Place the following in a tiddler (e.g., "ShowLinesMacro"), tagged with
$:/tags/Macro"
\define showLines(tid,from,to)
<$vars length={{{ [[$to$]subtract[$from$]add[1]] }}}>
<$set name="lines"
filter="[[$tid$]get[text]splitregexp[\n]first[$to$]last<length>]">
<pre><$list filter="[enlist:raw<lines>]" variable="line"><$text
text=<<line>>/><br></$list></pre>
</$set>
</$vars>
\end
which can then be invoked using:
<<showLines "Slab Catalyst" 3 5>>
<hr>
<<showLines "Slab Catalyst" 8 19>>
enjoy,
