meta.title and meta.description only renders first character

[martinbira]

Description

The content in <title></title> and <description></description> derived from the page meta title and description only consist of the first character for the page meta value.

Expected behavior

<title></title> should consist of full content from the page meta title
<description></description> should consist of full content from the page meta description

Actual behavior

<title></title> consist of only the first character from the page meta title
<description></description> consist of only the first character from the page meta description

Steps to reproduce the bug

1. In page.md set the following meta data:

---
title: Page title
description: Page description
---

2. Verify that mkdocs builds page.
3. Check page source for <title>P</title> and <description>P</description>

Package versions

• Python: 3.6.1
• MkDocs: 0.17.1
• Material: 2.01

System information

• OS: Windows 10

I could reproduce this issue but it's easily fixed by using the following:

---
page.title: Page title
page.description: Page description
---

I got those variable names from the MkDocs 0.17.0 Release Notes:

An update from me. I realised that using the above does correctly populates the title and description - but it also adds the title and description within the HTML of the page. Looks like a bug.

Using the following works though:

---
page_title: Page title
page_description: Page description
---

Fixed in #554, release will follow today.

The same is true for author metadata. For example,

---
author: John Doe
---

yields in the HTML head

<meta name="author" content="J">

and the same workaround succeeds:

---
page.author: John Doe
---

yields

<meta name="author" content="John Doe">

Same fix as in #554 - I can't remember why I put the first modifier on it, maybe the format was different some time ago. Feel free to open a new issue for this so it doesn’t get forgotten.
