# Galapagos

Evolutionary language transformation. Fork of [igorw](https://github.com/igorw)'s initial work.

Read the related [blog post](https://igor.io/2013/07/26/evolving-syntax.html).

Backport existing PHP features to previous versions through AST compilation.

Inspired by lisp macros. Using the incredible

[nikic/PHP-Parser](https://github.com/nikic/PHP-Parser).

## Missing features

### 5.4

* Binary number format

* Closure rebinding

Edge cases:

* Calling private methods from within closure

* Ensure `$that` gets passed to nested closures

### State

There needs to be a strategy for managing state. A trait transformer needs to

keep track of the traits it found. That is currently missing.

### Preservation

There should be a way to preserve existing code formatting, especially for

code that wasn't actually modified. Instead of pretty-printing everything,

only changed parts of the AST should be changed in source. Three-way-diff may

help with this.

### Line numbers

Is there any way to do something like source maps to refer to the original

line numbers, so that code remains at all debuggable?
