The YAML Format

YAML in TYPO3

The use of YAML in  TYPO3 requires the following:

  • yaml ending
  • the 2-spaces rule must be observed, i.e. indentations for subcategories must consist of exactly two spaces
  • the character set of the file must be UTF-8
  • the specifications are case-sensitive, i.e. there is a distinction between upper and lower case.

YAML is used as a configuration format in various places in TYPO3.

Examples are:

  • the site configuration (see Multi-Site-ability from TYPO3)
  • the configuration and definition of forms in the system extension Forms
  • the configuration of the Rich Text Editor (RTE)
