esvu

esvu is your one-stop shop for all implementations of ECMAScript.

Installation

``
$ npm i -g esvu
`

esvu will attempt to respect XDG_DATA_HOME, and will fall back to the
home directory. You will need to add esvu's bin to your PATH, for
example $XDG_DATA_HOME/.esvu/bin or /home/snek/.esvu/bin.

You may override the path entirely by setting the ESVU_PATH environment
variable.

Usage

The first time you run esvu, it will ask you which engines you wish to
install. After the first run, running esvu will update the engines you
selected.

- $ esvu
Update all installed engines, or select engines to install
- $ esvu install
Install the engine
- $ esvu uninstall
Uninstall
- $ esvu update
Update . Like install but the engine must have been previously
installed.

If you're using [eshost-cli][], you can run eshost --configure-esvu after
installing engines to make eshost automatically find the installed engines.
