Godepmon

Godepmon is a real-time monitoring tool designed to enhance the Go development workflow by automatically observing changes in Go packages and their dependencies. Upon detecting any modifications, it executes a predefined command, offering immediate feedback and streamlining the development process for Go developers.

Features

• Watches over your Go package and its dependencies for any changes, ensuring your project is always up-to-date with the latest modifications.
• Ideal for Docker development, Godepmon automates rebuilds and eliminates manual container restarts with every code change.
• Unlike simplistic file watchers, it smartly scans for dependencies, ensuring that only relevant changes trigger the execution command. This approach avoids unnecessary builds or tests when unrelated files are modified.
• Executes a specified command (e.g., go run ., go build, go test) automatically upon detecting changes.
• Provides the flexibility of optionally including external dependencies in the monitoring process.

Getting Started

Installing

go install github.com/midsbie/godepmon@latest

Usage

To start monitoring your Go package and execute a command when changes are made, simply run:

godepmon [flags] [path] [--] [command]

Positional arguments:

• path: Optional. Specifies the Go package path to monitor. Defaults to the current directory if not provided.
• command: Optional. Specifies the command to execute when changes are detected. Defaults to go run . at given path.

Flags:

• --include-external-deps: Include external dependencies in the monitoring process.
• -v, --verbose: Increase verbosity. Use multiple times for more verbose output (up to three levels; e.g. -vvv).

Examples

Monitor the current directory and execute go test upon detecting changes:

godepmon . -- go test

Monitor a specific package and include external dependencies:

godepmon --include-external-deps ./path/to/package -- go build -v
