Go Programming Language

Guidelines for working effectively with Go projects.

Reading Dependency Source Files

To see source files from a dependency, or to answer questions about a dependency:

bash

go mod download -json MODULE

Use the returned Dir path to read the source files.

Reading Documentation

Use go doc to read documentation for packages, types, functions, etc:

bash

go doc foo.Bar       # Documentation for a specific symbol
go doc -all foo      # All documentation for a package

Running Programs

Use go run instead of go build to avoid leaving behind build artifacts:

bash

go run .             # Run the current package
go run ./cmd/foo     # Run a specific command
