zprint is a highly configurable code formatter and pretty-printing library for Clojure and ClojureScript. It can reformat source code, Clojure data structures and EDN expressions using a wide range of formatting conventions.
The program goes beyond correcting indentation. It examines the structure of expressions and determines how lists, vectors, maps, sets and other forms should be arranged to improve readability. Its formatting engine provides extensive control over line wrapping, spacing, alignment and the treatment of comments.
zprint offers predefined styles for common formatting preferences, allowing developers to change its behaviour without constructing complicated configurations. More demanding users can customise individual formatting rules or combine styles to produce their preferred layout.
The formatter can be used from the command line, within the Clojure REPL or as a library embedded in other applications.
This is free and open source software.
