Conventions used
There are a number of text conventions used throughout this book.
Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The x variable is declared with a value of 100 using the := symbol."
A block of code is set as follows:
const ( app_name = 'V on Wheels' max_connections = 1000 decimal_places = 2 pi = 3.14 )
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
import json
fn main() {
m := Note{
id: 2
message: 'Get groceries'
status: false
}
j := json.encode(m)
println(j)
}
Any command-line input or output is written as follows:
sudo apt -y update sudo apt install -y build-essential
Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "Now select the Body tab, and check the raw radio button."
