gogen

A simplification of Go's go/ast package that allows for some interesting code generation. Currently very rough.

Examples

Hello World

package main

import (
	"os"
	. "github.com/garslo/gogen"
)

func main() {
	pkg := Package{Name: "main"}
	pkg.Declare(Import{"fmt"})
	pkg.Declare(Function{
		Name: "main",
		Body: []Statement{
			CallFunction{
				Func:   Dotted{Var{"fmt"}, "Println"},
				Params: []Expression{Var{`"Hello World!"`}},
			},
		},
	})
	pkg.WriteTo(os.Stdout)
}

Output:

package main

import "fmt"

func main() {
	fmt.Println("Hello World!")
}
