## What it is
Bass is a Fish shell plugin that lets users run Bash utilities that modify the shell environment (like nvm or virtualenv) directly in Fish. It works by capturing environment variable changes made in a nested Bash process and replaying them in the Fish session.

## Use cases
- use nvm in fish shell
- source bash setup scripts from fish
- run bash utilities that export environment variables in fish
- activate python virtualenv written for bash while using fish
- port bash environment changes to fish without rewriting scripts

## When to choose
- you use fish shell but need bash-only tools like nvm that must be sourced
- you want to reuse bash environment setup scripts without porting them to fish syntax

## When to avoid
- you only need to run standalone bash scripts, which fish already supports via shebangs
- a native fish alternative like virtualfish already exists for your tool
- a simple `exec bash -c 'source ...; exec fish'` workflow is sufficient
