is it possible to add a feature colourful R prompt in terminal without having the issue explained in the link below?

I can think in two ways of colorizing R prompt:

  1. Putting something like options(prompt = "\x1b[33m>\x1b[0m ") in the Rprofile.
  2. Running R in a Neovim's buffer and "syntax" highlighting the prompt.

However, since the goal of the plugin is to help in the development of R scripts, I prefer to colorize only R output because the input is already highlighted in the script and I don't want distractions in the output. Currently, when running R in a Neovim buffer, all lines beginning with ">" are either highlighted with a single color (the default) or highlighted as R code (see options rout_color_input and Rout_more_colors).

Unfortunately, first is out of option because of strange behaviour when using the command history (arrow up/down). I didn't know about latter option. I will give it a try, thanks for the answer.

You can try this in your vimrc:

autocmd FileType rout syn region routInput start="^>" end='$' contains=routPrompt keepend | syn match routPrompt "^>" contained
hi def link routPrompt Special

In this case, the option Rout_more_colors will be ignored. You have to adjust the code above if either your prompt is not ">" or you prefer to highlight the prompt using a highlighting group other than Special.
