R console prompt configuration

[EmilHvitfeldt]

Positron Version:

Steps to reproduce the issue:

I used to use https://github.com/gaborcsardi/prompt in RStudio to great success. In Positron this doesn't work well 😅

1. run prompt::set_prompt(prompt::prompt_fancy)

What did you expect to happen?

I'm not the only user of {prompt}, but current results are unusable.

This configuration is generally set in . Rprofile, so a new positron user might see this when they first boot up.

Were there any error messages in the output or Developer Tools console?

Nope

I don't know where this should be fixed. here or in the package. But I feel that

a. getting the current output is bad
b. people should be able to modify their console prompt

It looks like simple ones like prompt_git() work, but fancier ones with Unicode like prompt_fancy() don't.

My guess is that the special prompt field we have in the Console is not getting treated as if it could have Unicode in it, making this a question for @softwarenerd.

@softwarenerd you can reproduce this with:

# First install this R package
pak::pak("gaborcsardi/prompt")

Then run:

prompt::set_prompt(prompt::prompt_fancy)

Hit Enter afterwards to ensure the prompt is updated, and it should look like the image above.

If you are in a git repo, you can also try

prompt::set_prompt(prompt::prompt_git)

that should work, and should show you the branch name as a simple character string (no unicode)
