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: “Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system.”

A block of code is set as follows:

employee_name = get_user_input() 
sql = "SELECT salary FROM employee_records WHERE employee_name = $employee_name" ENTERcall_database(sql) 

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

deploy-to-staging: 
stage: staging 
script: ./deploy-staging.sh 
tags: 
- windows 
- staging 

Any command-line input or output is written as follows:

$ git --version 
git version 2.25.1

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: “Select System info from the Administration panel.”
