Types ¶
type FileGen ¶
FileGen is a utility for generating/patching golang file ASTs.
func NewFileGen ¶
NewFileGen creates a new FileGen instance from a file AST with the provided package path.
func (*FileGen) AddOrGetImport ¶
AddOrGetImport adds a new import for the provided pkgPath (if needed) and returns the unique import prefix for that path.
func (*FileGen) CreateIdent ¶
CreateIdent creates a new ident that doesn't conflict with reserved symbols, top-level declarations and other defined idents. Idents are unique across the whole file as it is assumed that codegen usually happens on one function per file.
func (*FileGen) PatchFuncDecl ¶
PatchFuncDecl returns a FuncGen instance for the function declaration with the given name or returns nil.
func (*FileGen) TypeExpr ¶
TypeExpr generates an ast.Expr to be used in the context of the file for the provided reflect.Type, adding any needed imports.
func (*FileGen) ValueExpr ¶
ValueExpr generates an ast.Expr to be used in the context of the file for the provided reflect.Value, adding any needed imports. Values with kind Chan, Func, Interface, Uintptr, and UnsafePointer cannot be generated and only pointers to structs can be generated.
