Install Cling

1. Download the Cling executable for your OS or install it using the following brew command: brew install cling.

Use Cling to interpret code

• You can call Cling-related actions from Tools | Cling on the main menu or via Help | Find Action (⌃ ⇧ A).

tip

Cling sessions start up with the flags collected for the currently opened file. This applies to both language standards and include paths.

Working directory for a Cling session

• If there is a file currently opened in the editor, its directory is used as a working directory for Cling. Related include paths from this file work as well when sent to the same session.

• Otherwise, AppCode uses the project root.

• If there is no project, the home directory is used.

Cling terminal

Upon any of the Cling actions, AppCode opens the dedicated terminal window.

You can type code in this window and also load the current file or reset/close the session using the toolbar buttons.
