Can I change the color of a line of text in a Java Eclipse editor based on its contents?

Question

In particular, for editing Java code, I wanted to know if I can change the text color of any line of code starting with the LOG. line LOG. which indicates the logging statement.

In this example, I would like the LOG operator to display everything in gray, for example. This would help in reading code that was pretty much logged.

 public class Foo { private static final Logger LOG = LoggerFactory.getLogger(Foo.class); public void doSomething() { LOG.info("About to do something"); // code } } 

This is probably harder than just identifying a single line, since logging can be split into multiple lines and / or even contained in an if(LOG.isDebugEnabled) {...} block.

Visualy I would like these LOG statements / blocks to display as the default coloring // comments / * * /

You can achieve this by writing a custom eclipse plugin.
Eclipse works to color syntax according to the rule.

 ITokenScanner scanner = new RuleBasedScanner(); IToken string = createToken(colorString); IRule[] rules = new IRule[3]; // Add rule for double quotes rules[0] = new SingleLineRule("\"", "\"", string, '\\'); // Add a rule for single quotes rules[1] = new SingleLineRule("'", "'", string, '\\'); // Add generic whitespace rule. rules[2] = new WhitespaceRule(whitespaceDetector); scanner.setRules(rules); scanner.setDefaultReturnToken(createToken(colorTag)); 

The createToken method creates a Token object for a specific color:

 private IToken createToken(Color color) { return new Token(new TextAttribute(color)); } 

To continue, you can refer to the Eclipse FAQ.

One possibility is to use the file search tool and search the text that you want to highlight.

If you search for, for example, *LOG.* , You will get a search result across the entire string.

You can access the file search tool by selecting a piece of text in the editor and press Ctrl + H You can also easily search for all files in a project or in a subdirectory.

In Eclipse, you can also customize the look of your search result to see how you want it. You do this in Window > Preferences > General > Editors > Text Editors > Annotations > Search Results .

As a result, the result *.getLogger()* :
