The Benthos extension for Visual Studio Code adds syntax highlighting support for the Bloblang language within YAML files (.yaml/.yml) and mapping files (.blobl).

Bloblang string interpolations and environment variable references should get enhanced with syntax highlighting.

Syntax highlighting for plugins or plugin config fields that accept bloblang mappings can be enabled using the #!blobl pragma as the first line. Here's an example when using the mapping processor:

pipelines:
  processors:
    - mapping: |
        #!blobl
        root.name = this.
          (fullName | nickName).
          not_empty().
          catch(err -> "failed to get pet name: %s".format(err))

        root.sound = if this.type == "cat" {
          this.cat.meow
        } else if this.type == "dog" {
          this.dog.woof.uppercase()
        } else {
          "sweet sweet silence"
        }
    - log:
        level: ${LOG_LEVEL:INFO}
        message: '${! this.name } sounds like ${! this.sound.or("nothing") }'

This snippet would look something like the following screenshot with this extension installed in VS Code.
