Verano

Package to manage activities in a project. This project is inspired by the 'Primavera' or P6 software (Spring in Spanish), hence the name 'Verano' (Summer in Spanish).

Motivation

• Understand how P6 works under the hood.
• Adding activities one by one in P6 is quite time consuming.
• Provide a Free and Open Source Alternative to P6.
• Enhance my Go coding skills.

Installation

# inside a Go module, execute the following command:
$ go get github.com/vanillaiice/verano

Features

• Sort activities in a project based on their relationships (only start to finish relationships supported for now).
• Compute the start and finish times of all activities.
• Render a graph (with graphviz) image file showing the activities and their relationships.
• Parse and process lists of activities in JSON, CSV, and XLSX formats
• Storage of the activities in a SQLite database.

Please check the 'examples' directory in this repo to see these features in action.

Structure of an Activity

For reference, here is the data structure of activities used by this package:

type Activity struct {
	Id             int           // Unique identifier of the activity
	Description    string        // description of the activity
	Duration       time.Duration // duration of the activity
	Start          time.Time     // Start time of the activity
	Finish         time.Time     // Finish time of he activity
	PredecessorsId []int         // ID of the activities that precede
	SuccessorsId   []int         // ID of the activities that come after
	Cost           float64       // Cost of the activity
}
