undefined error when loading script

[close2infinity]

@milan-rusev

Expected behaviour

Script should be able to render content

Actual behaviour

• Content is rendered using the standard QOwnNotes mechanism
• In the log, I see that MarkDownIt.markdownit(..) returns undefined

Steps to reproduce

• Install markdown-it as the only script
• Reload Script Engine
• Try to render a note

[13:51:07] [status] The scripting engine was reloaded

[pbek]

First please update to the latest version of QOwnNotes, then remove the script and install it again.

[close2infinity]

Sorry - I thought I had updated, but it seems the old version was still in memory. I updated to version 18.09.1 and reinstalled the script. However, the issue persists.

[pbek]

Then it's best to post that issue on https://github.com/qownnotes/scripts/issues and mention the authors of the script.

[pbek]

That's the line of the script: https://github.com/qownnotes/scripts/blob/master/markdown-it/markdown-it.qml#L59

[close2infinity]

Hi, thx for the comments. I originally missed that this issue list is for all scripts - I updated the issue and included @MilanRusev, who I assume is the author.

[pbek]

Then it's best to post that issue on https://github.com/qownnotes/scripts/issues

oh, sorry. we already are on https://github.com/qownnotes/scripts/issues :D

[pbek]

btw. can you please execute ls -hal /home/fschoenh/.local/share/PBE/QOwnNotes/scripts/markdown-it/ and post the result.

I tried debugging this myself despite my very limited Javascript expertise.

• The .js file seems to be loaded - renaming it results in a different error
• MarkdownIt.markdownit is undefined for some reason, so the most likely culprit is the rather complex exports definition in the first line of the file

[pbek]

It's really strange, it works flawlessly for me...

You could try downloading https://github.com/markdown-it/markdown-it/blob/master/dist/markdown-it.js directly...

[close2infinity]

I'll try that, thx for the support.

[close2infinity]

I found the issue. For some reason, on my system the imported script needs be referred to as 'this' instead of 'MarkdownIt'. I changed Line 59 to:

md = new this.markdownit(optionsObj);

... and now it works. I fear I know QML even less than I do know JavaScript - is there any explanation for this behavior?

[pbek]

so your system ignores the MarkdownIt part of import "markdown-it.js" as MarkdownIt, very strange

[pbek]

but according to https://doc.qt.io/qt-5/qtqml-syntax-imports.html the as should work

[pbek]

also in Qt 5.5 and 5.6: https://doc.qt.io/archives/qt-5.5/qtqml-syntax-imports.html

[pbek]

Do you use stock Ubuntu or some derivative distribution? Because you are using Qt 5.6.1 instead of the stock 5.5.1 of Ubuntu 16.04.

[close2infinity]

I have a Kubuntu 16.04

[pbek]

Interesting, I didn't know that the Qt version was getting updated by Kubuntu... or do you use a special repository for Qt?

[close2infinity]

I think I'm using the stock Kubuntu KDE, but this is a three years old dev system, so I might have added some PPAs I'm not aware of anymore.

xenialoverlay1, seems like an Ubuntu maintained overlay for Kubuntu...

In any case, I guess we can close that issue now. It "should" work on all systems according to the Qt documentation... :)

[close2infinity]

Yes, thx for the support :-)

[pbek]

Hehe, good you found a solution yourself. ;)
