Internal package. This package is an implementation detail of prisma-next and is published only to support its runtime. Its API is unstable and may change without notice. Do not depend on this package directly; install prisma-next instead.

Prints Prisma Schema Language (PSL) from PslDocumentAst (@prisma-next/framework-components/psl-ast).

Overview

@prisma-next/psl-printer renders deterministic PSL text from a PslDocumentAst (defined in @prisma-next/framework-components/psl-ast). The package is target-agnostic: SQL → AST construction lives in the SQL family (@prisma-next/family-sql's inferPslContract capability).

Responsibilities

Convert structured AST (model, field, enum, types) into valid PSL output.
Preserve @map / @@map and relation attributes from AST nodes.
Generate deterministic output so snapshot-based tests remain stable.

Dependencies

Depends on
- @prisma-next/framework-components
Used by
- @prisma-next/cli (consumes printPsl(ast) after the SQL family produces the AST)
- @prisma-next/family-sql (tests; consumes the printer to verify AST construction)
