Galus - Live Reloading for Go Applications

English | Bahasa Indonesia

Galus is a live reloading tool for Go applications, similar to Air or CompileDaemon. It monitors file changes in your project, automatically recompiles, and restarts the application.

Features

• Live Reloading: Automatically detects changes in specified file types (e.g., .go) and recompiles and restarts the application.

• Configurable via .galus.toml: Customize watched directories, file extensions, build commands, and runtime arguments using a TOML configuration file.

• Colorful CLI Output: Provides clear, color-coded output for better user experience (e.g., green for success, red for errors).

• Rich CLI Commands: Supports init to create a default configuration file, version to display the app version, and help for command usage details.

• Graceful Shutdown: Uses SIGTERM to safely stop running processes, with a fallback to force termination if needed.

• Configuration Validation: Ensures build_cmd and command_args are valid before starting the live reload process.

• Cross-Platform: Works on any platform supported by Go, with easy installation via go get.

Installation

1. Install galus using go get:

   go get github.com/aliftech/galus

2. Install the binary to make galus available globally:

   go install github.com/aliftech/galus

3. Ensure $GOPATH/bin is in your $PATH:

   export PATH=$PATH:$(go env GOPATH)/bin

Usage

1. Initialize a configuration file: In your project directory, run:

   galus init

   This creates a .galus.toml configuration file with default setting.

2. Start live reloading: In your project directory, run:

   galus

   Galus will monitor file changes (e.g., .go files), recompile, and restart your application.

Configuration

The .galus.toml file allows you to customize Galus behavior. Example configuration:

root_dir = "."
tmp_dir = "tmp"
include_ext = ["go"]
exclude_dir = [".git", "vendor", "tmp"]
build_cmd = "go build -o ./tmp/main ."
binary_name = "tmp/main"
command_args = ["tmp/main"]

• root_dir: Directory to monitor for changes.
• tmp_dir: Temporary directory for compiled binaries.
• include_ext: File extensions to monitor (e.g., ["go", "html"]).
• exclude_dir: Directories to ignore.
• build_cmd: Command to compile the application.
• binary_name: Name of the compiled binary.
• command_args: Arguments to run the binary.
