Enums are not a first class citizen in Go, and are often implemented as a set of constants. This tool aims to make it easier to create enums in Go and has various options for generating the enum in different styles and languages, which is especially useful when working with a codebase with manually written enums that already have a certain style.
Available Styles:
camelCase: thisIsCamelCasepascalCase: ThisIsPascalCasesnakeCase: this_is_snake_casekebabCase: this-is-kebab-caseupperCase: THISISUPPERCASEscreamingKebabCaseTHIS-IS-SCREAMING-KEBAB-CASEscreamingSnakeCaseTHIS_IS_SCREAMING_SNAKE_CASE
Either use it from the command line:
genumer --name="MyEnum"" --values="firstValue,secondValue" --dest="cmd/"
which will generate a file called myenum.go in the cmd/ directory
or use it as a go generate directive:
//go:generate genumer --name "enumStyle" --values "camelCase,pascalCasing,screamingSnakeCase" --dest "cmd/test/"
--createDir
which will generate a file called enumstyle.go in the cmd/test directory, creating the directories if they do not exist
genumer [flags]
Examples:
genumer --name=myEnum --values="firstValue,secondValue" --dest=generated/
Flags:
--createDir Create the destination directory/directories if they do not exist
-d, --dest string Destination of generated go enum file
-h, --help help for genumer
-n, --name string Name of the enum in camelCase, e.g. "myEnum"
-p, --package string Package of generated go enum file. If not set, the destination will be used to deduct package name
--private Make the generated enum private
-s, --style string Style of the generated go enum names: camelCase, pascalCase, upperCase, kebabCase, screamingKebabCase, snakeCase, screamingSnakeCase (default "camelCase")
-v, --values string Target enum values in camelCase, e.g. "firstValue,thenSecond,theVeryLastValue"
