Custom Commands for server-url-templating-api-single-base-url
Overview
The server-url-templating-api-single-base-url 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/server-url-templating-api-single-base-url/custom.rs ← Your command handlers (protected by .fernignore) cli/server-url-templating-api-single-base-url/sdk.rs ← Generated bridge: client() + block_on() cli/server-url-templating-api-single-base-url/main.rs ← Generated entrypoint (calls custom::register) server-url-templating-api-single-base-url-sdk/ ← Co-generated typed SDK crate server-url-templating-api-single-base-url-types/ ← Co-generated typed model crate
Adding a Custom Command
1. Edit cli/server-url-templating-api-single-base-url/custom.rs
This file is protected by .fernignore — fern generate will never overwrite it. Register commands in the register() function:
use server_url_templating_api_single_base_url_sdk::api::*;
pub fn register(app: CliApp) -> CliApp {
let app = app.command(
clap::Command::new("my-command")
.about("Description of your command")
.arg(clap::Arg::new("id").required(true)),
|matches, ctx| {
let id = matches.get_one::<String>("id").unwrap();
let client = super::sdk::client(ctx);
let result = super::sdk::block_on(
client.resource.get(id),
)?;
println!("{}", serde_json::to_string_pretty(&result).unwrap());
Ok(())
},
);
app
}
2. Available SDK Clients
The super::sdk::client(ctx) call returns a server_url_templating_api_single_base_url_sdk::api::Client with the following sub-clients:
(Sub-clients are derived from the API spec at generation time.)
3. Key Patterns
Get the SDK client (execution-sharing, fully authenticated):
let client = super::sdk::client(ctx);
Run an async SDK call from a sync handler:
let result = super::sdk::block_on(
client.some_resource.some_method(args),
)?;
Use typed models for request/response serialization:
use server_url_templating_api_single_base_url_sdk::api::*;
Regeneration Safety
| File | Regenerated? | Notes | |------|-------------|-------| | cli/server-url-templating-api-single-base-url/custom.rs | No | Protected by .fernignore | | cli/server-url-templating-api-single-base-url/sdk.rs | Yes | Bridges AppContext → SDK client | | cli/server-url-templating-api-single-base-url/main.rs | Yes | Calls custom::register(app) | | server-url-templating-api-single-base-url-sdk/ | Yes | Co-generated typed SDK crate | | server-url-templating-api-single-base-url-types/ | Yes | Co-generated typed models |
After running fern generate, your custom.rs is preserved. All generated code (SDK, types, glue, main.rs) is updated to match the latest API spec. If the SDK surface changes (renamed methods, new sub-clients), update your custom.rs to match.
