# astfmt
|
|
|
|
Package astfmt implements ast.Node formatting with fmt-like API.
|
|
|
|
## Installation
|
|
|
|
```bash
|
|
go get github.com/go-toolsmith/astfmt
|
|
```
|
|
|
|
## Example
|
|
|
|
```go
|
|
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)))
|
|
}
|
