Quick Start
|
|
-----------
|
|
|
|
If you already know how to install python packages, then you can simply do:
|
|
|
|
::
|
|
|
|
$ pip install -U pgcli
|
|
|
|
or
|
|
|
|
$ brew install pgcli # Only on macOS
|
|
|
|
If you don't know how to install python packages, please check the
|
|
`detailed instructions`__.

|
|
|
|
Usage
|
|
-----
|
|
|
|
::
|
|
|
|
$ pgcli [database_name]
|
|
|
|
or
|
|
|
|
$ pgcli postgresql://[user[:password]@][netloc][:port][/dbname]
|
|
|
|
Examples:
|
|
|
|
::
|
|
|
|
$ pgcli local_database
|
|
|
|
$ pgcli postgres://amjith:pa$$w0rd@example.com:5432/app_db
|
|
|
|
Features
|
|
--------
|
|
|
|
The `pgcli` 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.
|
|
Note: `pgcli` uses the `tabulate`_ package to pretty-print tables. This library does smart formatting
|
|
of numbers, which can sometimes lead to unexpected output. See `this issue`_ for more details.

Config
|
|
------
|
|
A config file is automatically created at ``~/.config/pgcli/config`` at first launch.
|

Detailed Installation Instructions:
|
|
-----------------------------------
|
|
|
|
macOS:
|
|
======
|
|
|
|
The easiest way to install pgcli is using Homebrew.
|
|
|
|
::
|
|
|
|
$ brew install pgcli
|
|
|
|
Done!
|
|
|
|
Alternatively, you can install ``pgcli`` 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 pgcli
|
|
|
|
If that fails due to permission issues, you might need to run the command with
|
|
sudo permissions.
|
|
|
|
::
|
|
|
|
$ sudo pip install pgcli
|
|
|
|
If pip is not installed check if easy_install is available on the system.
|
|
|
|
::
|
|
|
|
$ which easy_install
|
|
|
|
$ sudo easy_install pgcli
|
|
|
|
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
|
|
|
|
``pgcli`` 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 pgcli:
|
|
|
|
::
|
|
|
|
$ sudo pip install pgcli
|
|
|
|
|
|
Docker
|
|
======
|
|
|
|
Pgcli can be run from within Docker. This can be useful to try pgcli without
|
|
installing it, or any dependencies, system-wide.
|
|
|
|
To build the image:
|
|
|
|
::
|
|
|
|
$ docker build -t pgcli .
|
|
|
|
To create a container from the image:
|
|
|
|
::
|
|
|
|
$ docker run --rm -ti pgcli pgcli <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 pgcli pgcli -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 pgcli pgcli foo
|
|

creating `Python Prompt Toolkit <http://github.com/jonathanslenders/python-prompt-toolkit>`_,
|
|
which is quite literally the backbone library, that made this app possible.
|
|
Jonathan has also provided valuable feedback and support during the development
|
|
of this app.

Thanks to `psycopg <http://initd.org/psycopg/>`_ for providing a rock solid

|
interface to Postgres database.
