I am setting up a project structure for a new journal and I want to use a structure like the one in this answer. However, instead of using document:start I tried \startsetups component:start, but no results.

My structure looks like this:

  • test.tex
\startproject *
\environment test_env

\product test_prod

  • test_env.tex
\startenvironment *


\startsetups component:start
    This should appear somewhere!

  • test_prod.tex
\startproduct *
\project test

\component test_comp

  • test_comp.tex
\startcomponent *
\product test_prod
%\project test

    That's because there is no component:start. You could add \directsetup{component:start} before every \startcomponent or more programatically \prependvalue{startcomponent}{\directsetup{component:start}} (and likewise \appendvalue{stopcomponent}{\directsetup{component:stop}}).

  • Where can I learn about these things? It's not really clear to me why the mechanism works with \startdocument but not with \startcomponent. For me this looks similar enough.

    I just grepped the ConTeXt source tree for component:start and nothing came up. Then I also looked at the definition of \startcomponent to find that there also isn't any other setup code called before. May 8, 2019 at 3:11

  • Yes, please. ...

There is not component:start. The idea is that you only set metadata for the whole document once when you place \startdocument. If you still want to insert your setups before \startcomponent you can write


or more programmatically


Of course this has to be placed before the first \startcomponent.
