# PyJEXL

A Python-based JEXL parser and evaluator.

__NOTE:__ This library handles the "Java__Script__ Expression Language" from
[TechnologyAdvice's JEXL library][jexl]. It does __NOT__ handle the
similarly-named Apache Commons JEXL language.

## Limitations and Differences from JEXL

- JavaScript-style implicit type conversions aren't supported, but may be added
in the future. Instead, Python type semantics are used.
- Property access is only supported for mapping objects currently.
- Several odd edge-cases in JEXL are ignored because they are unintuitive,
difficult to implement, or a bad pattern:
- Implicitly using the first element in an array when chaining identifiers
is not supported. In JEXL, if `foo.bar` is a list, the expression
`foo.bar.baz` is equivalent to `foo.bar[0].baz`.
- Conditional expressions (AKA ternary expressions) cannot have a missing
consequent, i.e. `"foo" ?: 4` is invalid.
