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

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.
