MyCLI - A MySQL/MariaDB Client with Auto-completion and Syntax-highlighting

MyCLI is an easy-to-use command line (CLI) interface for the popular database management systems: MySQL, MariaDB, and Percona with auto-completion and syntax highlighting. It is built using prompt_toolkit and requires Python 2.7, 3.3, 3.4, 3.5, and 3.6. It supports secure connections over SSL to the MySQL server.

MyCLI Features

• When you first start it, a config file is automatically created at ~/.myclirc.
• Supports auto-completion while typing SQL keywords as well as tables, views and columns in the database.
• Also supports smart-completion which is enabled by default and will offer suggestions for context-sensitive completion.

For instance:

SELECT * FROM <Tab> - this will just show table names. 
SELECT * FROM users WHERE <Tab> - this will simply show column names. 

• Supports syntax highlighting using Pygments.
• Support for SSL connections.
• Offers support for multiline queries.
• It optionally logs every query and its output to a file (note that this is disabled by default).
• Allows you to save favorite queries (save a query using \fs alias and run it with \f alias).
• Supports timing of SQL statements and table rendering.
• Prints tabular data in an appealing way.
