how skip a field like #[serde(skip)]

[erickt]

If I’m understanding you correctly, you should be able to define an option field with an option type, with something like this:

    #[derive(FromArgs, PartialEq, Debug)]
    /// Reach new heights.
    struct GoUp<S: FromStr>
    where
        <S as FromStr>::Err: Display,
    {
        /// an optional nickname for the pilot
        #[argh(option)]
        pilot_nickname: Option<S>,
    }
    ```

if nothing is passed in for —pilot-nickname then it will be `None`.

Are there plans to add macros similar to those in like serde #[argh(skip)]

#[derive(Debug, Serialize, Deserialize, Clone, FromArgs, Default)]
#[argh(description = "observer_ward")]
pub struct ObserverWardConfig {
    #[serde(default)]
    #[argh(skip)]
    pub targets: Vec<String>,
    /// the target (required, unless --stdin used)
    #[argh(option, short = 't')]
    pub target: Option<String>,
    /// read target(s) from STDIN
    #[argh(switch)]
    #[serde(skip)]
    pub stdin: bool,
    /// validate the specified yaml file or grep keyword
    #[argh(option)]
    #[serde(skip)]
    pub verify: Option<String>,
    /// read the target from the file
    #[argh(option, short = 'f')]
    #[serde(skip)]
    pub file: Option<String>,
    /// update web fingerprint
    #[argh(switch, short = 'u')]
    #[serde(default)]
    pub update_fingerprint: bool,
    /// export to the csv file or Import form the csv file
    #[argh(option, short = 'c')]
    #[serde(skip)]
    pub csv: Option<String>,
    /// export to the json file or Import form the json file
    #[argh(option, short = 'j')]
    #[serde(skip)]
    pub json: Option<String>,
    /// proxy to use for requests (ex:[http(s)|socks5(h)]://host:port)
    #[argh(option)]
    #[serde(default)]
    pub proxy: Option<String>,
    /// set request timeout.
    #[argh(option, default = "default_timeout()")]
    #[serde(default = "default_timeout")]
    pub timeout: u64,
    /// the 'plugins' directory is used when the parameter is the default
    #[argh(option)]
    #[serde(default)]
    pub plugins: Option<String>,
    /// update nuclei plugins
    #[argh(switch)]
    #[serde(default)]
    pub update_plugins: bool,
    /// an optional nickname for the pilot
    #[argh(switch)]
    #[serde(skip)]
    pub update_self: bool,
    /// number of concurrent threads.
    #[argh(option, default = "default_thread()")]
    #[serde(default = "default_thread")]
    pub thread: u32,
    /// send results to webhook server (ex:https://host:port/webhook)
    #[argh(option)]
    #[serde(default)]
    pub webhook: Option<String>,
    /// using nmap fingerprint identification service (slow)
    #[argh(switch)]
    #[serde(default)]
    pub service: bool,
    /// start a web API service (ex:127.0.0.1:8080)
    #[argh(option, short = 's')]
    #[serde(skip)]
    pub api_server: Option<String>,
    /// api Bearer authentication
    #[argh(option, default = "default_token()")]
    #[serde(skip)]
    pub token: String,
    /// api background service
    #[argh(switch)]
    #[serde(skip)]
    pub daemon: bool,
    /// an optional nickname for the pilot
    #[argh(switch)]
    #[serde(skip)]
    pub silent: bool,
    /// filter mode,Display only the fingerprint that is not empty
    #[argh(switch)]
    #[serde(skip)]
    pub filter: bool,
}

@cn-kali-team Just submitted a PR that implements exactly this (#[argh(skip)] or #[argh(skip, default = "...")]) 🙂
