Constants

General printing is controlled with these Config.Mode flags.

const (
    RawFormat uint = 1 << iota // do not use a tabwriter; if set, UseSpaces is ignored
    TabIndent                  // use tabs for indentation independent of UseSpaces
    UseSpaces                  // use spaces instead of tabs for alignment
)

func Fprint

func Fprint(output io.Writer, fset *token.FileSet, node interface{}) os.Error

Fprint "pretty-prints" an AST node to output. It calls Config.Fprint with default settings.

type Config

A Config node controls the output of Fprint.

type Config struct {
    Mode     uint // default: 0
    Tabwidth int  // default: 8
}

func (*Config) Fprint

func (cfg *Config) Fprint(output io.Writer, fset *token.FileSet, node interface{}) (int, os.Error)

Fprint "pretty-prints" an AST node to output and returns the number of bytes written and an error (if any) for a given configuration cfg. Position information is interpreted relative to the file set fset. The node type must be *ast.File, or assignment-compatible to ast.Expr, ast.Decl, ast.Spec, or ast.Stmt.
