Refactor cat and tail flag logic for better readability

2025-06-26T15:23:49+00:00

Replace the cryptic boolean expressions with clearer if-else logic that
explicitly handles the flag combinations:

Old logic (functionally correct but hard to understand):
    let show_stdout = !args.stderr || args.stdout;
    let show_stderr = !args.stdout || args.stderr;

New logic (clear and self-documenting):
    let show_stdout = if args.stdout || args.stderr {
        args.stdout
    } else {
        true // Show both when no flags are specified
    };

This change improves code readability while maintaining identical behavior:
- No flags: show both stdout and stderr
- --stdout only: show only stdout
- --stderr only: show only stderr
- Both flags: show both stdout and stderr

Add comprehensive root directory validation tests

2025-06-26T15:21:49+00:00

These tests cover edge cases including:
- Root directory specified as file instead of directory
- Non-existent root directories
- .demon directory exists as file in git root
- Permission denied scenarios
- Symlink handling (valid and broken)
- Invalid UTF-8 paths
- Deeply nested paths

Most validation is already working correctly, but these tests
document and verify the expected behavior for edge cases.

Add clippy check to pre-commit hook and fix all clippy warnings

2025-06-23T09:44:45+00:00

- Enhanced pre-commit hook to run cargo clippy with -D warnings
- Fixed uninlined_format_args warnings by using variables directly in format strings
- Removed needless borrows in .args() calls
- Fixed print_literal warnings by moving literals out of format placeholders
- Replaced seek_from_current with stream_position for better semantics
- Fixed len_zero warning by using is_empty() instead of len() > 0

All code now passes both cargo fmt and cargo clippy checks

Change default root directory to use .demon subdirectory

2025-06-22T21:15:14+00:00

- Modified find_git_root() to create and return /.demon instead of 
- Auto-creates .demon directory if it doesn't exist
- Added proper error handling for edge cases (file vs directory conflicts, permissions)
- Maintains backward compatibility with explicit --root-dir flag
- Added comprehensive test to verify new default behavior
- Fixed test argument ordering for test_list_empty

Files are now organized as:
- Before: /project/daemon.pid, /project/daemon.stdout, /project/daemon.stderr
- After: /project/.demon/daemon.pid, /project/.demon/daemon.stdout, /project/.demon/daemon.stderr

Add environment variable support for root directory configuration

2025-06-19T16:13:33+00:00

Enable setting the root directory via DEMON_ROOT_DIR environment variable by adding 'env' feature to clap and configuring the root_dir argument to read from environment.

Add configurable root directory for daemon files with git root discovery

2025-06-19T16:11:09+00:00

Implement --root-dir global option to specify where daemon files (PID, stdout, stderr) are created. When not specified, automatically searches upward for git repository root. This addresses the issue of daemon files being scattered across various working directories.

Key features:
- Global --root-dir option available on all commands
- Automatic git root discovery when --root-dir not specified
- Proper error handling for invalid directories
- Updated all file operations to use configurable root directory
- Optimized HashMap usage with PathBuf for better performance
- Fixed ID extraction to show daemon names instead of full paths
- Updated tests to work with new directory structure

Enhance tail command with follow mode control and line count options

2025-06-19T15:47:58+00:00

Add -f/--follow flag to control real-time following behavior and -n/--lines option to specify number of lines to display. By default, tail now shows the last 50 lines and exits, only following when -f is explicitly provided.

Add wait subcommand for blocking until process termination

2025-06-19T09:03:56+00:00

Implements a new 'wait' subcommand that blocks until a specified daemon process terminates, with configurable timeout and polling interval.

Features:
- Default 30-second timeout, configurable with --timeout flag
- Infinite wait with --timeout 0
- Configurable polling interval with --interval flag (default 1 second)
- Quiet operation - only shows errors on failure
- Preserves PID files (doesn't clean up)
- Exit codes: 0 for success, 1 for failure

Usage examples:
- demon wait my-process                    # Wait 30s
- demon wait my-process --timeout 0        # Wait indefinitely
- demon wait my-process --timeout 60 --interval 2  # Custom timeout/interval

Added comprehensive test suite covering:
- Non-existent processes
- Already terminated processes
- Normal process termination
- Timeout scenarios
- Infinite timeout behavior
- Custom polling intervals

Updated documentation:
- README.md with wait command reference and usage examples
- LLM guide with detailed wait command documentation
- Integration examples for development workflows
