[][src]Crate clap_conf

Clap Conf

Use this library to unify how you get configuration options from

  • The command line arguments
  • Config Files
  • Environmant Variables

Basic Usage

use clap_conf::prelude::*;

let matches = clap_app!(my_app=>
    (@arg filename:-f +takes_value "the input filename")
    //...
).get_matches();

let cfg = with_toml_env(&matches,&["toml/config/locations"]);

//the result must be a String as std::env::var has to return a String not a pointer
let filename =
cfg.grab().arg("filename").conf("input.filename").env("MY_APP_INPUT_FILE").def("default.file");

//if the arguments were supplied this would return something else.
assert_eq!(filename,"default.file".to_string());
