Keep existing formatting

You can select formatting rules which will be ignored when you reformat the code. For example, you can adjust the IDE to keep simple methods and functions in one line, whereas normally they are expanded into multiple lines after code reformatting.

  1. Go to Preferences | Editor | Code Style, select your programming language, and open the Wrapping and Braces tab.

  2. In the Keep when reformatting section, select the formatting rules which you want to ignore and deselect those which should be applied.

AppCode will reformat your code in accordance with the current style settings, keeping existing formatting for the rules which you've selected.

Rearrange code entries

You can rearrange your code according to the arrangement rules set on the Arrangement tab located in Preferences | Editor | Code Style.

Code Style settings

For example, if you need to sort your code entries alphabetically, select the appropriate matching rules entry and set the Order field to order by name.

Matching rules example
  • In the editor, select the code entries you want to rearrange and from the main menu, select Code | Rearrange Code.

Configure comments formatting

In AppCode, you can adjust the way the generated line (⌘/) and block (⌥⌘/) comments will look like.

  • Comments position

    To place the comment characters at the first column, in Preferences | Editor | Code Style | C/C++/Objective-C (or Swift), open the Code Generation tab and select Line comment at the first column or Block comment at the first column.

    To align the comment characters with the next code line, deselect these checkboxes.

    When adding the block comments, note that the /* and */ characters appear at the beginning and at the end of the selection. To have these characters above and below a code block, you should select the block as a code construct (⌥↑/⌥↓).

  • Leading spaces in line comments

    To add a leading space in line comments, in Preferences | Editor | Code Style | C/C++/Objective-C (or Swift), open the Code Generation tab add select Add a space at comment start.

    Without space

    With space

    //comment your code //without spaces
    // comment your code // with spaces

    The option is available only when the Line comment at the first column checkbox is cleared.
