gengen

Little go:generate tool for quick "generics" (using templates).

Usage

Usage of gengen:
  -d string
        Directory to parse files from
  -o string
        Output filename
  -t string
        Template to render

Example go generate directive (taken from gomaild2):

//go:generate gengen -d ./commands/ -t process.go.tmpl -o process.go

gengen parses a directory (-d) for Go code, then renders your template (-t) exposing the parsed data as .Packages (map[name string]*ast.Package). This helps reduce "pseudo-generic" boilerplate code, such as monolithic switch statements (see gomaild2's SMTP command processor).
