AppCode 2017.3 Help

JavaScript Documentation Look-Up

AppCode lets you get reference for standard JavaScript APIs, for symbols from your project and from its dependencies, as well as for symbols defined in external libraries. The documentation is shown in a Documentation pop-up window that helps navigate to the related symbols via hyperlinks, and provides a toolbar for moving back and forth through the already navigated pages.

To view documentation for a symbol at caret
Press F1 or choose View | Quick Documentation Lookup on the main menu. The reference for the symbol is shown in the Documentation pop-up window.

  • For a project symbol or for a symbol from the project dependencies, AppCode generates the documentation from the corresponding JSDoc comment.
  • For a standard JavaScript object or method, AppCode shows the corresponding JSDoc comment from the built-in TypeScript definition files (d.ts). These files are bundled with AppCode and updated on a regular basis.
  • If no comment is found in the d.ts files, AppCode shows a summary from the corresponding MDN article.

To view the MDN documentation for a symbol at caret

  • In the Documentation window (F1), click arrowUp.
  • Alternatively
    Press ⇧F1 or choose View | External Documentation on the main menu.

To view documentation for a third-party JavaScript library

  1. Download the required library or framework, configure it as an external JavaScript library, and specify the link to its external documentation, see Configuring a custom third-party JavaScript library for details.
  2. Position the cursor at the symbol in question and press ⇧F1 or choose View | External Documentation on the main menu.

To show documentation automatically

  1. In the Settings/Preferences dialog (⌘,), click General under Editor, then click Code Completion. The Code Completion page opens.
  2. Select the Auto-display documentation checkbox and specify the elapsed time.

To change the font size of quick documentation

  • Click show slider in the upper-right corner of the quick documentation window, and move the slider.
  • Alternatively
    In the Settings/Preferences dialog (⌘,), click General under Editor and select the Change font size (Zoom) with Ctrl+Mouse Wheel checkbox.
