Pulumi Configuration Language (PCL)

Pulumi Configuration Language (PCL) is an internal representation of Pulumi programs which supports all core concepts of the Pulumi programming model in a minimal form. Although not exposed directly to users today, this intermediate representation is used to support a variety of program conversion tasks, from and to various supported Pulumi languages.

Pulumi supports a number of operations pertaining to PCL programs:

  • Lexing and parsing, in which PCL source is parsed into an abstract syntax tree (AST).

  • Type checking and binding, in which a PCL AST is verified to be well-formed (describing resources, outputs, and so on), associated with ("bound to") a set of Pulumi schema, and type checked and resolved.

  • Code generation ("programgen"), in which a PCL program is converted into a program written in a supported target language. Much of this underpins the core of tools such as pulumi convert.
