hs.pasteboard

An array whose elements are a table containing the content types for each element on the clipboard.

• name - an optional string indicating the pasteboard name. If nil or not present, defaults to the system pasteboard.

• an array with each index representing an object on the pasteboard. If the pasteboard contains only one element, this is equivalent to { hs.pasteboard.contentTypes(name) }.

Invokes callback when the specified pasteboard has changed or the timeout is reached.

• name - an optional string indicating the pasteboard name. If nil or not present, defaults to the system pasteboard.
• timeout - an optional number, default 2.0, specifying the time in seconds that this function should wait for a change to the specified pasteboard before timing out.
• callback - a required callback function that will be invoked when either the specified pasteboard contents have changed or the timeout has been reached. The function should expect one boolean argument, true if the pasteboard contents have changed or false if timeout has been reached.

• None

• This function can be used to capture the results of a copy operation issued programmatically with hs.application:selectMenuItem or hs.eventtap.keyStroke without resorting to creating your own timers:

    hs.eventtap.keyStroke({"cmd"}, "c", 0) -- or whatever method you want to trigger the copy
    hs.pasteboard.callbackWhenChanged(5, function(state)
        if state then
            local contents = hs.pasteboard.getContents()
            -- do what you want with contents
        else
            error("copy timeout") -- or whatever fallback you want when it times out
        end
    end)

Gets the number of times the pasteboard owner has changed

• name - An optional string containing the name of the pasteboard. Defaults to the system pasteboard

• A number containing a count of the times the pasteboard owner has changed

• This is useful for seeing if the pasteboard has been updated by another process

• None

Return the UTI strings of the data types for the first pasteboard item on the specified pasteboard.

• name - An optional string containing the name of the pasteboard. Defaults to the system pasteboard

• a table containing the UTI strings of the data types for the first pasteboard item.

Deletes a custom pasteboard

• name - A string containing the name of the pasteboard

• None

• You can not delete the system pasteboard, this function should only be called on custom pasteboards you have created

Gets the contents of the pasteboard

• name - An optional string containing the name of the pasteboard. Defaults to the system pasteboard

• A string containing the contents of the pasteboard, or nil if an error occurred

Return the pasteboard type identifier strings for the specified pasteboard.

• name - An optional string containing the name of the pasteboard. Defaults to the system pasteboard

• a table containing the pasteboard type identifier strings

Returns all values in the first item on the pasteboard in a table that maps a UTI value to the raw data of the item

• name - an optional string indicating the pasteboard name. If nil or not present, defaults to the system pasteboard.

a mapping from a UTI value to the raw data

Returns the first item on the pasteboard with the specified UTI. The data on the pasteboard must be encoded as a keyed archive object conforming to NSKeyedArchiver.

• name - an optional string indicating the pasteboard name. If nil or not present, defaults to the system pasteboard.
• uti - a string specifying the UTI of the pasteboard item to retrieve.

• a lua item representing the archived data if it can be decoded. Generates an error if the data is in the wrong format.

• NSKeyedArchiver specifies an architecture-independent format that is often used in OS X applications to store and transmit objects between applications and when storing data to a file. It works by recording information about the object types and key-value pairs which make up the objects being stored.
• Only objects which have conversion functions built into Hammerspoon can be converted. A string representation describing unrecognized types wil be returned. If you find a common data type that you believe may be of interest to Hammerspoon users, feel free to contribute a conversion function or make a request in the Hammerspoon Google group or GitHub site.
• Some applications may define their own classes which can be archived. Hammerspoon will be unable to recognize these types if the application does not make the object type available in one of its frameworks. You may be able to load the necessary framework with package.loadlib("/Applications/appname.app/Contents/Frameworks/frameworkname.framework/frameworkname", "*") before retrieving the data, but a full representation of the data in Hammerspoon is probably not possible without support from the Application's developers.

  • a lua string, which can be received by most applications that can accept text from the clipboard
  • hs.styledtext object, which can be received by most applications that can accept a raw NSAttributedString (often converted internally to RTF, RTFD, HTML, etc.)
  • hs.sound object, which can be received by most applications that can accept a raw NSSound object
  • hs.image object, which can be received by most applications that can accept a raw NSImage object
  • a table with the url key and value representing a file or resource url, which can be received by most applications that can accept an NSURL object to represent a file or a remote resource
