sailor-remote-agent 0.1.1

Exam evaluation and answer display system with SSH verification

Remote Agent

A minimal Python web app + API built with Bottle for clipboard operations and safe expression evaluation.

Features

• GET /ping - Health check endpoint returning {pong: "ok"}
• POST /clipboard - Accepts JSON with content field, stores in memory, and executes xclip command
• POST /evaluate - Safely evaluates Python literals using ast.literal_eval and stores results
• GET /answer - Renders HTML showing the latest evaluation result
• GET /result - Renders HTML showing all evaluation results

Installation

Development Installation

1. Install dependencies:

pip install bottle

2. Run the app directly:

python app.py

Package Installation

1. Build the package:

pip install build
python -m build

This will create dist/remote-agent-0.1.0.tar.gz and wheel files.

2. Install locally:

pip install dist/remote-agent-0.1.0*.whl

3. Run using the console script:

remote-agent

The app will start on http://localhost:8080

Publishing to PyPI

Prerequisites

1. Create accounts:

   • PyPI account: https://pypi.org/account/register/
   • TestPyPI account: https://test.pypi.org/account/register/

2. Install required tools:

pip install build twine

Build and Upload Steps

1. Update version in pyproject.toml if needed:

version = "0.1.0"

2. Build the package:

python -m build

This creates:

• dist/remote-agent-0.1.0.tar.gz (source distribution)
• dist/remote-agent-0.1.0-py3-none-any.whl (wheel)

3. Test on TestPyPI first (recommended):

twine upload --repository testpypi dist/*

You'll be prompted for:

• Username: your TestPyPI username
• Password: your TestPyPI API token (create at https://test.pypi.org/manage/account/token/)

4. Test installation from TestPyPI:

pip install --index-url https://test.pypi.org/simple/ remote-agent

5. Upload to PyPI (production):

twine upload dist/*

You'll be prompted for:

• Username: __token__
• Password: your PyPI API token (create at https://pypi.org/manage/account/token/)

6. Verify installation:

pip install remote-agent
remote-agent

API Usage Examples

Health Check

curl http://localhost:8080/ping
# Response: {"pong": "ok"}

Clipboard Operation

curl -X POST http://localhost:8080/clipboard \
  -H "Content-Type: application/json" \
  -d '{"content": "Hello World"}'
# Response: {"status": "ok"}

Evaluate Expression

curl -X POST http://localhost:8080/evaluate \
  -H "Content-Type: application/json" \
  -d '{"expr": "[1, 2, 3]"}'
# Response: {"status": "ok", "result": [1, 2, 3]}

View Results

• Open http://localhost:8080/answer in browser (latest result)
• Open http://localhost:8080/result in browser (all results)

Notes

• Storage is in-memory (data is lost on restart)
• Evaluation uses ast.literal_eval for safety (only Python literals, no code execution)
• Clipboard command requires xclip to be installed on the system
• The app runs on localhost:8080 by default

Requirements

• Python 3.7+
• Bottle (only dependency)
• xclip (for clipboard functionality on Linux)
