features

env

Enables env feature in clap.

yaml (deprecated, use serde-yaml instead)

Enables to use yaml.

color

Enablse color feature in clap.

(key case settings)

Settings names format for keys and AppSettings.

snake-case-key

snake_case. Enabled by default.

pascal-case-key

PascalCase. Same as variants name in enum at AppSettings.

kebab-case-key

kebab-case.

allow-deprecated

Allow deprecated keys, settings. Enabled by default.

override-args

Override a Arg with DeserializeSeed.

use serde::de::DeserializeSeed;

const CLAP_TOML: &str = r#"
name = "app_clap_serde"
version = "1.0"
author = "aobat"
about = "test-clap-serde"
[args]
apple = { short = "a" }
"#;
let app = Command::new("app").arg(Arg::new("apple").default_value("aaa"));
let wrap = clap_serde::CommandWrap::from(app);
let mut de = toml::Deserializer::new(CLAP_TOML);
let wrap2 = wrap.deserialize(&mut de).unwrap();
let apple = wrap2
    .get_arguments()
    .find(|a| a.get_id() == "apple")
    .unwrap();
assert!(apple.get_short() == Some('a'));
assert!(apple.get_default_values() == ["aaa"]);
