prior art as a reference

In this one image are several features that I'd love to see reedline strive to attain.

• context aware syntax highlighting - note how the string 'Hello world' is colored differently from python keywords
• configurable line continuation character(s) - note the ... on the second line
• it's hard to miss the drop down combo box with scroll bar - no clue how to achieve this one, maybe tui? i guess this population would be language specific, but of course, i'm thinking about nushell. :) a use case is to use this with completions of sub commands in nushell and completions in general.
• the status bar - would be nice to show hints, errors, etc in a status bar, opt-in configurable, of course

some of these we're well on our way to achieving.

This is taken from here and the github repo.

For reference, i found this collection of supported ansi escape sequences very informative.

To be clear, i'm not talking about baking in python or this python line editor. I'm just using it as a prior art reference.

Start by reviewing the issue image and the linked python-prompt-toolkit documentation and repository. Separate the requested completion dropdown and status bar from the already checked capabilities, then confirm a narrower scope and acceptance criteria before identifying the relevant reedline entry points. Done should mean one agreed feature is implemented and its behavior is demonstrated.
