Rust Shell for LLM

TODO: collapasable, copyable, download, etc

Let's write a Rust shell together. It should startup a CLI LLM program. Once it is ready to take our input, we can take the input from the user and then send it to the CLI program. We should echo the output that comes back. Once that output is finished, we can take more input. Given this --help, please think about how you would design this shell program and then think through how you would write the Rust code. Then output the Rust source

Here's an outline of the design and implementation process:

Design Considerations

1. Parsing Command-Line Arguments: Utilize a Rust library like clap or structopt for parsing command-line arguments and providing a help message.

2. Interactive Mode: The shell should have an interactive mode where it accepts user input, sends it to the CLI program, and displays the output. This mode is activated with -i or --interactive.

3. Immediate Interactive Mode: An option --interactive-first to immediately start the shell in interactive mode without waiting for additional user input.

4. Instruction Mode: Include an instruction mode (-ins, --instruct) specifically for Alpaca models.

5. Multiline Input: Support for multiline inputs, allowing users to write or paste multiple lines.

6. Reverse Prompt Handling: Implement functionality to halt generation at specific prompts (-r, --reverse-prompt).

7. Colored Output: An option to colorize output (--color) for better distinction between prompts, user input, and generated content.

8. Configurable Options: Support for various options like seed, threads, prompt customization, cache handling, sampling methods, penalties, and others.

9. Logging and Debugging Options: Implement logging capabilities as per the provided options.

10. Error Handling and Validation: Robust error handling and validation of inputs and command-line arguments.

11. Extensibility and Modularity: Design the shell in a way that it's easy to extend and modify.

12. Documentation and Help: Implement a detailed help section based on the provided --help command.

• Provide installation instructions.

Rust Source Code Outline

The actual Rust source code would be quite extensive, given the complexity and the number of features to be implemented. Here is a very high-level outline:

// Dependencies and modules
extern crate clap;
use clap::{App, Arg};

// Main function
fn main() {
    // Parse command-line arguments
    let matches = App::new("Mistral CLI Shell")
        .version("0.1")
        .author("Author Name")
        .about("Interacts with LLM CLI")
        // Add arguments and options
        .get_matches();

    // Determine the mode of operation and other options based on arguments
    // ...

    // Interactive mode loop
    if matches.is_present("interactive") {
        run_interactive_mode();
    }

    // Other modes and functionalities
    // ...
}

// Function to handle interactive mode
fn run_interactive_mode() {
    // Loop to take user input and interact with LLM CLI
    // ...
}

// Additional functions for other features
// ...

This outline provides a general idea of how the program could be structured. The actual implementation would be more detailed and involve handling all the specified options and ensuring robust interaction with the LLM CLI program.:etlet's just focus on how we would execute the mistral CLI and how we would detect that it is ready to take input from the user as it takes a while to startup.I'm sorry,To focus on executing the Mistral CLI and detecting when it's ready to take user input, especially considering its startup time, you can follow these steps in Rust:

1. Spawning the Mistral Process: Use Rust's std::process::{Command, Child} to spawn the Mistral CLI process. This involves setting up the command with necessary arguments and starting it in a way that allows for bidirectional communication.

2. Inter-process Communication: Establish a non-blocking mechanism to read from the Mistral process's standard output (stdout). This can be achieved by setting up asynchronous reads or using threads.

3. Detecting Readiness: Implement a method to detect when Mistral is ready to accept input. This could be based on specific output patterns or signals that Mistral emits upon startup completion.

4. Handling User Input: Once Mistral is ready, set up a loop to take user input and send it to Mistral's standard input (stdin).

5. Receiving and Displaying Output: Continuously read the output from Mistral and display it to the user.

Here is a simplified Rust code outline to demonstrate this process:

use std::io::{self, Write, BufReader, BufRead};
use std::process::{Command, Stdio, Child};
use std::thread;
use std::sync::mpsc;

fn main() -> io::Result<()> {
    // Spawn the Mistral process
    let mut child = Command::new("./mistral-7b-instruct-v0.1-Q4_K_M-main.llamafile")
        .args(["--interactive"]) // Add other necessary arguments here
        .stdin(Stdio::piped())
        .stdout(Stdio::piped())
        .spawn()?;

    // Get handles to stdin and stdout
    let mut stdin = child.stdin.take().expect("Failed to open stdin");
    let stdout = child.stdout.take().expect("Failed to open stdout");

    // Setup asynchronous reading from stdout
    let (tx, rx) = mpsc::channel();
    thread::spawn(move || {
        let reader = BufReader::new(stdout);
        for line in reader.lines() {
            if let Ok(line) = line {
                tx.send(line).expect("Failed to send line to main thread");
            }
        }
    });

    // Detect when Mistral is ready (based on specific output pattern)
    for line in &rx {
        println!("Mistral: {}", line);
        if line.contains("ready pattern or signal") { // Replace with actual readiness indicator
            break;
        }
    }

    // Take user input and send it to Mistral
    let mut user_input = String::new();
    while io::stdin().read_line(&mut user_input).expect("Failed to read line") > 0 {
        stdin.write_all(user_input.as_bytes()).expect("Failed to write to stdin");
        stdin.flush().expect("Failed to flush stdin");

        // Optionally wait and display the response from Mistral
        if let Ok(line) = rx.recv() {
            println!("Mistral: {}", line);
        }

        user_input.clear();
    }

    // Optionally handle the termination of the Mistral process
    child.wait()?;

    Ok(())
}

This code is a basic framework and might require adjustments based on the specific behaviors and outputs of the Mistral CLI. The key aspects are:

• Spawning the Mistral process with bidirectional communication.
• Reading its output asynchronously to detect readiness.
• Interacting with the process through user input and displaying the CLI's responses.Given the --help I gave you, is there a certain mode that we should launch the CLI in that would make it easier to detect when itis ready?Based on the --help information you provided for the Mistral CLI, there are a few options that can be particularly useful for determining when the CLI is ready to accept input. One such option is --interactive-first. When this option is used, the CLI program runs in interactive mode and waits for input right away. This behavior can simplify the detection of when the program is ready, as you can expect it to be ready for input as soon as it starts, without having to parse specific output patterns to determine readiness.

Here's how you can adjust the Rust shell program to utilize the --interactive-first option:

1. Launch the CLI in Interactive-First Mode: Modify the command to start the Mistral CLI with the --interactive-first option. This ensures the program is immediately ready for user input upon startup.

2. Readiness Detection: Since the --interactive-first mode implies readiness right after startup, you don't need to look for specific output patterns to confirm readiness. You can assume the CLI is ready for input as soon as it launches.

3. User Input Loop: Implement a loop to take user input and send it to the CLI's standard input.

Here's the updated Rust code snippet reflecting these changes:

use std::io::{self, Write, BufReader, BufRead};
use std::process::{Command, Stdio};
use std::thread;
use std::sync::mpsc;

fn main() -> io::Result<()> {
    // Spawn the Mistral process in interactive-first mode
    let mut child = Command::new("./mistral-7b-instruct-v0.1-Q4_K_M-main.llamafile")
        .args(["--interactive-first"]) // Using interactive-first mode
        .stdin(Stdio::piped())
        .stdout(Stdio::piped())
        .spawn()?;

    // Get handles to stdin and stdout
    let mut stdin = child.stdin.take().expect("Failed to open stdin");
    let stdout = child.stdout.take().expect("Failed to open stdout");

    // Setup asynchronous reading from stdout
    let (tx, rx) = mpsc::channel();
    thread::spawn(move || {
        let reader = BufReader::new(stdout);
        for line in reader.lines() {
            if let Ok(line) = line {
                tx.send(line).expect("Failed to send line to main thread");
            }
        }
    });

    // Mistral is ready for input - no specific output pattern checking needed
    println!("Mistral is ready for input.");

    // Take user input and send it to Mistral
    let mut user_input = String::new();
    while io::stdin().read_line(&mut user_input).expect("Failed to read line") > 0 {
        stdin.write_all(user_input.as_bytes()).expect("Failed to write to stdin");
        stdin.flush().expect("Failed to flush stdin");

        // Display the response from Mistral
        if let Ok(line) = rx.recv() {
            println!("Mistral: {}", line);
        }

        user_input.clear();
    }

    // Handle the termination of the Mistral process
    child.wait()?;

    Ok(())
}

In this version, the program starts the Mistral CLI in --interactive-first mode, which streamlines the process by removing the need to detect specific output patterns for readiness. The rest of the program remains focused on handling user input and displaying the CLI's output.Please output updated source code if we use --interactive-firstCertainly! When using the --interactive-first option with the Mistral CLI, the updated Rust source code to handle the interaction becomes simpler as we no longer need to detect a specific output pattern for readiness. The program can immediately proceed to handle user input and relay it to the CLI. Here's the updated source code:

use std::io::{self, Write, BufReader, BufRead};
use std::process::{Command, Stdio};
use std::thread;
use std::sync::mpsc;

fn main() -> io::Result<()> {
    // Spawn the Mistral process in interactive-first mode
    let mut child = Command::new("./mistral-7b-instruct-v0.1-Q4_K_M-main.llamafile")
        .args(["--interactive-first"]) // Launching in interactive-first mode
        .stdin(Stdio::piped())
        .stdout(Stdio::piped())
        .spawn()?;

    // Get handles to stdin and stdout
    let mut stdin = child.stdin.take().expect("Failed to open stdin");
    let stdout = child.stdout.take().expect("Failed to open stdout");

    // Setup asynchronous reading from stdout
    let (tx, rx) = mpsc::channel();
    thread::spawn(move || {
        let reader = BufReader::new(stdout);
        for line in reader.lines() {
            if let Ok(line) = line {
                tx.send(line).expect("Failed to send line to main thread");
            }
        }
    });

    // Mistral is ready for input immediately
    println!("Mistral is ready for input.");

    // Continuously take user input and send it to Mistral's stdin
    let mut user_input = String::new();
    while io::stdin().read_line(&mut user_input).expect("Failed to read line") > 0 {
        stdin.write_all(user_input.as_bytes()).expect("Failed to write to stdin");
        stdin.flush().expect("Failed to flush stdin");

        // Display the response from Mistral
        if let Ok(line) = rx.recv() {
            println!("Mistral: {}", line);
        }

        user_input.clear();
    }

    // Handle the termination of the Mistral process
    child.wait()?;

    Ok(())
}

In this code:

• The Mistral process is started with the --interactive-first option, indicating that it is ready to accept input immediately after startup.
• A non-blocking reader is set up to asynchronously read from Mistral's stdout.
• The main loop waits for user input, sends it to Mistral, and then waits for and displays the response.
• Proper error handling and resource management are ensured throughout the process.Your code is great! But I found an issue. If I send a message, it outputs Mistral and nothing more. If I type a second message then it shows the intial response that was hidden from mistral. Any ideas? if you know how to fix the bug, can you output a fixed source?The issue you're experiencing seems to be related to the synchronization between sending input to the Mistral CLI and receiving its output. It appears that the output from the first input is only displayed after sending the second input. This can be a result of the asynchronous handling of stdout and the timing of reading from the channel.

To address this, we can modify the program to ensure that it reads all available output from Mistral before prompting for the next input. This can be done by continuously reading from the channel until it's empty, which indicates that Mistral has finished responding to the input. Here's the updated source code with this fix:

use std::io::{self, Write, BufReader, BufRead};
use std::process::{Command, Stdio};
use std::thread;
use std::sync::mpsc;
use std::time::Duration;

fn main() -> io::Result<()> {
    // Spawn the Mistral process in interactive-first mode
    let mut child = Command::new("./mistral-7b-instruct-v0.1-Q4_K_M-main.llamafile")
        .args(["--interactive-first"]) // Launching in interactive-first mode
        .stdin(Stdio::piped())
        .stdout(Stdio::piped())
        .spawn()?;

    // Get handles to stdin and stdout
    let mut stdin = child.stdin.take().expect("Failed to open stdin");
    let stdout = child.stdout.take().expect("Failed to open stdout");

    // Setup asynchronous reading from stdout
    let (tx, rx) = mpsc::channel();
    thread::spawn(move || {
        let reader = BufReader::new(stdout);
        for line in reader.lines() {
            if let Ok(line) = line {
                tx.send(line).expect("Failed to send line to main thread");
            }
        }
    });

    println!("Mistral is ready for input.");

    // Continuously take user input and send it to Mistral's stdin
    let mut user_input = String::new();
    while io::stdin().read_line(&mut user_input).expect("Failed to read line") > 0 {
        stdin.write_all(user_input.as_bytes()).expect("Failed to write to stdin");
        stdin.flush().expect("Failed to flush stdin");

        // Display all available responses from Mistral
        while let Ok(line) = rx.recv_timeout(Duration::from_millis(100)) {
            println!("Mistral: {}", line);
        }

        user_input.clear();
    }

    // Handle the termination of the Mistral process
    child.wait()?;

    Ok(())
}

In this updated code:

• After sending input to Mistral, the program now uses recv_timeout to continuously read from the channel until there's a timeout (indicating no more output is currently available from Mistral).
• The timeout duration of 100 milliseconds is set arbitrarily; you might need to adjust this value based on the responsiveness of the Mistral CLI in your environment.

This approach ensures that all available output from Mistral is read and displayed before the next user input is requested, which should resolve the issue of delayed output display.That was wrose. Nothing was output until I hit enterIt seems the issue lies in how the program handles the asynchronous output from the Mistral CLI. The previous modification using recv_timeout might have been too aggressive in waiting for the output, causing it to skip displaying until the next input. Let's revert to continuous reading but add a mechanism to check if Mistral has completed its response.

One approach is to look for a specific pattern or signal in the output that indicates Mistral has finished responding. However, if such a pattern is not available or consistent, we need a different strategy.

We can improve the responsiveness by using non-blocking reads from the channel. This way, the program can immediately display any output from Mistral as soon as it's available, without waiting for the user to input something again. Here's the revised code:

use std::io::{self, Write, BufReader, BufRead};
use std::process::{Command, Stdio};
use std::thread;
use std::sync::mpsc::{self, TryRecvError};
use std::time::Duration;

fn main() -> io::Result<()> {
    // Spawn the Mistral process in interactive-first mode
    let mut child = Command::new("./mistral-7b-instruct-v0.1-Q4_K_M-main.llamafile")
        .args(["--interactive-first"]) // Launching in interactive-first mode
        .stdin(Stdio::piped())
        .stdout(Stdio::piped())
        .spawn()?;

    // Get handles to stdin and stdout
    let mut stdin = child.stdin.take().expect("Failed to open stdin");
    let stdout = child.stdout.take().expect("Failed to open stdout");

    // Setup asynchronous reading from stdout
    let (tx, rx) = mpsc::channel();
    thread::spawn(move || {
        let reader = BufReader::new(stdout);
        for line in reader.lines() {
            if let Ok(line) = line {
                tx.send(line).expect("Failed to send line to main thread");
            }
        }
    });

    println!("Mistral is ready for input.");

    // Continuously take user input and send it to Mistral's stdin
    let mut user_input = String::new();
    while io::stdin().read_line(&mut user_input).expect("Failed to read line") > 0 {
        stdin.write_all(user_input.as_bytes()).expect("Failed to write to stdin");
        stdin.flush().expect("Failed to flush stdin");

        // Non-blocking read to display any available output from Mistral
        loop {
            match rx.try_recv() {
                Ok(line) => println!("Mistral: {}", line),
                Err(TryRecvError::Empty) => {
                    // Wait a bit before trying again to avoid tight looping
                    thread::sleep(Duration::from_millis(100));
                    break;
                }
                Err(TryRecvError::Disconnected) => break,
            }

    // Handle the termination of the Mistral process
    child.wait()?;

    Ok(())
}

In this revised version:

• The program uses try_recv in a loop to read from the channel. This is a non-blocking operation.
• If try_recv encounters an Empty error, it means there's currently no output from Mistral. The program then pauses briefly (with thread::sleep) before breaking out of the loop to wait for the next user input.
• This approach should allow for immediate display of any output from Mistral as soon as it's available, without waiting for an additional user input trigger.How would you extend this code to write a stand-alone program that takes input from text file A.txt and sends it to mistral, then reads the output, then breaks up the input line by line and calls mistaral with a prompt for each lineTo extend the current program to read input from a text file A.txt, send each line as a prompt to the Mistral CLI, and then read and process the output for each line, we need to modify the program to include file reading and processing logic. The program will:

1. Read the contents of A.txt.
2. For each line in A.txt, send it as a prompt to the Mistral CLI.
3. Read the output from Mistral for each prompt.
4. Process or display the output accordingly.

Here's the revised Rust code to achieve this:

use std::io::{self, BufReader, BufRead, Write};
use std::fs::File;
use std::process::{Command, Stdio};
use std::thread;
use std::sync::mpsc::{self, TryRecvError};
use std::time::Duration;

fn main() -> io::Result<()> {
    // Open the file
    let file = File::open("A.txt")?;
    let reader = BufReader::new(file);

    // Spawn the Mistral process in interactive-first mode
    let mut child = Command::new("./mistral-7b-instruct-v0.1-Q4_K_M-main.llamafile")
        .args(["--interactive-first"]) // Launching in interactive-first mode
        .stdin(Stdio::piped())
        .stdout(Stdio::piped())
        .spawn()?;

    // Get handles to stdin and stdout
    let mut stdin = child.stdin.take().expect("Failed to open stdin");
    let stdout = child.stdout.take().expect("Failed to open stdout");

    // Setup asynchronous reading from stdout
    let (tx, rx) = mpsc::channel();
    thread::spawn(move || {
        let output_reader = BufReader::new(stdout);
        for line in output_reader.lines() {
            if let Ok(line) = line {
                tx.send(line).expect("Failed to send line to main thread");
            }
        }
    });

    println!("Mistral is ready for input.");

    // Process each line from the file
    for line in reader.lines() {
        let line = line.expect("Failed to read line from file");
        
        // Send the line to Mistral's stdin
        stdin.write_all(line.as_bytes()).expect("Failed to write to stdin");
        stdin.write_all(b"\n").expect("Failed to write newline to stdin");
        stdin.flush().expect("Failed to flush stdin");

        // Read and display the output from Mistral for this line
        loop {
            match rx.try_recv() {
                Ok(output_line) => println!("Mistral: {}", output_line),
                Err(TryRecvError::Empty) => {
                    thread::sleep(Duration::from_millis(100));
                    break;
                }
                Err(TryRecvError::Disconnected) => break,
            }
        }
    }

    // Handle the termination of the Mistral process
    child.wait()?;

    Ok(())
}

This program now opens A.txt, reads each line, and sends each line to the Mistral CLI as a prompt. After sending each line, it reads the output from Mistral before proceeding to the next line. This is a basic implementation and may need to be adjusted depending on the specifics of how Mistral processes and responds to each line of input.

It's important to note that this approach assumes Mistral processes each line independently and completes its response before the next line is sent. If Mistral's behavior is different, further modifications may be needed. For instance, if Mistral requires a specific signal to indicate the end of input, you would need to send that signal after each line.I think this should be a syncrhonous program, because the CLI isn't multi-threaded and we need to wait for it's output to finishIf the Mistral CLI isn't multi-threaded and requires synchronous interaction, where we need to wait for its output to complete before sending the next input, the program structure changes significantly. Instead of using asynchronous reading with channels, we'll read from the CLI's output synchronously in the main thread. This approach ensures that we process each line of input from the file and wait for the complete output from the CLI before proceeding to the next line.

Here's the updated Rust code for a synchronous interaction:

use std::io::{self, BufReader, BufRead, Write};
use std::fs::File;
use std::process::{Command, Stdio};

fn main() -> io::Result<()> {
    // Open the file
    let file = File::open("A.txt")?;
    let reader = BufReader::new(file);

    // Spawn the Mistral process in interactive-first mode
    let mut child = Command::new("./mistral-7b-instruct-v0.1-Q4_K_M-main.llamafile")
        .args(["--interactive-first"]) // Launching in interactive-first mode
        .stdin(Stdio::piped())
        .stdout(Stdio::piped())
        .stderr(Stdio::inherit()) // To capture any error output directly
        .spawn()?;

    // Get handles to stdin and stdout
    let mut stdin = child.stdin.take().expect("Failed to open stdin");
    let mut stdout = BufReader::new(child.stdout.take().expect("Failed to open stdout"));

    println!("Mistral is ready for input.");

    // Process each line from the file
    for line in reader.lines() {
        let line = line.expect("Failed to read line from file");

        // Send the line to Mistral's stdin
        stdin.write_all(line.as_bytes()).expect("Failed to write to stdin");
        stdin.write_all(b"\n").expect("Failed to write newline to stdin");
        stdin.flush().expect("Failed to flush stdin");

        // Read and display the output from Mistral for this line
        let mut output_line = String::new();
        while stdout.read_line(&mut output_line).expect("Failed to read from stdout") > 0 {
            // Process the output line
            println!("Mistral: {}", output_line.trim_end());
            if output_line.trim_end().is_empty() {
                // Assuming an empty line indicates end of Mistral's response
                break;
            }
            output_line.clear();
        }
    }

    // Handle the termination of the Mistral process
    child.wait()?;

    Ok(())
}

In this version:

• The program reads each line from the file A.txt and sends it to the Mistral CLI.
• It then reads the output from the CLI line by line in a synchronous manner until it encounters an empty line or some other indicator that Mistral has finished responding.
• The process is repeated for each line in the file.
• Error output of the Mistral process is inherited directly by the Rust program, which allows any errors from the CLI to be printed directly to the console.

This approach assumes that Mistral sends some form of delimiter or signal indicating the end of its output for each input. If Mistral doesn't provide such a delimiter, you might need to implement a timeout or a specific logic to determine when to stop reading the output and proceed with the next input.
