Envo

A command-line environment variable manager for the current shell session. It works with bash and Windows cmd.

Envo offers several commands to view and change environment variables and also to execute simple scripts composed of those commands, thus allowing the same script for a particular env-var configuration on all supported platforms.

Envo is still an alpha version. Not all features are complete and not everything is thoroughly tested.

Features

A screenshot of envo path which displays the path in a "pretty" way. Note the tags, D for an entry which is duplicated, and N for an entry which is a non-existing path

Use envo with envo <command> <args> in your terminal

Commands

These are select envo commands. For a full list, check the command reference

show <name> ... - show values of environment variables in a "pretty" format
set <name> = [<value>] - set a value to an environment variable
unset <name> ... - unset (delete) an environment variabls
list <name> add <value> - add an element to an list environment variable (such as PATH)
clean <name> - cleans environment variables. Unsets empty strings, non-existing paths, empty lists. Removes duplicates from lists and non-existing paths from path lists.
run <script> - runs a simple script of commands. See the script reference on how to write scripts

Installation

You need a Ruby interpeter version 2.5 or higher
- To check, type ruby --version in your terminal
Install the ruby gem

$ gem install envo

Install the envo command

$ envo-install

If you're using bash, after the last step you'll need to either restart the session, or source the file in which envo was installed (it will be logged after the installation)

After this you can type

$ envo --help

... and see the commands and options supported by envo in your terminal.

Contributing

Issues and pull requests are welcome.

Part of why I created this tool was to refresh my ruby-foo. I hadn't done much ruby programming for years before this. Because of this, envo is not great (not terrible) ruby code. I would welcome PRs or issues which improve the code style and introduce good practices and dev-tooling into the repo.

Please take a look at the implementation notes and the roadmap if you want to contribute.
