to_lua

Serialize Ruby objects to lua tables

Installation

Add this line to your application's Gemfile:

gem 'to_lua'

And then execute:

$ bundle

Or install it manually with:

$ gem install to_lua

Usage

{a: 'hash'}.to_lua       # {a="hash"}
[:some, :array].to_lua   # {"some","array"}
"\nStr\"ing\x00".to_lua  # "\nStr\"ing\0"
123456.to_lua            # 123456
3.14159.to_lua           # 3.14159
true.to_lua              # true
false.to_lua             # false
nil.to_lua               # nil

Options

Pretty formatting

{a: 'hash', with: {a_nested: 'hash'}}.to_lua(pretty: true)

# {
#   a = "hash",
#   with = {
#     a_nested = "hash"
#   }
# }

Custom indentation

{a: 'hash', with: {a_nested: 'hash'}}.to_lua(pretty: true, indent: '')

# {
# a = "hash",
# with = {
# a_nested = "hash"
# }
# }

Custom objects

Custom objects can define the as_lua method. The return value will be serialized with to_lua. Example:

class CustomObject
  def as_lua
    { lua: 'object' }
  end
end

CustomObject.new.to_lua  # {lua="object"}

If an object does not define the as_lua method, to_s will be used instead and the object will be serialized as a string.
