CVU: supported view definitions

The following view definitions are currently supported in CVU.


[sessions = "name"] {
    [session] {


[session = "name"] {
    [view] {


selector based on a list of the same types

Person[] {
    title: "{firstName} {lastName}"

Use *[] to apply to a list of any datatypes Use mixed[] to apply to a list of mixed datatypes

selector based on the data item type and its properties

Person {
    title: "{firstName} {lastName}"

Use * to apply to any data item


[renderer = list] {
    press: openView


Selects where data is loaded from, to display in this view.

[datasource = pod] {
    query: "Person"


The CVU language has built-in support for named colors that support dark and light mode. These colors can be defined using a color selector and can then be used in place of #333 style literal colors. In fact literal colors in views are highly discouraged. Users of views can override named colors in their settings, which they cannot do for literal colors.

[color = "background"] {
    light: #330000
    dark: #ff0000

[color = "highlight"] {
    light: #000
    dark: #fff


Similarly styles can be combined into named sets that can then be applied to UI elements.

[style = "my-label-text"] {
    border: background 1
    color: highlight

/* Example usage */
Text {
    style: my-label-text


Language selectors are used to specify text used in views in various natural languages, by replacing the text with variables. Here’s an example:

[language = "English"] {
    sharewith: "Share with..."
    addtolist: "Add to list..."
    duplicate: "Duplicate"
    showtimeline: "Show Timeline"
    timelineof: "Timeline of this"
    starred: "Starred"
    all: "All"
[language = "Dutch"] {
    sharewith: "Deel met..."
    addtolist: "Voeg toe aan lijst..."
    duplicate: "Dupliceer"
    showtimeline: "Toon Tijdslijn"
    timelineof: "Tijdslijn van deze"
    starred: "Favoriete"
    all: "Alle"

/* Example usage */
Text {
    text: "$sharewith"
