description	How to author custom commands for the nullable-request-body CLI using the co-generated SDK.

Custom Commands for nullable-request-body

Overview

The nullable-request-body CLI supports user-authored custom commands that are compiled into the binary alongside the auto-generated API commands. Custom commands get a fully-wired SDK client that inherits the CLI's auth, retries, TLS, base URL, and global headers — zero configuration required.

Architecture

cli/nullable-request-body/custom.rs    ← Your command handlers (protected by .fernignore)
cli/nullable-request-body/sdk.rs       ← Generated bridge: client() + block_on()
cli/nullable-request-body/main.rs      ← Generated entrypoint (calls custom::register)
nullable-request-body-sdk/             ← Co-generated typed SDK crate
nullable-request-body-types/           ← Co-generated typed model crate

Adding a Custom Command

1. Edit cli/nullable-request-body/custom.rs

This file is protected by .fernignore — fern generate will never overwrite it. Register commands in the register() function:

use nullable_request_body_sdk::api::*;

pub fn register(app: CliApp) -> CliApp {
    let app = app.command(
        clap::Command::new("test-method-name")
            .about("Post Nullable Request Body")
            .(clap::Arg::().())
        ,
        |matches, ctx| {
              = matches.get_one::<>().();
              = super::sdk::(ctx);
              = super::sdk::(
                client.test_group.(path_param),
            )?;
            (, serde_json::(&result).());
            (())
        },
    );
    app
}
