Corty
1. Introduction
The development of Corty has been mainly in Fedora Linux.
It aims to be simple, and easy to use. It is a CLI application, and supports command auto-completion, colour-coded outputs etc.
2. How does Corty work?
Corty has a client-server architecture that communicates through a GraphQL API interface.
The user interacts with the server through the Corty CLI, which is a REPL interface that waits for user input.
A help is printed each time Corty starts. This helps the user with a quick overview of the primary commands available.
Command auto-completion is supported, and a TAB press cycles through each primary. The Enter key selects the command. Once the primary command is selected, a second TAB lists the secondary level of commands specific to the selected primary.
The server uses MongoDB as its database backend. While starting up, the client ensures that it has a proper connection to the server, as well as the MongoDB database. The connection is regularly checked through a heart-beat signal.
3. Installation
Corty requires the following packages.
- MongoDB
- python3-colorama
- python3-prompt-toolkit
- python3-pymongo
- python3-graphql-server
- python3-graphene
- graphql
MongoDB has to be running on localhost (for now), listening on the default port 27017. Splitting the database off, is something that should happen later.
Install MongoDB from their opensource release page. Other distributions may refer their mode of package installation.
# sudo dnf install mongodb-server -y
# sudo systemctl start mongod
# sudo systemctl status mongod
