Elixir wrappers for the Erlang macros in the `wx` package.

this library doesn’t wrap any of `wx`’s functions, but exposes the macros for
constants like `?wxAll` as normal elixir functions (it’s not possible to call
Erlang macros from Elixir code).

## Installation

Add `wx_ex` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:wx_ex, "~> 0.1.0", runtime: false}
  ]
end
```

## Usage

### Constants

```elixir
import Bitwise # to allow ORing of flags with |||
import WxEx.Constants

panel = :wxPanel.new(frame)
label = :wxStaticText.new(panel, wxID_ANY(), "A label", style: wxALIGN_RIGHT())
sizer = :wxBoxSizer.new(wxHORIZONTAL())
:wxSizer.add(sizer, label, flag: wxALL() ||| wxALIGN_CENTRE(), border: 5)

# etc
```

### Records

```elixir
import WxEx.Records

event = wx() #=> {:wx, :undefined, :undefined, :undefined, :undefined}
wx(event) #=> [id: :undefined, obj: :undefined, userData: :undefined, event: :undefined]
```

### Importing everything

To import all constants and records in one line:

```elixir
use WxEx
```

## Development

This library depends on `wx_ex_compiler`, which generates source files and was
extracted to avoid circular compiler dependencies.
