highlighter inconsistently highlights

[dyslexicanaboko]

Hi,

I am not sure what to provide you exactly so I am hoping to converse with you in the comments or via email if you'd prefer. I have used the crayon syntax highlighter for a long time, I upgraded to this highlighter and it is half working. Thank you for picking up the project.

Bizarre behavior

• Some of my existing posts worked right away, no changes on my part
• New posts I have created are a total crapshoot - sometimes it works and sometimes it doesn't
• The Urvanov editor doesn't work too well, it takes my code and smashes it together then doesn't render using the syntax highlighter

Examples

If you view the page source you can clearly see that these pages are doing different things:

• https://obscureproblemsandgotchas.com/development/sql-server/small-date-time-is-garbage-and-you-should-stop-using-it/
  • You can see that the syntax highlighter is working just fine here
  • When you look at the page source you see that all the divs rendered with appropriate classes etc
  • On this page I am using the Word Press "Blocks", I added a "Code Block" and added the "lang:tsql" class. This worked.
• https://obscureproblemsandgotchas.com/development/sql-server/enlarging-a-char-column/
  • The syntax highlighter is not working here at all
  • I tried using a "Code Block", I tried using a "pre" tag and nothing seems to work
  • I left the code in a "pre" tag so that it would look a little nicer
  • When you look at the page source you see that only the pre tag renders, nothing is replaced

I checked the header of both pages and the urvanov CDN declarations are present.

Could you please help me figure out what I am doing wrong or maybe there is a bug?

In my forked version you should use special block named "Urvanov Syntax Highlighter". I don't sure about "Code Block" and it is strange that it worked for you.

@dyslexicanaboko Maybe you have some messages in log file inside plugin directory? Check if logging is enabled in the plugin and try to see what is in the log file. The log works the same as it worked for Crayon.

And I will try to check your code examples from the page were the plugin does not work. Maybe I will find some solutions.

Hello - my apologies for not getting back to you sooner. Ever since the pandemic started things have been absolutely horrible for me at work. I work in the medical industry so we got hit hard.

I have been toying around again and I can't say I have gotten much better progress. I wanted to share with you one observation I have made. When I first post something with code in it I don't see any highlighting. However, when I press the "Refresh" button on the syntax highlighter page it seems to fix the highlighting I don't understand why.

Here is the output of the log:

I am going to try to keep debugging and get back to you.

I have tried using the "Urvanov Syntax Highlighter" block and it just smashes the code together. It's very odd.

I had a chance to make a post again and I have confirmed that the only way the syntax highlighter is working for me is to do the following:

1. Use the "Urvanov Syntax Highlighter" block directly.
   1. Don't convert from any other block first this will screw it up.
2. Click on the block's title "Urvanov Syntax Highlighter" and wait for the editor to appear
3. Enter code
4. Publish post
   1. At this point the syntax will not be highlighted
5. Go to "~/wp-admin/options-general.php?page=urvanov_syntax_highlighter_settings"
6. Press the "Refresh" button located in the "Posts" section of the page
7. Refresh your post's page and you will see syntax highlighting

If I don't follow these steps it doesn't work. This is more progress than before so that's good. At least now I can make it work, before nothing worked.

1. Yes, you must use this block. I never tried to check convertion from any other block. I will fix it in future, but for now it is not sever error. I think.

Steps 6-7 looks strange for me, because in my site I don't do them. Maybe after some time I will find out what is wrong.
