# asdf Version Manager Skill

asdf is a universal CLI version manager — one tool to replace nvm, pyenv, rbenv, tfenv, goenv and more. It manages per-project versions via `.tool-versions` files and switches versions automatically as you navigate directories.

---

## When to Use This Skill

Use this skill when the user is:

- **Installing or setting up asdf** on a new machine (any OS, any shell)
- **Adding plugins** for a language or tool (Node.js, Python, Go, Terraform, kubectl, Helm, etc.)
- **Installing or switching versions** of any tool managed by asdf
- **Managing `.tool-versions` files** — creating, editing, or understanding version resolution
- **Migrating from single-language version managers** like nvm, pyenv, rbenv, goenv, tfenv, or sdkman
- **Configuring shell integration** for Bash, Zsh, Fish, or Elvish
- **Debugging version resolution** — wrong version active, shims not working, `command not found` errors
- **Onboarding to a project** that uses `.tool-versions` for reproducible environments
- **Setting up CI/CD pipelines** that need deterministic tool versions via asdf
- **Configuring `.asdfrc`** for legacy file support, concurrency, or plugin repository settings

---

## Core Concepts

- **Plugin**: Adapter for a specific tool (nodejs, python, terraform, kubectl, etc.)
- **Tool**: The actual runtime/binary managed (e.g., Node.js 20.11.0)
- **.tool-versions**: Project-level file declaring exact versions; asdf resolves it by traversing up the directory tree to `$HOME`
- **Shims**: Lightweight wrappers in `~/.asdf/shims/` that intercept tool invocations and dispatch to the right version
- **Version scopes**: project (`.tool-versions` in cwd) → parent dirs → `$HOME/.tool-versions` → env var `ASDF_${TOOL}_VERSION`

---

## Installation

### Dependencies (all platforms)

```bash
# Debian/Ubuntu
sudo apt install -y git curl

# macOS
brew install git curl
```

### Install asdf binary (recommended: binary download)

```bash
# Download latest release from https://github.com/asdf-vm/asdf/releases
# Or via git clone (classic method):
git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.16.7
```

### Shell Configuration

**Fish shell** (Jean-Jacques' setup):

```fish
# Add to ~/.config/fish/config.fish
source ~/.asdf/asdf.fish

# Install completions
mkdir -p ~/.config/fish/completions
ln -s ~/.asdf/completions/asdf.fish ~/.config/fish/completions/asdf.fish
```

**Bash**:

```bash
# Add to ~/.bashrc or ~/.bash_profile
. "$HOME/.asdf/asdf.sh"
. "$HOME/.asdf/completions/asdf.bash"
```

**Zsh**:

```zsh
# Add to ~/.zshrc
. "$HOME/.asdf/asdf.sh"
```

After configuration, restart shell or `source` the config file.

## Essential Commands

### Plugin Management

```bash
asdf plugin list all              # Browse all available plugins
asdf plugin list all | grep terra # Search for specific plugins
asdf plugin add nodejs            # Add plugin by shortname (from registry)
asdf plugin add nodejs https://github.com/asdf-vm/asdf-nodejs.git  # Add by URL
asdf plugin list                  # List installed plugins
asdf plugin update nodejs         # Update a plugin
asdf plugin update --all          # Update all plugins
asdf plugin remove nodejs         # Remove plugin + all its installs
```

### Version Management

```bash
asdf list all nodejs              # List all installable versions
asdf list all nodejs 20           # List versions matching prefix
asdf install nodejs latest        # Install latest version
asdf install nodejs 20.11.0       # Install specific version
asdf install                      # Install all versions in .tool-versions
asdf list nodejs                  # List installed versions
asdf uninstall nodejs 18.0.0      # Remove a version
```

### Setting Versions

```bash
asdf set nodejs 20.11.0           # Set version in ./.tool-versions (project)
asdf set -u nodejs 20.11.0        # Set version in ~/.tool-versions (global/user default)
asdf set -p nodejs 20.11.0        # Set in nearest parent .tool-versions
asdf set nodejs latest            # Resolve and write latest version
asdf current                      # Show active version for all tools in cwd
asdf current nodejs               # Show active version for one tool
asdf where nodejs                 # Show install path for active version
asdf which node                   # Show shim path for a command
```

> **Note**: `asdf set` replaced the older `asdf local` / `asdf global` commands in asdf v0.15+. Both still work but `asdf set` is the modern API.

### Environment Variable Override

```bash
# Temporarily override without editing .tool-versions
ASDF_NODEJS_VERSION=18.0.0 node --version
```

---

## .tool-versions Format

```
nodejs 20.11.0
python 3.12.2
terraform 1.7.4
kubectl 1.29.2
golang 1.22.1
```

- One tool per line, `<name> <version>`
- Multiple versions separated by spaces (fallback chain): `python 3.12.2 2.7.18`
- Special keywords: `system` (use OS-installed version), `path:~/my/custom/build`
- Commit to version control — this is the contract for the project's tool versions

---

## .asdfrc Configuration

Located at `~/.asdfrc`:

```ini
# Support .nvmrc, .ruby-version, etc. (per-plugin support required)
legacy_version_file = yes

# Keep downloaded archives (useful for slow connections)
always_keep_download = no

# Concurrency for parallel installs
concurrency = auto

# Plugin repository refresh interval in minutes
plugin_repository_last_check_duration = 60
```

## Common Plugins for DevOps/Cloud (Jean-Jacques' stack)

| Tool | Plugin add command |
|------|-------------------|
| Node.js | `asdf plugin add nodejs` |
| Python | `asdf plugin add python` |
| Go | `asdf plugin add golang` |
| Terraform | `asdf plugin add terraform` |
| kubectl | `asdf plugin add kubectl` |
| Helm | `asdf plugin add helm` |
| gcloud CLI | `asdf plugin add gcloud` |
| Skaffold | `asdf plugin add skaffold` |
| Java | `asdf plugin add java` |
| Ruby | `asdf plugin add ruby` |
| Erlang | `asdf plugin add erlang` |
| Elixir | `asdf plugin add elixir` |

Many plugins may require system dependencies — always check the plugin's README before installing.

---

## Migration from Other Version Managers

Enable legacy file support in `~/.asdfrc`:

```ini
legacy_version_file = yes
```

| Old file | Tool |
|----------|------|
| `.nvmrc` | nodejs (via asdf-nodejs) |
| `.node-version` | nodejs |
| `.ruby-version` | ruby (via asdf-ruby) |
| `.python-version` | python (via asdf-python) |

---

## Troubleshooting

### Shims not working / command not found

```bash
asdf reshim nodejs          # Regenerate shims for a plugin
asdf reshim                 # Regenerate all shims
echo $PATH                  # Verify ~/.asdf/shims is early in PATH
type -a node                # Fish: check which binary is resolved
```

### Version not being picked up

```bash
asdf current                # See what version is resolved and from where
# Look for "No version set" warnings
# Check .tool-versions exists in project dir or a parent
```

### Plugin install failures

- Check plugin README for system dependency requirements
- Ensure git is installed and accessible
- For nodejs: may need `gnupg` for keyring verification

### Data directory

Default: `~/.asdf/` — override with `export ASDF_DATA_DIR=/custom/path` in shell config.

## Typical Project Onboarding Workflow

```bash
# 1. Clone project
git clone <repo> && cd <repo>

# 2. Add plugins for each tool in .tool-versions (if not already added)
asdf plugin add nodejs
asdf plugin add python

# 3. Install all versions specified in .tool-versions
asdf install

# 4. Verify
asdf current
```
