copilot-swe-agent[bot] d875787ef1 fix(go): preserve ~/go across version upgrades
Previously, each `go install` upgrade would create a new versioned
`go-bin-vX.Y.Z` directory and symlink `~/go` to it, effectively
hiding all globally-installed Go tools on every upgrade.

New behavior in pkg_link():
- New install: create ~/go as a real directory (not a symlink)
- Existing versioned symlink: rename go-bin-vX.Y.Z to the stable
  unversioned path ~/.local/opt/go-bin, preserving all installed tools
- Already migrated (symlink to go-bin) or real dir: leave untouched
- Broken symlink: recreate ~/go as a real directory

Cheat Sheet

Go is designed, through and through, to make Software Engineering easy. It's fast, efficient, reliable, and something you can learn in a weekend.

If you subscribe to The Zen of Python, you'll love > Go.

You may also want to install the Go IDE tooling: go-essentials.

Hello World

  1. Make and enter your project directory

    mkdir -p ./hello/cmd/hello
    pushd ./hello/
    
  2. Initialize your go.mod to your git repository url:

    go mod init github.com/example/hello
    
  3. Create a hello.go

    cat << EOF >> ./cmd/hello/hello.go
    package main
    
    import (
      "fmt"
    )
    
    func main () {
      fmt.Println("Hello, World!")
    }
    EOF
    
  4. Format, build, and run your ./hello

    go fmt ./...
    go build -o hello ./cmd/hello/
    ./hello
    

    You should see your output:

    > Hello, World!
    

How to run a Go program as a service

On Linux:

# Install serviceman (compatible with systemd)
webi serviceman
# go into your programs 'opt' directory
pushd ./hello/

# swap 'hello' and './hello' for the name of your project and binary
serviceman add --name 'hello' -- \
    ./hello

# Restart the logging service
sudo systemctl restart systemd-journald
