direnv - Snap

direnv is an environment switcher for the shell. It knows how to hook into bash, zsh, tcsh, fish shell and elvish to load or unload environment variables depending on the current directory. This allows project-specific environment variables without cluttering the ~/.profile file.

This repository contains the code for the direnv snap package.

NOTE: It works on Ubuntu, Fedora, Debian, and other major Linux distributions.

Prerequisites

Prerequisites include a linux installation and the snapd service. In order to install snapd please follow the Install snapd guide.

Installation

In order to install the direnv snap use the 'snap' cli i.e :

sudo snap instal --classic

Setup

For direnv to work properly it needs to be hooked into the shell. Each shell has its own extension mechanism:

BASH

Add the following line at the end of the ~/.bashrc file:

eval "$(direnv hook bash)"

Make sure it appears even after rvm, git-prompt and other shell extensions that manipulate the prompt.

ZSH

Add the following line at the end of the ~/.zshrc file:

eval "$(direnv hook zsh)"

FISH

Add the following line at the end of the ~/.config/fish/config.fish file:

eval (direnv hook fish)

TCSH

Add the following line at the end of the ~/.cshrc file:

eval `direnv hook tcsh

Elvish (0.12+)

Run:

$> direnv hook elvish > ~/.elvish/lib/direnv.elv

and add the following line to your ~/.elvish/rc.elv file:

use direnv
l direnv

Build

Checkout the source code and from inside the snap directory execute the following command :
