Dynamic expiryDate in archetype

support
2

You are currently processing the archetype so you cannot access the properties you set before (guess implementation and performance considerations.)

but you may store stuff in variables

---
{{- $mydate := "2024-03-25" }}
title: '{{ replace .File.ContentBaseName "-" " " | title }}'
date: "{{- $mydate -}}"
expiryDate: '{{- (time.AsTime $mydate).AddDate 0 0 30 | time.Format "2006-01-02" -}}'
---

which produces with hugo new content test.md

---
title: 'Test'
date: "2024-03-25"
expiryDate: '2024-04-24'
---
