Vscode-markdown: "Print to HTML" can be called on non-Markdown editor and cause error

Created on 11 Jun 2018 · 22Comments · Source: yzhang-gh/vscode-markdown

What is the problem?

Print current document to HTML fails and gives error.

How can I reproduce it?

Make a Markdown file and try to print it to HTML

Is there any error message in the console? (from menubar -> Help -> Toggle Developer Tools)

Error: Running the contributed command:'markdown.extension.printToHtml' failed.

This error message seems not to tell us why it failed. Could you please download the latest CI build and try to print again? (You can find the download link at the end of README.md)

Sure, what exactly do I do with the .vsix file once downloaded?

Splike on 11 Jun 2018

yzhang-gh on 11 Jun 2018

That worked! Thanks so much!

I don't know why installing from the .vsix file works, but when I uninstalled the extension and re-installed it through the marketplace, it gave me an error.

Splike on 11 Jun 2018

I also have no idea... but I will leave this issue open to see whether there are other people seeing this error.

yzhang-gh on 11 Jun 2018

After installing from the .vsix file, my my bold lines have changed.

If the line ends in a period, it stays orange as it did before. But now when there is no period, the surrounding stars are grey and the text it white.

Is this an error or on purpose?

Splike on 11 Jun 2018

This is a working-in-progress feature and I haven't added an option to enable/disable it.

To disable this, you can navigate to [your user home]/.vscode/extensions/yzhang.markdown-all-in-one-1.4.0/out/extension.js and comment out line 33 decorations.activiate(context);

Related #185.

yzhang-gh on 11 Jun 2018

Ah, very neat!

I'm looking forward to see if this is something i'd use or not.

Hi there, I'm having the same issue. It was working fine up until a few days ago. I tried installing the plugin from the .vsix file but I am still getting a similar error. Here is my debug output:

Still no more information with this error log. What's your Markdown file extension? .md? or something else?

yzhang-gh on 14 Jun 2018

It's definitely .md. I've tried exporting to HTML for a file that I was
able to previously and it no longer works.

I have packaged a debug build markdown-all-in-one-1.4.0-debug.zip.

Could you install this one and try to print again, then tell me the debug output?

yzhang-gh on 14 Jun 2018

Sure, I won't be able to test it for a few hours I'm afraid. I'll let you
know how it goes.

I also had the same error with the latest regular vsvcode version. I now tried your debug build of the extension from above and it works with that.

darkmattercoder on 14 Jun 2018

After .vsix plugin installation, my issue was fixed. But I also have returned from my work place, where I have a restricted and very slow internet access. Does your extension use any online tools to print an HTML from a MD?

JeffRockatansky on 14 Jun 2018

No, it should be offline. The only thing that needs network is the math rendering if you open the HTML in the browser. The printing process itself doesn't require internet access and should be fast.

yzhang-gh on 15 Jun 2018

I was encountering the same issue on Windows with the latest VS Code. Updating to the latest CI Build fixed the issue.

I am encountering the same issue.

There will be a new version several hours later.

Running the contributed command:'markdown.extension.printToHtml' failed. error happens when I execute the Markdown: Print current to HTML command if only [Preview] window open. Otherwise it works. On v1.5.1 (Win10 x64)
