Command/startenvironment

A \startenvironment block contains setups that should be loaded when the file is invoked with \environment . The first argument (given without square brackets!) is the name, and can be anything as long as it's not empty (the filename is a common choice). This name is used by ConTeXt internally when keeping track of how often the environment has been loaded, and it is used when printing output to stderr/the log file, as follows:

used structure  > text: mytexfile
used structure  >   environment: myenvironment

Within a \startenvironment block, the commands \project, \product, and \component are ignored; other environments can be loaded using \environment.

% env_packed_items.tex
\startenvironment some_label
    \setupitemize[packed]
\stopenvironment

% myfile.tex
\environment env_packed_items

\starttext
    bla bla
    \startitemize
        \item
    \stopitemize
\stoptext
