Color additives are used in foods for many reasons including: Under feudalism, aesthetic aspects were not considered, at least not by the vast majority of the generally very poor population. One of the very first food laws, created in Augsburg, Germany, inconcerned spices or colorants and required saffron counterfeiters to be burned. Analytical chemistry was still primitive and regulations few.

You could write a custom converter for this purpose, or simply make use of format modifiers just discussed to shorten the level value to a single character.

Conversion word options A conversion specifier can be followed by options. The are always declared between braces. We have already seen some of the possibilities offered by options, for instance in conjunction with the MDC conversion specifier, as in: A conversion specifier might have more than one option.

For example, a conversion specifier that makes use of evaluators, which will be covered soon, may add evaluator names to the option list, as shown below: For example, consider the next pattern. It replaces any sequence of 14, 15 or 16 digits contained in the message with XXXX effectively obfuscating credit card numbers.

Parentheses are special Coloring agent logback, parentheses within the pattern string are treated as grouping tokens. Thus, it is possible to group a sub-pattern and apply formatting directives on that sub-pattern.

As of version 0. If without the grouping the output was ContextListener - Classload hashcode is ContextListener - Initializing for ServletContext ContextListener - Trying platform Mbean server LoggingTask - Howdydy-diddly-ho - 0 NumberCruncherImpl - Beginning to factor.

NumberCruncherImpl - Trying 2 as a factor. NumberCruncherImpl - Found factor 2 The latter form is more comfortable to read.

If you need to treat the parenthesis character as a literal, it needs to be escaped by preceding each parenthesis with a backslash.

Coloring Grouping by parentheses as explained above allows coloring of sub-patterns. As of version 1. These conversion words are intended to contain a sub-pattern. Any sub-pattern enclosed by a coloring word will be output in the specified color.

Below is a configuration file illustrating coloring. This will output the logger name abbreviated to 15 characters in cyan.

TrivialMain - Finish off with fireworks It takes very few lines of code to create a coloring conversion word. The section entitled creating a custom conversion specifier discusses the steps necessary for registering a conversion word in your configuration file.

Evaluators As mentioned above, option lists come in handy when a conversion specifier is required to behave dynamically based on one or more EventEvaluator objects. EventEvaluator objects have the responsibility to determine whether a given logging event matches the criteria of the evaluator.

Let us review an example involving a EventEvaluator. The next configuration file outputs the logging events to the console, displaying date, thread, level, message and caller data. Given that extracting the caller data of a logging event is on the expensive side, we will do so only when the logging request originates from a specific logger, and when the message contains a certain string.

Thus, we make sure that only specific logging requests will have their caller information generated and displayed. In other cases, where the caller data is superfluous, we will not penalize application performance.

Evaluators and in particular evaluation expressions are presented in a dedicated section of the chapter on filters which you MUST read if you want to use evaluators in any meaningful way.

Also note that the examples below are implicitly based on JaninoEventEvaluator which requires the Janino library. Please see the corresponding section of the setup document. The following class makes use of some of the characteristics mentioned in above configuration file. Five logging requests are issued, the third one emitting the message "who calls thee?

Only the third logging event matches the evaluation criteria, causing its caller data to be displayed. For other logging events, the evaluation criteria do not match and no caller data is printed.Product Description color matching agents that blend with polyester resins, epoxy resins.
