Exported Fish Environment: ros2-assignments

This directory contains a self-contained Fish shell environment that can be used without requiring the original Fish configuration.

Files Structure

.fish/
├── activate.fish    # Main environment configuration
└── README.md        # This file

Usage

Automatic Activation (Recommended)

The environment will automatically activate when you cd into this directory if your Fish shell is configured with the auto-activation feature that checks for .fish/activate.fish.

Manual Activation

To manually activate the environment, run from the project root:

source ./.fish/activate.fish

Deactivation

To deactivate the environment, run:

env deactivate

Or simply cd to a different directory if using auto-activation.

What This Environment Provides

Custom prompt showing the environment name
Environment-specific aliases and functions
Custom environment variables
Automatic cleanup when deactivated

Requirements

Fish shell
If this is a ROS2 environment: bass plugin (fisher install edc/bass)

This environment is completely self-contained. You can:

Copy this directory to another machine
Share it with other Fish shell users
Version control it with your project (add .fish/ to your repo)

The environment will work on any system with Fish shell, regardless of whether they have the original environment management system installed.

Auto-activation Setup

To enable auto-activation for .fish/activate.fish, add this to your Fish config.fish:

function check_and_source_activate
  if test -f (pwd)/.fish/activate.fish
    source (pwd)/.fish/activate.fish
  elif test -f (pwd)/activate.fish
    source (pwd)/activate.fish
  end
end

function cd
  builtin cd $argv && check_and_source_activate
end
