Code insight for YAML anchors and aliases

Autocompletion

Once you’ve defined an anchor in your document, you can autocomplete its aliases simply by pressing Enter, instead of typing them out:

Code navigation

This trademark feature of all JetBrains IDEs now works for aliases. Press Cmd+click / Ctrl+click on an alias to navigate to its anchor definition. Back-click on an anchor to see the list of its aliases and navigate to any of them:

Find usages

Usages of aliases can now be found just like Ruby variables, parameters, and methods: put your caret to an alias, and choose Find usages from the context menu. Alternatively, press Alt+F7:

Inline renaming

Inline renaming aliases and their anchors is also available now. As usual, put the caret on an alias or an anchor, and go to Refactor | Rename. Or simply press Shift+F6:

By the way, RubyMine will warn you if you try to provide a name that is already used for another anchor if this creates conflicts:

Also, the IDE will not allow you to rename acnhors using characters that aren’t allowed by the standard. For instance, if you try to insert a space and save the new name, it will suggest that you continue editing the name, or cancel the process:

Inspections

In addition to code completion and navigation, we’ve added a number of YAML inspections:

First of all, RubyMine will warn you if you try to define multiple anchors or tags:

The IDE will also report an error if you provide an alias that doesn’t have an anchor:

Finally, RubyMine will catch and report recursions:

More intention actions for Ruby

In this build, you will also discover improved intention actions for conditional statements. For instance, RubyMine now suggests replacing `while` with `until`:

The IDE also helps replace bad-style negative statements, like this one:
