism [when set up ok] can be used to run individual
components. It originates in educational projects where we wanted to have
common environments, several products [student/teacher/examns/etc] with for
instance student materials split up in components. That way we can process
an individual component in the framework of a product in ... of a project
etc. Also, it makes possible to define several products using similar
components but under for instance a different environment. Say that you
want examns with and without answers, in which case the version with
answers can have answer blocks enabled [you may want to read the chapter
about moving blocks around and reusing text].

Actually all our a bit bigger projects have their files organized using
this project mechanism [for instance qa manuals with some 15  products of
which some 10 are composed of combinations/selections of hundreds of
components]. Actually, it's a rather old mechanism which I should extend /
update a bit, but it works ok.
