Kaleidoscope Prism

Kaleidoscope Prism is a separate app that lives in the menubar by default. It's made to help you get your content into Kaleidoscope even quicker and easier.

Features

Menubar icon

In its default configuration, Kaleidoscope Prism shows an icon in the menubar. That icon can be used to drop content onto it. Just drop files or text onto that icon, as you would onto the Kaleidoscope icon in the Dock and that content will be opened in Kaleidoscope. Clicking the icon shows the Kaleidoscope Prism menu by default.

Drop Window

The Kaleidoscope Prism Drop Window can be shown in many ways, see Settings below. When visible, it can also be used to drop content onto it. Again, that content will be opened in Kaleidoscope.

Menu

Kaleidoscope Prism features a menu that will be shown from the menubar icon by default (see Settings) and also from the top right button of the Drop Window.

All menu commands are particularly useful in combination with a keyboard shortcut that can be set via Settings > Shortcuts, see below.

Show/Hide Kaleidoscope Prism

Use this command to toggle visibility of the Prism (Drop) Window.

Compare Finder Selection

Select this menu command to immediately open the files currently selected in the Finder in a new comparison in Kaleidoscope.

Add a keyboard shortcut to this command to have a "single-click" solution for comparing files.

Send Clipboard group

Kaleidoscope Prism provides two commands that can be invoked from the menu or via keyboard shortcut.

Send Clipboard to Front Document

In combination with the command above, this can be a very quick way to compare things using Kaleidoscope. This command will send the current clipboard contents to the frontmost Kaleidoscope document.

Send Clipboard to New Comparison

This command will open the current clipboard contents in a new comparison in Kaleidoscope.

Send Clipboard to New Changeset

When text on the clipboard has the format of a (short) Git commit identifier (also named hash or SHA), this command lets you open a changeset for the identified commit.

Note: The repository containing the commit with that identifier needs to be known to Kaleidoscope (in Repositories) for this command to work as expected.

Settings, Open Kaleidoscope, Quit

Use these commands to show Kaleidoscope Prism’s own settings (see below), to open Kaleidoscope, and to quit Kaleidoscope Prism.

Note that the main Kaleidoscope app has a Setting to control whether and when Kaleidoscope Prism should be started.


Kaleidoscope Prism Settings

The real power of Kaleidoscope Prism comes from its ability to adapt to your needs. Adjust its settings to best fit your workflow. There are two ways to get to the settings:

  • From the menu bar, select > Settings…

  • From the Kaleidoscope Prism window, select > Settings…

General

Show Icon

When disabled, the icon in the menubar will no longer be shown. We strongly advise to set a keyboard shortcut to toggle the Prism Window when using that setting, so you have a way to get back to the settings.

On Click …

Here you can decide whether a click on the menubar icon should show the menu or rather toggle the Prism Window. Note that the menu is also available from the top right button of the Prism Window.

Show Prism Window

Set the Prism Window to be only shown when manually triggered, or also automatically when starting to drag something. For the second option, you can decide whether to show the window in its default location (where you last put it) or near the mouse pointer where you started dragging.

Shortcuts

All shortcuts set here are global, meaning they are potentially available in any other app. That also means they could conflict with many other shortcuts.

Toggle Prism Window

Set a shortcut to show and hide the Prism Window.

Compare Finder Selection

Using this shortcut anywhere, but in particularly in Finder, will take the files selected in the Finder and open them in a new comparison in Kaleidoscope.

Send Clipboard

These shortcuts make a lot of sense when combined, as the enable a very quick workflow to create several new comparisons.
