FORAY: Sep 09, 2023 - Golang
Install Go on Hetzner Arch machine and create script to create HTML that is accessible on subdomain

CONTINUE: start working through book, data types

  • set up go.tkserv.eu subdomain
  • now install Go
  • create Go script that creates a text file
    • asked ChatGPT
    • creating repository so I can copy it in, difficult in terminal to copy
      • created repository
      • initialized local repository, git init -b dev
      • pushing existing repository
      • made file, git add ., git commit -m "initial commit"
      • git remote add origin git@github.com:edwardtanguay/et034-golang-site.git
      • git push -u origin dev
      • it's in the repository
    • gensite.go
      • package main
         
        import (
            "fmt"
            "os"
        )
         
        func main() {
            // Define the file name
            fileName := "example.txt"
         
            // Create or open the file for writing, create it if it doesn't exist, truncate if it does
            file, err := os.Create(fileName)
            if err != nil {
                fmt.Println("Error creating file:", err)
                return
            }
            defer file.Close()
         
            // Write content to the file
            content := "Hello, this is some text written to the file!"
            _, err = file.WriteString(content)
            if err != nil {
                fmt.Println("Error writing to file:", err)
                return
            }
         
            fmt.Println("File created and content written successfully.")
        }
    • git pull worked
    • when run, it locks up
    • but then finishes after 20 seconds
    • then worked:
    • ok, then worked:
  • now create an HTML file
    • backticks work just like in JavaScript
    • the script has been created in current directory
  • now create the file that is served on the site
    • gensite.go - works well
      • package main
         
        import (
            "fmt"
            "os"
