# Objective
This idea came up in the context of a hypothetical "text sections as
entities" where text sections are children of a text bundle.
```rust
commands
.spawn(TextBundle::default())
.with_children(|parent} {
parent.spawn(TextSection::from("Hello"));
});
```
This is a bit cumbersome (but powerful and probably the way things are
headed). [`bsn!`](https://github.com/bevyengine/bevy/discussions/14437)
will eventually make this nicer, but in the mean time, this might
improve ergonomics for the common case where there is only one
`TextSection`.
## Solution
Add a `with_child` method to the `BuildChildren` trait that spawns a
single bundle and adds it as a child to the entity.
```rust
commands
.spawn(TextBundle::default())
.with_child(TextSection::from("Hello"));
```
## Testing
I added some tests, and modified the `button` example to use the new
method.
If any potential co-authors want to improve the tests, that would be
great.
## Alternatives
- Some sort of macro. See
https://github.com/tigregalis/bevy_spans_ent/blob/main/examples/macro.rs#L20.
I don't love this, personally, and it would probably be obsoleted by
`bsn!`.
- Wait for `bsn!`
- Add `with_children_batch` that takes an `Into<Iterator>` of bundles.
```rust
with_children_batch(vec![TextSection::from("Hello")])
```
This is maybe not as useful as it sounds -- it only works with
homogeneous bundles, so no marker components or styles.
- If this doesn't seem valuable, doing nothing is cool with me.
