----------------------------------
Summary: Introduce short-handed ternary operation x ? y
Key: JEXL-276
URL: https://issues.apache.org/jira/browse/JEXL-276
Project: Commons JEXL
Issue Type: Improvement
Affects Versions: 3.1
Reporter: Dmitri Blinov
A short-handed ternary operation {{x ? y}} is an equivalent of the {{x ? y :
null}}. The {{x : y}} operator is analogous to {{if (x) y}} statement with
{{else}} part omitted. With new syntax we will have ternary operator and {{if}}
statement to have full symmetry of forms, e.g.
{{x ? y : x}} is {{if (x) y else z}}, {{x ? y}} is {{if (x) y}}
Just to note, the proposed short-handed differs from Elvis operator {{x ?: y}}
which is effectively {{x ? x : y}}. In other words, elvis operator allows for
the middle part of the ternary operator to be omitted, whereas the proposed
form allows for the imission of the last part.
