Allow usage of "select" scripting command with a string as first parameter.
Should return a string containing the selected character.
e.g.
"foobar" select 3
returns:
"b"
functionality should be available in the engine because
String select SCALAR
is just a shortcut for:
toString [toArray STRING select SCALAR]
there are some more scripting commands for arrays which could be useful for strings, too - count, set, ...
IMO substring command would do what you want and more. Ive privately asked for it already, but no guarantees of course.
getting a substring command was the plan - was preparing a feature ticket for "b:ARRAY select ARRAY"
with a syntax similar to the extended slicing syntax of python
but I think extending the select command for usage with strings would be quite handy anyway - and the same syntax is available in o2script
This is what I had in mind. I pretty sure there has to be substring method in A3
strSubstr
STRING = STRING strSubstr ARRAY;
ARRAY - [start, stop]
Extracts the characters in a string between 'start' and 'stop', not including 'stop' itself.
"Hello" strSubstr [1,4]; ell
When only one param specified, substring is extracted from 'start' to end.
"Hello" strSubstr [2]; //llo
