g2h

Is kind of graph viewer in a terminal.

Get started

Nowadays, when have been developed a cli prompt part, g2h works with stdin as a major input system. The project was started developing with such a representation of graph as this one. You can find how to create it at the simple graph example.

A few time after was begun developing matrix type. Which supports path find algorithm, currently only Dijkstra's. You can find this example at the example section.

Commands

type	command	effect
	print	print, graph which was built
edge	add	get message and place it as a new edge
edge	connect	takes 2 parametes, indexes which edges we whant to have connected
matrix		takes 2 parametes size of matrix, width and hight
matrix	search	takes 2 parametes, start point and end point
matrix	block	takes index of node which is removed all links
settings	gap edge	takes size of gap between edges
settings	gap verticales	takes size of gap between connection lines

Examples

The examples might be a bit outdated.

Simple graph

>>> edge add hello
>>> edge add world
>>> edge add g2h
>>> edge add macha
>>> edge add andrey
>>> edge add vadim
>>> edge connect 0 1
>>> edge connect 0 2
>>> edge connect 2 0
>>> edge connect 3 4
>>> edge connect 3 5 
>>> edge connect 5 0
>>> print

Simple matrix

>>> matrix init 10 10              
>>> matrix search 65 99

Roadmap

• An another type of view
• Support a way to add a further nodes at the edges of matrix
• Mark blocked nodes(What exactly is a blocked node?)
• Switch between views
• Draw verticales below nodes list
• Support more then len(node_data) connections on node, encrese it's scope
• A Dinamic setting on space on connection
• CLI Promt
• Support a history of commands(Up/Down buttons as press buttons actions)
• Find a path on the graph
• Create a further bunch of search algorithms
• Connector types (for related graphs)
• Refactoring print method
• Refactoring of handling method
• Refactoring
