GoLand 2021.1 Help

Code style

If certain coding guidelines exist in a company, one has to follow these guidelines when creating source code. GoLand helps you maintain the required code style.

Code styles are defined at the project level and at the IDE level (global).

  • At the project level, settings are grouped under the Project scheme, which is predefined and is marked in bold. The Project style scheme is applied to the current project only.

    You can copy the Project scheme to the IDE level, using the Copy to IDE command.

  • At the IDE level, settings are grouped under the predefined Default scheme (marked in bold), and any other scheme created by the user by the Duplicate command (marked as plain text). Global settings are used when the user doesn't want to keep code style settings with the project and share them.

    You can copy the IDE scheme to the current project, using the Copy to Project command.

Configure code style for a language

  1. Press Ctrl+Alt+S to open IDE settings and select Editor | Code Style.

  2. Select the language-specific settings page.

  3. Choose the code style Scheme to be used as a base for your custom code style for the selected language.

  4. Browse through the tabs of the selected language page, and configure code style preferences for it.

Copy code style settings from other languages

For most of the supported languages, you can copy code style settings from other languages or frameworks.

  1. Press Ctrl+Alt+S to open IDE settings and select Editor | Code Style.

  2. Select the language-specific settings page.

  3. Click Set From in the upper-right corner.

    The link is shown for those languages only, where defining settings on the base of other languages is applicable.

  4. From the list that appears, select the language to copy the code style from.

Disable code formatting in a scope

  1. In Settings/Preferences Ctrl+Alt+S, select Editor | Code Style.

  2. Click Formatter Control.

  3. Ensure that you selected a right scheme in the Scheme list.

  4. In the Do not format, optimize imports, arrange code pane, Click Add.

  5. In the Scopes dialog, click Add and select a scope. Select Local if the scope is intended for a personal use only. If you plan to share settings with team members, select Shared.

  6. Click OK.

  7. In the project tree, select the folder where you want to disable formatting and click Include.

  8. Click OK.

Manage code style on a directory level with EditorConfig

GoLand allows you to manage all code style settings for each individual set of files with EditorConfig support (enabled by default in the Settings/Preferences dialog Ctrl+Alt+S). All you need to do is place an .editorconfig file in the root directory containing the files whose code style you want to define. You can have as many .editorconfig files within a project as needed, so you can specify different styles for different modules.

All options from the .editorconfig file are applied to the directory where it resides as well as all of its sub-directories on top of the current project code style. If anything is not defined in .editorconfig, it's taken from the project settings.

All options in the .editorconfig file are divided into the following categories:

  • Standard options such as indent_size, indent_style, and so on. These options do not have any domain specific prefixes.

  • Generic IntelliJ options that have the ij_ prefix and are applicable to all languages:

    • ij_visual_guides

    • ij_formatter_off_tag

    • ij_formatter_on_tag

    • ij_formatter_tags_enabled

    • ij_wrap_on_typing

    • ij_continuation_indent_size

    • ij_smart_tabs

  • Common IntelliJ options supported by many (but not all) languages. They start with the ij_any prefix, for example, ij_any_brace_style.

  • IntelliJ language-specific options starting with the ij_<lang>_ prefix where <lang> is the language domain ID (normally a low-case language name), for example, ij_java_blank_lines_after_imports.

Add an .editorconfig file

  1. In the Project view, right-click a source directory containing the files whose code style you want to define and choose New | EditorConfig from the context menu.

  2. Select the properties that you want to define so that GoLand creates stubs for them, or leave all checkboxes empty to add the required properties manually.

  3. To preview how changes to your code style settings will impact the actual source files, click the eye icon in the gutter of the .editorconfig file and select a source file affected by it. The preview will open on the right.

    You can make changes in the preview pane to try and test how your configuration changes are reflected without worrying about making unwanted changes to the source code: all these changes are discarded when you close the .editorconfig file.

Productivity tips

Wrap call arguments, function parameters, and composite literal elements

  • To configure wrapping for call arguments, function parameters, and composite literal elements, open settings by pressing Ctrl+Alt+S and navigate to Editor | Code Style | Go | Wrapping and Braces.

Wrap arguments by using intention actions

  • To wrap arguments in the function signature, place the caret before the opening bracket, call the intention action by pressing Alt+Enter, and select Put arguments on separate lines. To revert this action, press Alt+Enter and select Put arguments on one line.
