Functions

All commands are built on functions that are called in order. Utterly Voice provides many built-in functions that you can use in your commands. This page describes how to use functions, and it describes each of the available functions.

Fixed and Utterance Arguments

Most functions require arguments. These arguments can be supplied as fixed arguments or as utterance arguments.

Fixed arguments are supplied to a function via the command settings. Every time a command is called, these fixed arguments are supplied to the function as defined in the command settings.

Utterance arguments are supplied to a function via words from an utterance.

A function can be supplied no arguments, just fixed arguments, just utterance arguments, or both fixed and utterance arguments. If both types of arguments are supplied, the fixed arguments come before the utterance arguments.

Function Settings

Each mode file contains a list of commands in the commands list collection. Each command has a map collection that contains a functions setting that is a list collection. The functions in this list are called in order when the command is executed. A function has the following settings:

Setting	Type	Description
`name`	String	The name of the function to call.
`fixedArguments`	List Collection	Optional list of fixed arguments for the function. This is a list of strings. If not provided, no fixed arguments are supplied to the function.
`utteranceArguments`	Number	Optional number of arguments that should be acquired from the utterance. If this number is greater than the number of words left in the utterance, the available words will be provided to the function. If you want the remainder of the utterance words to be supplied as function arguments, set this to 100. If not provided, no utterance arguments are supplied to the function.

Examples

The quit utterly voice command in the global mode calls the quit function with no arguments:

  - name: "quit utterly voice"
    description: >-
      Quits the utterly voice application.
    biasFactor: 1.2
    functions:
      - name: "quit"

The type escape command in the basic mode calls the keyPress function with one fixed argument:

  - name: "type escape"
    description: >-
      Presses the escape key.
    alternates:
      - "pipe escape"
    biasFactor: 1.2
    functions:
      - name: "keyPress"
        fixedArguments:
          - "escape"

The title command in the basic mode calls the title function with 100 utterance arguments (the remainder of utterance words):

  - name: "title"
    description: >-
      Use this command to type words in Title Case.
      By default, the remainder of the utterance words are supplied as arguments,
      but you can say "stop" to complete the command
      and continue speaking without pause.
    biasFactor: 1.2
    functions:
      - name: "title"
        utteranceArguments: 100
    spaceLeft: true
    spaceRight: true

The scroll up command in the basic mode calls the mouseScroll function with one fixed argument and one utterance argument:

  - name: "scroll up"
    description: >-
      Scrolls the mouse up.
      The single utterance argument is the number of scroll ticks.
    biasFactor: 1.2
    functions:
      - name: "mouseScroll"
        fixedArguments:
          - "up"
        utteranceArguments: 1

The mouse position command in the basic mode calls the toggleMode function with two fixed arguments, then calls the openMouseGuide function with one fixed argument:

  - name: "mouse position"
    description: >-
      Activates the "mouse pixels" exclusive mode to control the mouse.
    biasFactor: 1.2
    functions:
      - name: "toggleMode"
        fixedArguments:
          - "on"
          - "mouse pixels"
      - name: "openMouseGuide"
        fixedArguments:
          - "pixels"

camel	Types arguments in camelCase. If "stop" is provided as an argument, the function completes.	One or more words to type in camelCase.
closeMouseGuide	Closes the mouse guide. If a mouse action was supplied when opening the guide, the mouse action occurs after the guide closes. Also see openMouseGuide and updateMouseGuide.	The only argument is optional and describes a particular mouse action that should occur when the guide window closes. This will override a mouse action provided to openMouseGuide. The value is one of "left" (left click), "double" (double click), "middle" (middle click), "right" (right click), "start" (start drag), "finish" (finish drag), or "cancel" (perform no mouse action).
ignore	Ignores the provided arguments. This is useful for some exclusive modes, where the `_default` command should ignore utterances. For example, this is used by the "pause" mode.	One or more words to ignore.
kebab	Types arguments in kebab-case.	One or more arguments to type in kabob-case. If the first argument is "upper", use all uppercase. If "stop" is provided as an argument, the function completes.
