Description

PreviewYaml provides QuickLook file previews and file icon thumbnails for documents created using the popular YAML structured data format.

The app provides two app extensions: Yaml Previewer and Yaml Thumbnailer, which can be viewed and managed in macOS’ System Preferences > Extensions > QuickLook. The app itself is simply a container for these extensions, and can be used to set preview preferences.

You must run the app first to gain these benefits.

Certain YAML features, such as custom tags, are not as yet supported by PreviewYAML.

Known issue: a YAML file containing .nan, .inf and/or .-inf values will prevent PreviewYAML from rendering the file. This issue is under investigation.
