# Nushell 0.108.0 Update - Complete Guide

## Quick Start (Recommended)

**Note**: If your system `nu` is broken, this workflow uses the built `./nushell/target/release/nu` binary automatically.

Run the complete update in simple steps:

```bash
# Step 1: Download Nushell source
./scripts/download_nushell.nu 0.108.0

# Step 2: Build Nushell with all features
cd nushell
cargo build --release --workspace --features "mcp,plugin,sqlite,trash-support,system-clipboard,rustls-tls"
cd ..

# Step 3: Update plugin versions
./scripts/update_all_plugins.nu 0.108.0

# Step 4: Build all plugins
just build

# Step 5: Create distributions
./scripts/create_full_distribution.nu

# Step 6: Validate everything
./scripts/update_all_plugins.nu check
just validate-code

# Step 7: Commit changes
git add -A
git commit -m "chore: update to Nushell 0.108.0"
```

## ⚠️ CRITICAL: System Nu Binary Issue (RESOLVED)

**Problem**: If your system `nu` binary (in PATH) gets killed with signal 9, the automation scripts will fail.

**Root Cause**: The system nu binary at `/Users/jesusperezlorenzo/.local/bin/nu` may be corrupted or have compatibility issues.

**Solution**: The automation scripts have been updated to use the newly built `./nushell/target/release/nu` binary instead of the system one.

**Fix Your System Nu** (recommended after update):
```bash
# Backup current system nu
mv ~/.local/bin/nu ~/.local/bin/nu.broken

# Copy working 0.108.0 binary
cp ./nushell/target/release/nu ~/.local/bin/nu

# Verify it works
nu --version  # Should show 0.108.0 without being killed
```

**Verification**:
```bash
# Test if your system nu is broken
nu --version
# If this gets "Killed: 9", your system nu is broken

# Test the built nu (should always work)
./nushell/target/release/nu --version
# Should show 0.108.0 successfully
```
