Gen

Gen is a package that provides code generation using functional compoistion of functions, where each is built around the concept of composable io.WriterTo. Each writer wraps the passed content of the next writer creating flexible structures for generating code or text easily.

Code Generation Structures

This package provides sets of structures which define specific code structures and are used to built a programmatically combination that define the expected code to be produced. It also provides a functional composition style functions that provide a cleaner and more descriptive approach to how these blocks are combined.

The code gen is heavily geared towards the use of text/template but also ensures to be flexible to provide non-template based structures that work as well.

Example

• Generate a struct with moz

import "github.com/influx6/moz/gen"

floppy := gen.Struct(
		gen.Name("Floppy"),
		gen.Commentary(
			gen.Text("Floppy provides a basic function."),
			gen.Text("Demonstration of using floppy API."),
		),
		gen.Annotations(
			"Flipo",
			"API",
		),
		gen.Field(
			gen.Name("Name"),
			gen.Type("string"),
			gen.Tag("json", "name"),
		),
)

var source bytes.Buffer

floppy.WriteTo(&source) /*
// Floppy provides a basic function.
//
// Demonstration of using floppy API.
//
//
//@Flipo
//@API
type Floppy struct {

    Name string `json:"name"`

}
*/

• Generate a function with moz

import "github.com/influx6/moz/gen"

main := gen.Function(
    gen.Name("main"),
    gen.Constructor(
        gen.FieldType(
            gen.Name("v"),
            gen.Type("int"),
        ),
        gen.FieldType(
            gen.Name("m"),
            gen.Type("string"),
        ),
    ),
    gen.Returns(),
    gen.SourceText(`	fmt.Printf("Welcome to Lola Land");`, nil),
)

var source bytes.Buffer

main.WriteTo(&source) /*
func main(v int, m string) {
	fmt.Printf("Welcome to Lola Land");
}
*/
