TL;DR — Adds a new @hey-api/examples plugin (stub handler, types, and config wired into the plugin registry) and extracts base URL resolution logic from the client-core plugin into a shared getBaseUrl() utility in @hey-api/shared. Also renames the mocker plugin tag to source across both TS and Python packages.

Key changes

• Add @hey-api/examples plugin scaffold — New plugin with config.ts, types.ts, and index.ts registered in the plugin map and type declarations; handler is a no-op stub for now.
• Extract getBaseUrl() into @hey-api/shared — Moves base URL resolution (server lookup, URL validation, path normalization) out of client-core/client.ts into a reusable getBaseUrl() function in packages/shared/src/utils/url.ts.
• Rename mocker tag to source — The PluginTag union replaces 'mocker' with 'source' (and adds 'handler'); PluginMockNames becomes PluginSourceNames in both TS and Python plugin types. @faker-js/faker now uses the 'source' tag.
• Rename orpc.yaml spec files to rpc.yaml — Spec files and all test references updated from orpc.yaml to rpc.yaml; spec titles changed from "oRPC example" to "RPC example".
• Add mockers.yaml test spec — New OpenAPI 3.1.1 spec with example keywords on schemas and responses for testing mocker/example generation.
• Minor style: arrow functions → function declarations — createClientConfigType, createClientOptions, and serverToBaseUrlType converted from const arrow functions to function declarations.

New @hey-api/examples plugin

Before: No plugin for generating example values from OpenAPI specs.
After: @hey-api/examples is registered as a 'source'-tagged plugin with camelCase naming and includeInEntry: false defaults. The handler is a no-op stub — generation logic will follow in a subsequent PR.

The plugin follows the same structural pattern as @faker-js/faker: a config.ts with defaultConfig and defineConfig, a types.ts defining UserConfig, Config, and HeyApiExamplesPlugin, and a barrel index.ts. It's wired into the plugin config map, the Plugins namespace in index.ts, and the @hey-api/shared module augmentation.

Shared getBaseUrl() utility

Before: Base URL resolution lived inline in client-core/client.ts as a private resolveBaseUrlString function with URL parsing and path normalization baked into the caller.
After: getBaseUrl(config, ir) in @hey-api/shared encapsulates server lookup, template-variable filtering, protocol/host validation, and trailing-slash normalization — available to any plugin.

The client-core plugin now calls getBaseUrl(plugin.config.baseUrl ?? true, plugin.context.ir) and uses the new $if chaining API on $.object() to conditionally set baseUrl and throwOnError properties, replacing the imperative if blocks.

What does getBaseUrl filter out?

URLs containing { (server variable templates) are skipped. Bare / is skipped. Absolute URLs must have both protocol and host. Relative paths get trailing slashes trimmed.

Plugin tag taxonomy update

Before: Plugin tags included 'mocker'; type alias was PluginMockNames.
After: 'mocker' replaced by 'source' and 'handler' added to the PluginTag union. PluginMockNames renamed to PluginSourceNames in both TypeScript and Python packages.

This broadens the tag semantics — 'source' now covers any plugin that generates source artifacts (fakers, examples), while 'handler' is a new category for request handler plugins like MSW ('msw' added to the codegen-core module augmentation).

Important

YAML typo in mockers.yaml and a subtle behavioral change in getBaseUrl worth verifying.

Early-stage draft — the scaffolding looks solid. Three items worth addressing before this lands.
