Perhaps - certainly 'textFont' and 'textSize' have less syntactic
baggage. However, the actual underlying form/pattern/functionality is
identical:
the <prop> of the selectedChunk
Returns "mixed" if <prop> is not the same across all chars, otherwise
the value of <prop> (or empty if unset across all of them - i.e.
inherited).
You could introduce the text style ones as 'prepackaged' units though:
the textStyle["bold"] of the selectedChunk
the textStyle["italic"] of the selectedChunk
This isn't really a 'lie' either - as these aren't really array
properties in the same way as when you use that syntactic form as a
custom property. In an ideal world they would have been done as 'the
bold of' etc. We didn't do that for the simple reason that the number of
times I have seen 'bold', 'italic' and other textStyle keywords as
variable names and custom property names might be most surprising - i.e.
had we, an unknown number of stacks would have broken, quite severely!
[Although with hindsight perhaps we should have considered textBold /
textItalic ... ].
Warmest Regards,
Mark.
P.S. Of course, at least one 'smart-ass' will ask 'why do those have
brackety things when the others don't' - but aren't teachers well versed
in dealing with such inquisitive minds? ;)
