tp.frontmatter does not respect "quotation marks" --> "

[mariusgerome]

Describe the bug
I build a template that should update my old metadata for a file.

Example:
I have a file with the property tag -> category-example: "[[link]]"
the quotation marks don't get recognized with the <% tp.frontmatter["category-example"] %> command

Expected behavior
category-example: "[[link]]"
but what I get instead is: category-example: [[link]]

You can wrap it in quotes like this as a workaround.

"<% tp.frontmatter["category-example"] %>"

[mariusgerome]

You're right,
but then "list-properties" would turn into something like this:
category-example: "[[link 1]], [[link 2]], [[link 3]]"

instead of:

category-example:
- "[[link 1]]"
- "[[link 2]]"
- "[[link 3]]"

:/ :D

You're right! For list properties, you can do this to wrap each entry in quotes.

<% tp.frontmatter["category-example"].map(prop => `"${prop}"`) %>

Hey Zachatoo,

output: category-example: "item 1","item 2","item 3"
… which is "invalid frontmatter". As long as it's only one item; it works. Like: category-example: "item 1"
But with multiple items in a row like that, it's invalid.

Do you have a similar epic-code hack, that puts all of those list-values in quotation marks AND puts them on a new line?

from:

category-example: 
  - item 1
  - item 2
  - item 3
  - item 4

to:

well… the exact same thing…

… but written with a tp.frontmatter extraction template.

BTW are you a dev of the templater plugin, or just a hyper active github user?

Right, needs to be wrapped in [] to be valid

[<% tp.frontmatter["category-example"].map(prop => `"${prop}"`) %>]

Could do something like this

<% tp.frontmatter["category-example"].map(prop => `\n  - "${prop}"`) %>

[Zachatoo]

I'm the current maintainer of Templater, so yes I add features and fix bugs as I have time

[mariusgerome]

Could do something like this

<% tp.frontmatter["category-example"].map(prop => `\n  - "${prop}"`) %>

This seems to work, I got a correct output one time (only leaving , at the end of one line, but thats fine.
But I cant replicate this, something is broken with my obsidian I think. I get this Template parsing error, aborting aaaallll the time. So weird that I cant run the same exact thing twice without having to restarting obsidian :D … anyway, thats on me.

Thank you Zachatoo!
Maybe this finds a way into the docs, and as an extension to the current tp.frontmatter list.

May be a user script, though we can continue that conversation over here

Good idea, I'll add a few more examples

[Zachatoo]

Added an example to the docs, now doesn't have the , anymore

<% tp.frontmatter.categories.map(prop => `  - "${prop}"`).join("\n") %>
