icat (image preview)

[Meaticus22]

Issue Description

I am attempting to create a custom plugin for xplr that integrates with icat (a command-line tool for displaying images in the terminal). Despite my efforts, I am encountering issues with key mapping and process execution. Specifically, when I press the designated key (i) to view an image, I receive a warning stating "key map not found." Additionally, I previously encountered an error with the process exiting with code 127, indicating that the command was not found.

Current Configuration

Below is the current state of my init.lua configuration file for xplr:

-- Define the version string
version = tostring(xplr.util.version().major) .. "." .. tostring(xplr.util.version().minor) .. "." .. tostring(xplr.util.version().patch)

-- Get the home directory
local home = os.getenv("HOME")

-- Update the package path to include custom plugins
package.path = home .. "/.config/xplr/plugins/?/init.lua;" .. home .. "/.config/xplr/plugins/?.lua;" .. package.path

-- Plugins

-- paste.rs.xplr
require("paste-rs").setup()

-- trash-cli.xplr
require("trash-cli").setup{
  -- Trash file(s)
  trash_bin = "trash-put",
  trash_mode = "delete",
  trash_key = "d",

  -- Empty trash
  empty_bin = "trash-empty",
  empty_mode = "delete",
  empty_key = "E",

  -- Interactive selector
  trash_list_bin = "trash-list",
  trash_list_selector = "fzf -m | cut -d' ' -f3-",

  -- Restore file(s)
  restore_bin = "trash-restore",

  -- Restore files deleted from $PWD only
  restore_mode = "delete",
  restore_key = "r",

  -- Restore files deleted globally
  global_restore_mode = "delete",
  global_restore_key = "R",
}

-- Type `dd` to trash, `dr` or `dR` to restore, and `dE` to empty trash.

-- Configure key binding to view images using the shell script
local xplr = xplr

xplr.config.modes.builtin.default.key_bindings.on_key.i = {
  help = "view image",
  messages = {
    {
      BashExecSilently = [===[
        ~/.config/xplr/view_image.sh "$XPLR_FOCUS_PATH"
      ]===]
    },
  },
}

Additional Context

I have created a shell script named view_image.sh to handle the image viewing process. The script is located in the ~/.config/xplr directory and is designed to ensure that kitten (the command-line tool that includes icat) is in the PATH and then execute kitten icat to display the image.

Here is the content of the view_image.sh script:

#!/bin/bash

# Ensure kitten is in the PATH
export PATH="/opt/homebrew/bin:$PATH"

# Check if the file exists and is an image
if [ -f "$1" ]; then
  kitten icat "$1"
else
  echo "File not found or not an image: $1"
fi

I am seeking assistance to resolve the issues with key mapping and process execution. Specifically, I need help to ensure that the key binding is correctly configured and that the shell script is executed without errors. Any guidance or suggestions on how to improve the integration of icat with xplr would be greatly appreciated.

Thank you for your time and consideration.
