![]() ![]() Special characters can be escaped with a backslash so they won't be interpreted as wildcard patterns. Matches any integer numbers between num1 and num2, where num1 and num2 can be either positive or negative Matches any of the strings given (separated by commas) ( Available since EditorConfig Core 0.11.0) Matches any string of characters, except path separators ( /) Special characters recognized in section names for wildcard matching: * EditorConfig files are read top to bottom and the most recent rules found take precedence.įilepath glob patterns and currently-supported EditorConfig properties are explained below. EditorConfig files should be UTF-8 encoded, with either CRLF or LF line separators. Only forward slashes ( /, not backslashes) are used as path separators and octothorpes ( #) or semicolons ( ) are used for comments. The section names are filepath globs (case sensitive), similar to the format accepted by gitignore. ![]() File Format DetailsĮditorConfig files use an INI format that is compatible with the format used by Python ConfigParser Library, but are allowed in the section names. (note the trailing dot), which Windows Explorer will automatically rename to. ![]() editorconfig file within Windows Explorer, you need to create a file named. Properties from matching EditorConfig sections are applied in the order they were read, so properties in closer files take precedence.įor Windows Users: To create an. editorconfig files will stop if the root filepath is reached or an EditorConfig file with root=true is found.ĮditorConfig files are read top to bottom and the most recent rules found take precedence. editorconfig in the directory of the opened file and in every parent directory. When opening a file, EditorConfig plugins look for a file named. indent_style = space indent_size = 2Ĭheck the Wiki for some real-world examples of projects using EditorConfig files. end_of_line = lf insert_final_newline = true # Matches multiple files with brace expansion notation This inspection was around in IntelliJ IDEA 2016.2, but has been updated in 2016.3 – not only with the ability to turn on or off the suggestion to use forEach, but also to provide better alternatives to refactor to, and suggest new places that can use the Streams API.īy better alternatives, I mean that IntelliJ IDEA has become even smarter with how it refactors code.Root = true # Unix-style newlines with a newline ending every file This is covered in more detail in the Migrating to Java 8 Tutorial. This inspection “foreach loop can be collapsed” identifies numerous places which use a traditional for loop but suggests a number of different alternatives to replace it with, including forEach (with and without the Streams API), and collect. My preference is to inline variables where they’re not really adding anything (sometimes variable names are useful to document intermediate steps, but that’s not really necessary in this case), so the code simplifies further if you use Ctrl + Alt + N on the variable: reflections.getTypesAnnotatedWith(Entity.class).forEach(m::map) If you apply the change, the code is simplified to use the forEach() method from Iterable, since Set implements Iterable: final Set> entities = reflections.getTypesAnnotatedWith(Entity.class) For example, IntelliJ IDEA will only give a warning about the code below if this checkbox is ticked: final Set> entities = reflections.getTypesAnnotatedWith(Entity.class) Which means code that originally was highlighted by this inspection when using 2016.2 may not be flagged in 2016.3 if you haven’t selected the checkbox. We’ll look at a few of them in a bit more detail.įirstly, in IntelliJ IDEA 2016.3 note that the “foreach loop can be collapsed with Stream API” inspection has been updated - see the checkbox in the bottom right? “Suggest to replace with forEach or forEachOrdered”?īy default, this is not ticked. The specific code that I highlight, but they’re all valuable for locating areas of code that canīe migrated to Java 8. Here are the inspections that I’ve turned on for the presentation. Let’s take a look at which inspections are used, how you configure them, and go into detail about what some of them do. I’ve updated the presentation to use these new inspections, and performance tested the results when applied to a specific codebase. Identifying areas of code that can utilize Java 8 idioms and APIs, and making better use of those areas that already use Java 8. I’m revisiting the topic now that IntelliJ IDEA 2016.3 has added even more support for I’ve also written before about how IntelliJ IDEA can help you write more idiomatic Java 8 code. The initial version of this, the one I gave at DevoxxUK (video), is based on my Migrating to Java 8 Tutorial. I’ve been giving a talk this year showcasing how to use IntelliJ IDEA inspections to help you refactor existing code to Java 8. ![]()
