# gogen

|
A simplification of Go's `go/ast` package that allows for some
|
||
|
|
interesting code generation. Currently very rough.
|
||
|
|
|
||
|
|
# Examples
|
||
|
|
|
||
|
|
## Hello World
|
||
|
|
```go
|
||
|
|
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:
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import "fmt"
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
fmt.Println("Hello World!")
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
