Switch Case Codegen

Overview:

Tool for generating switch cases for enums.

Install:

go install github.com/Ferrany1/switch-case-codegen/cmd/switch-case-codegen

Usage:

Cli:

switch-case-codegen enum [flags]

Flags:
-p, --file_path string       path to file with enums
-h, --help                   help for enum
-i, --include_exported       include non exported enums (default:false) (default true)
-o, --output string          output file (default:stdout)
-n, --package_name string    generated import package name (default:empty)
-t, --template_type string   template to generate. options: raw|function (default:raw) (default "raw")
--types strings          types to generate (default:all)

Global Flags:
-v, --verbose   verbose error output

Go file:

//go:generate switch-case-codegen enum -p ./enums.go -t function -n test_package

Example:

Function:

enum.go:

//go:generate switch-case-codegen enum -p ./enum.go -t function -n test_package --types TestType2

type TestType1 string

const (
	TestType1Value1 TestType1 = "1"
	TestType1Value2 TestType1 = "2"
	TestValue1      string    = "3"
	TestValue2      int       = 4
)

type TestType2 int

const (
	TestType2Value1 TestType2 = iota
	TestType2Value2
	TestType2Value3
	TestType2Value4
	testType2Value5
)

output:

func blob(input test_package.TestType2) {
	switch test_package.input { 
	case test_package.TestType2Value1:
		// TODO: add case expression
	case test_package.TestType2Value2:
		// TODO: add case expression
	case test_package.TestType2Value3:
		// TODO: add case expression
	case test_package.TestType2Value4:
		// TODO: add case expression
	case test_package.testType2Value5:
		// TODO: add case expression
	}
}

Raw:

enum.go:

//go:generate switch-case-codegen enum -p ./enum.go -n test_package --types TestType2

type TestType1 string

const (
	TestType1Value1 TestType1 = "1"
	TestType1Value2 TestType1 = "2"
	TestValue1      string    = "3"
	TestValue2      int       = 4
)

type TestType2 int

const (
	TestType2Value1 TestType2 = iota
	TestType2Value2
	TestType2Value3
	TestType2Value4
	testType2Value5
)

output:

switch test_package.input {
case test_package.TestType2Value1:
// TODO: add case expression
case test_package.TestType2Value2:
// TODO: add case expression
case test_package.TestType2Value3:
// TODO: add case expression
case test_package.TestType2Value4:
// TODO: add case expression
case test_package.testType2Value5:
// TODO: add case expression
}
