Description: A REPL for the Materialize Streaming Database Engine
        ----------------------------------------------------
        
        See https://materialize.io for an introduction to Materialize.
        
        Quick Start
        -----------
        
        The easiest way to get started with ``mzcli`` with a remote materialized is to use docker::
        
            docker run -it materialize/mzcli --help
        
        This is a work-in-progress materialize client that does auto-completion and
        syntax highlighting. It is a soft fork of `mzcli`, and will hopefully one day be
        even less of a fork from mzcli, but due to materialize's extra functionality
        this will be a long-lived tool for interacting with ``materialized``.

        .. _environment variables: https://www.postgresql.org/docs/current/libpq-envars.html
        
        Features
        --------
        
        The ``mzcli`` is written using prompt_toolkit_.
        
        * Auto-completes as you type for SQL keywords as well as tables and
          columns in the database.
        * Syntax highlighting using Pygments.
        * Smart-completion (enabled by default) will suggest context-sensitive
          completion.
        
            - ``SELECT * FROM <tab>`` will only show table names.
            - ``SELECT * FROM users WHERE <tab>`` will only show column names.
        
        * Primitive support for ``psql`` back-slash commands.
        * Pretty prints tabular data.
        
        .. _prompt_toolkit: https://github.com/jonathanslenders/python-prompt-toolkit
        .. _tabulate: https://pypi.python.org/pypi/tabulate
        
        Config
        ------
        
        A config file is automatically created at ``~/.config/mzcli/config`` at first launch.
        See the file itself for a description of all available options.
        
        Contributions:
        --------------
        
        While we are not mzcli, the following documentation expresses our sentiments
        and still correctly represents the development workflow.
        
        If you're interested in contributing to this project, first of all I would like
        to extend my heartfelt gratitude. I've written a small doc to describe how to
        get this running in a development setup.

          Detailed Installation Instructions:
          -----------------------------------
        
          macOS:
          ======
        
          The easiest way to install mzcli is using Homebrew.
        
          ::
        
              $ brew install mzcli
        
          Done!
        
          Alternatively, you can install ``mzcli`` as a python package using a package
          manager called called ``pip``. You will need postgres installed on your system
          for this to work.
        
          In depth getting started guide for ``pip`` - https://pip.pypa.io/en/latest/installing.html.
        
          ::
        
              $ which pip
        
          If it is installed then you can do:
        
          ::
        
              $ pip install mzcli
        
          If that fails due to permission issues, you might need to run the command with
          sudo permissions.
        
          ::
        
              $ sudo pip install mzcli
        
          If pip is not installed check if easy_install is available on the system.
        
          ::
        
              $ which easy_install
        
              $ sudo easy_install mzcli
        
          Linux:
          ======
        
          In depth getting started guide for ``pip`` - https://pip.pypa.io/en/latest/installing.html.
        
          Check if pip is already available in your system.
        
          ::
        
              $ which pip
        
          If it doesn't exist, use your linux package manager to install `pip`. This
          might look something like:
        
          ::
        
              $ sudo apt-get install python-pip   # Debian, Ubuntu, Mint etc
        
              or
        
              $ sudo yum install python-pip  # RHEL, Centos, Fedora etc
        
          ``mzcli`` requires python-dev, libpq-dev and libevent-dev packages. You can
          install these via your operating system package manager.
        
        
          ::
        
              $ sudo apt-get install python-dev libpq-dev libevent-dev
        
              or
        
              $ sudo yum install python-devel postgresql-devel
        
          Then you can install mzcli:
        
          ::
        
              $ sudo pip install mzcli
        
          mzcli only runs on Python3.6+.
        
        
          Docker
          ======
        
          Pgcli can be run from within Docker. This can be useful to try mzcli without
          installing it, or any dependencies, system-wide.
        
          To build the image:
        
          ::
        
              $ docker build -t mzcli .
        
          To create a container from the image:
        
          ::
        
              $ docker run --rm -ti mzcli mzcli <ARGS>
        
          To access postgresql databases listening on localhost, make sure to run the
          docker in "host net mode". E.g. to access a database called "foo" on the
          postgresql server running on localhost:5432 (the standard port):
        
          ::
        
              $ docker run --rm -ti --net host mzcli mzcli -h localhost foo
        
          To connect to a locally running instance over a unix socket, bind the socket to
          the docker container:
        
          ::
        
              $ docker run --rm -ti -v /var/run/postgres:/var/run/postgres mzcli mzcli foo
        
        
          IPython
          =======
        
          Pgcli can be run from within `IPython <https://ipython.org>`_ console. When working on a query,
          it may be useful to drop into a mzcli session without leaving the IPython console, iterate on a
          query, then quit mzcli to find the query results in your IPython workspace.
        
          Assuming you have IPython installed:
        
          ::
        
              $ pip install ipython-sql
        
          After that, run ipython and load the ``mzcli.magic`` extension:
        
          ::
        
              $ ipython
        
              In [1]: %load_ext mzcli.magic
        
        
          Connect to a database and construct a query:
        
          ::
        
              In [2]: %mzcli postgres://someone@localhost:5432/world
              Connected: someone@world
              someone@localhost:world> select * from city c where countrycode = 'USA' and population > 1000000;
