|
The `utils.mergeOptions()` function merges the user-provided options with the
|
||
|
|
options from the pattern configuration.
|
||
|
|
|
||
|
|
## Signature
|
||
|
|
|
||
|
|
```js
|
||
|
|
float deg2rad(object settings, object optionsConfig)
|
||
|
|
```
|
||
|
|
|
||
|
|
## Notes
|
||
|
|
|
||
|
|
Typically the only options that are passed as part of settings to the pattern
|
||
|
|
are those that differ from the defaults. This means that if you want to check
|
||
|
|
an option outside a draft method, you need to check whether the option is set,
|
||
|
|
and if it's not get the default value from the pattern config. Furthermore,
|
||
|
|
where the default is stored and whether or not it should be further transformed
|
||
|
|
depends on the option type.
|
||
|
|
|
||
|
|
This method exists to facilitate this. You pass it the user-provided settings,
|
||
|
|
and the pattern config options key, and it will return an object where all
|
||
|
|
options are populated with the user-provided values, or their defaults if the
|
||
|
|
user did not provide any input.
