Class Method Details

.file?(file) ⇒ Boolean

Provides a simplistic way to check if a file is a YAML formatted file:

YAML.file?('project.yaml')  #=> true
YAML.file?('project.xml')   #=> false

Note this isn’t perfect. At present it depends on the use use of an initial document separator (eg. ‘—’). With YAML 1.1 the %YAML delaration is supposed to be manditory, so in the future this can be adapted to fit that standard.

Returns:

  • (Boolean)
