How to persist yaml frontmatter?

[tophee]

Is there a way of protecting YAML frontmatter when a literature note is overwritten upon re-import?

I tried

---
{% persist "yaml" %}
aliases: ["@{{citekey}}"{% if shortTitle %}, {{shortTitle | lower}}{% endif %} ]
{% endpersist %}
---

but it breaks the yaml-header (aliases no longer work for a note because of the %% begin yaml %% and %% end yaml %%.

(And even if those comments weren't a problem, it would still not work, because a new alias line would be added to the header and once there is more than one alias line, they all stop working. But that is a different issue.

For now I would just like to manually add aliases and prevent the template from overwriting them upon import. Is there a way?

Same issue as #60

@Trikzon suggested using dataview inline fields for adding metadata, but its not the same as using Obsidian's native support for aliases/tags.

{% persist "tags" %}
tags:: Incomplete
{% endpersist %}

Found this trick to work to rebuild frontmatter from Templater instead of this plugin: https://forum.obsidian.md/t/frontmatter-in-templater-seeking-solutions-for-3-use-cases/67670/5

Add this snippet in your file (this adapted snippet from my Vault has not been tested, let me know if it doesn't work for you):

<%* 
// Source : https://forum.obsidian.md/t/frontmatter-in-templater-seeking-solutions-for-3-use-cases/67670/5

// The reason for the timeout is to wait until after the new note exists in your vault.
setTimeout(() => {
  // Get the path to the new file
  const newFile = tp.file.find_tfile(tp.file.path(true))
  // Process the frontmatter
  app.fileManager.processFrontMatter(newFile, (frontmatter) => {
      // Add a new field
      frontmatter['Related'] = '[[Source bibliographique]]' // Related notes property
      frontmatter['citekey'] = '{{citekey}}' // Normal property
      frontmatter['alias'] = ['{{title}}', '{{citekey}}'] // List property
  })
}, 300)
%>
