Click this link to reveal the list of languages to be used as the base for the current language code style. So doing, only the settings that are applicable to the current language are taken. All the other settings are not affected.

Tabs and Indents
|Use tab character|| |
|Smart tabs|| |
The Smart Tabs check box is available if the Use Tab Character check box is selected.
|Tab size||In this text box, specify the number of spaces included in a tab.|
|Indent||In this text box, specify the number of spaces (or tabs if the Use Tab Character check box is selected) to be inserted for each indent level.|
|Continuation indent||In this text box, specify the number of spaces (or tabs if the Use Tab Character check box is selected) to be inserted between the elements of an array, in expressions, method declarations and method calls.|
|Keep indents on empty lines||If this check box is selected, then AppCode will keep indents on the empty lines as if they contained some code.|
If this check box is not selected, AppCode will delete the tab characters and spaces.
Use this tab to specify where you want spaces in your code. To have AppCode automatically insert a space at a location, select the check box next to this location in the list. The results are displayed in the Preview pane.
Wrapping and braces
In this tab, customize the code style options, which AppCode will apply on reformatting the source code. The left-hand pane contains the list of exceptions (Keep when reformatting), and placement and alignment options for the various code constructs (lists, statements, operations, annotations, etc.) The right-hand pane shows preview.
Alignment takes precedence over indentation options.
Right Margin (columns)
Use Right Margin field to specify a margin space required on the right side of an element. If you select Default option then a value of the right margin from the global settings is used.
Wrap on typing
Use Wrap on typing settings to specify how the edited text is fitted in the specified Right margin. You can select one the following options:
- Default - in this case AppCode uses the Wrap on typing option that is specified in the global settings.
- Yes - in this case AppCode uses the value specified in the Right Margin field.
- No - in this case this option is switched off and a line can exceed the value specified in the right margin.
Keep when reformatting
Use the check boxes to configure exceptions that AppCode will make when reformatting the source code. For example, by default, the Line breaks check box is selected. If your code contains lines that are shorter than a standard convention, you can convert them by disabling the Line breaks check box before you reformat the source code.
|Wrapping style||Wrap after modifier list: wrap the modifier list on next line, indent as the first modifier character.|
|Align when multiline||If this check box is selected, a code construct starts at the same column on each next line. Otherwise, the position of a code construct is determined by the current indentation level.|
|Align parenthesised when multiline||If this check box is selected, a parenthesised code construct starts at the column of the opening parenthesis each next line. Otherwise, the position of a code construct is determined by the current indentation level.|
|Align in columns|| If this check box is selected, the variables names, types and initializers are aligned in columns, each variable on next line, as in example: |
|'else' on new line||Use this check box to have the corresponding statements or characters moved to the next line.|
|Special else if treatment||If this check box is selected, |
|Indent case branches|| If this check box is selected, the |
Braces placement options
|Braces placement style|| Use this drop-down list to specify the position of the opening brace in class declarations, method declarations, and other types of declarations. The available options are: |
|Force braces||From this drop-down list, choose the braces introduction method for |
Use this tab to define where and how many blank lines you want AppCode to retain and insert in your code after reformatting. For each type of location, specify the number of blank lines to be inserted. The results are displayed in the Preview pane.
|Keep Maximum Blank Lines||In this area, specify the number of blank lines to be kept after reformatting in the specified locations.|
|Minimum Blank Lines||In the text boxes in this area, specify the number of blank lines to be present in the specified locations. |
These settings do not influence the number of blank lines before the first and after the last item.
