Developers and any user looking for a code comparison tool, beautifier, minifier, and parser solution
About Pretty Diff
Pretty Diff is a language-aware code comparison tool, beautifier, minifier, and parser for a variety of languages. Pretty Diff was created to compare code samples for various languages regardless of differences in comments, white space, and other factors. Currently, the project operates by beautifying code and then comparing the beautified product of the code samples. The goal in a future version is to introduce the comparison step directly into the beautifiers between the parse step and the beautification step to become a truly language-aware code comparison and analysis tool. The code comparison mode is the default mode and the only mode to require two code samples. Pretty Diff has progressively moved from community-driven dependencies to custom parsers to accomplish code beautification for a diversity of features and requests. Each of Pretty Diff's beautification libraries has a minify feature.
