doing some tests I discovered two interesting facts.
The first is that commands \starttext and \stoptext do not behave as a group.
Minimal example (tested on TL2015, TL2016, TL2017, current CTX from the Garden):
\starttext text \starttext \bf text \stoptext text % this text is in bold, too. \stoptext
Is this the expected behaviour, or not?
Opening a group with \starttext makes no sense because there is nothing after \stoptext. The possibility to nest \starttext is necessary when you \startproduct etc. where components can be be documents on its own and this means \startcomponent includes \starttext in its definition.
The second interesting thing is that the unbalanced document is compiled without protests:
Minimal example #1 (tested on TL2015, TL2016, TL2017, current CTX from the Garden):
\starttext text % in this case, the "text" is shipped out
Take a look at the command line when you process a file and you should see something like this: mtx-context | run 1: luatex --fmt="[...]/cont-en" --jobname="test" [...] --c:input="./test.tex" [...] "cont-yes.mkiv" As you can see the luatex engine processes the file cont-yes.mkiv and not your document which put as argument to context. Your document is just read by cont-yes.mkiv and at the end of the document ConTeXt inserts an extra \stoptext which is ignored when your document is valid (equal number of \starttext and \stoptext).
Minimal example #2 (tested on TL2015, TL2016, TL2017, current CTX from the Garden):
text % in this case, the "text" is not shipped out \stoptext
The reason why no text appears is that ConTeXt doesn’t load the default fonts untill \starttext. The reason for this is to is a gain in speed and you save resources. You can test this by adding \setupbodyfont[modern] at the begin of your example. Wolfgang
