# RhinoReminds

> An XMPP reminder bot written in C#.

I've blogged about this project here: [RhinoReminds: An XMPP reminder bot for my convenience](https://starbeamrainbowlabs.com/blog/article.php?article=posts/328-RhinoReminds.html)

## Getting Started

### Downloading Prebuilt Binaries
Prebuilt binaries for the latest release are available on the [releases page](https://git.starbeamrainbowlabs.com/sbrl/RhinoReminds/releases).

### Building from Source

1. Install the NuGet dependencies:

```bash
nuget restore
```

2. Build the solution:

```bash
msbuild
```

3. Specify the environment variables

Variable		| Meaning
----------------|------------------------
`XMPP_JID`		| The JID to connect with
`XMPP_PASSWORD`	| The password to use when connecting

4. Execute the program

```bash
cd RhinoReminds/bin/{Debug|Release}
# Linux:
mono [--debug] RhinoReminds.exe [--help]
# Windows:
RhinoReminds.exe [--help]
```

### Setting up RhinoReminds as a system service
Some helpful template files are located in this repository to aid in setting _RhinoReminds_ up as a system service.

 - [`start_service.sh`](https://git.starbeamrainbowlabs.com/sbrl/RhinoReminds/src/branch/master/start_service.sh) Contains a script that reads in CLI variables from a file, sets up a PID file directory with the appropriate permissions, and then executes _RhinoReminds_ as an unprivileged user.
 - [`rhinoreminds.service`](https://git.starbeamrainbowlabs.com/sbrl/RhinoReminds/src/branch/master/rhinoreminds.service) Contains a systemd service file compatible with `start_service.sh`
 - [`rhinoreminds-rsyslog.conf`](https://git.starbeamrainbowlabs.com/sbrl/RhinoReminds/src/branch/master/rhinoreminds-rsyslog.conf) Contains an Rsyslog definition file compatible with the systemd service file defined above. When put in `/etc/rsyslog.d` (don't forget to restart the `rsyslog` service!), it will write and auto-rotate log files of the standard output and standard error of the main _RhinoReminds_ process to a subfolder fo `/var/log` automatically.


## Usage
The bot operates on natural language instructions. It picks what to do from the first word in the sentence, but the rest is parsed via AI.

### Setting a reminder

```
Remind me to feed the cat at 6pm
Remind me about CrossCode's release on 20th September 2018
Remind me to water the greenhouse tomorrow at 4:03pm
Remind me in 1 hour to check the oven
```

### Listing reminders

```
List all reminders
