Package conf provides support for using environmental variables and command line arguments for configuration. It is compatible with the GNU extensions to the POSIX recommendations for command-line options. See http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html There are no hard bindings for this package. This package takes a struct value and parses it for both the environment and flags. It supports several tags to customize the flag options. The field name and any parent struct name will be used for the long form of the command name unless the name is overridden. As an example, this config struct: Would produce the following usage output: Usage: conf.test [options] [arguments] OPTIONS The API is a single call to Parse Additionally, if the config struct has a field of the slice type conf.Args then it will be populated with any remaining arguments from the command line after flags have been processed. For example a program with a config struct like this: If that program is executed from the command line like this: Then the cfg.Args field will contain the string values ["serve", "http"]. The Args type has a method Num for convenient access to these arguments such as this: You can add a version with a description by adding the Version type to your config type Then you can set these values at run time for display.
