Bar within math (amended)

Bar within math (amended)

Hello,

it seems that bar (even with option 'continue=yes') is not rendered in place of '~' within math. See the sample:

----
\definebar[MyBar][color=green,rulethickness=2.8,order=background,offset=1.5,continue=yes]

\starttext
  1 + 2 = \startbar[MyBar]3~kN\stopbar % OK

  $1 + 2 = \startbar[MyBar]3~\text{kN}\stopbar$ % No background behind space

  $1 + 2 = \inframed[frame=off,background=color,backgroundcolor=green,offset=0pt,]{3~\text{kN}}$ % OK!
\stoptext
----

In the sample 'kN' is a unit, which should be separated by space from the result (here: 3);
I am used to put the unit into the math environment and enclose it into \text{...}.

Is there a way to make the bar be rendered in places of blanks within math, too (like if it was inside $ ... $ - as the first line of the sample)?

- Note that I can use \inframed to get background filled fully, but anyway - how about usage of "bar" for this?

Best regards,

Lukas

Use a textbackground to highlight parts of your text.

\definetextbackground
   [Highlight]
   [frame=off,
    background=color,
    backgroundcolor=yellow]

\starttext

\m{1 + 2 = \unit{3 kilo newton}}

\m{1 + 2 = \Highlight{\unit{3 kilo newton}}}

\stoptext

Is there a way to highlight just the words and leave the space white?
Something like \overstrikes?

Wolfgang or whoelse,
when would you advise to use textbackgrounds and when bars? E.g. if I need a “marker” highlighting.
