Configuring code style
If certain coding guidelines exist in a company, one has to follow these guidelines when creating source code. MPS helps you maintain the required code style.
The IDE comes with two pre-defined schemes: the Project scheme and the Default scheme.
In the Project scheme, the settings that you configure apply only to your current project.
These settings are stored in the codeStyles folder under .idea and are shared through VCS together with the project.
The IDE creates the folder after you modify code style settings for your project.
In the Default scheme (IDE-level scheme), the settings that you configure apply to all existing projects that have the Default code style scheme selected.
These settings are stored in the codestyles folder under the MPS configuration directory and are not shared through VCS.
If you want to use the project code style scheme as your default scheme, you can copy it to the IDE level. The other way around is also possible: you can overwrite your current project settings with the settings from an IDE-level scheme and share them with other members of your team.
Configure schemes
In MPS, code style settings are language-specific, so you need to configure them for every language that you use in your project separately. You can also copy the settings from one language and apply them to another language.
Configure code style for a language
Press Ctrl+Alt+S to open the IDE settings and select .
To configure a scheme for new projects, go to .
Select the language for which you want to configure the code style.
Select the code style Scheme that you want to configure: the Project scheme or one of the IDE-level schemes.
Browse through the tabs and configure code style preferences.
Use the right-hand section of the dialog to preview the changes. When you change a setting, one or several blinking areas appear in the preview area emphasizing the changes.
Apply code style from another language
For most of the supported languages, you can copy code style settings from other languages or frameworks.
Press Ctrl+Alt+S to open the IDE settings and select .
To configure a scheme for new projects, go to .
Select the language for which you want to configure the code style.
Select the code style Scheme that you want to modify: the Project scheme or one of the IDE-level schemes.
Click Set from in the upper-right corner.
The link is shown only if it's possible to apply code style settings from another language.
From the list that appears, select the language to copy the code style from.
