AppCode 2021.2 Help

Icon reference

Many entities in AppCode are marked with icons: there are icons on toolbar buttons, in the gutter, in the Project tool window, and so on. The majority of icons have tooltips that allow you to quickly grasp their meaning. Hover the mouse over an icon and wait for the tooltip with some brief information.

Tooltips in the IDE

Gutter icons

Gutter icons are located in the editor on the left. Every icon in the gutter has a tooltip that explains its meaning.

Icons in the gutter

The list of available gutter icons depends on the configuration of your project, the frameworks that you use, and the plugins that you have installed. To access the list of gutter icons available for your project, go to Preferences | Editor | General | Gutter Icons.

For more information on gutter icons, refer to Gutter Icons.

Breakpoints

Breakpoints are special markers that suspend program execution at a specific point. This lets you examine the program state and behavior.

Depending on their type and status, breakpoints are marked with different icons in the gutter. For the full list of icons, refer to Breakpoint icons.

Bookmarks

If you want to return to some place in your code later, you can mark any code line with a bookmark.

There are two types of bookmarks: anonymous bookmarks Anonymous bookmark and bookmarks with mnemonics (lettered Lettered bookmark and numbered Numbered bookmark). For more information on how to work with bookmarks, refer to Use bookmarks for navigation.

Toolbar icons

AppCode has many tool windows, and almost every tool window has a toolbar with buttons. If you want to know what action a button performs, hover the mouse pointer over it to display a tooltip with the action name.

File status markers (VSC)

If your project is under version control, you can track uncommitted changes in a file by looking at the color indicators in the gutter. New, modified, and deleted lines have special markers by clicking on which you can open a diff, revert the changes, and perform other VCS-related actions. For more information, refer to Track changes to a file in the editor.

Line status colors shown in the editor

Colors in the Project tool window

Some files in the Project tool window have a colored background. For example, non-project files have a yellow background.

You can disable the colored background or configure colors for other groups of files. For more information, refer to Scopes and file colors.

Colors in the Project tool window

Some files in the Project tool window might be displayed in different colors, for example, in brown or olive. These colors reflect file statuses in your VCS: the brown color is used for new files that are not yet added to the VCS, olive is used for ignored files, and so on. For more information, refer to File Status Highlights.

File type icons

Each file format in AppCode has a dedicated icon. In the Project tool window (⌥1), these icons help you quickly identify with what kind of files you are working with. To view the list of file types recognized by AppCode and their icons, in the Preferences dialog ⌃⌥S, go to Editor | File Types.

File type settings

If a file in your project is marked with the Unknown file type icon, it indicates that AppCode can't recognize it. In this case, you can register and configure a new file type.

Code Coverage markers

When you run tests with coverage, the results of the coverage analysis are displayed in the gutter. The IDE highlights the lines of code according to their code coverage status in green, red, or yellow. For more information, refer to Code coverage.
