NFPM

NFPM is Not FPM - a simple deb, rpm and apk packager written in Go.

Why

While fpm is great, for me, it is a bummer that it depends on ruby, tar and other softwares.

I wanted something that could be used as a binary and/or as a library and that was really simple.

So I created NFPM: a simpler, 0-dependency, as-little-assumptions-as-possible alternative to fpm.

Usage

Check the documentation at https://nfpm.goreleaser.com

Special thanks 🙏

Thanks to the fpm authors for fpm, which inspires nfpm a lot.

Donate

Donations are very much appreciated! You can donate/sponsor on the main goreleaser opencollective! It's easy and will surely help the developers at least buy some ☕️ or 🍺!

Functions

func ClearPackagers

func ClearPackagers()

ClearPackagers clear all registered packagers, used for testing.

func RegisterPackager

func RegisterPackager(format string, p Packager)

RegisterPackager a new packager for the given format.

func Validate

func Validate(info *Info) (err error)

Validate the given Info and returns an error if it is invalid.

Types

type APK

type APK struct {
	Signature APKSignature `yaml:"signature,omitempty"`
}

type APKSignature

type APKSignature struct {
	PackageSignature `yaml:",inline"`
	// defaults to <maintainer email>.rsa.pub
	KeyName string `yaml:"key_name,omitempty"`
}

type Config

type Config struct {
	Info      `yaml:",inline"`
	Overrides map[string]Overridables `yaml:"overrides,omitempty"`
}

Config contains the top level configuration for packages.

func Parse

func Parse(in io.Reader) (config Config, err error)

Parse decodes YAML data from an io.Reader into a configuration struct.

func ParseFile

func ParseFile(path string) (config Config, err error)

ParseFile decodes YAML data from a file path into a configuration struct.

func (*Config) Get

func (c *Config) Get(format string) (info *Info, err error)

Get returns the Info struct for the given packager format. Overrides for the given format are merged into the final struct.

func (*Config) Validate

func (c *Config) Validate() error

Validate ensures that the config is well typed.

	Rules     string `yaml:"rules,omitempty"`
	Templates string `yaml:"templates,omitempty"`
}

DebScripts is scripts only available on deb packages.

type ErrFieldEmpty

type ErrFieldEmpty struct {
	// contains filtered or unexported fields
}

ErrFieldEmpty happens when some required field is empty.

func (ErrFieldEmpty) Error

func (e ErrFieldEmpty) Error() string

type ErrNoPackager

type ErrNoPackager struct {
	// contains filtered or unexported fields
}

ErrNoPackager happens when no packager is registered for the given format.

func (ErrNoPackager) Error

func (e ErrNoPackager) Error() string

type ErrSigningFailure

type ErrSigningFailure struct {
	Err error
}

ErrSigningFailure is returned whenever something went wrong during the package signing process. The underlying error can be unwrapped and could be crypto-related or something that occurred while adding the signature to the package.
