Introduction
Do you know what Cinder is? An open-source programming toolkit called Cinder provides the C++ language with powerful visualization capabilities. It is often used for creative coding. Cinder is cross-platform,with official support for macOS, Windows, Linux, iOS, and Windows UWP.
Logging in Cinder
A variety of easy-to-use and flexible logging techniques are available with Cinder logging, which is a component of the ci::log namespace. Logging in Cinder aims to provide platform users access to core, integrated functionality that will handle the bulk of real-world use cases instead of avoiding specialized logging packages.
The default LoggerConsole is enabled in all Cinder apps, which means that the application console window will show any logging requests made by Cinder. To confirm this, we will make a logging call in the new cinder app this way.
CI_LOG_D( "Hello Ninjas!" );
The application console will show the trace that is produced
You can produce any additional loggers this way by logging in Cinder. Make sure that the calls you make are concise and flexible.
Log Levels
An essential stage in log management is creating appropriate log levels. Logging levels enable team members who access and read logs to comprehend the relevance of the message they see in the log or while using observability tools.
ci::log:: Level specifies common logging levels. It is up to the developer to decide how to use each logging level precisely because opinions on this subject are divided. LEVEL VERBOSE is the lowest logging level, and LEVEL FATAL is the highest. Knowledge of this thing is important while understanding logging in Cinder. The supported logging levels and associated functions are shown below:
Level
Function
Enum Value
Comment
LEVEL_VERBOSE
CI_LOG_V
0
(lowest logging level)
LEVEL_DEBUG
CI_LOG_D
1
LEVEL_INFO
CI_LOG_I
2
LEVEL_WARNING
CI_LOG_W
3
LEVEL_ERROR
CI_LOG_E
4
LEVEL_FATAL
CI_LOG_F
5
(highest logging level)
Logger Types
Logger- The root class for all loggers is called Logger. This class is never directly utilized.
LoggerConsole- The application console window receives log messages from LoggerConsole. This logger is always turned on. It doesn't accept any inputs.
LoggerFile- Log messages are sent to a specific file using LoggerFile.
LoggerFileRotating- Log messages are directed to a certain file using LoggerFileRotating. When the programme starts up for the first time, and the first logging call occurs after midnight, the name of that file is examined.
LoggerBreakpoint- Instead of logging messages, LoggerBreakpoint sets a breakpoint when a certain threshold of log events is exceeded. The trigger level specifies the lowest logging level at which execution will fail.
LoggerSystem- The platform-specific system log will receive log messages from LoggerSystem.
Logger Management
Multiple logger kinds are useless during logging in Cinder if loggers can't be readily created, enabled, and disabled. All active loggers are managed in a stack by ci::log::LogManager, which also offers tools to make logger administration easier.
Compile Time Settings and Optimization
You may set the minimum level of logging in cinder enabled using the CI_MIN_LOG_LEVEL directive. For instance, suppose you added the following code to your main application:
Then LEVEL_WARNING would be the lowest authorized level of logging. Due to the method's compile-time optimization, calls to lesser logging levels, such as CI_LOG_D, would not be subject to runtime expenses.
All logging levels are available by default when building your programme in debug mode.
By default, all levels up to and including LEVEL_INFO are supported when generating your programme in release mode.
These default values are overwritten when you set the CI_MIN_LOG_LEVEL variable.
Frequently Asked Questions
What is Cinder?
An open-source library called Cinder was created to enhance the C++ language's capability for advanced visualization. It can be seen in many ways as a C++-based substitute for tools like the Java-based Processing library, Microsoft Silverlight, or Adobe Flash.
What language is Cinder present in?
Cinder is a framework present in the C++ programming language.
What is the Cinder framework?
One of the most intriguing frameworks for creative coding is Cinder. It is made in C++ for improved performance and enables rapid development of interactive applications with complex visuals.
What are the different categories in the Cinder framework?
The categories include computational geometry, maths, audio, video, images, and graphics.
What is creative coding?
Software, code, and computational processes are used in creative coding to express oneself or produce works of art. Creative coding is considered to be more aesthetic than functional.
