Bad date error reporting for frontmatters is inscrutable.

[artemislena]

Given the following file as a post or page:

---
layout: default.liquid

title: Test
permalink: /2020/07
published_date: 2020-07-24
---
#Test!

This is a test. Lorem Ipsum Dolor Sit Amet.

cobalt build returns
Error: build command failed Info: caused by Failed to parse posts/2020/07/testpost.md Info: caused by premature end of input at line 1 column 7. Strangely, when copying the default post-1.md into said file and changing it so it is basically the same, it doesn't show this behaviour.

With --log-level=debug, I get this:

I think the debug output's newlines got lost.
(granted, I don't think there is something in there to help)

[epage]

What version of cobalt

[artemislena]

--version shows Cobalt 0.16.0. The latest version from Github Releases. I think the newlines got lost due to how (Github) Markdown works… Anyway, running with --trace shows that the file is opened only after all the debug output, so it is indeed not too helpful here.

[epage]

Wow, this is some terrible error reporting.

Cobalt expects full date/times to be passed in for published_date.

For example

published_date: "2020-07-24 07:05:20 +0100"

An easy way of working with this is to use cobalt new to create documents and then cobalt publish to get them out of draft-state.

Seems like it indeed is. Thanks for the hint, that fix seems to work.
