Perspective

A Perspective is a view into your OmniFocus database that appears in the perspective list (left-side of window) and whose contents are detailed in the outline (right-side of window).

OmniFocus comes with built-in perspectives (Perspective.BuiltIn class): Flagged, Forecast, Inbox, Nearby, Projects, Review, and Tags; and two transient reference perspectives: Completed and Changed. Custom perspectives (Perspective.Custom class) can be created in OmniFocus Pro.

Perspective Properties

Here are the properties of both the built-in and custom perspective classes:

The Class Properties of the Perspective.BuiltIn class:

• Flagged (Perspective.BuiltIn r/o) • The flagged items.

• Forecast (Perspective.BuiltIn r/o) • The upcoming due items.

• Inbox (Perspective.BuiltIn r/o) • The inbox of tasks.

• Nearby (Perspective.BuiltIn r/o) • Nearby items on a map (iOS only).

• Projects (Perspective.BuiltIn r/o) • The library of projects.

• Review (Perspective.BuiltIn r/o) • The projects needing review.

• Search (Perspective.BuiltIn r/o) • A search of the database. This perspective cannot be set, but might be reported if the user is searching.

• Tags (Perspective.BuiltIn r/o) • The hierarchy of tags.

• all (Array of Perspective.BuiltIn) • An array of all items of this enumeration. THis property is sometimes used when creating Action Forms.

The Instance Properties of the Perspective.BuiltIn class:

• name (String r/o) • The localized name of the built in perspective.

The Instance Properties of the Perspective.Custom class:

• identifier (String r/o) • The unique identifier for this custom perspective.

• name (String r/o) • The name of this custom perspective.

• all (Array of Perspective.Custom) • An array of all items of this enumeration. This property is sometimes used when creating Action Forms.

An instance of either the built-in or custom Perspective class is the value of the perspective property of the Window class.

The Perspective Property of a Window
Copy

document.windows[0].perspective
//--> [object Perspective.BuiltIn: Inbox]

Get the name of the current perspective:

Name of the Current Perspective
Copy

document.windows[0].perspective.name
//--> "Projects"

Change window view to show Inbox perspective:

Change Window to Inbox Perspective
Copy Run Script

document.windows[0].perspective = Perspective.BuiltIn.Inbox
//--> [object Perspective.BuiltIn: Inbox]

Perspectives can also be shown using the OmniFocus URL schema:

• omnifocus:///inbox
• omnifocus:///flagged
• omnifocus:///projects
• omnifocus:///tags

Show Projects Perspective
Copy Run Script

URL.fromString("omnifocus:///projects").open()

Custom Perspectives

Custom Perspectives are created by you to display items based upon the filtering parameters you define.

The properties of the Perspective.Custom class:

• iconColor (Color or null) • (4.5.2) The Color (Color documentation) that is applied to the perspective icon symbol. (Does not apply when a perspective uses a custom icon.)

• identifier (String r/o) • A unique identifying string assigned to the perspective instance. For example: “aS3jYumRtrm”

• name (String r/o) • The name of the custom perspective.

• all (Array of Perspective.Custom) • An array of all items of this enumeration. This property is sometimes used when creating Action Forms.

Changing Color of Custom Perspective Icon
Copy

cp = Perspective.Custom.byName("Executive Summary")
if(cp){cp.iconColor = Color.white}

The Class Functions of the Perspective.Custom class:

• byName(name:String) → (Perspective.Custom or null) • A custom perspective with the given name, if one exists. If there are multiple perspectives with the same name, it is not defined which will be returned.

• byIdentifier(uuid:String) → (Perspective.Custom or null) • The custom perspective with this identifier, if it exists. There is guaranteed to be at most one perspective with a given identifier.

The Instance Functions of the Perspective.Custom class:

• fileWrapper( ) → (FileWrapper) • Returns an archived file wrapper for the custom perspective. The file wrapper’s preferred filename will be the name of the perspective with an appropriate file extension applied. Its contents will include a plist representing the perspective’s settings, along with any image attachments needed to display its icon.

• writeFileRepresentationIntoDirectory(parentURL: URL) → (URL) • Writes the perspective’s fileWrapper() within a given parent directory URL, returning the URL of the saved FileWrapper. This function requires sandboxed access to the parent folder; it may be easier to work with the perspective’s fileWrapper(), which can be accessed directly or saved to disk using FileSaver.

Show a Custom Perspective
Copy

var p = Perspective.Custom.byName("Fairfield Project")
if(p){document.windows[0].perspective = p}

Showing Custom Perspective using a URL

To display a custom perspective, you may optionally incorporate the built-in URL support of OmniFocus in the script:

Show Custom Perspective
Copy

var name = "Fairfield Project"
var urlStr = "omnifocus:///perspective/" + encodeURIComponent(name)
URL.fromString(urlStr).open()

Export the Chosen Custom Perspective

Here is an example plug-in that will display a menu of all available custom perspectives, and then the chosen perspective to file on disk.

Add the Chosen Perspective

Here is the basic script for creating a new tab (macOS) or window (iPadOS) for a specified perspective:

New Tab/Window with Perspective
Copy

(async () => {		
	targetPerspective = Perspective.BuiltIn.Projects
	if (Device.current.mac){
		win = await document.newTabOnWindow(document.windows[0])
		win.perspective = targetPerspective
	} else {
		win = await document.newWindow()
		win.perspective = targetPerspective
	}
})().catch(err => console.error(err.message))

And a version where the chosen perspective is added to a new tab or window:

(async () => {
	// remove Search
	bPerspectives = Perspective.BuiltIn.all
	idx = bPerspectives.indexOf(Perspective.BuiltIn.Search)
	if (idx > -1) {
	  bPerspectives.splice(idx, 1);
	}
	bPerspectives.sort((a, b) => {
	  var x = a.name;
	  var y = b.name;
	  if (x < y) {return -1;}
	  if (x > y) {return 1;}
	  return 0;
	})
	bpNames = bPerspectives.map(p => p.name)

	cPerspectives = Perspective.Custom.all
	cPerspectives.sort((a, b) => {
	  var x = a.name;
	  var y = b.name;
	  if (x < y) {return -1;}
	  if (x > y) {return 1;}
	  return 0;
	})
	cpNames = cPerspectives.map(p => p.name)
	pNames = bpNames.concat(cpNames)
	itemIndexes = pNames.map((item, index) => index)
	pObjs = bPerspectives.concat(cPerspectives)

	perspectivesMenu = new Form.Field.Option(
		"perspective", 
		"Perspective", 
		itemIndexes, 
		pNames, 
		0
	)

	inputForm = new Form()
	inputForm.addField(perspectivesMenu)
	formPrompt = "Choose perspective to show:"
	buttonTitle = "Continue"
	formObject = await inputForm.show(formPrompt,buttonTitle)
	chosenIndex = formObject.values['perspective']
	chosenPerspective = pNames[chosenIndex]
	perspect = pObjs[chosenIndex]
	
	if (Device.current.mac){
		if(perspect === Perspective.BuiltIn.Nearby){
		 	throw new Error("Nearby not available on macOS")
		}
		var win = await document.newTabOnWindow(document.windows[0])
	} else {
		var win = await document.newWindow()
	}
	win.perspective = perspect
})().catch(err => new Alert(err.name, err.message).show())

Here is an example plug-in that will display a menu of all available perspectives, and then open the chosen perspective in a new tab (macOS) or a new window (iOS and iPadOS).

(⬆ see above ) The Add Chosen Perspective plug-in has no contextual selection requirements so it is available in the Share menu when no elements are selected in the app interface.

Adjusting Filter Rules using Omni Automation

Beginning with OmniFocus v4.2 the Perspective.Custom class now has two new instance properties that provide access to the filter rules of custom perspectives:

• archivedFilterRules (Object) • For a custom perspective, archivedFilterRules holds a JSON archive representing the perspective’s rules. These rules will be interpreted differently based on the archivedTopLevelFilterAggregation setting.

• archivedTopLevelFilterAggregation (String or null) • For a custom perspective, the archivedTopLevelFilterAggregation indicates which aggregation method is being used to interpret the archivedFilterRules: “all”, “any”, or “none”

Using these new properties, you can both access and alter the filtering rules for a custom perspective using Omni Automation:

Getting Rules for Current Custom Perspective
Copy

document.windows[0].perspective.archivedTopLevelFilterAggregation
//--> "all"
			
document.windows[0].perspective.archivedFilterRules
//--> [{actionAvailability: "available"}, {actionHasAnyOfTags: ["ni5R6QIk4aO"]}]

Version of the previous script that uses the JSON.stringify() function to display the results in the console as formatted JSON:

Getting Rules for Current Custom Perspective
Copy

agg = document.windows[0].perspective.archivedTopLevelFilterAggregation
console.log(agg)

rulesArchive = document.windows[0].perspective.archivedFilterRules
console.log(JSON.stringify(rulesArchive, undefined, 2))
/*
	[
		{
			"actionAvailability": "available"
		},
		{
			"actionHasAnyOfTags": [
				"ni5R6QIk4aO"
			]
		}
	]
*/

The following script alters the value of the actionAvailability filter while retaining the value of the actionHasAnyOfTags filter:

Changing Rules for Current Custom Perspective
Copy

tagID = flattenedTags.byName("Special").id.primaryKey
currentPerspective = document.windows[0].perspective
currentPerspective.archivedFilterRules = [{actionAvailability: "remaining"}, {actionHasAnyOfTags: [tagID]}]

The following script demonstrates a function that changes just the value of a specific rule in the currently displayed custom perspective:

Changing Value of a Specified Rule
Copy

function changeValueForRule(ruleName, ruleValue){
	cp = document.windows[0].perspective
	rulesObjArray = cp.archivedFilterRules
	for (rulesObj of rulesObjArray){
		if (rulesObj.hasOwnProperty(ruleName)){
			rulesObj[ruleName] = ruleValue
			break
		}
	}
	cp.archivedFilterRules = rulesObjArray
}
// Pass the rule and new value to function
changeValueForRule("actionAvailability", "available")

This variation of the previous function will either change the value of the specified rule if the rule exists in the archive, or add the rule with the indicated value if the rule does not currently exist in the archive.

Set Value of a Specified Rule
Copy

function setValueForRule(ruleName, ruleValue){
	cp = document.windows[0].perspective
	rulesObjArray = cp.archivedFilterRules
	didChange = false
	for (rulesObj of rulesObjArray){
		if (rulesObj.hasOwnProperty(ruleName)){
			rulesObj[ruleName] = ruleValue
			didChange = true
			console.log("Changing value…")
			break
		}
	}
	if(!didChange){
		console.log("Added rule…")
		obj = new Object()
		obj[ruleName] = ruleValue
		rulesObjArray.push(obj)
	}
	console.log(JSON.stringify(rulesObjArray, undefined, 2))
	cp.archivedFilterRules = rulesObjArray
}
// Pass the rule and new value to function
setValueForRule("actionHasNoProject", true)

Filter Rules and Values

Here are the variations of possible filter rules and their values:
