✅ Features Added:
• Complete script sourcing implementation via source/. commands
• Deferred execution system to avoid circular dependencies
• Proper file existence and permissions checking
• Line-by-line script execution with full shell features
• Comment skipping and empty line handling
• History integration for sourced commands
• Exit handling to stop script execution properly
🔧 Technical Implementation:
• Added source_file and should_source fields to shell_state_t
• Created process_source_file() subroutine in main shell loop
• Enhanced builtin_source() with queuing mechanism
• Fixed Makefile dependencies to resolve circular issues
• Maintained compatibility with both 'source' and '.' commands
🧪 Testing:
• Verified script execution with variables, echo, pwd commands
• Confirmed both 'source' and '.' command aliases work
• Tested proper variable persistence after script execution
🎯 Phase 6 Progress: 1/5 features complete
Next: Command substitution implementation
