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:
package main import ( "encoding/json" "fmt" "os" "time" "github.com/confluentinc/confluent-kafka-go/kafka" "movieexample.com/rating/pkg/model" )
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
if err := p.Produce(&kafka.Message{
TopicPartition: kafka.TopicPartition{Topic: &topic, Partition: kafka.PartitionAny},
Value: []byte(encodedEvent),
}, nil); err != nil {
return err
}
return nil
Any command-line input or output is written as follows:
mysql movieexample -h localhost -P 3306 --protocol=tcp -u root -p
Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Select System info from the Administration panel.”
