cuttlefish

Switch environment according to current working directory. Heavily inspired by the amazing direnv but not limited to environment variables and only targeting fish shell.

Features

Configure any combination of the following in a simple YAML file:

• ssh identities
• paths (to append to $fish_user_paths, which then becomes a universal variable)
• global (= universal) variables
• git user email address

Whenever you visit a directory containing a .cuttlefish.yaml file, its configuration is applied to your environment.

Note: Only subdirectories of the user's home directory are scanned.

Install

Note: The script installs itself in your ~/.config/fish/config.fish: before doing so, though, it will copy the original file to ~/.config/fish/config.fish_bck so that it can be restored if needed (see install target in Makefile for more details).

Option 1: Install released binaries

Grab the binaries from the releases page, uncompress them and run

cd cuttlefish-darwin64
make install

Option 2: Build from sources

The installation requires Go 1.13+.

git clone https://github.com/fedragon/cuttlefish
cd cuttlefish
make

Usage

Create a .cuttlefish.yaml in every directory where you want to load a different environment. The file should look like this:

git_config:
  email: foo@bar.com # only this field is currently supported
ssh_identities:
  - ~/.ssh/id_rsa1
  - ~/.ssh/id_rsa2
# - ...
user_paths:
  - ~/Documents
  - ~/Desktop
# - ...
global_variables:
  FOO: bar
# x: y
# ... : ...

Any combination of the above fields is possible and they're all optional. A complete example is available in examples/cuttlefish.yaml.
