![]() This is based on Eclipse 3.6 Helios distribution. ("! I did not format this is based on the post here:Īs I do not know how long the link will stay up, I will describe the contents below. ![]() There is a shell script that uses a bundled OpenMRSCodeFormatter.xml file. It is Java-only, command line, and should be cross platform compatible: Here is something that I made using Eclipse 3.6 jars. Or convert any XML exported formatter file with:Ĭat formatter.xml | grep setting | sed > formatter.asprefs The OpenMRSFormatter.xml file actually has to be a preferences file and not an XML file. UPDATE: Per my new understanding based on an incorrect bug report I filed: I want a tool that I can run locally.įinally, solutions need not be restricted to open source, public domain, shareware, free software, commercial, or anything else. I'm also not interested in a web service. I suppose it might be nice for a solution to have support for languages other than Java, but that is not a requirement.įurthermore, tools that only perform code highlighting are right out. I'm also not necessarily interested in a grand-unified formatter for many languages. I want to be able to specify my own style, not simply select from a preset list.Īlso, I'm not looking for a general purpose pretty-printer written in Java that can pretty-print many things. Read Source Code → Apply Styling Rules → Write Rule Violations Style Checker (does not produce modified source code) Read Source Code → Apply Styling Rules → Write Styled Source Code So the picture looks like this:įormatter (produces modified source code that conforms to styling rules) ![]() A style checker also applies styling rules, but it simply reports rule violations without producing modified source code as output. Very little, if any, other refactoring is performed. Syntactic modifications are limited to things like modifying code layout as in changing whitespace, or organizing import statements. To be clear, a "formatter" (or "beautifier") is not the same as a "style checker." A formatter accepts source code as input, applies styling rules, and produces styled source code that is semantically equivalent to the original source code. A formatter written in closed-source C/C++ that only runs on, say, Windows is not ideal, but is somewhat interesting. So, a built-in formatter for the IDE du jour is of little interest here (unless that IDE supports batch mode formatter invocation, perhaps from the command line). Ideally, it should be independent of any particular operating system as well. The formatter must be stand-alone, that is, it must support a "batch" mode that is decoupled from any particular development environment. It could even be used inside a browser.I'm interested in learning about the available choices of high-quality, stand-alone source code formatters for Java. Prettier-java has no additional runtime pre-requisites (e.g: Python executable). What this means is that unlike many other Prettier plugins, Prettier-Java uses a Java-Parser implemented in JavaScript using theĬhevrotain Parser Building Toolkit for JavaScript. Into a traversable data structure (Usually an Abstract Syntax Tree)Īnd then print out that data structure in a "pretty" style. How it worksĪ Prettier plugin must first parse the source code of the target language It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary. Prettier is an opinionated code formatter.
