Encoding html entities

By default html entities "<",">" and "&" are escaped. To disable this behaviour you can set a property 'envelope.escape' to false. Bear in mind that Skype doesn't allow some html tags and silently ignores messages with unclosed tags.

  robot.respond /small/i, (res) ->
    html = "<font size=\"15\">It's small</font>"
    res.send html

  robot.respond /big/i, (res) ->
    res.envelope.escape = false
    html = "<font size=\"15\">It's big</font>"
    res.send html

Send files

Attachments can be send using Skype Bot Api. Supported types 'Images', 'Videos' and 'Files'. To send attachment you need to emit a 'skype:sendAttachment' event with params:

• user - a User object
• attachmentName - File/Image/Video name
• attachmentType - a type of a data content (File, Image or Video)
• originalStream - a nodejs stream of the data content
• thumbnailStream - (optional) nodejs stream of a video thumbnail content. Used only by Video type. Videos thumbnails should be JPEG

Send File

robot.respond /get settings/i, (res) ->
    user = res.envelope.user
    originalStream = fs.createReadStream("files/settings.json")
    robot.emit 'skype:sendAttachment', user, 'settings.json', 'FILE',  originalStream

Send Image

robot.respond /get image with funny cats/i, (res) ->
    user = res.envelope.user
    originalStream = fs.createReadStream("files/funny_cats.jpg")
    robot.emit 'skype:sendAttachment', user, 'funny_cats.jpg', 'Image',  originalStream

Send Video

robot.respond /get epic fail video/i, (res) ->
    user = res.envelope.user
    originalStream = fs.createReadStream("files/epic_fail.mp4")
    thumbnailStream = fs.createReadStream("files/thumbnail-epic_fail.jpg")
    robot.emit 'skype:sendAttachment', user, 'epic_fail.mp4', 'Video',  originalStream, thumbnailStream

Receive File

Attachments can be received using Skype Bot Api. When SkypeBots adapter receive a new attachment it emit a 'skype:attachment' with params

• user - a User object
• attachmentName - File/Image/Video name
• attachmentType - a type of a data content (File, Image or Video)
• attachmentStream - a nodejs stream of a data content

robot.on 'skype:attachment', (user, attachmentName, attachmentType, attachmentStream) ->
    robot.logger.info "Revceived attachment #{attachmentName} of type #{attachmentType} from #{user.id} in room #{user.room}"
    attachmentStream.pipe(fs.createWriteStream("files/#{attachmentName}"))
