Henri Biestro commented on JEXL-399:
------------------------------------
JEXL is not JavaScript and does not try to be as feature-rich. You will have to
teach chatgpt some of its syntax. Alternatively, have you tried using/embedding
an actual JavaScript interpreter ? (https://github.com/openjdk/nashorn-)
That being said:
6. Fat-arrow for lambda is configurable through JexlFeatures.
1. and 2. could be added as strictEqual/notStrictEqual operators.
3. exponentiation is accessible through Math.pow in Java (true for Javascript
too).
4. destructuring assignment is a very rich feature and complex endeavor.
5. map literals using identifiers as keys without interpretation could be
achieved through options.
7. and 8. can be expressed as for(let k : m.keySet()) and for(let v :
m.valueSet()) when m is a map.
So 6. is here, 1.2 are easy and may be part of next minor version.
The following are unlikely to be implemented in the short term:
5. is a tad more involved in its simplest form (maps) for little gain.
3., 7., 8. are of a low value for JEXL users.
4. is a lot of work for a condensed syntax.

> Project: Commons JEXL
> Issue Type: New Feature
> Reporter: Xu Pengcheng
> Priority: Major
>
> Hi, I am trying ask chatgpt to generate code for some cases, JEXL, as a
> lightweight, secure, easy to communicate with host solution, I think is the
> best option for java world as a bridge between chatgpt and app.
> Unfortunately, chatgpt seems is not familiar with Jexl syntax, so I tried to
> ask chatgpt to write as javascript, I had implements most of the javascript
> build-in objects (like Array, Object, Math, console, etc) for JEXL, 95% cases
> generated by chatgpt can run successfully.
> However, some syntax error will cause the 5% failure, for example:
> # a === b
> # a !== b
> # a = b ** 2
> # const \{a, b} = x;
> # a = \{x: 1, y: 2,}
> # func = () => (\{"a":1, "b": 2})
> # for (let k in map)
> # for (let value of map)
> These syntax looks very reasonable, It will be great to support these
> javascript syntax to let both chatgpt and developer easy to use.
> Thanks!
