fmon

fmon is a command-line tool to monitor file changes in a directory and automatically rerun a specified command when changes are detected. It's designed to improve development workflows by automating the restart of processes, such as application servers, when code is modified.

Features

• Directory Monitoring: Watches a specified directory (defaults to the current directory) for file changes.
• Automatic Command Restart: Restarts a specified command whenever a change is detected.
• Customizable Watch Directory: Use a flag to set a custom directory to monitor, accepting both relative and absolute paths.
• Colorful Console Output (WIP): Displays monitored commands, directories, and file changes in a readable neon-green format.

Installation

1. Clone the repository:

git clone https://github.com/yourusername/fmon.git
cd fmon

2. Build the application:

go build -o fmon

3. Run the binary:

./fmon

Usage

The basic syntax of the fmon command is:

fmon run "<command>" [flags]

Examples

1. Monitor Current Directory:

To monitor the current directory and rerun a command (e.g., go run main.go) whenever a file changes:

fmon run "go run main.go"

2. Monitor a Custom Directory:

To specify a different directory to monitor (relative or absolute path), use the --dir or -d flag:

fmon run "go run main.go" --dir "./path/to/dir"

Flags

• --dir, -d: Specify a directory to watch. Defaults to the current directory.

Example Output

Command: go run main.go
Watching directory: /path/to/project

File modified: /path/to/project/main.go

Development

This project uses watcher to monitor file changes and Cobra for CLI functionality. To modify or extend fmon, explore the main files and directories:

• cmd/: Contains CLI commands and flags.
• watcher/: Manages file monitoring and detects changes.
• process/: Handles running and restarting commands.
