parse helm umbrella charts yaml via yq-CodePudding

There is a need to get a version of the dependency chart based on the name in the Helm umbrella chart structure. How can it be done by using yq tool? Input file example:

apiVersion: v2
name: application1
type: application
version: 0.1.1 
dependencies:
  - name: chart1
    version: v1.13.0
    repository: some-repo
  - name: chart2
    version: v0.11.0
    repository: some-repo

the expected output is the version based on the name of the chart. So I want to be able to pass the chart name(chart1/chart2) and get the version of it:

if name: chart1 output --> v1.13.0

if name: chart2 output --> v0.11.0

With mikefarah/yq, you could use a combination of select and strenv helpers to pass the required version argument as a string and retrieve the corresponding value of version

cname="chart1" yq '.dependencies[]|select(.name == strenv(cname)).version' yaml
