remindrun 0.7.1

Run commands with Reminder monitoring and expose their status to the Android app.

Reminder

Reminder is a minimal prototype for monitoring Linux command runs from an Android app.

The first version has two parts:

• remindrun: a Python command wrapper. Put remindrun before a command to record its status, output tail, exit code, and timestamps.
• Android app: a small native app that polls the remindrun HTTP API, lists runs, and posts a local notification when a run changes from running to finished.

Python monitor

Install the local package in a virtual environment:

python3 -m venv .venv
.venv/bin/python -m pip install -e .

Or install the built wheel:

.venv/bin/python -m pip install dist/remindrun-0.7.1-py3-none-any.whl

Start the status server on the Linux machine:

remindrun server --host 0.0.0.0 --port 8765 --token change-this-token

Run commands through Reminder:

remindrun sleep 5
remindrun run -- bash -lc 'echo hello && sleep 2 && echo done'
remindrun status

You can use the shorter rrun command for the same actions:

rrun sleep 5
rrun ngrok --domain <YOUR_DEV_DOMAIN>.ngrok-free.dev

The server exposes:

• GET /health
• GET /api/runs?limit=50
• GET /api/runs/{id}
• GET /api/events?since=<updatedAt>

By default the SQLite database lives at ~/.reminder/reminder.db. Set REMINDER_HOME=/path/to/dir to change that location.

Public access

If you do not have a public IP, use a Cloudflare quick tunnel:

remindrun public

This starts the local server and runs cloudflared tunnel --url http://127.0.0.1:8765. It prints a public https://*.trycloudflare.com URL and a token. Enter both in the Android app:

Server: https://example.trycloudflare.com
Token:  generated-token

If cloudflared is missing, install it first:

brew install cloudflared

Cloudflare quick tunnel URLs are random. If you need the same URL every time and do not own a domain, use ngrok's free Dev Domain:

brew install ngrok/ngrok/ngrok
ngrok config add-authtoken <YOUR_NGROK_AUTHTOKEN>
remindrun ngrok --domain <YOUR_DEV_DOMAIN>.ngrok-free.dev

In the Android app:

Server: https://<YOUR_DEV_DOMAIN>.ngrok-free.dev
Token:  generated-token

If the Android app needs to connect to a server that already has a public IP or a public domain:

remindrun server --host 0.0.0.0 --port 8765 --token a-long-random-token

Then open TCP port 8765 in the cloud security group or firewall.

In the Android app:

Server: http://<public-ip>:8765
Token:  a-long-random-token

For real public use, prefer HTTPS through a reverse proxy or tunnel. Plain http://<public-ip>:8765 works for testing, but the token can be observed on an untrusted network.

Android app

Open the android/ directory in Android Studio.

For an emulator, the default server URL is:

http://10.0.2.2:8765

For a physical phone, start the server with --host 0.0.0.0, put the phone on the same network, then set the app server URL to:

http://<linux-machine-ip>:8765

If the server was started with --token, enter the same token in the app's Token field.

Tap Save to lock the Server and Token fields. Tap Unlock before editing them again.

Tap Delete on a run in the history list to delete it from the server.

Tap a run, or tap Console, to open the run's terminal output. Use Back to return to the main list.

This prototype polls every 5 seconds while the app process is alive. A later version should move polling into a foreground service or push channel if you want reliable notifications while the app is fully backgrounded.
