<h2>Known failures</h2>
|
|||
|
|
<p>There are certain edge cases where Prism will fail.
|
|||
|
|
There are always such cases in every regex-based syntax highlighter.
|
|||
|
|
However, Prism dares to be open and honest about them.
|
|||
|
|
If a failure is listed here, it doesn’t mean it will never be fixed. This is more of a “known bugs” list, just with a certain type of bug.
