Tabs and Indents
|Use tab character|| |
|Smart tabs|| |
The Smart Tabs checkbox is available if the Use Tab Character checkbox 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 checkbox is selected) to be inserted for each indent level.|
|Keep indents on empty lines||If this checkbox is selected, then GoLand will keep indents on the empty lines as if they contained some code.|
If this checkbox is not selected, GoLand will delete the tab characters and spaces.
|Label indent||In this text box, specify the number of spaces (or tabs if the Use Tab Character checkbox is selected) to be inserted at the next line before a label statement.|
|Absolute label indent||If this checkbox is selected, label indentation is counted as an absolute number of spaces. Otherwise, label indentation is counted relative to previous indent levels.|
|Do not indent top level class members||Select this checkbox to have top level class members located at the class declaration indentation level.|
|Use indents relative to expression start||Use this checkbox to switch between the two possible indentation behaviors: |
Use this tab to specify where you want spaces in your code. To have GoLand automatically insert a space at a location, select the checkbox 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 GoLand 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 the Hard wrap at 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 the Wrap on typing settings to specify how the edited text is fitted in the specified Hard wrap at. You can select one the following options:
- Default - in this case GoLand uses the Wrap on typing option that is specified in the global settings.
- Yes - in this case GoLand 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.
Use the Visual guides field to specify multiple right margins. You can leave a default value or enter the number of spaces for your margin. If you want to specify several margins, enter numbers separated by comma.
Keep when reformatting
Use the checkboxes to configure exceptions that GoLand will make when reformatting the source code. For example, by default, the Line breaks checkbox 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.
The wrapping style applies to the various code constructs, specified in the left-hand pane (for example, method call arguments, or assignment statements).
|Wrapping style||From this drop-down list, select the desired wrapping style: |
|Align when multiline||If this checkbox 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.|
|Select this checkbox to have the specified character or characters moved to the next line when the lines are wrapped.|
|'else' on new line||Use this checkbox to have the corresponding statements or characters moved to the next line.|
|New line after ||Select this checkbox to have the code after the specified character moved to a new line.|
|Special else if treatment||If this checkbox is selected, |
|Indent case branches|| If this checkbox 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 GoLand 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.
|Alignment||In this area, define how JavaDoc comments should be aligned. |
|Blank Lines||In this area, define where blank lines should be inserted in JavaDoc comments. |
|Invalid Tags||In this area, define whether invalid tags should be preserved or not. |
|Other||In this area, specify additional formatting options for JavaDoc comments. |
This tab lets you define a set of rules that rearranges your code according to your preferences.
|Grouping Rules||Use this area to set the grouping rules. |
|Matching rules||Use this area to define elements order as a list of rules, where every rule has a set of matches such as modifier or type. |
|Empty rule||Use this area to create a new matching rule or edit an existing one. You can select from the following filters: |
|This icon appears when you select Order by Name from the Order list. The icon indicates that the items in this rule are sorted alphabetically.|
This table lists actions to be performed when imports are optimized.
|Final Modifier||Options: |

Java EE Names
Use this tab to specify prefixes and suffixes for the names of bean classes, bean interfaces,
<ejb-name> tags, servlets, filters, and listeners. These prefixes and suffixes will by default appear in the corresponding fields of the New Bean, New Servlet, New Filter, and New Listener dialog boxes. For entity beans, you can also specify the default primary key class that appears in the dialog box.
|Entity Bean||Use the text boxes in this area to specify prefixes and/or suffixes to be used in the names of Entity Bean components: |
|Session Bean|| Use the text boxes in this area to specify prefixes and/or suffixes to be used in the names of Session Bean components: |
|Message Driven Bean|| Use the text boxes in this area to specify prefixes and/or suffixes to be used in the names of Message Driven Bean components: |
|Servlet||Use the text boxes in this area to specify prefixes and/or suffixes to be used in the names of Servlets: |
|Filter||Use the text boxes in this area to specify prefixes and/or suffixes to be used in the names of Filters: |
|Listener||In this area, specify the prefix and suffix to be used in the names of listener classes.|
