To post a block of code wihout having Discourse/Markdown try to colour words based upon its guess which language it’s written in, append “text” to the three back-ticks that begin the code block. For example:
``` Drop the apostrophe or else I'll shoot. ```
will highlight “Drop”, “else”, and the “ll” of “I’ll” as folows.
Drop the apostrophe or else I'll shoot.
But if you use:
```text Drop the apostrophe or else I'll shoot. ```
Drop the apostrophe or else I'll shoot.
it will leave your text alone.
