# Array to Map
|
|
|
|
Use this operator to convert an array to..a map. Skips over null values.
|
|
|
|
Behind the scenes, this is implemented using reduce:
|
|
|
|
```
|
|
(.[] | select(. != null) ) as $i ireduce({}; .[$i | key] = $i)
|
|
```
|
|
|
|
## Simple example
|
|
Given a sample.yml file of:
|
|
```yaml
|
|
cool:
|
|
- null
|
|
- null
|
|
- hello
|
|
```
|
|
then
|
|
```bash
|
|
yq '.cool |= array_to_map' sample.yml
|
|
```
|
|
will output
|
|
```yaml
|
|
cool:
|
|
2: hello
|
|
```
