What’s this?

Typewriter is a package to enable pluggable, type-driven codegen for Go. The envisioned use case is for generics-like functionality. This package forms the underpinning of gen.

Usage is analogous to how codecs work with Go’s image package, or database drivers in the sql package.

import (
    // main package
    “github.com/clipperhouse/typewriter”

    // any number of typewriters 
    _ “github.com/clipperhouse/set”
    _ “github.com/clipperhouse/linkedlist”
)

func main() {
    app, err := typewriter.NewApp(”+gen”)
    if err != nil {
        panic(err)
    }

    app.WriteAll()
}

Individual typewriters register themselves to the “parent” package via their init() functions. Have a look at one of the above typewriters to get an idea.
