Rework of the chat app

[calderonsamuel]

Sorry for the delay, the last touches of the app had subtle but important problems that needed to be fixed before the PR. Here I'll explain incrementally the new features and the reworks.

New look of the message history

Each individual message is now rounded and has an icon indicating whether it comes from the user or from the assistant. Each role has a different horizontal aligment and a slightly different background color.

Simplified user inputs

The prompt and buttons have been simplified to give the chat more room to expand.

Now the app has a settings button where the user can still choose its skill level and prefered style.

Welcome message with instructions

When the app starts (or history is cleared) the assistant greets the user with a random welcome message and instructions on how to use the app.

The chat can be adjusted vertically, horizontally and is scrollable

Limited to 800px width. The prompt input is always fixed to the bottom of the app.

The chat inherits the current rstudio theme

This makes it look more integrated with the IDE. I believe this gives the feel of what an extension does in VScode.

Copy to clipboard button in code chunks

Every code chunk now has on top a bar indicating the language of the code displayed and a "Copy" button. When the user clicks the button writes the code in the clipboard and shows a short "Copied" feedback in the button.

Custom scrollbar

The app uses now a narrower grey scrollbar.

Notes

Although the main focus of the rework focused on the chat app, some changes in internals were needed. I also had to structure the app in modules to better isolate all internal logic and functions. Also, I dropped the import of {dplyr} because it wasn't really needed.

I have documented almost every new function and module that I have added and made sure that the changes pass all the previous tests and the ones that I added.

I'll migrate every Issue on my fork to this repository. There are some little bugs that should be fixed before next CRAN submission, but I believe it is ready now to be tested by the public.

This looks incredible! Fantastic work. I'll take a deep dive tomorrow (Monday) and hope to have it merged soon.

If it's okay with you, I'd like to list you as an author for the package given such a significant contribution.

[calderonsamuel]

Sure! Here is the info I use for my own packages:

person("Samuel", "Calderon", , "samuel.calderon@uarm.pe", role = c("aut", "cre"),
           comment = c(ORCID = "0000-0001-6847-1210"))

Feel free to edit the role and let me know if you need anything else.
