Usage

Include to project and login

# require directly
require 'yandex_disk'

# or in Gemfile
gem 'yandex_disk'

# login
yd = YandexDisk.login(login, pwd)

Upload file

yd.upload(file, path, options)

return true if success else raise RequestError

options:

• :chunk_size file chunk size, default is 1024

• :force create path if not exist, default raise error

example:

# create "my/work" directory and upload file to "/my/work/graph.pdf" using chunk size 500 per request
yd.upload('/home/graph.pdf', 'my/work', { :force => true, :chunk_size => 500 })

Download file

yd.download(file, save_path)

if save_path not present - return file content else return true when save file

example:

# download file to "/home/graph.pdf"
yd.download('/my/work/graph.pdf', '/home') #=> true

# keep file content in memory
yd.download('/my/work/graph.pdf') #=> String

Create path

yd.create_path(path)

return true if success else raise RequestError

alias: mkdir

example:

# create "/my/work" path
yd.mkdir('/my/work')

Get available and used space

yd.size(options)

options:

• :h_size return size in human readable format (for default return in bytes) 15 Byte, 100 KB, etc

example:

yd.size # => { :available => 213133, :used => 321 }
yd.size(:h_size => true) #=> { :available =>  '7.8 GB', :used => '200 MB' }

File exist?

yd.exist?(file) 

return true if file exist else false

example:

yd.exist?('/home/graph.pdf') #=> true

Get file properties

yd.properties(file, options)

return Hash { :name, :created, :updated, :type, :size, :is_file, :public_url } if success else raise RequestError

options:

• :h_size return size in human readable format (for default return in bytes) 15 Byte, 100 KB, etc

example:

prop = yd.properties('/home/graph.pdf', { :h_size => true })
prop[:is_file] #=> true
prop[:size] #=> 25 MB

Return list of files properties in directory

yd.files(path, options)

return Array with Hash [{ :name, :created, :updated, :type, :size, :is_file }] if success else raise RequestError

options:

• :h_size return size in human readable format (for default return in bytes) 15 Byte, 100 KB, etc

• :root include properties for root directory ("home" in example)

alias: ls

example:

files = yd.files('/home')
files[0][:name] #=> graph.pdf

# with root
files = yd.properties('/home', { :root => true })
files[0][:name] #=> 'home'

Copy file or directory

yd.copy(from, to)

return true if successful else raise RequestError

alias: cp

example:

yd.copy('/home/graph.pdf', '/backup') # copy "graph.pdf" to "backup" directory

Move file or directory

yd.move(from, to)

return true if successful else raise RequestError

alias: mv

example:

yd.move('/home/graph.pdf', '/pdfs') # move "graph.pdf" to "pdfs" directory

Delete file or directory

yd.delete(path)

return true if successful else raise RequestError

alias: del

example:

yd.delete('/home/graph.pdf') # delete "graph.pdf"

Set public access for file or directory

yd.set_public(path)

return public url if successful else raise RequestError

example:

yd.set_public('/home/graph.pdf') #=> http://yadi.sk/d/#############

Set private file or directory

yd.set_private(path)

return true if successful else false

example:

yd.set_private('/home/graph.pdf') #=> true

Get image preview

preview(path, size, save_to)

save image if successful else raise RequestError size supported value:

T-shirt size (like in Yandex.Fotki), such as size=M. Yandex.Disk returns a preview in the size you selected:
XXXS — 50 pixels on each side (square).
XXS  — 75 pixels on each side (square).
XS   — 100 pixels on each side (square).
S    — 150 pixels wide, preserves original aspect ratio.
M    — 300 pixels wide, preserves original aspect ratio.
L    — 500 pixels wide, preserves original aspect ratio.
XL   — 800 pixels wide, preserves original aspect ratio.
XXL  — 1024 pixels wide, preserves original aspect ratio.
XXXL — 1280 pixels wide, preserves original aspect ratio.

A number, such as size=128.
Yandex.Disk returns a preview with this width. If the specified width is more than 100 pixels, the preview preserves the aspect ratio of the original image.
Otherwise, the preview is additionally modified: the largest possible square section is taken from the center of the image to scale to the specified width.

Exact dimensions, such as size=128x256.
Yandex.Disk returns a preview with the specified dimensions. The largest possible section with the specified width/height ratio is taken from the center of the original image (in the example, the ratio is 128/256 or 1/2). Then this section of the image is scaled to the specified dimensions. See the example with exact dimensions below.

Exact width or height, such as size=128x or size=x256.
Yandex.Disk returns a preview with the specified width or height that preserves the aspect ratio of the original image.

View the original api page for details.

example:

yd.preview('/photo/car.jpg', 'm', '/home') # save "car.jpg" with 300 pixels wide to home directory
yd.preview('/photo/car.jpg', 128, '/home') # save preview 128 pixels wide to home directory
