[gogo] no way to access array[] elements produced by assignment
---------------------------------------------------------------
Key: FELIX-2337
URL: https://issues.apache.org/jira/browse/FELIX-2337
Project: Felix
Issue Type: Bug
Components: Gogo
Reporter: Derek Baum
Assignee: Derek Baum
Priority: Minor
Fix For: gogo-0.6.0
the following two alternative assignments, should be equivalent:
x = command args ...
x = (command args ..)
but they are not, if the result is an array:
% x = [a b c] toarray
% $x get 0
IllegalArgumentException: Cannot coerce get[0] to any of []
% x = ([a b c] toarray)
% $x get 0
This is because gogo normally converts any array result into a list
(Closure.java:228):
if (last.result instanceof Object[])
{
return Arrays.asList((Object[]) last.result);
}
but the assignment without () bypasses this conversion, and results in a real
array.
I can obviously fix this so that the conversion to a List occurs in all cases,
but I was wondering whether gogo should be performing this conversion in the
first place? If the conversion is not performed, then we'll need to support
($array $index) to access arrays.
