+# nvm Copilot Instructions
+
+This document provides guidance for GitHub Copilot when working with the Node Version Manager (nvm) codebase.
+
+## Overview
+
+nvm is a version manager for Node.js, implemented as a POSIX-compliant function that works across multiple shells (sh, dash, bash, ksh, zsh). The codebase is primarily written in shell script and emphasizes portability and compatibility.
+
+### Core Architecture
+
+- **Main script**: `nvm.sh` - Contains all core functionality and the main `nvm()` function
+- **Installation script**: `install.sh` - Handles downloading and installing nvm itself
+- **Execution wrapper**: `nvm-exec` - Allows running commands with specific Node.js versions
+- **Bash completion**: `bash_completion` - Provides tab completion for bash users
+- **Tests**: Comprehensive test suite in `test/` directory using the [urchin](https://www.npmjs.com/package/urchin) test framework
+
+## Key Files and Their Purposes
+
+### `nvm.sh`
+The core functionality file containing:
+- Main `nvm()` function (starts around line 3000)
+- All internal helper functions (prefixed with `nvm_`)
+- Command implementations for install, use, ls, etc.
+- Shell compatibility logic
+- POSIX compliance utilities
+
+### `install.sh`
+Handles nvm installation via curl/wget/git:
+- Downloads nvm from GitHub
+- Sets up directory structure
+- Configures shell integration
+- Supports both git clone and script download methods
+
+### `nvm-exec`
+Simple wrapper script that:
+- Sources nvm.sh with `--no-use` flag
+- Switches to specified Node version via `NODE_VERSION` env var or `.nvmrc`
+- Executes the provided command with that Node version
+
+## Top-Level nvm Commands and Internal Functions
+
+### Core Commands
+
+#### `nvm install [version]`
+- **Internal functions**: `nvm_install_binary()`, `nvm_install_source()`, `nvm_download_artifact()`
+- Downloads and installs specified Node.js version
+- Automatically `nvm use`s that version after installation
+- Supports LTS versions, version ranges, and built-in aliases (like `node`, `stable`) and user-defined aliases
+- Can install from binary or compile from source
+- When compiling from source, accepts additional arguments that are passed to the compilation task
+
+#### `nvm use [version]`
+- **Internal functions**: `nvm_resolve_alias()`, `nvm_version_path()`, `nvm_change_path()`

+
+### Running Tests
+
+#### Install Dependencies
+```bash
+npm install  # Installs urchin, semver, and replace tools
+```
+
+#### Run All Tests
+```bash
+npm test               # Runs tests in current shell (sh, bash, dash, zsh, ksh)
+make test              # Runs tests in all supported shells (sh, bash, dash, zsh, ksh)
+make test-sh           # Runs tests only in sh
+make test-bash         # Runs tests only in bash
+make test-dash         # Runs tests only in dash
+make test-zsh          # Runs tests only in zsh
+make test-ksh          # Runs tests only in ksh
+```
+
+#### Run Specific Test Suites
+```bash
+make TEST_SUITE=fast test        # Only fast tests
+make TEST_SUITE=slow test        # Only slow tests
+make SHELLS=bash test            # Only bash shell
+```
+
+#### Individual Test Execution
+```bash
+./test/fast/Unit\ tests/nvm_get_arch     # Run single test (WARNING: This will exit/terminate your current shell session)
+./node_modules/.bin/urchin test/fast/                        # Run fast test suite
+./node_modules/.bin/urchin 'test/fast/Unit tests/nvm_get_arch'  # Run single test safely without shell termination
+./node_modules/.bin/urchin test/slow/                        # Run slow test suite
+./node_modules/.bin/urchin test/sourcing/                    # Run sourcing test suite
+```
+
+### Test Writing Guidelines
+- Tests should work across all supported shells (sh, bash, dash, zsh, ksh)
+- Define and use a `die()` function for test failures
+- Clean up after tests in cleanup functions
+- Mock external dependencies when needed
+- Place mocks in `test/mocks/` directory
+- Mock files should only be updated by the existing `update_test_mocks.sh` script, and any new mocks must be added to this script
+
+## Shell Environment Setup
+
+### Supported Shells
+- **bash** - Full feature support
+- **zsh** - Full feature support
+- **dash** - Basic POSIX support
+- **sh** - Basic POSIX support
+- **ksh** - Limited support (experimental)
+
+### Installing Shell Environments
+
+#### Ubuntu/Debian
+```bash
+sudo apt-get update
+sudo apt-get install bash zsh dash ksh
+# sh is typically provided by dash or bash and is available by default
+```
+
+#### macOS
+```bash
+# bash and zsh are available by default, bash is not the default shell for new user accounts
+# Install other shells via Homebrew
+brew install dash ksh
+# For actual POSIX sh (not bash), install mksh which provides a true POSIX sh
+brew install mksh
+```
+
+#### Manual Shell Testing
+```bash
+# Test in specific shell
+bash -c "source nvm.sh && nvm --version"
+zsh -c "source nvm.sh && nvm --version"
+dash -c ". nvm.sh && nvm --version"
+sh -c ". nvm.sh && nvm --version"          # On macOS: mksh -c ". nvm.sh && nvm --version"
+ksh -c ". nvm.sh && nvm --version"
+```
+
+### Shell-Specific Considerations
+- **zsh**: Requires basically any non-default zsh option to be temporarily unset to restore POSIX compliance
+- **dash**: Limited feature set, avoid bash-specific syntax
+- **ksh**: Some features may not work, primarily for compatibility testing
+
+## CI Environment Details
+
+### GitHub Actions Workflows
+
+#### `.github/workflows/tests.yml`
+- Runs test suite across multiple shells and test suites
+- Uses `script` command for proper TTY simulation
+- Matrix strategy covers shell × test suite combinations
+- Excludes install_script tests from non-bash shells
+
+#### `.github/workflows/shellcheck.yml`
+- Lints all shell scripts using shellcheck
+- Tests against multiple shell targets (bash, sh, dash, ksh)
+  - Note: zsh is not included due to [shellcheck limitations](https://github.com/koalaman/shellcheck/issues/809)
+- Uses Homebrew to install latest shellcheck version
+
+#### `.github/workflows/lint.yml`
+- Runs additional linting and formatting checks
+- Validates documentation and code style
+
+### Travis CI (Legacy)
+- Configured in `.travis.yml`
+- Tests on multiple Ubuntu versions
+- Installs shell environments via apt packages
+
+### CI Test Execution
+```bash
+# Simulate CI environment locally
+unset TRAVIS_BUILD_DIR  # Disable Travis-specific logic
+unset GITHUB_ACTIONS    # Disable GitHub Actions logic
+make test
+```
+
+## Setting Up shellcheck Locally
+
+### Installation
+
+#### macOS (Homebrew)
+```bash
+brew install shellcheck
+```
+
+#### Ubuntu/Debian
+```bash
+sudo apt-get install shellcheck
+```
+
+#### From Source
+```bash
+# Download from https://github.com/koalaman/shellcheck/releases
+wget https://github.com/koalaman/shellcheck/releases/download/latest/shellcheck-latest.linux.x86_64.tar.xz
+tar -xf shellcheck-latest.linux.x86_64.tar.xz
+sudo cp shellcheck-latest/shellcheck /usr/local/bin/
+```
+
+### Usage
+
+#### Lint Main Files
+```bash
+shellcheck -s bash nvm.sh
+shellcheck -s bash install.sh
+shellcheck -s bash nvm-exec
+shellcheck -s bash bash_completion
+```
+
+#### Lint Across Shell Types
+```bash
+shellcheck -s sh nvm.sh      # POSIX sh
+shellcheck -s bash nvm.sh    # Bash extensions
+shellcheck -s dash nvm.sh    # Dash compatibility
+shellcheck -s ksh nvm.sh     # Ksh compatibility
+```
+
+#### Common shellcheck Directives in nvm
+- `# shellcheck disable=SC2039` - Allow bash extensions in POSIX mode
+- `# shellcheck disable=SC2016` - Allow literal `$` in single quotes
+- `# shellcheck disable=SC2001` - Allow sed usage instead of parameter expansion
+- `# shellcheck disable=SC3043` - Allow `local` keyword (bash extension)
+
+### Fixing shellcheck Issues
+1. **Quoting**: Always quote variables: `"${VAR}"` instead of `$VAR`
+2. **POSIX compliance**: Avoid bash-specific features in portable sections
+3. **Array usage**: Use `set --` for positional parameters instead of arrays, which are not supported in POSIX
+4. **Local variables**: Declared with `local FOO` and then initialized on the next line (the latter is for ksh support)
+
+## Development Best Practices
+
+### Code Style
+- Use 2-space indentation
+- Follow POSIX shell guidelines for portability
+- Prefix internal functions with `nvm_`
+- Use `nvm_echo` instead of `echo` for output
+- Use `nvm_err` for error messages
+
+### Compatibility
+- Test changes across all supported shells
+- Avoid bash-specific features in core functionality
+- Use `nvm_is_zsh` to check when zsh-specific behavior is needed
+- Mock external dependencies in tests
+
+### Performance
+- Cache expensive operations (like remote version lists)
+- Use local variables to avoid scope pollution
+- Minimize subprocess calls where possible
+- Implement lazy loading for optional features
+
+### Debugging
+- Use `nvm debug` command for environment information
+- Enable verbose output with `set -x` during development
+- Test with `NVM_DEBUG=1` environment variable
+- Check `$NVM_DIR/.cache` for cached data issues
+
+## Common Gotchas
+
+1. **PATH modification**: nvm modifies PATH extensively; be careful with restoration
+2. **Shell sourcing**: nvm must be sourced, not executed as a script
+3. **Version resolution**: Aliases, partial versions, and special keywords interact complexly
+4. **Platform differences**: Handle differences between Linux, macOS, and other Unix systems
+5. **Network dependencies**: Many operations require internet access for version lists
+6. **Concurrent access**: Multiple shells can conflict when installing versions simultaneously
+
+## Windows Support
+
+nvm works on Windows via several compatibility layers:
+
+### WSL2 (Windows Subsystem for Linux)
+- Full nvm functionality available
+- **Important**: Ensure you're using WSL2, not WSL1 - see [Microsoft's WSL2 installation guide](https://docs.microsoft.com/en-us/windows/wsl/install) for up-to-date instructions
+- Install Ubuntu or other Linux distribution from Microsoft Store
+- Follow Linux installation instructions within WSL2
+
+### Cygwin
+- POSIX-compatible environment for Windows
+- Download Cygwin from [cygwin.com](https://www.cygwin.com/install.html) and run the installer
+- During installation, include these packages: bash, curl, git, tar, and wget
+- May require additional PATH configuration
+
+### Git Bash (MSYS2)
+- Comes with Git for Windows
+- Limited functionality compared to full Linux environment
+- Some features may not work due to path translation issues, including:
+  - Binary extraction paths may be incorrectly translated
+  - Symlink creation may fail
+  - Some shell-specific features may behave differently
+  - File permissions handling differs from Unix systems
+
+### Setup Instructions for Windows
+
+#### WSL2 (recommended)
+1. Install WSL2 using the official Microsoft guide: https://docs.microsoft.com/en-us/windows/wsl/install
+2. Install Ubuntu or preferred Linux distribution from Microsoft Store
+3. Follow standard Linux installation within WSL2
+
+#### Git Bash
+1. Install Git for Windows (includes Git Bash) from https://git-scm.com/download/win
+2. Open Git Bash terminal
+3. Run nvm installation script
+
+#### Cygwin
+1. Download and install Cygwin from https://www.cygwin.com/install.html
+2. Include bash, curl, git, tar, and wget packages during installation
+3. Run nvm installation in Cygwin terminal
+
+This guide should help GitHub Copilot understand the nvm codebase structure, testing procedures, and development environment setup requirements.

+```
 
 - You can customize the install source, directory, profile, and version using the `NVM_SOURCE`, `NVM_DIR`, `PROFILE`, and `NODE_VERSION` variables.
 Eg: `curl ... | NVM_DIR="path/to/nvm"`. Ensure that the `NVM_DIR` does not contain a trailing slash.

+#### Installing in Docker
+
+When invoking bash as a non-interactive shell, like in a Docker container, none of the regular profile files are sourced. In order to use `nvm`, `node`, and `npm` like normal, you can instead specify the special `BASH_ENV` variable, which bash sources when invoked non-interactively.
+
+```Dockerfile
+# Use bash for the shell
+SHELL ["/bin/bash", "-o", "pipefail", "-c"]
+
+# Create a script file sourced by both interactive and non-interactive bash shells
+ENV BASH_ENV /home/user/.bash_env
+RUN touch "${BASH_ENV}"
+RUN echo '. "${BASH_ENV}"' >> ~/.bashrc
+
+# Download and install nvm
+RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | PROFILE="${BASH_ENV}" bash
+RUN echo node > .nvmrc
+RUN nvm install
+```
+
+##### Installing in Docker for CICD-Jobs
+
+More robust, works in CI/CD-Jobs. Can be run in interactive and non-interactive containers.
+See https://github.com/nvm-sh/nvm/issues/3531.
+
+```Dockerfile
+FROM ubuntu:latest
+ARG NODE_VERSION=20
+
+# install curl
+RUN apt update && apt install curl -y
+
+# install nvm
+RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash
+
+# set env
+ENV NVM_DIR=/root/.nvm
+
+# install node
+RUN bash -c "source $NVM_DIR/nvm.sh && nvm install $NODE_VERSION"
+
+# set ENTRYPOINT for reloading nvm-environment
+ENTRYPOINT ["bash", "-c", "source $NVM_DIR/nvm.sh && exec \"$@\"", "--"]
+
+# set cmd to bash
+CMD ["/bin/bash"]
+
+```
+
+This example defaults to installation of nodejs version 20.x.y. Optionally you can easily override the version with docker build args like:
+```
+docker build -t nvmimage --build-arg NODE_VERSION=19 .
+```
+
+After creation of the image you can start container interactively and run commands, for example:
+```
+docker run --rm -it nvmimage
+
+root@0a6b5a237c14:/# nvm -v
+0.40.3
+
+root@0a6b5a237c14:/# node -v
+v19.9.0
+
+root@0a6b5a237c14:/# npm -v
+9.6.3
+```
+
+Noninteractive example:
+```
+user@host:/tmp/test $ docker run --rm -it nvmimage node -v
+v19.9.0
+user@host:/tmp/test $ docker run --rm -it nvmimage npm -v
+9.6.3
