Get started

Installation

Install gem:

bundle add opendal

or add it in Gemfile:

# Gemfile

source "https://rubygems.org"

gem 'opendal'

Examples

File operations with an in-memory storage

require 'opendal'

op = OpenDal::Operator.new("memory", {})
op.write("file", "hello world")
puts op.read("file") # => "hello world"
puts ""

puts "List:", op.list("").map { |e| e.path }
puts ""

puts "Stat"
puts op.stat("file").inspect # => #<OpenDal::Metadata mode: File,         content_type: ,         content_length: 11>
puts ""

puts "Deleting 'file'"
op.delete("/file")
puts ""

puts "Exist?", op.exist?("/file") # => false
puts ""

puts "Info:", op.info.inspect # => #<OpenDal::OperatorInfo scheme: "memory", root: "/">

A S3 operator

require 'opendal'

op = OpenDal::Operator.new("s3", {
  "endpoint" => "http://localhost:9000",
  "access_key_id" => "minioadmin" ,
  "secret_access_key" => "minioadmin",
  "bucket" => "test",
  "region" => "us-east-1",
})
op.write("file", "hello world")
puts op.read("file") # => "hello world"
puts ""

puts "List:", op.list("").map { |e| e.path }
puts ""

puts "Stat"
puts op.stat("file").inspect # => #<OpenDal::Metadata mode: File,         content_type: binary/octet-stream,         content_length: 11>
puts ""

puts "Deleting 'file'"
op.delete("file")
puts ""

puts "Exist?", op.exist?("file") # => false
puts ""

puts "Info:", op.info.inspect # => #<OpenDal::OperatorInfo scheme: "s3", root: "/">

Use middleware

require 'opendal'

op = OpenDal::Operator.new("s3", {
  "endpoint" => "http://localhost:9000",
  "access_key_id" => "minioadmin" ,
  "secret_access_key" => "minioadmin",
  "bucket" => "test",
  "region" => "us-east-1",
})

op.middleware(OpenDal::Middleware::ConcurrentLimit.new(5))
op.middleware(OpenDal::Middleware::Retry.new)
op.middleware(OpenDal::Middleware::Timeout.new(1, 2))

op.list("/").map do |e|
  puts e.inspect
end
