A REPL for Postgres

This is a postgres client that does auto-completion and syntax highlighting.

Quick Start

If you already know how to install python packages, then you can simply do:

$ pip install pgcli

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:[email protected]:5432/app_db

Features

The pgcli is written using prompt_toolkit.

• Auto-completion 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.

• Config file is automatically created at ~/.pglirc at first launch.

• Primitive support for psql back-slash commands.

• Pretty prints tabular data.

Contributions:

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:

OS X:

For installing Python packages it is recommended to use the package manager called pip. Check if pip is installed on the system.

$ 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:

Check if pip is already available in your system.

$ which pip

If it does then install pgcli using the pip command as follows:

$ sudo pip install pgcli

If it doesn't exist, use your linux package manager to install pip. This might look something like:

$ sudo apt-get install python-pip

or

$ sudo yum install python-pip

Then you can install pgcli:

$ sudo pip install pgcli

Thanks:

A special thanks to Jonathan Slenders for creating 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.

This app includes the awesome tabulate library for pretty printing the output of tables. The reason for vendoring this library rather than listing it as a dependency in setup.py, is because I had to make a change to the table format which is merged back into the original repo, but not yet released inPyPI.

Click is used for command line option parsing and printing error messages.

Thanks to psycopg for providing a rock solid interface to Postgres database.

Thanks to all the beta testers and contributors for your time and patience. :)
