Grammar

 expression := (variable|text)*
 variable := '${' expression '|' expression '}'
 text := // any characters except '${'
 

Examples

• Mixed expression: ${foo} and ${bar}
• Variable with default value: ${foo|bar}, ${foo|default value is ${bar}}
• Dynamic variable: ${${foo.name}}
• Etc. ${foo${bar|}|${other|${${fallback.name}}!}}

Note

The parser trim variable key and default value thus ${ foo | default } is equals to ${foo|default}.
