Installation

This installation procedure assumes you are on a Linux system, using bash and have python3.8 installed.

Requirements

Git
Python 3.6 (or higher)
An Internet connection
A Telegram bot token (obtainable at @Botfather)
A payment provider token (obtainable by connecting a provider with your bot)

Consider renting a VPS to host the bot on; a cheap one should do, as greed is pretty lightweight! :)

Steps

Download the project files by running:

git clone https://github.com/Steffo99/greed.git

Enter the newly created folder:
```
cd greed
```
Create a new virtualenv:
```
python3.8 -m venv venv
```
Activate the virtualenv:
```
source venv/bin/activate
```
Install the project requirements:
```
pip install -r requirements.txt
```
Optional: For colored console output, install coloredlogs:
```
pip install coloredlogs
```
Generate the configuration file:
```
python -OO core.py
```
Edit the configuration file, adding your bot and payment tokens to it:
```
nano config/config.toml
```
(Press Ctrl+X and then two times Enter to save and quit nano.)
Optional: customize the files in the strings folder for custom messages.
Start the bot:
```
python -OO core.py
```
Open Telegram, and send a /start command to your bot to be automatically promoted to 💼 Manager.
Stop the bot by pressing Ctrl+C.

Running the bot

After the installation, to run the bot, you'll need to:

Activate the virtualenv (if it's not already activated in the current console session):
```
source venv/bin/activate
```
Start the bot:
```
python -OO core.py
```

Keep the bot running

If you want to keep the bot open even after you closed your terminal window, you'll need to use some external program.

Some of them are:

screen (easier, but doesn't restart automatically)
systemd (recommended, but more difficult)

`screen`

Open a screen that will be running the bot with the following command:
```
screen venv/bin/python -OO core.py
```
To safely detach the screen, press Ctrl+A and then Ctrl+D.

`systemd`

Assuming you downloaded greed in /srv/greed:

Create a new user named greed:
```
useradd greed --system
```
Give ownership of the greed folder you downloaded earlier to the greed user:
```
chown -R greed: /srv/greed
```

Create a new file in /etc/systemd/system named bot-greed.service with the following contents:

[Unit]
Name=bot-greed
Description=Greed Bot
Wants=network-online.target
After=network-online.target nss-lookup.target

[Service]
Type=exec
User=greed
WorkingDirectory=/srv/greed
ExecStart=/srv/greed/venv/bin/python -OO /srv/greed/core.py
Environment=PYTHONUNBUFFERED=1

[Install]
WantedBy=multi-user.target

Start the bot-greed service:
```
systemctl start bot-greed
```
If everything goes well, enable the bot-greed service, so it will automatically start on a reboot:
```
systemctl enable bot-greed   
```

Updating

To update the bot, run the following commands:

git stash
git pull
git stash pop

If you're using an older version of greed, you may need to recreate the configuration, as greed won't use config.ini anymore and will use config.toml instead.

Usage

All features can be accessed through the Telegram bot chat.

As a 💼 Manager, you can add new products, check the placed orders, create new transactions and generate .csv log files.
You can also add additional 💼 Managers.

Users will be able to add credit to their wallet, place orders and contact you in case they require assistance.

Documentation and help

If you find a bug, have an idea for a new feature or just require help with greed, please post an issue on GitHub, or, if GitHub is blocked in your country, join the Telegram group and send a message there.

If you can read Italian, you can try to read the paper I wrote about greed for my final High School exam.

If you are proficient in Python, you can also try reading the code. Most of the bot interactions can be found in the worker.py file, so try to have a look there.

Forks

Some people made a copy of Greed and added or changed some things to it (they made a fork).
These forks are listed below.

Please note that @Steffo99, the main developer of greed, does not endorse any of these forks.
Do not file bug reports here for bugs in a fork!
