Overview ¶

This package implements the BeeHive compiler that automatically generates Map functions by inspecting event handlers of applications. This compiler is simplistic and supports a few, common scenarios.

Functions ¶

func GenerateMap ¶

func GenerateMap(w io.Writer, handlers []*Handler) error

Generates map function for the given handlers into the writer. Handlers must be all of the same package.

Types ¶

type Handler ¶

type Handler struct {
	Type    ast.Expr          // Type of the handler.
	Rcv     *ast.FuncDecl     // Rcv function of the handler. Cannot be nil.
	Map     *ast.FuncDecl     // Map function of the handler. Can be nil.
	Imports map[string]string // Packages that must be imported for mapping.
	Package string            // Package name of this handler.
}

Represents a message handler.

func HandlersInDir ¶

func HandlersInDir(fset *token.FileSet, path string) ([]*Handler, error)

func HandlersInPackage ¶

func HandlersInPackage(pkg *ast.Package) ([]*Handler, error)

Finds all the event handlers declared in package.
