---

Create and manipulate toolbars which can be attached to the Hammerspoon console or hs.webview objects.

Toolbars are attached to titled windows and provide buttons which can be used to perform various actions within the application. Hammerspoon can use this module to add toolbars to the console or hs.webview objects which have a title bar (see hs.webview.windowMasks and hs.webview:windowStyle). Toolbars are identified by a unique identifier which is used by OS X to identify information which can be auto saved in the application's user defaults to reflect changes the user has made to the toolbar button order or active button list (this requires setting hs.webview.toolbar:autosaves and hs.webview.toolbar:canCustomize both to true).

Multiple copies of the same toolbar can be made with the hs.webview.toolbar:copy method so that multiple webview windows use the same toolbar, for example. If the user customizes a copied toolbar, changes to the active buttons or their order will be reflected in all copies of the toolbar.

Example:

t = require("hs.webview.toolbar")
a = t.new("myConsole", {
        { id = "select1", selectable = true, image = hs.image.imageFromName("NSStatusAvailable") },
        { id = "NSToolbarSpaceItem" },
        { id = "select2", selectable = true, image = hs.image.imageFromName("NSStatusUnavailable") },
        { id = "notShown", default = false, image = hs.image.imageFromName("NSBonjour") },
        { id = "NSToolbarFlexibleSpaceItem" },
        { id = "navGroup", label = "Navigation", groupMembers = { "navLeft", "navRight" }},
        { id = "navLeft", image = hs.image.imageFromName("NSGoLeftTemplate"), allowedAlone = false },
        { id = "navRight", image = hs.image.imageFromName("NSGoRightTemplate"), allowedAlone = false },
        { id = "NSToolbarFlexibleSpaceItem" },
        { id = "cust", label = "customize", fn = function(t, w, i) t:customizePanel() end, image = hs.image.imageFromName("NSAdvanced") }
    }):canCustomize(true)
      :autosaves(true)
      :selectedItem("select2")
      :setCallback(function(...)
                        print("a", inspect(table.pack(...)))
                   end)

t.attachToolbar(a)

Notes:

• This module is supported in OS X versions prior to 10.10 (for the Hammerspoon console only), even though its parent hs.webview is not. To load this module directly, use require("hs.webview.toolbar") instead of relying on module auto-loading.
• Toolbar items are rendered in the order they are supplied, although if the toolbar is marked as customizable, the user may have changed the order.

API Documentation

Constants

itemPriorities

Signature	hs.webview.toolbar.itemPriorities
Type	Constant
Description	A table containing some pre-defined toolbar item priority values for use when determining item order in the toolbar.

systemToolbarItems

Signature	hs.webview.toolbar.systemToolbarItems
Type	Constant
Description	An array containing string identifiers for supported system defined toolbar items.

Functions

attachToolbar

Signature	hs.webview.toolbar.attachToolbar([obj1], [obj2]) -> obj1
Type	Function
Description	Get or attach/detach a toolbar to the webview, chooser, or console.
Parameters	obj1 - An optional toolbarObject obj2 - An optional toolbarObject if no arguments are present, this function returns the current toolbarObject for the Hammerspoon console, or nil if one is not attached. if one argument is provided and it is a toolbarObject or nil, this function will attach or detach a toolbarObject to/from the Hammerspoon console. if one argument is provided and it is an hs.webview or hs.chooser object, this function will return the current toolbarObject for the object, or nil if one is not attached. if two arguments are provided and the first is an hs.webview or hs.chooser object and the second is a toolbarObject or nil, this function will attach or detach a toolbarObject to/from the object.
Returns	if the function is used to attach/detach a toolbar, then the first object provided (the target) will be returned ; if this function is used to get the current toolbar object for a webview, chooser, or console, then the toolbarObject or nil will be returned.
Notes	This function is not expected to be used directly (though it can be) -- it is added to the hs.webview and hs.chooser object metatables so that it may be invoked as hs.webview:attachedToolbar([toolbarObject

inTitleBar

| Signature | hs.webview.toolbar:inTitleBar([state]) -> toolbarObject | boolean | | -----------------------------------------------------|---------------------------------------------------------------------------------------------------------| | Type | Function | | Description | Get or set whether or not the toolbar appears in the containing window's titlebar, similar to Safari. | | Parameters |

• state - an optional boolean specifying whether or not the toolbar should appear in the window's titlebar.

| | Returns |

• if a parameter is specified, returns the toolbar object, otherwise the current value.

| | Notes |

• When this value is true, the toolbar, when visible, will appear in the window's title bar similar to the toolbar as seen in applications like Safari. In this state, the toolbar will set the display of the toolbar items to icons without labels, ignoring changes made with hs.webview.toolbar:displayMode.

|

uniqueName

Signature	hs.webview.toolbar.uniqueName(toolbarName) -> boolean
Type	Function
Description	Checks to see is a toolbar name is already in use
Parameters	toolbarName - a string specifying the name of a toolbar
Returns	true if the name is unique otherwise false

Constructors

new

Signature	hs.webview.toolbar.new(toolbarName, [toolbarTable]) -> toolbarObject
Type	Constructor
Description	Creates a new toolbar for a webview, chooser, or the console.
Parameters	toolbarName - a string specifying the name for this toolbar toolbarTable - an optional table describing possible items for the toolbar
Returns	a toolbarObject
Notes	Toolbar names must be unique, but a toolbar may be copied with hs.webview.toolbar:copy if you wish to attach it to multiple windows (webview, chooser, or console). See hs.webview.toolbar:addItems for a description of the format for toolbarTable

Methods

addItems

Signature	hs.webview.toolbar:addItems(toolbarTable) -> toolbarObject
Type	Method
Description	Add one or more toolbar items to the toolbar
Parameters	toolbarTable - a table describing a single toolbar item, or an array of tables, each describing a separate toolbar item, to be added to the toolbar.
Returns	the toolbarObject
Notes	Each toolbar item is defined as a table of key-value pairs. The following list describes the valid keys used when describing a toolbar item for this method, the constructor hs.webview.toolbar.new, and the hs.webview.toolbar:modifyItem method. Note that the id field is required for all three uses. id - A unique string identifier required for each toolbar item and group. This key cannot be changed after an item has been created. allowedAlone - a boolean value, default true, specifying whether or not the toolbar item can be added to the toolbar, programmatically or through the customization panel, (true) or whether it can only be added as a member of a group (false). default - a boolean value, default matching the value of allowedAlone for this item, indicating whether or not this toolbar item or group should be displayed in the toolbar by default, unless overridden by user customization or a saved configuration (when such options are enabled). enable - a boolean value, default true, indicating whether or not the toolbar item is active (and can be clicked on) or inactive and greyed out. This field is ignored when applied to a toolbar group; apply it to the group members instead. fn - a callback function, or false to remove, specific to the toolbar item. This property is ignored if assigned to the button group. This function will override the toolbar callback defined with hs.webview.toolbar:setCallback for this specific item. The function should expect three (four, if the item is a searchfield) arguments and return none. See hs.webview.toolbar:setCallback for information about the callback's arguments. groupMembers - an array (table) of strings specifying the toolbar item ids that are members of this toolbar item group. If set to false, this field is removed and the item is reset back to being a regular toolbar item. Note that you cannot change a currently visible toolbar item to or from being a group; it must first be removed from active toolbar with hs.webview.toolbar:removeItem. image - an hs.image object, or false to remove, specifying the image to use as the toolbar item's icon when icon's are displayed in the toolbar or customization panel. This key is ignored for a toolbar item group, but not for it's individual members. label - a string label, or false to remove, for the toolbar item or group when text is displayed in the toolbar or in the customization panel. For a toolbar item, the default is the id string; for a group, the default is false. If a group has a label assigned to it, the group label will be displayed for the group of items it contains. If a group does not have a label, the individual items which make up the group will each display their individual labels. priority - an integer value used to determine toolbar item order and which items are displayed or put into the overflow menu when the number of items in the toolbar exceed the width of the window in which the toolbar is attached. Some example values are provided in the hs.webview.toolbar.itemPriorities table. If a toolbar item is in a group, it's priority is ignored and the item group is ordered by the item group's priority. searchfield - a boolean (default false) specifying whether or not this toolbar item is a search field. If true, the following additional keys are allowed: searchHistory - an array (table) of strings, specifying previous searches to automatically include in the search field menu, if searchPredefinedMenuTitle is not false searchHistoryAutosaveName - a string specifying the key name to save search history with in the application deafults (accessible through hs.settings). If this value is set, search history will be maintained through restarts of Hammerspoon. searchHistoryLimit - the maximum number of items to store in the search field history. searchPredefinedMenuTitle - a string or boolean specifying how a predefined list of search field "response" should be included in the search field menu. If this item is true, this list of items specified for searchPredefinedSearches will be displayed in a submenu with the title "Predefined Searches". If this item is a string, the list of items will be displayed in a submenu with the title specified by this string value. If this item is false, then the search field menu will only contain the items specified in searchPredefinedSearches and no search history will be included in the menu. searchPredefinedSearches - an array (table) of strings specifying the items to be listed in the predefined search submenu. If set to false, any existing menu will be removed and the search field menu will be reset to the default. searchReleaseFocusOnCallback - a boolean, default false, specifying whether or not focus leaves the search field text box when the callback is invoked. Setting this to true can be useful if you want subsequent keypresses to be caught by the webview after reacting to the value entered into the search field by the user. searchText - a string specifying the text to display in the search field. searchWidth - the width of the search field text entry box. selectable - a boolean value, default false, indicating whether or not this toolbar item is selectable (i.e. highlights, like a selected tab) when clicked on. Only one selectable toolbar item can be highlighted at a time, and you can get or set/reset the selected item with hs.webview.toolbar:selectedItem. tag - an integer value which can be used for own purposes; has no affect on the visual aspect of the item or its behavior. tooltip - a string label, or false to remove, which is displayed as a tool tip when the user hovers the mouse over the button or button group. If a button is in a group, it's tooltip is ignored in favor of the group tooltip.

allowedItems

Signature	hs.webview.toolbar:allowedItems() -> array
Type	Method
Description	Returns an array of all toolbar item identifiers defined for this toolbar.
Parameters	None
Returns	a table as an array of all toolbar item identifiers defined for this toolbar. See also hs.webview.toolbar:items and hs.webview.toolbar:visibleItems.

autosaves

| Signature | hs.webview.toolbar:autosaves([bool]) -> toolbarObject | bool | | -----------------------------------------------------|---------------------------------------------------------------------------------------------------------| | Type | Method | | Description | Get or set whether or not the toolbar autosaves changes made to the toolbar. | | Parameters |

• an optional boolean value indicating whether or not changes made to the visible toolbar items or their order is automatically saved.

| | Returns |

• if an argument is provided, returns the toolbar object; otherwise returns the current value

| | Notes |

• If the toolbar is set to autosave, then a user-defaults entry is created in org.hammerspoon.Hammerspoon domain with the key "NSToolbar Configuration XXX" where XXX is the toolbar identifier specified when the toolbar was created.
• The information saved for the toolbar consists of the following:
• the default item identifiers that are displayed when the toolbar is first created or when the user drags the default set from the customization panel.
• the current display mode (icon, text, both)
• the current size mode (regular, small)
• whether or not the toolbar is currently visible
• the currently shown identifiers and their order
• Note that the labels, icons, callback functions, etc. are not saved -- these are determined at toolbar creation time, by the hs.webview.toolbar:addItems, or by the hs.webview.toolbar:modifyItem method and can differ between invocations of toolbars with the same identifier and button identifiers.
