DisplayExpression

Added in v4.1.0, DisplayExpression allows the use to customise the way a note's name is displayed within Tinderbox.

Some users find it helpful to use actions and rules to append information to not names, e.g. a word count, number of children or the value of some attribute. However, this does change the actual name of the note and can cause problems with other actions which don't expect note names to change.

DisplayExpression helps overcome this by working in conjunction with another new (read-only) attribute, DisplayName. The latter (q.v.) display's the Name of a note after the action in DisplayExpression is applied. The existing Name value is unaffected allowing other notes to make explicit reference to a given note.

For each note, Tinderbox evaluates that note's DisplayExpression to create the note's name, as displayed. However, if DisplayExpression is empty - or not a valid action syntax expression - then the note's Name value is used instead.

Example rule:

$Name +" (" + $WordCount + ")"

...will display the note's word count in brackets at the end of the note. Thus, "Trip Report" becomes "Trip Report (579)". $Name will continue to return "Trip Report".

This attribute is of the 'action' data type. It takes a string argument which must be valid action syntax.
