conditional go templating and looping

[dberardo-com]

i am used to jinja if/else blocks and for loops, is it currently possible to achieve something like this in argo string templates?

basically i want to APPLY a k8s manifest in an argo workflow template and the spect part of the manifest depend on an input parameter. can i use something like this from jinja ?

{% if input.parameters.myVar == "test" %}
spec:
 a: {{ input.parameters.myVar }}
{% else %}
spec:
 b: {{ input.parameters.myVar }}
{% endif %}

the same is true for for loops (i guess it is called range in go template?
