GASh: Go Again Shell

There has certainly already been at least one shell written in go by now (source: it's 2019), so GASh seemed like an appropriate name for this.

Important Notes

• REGRESSIONS! This is version 0 of GASh, and therefore changes and regressions are expected to happen frequently.

• GASh, by design, is not a POSIX-compliant shell in its default configuration. However, making a POSIX-compliant GASh configuration is a long-term development goal.

When will the major version be changed?

Version 1.0.0

• Configuration for prompt
• Configuration for which console modules are used
• If a prompt writer takes too long, a fallback prompt will be displayed
• Pipes and redirects are fully supported
• Background tasks are fully supported
• GASh is stable enough for everyday use

Version 2.0.0

• Scriptable plugin system
• Ability to emulate other shells by replacing modules
• (not requited for 2.0.0 but...) Build-your-own-GASh tutorial exists

Version 3.0.0

• POSIX-compliant mode

What is a console module?

Features

Reminder to take a break

The shell could remind its user to take a break if it detects regular activity for a long period of time (ex: at least one command every 8 minutes for a period longer than half an hour). The shell would print "Take a break" after every command entered until the user types something like 5-more-minutes or taking-a-break-now. Also if the user types taking-a-break-now and then uses the shell within a short period of time, the shell should call its user a liar.

Internal Commands

Go Fish

Since the shell is written in Golang, it is only appropriate that an implementation of the classic game "Go Fish" should exist as an internal shell command.

gash-df command

An alternative to the df command with progress bars rendered for a visual representation of disk use. User could alias to df in their config if they find this particularly useful.

Standard Stuff

• Customizable prompt

  • Probably using the Go template package text/template

    For instance

    {{.User}}@{{.Host}}:{{.WorkingDirectory}}$
    

    to display

    username@hostname:~$
    

• Configuration in .config/gash-shell
  • Could either be TOML, YAML, or JSON(hacked to allow trailing commas)
