-------------------------------------------
Summary: Deprecate -> and support =>
Key: JEXL-367
URL: https://issues.apache.org/jira/browse/JEXL-367
Project: Commons JEXL
Issue Type: Wish
Reporter: Hussachai Puripunpinyo
The JEXL code surprisingly looks a lot like Javascript. I think this change is
a good transition for folks to update the code, and it's pretty fine if they
can tolerate using the deprecate syntax and don't mind seeing a warning log pop
up every time.
I'd like to propose supporting => and deprecate ->.
The reasons are
- JavaScript becomes very popular and many people are familiar with it.
- JEXL is more like for a quick short script. In many scenarios, the target
audiences are not a programer. They often mistake a language as a JavaScript
(from my experience).
- JEXL syntax already looks a lot like JavaScript
- var for variable declaration (Java added in Java 10, but JavaScript
supports this from the beginning)
- The function keyword
- Implicit type coercion
- Ternary operator
The proposed change.
* Support => in addition to ->
* Deprecate -> and show a warning log when it's used.
