Hi Bob and others,
currently it can be difficult to get/set elements within a multi-level
nested array/hash data structure in Jmol depending on the context.
Example data structure:
x = {"a": {"1": ["x", "y", "z"], "2": ["I", "II"]}}
And there is also the ambiguity of an expression like 'x[1][3]' which
might mean element '1' to '3' or even character '1' to '3' instead of
element '3' of element '1' of array 'x'.
Q: What would you think about implementing the Perl "arrow" syntax
(using "->", see example below) as an alternative syntax for accessing
nested data structures?
Example Perl syntax for accessing the element with value "II" from the
example above:
x["a"]->[2]->[2]
In Perl I frequently use data structures with five or more levels, for
example as output from an XML parser. There this syntax helps to make
the code much better readable. And it sometimes also assists the Perl
parser to interpret code as intended.
As far as I know, "->" is not used yet within Jmol. So it shouldn't
collide with any existing syntax.
Regards,
Rolf
