Code lines are struckthrough and red

[JoelMTaylor]

Type: Bug

When I opened my workspace, I noticed that some or all (depending on the page) of the text is red and struckthrough (strikethrough appearance). I did nothing.

I disabled all extensions and restarted the window, and it is still the same. I assume this was an update, but I cannot see why based on the update docs.

I am writing documents using Markdown. This is for a docs site that uses Retype.

# Class Tools

{{ include "under-construction" }}

## Introduction



## Class Placemat

The **Class Placemat** summarises key class data for the teacher's review.

 1. Select the Year Level, Subject and Class, then click **Find**.
 2. Students are grouped based on their previous end of semester result in the subject (into A's, B's, etc.).\

Seems to be due to use of --- - which is used for page metadata. Without these, it does not occur.

@RedCMD, I have updated the original post with the screenshots and code.

It seems that the theme - the colours and formatting of the code - has changed, too. I assume this is related.

[RedCMD]

caused by #219833

the page metadata is written in YAML

YAML states anything after the {{ include "joel-taylor" }} is invalid (because it is missing an ending :)
however that FrontMatter variable is preprocessed into valid YAML when the markdown is loaded

I've removed the strikethrough
and filed a bug report to microsoft/vscode-markdown-tm-grammar#164 for YAML escaping the ending ---
I'll change how an invalid {{ ... }} is interrupted

[RedCMD]

Will still need to wait for the fix at microsoft/vscode-markdown-tm-grammar#162

[mjbvz]

Fixed by picking up the latest grammar. Thanks @RedCMD!
