Prettier Zap

in simple terms, it pretty prints zap logs and let you query them!

If you are using Zap Logger, you can use Prettier Zap cli for:

• making the raw JSON outputs of Zap more readable for developer
• making query base on timestamp, level, caller or a specific (key, value) pair

all non-zap logs are treated as debug logs with the caller field set to the user-code string

How To Install?

go get -u github.com/hadisinaee/prettierzap
# or
go dep ensure --add github.com/hadisinaee/prettierzap

How To Use It?

Quick Start

If your program logs into stdout, you can simply pipe it to the pz command:

go run main.go | pz

or if it's written to a file:

tail -f .log | pz

You can add a -e to all the following commands to make the logs look funny with emojis:

go run main.go | pz -e

Query Base On A Level

You can make a query for a specific log level by adding -l log_level:

go run main.go | pz -l info

Query Base On A Timestamp

You can make a query for all logs of today by adding a -t today:

go run main.go | pz -t today

You can make a query for all logs which are generated from now on by adding a -t now:

go run main.go | pz -t now

You can make a query for all logs which are generated after a specific timestamp by adding a -t 123456789:

go run main.go | pz -t 123456789

Query Base On A Caller

You can make a query for a specific caller function by adding a -c caller:

go run main.go| pz -c authentication

Query Base On a Key-Value Pair

If your logs have key value pairs and you are looking for logs with a specific key-value pair, you can add a k key_1=value_1:

go run main.go| pz -k req_id="abcdef1234="
# or
go run main.go| pz -k req_id="abcdef1234=",uid=10230212
