Summary

Currently Argo does not allow white space in templating, rendering of {{workflow.parameters.variable}} does correctly work, however {{ workflow.parameters.variable }} doesn't render the variable. Also argo lint did not issue any warning or error.

Use Cases

I often find it more readable when you can add whitespace to separate markers like {{ and }} from variable names.

Good idea. Would you like to investigate how to fix this?

I'm not that proficient in Go, but looks like in function Replace this https://github.com/argoproj/argo/blob/8facaceeb3515d804c3fd276b1802dbd6cf773e8/workflow/common/util.go#L375
could probably be replaced with:

  replacement, ok := replaceMap[strings.TrimSpace(tag)]
