[![Go Reference](https://pkg.go.dev/badge/github.com/ancientlore/flagcfg.svg)](https://pkg.go.dev/github.com/ancientlore/flagcfg)

The flagcfg package populates flags from a TOML config file.

Each flag is assumed to have an optional top-level value

in the config file, having the same name. However, if a

flag contains a dash or a period, those are converted to

underscores.

Flags that have aready been assigned are not overwritten.

This package can be used together with github.com/facebookgo/flagenv

to load flags from a config file, environment variable, or command-line.

Example:

	// Parse flags from command-line

	flag.Parse()

	// Parser flags from config

	flagcfg.AddDefaults()

	// or use flagcfg.AddDefaultFiles("MYAPP_CONFIG", "myapp.config")

	flagcfg.Parse()

	// Parse flags from environment (using github.com/facebookgo/flagenv)

	flagenv.Prefix = "MYPREFIX_"

	flagenv.Parse()
