Basically, I would like a way to number the lines in a block of text, without resorting to verbatim mode.
I have tried
\definetyping[code][numbering=line,style=\tf] \startcode[step=5] Thus, I came to the conclusion that the designer of a new system must not only be the implementer and first large-scale user; the designer should also write the first user manual. \stopcode
but this preserves the whitespace; I would like ConTeXt to lay out the paragraph normally and then number the lines. The numbering does not need to be in the margin, but I would like to be able to skip every n numbers and use columns. The solution with
definetyping is quite close; I simply would like to avoid having to manually adjust line breaks and possibly have hyphenation.
I found Show the number of lines in margin for LaTeX, but that doesn't apply here, unless there is a ConTeXt equivalent (the wiki does not mention one and Google turns up nothing).
