Crate clap_conf[][src]

Expand description

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());

Modules

Macros

Build App, Args, SubCommands and Groups with Usage-string like input but without the associated parsing runtime cost.

Allows you to pull the version from your Cargo.toml at compile time as MAJOR.MINOR.PATCH_PKGVERSION_PRE

Structs

Used to get information about the arguments that were supplied to the program at runtime by the user. New instances of this struct are obtained by using the App::get_matches family of methods.

An iterator for getting multiple values out of an argument via the ArgMatches::values_of method.
