            Bug ID: 453082
           Summary: Okular could support syntax color annotation for code
                    blocks
           Product: okular
           Version: 21.12.3
          Platform: Debian testing
                OS: Linux
            Status: REPORTED
          Severity: wishlist
          Priority: NOR
         Component: markdown backend
          Assignee: okular-devel at kde.org
          Reporter: tnemeth at free.fr
  Target Milestone: ---

SUMMARY
Displaying a markdown file having annotated code blocks could be more beautiful
if syntax highlight were used.
Blockquotes could also benefit of a different hightlight...


STEPS TO REPRODUCE
1. Create a markdown file using anontated code and citation blocks, eg:

------8<------8<------
Create a source file `hello.c`:

```C
#include <stdio.h>
int main(void)
{
   print("Hello world\n");
   return 0;
}
```

Build the source:

```Shell
gcc -o hello hello.c
```

A quote from Confucius who said:

> Demand a lot from yourself and expect little from others. This will save you a lot of trouble.

...
------8<------8<------

2. Display the markdown file in Okular

OBSERVED RESULT
No syntax highlight on source code blocks, no emphasis on the quote.

EXPECTED RESULT
Beautiful code with fixed-size fonts and syntax highlight for code blocks,
something nice for the quote.
