[BUG] Syntax.highlight adds newline
See original GitHub issueDescribe the bug
Highlighting some code that ends with a newline produces the same Text as without a newline:
from rich.syntax import Syntax
Syntax("", "python").highlight("print('hello')")
# shows: <text "print('hello')\n" ...
Syntax("", "python").highlight("print('hello')\n")
# shows: <text "print('hello')\n" ...
Platform
Linux, LXTerminal
$ python -m rich.diagnose

Keep me posted re progress. 😃
I was just about to put in a feature request related to this.
The “problem” noted by @davidbrochart is caused by https://github.com/Textualize/rich/blob/5f0219786bbaf994061011df087602d5edff5d66/rich/syntax.py#L522 Having an optional parameter to disable the addition of a newline character would be an easy way to take care of the original issue.
I will file a separate issue for the feature request.
