Recommendations:
  โšก Consider parallelizing 'lint' and 'test'
  ๐Ÿ’พ 'build' task has 90% cache hit rate - well optimized!

๐Ÿ› ๏ธ Developer Productivity Features

Rich Task Descriptions

Topia.task("deploy")
  .describe("Deploy application to production with health checks")
  .depends_on("build")
  .command("./scripts/deploy.sh")

Professional Error Handling

ERROR: Task 'missing-dependency' not found
Did you mean: 'build', 'test', or 'clean'?

Use 'topia --list' to see all available tasks.

Configuration Validation with Context

ERROR: Configuration syntax error in topia.yml:
  Line 15: Invalid YAML - missing closing quote

Use 'topia --validate-config' to check syntax before running.

๐Ÿ“ˆ Enterprise Features

CI/CD Integration

# Perfect for automated environments
topia --validate-config --quiet && topia -p -j 8 --stats lint test build

# Structured error reporting for log analysis

๐Ÿ“š Comprehensive Examples

๐Ÿ”ง Task Creation Patterns

Basic Tasks

# Command-only task
Topia.task("clean")
  .command("rm -rf build/")

# Multi-command task
Topia.task("deploy")
  .command("echo 'Starting deployment...'")
  .command("./scripts/build.sh")
  .command("./scripts/deploy.sh")
  .command("echo 'Deployment complete!'")

File Processing

# Process files through pipeline
Topia.task("process_assets")
  .src("./assets/**/*.{css,js}")
  .pipe(Minifier.new)
  .pipe(Gzipper.new)
  .dist("./public/")

# Watch and process
Topia.task("watch_assets")
  .watch("./assets/**/*", read_sources: true)
  .pipe(AssetProcessor.new)
  .dist("./public/")

Dependencies & Composition

# Linear dependencies
Topia.task("integration_test")
  .depends_on("unit_test")
  .command("./integration_tests.sh")

# Multiple dependencies
Topia.task("release")
  .depends_on(["test", "build", "lint"])
  .command("./release.sh")

# Complex workflow
Topia.task("full_ci")
  .depends_on(["setup"])
  .src("./src/**/*.cr")
  .pipe(Linter.new)
  .pipe(TestRunner.new)
  .command("crystal build --release")
  .dist("./releases/")

Dynamic Task Generation

# Generate tasks for multiple environments
["dev", "staging", "prod"].each do |env|
  Topia.task("deploy_#{env}")
    .depends_on("test")
    .command("./deploy.sh #{env}")
end

# Generate from configuration
configs = [
  {name: "lint", cmd: "crystal tool format --check"},
  {name: "docs", cmd: "crystal docs"},
  {name: "audit", cmd: "./security_audit.sh"}
]

configs.each do |config|
  Topia.task(config[:name])
    .command(config[:cmd])
end

๐ŸŽฏ Task Execution Methods

Direct Execution

# Run single task
Topia.run("build")

# Run multiple tasks sequentially
Topia.run(["clean", "build", "test"])

# Run with parameters

Parallel Execution

# Run independent tasks in parallel
Topia.run_parallel(["lint", "test", "docs"])

# Dependency-aware parallel execution
Topia.run_parallel(["integration_test", "build"])
# Automatically resolves: setup โ†’ test โ†’ integration_test
