Simple, Parameterized and Surround Live Templates

Simple live templates

Simple templates contain some fixed code that expands into plain text. When invoked and expanded in the editor, the code specified in the template is automatically inserted into your source code, replacing the abbreviation.

Parameterized live templates

Parameterized templates contain plain text and variables that enable user input.

After a template is expanded, variables appear in the editor as input fields whose values can be either filled in by the user or calculated by AppCode automatically.

When a parameterized live template is invoked and expanded in the Editor, AppCode can suggest some predefined values at the input positions of the variables. For example, if a parameterized template contains code for an iteration, then, on expanding the template, AppCode will suggest:

  • A name for the index variable (i, j, etc.).
  • A list of all suitable variables in the current scope (e.g. Arrays) as an expression for the iterated container.
  • A name for the assigned variable that holds the current container element.
  • Type of the elements in the iterated container.

Surround live templates

Surround templates work only with blocks of selected text. Such templates place code before and after the selected block.
