Java code formatter code#
In HTML or XML code you probably need '' more often than, so it doesn’t matter that cannot be displayed. allows the use of (escaped using HTML number codes), which you need for Java code containing annotations. For inline snippets, it doesn’t matter that line breaks are lost.įor multi-line snippets you need line breaks. }, you don’t need to escape special characters. The following guidelines can be derived for different situations: Situation Which option to use depends on the content of the code snippet you want Looking at the table above, sadly, there is no single best option. The following table summarizes the different javadoc code markup …}Įscape special characters via HTML number codes Jindent empowers you to transform any foreign Java/C/C++ source code to meet your preferred. Renders an unwanted whitespace before the character, which is why I don’t discuss that optionĪny further. Jindent is a powerful source code formatter for Java, C and C++. Note that you actually CAN escape an using within the block. CANNOT be escaped with HTML code, though!

Autodetect HTML XML CSS JavaScript PHP JSON. Time saving JavaScript formatter that helps you to concentrate on the most important aspects of your project. In the rendered Javadoc HTML so they have to be escaped. Paste your JavaScript in the tool and get a clean code for time saving and increased ease of editing. So none of these characters will be displayed correctly Since we’re in a Javadoc environment, is evaluated as a Javadoc tag and since we’re also in an HTMLĮnvironment, '' are evaluated as HTML tags. Thus, line breaks and indentation are supported. This means that HTML renderers by default know that theĬode within the tag should be displayed literally. is the default HTML tag for preformatted text. Select 'Format Document With.' or 'Format Document' if this formatter is the only Java formatter installed. For one time use:-Open the Command Palette (ctrl+shift+p).
This is important for Java code containing annotations.Ĭan special characters like the ones above be escaped using HTML number codes like <, > and (which evaluate to '' and the special characters cannot be displayed literally, they should at least be escapable via HTML codes. A formatter for Java files that uses the Prettier formatter.Is displayed correctly in the rendered should not be evaluated as part of a Javadoc tag but instead be displayed literally. This is especially important for code snippets containing HTML or XML code or Java code containing generics. ''should not be evaluated as part of an HTML tag but instead be displayed literally. To assemble a definitive guide on when to use which of the markup features, I took a look at how theyīehave by answering the following questions for each of them: QuestionĪre indentations and line breaks displayed correctly in the rendered Javadoc?įor multi-line code snippets indentations and line breaks are essential, so they must not get lost when rendering the Javadoc.Īre '' displayed correctly in the rendered Javadoc? Into a Javadoc comment, I’m wondering which of the three to use and what the difference

Javadoc supports three different features for code markup. Since there are multiple options to do this - each with different results - this blog post givesĪn overview on these options and a guideline on when to use which. In the final Javadoc HTML, especially when special characters like '' and are involved?
