package astutil

import "cuelang.org/go/internal/golangorgx/gopls/util/astutil"

Package astutil provides various AST utility functions for gopls.

Index ¶

• func NodeContains(n ast.Node, pos token.Pos) bool
• func PurgeFuncBodies(src []byte) []byte
• func UnpackRecv(rtyp ast.Expr) (ptr bool, rname *ast.Ident, tparams []*ast.Ident)

Functions ¶

func NodeContains ¶

func NodeContains(n ast.Node, pos token.Pos) bool

NodeContains returns true if a node encloses a given position pos.

Precondition: n must not be nil.

func PurgeFuncBodies ¶

func PurgeFuncBodies(src []byte) []byte

PurgeFuncBodies returns a copy of src in which the contents of each outermost {...} region except struct and interface types have been deleted. This reduces the amount of work required to parse the top-level declarations.

PurgeFuncBodies does not preserve newlines or position information. Also, if the input is invalid, parsing the output of PurgeFuncBodies may result in a different tree due to its effects on parser error recovery.

func UnpackRecv ¶

func UnpackRecv(rtyp ast.Expr) (ptr bool, rname *ast.Ident, tparams []*ast.Ident)

UnpackRecv unpacks a receiver type expression, reporting whether it is a pointer recever, along with the type name identifier and any receiver type parameter identifiers.

Copied (with modifications) from go/types.
