The Shell is a software program that runs in the terminal (i.e., a command line interpreter). Shells are import pieces of software as they allow users to access parts of the OS with command. Naturally, a file in the path could be run to achieve the same result but when using a shell, parts of the individual parts of the shell may be untied in some way to work together.
This project teaches you about creating shells where system commands and your own functions are integrated into one user experience. Cool, right?
In this (on going) project, Dabble is a shell to demonstrate how a common shell might work. In addition, the code allows for functions to be shared between commands.
To run Dabble, you must have Go (also called "Golang") installed. Dabble was created on a MacOS with Go version go1.13.5 darwin/amd64
To run: go run dabble.go
And you will see the following,
go run dabble.go

Check back often to see the evolution of the project!! This is a work-in-progress. I will continue to update the repository with updates. If you would like to contribute to this project, then please do! For instance, if you see some low-hanging fruit or task that you could easily complete, that could add value to the project, then I would love to have your insight.
Otherwise, please create an Issue for bugs or errors. Since I am a teaching faculty member at Allegheny College, I may not have all the time necessary to quickly fix the bugs and so I would be very happy to have any help that I can get from the OpenSource community for any technological insight. Much thanks in advance. I hope that this project helps you learn Go, or can be used in some other way that would be of help. :-)
