Summary of Changes

Hello @bajrangCoder, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the terminal experience in Alpine environments by implementing a smart path shortening mechanism for the command prompt. The primary goal is to make the prompt more concise and informative, allowing users to quickly grasp their current directory without clutter, while also providing immediate visual feedback on the success or failure of the last executed command. This feature aims to improve the overall usability and aesthetics of the terminal interface.

Highlights

• Smart Path Shortening: A new bash function, _shorten_path, has been introduced to intelligently abbreviate the current working directory in the terminal prompt. This function transforms paths like ~/projects/my-app/src into ~/p/m/src for improved readability.
• Dynamic Prompt Updates: The PROMPT_COMMAND has been configured to execute before each prompt, dynamically updating the prompt with the shortened path and the exit status of the previously executed command.
• Enhanced PS1 Configuration: The PS1 environment variable has been modified to incorporate the new shortened path and to visually indicate command success or failure by changing the prompt's color (red for failure).

Code Review

This pull request introduces a smart path shortening feature for the terminal prompt, which is a great enhancement for usability. The overall implementation is good, but I found a logical issue in the _shorten_path function that can cause incorrect path display in the edge case where the user's home directory is the root (/). I've provided a more robust implementation to address this. The accompanying changes to the PS1 prompt to use this function and display the exit status of commands are well-implemented.

Are you sure it doesn't causes visual glitches in xterm.js? Because previous issue was caused by PS1
