astfmt
Package astfmt implements ast.Node formatting with fmt-like API.
Installation
go get github.com/go-toolsmith/astfmt
Example
package main
import (
"go/token"
"os"
"github.com/go-toolsmith/astfmt"
"github.com/go-toolsmith/strparse"
)
func Example() {
x := strparse.Expr(`foo(bar(baz(1+2)))`)
// astfmt functions add %s support for ast.Node arguments.
astfmt.Println(x) // => foo(bar(baz(1 + 2)))
astfmt.Fprintf(os.Stdout, "node=%s\n", x) // => node=foo(bar(baz(1 + 2)))
// Can use specific file set with printer.
fset := token.NewFileSet() // Suppose this fset is used when parsing
pp := astfmt.NewPrinter(fset)
pp.Println(x) // => foo(bar(baz(1 + 2)))
}
