Simple Logger - Probably the most beautiful logging library you've ever seen.
I had a very complex data flow to debug at work so I came up with this logging class to help me find even the most insidious bugs. I wanted a simple-to-use logging library that allowed me to build very clear log messages even from many places in the code.
Using SLogger is extremely easy. To create a log message in one place you can do like this:
SLogger.begin("myMethod")
.field("WHEN", "Today")
.field("LINE", "3")
.newLine()
.field("Nice Field", "Value")
.line("This is just a simple line in the log")
.print();This will produce the following log message:
┌───────────────────────────────────────┐
│ 21-09-2020 12:40:37 - myMethod │
├───────────────────────────────────────┤
│ WHEN: Today │
│ LINE: 3 │
│ │
│ Nice Field: Value │
│ This is just a simple line in the log │
└───────────────────────────────────────┘
For a more complex case in which you want to log data from multiple functions or points in your code you can do like this:
class MyClass {
SLogger logger;
void calledMethod() {
logger = logger.line("We now are in the 'calledMethod' method!")
.field("MyExampleField", "MyExampleValue");
}
void myMethod() {
logger = SLogger.begin("My Awesome Title")
.line("We are in the 'myMethod' method!")
.field("METHOD", "myMethod")
.newLine();
calledMethod();
logger.newLine()
.line("End of the execution.")
.print();
}
}This will produce the following log message:
┌──────────────────────────────────────────┐
│ 21-09-2020 12:47:16 - My Awesome Title │
├──────────────────────────────────────────┤
│ We are in the 'myMethod' method! │
│ METHOD: myMethod │
│ │
│ We now are in the 'calledMethod' method! │
│ MyExampleField: MyExampleValue │
│ │
│ End of the execution. │
└──────────────────────────────────────────┘
Optionally it can use log4j to log in production code, just use the log method instead of the print one.
