File and Code Templates

File templates are specifications of the default contents to be generated when creating a new file. Depending on the type of file you are creating, templates provide initial code and formatting that is expected to be in all files of that type (according to industry standards, your corporate policy, or for other reasons).

JetBrains Rider provides predefined templates for all supported file types, which are suggested when you are creating a new file.

File templates are managed on the Editor | File Templates | Other Languages page of JetBrains Rider settings (Ctrl+Alt+S) This settings page can be configured in one of two scopes:

  • The Default scope controls templates that pertain to the entire workspace. They are stored in the IDE configuration directory under fileTemplates.

  • The Project scope controls templates on a per-project basis. They are stored in the project folder under .idea/fileTemplates. These templates can be shared among team members.

By default, the list of templates contains only predefined templates provided by JetBrains Rider. Some of them are internal, which means they cannot be deleted or renamed. The names of internal templates are shown in bold. The names of templates that you modified, as well as custom templates that you created manually, are shown in blue.

JetBrains Rider uses several types of templates, separated into the following tabs:

  • The Files tab contains file templates that can be used for creating new files.

  • The Includes tab contains templates of reusable content that can be inserted into file templates (for example, as headers).

  • The Code tab contains internal templates for code fragments (snippets) used by JetBrains Rider for generating various constructs. You can edit the available snippets on this tab, but you cannot create new ones.

The following procedures describe how to create file templates. Similar procedures can be used for creating include templates.

To create a new file template

  1. Press Ctrl+Alt+S to open the Settings/Preferences dialog and then go to Editor | File Templates | Other Languages.

  2. On the Files tab, click Create Template (icons general add svg) and specify the name, file extension, and body of the template.

  3. Apply the changes and close the dialog box.

To copy an existing file template

  1. Press Ctrl+Alt+S to open the Settings/Preferences dialog and then go to Editor | File Templates | Other Languages.

  2. On the Files tab, click Copy Template (The Copy Template button) and modify the name, file extension, and body of the template as necessary.

  3. Apply the changes and close the dialog box.

To save a file as a template

  1. Open a file in the editor.

  2. Choose Tools | Save File as Template from the menu.

  3. In the Save File as Template dialog box that opens, specify the new template name and edit the body, if necessary.

  4. Apply the changes and close the dialog box.

Syntax

File and code templates are written in the Velocity Template Language (VTL), which enables using the following constructs:

  • Fixed text (markup, code, comments, etc.), which is rendered as-is.

  • Variables, which are replaced by their values.

  • Various directives, including #parse, #set, #if, and others.

Fore more information, see the VTL reference guide.

The following example shows the default template for creating a JavaScript class in JetBrains Rider:

/** * Created by ${USER} on ${DATE} */

In this template, ${USER} and ${DATE} are template variables.

When you create a new JavaScript file, this template generates a file with contents similar to the following:

/** * Created by John.Smith on 6/7/11 */
