Create install and launch scripts for: GNU Emacs Target OS: linux App metadata: {"id": "emacs", "name": "GNU Emacs", "description": "An extensible, customizable, self-documenting real-time display editor with over 10,000 built-in commands. GNU Emacs is one of the oldest free and open source projects still under active development, featuring powerful automation capabilities through macros and Lisp scripting.", "website": "https://www.gnu.org/software/emacs", "icon_url": "https://www.gnu.org/software/emacs/images/emacs.png", "categories": ["Code Editor", "Text Editor"], "tags": ["GNU", "GPL", "Extensible", "Lisp", "Free Software", "Cross-Platform", "Customizable"], "os_support": ["linux", "windows", "macos"], "requires_payment": false, "foss": true, "gh_repo": "git://git.sv.gnu.org/emacs.git", "self_hostable": true, "requires_hardware": false, "package_managers": {"apt": "emacs", "snap": "emacs", "flatpak": "org.gnu.emacs", "brew": "emacs", "choco": "emacs", "winget": "GNU.Emacs"}, "download_url": "https://www.gnu.org/software/emacs/download.html"}

Research the official install method, create scripts, test them in a sandbox, LAUNCH the app, take a screenshot showing it running, and submit your result. The submit_result tool will verify the screenshot — if the app isn't visibly open it will reject and you must keep trying. Remember to delete the sandbox when done.

Thinking

Alright, let me break down what I need to do:

  1. Create install and launch scripts for GNU Emacs on Linux
  2. Test them in a sandbox VM
  3. Launch the app and take a screenshot
  4. Extract metadata (binary path, display name, version, etc.)
  5. Submit the result

The metadata provided says: - Package managers available: apt, snap, flatpak, brew, choco, winget - For Linux (apt is the standard), the package is "emacs" - It's free and open source - No payment required

Let me start by: 1. Creating a sandbox (Linux) 2. Writing an install script (using apt) 3. Running the install script 4. Writing a launch script 5. Launching the app 6. Taking a screenshot 7. Writing and running an extract_metadata script 8. Submitting the result 9. Deleting the sandbox

Since I have no direct shell access, I must use the sandbox tools. Let me start by creating a sandbox for Linux.

I'll help you create install and launch scripts for GNU Emacs on Linux. Let me start by researching the official installation method and then setting up a sandbox to test it.

WebFetch
{
  "url": "https://www.gnu.org/software/emacs/download.html",
  "prompt": "What is the recommended installation method for GNU Emacs on Linux?"
}
ECONNREFUSED

I'll proceed with the standard apt-based installation method for Linux. Let me create a sandbox and set up the scripts.

mcp__sandbox__create_sandbox
{
  "os": "linux"
}
OK: sandbox 'linux-7c550944' created (os=linux). Use this name with other sandbox tools.

Now let me create the install script for GNU Emacs:

mcp__sandbox__sandbox_write
{
  "name": "linux-7c550944",
  "path": "/tmp/install_emacs.sh",
  "content": "#!/bin/bash\n# Install script for GNU Emacs on Linux\nset -e\n\necho \"Installing GNU Emacs...\"\n\n# Update package manager cache\napt-get update -qq\n\n# Install Emacs (includes GTK support for GUI)\napt-get install -y emacs\n\necho \"✓ GNU Emacs installed successfully\"\n"
}
OK: wrote 258 bytes to /tmp/install_emacs.sh

Now let me run the install script:

mcp__sandbox__sandbox_run
{
  "name": "linux-7c550944",
  "command": "bash /tmp/install_emacs.sh",
  "timeout": 120
}
EXIT CODE: 100

STDOUT:
Installing GNU Emacs...


STDERR:
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)
E: Unable to lock directory /var/lib/apt/lists/

I need to use sudo for apt. Let me update the install script:

mcp__sandbox__sandbox_write
{
  "name": "linux-7c550944",
  "path": "/tmp/install_emacs.sh",
  "content": "#!/bin/bash\n# Install script for GNU Emacs on Linux\nset -e\n\necho \"Installing GNU Emacs...\"\n\n# Update package manager cache\nsudo apt-get update -qq\n\n# Install Emacs (includes GTK support for GUI)\nsudo apt-get install -y emacs\n\necho \"✓ GNU Emacs installed successfully\"\n"
}
OK: wrote 268 bytes to /tmp/install_emacs.sh

The user wants me to create install and launch scripts for GNU Emacs on Linux. I'm in the middle of testing the installation. Let me continue with the installation process. I should track this with a todo list since this is a multi-step task.

Let me create a todo list to track progress: 1. Create and test install script 2. Create launch script 3. Run the launch script to start Emacs 4. Take a screenshot 5. Extract metadata 6. Submit results

Let me start by updating the todo list and continuing with the installation.

Task List
  • Create and test install script for GNU Emacs
  • Create launch script
  • Run launch script and verify Emacs starts
  • Take screenshot of running Emacs
  • Create and run extract_metadata script
  • Submit results
Todos have been modified successfully. Ensure that you continue to use the todo list to track your progress. Please proceed with the current tasks if applicable

Now let me run the install script with sudo:

{
  "name": "linux-7c550944",
  "command": "bash /tmp/install_emacs.sh",
  "timeout": 120

Great! Installation was successful. Now let me update the todo and create the launch script:

Now let me create the launch script:

}

Now let me run the launch script:

}
ERROR: command timed out after 30s

The launch script is hanging because it's launching Emacs in the background. Let me create a better version that runs Emacs and then takes a screenshot:

mcp__sandbox__sandbox_write
{
  "name": "linux-7c550944",
  "path": "/tmp/launch_emacs.sh",
  "content": "#!/bin/bash\n# Launch script for GNU Emacs on Linux\n\n# Launch Emacs in GUI mode\nemacs &\nEMACS_PID=$!\n\n# Give Emacs time to start up and render\nsleep 5\n\n# Check if process is still running\nif ps -p $EMACS_PID > /dev/null; then\n    echo \"✓ Emacs started successfully with PID $EMACS_PID\"\nelse\n    echo \"✗ Emacs failed to start\"\n    exit 1\nfi\n"
}
OK: wrote 339 bytes to /tmp/launch_emacs.sh
mcp__sandbox__sandbox_run
{
  "name": "linux-7c550944",
  "command": "bash /tmp/launch_emacs.sh 2>&1 &\nsleep 6\n",
  "timeout": 15
}
ERROR: command timed out after 15s

Let me try a simpler approach - just launch it directly without waiting for it:

mcp__sandbox__sandbox_run
{
  "name": "linux-7c550944",
  "command": "emacs &\nsleep 4\nps aux | grep emacs | grep -v grep",
  "timeout": 15
}
ERROR: command timed out after 15s

It seems the emacs command is blocking. Let me try with nohup:

mcp__sandbox__sandbox_run
{
  "name": "linux-7c550944",
  "command": "nohup emacs > /tmp/emacs.log 2>&1 &\necho $! > /tmp/emacs.pid\nsleep 3\ncat /tmp/emacs.pid",
  "timeout": 15
}
ERROR: command timed out after 15s

It looks like even simple commands are timing out. Let me check if the display is set up:

mcp__sandbox__sandbox_run
{
  "name": "linux-7c550944",
  "command": "echo $DISPLAY",
  "timeout": 5
}
EXIT CODE: 0

STDOUT:
:1


STDERR:
Thinking

The display is set, so we have a graphical environment available. Let me try to launch emacs with a timeout approach - starting it in the background properly. The issue might be that emacs is somehow waiting for input. Let me try using bash's job control differently.

Actually, I think the issue is that when I run emacs & in the sandbox_run command, it's still blocking because the command as a whole waits for background jobs to complete. I need to make sure to detach it properly.

Let me try a different approach - create a script that uses setsid or disown to properly detach the process.

Good, the display is available. Let me try a different approach to properly launch Emacs in the background:

mcp__sandbox__sandbox_run
{
  "name": "linux-7c550944",
  "command": "DISPLAY=:1 emacs &\ndisown\nsleep 2\necho \"Done\"",
  "timeout": 10
}
ERROR: command timed out after 10s

The shell seems to be waiting. Let me try a different strategy - write a Python script to launch it:

mcp__sandbox__sandbox_write
{
  "name": "linux-7c550944",
  "path": "/tmp/launch.py",
  "content": "#!/usr/bin/env python3\nimport subprocess\nimport os\nimport time\n\nos.environ['DISPLAY'] = ':1'\n\n# Launch Emacs in background\nproc = subprocess.Popen(['emacs'], stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL)\nprint(f\"Emacs started with PID: {proc.pid}\")\n\n# Wait a moment for it to render\ntime.sleep(3)\n\nprint(\"Done\")\n"
}

CRITERIA NOT MET:
  - extract_metadata_script: FAIL: "display_name" is hardcoded as "GNU Emacs" instead of being extracted from the Desktop Entry file (e.g., `grep "^Name=" "$DESKTOP_FILE"`), and should also fall back to package manager metadata via `dpkg -L emacs | grep -i description` or `rpm -q --queryformat='%{SUMMARY}\n' emacs`.

Fix the issues above, then call submit_result again.

I need to fix the extract_metadata script to properly extract the display_name. Let me update it:
