class MachineName

Creates a machine name.

The machine_name process plugin takes the source value and runs it through the transliteration service. This makes the source value lowercase, replaces anything that is not a number or a letter with an underscore, and removes duplicate underscores.

Letters will have language decorations and accents removed.

Example:


process:
  bar:
    plugin: machine_name
    source: foo

If the value of foo in the source is 'áéí!' then the destination value of bar will be 'aei_'.

Plugin annotation


@MigrateProcessPlugin(
  id = "machine_name"
)
