YAML

Anchors and aliases

RubyMine supports working with anchors and aliases. If you specify a new anchor in the YAML file, the editor will show a warning that this anchor is not used by any node.

The editor enables you now to complete aliases for this anchor.

You can navigate from aliases to the anchor using the Ctrl+B shortcut.

For the anchor, you can do the same and find all corresponding aliases.

RubyMine also supports the rename refactoring for anchors and aliases.

Note that the Structure view Alt+7 allows you to manage whether to display nodes for aliases. Use the Show aliases sub-trees button to do this.

Remote JSON schemas

RubyMine supports code completion and inspections for YAML files using the specified JSON schema. For instance, if you use the .travis.yml file for Travis CI configuration, RubyMine will suggest completing its options using the JSON schema loaded from schemastore.org:

You can manage loading JSON schemas using the Languages & Frameworks | Schemas and DTDs | Remote JSON Schemas page of the Settings/Preferences dialog (Ctrl+Alt+S).

If necessary, you can specify a path to the required schema file in the Languages & Frameworks | Schemas and DTDs | JSON Schema Mappings page.

Copying keys

RubyMine provides the ability to copy a full path to a specific option specified in the YAML file. For instance, this can be useful when copying key paths from localization files. You can do this in two ways:

• Place a caret to the required key and press Ctrl+Alt+Shift+C.

• Hover over the required key, right-click it and select Copy Reference.

For the localization key on the image above, the en.likes.create.error value will be copied.

tip

You can search for nested YAML keys using flattened syntax. For instance, to find the error value in the example, press Shift twice and type en.likes.create.error.
