Documentation

Overview

Package parse contains the generic code generation capabilities that power genny.

genny gen "{types}"

gen - generates type specific code (to stdout) from generic code (via stdin)

{types}  - (required) Specific types for each generic type in the source
{types} format:  {generic}={specific}[,another][ {generic2}={specific2}]
Examples:
  Generic=Specific
  Generic1=Specific1 Generic2=Specific2
  Generic1=Specific1,Specific2 Generic2=Specific3,Specific4

Functions

func Generics

func Generics(filename, pkgName string, in io.ReadSeeker, typeSets []map[string]string) ([]byte, error)

Generics parses the source file and generates the bytes replacing the generic types for the keys map with the specific types (its value).

func TypeSet

func TypeSet(arg string) ([]map[string]string, error)

TypeSet turns a type string into a []map[string]string that can be given to parse.Generics for it to do its magic.

Acceptable args are:

Person=man
Person=man Animal=dog
Person=man Animal=dog Animal2=cat
Person=man,woman Animal=dog,cat
Person=man,woman,child Animal=dog,cat Place=london,paris
