`SimpleComponent`: a lightweight named-span component.

`SimpleComponent` accepts arbitrary keyword arguments (strings, [`CBlock`](../../core/base#class-cblock)s, or
[`Component`](../../core/base#class-component)s) and renders them as a JSON object keyed by the argument names. It is
the go-to component type for ad-hoc prompts that do not require a dedicated
[`Component`](../../core/base#class-component) subclass or a Jinja2 template.

## Classes

<div className="w-full h-px bg-gray-200 dark:bg-gray-700 my-4" />

### <span className="ml-2 inline-flex items-center rounded-full px-2 py-1 text-[0.7rem] font-bold tracking-wide bg-[#4ADE8033]/20 text-[#15803D]">CLASS</span> `SimpleComponent` <sup><a href="https://github.com/generative-computing/mellea/blob/v0.6.0/mellea/stdlib/components/simple.py#L14" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

A Component that is make up of named spans.

<div className="h-8" />

**Methods:**

<div className="w-full h-px bg-gray-200 dark:bg-gray-700 my-4" />

#### <span className="ml-2 inline-flex items-center rounded-full px-2 py-1 text-[0.7rem] font-bold tracking-wide bg-[#3064E3]/20 text-[#1D4ED8]">FUNC</span> `parts` <sup><a href="https://github.com/generative-computing/mellea/blob/v0.6.0/mellea/stdlib/components/simple.py#L25" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python theme={null}
parts(self) -> list[Component | CBlock]
```

Returns the values of the kwargs.

**Returns:**

* List of component values passed as keyword arguments.

<div className="w-full h-px bg-gray-200 dark:bg-gray-700 my-4" />

#### <span className="ml-2 inline-flex items-center rounded-full px-2 py-1 text-[0.7rem] font-bold tracking-wide bg-[#3064E3]/20 text-[#1D4ED8]">FUNC</span> `make_simple_string` <sup><a href="https://github.com/generative-computing/mellea/blob/v0.6.0/mellea/stdlib/components/simple.py#L43" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python theme={null}
make_simple_string(kwargs: dict[str, Any]) -> str
```

Render keyword arguments as `<|key|>value</|key|>` tagged strings.

**Args:**

* `kwargs`: Mapping of span names to their [`CBlock`](../../core/base#class-cblock) or
  [`Component`](../../core/base#class-component) values.

**Returns:**

* Newline-joined tagged representation of all keyword arguments.

<div className="w-full h-px bg-gray-200 dark:bg-gray-700 my-4" />

#### <span className="ml-2 inline-flex items-center rounded-full px-2 py-1 text-[0.7rem] font-bold tracking-wide bg-[#3064E3]/20 text-[#1D4ED8]">FUNC</span> `make_json_string` <sup><a href="https://github.com/generative-computing/mellea/blob/v0.6.0/mellea/stdlib/components/simple.py#L58" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python theme={null}
make_json_string(kwargs: dict[str, Any]) -> str
```

Serialize keyword arguments to a JSON string.

Each value is converted to its string representation: [`CBlock`](../../core/base#class-cblock) and
[`ModelOutputThunk`](../../core/base#class-modeloutputthunk) values use their `.value` attribute, while
[`Component`](../../core/base#class-component) values use `format_for_llm()`.

**Args:**

* `kwargs`: Mapping of span names to [`CBlock`](../../core/base#class-cblock), [`Component`](../../core/base#class-component),
  or [`ModelOutputThunk`](../../core/base#class-modeloutputthunk) values.

**Returns:**

* JSON-encoded representation of the keyword arguments.

<div className="w-full h-px bg-gray-200 dark:bg-gray-700 my-4" />

#### <span className="ml-2 inline-flex items-center rounded-full px-2 py-1 text-[0.7rem] font-bold tracking-wide bg-[#3064E3]/20 text-[#1D4ED8]">FUNC</span> `format_for_llm` <sup><a href="https://github.com/generative-computing/mellea/blob/v0.6.0/mellea/stdlib/components/simple.py#L83" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python theme={null}
format_for_llm(self) -> str
```

Format this component as a JSON string representation for the language model.

Delegates to `make_json_string` using the stored keyword arguments.

**Returns:**

* JSON-encoded string of all named spans in this component.

<div className="w-full h-px bg-gray-200 dark:bg-gray-700 my-4" />
