|\startlines ... \stoplines|
This allows the printing of text according to existing linebreaks within the text. The command itself takes no setups, but you can use \setuplines to indicate that you wish to preserve whitespace, or make it visible, as well as some other tricks; and if you find yourself using the same few setups throughout the document, you can make special-purpose environments using \definelines.
\startlines The lines are there! \stoplines
In Mark II, you can use [[Command/[space=on]|\[space=on]]] to make spaces visible.
\starttext \setuplines[space=on] \startlines All the white space will print ! \stoplines \stoptext
