Render dates, as in neuron

[Terkwood]

Hello!

Just curious whether it would be possible to render the dates associated with neuron-style notes, e.g.

---
date: 2021-09-15T08:43
---

This might only apply to the neuron-style template.

Dates, along with other YAML metadata, can be accessed in the HTML templates. Example,

emanote/default/templates/filters/query-timeline.tpl

Lines 9 to 13 in 31aa931

	<ema:note:metadata>
	<span class="mr-2 text-right text-gray-600">
	<value var="date" />
	</span>
	</ema:note:metadata>

The problem is that it will spit out an error if any note does not have that meta property.

I've detailed one approach to solve this here: snapframework/heist#128 ... basically we extend the template syntax to provide "or else" case (which can be empty text, and it has to be done in the Heist library ... however, none of my issues/PRs to that library so far has received a response from the maintainers.

That's a good idea, I'll take a look. I replicated the simple example from inspirativity successfully, it was only the date snippet which failed

When I put the simple "delectation" example together with the <ema:note:metadata> tag, the latter shows up in HTML but doesn't appear to get transformed into useful output. I can see the "delectation" blurb though.

after-note.tpl

<div>
  <aside class="flex items-center justify-center mt-4 text-xs text-gray-300">
  delectation, enjoyment, appreciation, relish, zest, gusto ... <a href="Satisfaction">satisfaction</a>
  </aside>
  <ema:note:metadata> 
    <span class="mr-2 text-right text-gray-600"> 
      <value var="date" /> 
    </span> 
  </ema:note:metadata> 
</div>

It's ema:metadata (not ema:note:metadata).

[srid]

The ema:note prefix applies to a single result in the query context context of listing of note links (in query results or in tag index). Whereas the ema: prefix is for the current note. I should probably rename these to make it clear enough. Should be done as part of #146 before release

[Terkwood]

It works! Thanks so much for helping me with this!

[Terkwood]

Great, thank you! I will try editing the HTML template

For anyone who finds this discussion later, this is what I wrote in templates/hooks/after-note.tpl in order to display the date:

<ema:metadata>
  <span class="mr-2 text-right text-gray-600">
    <value var="date" />
  </span>
</ema:metadata>

For anyone bothered by the error case, this is a solution that uses our friend JavaScript to remove the date error when there is no date set on the note:

<div class="flex items-center justify-center mt-2">
  <ema:metadata>
    <span id="notedate" class="mr-2 text-right text-gray-600">
      <value var="date" />
    </span>
  </ema:metadata>
  <script>if (notedate.innerText.includes('error')) notedate.innerText = ''</script>
</div>

The styling not great on the example above, please change.

Good tip! Using it here: nixos-asia/website@1e28787

Would be nice to have a template variable for a nicely-formatted date instead of just the raw "date" string as it is in the frontmatter.

To avoid the decoding error, you can also add an empty date to the index.yaml :)
