Setting up your instance
------------------------
Run :code:`redbot-setup` and follow the prompts. It will ask first for where you want to
store the data (the default is :code:`~/.local/share/Red-DiscordBot`) and will then ask
for confirmation of that selection. Next, it will ask you to choose your storage backend
(the default here is JSON). It will then ask for a name for your instance. This can be
anything as long as it does not contain spaces; however, keep in mind that this is the
name you will use to run your bot, and so it should be something you can remember.

Running Red
-----------
Run :code:`redbot <your instance name>` and run through the initial setup. This will ask for
your token and a prefix.

-------------------------------
Installing the pre-requirements
-------------------------------
Please install the pre-requirements using the commands listed for your operating system.
The pre-requirements are:
- Python 3.6 or greater
- pip 9.0 or greater
- git
- Java Runtime Environment 8 or later (for audio support)
~~~~~~~~~~
Arch Linux
~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~
Debian and Raspbian Stretch
~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. warning::
Audio will not work on Raspberry Pi's **below** 2B. This is a CPU problem and
*cannot* be fixed.
We recommend installing pyenv as a method of installing non-native versions of python on
Debian/Raspbian Stretch. This guide will tell you how. First, run the following commands:
.. code-block:: none
sudo apt install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev libffi-dev git unzip default-jre
curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer | bash
After that last command, you may see a warning about 'pyenv' not being in the load path. Follow the
instructions given to fix that, then close and reopen your shell.
Then run the following command:
.. code-block:: none
CONFIGURE_OPTS=--enable-optimizations pyenv install 3.7.0 -v
This may take a long time to complete.
After that is finished, run:
.. code-block:: none
pyenv global 3.7.0
Pyenv is now installed and your system should be configured to run Python 3.7.
~~~
Mac
~~~
Install Brew: in Finder or Spotlight, search for and open *Terminal*. In the terminal, paste the
following, then press Enter:
.. code-block:: none
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
After the installation, install the required packages by pasting the commands and pressing enter,
one-by-one:
.. code-block:: none
brew install python3 --with-brewed-openssl
brew install git
brew tap caskroom/versions
brew cask install java8
~~~~~~~~~~~~~~~~~~~~~~~~~~
Ubuntu 18.04 Bionic Beaver
~~~~~~~~~~~~~~~~~~~~~~~~~~
.. code-block:: none
sudo apt install python3.6-dev python3-pip build-essential libssl-dev libffi-dev git unzip default-jre -y
~~~~~~~~~~~~~~~~~~~~~~~~~
Ubuntu 16.04 Xenial Xerus
~~~~~~~~~~~~~~~~~~~~~~~~~
We recommend adding the ``deadsnakes`` apt repository to install Python 3.6 or greater:
.. code-block:: none
sudo apt install software-properties-common
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
Now, install python, pip, git and java with the following commands:
.. code-block:: none
sudo apt install python3.6-dev build-essential libssl-dev libffi-dev git unzip default-jre wget -y
wget https://bootstrap.pypa.io/get-pip.py
sudo python3.6 get-pip.py
------------------------------
Creating a Virtual Environment
------------------------------
We **strongly** recommend installing Red into a virtual environment. See the section
`installing-in-virtual-environment`.
.. _installing-red-linux-mac:
--------------
Installing Red
--------------
Choose one of the following commands to install Red.
.. note::
If you're not inside an activated virtual environment, include the ``--user`` flag with all
``pip3`` commands.
To install without audio support:
.. code-block:: none
pip3 install -U --process-dependency-links --no-cache-dir Red-DiscordBot
Or, to install with audio support:
.. code-block:: none
pip3 install -U --process-dependency-links --no-cache-dir Red-DiscordBot[voice]
Or, install with audio and MongoDB support:
.. code-block:: none
pip3 install -U --process-dependency-links --no-cache-dir Red-DiscordBot[voice,mongo]
.. note::
To install the development version, replace ``Red-DiscordBot`` in the above commands with the
following link:
.. code-block:: none
git+https://github.com/Cog-Creators/Red-DiscordBot@V3/develop#egg=Red-DiscordBot
--------------------------
Setting Up and Running Red
--------------------------
After installation, set up your instance with the following command:
.. code-block:: none
redbot-setup
This will set the location where data will be stored, as well as your
storage backend and the name of the instance (which will be used for
running the bot).
Once done setting up the instance, run the following command to run Red:
.. code-block:: none
redbot <your instance name>
It will walk through the initial setup, asking for your token and a prefix.
You may also run Red via the launcher, which allows you to restart the bot
from discord, and enable auto-restart. You may also update the bot from the
launcher menu. Use the following command to run the launcher:
.. code-block:: none
redbot-launcher

.. _installing-in-virtual-environment:
=======================================
Installing Red in a Virtual Environment
=======================================
Virtual environments allow you to isolate red's library dependencies, cog dependencies and python
binaries from the rest of your system. It is strongly recommended you use this if you use python
for more than just Red.
.. _using-venv:
--------------
Using ``venv``
--------------
This is the quickest way to get your virtual environment up and running, as `venv` is shipped with
python.
First, choose a directory where you would like to create your virtual environment. It's a good idea
to keep it in a location which is easy to type out the path to. From now, we'll call it
``path/to/venv/`` (or ``path\to\venv\`` on Windows).
~~~~~~~~~~~~~~~~~~~~~~~~
``venv`` on Linux or Mac
~~~~~~~~~~~~~~~~~~~~~~~~
Create your virtual environment with the following command::
python3 -m venv path/to/venv/
And activate it with the following command::
source path/to/venv/bin/activate
.. important::
You must activate the virtual environment with the above command every time you open a new
shell to run, install or update Red.
Continue reading `below <after-activating-virtual-environment>`.
~~~~~~~~~~~~~~~~~~~
``venv`` on Windows
~~~~~~~~~~~~~~~~~~~
Create your virtual environment with the following command::
python -m venv path\to\venv\
And activate it with the following command::
path\to\venv\Scripts\activate.bat
.. important::
You must activate the virtual environment with the above command every time you open a new
Command Prompt to run, install or update Red.
Continue reading `below <after-activating-virtual-environment>`.
.. _using-pyenv-virtualenv:
--------------------------
Using ``pyenv virtualenv``
--------------------------
.. note::
This is for non-Windows users only.
Using ``pyenv virtualenv`` saves you the headache of remembering where you installed your virtual
environments. If you haven't already, install pyenv with `pyenv-installer`_.
First, ensure your pyenv interpreter is set to python 3.6 or later with the following command::
pyenv version
Now, create a virtual environment with the following command::
pyenv virtualenv <name>
Replace ``<name>`` with whatever you like. If you forget what you named it, use the command ``pyenv
versions``.
Now activate your virtualenv with the following command::
pyenv shell <name>
.. important::
You must activate the virtual environment with the above command every time you open a new
shell to run, install or update Red.
Continue reading `below <after-activating-virtual-environment>`.
.. _pyenv-installer: https://github.com/pyenv/pyenv-installer/blob/master/README.rst
----
.. _after-activating-virtual-environment:
Once activated, your ``PATH`` environment variable will be modified to use the virtual
environment's python executables, as well as other executables like ``pip``.
From here, install Red using the commands listed on your installation guide (`Windows
<installing-red-windows>` or `Non-Windows <installing-red-linux-mac>`).
.. note::
The alternative to activating the virtual environment each time you open a new shell is to
provide the full path to the executable. This will automatically use the virtual environment's
python interpreter and installed libraries.
--------------------------------------------
Virtual Environments with Multiple Instances

If you are running multiple instances of Red on the same machine, you have the option of either
using the same virtual environment for all of them, or creating separate ones.
.. note::
This only applies for multiple instances of V3. If you are running a V2 instance as well,
You **must** use separate virtual environments.
The advantages of using a *single* virtual environment for all of your V3 instances are:
- When updating Red, you will only need to update it once for all instances (however you will still need to restart all instances for the changes to take effect)
- It will save space on your hard drive
On the other hand, you may wish to update each of your instances individually.
.. important::
Windows users with multiple instances should create *separate* virtual environments, as
updating multiple running instances at once is likely to cause errors.
