Inline Previews

[MillerApps]

It seems the inline image previews rely solely on Kitty being installed for Ghostty and Konsole. However, I think it is best to use the built-in support for the Kitty image protocol, at least in the case of Ghostty. A basic implementation would be something like:

package utils

import (
	"encoding/base64"
	"fmt"
	"io"
	"os"
)

// SendKittyImg sends a file as a Kitty protocol inline image without any extra output.
// The escape sequence is formatted per the spec: begins with ESC _ G, parameters terminated with a semicolon,
// then the base64 data, and finally terminated with ESC \.
func SendKittyImg(filePath string) error {
	// Open the file.
	f, err := os.Open(filePath)
	if err != nil {
		return err
	}
	defer f.Close()

	// Begin the inline image sequence
	fmt.Printf("\x1b_Gf=100,a=T;")
	
	// Base64-encode the file contents directly to stdout.
	encoder := base64.NewEncoder(base64.StdEncoding, os.Stdout)
	if _, err := io.Copy(encoder, f); err != nil {
		return err
	}
	encoder.Close()

	// Terminate the escape sequence
	fmt.Printf("\x1b\\\n")
	return nil
}

func IsGhosttyTerminalRunning() bool {

	terminal := os.Getenv("TERM")

    if strings.Contains(terminal, "ghostty") {
        return true
    }

	return false
}

The issue I ran into is this only works on gowall -w something breaks when modifying an image then trying to the same code does nothing, unlike with kitten icat. I'd be willing to work on this when I have time unless you already know what I am missing.

Hello @MillerApps ,

By all means, if you're interested in working on it, go for it, it would be great because i'm also not that keen on relying on kitten icat for other terminals.

Right now i'm focused on fixing bugs , polishing and refactoring gowall as you can see from the latest commits so i can't really invest much time for this enhancement. After refactoring i have to plan to add the main big features for the next release too.

@Achno I'll take it on and see if I can figure it out. No idea on a timeline but I have a starting point.

@MillerApps

No worries and above all no pressure :)

@Achno Definitely a good way to learn something new.
