README

BSON

BSON implemented in Crystal according to the spec.

Installation

Add this line to your application's shard.yml:

dependencies:
  bson:
    github: jeromegn/bson.cr

Usage

require "bson"

io = File.open(File.expand_path("examples/sample.bson")) # A pretty representative BSON document
BSON.decode(io) # => Returns a Hash instance

bson, writer = IO.pipe
"a string".to_bson(writer) # => encodes the string to BSON and writes to the IO

puts String.from_bson(bson).inspect # => "a string"

doc = Hash{
  "name" => "hello",
  "int" => 32
}

puts doc # => { "name" => "hello", "int" => 32 }

bson, writer = IO.pipe
doc.to_bson(writer) # => Encodes the whole document to BSON and writes to the IO

puts BSON.decode(bson) # => { "name" => "hello", "int" => 32 }

Supported types

All types specified in the BSON spec.

Relevant basic types of Crystal have been extended to add #to_bson(io : IO) and .from_bson(io : IO) for simplicity.

A BSON::Document is just an alias for Hash(String, BSON::Type)

TODOs

  • [ ] More tests

Caveats

  • Only supported Regex options are the ones also supported by Crystal: i and m basically.
