002 package requires npm

✓ Passing This code compiles and runs correctly.

Code

// Test 632: Basic package requirements (npm)
// Validates that std/package:requires.npm captures npm dependencies
//
// This test demonstrates:
// 1. Self-describing modules with npm dependencies
// 2. AST collection: Compiler walks AST to find std/package:requires.npm
// 3. Void events: No branches needed for simple requirements
// 4. package.json generation with --install-packages flag

// Import package manager events from koru_std
~import std/package

// Declare npm package dependencies using implicit Source blocks
// The { } block is compiled to a Source parameter containing raw JSON
~std/package:requires.npm {
    "@koru/graphics": "^1.0.0"
}

~std/package:requires.npm {
    "@korulang/gzip": "^1.0.0"

Test Configuration

Post-validation Script:

#!/bin/bash
# Verify npm package requirements are captured in AST

# Get AST as JSON
AST_JSON=$(koruc --ast-json input.kz 2>&1 | grep -v "^DEBUG:")

# Check that the Source parameter value contains the expected npm packages
if echo "$AST_JSON" | grep -q '@koru/graphics'; then
    echo "✓ Source parameter captured @koru/graphics requirement in AST"
else
    echo "✗ Source parameter did NOT capture @koru/graphics requirement"
    echo "AST JSON (first 100 lines):"
    echo "$AST_JSON" | head -100
    exit 1
fi

if echo "$AST_JSON" | grep -q '@korulang/gzip'; then
    echo "✓ Source parameter captured @korulang/gzip requirement in AST"
else
    echo "✗ Source parameter did NOT capture @korulang/gzip requirement"
    exit 1
fi

if echo "$AST_JSON" | grep -q '@korulang/sqlite3'; then
    echo "✓ Source parameter captured @korulang/sqlite3 requirement in AST"
else
    echo "✗ Source parameter did NOT capture @korulang/sqlite3 requirement"
    exit 1
fi

echo "✓ All three npm packages present in AST"

# Note: package.json generation will be tested once --install-packages flag is implemented
# For now, we just verify that:
# 1. The void event syntax works (compilation succeeds)
# 2. Source parameters are captured in AST

echo "✅ All validations passed!"
exit 0
