Alfredo: A Node.js Module for Alfred Workflows

Alfredo's primary features include:

  • Functions for finding your bundle ID, cache and storage paths, and query arguments.
  • Functions for reading and writing JSON and plist files.
  • A function to perform fuzzy searching operations.
  • A class to simplify generating feedback XML for Alfred.

Installation

npm install alfredo

Core Functions

These are intended to make some basic rote tasks easier and faster to code. alfredo defines the following functions:

  • alfredo.bundleSync()
    This function returns the bundle ID for your workflow by reading it from its Info.plist file.
  • alfredo.readPlistSync(path), alfredo.writePlistSync(path, obj), alfredo.readJSONSync(path), alfredo.writeJSONSync(path, obj)
    These functions will read from and write to the plist or JSON files located at path.

Feedback System

Alfredo uses a robust and complete implementation of Alfred's feedback system, generating and outputting the required XML for the attributes you specify. This breaks down into a class called Item and a function called feedback.

  • alfredo.Item(args)
    The Item class is initialized with an object of keys and values, and returns one Item which can then be passed to the feedback function. The following keys are currently understood by Alfredo and Alfred:

    • title: The title string to show in the feedback list.
    • subtitle: The subtitle string to show below the title.
    • uid: A unique identifier string for Alfred's sorting functions.
    • valid: Either true, false, or a string. Tells Alfred whether the item is actionable.
    • autocomplete: A string to autocomplete Alfred's query to when an invalid item is chosen.
    • icon: A path to an icon image, a path to a file, or a file type (default: icon.png).
    • fileIcon: If you wish to use a particular file's icon, set icon to its path and fileIcon to true.
    • fileType: If you wish to specify a type of file whose icon Alfred should use, set icon to the type and fileType to True.
    • arg: The argument to be passed as {query} if the item is valid and actioned. If it contains newlines, it will be passed as a separate XML key rather than an attribute of <item></item>.
    • type: Currently, can only be set to file, which tells Alfred to treat the result as a file.

    A nifty trick is to pass an object with some or all of Alfredo.Item's keys and values into the initializer. So you could conceivably do this:

    var i = alfredo.Item({
      title: "A Title", 
      subtitle: "This is only a test.", 
      uid: "alfredo-test", 
      valid: false
    })
    
  • Item.get()
    Returns the current values for the item in the following format. Primarily used with the feedback() function below.

    If autocomplete or type is set, that value will be added to the "attrib" dictionary, as will an arg that does not contain newlines.

  • Item.feedback(), alfredo.feedback(items)
    Takes either an individual item or a list of items for items and prints a UTF-8-encoded XML string for Alfred to interpret.

Fuzzy Search

Alfredo's fuzzy search is powered by the fuzzy-filter node module by DJG.

alfredo.fuzzy(pattern, items, [options])

Parameters

pattern - The fuzzy String to match against.
items   - An Array of String.
options - (optional)
        * pre         - String to insert before matching text.
        * post        - String to insert after matching text.
        * limit       - Integer maximum number of results.
        * separator   - String separator. Match against the last
                        section of the String by default.
        * ignorecase  - Boolean (default: true).
        * ignorespace - Boolean (default: true).
        * separate    - Boolean (default: false). If set to true, the
                        function returns an array of an array of strings,
                        where each array is
                        [beforeLastSeparator, afterLastSeparator].
                        If set, `separator` must also be passed.

Note: If pre is passed, you also have to pass post (and vice-versa).

Example

alfredo.fuzzy("cs", ["cheese", "pickles", "crackers", "pirate attack", "cs!!"])
// => ["cs!!", "cheese", "crackers"]

Keychain Interface

If your workflow needs to store a user's sensitive data, particularly a username--password pair, the safest way to do so is with the Mac OS X Keychain. The Keychain is normally an utter pain in the behind, but Alfredo makes working with it a breeze using the node-keychain module.

  • alfredo.keychain.getPasswordSync(opts)
    Searches the Keychain for an account matching the passed opts.account and opts.service, returning the password.
  • alfreo.keychain.setPasswordSync(opts) Saves or changes the saved password for opts.account and opts.service to opts.Password.
  • alfredo.keychain.deletePasswordSync(opts) Removes opts.account and opts.service's password from the Keychain.
