Makego - Template

[xmonader]

Description: Create a simple build automation tool similar to Make, but with a simpler featureset. The tool should be able to execute targets with dependencies and commands, focusing on the core functionality of a build system.

Requirements:

1. Configuration File:

   • Parse a custom configuration file Makefile
   • Support defining targets, their dependencies, and associated commands

2. Target Definition:

   • Allow users to define targets with a name
   • Support specifying dependencies for each target
   • Enable associating one or more shell commands with each target

3. Dependency Resolution:

   • Implement a dependency graph to determine the order of execution
   • Detect and report circular dependencies

4. Command Execution:

   • Execute shell commands associated with each target
   • Support running multiple commands for a single target

5. CLI Interface:

   • Accept target names as command-line arguments
   • If no target is specified, run the default target (if defined)
   • Implement a '-f' flag to specify a custom Makefile

6. Concurrency:

   • Execute independent targets concurrently using goroutines
   • Implement proper synchronization for dependent targets

7. Error Handling:

   • Provide clear error messages for configuration issues
   • Handle and report errors in command execution

8. Testing:

   • Write unit tests for core functionalities (parsing, dependency resolution)
   • Implement integration tests with sample Makefile

9. Documentation:

   • Provide clear documentation on the Makefile format
   • Include usage instructions and examples in the README

Optional Enhancements:

• Implement a dry-run mode to show what would be executed
• Add support for environment variable expansion in commands
• Implement simple variable substitution in the Makefile
