str2hash

Tiny parser for converting strings to hashes (without using eval).

Usage

str2hash adds String#to_h

require 'str2hash'

"{ :foo => 123 }".to_h => {:foo=>123}
"{ :foo => -123 }".to_h => {:foo=>-123}
"{ :foo => :bar }".to_h => {:foo=>:bar}
"{ :foo => 123.456 }".to_h => {:foo=>123.456}
"{ :foo => -123.456 }".to_h => {:foo=>-123.456}
"{ :foo => 0x0123 }".to_h => {:foo=>291}
"{ :foo => -0x0123 }".to_h => {:foo=>-291}
"{ :foo => 0b010010010100010101}".to_h => {:foo=>75029}
"{ :foo => -0b010010010100010101}".to_h => {:foo=>-75029}
"{ 123 => 456 }".to_h => {123=>456}
"{ foo: 456 }".to_h => {:foo=>456}
"{ foo: :bar }".to_h => {:foo=>:bar}
"{ foo: '123' }".to_h => {:foo=>"123"}
"{ foo: "123" }".to_h => {:foo=>"123"}
"{ foo: /foo/ }".to_h => {:foo=>/foo/}
"{ foo: true }".to_h => {:foo=>true}
"{ :foo => :bar, :foo2 => :bar2}".to_h => {:foo=>:bar, :foo2=>:bar2}
":foo => :bar, :foo2 => :bar2".to_h => {:foo=>:bar, :foo2=>:bar2}

Limitations

No nested hashes, no arrays (yet). No bindings, only values.
