# eslisp-propertify [![](https://img.shields.io/npm/v/eslisp-propertify.svg?style=flat-square)][1] [![](https://img.shields.io/travis/anko/eslisp-propertify.svg?style=flat-square)][2] [![](https://img.shields.io/badge/eslisp_chat-gitter_%E2%86%92-blue.svg?style=flat-square)][3]

An [eslisp][4] macro that rewrites its input forms' atoms that contain dots

into property accesses.  This means you can write `x.y.1` instead of `(. x y

1)`, which compiles to JS as `x.y[1];`.

Ignores trailing and leading dots, and atoms that consist of dots.

## Example

    (macro propertify (require "/path/to/elisp-propertify/index.js"))

    (propertify (a.b 42))

↓

    a.b(42);

See [the tests][5] for fuller usage.

## Full wrap

It's totally reasonable to wrap your whole program in this.  Consider the

eslisp compiler's `--transform` flag.

## Limitations

If you need a computed member expression, you'll still need the `.` macro: For

example, to get `a.b[b.length]`, you'll need to write `(.  a.b b.length)`.
