Dear List,

I was reading workflow-mkiv and have found the '--errors' and '--noconsole' arguments which seemed quite helpful since, according to the documentation, "show errors at the end of a run" and "disables logging to the console" while "error reporting mentioned in the previous section will never be silenced". But when I run 'context --errors' for the following document

    \setuppagenumbering[footer]
    \starttext
    hi
    \stoptext

the message

    setup           > error in line 1, namespace 'pagenumbering', key 'footer,'

still lies in the middle of a bunch of messages and is not shown in the end. When I add '--noconsole' to the arguments, the error disappears along with all the other messages.

--errors adds extra information to the log, try the following example with and without the option

\usemodule[unknown]

\starttext
\stoptext
