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)))
}
