I'm looking for a good alternativ to Viper

• urfave/cli

  26 21,565 8.8 Go

  A simple, fast, and fun package for building command line apps in Go (by urfave)

  

  Personally I used https://github.com/urfave/cli for CLI a lot but ended up migrating few project to cobra just because while way to use it was pretty aisine and annoying it ended up better at parsing said CLI (urfave/cli insist on positional arguments which don't work well for some cases)

• kong

  9 1,813 7.6 Go

  Kong is a command-line parser for Go (by alecthomas)

  For all my commandline parsing and config loading needs I use kong. In contrast to Viper and Cobra it has almost no dependencies (while viper and cobra pull in half a jungle).

• kelseyhightower/envconfig

  15 4,884 0.0 Go

  Golang library for managing configuration data from environment variables

  Pretty much all of our services and pkgs use https://github.com/kelseyhightower/envconfig. It’s dead simple, gets out of your way, and is battle tested

• copre

  2 11 0.0 Go

  A small library to load configuration from multiple sources with predefined precedence

  Shameless self-promotion: I encountered the same pain points and put together a small library to tie together multiple configuration sources. As I still really like cobra it is intended to be used with pflags.

• xflags

  1 17 0.0 Go

  Expressive flags for Go (by cavaliergopher)

  

  Self promo: it won’t help with the config file side of things but should elegantly cover the flags and environment variables: https://github.com/cavaliergopher/xflags.

• go-yamlcfg

  1 0 2.6 Go

  For config I ended up making wrapper for YAML parser that did the "pick a config from list list" and "generate default config" features. But my config needs are not that big
