A Go library providing a Decorated Syntax Tree (dst) that allows manipulation of Go source code with perfect fidelity, preserving comments, spacing, and formatting as nodes are modified. It serves as a drop-in alternative to go/ast for source-to-source transformations.

Use cases

• rewrite Go source code while preserving comments and formatting
• reorder or refactor Go statements without breaking comment attachment
• build automated Go code refactoring tools
• inject or modify comments in Go AST nodes
• convert between go/ast and a fidelity-preserving syntax tree
• generate Go code transformations for codemods

When to choose

• you need to programmatically modify Go source and keep comments and spacing intact
• go/ast round-tripping loses or misplaces comments in your transformations
• you are building a Go refactoring, linting, or codemod tool
• you need reliable parse-modify-print of Go code

When to avoid

• you only need to read or analyze Go code without modifying it - go/ast or go/types suffice
• you are working with languages other than Go
• you need type checking or semantic analysis - pair it with go/types instead
