NewTransformer returns a transformer based on the specified template, a single-file package containing "before" and "after" functions as described in the package documentation. tmplInfo is the type information for tmplFile.

func (*Transformer) Transform

func (tr *Transformer) Transform(info *types.Info, pkg *types.Package, file *ast.File) int

It mutates the AST in place (the identity of the root node is unchanged), and may add nodes for which no type information is available in info.
