## 🚀 Quick Start

### For End Users (Zero Prerequisites)

```bash
# One-liner installation
curl -sSf https://your-url/install.sh | sh

# Or download and install manually
wget https://releases/nushell-full-linux-x86_64.tar.gz
tar -xzf nushell-full-*.tar.gz && cd nushell-full-* && ./install.sh
```

### For Developers

#### Prerequisites
```bash
# Install required tools
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh  # Rust
cargo install just                                              # Just (optional but recommended)
# Note: Nushell will be auto-installed if missing
```

#### Development Workflow
```bash
# Clone the repository
git clone <repository-url>
cd nushell-plugins

# Validate nushell version consistency (recommended first step)
just validate-nushell

# Plugin development
just status              # Show plugin status
just status-mark-locals-ok  # Mark local plugins as OK (recommended)
just upstream-check      # Check for upstream updates
just build              # Build all plugins
just dev-flow           # Complete development workflow

# Distribution creation
just build-nushell       # Build nushell + system plugins (uses --workspace flag)
just build-full          # Build nushell + system plugins + custom plugins
just collect             # Collect nushell + all plugins for distribution
just pack-full           # Create distribution package
just release-full-cross  # Complete cross-platform release
```

### ⚠️ Critical: Version Consistency

**This system requires version consistency between your installed nushell and the submodule version.** All operations automatically check version consistency and will fail if versions don't match.

- **Auto-fix**: `just fix-nushell` or `./scripts/run.sh --fix --check-only`
- **Manual check**: `just validate-nushell`

## 🎯 Full Distribution System

### What is it?

The Full Distribution System transforms this repository from a **development-focused plugin collection** into a **complete Nushell distribution platform**. Instead of requiring users to install Rust, clone repositories, and build plugins, they can now install a complete Nushell environment with a single command.

### End User Experience

**Before**: Complex development setup required
```bash
# Users needed to:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh  # Install Rust
git clone repository && cd nushell-plugins                      # Clone repo
just validate-nushell && just build                            # Build everything
# ... multiple complex steps
```

**After**: Zero-prerequisite installation
```bash
# Users now only need:
curl -sSf https://your-url/install.sh | sh  # Done!
```

```

## 🎛️ Upstream Tracking System

### How It Works

The upstream tracking system automatically:

1. **Fetches** latest changes from upstream repositories
2. **Analyzes** differences between local and upstream code
3. **Auto-approves** changes that only affect nu_* dependencies
4. **Flags** other changes for manual review
5. **Preserves** local modifications during merges
6. **Excludes** specified plugins from tracking operations

### Configuration

#### Plugin Registry (`etc/plugin_registry.toml`)

```toml
[plugins.nu_plugin_example]
upstream_url = "https://github.com/user/nu_plugin_example"
upstream_branch = "main"
auto_ok_on_nu_deps_only = true  # Auto-approve nu_* dependency changes
status = "unknown"              # Current status
```

#### Exclusion Configuration (`etc/upstream_exclude.toml`)

Control which plugins are excluded from upstream operations:

```toml
[exclude]
# Plugins to exclude from ALL upstream operations
plugins = [
    "nu_plugin_manual_only",
    "nu_plugin_deprecated"
]

[exclude.check]
# Exclude from checking only (can still be manually merged)
plugins = [
    "nu_plugin_no_auto_check"
]

[exclude.merge]
# Exclude from automatic merging (but can still be checked)
plugins = [
    "nu_plugin_complex_merge"
]

[exclude.patterns]
# Exclude plugins matching patterns
plugins = [
    "nu_plugin_test_*",
    "nu_plugin_experimental_*"
]
```

### Commands

```bash
# Check all upstream sources
just upstream-check

# Check specific plugin
just upstream-check-plugin nu_plugin_clipboard

# Preview changes before merging
just upstream-preview nu_plugin_clipboard

# Safely merge upstream changes
just upstream-merge nu_plugin_clipboard

# Merge all pending changes
just upstream-merge-all

# Manage exclusions
just exclude nu_plugin_test add      # Add to exclusion list
just exclude nu_plugin_test remove   # Remove from exclusion list
just exclude-list                    # Show all excluded plugins
```

### Status System

| Status | Description | Action Required |
|--------|-------------|-----------------|
| ✅ `ok` | Synchronized with upstream | None |
| ⚠️ `pending` | Changes detected, needs review | Manual review |
| ❌ `error` | Error during sync | Investigation |
| 🔥 `conflict` | Merge conflicts | Manual resolution |
| ❓ `unknown` | Not yet checked | Run upstream check |
| 🏠 `local_only` | No upstream repository | None |

### Status Management

#### Manual Status Updates

You can manually update plugin status using justfile recipes or scripts:

```bash
# Update specific plugin status
just status-update PLUGIN STATUS
just status-update nu_plugin_image ok

# Mark all local development plugins as OK (recommended)
just status-mark-locals-ok

# Using scripts directly
./scripts/run.sh plugin_status.nu update nu_plugin_hashes ok
```

#### Common Status Management Tasks

```bash
# Check current status
just status                    # Full dashboard
just status-summary           # Quick summary only
just status-attention         # Only plugins needing attention

# Mark local plugins as reviewed/OK
just status-mark-locals-ok     # Marks nu_plugin_image, nu_plugin_hashes, nu_plugin_desktop_notifications as OK

# Individual updates
just status-update nu_plugin_image ok
just status-update nu_plugin_highlight pending
```

#### When to Update Status

- **Local plugins** (`nu_plugin_image`, `nu_plugin_hashes`, `nu_plugin_desktop_notifications`): Mark as `ok` after reviewing local changes
- **Upstream plugins**: Status is automatically managed by `just upstream-check`
- **Manual override**: Use `status-update` when you need to override automatic status detection

## 🛠️ Scripts and Tools

### Consolidated Script System

The repository now uses a **unified script system** with automatic nushell detection and **mandatory version consistency checking**.

```

### Using the Universal Script Runner

**All nushell scripts should be run through the universal wrapper for automatic version checking:**

```bash
# Universal wrapper with automatic version checking
./scripts/run.sh <script_name> [args...]

# Status and information
./scripts/run.sh plugin_status.nu           # Show dashboard
./scripts/run.sh plugin_status.nu --all     # Include local plugins
./scripts/run.sh plugin_status.nu summary   # Quick summary

# Upstream tracking
./scripts/run.sh check_upstream_changes.nu                    # Check all
./scripts/run.sh check_upstream_changes.nu --plugin highlight # Check one
./scripts/run.sh safe_merge_upstream.nu highlight             # Merge one
./scripts/run.sh safe_merge_upstream.nu --all                 # Merge all pending

# Development
./scripts/run.sh build_all.nu              # Build all plugins
./scripts/run.sh update_nu_versions.nu     # Update nu dependencies

# Version management
./scripts/run.sh --check-only               # Only check version consistency
./scripts/run.sh --fix --check-only        # Auto-fix version mismatches
```

### Direct Nushell Script Usage (Advanced)

**⚠️ Warning: Direct usage skips the universal wrapper's version checking - not recommended**

```bash
# Run from repository root (version checking included in each script)
nu scripts/plugin_status.nu
nu scripts/check_upstream_changes.nu --plugin highlight
nu scripts/build_all.nu --verbose
```

### Version Consistency System

Every script automatically validates that your system nushell version matches the submodule version:

- **Automatic detection**: Missing nushell is auto-installed
- **Version validation**: System vs submodule version comparison
- **Auto-fix capability**: `--fix` flag resolves version mismatches
- **Clear error messages**: Detailed guidance when issues occur

## ❓ FAQ

### Q: Why do I get "Version mismatch detected" errors?

**A:** This system requires your installed nushell version to match the submodule version for consistency. All operations automatically check version consistency and will fail if versions don't match.

**Solutions:**
- **Auto-fix**: `just fix-nushell` or `./scripts/run.sh --fix --check-only`
- **Manual check**: `just validate-nushell`
- **Skip (not recommended)**: `./scripts/run.sh --no-version-check script.nu`

### Q: What happened to the bash wrapper scripts?

**A:** The repository has been consolidated to eliminate script duplication. The old bash wrappers in `scripts/sh/` have been removed in favor of:
- **Universal wrapper**: `./scripts/run.sh` with automatic version checking
- **Direct nu scripts**: All scripts moved from `scripts/nu/` to `scripts/`
- **Just recipes**: Updated to use the new system

### Q: How does the new script system work?

**A:** The new system provides:
1. **Universal wrapper** (`scripts/run.sh`) with automatic nushell detection and version validation
2. **Consolidated scripts** - all nu scripts in `scripts/` directory
3. **Mandatory version checking** - every operation validates version consistency
4. **Auto-installation** - missing nushell is automatically installed

### Q: How does automatic upstream tracking work?

**A:** The system fetches changes from upstream repositories and analyzes them. If only nu_* dependencies changed (like nu-plugin, nu-protocol), it automatically marks the plugin as "OK". Other changes are flagged for manual review. You can exclude specific plugins from tracking using the `etc/upstream_exclude.toml` file.

### Q: What happens to my local changes during upstream merges?

**A:** Local changes are preserved. The system:
1. Creates backup branches before any merge
2. Applies upstream changes in a temporary branch
3. Restores your local nu_* dependency versions
4. Tests compilation before applying changes
5. Rolls back on any failure

### Q: Can I disable automatic upstream tracking for a plugin?

**A:** Yes, set `auto_ok_on_nu_deps_only = false` in `etc/plugin_registry.toml` for that plugin.

### Q: How do I add a new plugin to the repository?

**A:** Use the template generator:
```bash
just make-plugin nu_plugin_myfeature
# or
nu scripts/nu/make_plugin.nu nu_plugin_myfeature
```

### Q: What if upstream tracking fails?

**A:** Check the plugin status with `just status`. Failed plugins show error details. Common issues:
- Network connectivity to upstream repository
- Authentication for private repositories
- Merge conflicts requiring manual resolution

### Q: How do I update nushell dependency versions?

**A:** Use the version updater:
```bash
just update-nu-versions       # Update all plugins
just list-nu-versions         # Show current versions
```

### Q: Can I use this with my own private plugins?

**A:** Yes! Add your private repository URLs to `etc/plugin_registry.toml`. The system supports SSH URLs for private repositories.

### Q: How do I distribute plugins to other systems?

**A:** Use the distribution pipeline:
```bash
just build                    # Build all plugins
just collect                  # Collect binaries
just pack                     # Create archive
```

The resulting archive contains all binaries and installation scripts.

### Q: What's the difference between shell scripts and nushell scripts?

**A:**
- **Nushell scripts** (`scripts/nu/`): Primary implementation with full features
- **Shell scripts** (`scripts/sh/`): Wrappers for compatibility with non-nushell environments
- Both provide the same functionality, use whichever fits your environment

### Q: How do I contribute a new plugin?

**A:**
1. Create the plugin: `just make-plugin nu_plugin_yourname`
2. Implement your functionality
3. Add upstream URL to `etc/plugin_registry.toml` if it has one
4. Test: `just build-plugin nu_plugin_yourname`
5. Submit a pull request

### Q: How do I exclude plugins from upstream tracking?

**A:** Edit `etc/upstream_exclude.toml` to exclude plugins from specific operations:
- Add to `[exclude]` section to exclude from all operations
- Add to `[exclude.check]` to skip automatic checks
- Add to `[exclude.merge]` to prevent automatic merging
- Use patterns like `nu_plugin_test_*` to exclude multiple plugins

You can also use Just commands:
```bash
just exclude nu_plugin_test add      # Add to exclusion
just exclude nu_plugin_test remove   # Remove from exclusion
just exclude-list                    # Show excluded plugins
```

### Q: Can I use this system for other Rust projects?

**A:** The upstream tracking and dependency management concepts can be adapted, but this system is specifically designed for nushell plugins with nu_* dependencies.
