Over 61k times now, so about 4k views in the last month. Yes, definitely not a constructive question. — Paul, Apr 02 '13 at 13:50
Not sure why this topic was closed, but http://tohtml.com/javaProperties/ worked well for me. The styles and color are "inline" which makes it very simple to copy and paste into something else. — Andrew Bucklin, May 19 '13 at 16:30

Did you actually try this one? It outputs `>` for `>` and similar. – Ponkadoodle May 10 '11 at 02:27
I think that is because those will be embedded inside another html page, as a sample, etc, and really should be. – Andrew Nov 02 '11 at 10:24
It outputs < for `<`... – Mar 09 '13 at 16:59

What language?? There are different tools for almost every imaginable programming language, since they all have different syntactic rules and conventions.

Good ol' indent is a nice, customizable, command-line utility to format C and C++ programs.

Since the question asked for "online beautifier", do you know of any Web frontends to indent? – Anm Aug 10 '12 at 04:48

It depends of the language, and of the architecture you are using.

alt text

For example, in a php platform, you can format almost language with GeSHi

As bluish comments, GeSHi is a generic syntax highlighter, with no beautification feature. It is more used on the server side, and combine it with a beautification tool can be tricky, as illustrated with this GeSHi drupal ticket.

Use gist.github.com. There is a multi-language support(java, c, c++, c#, vb, haskell, ruby, javascript, lua, HTML, SQL, Tcl, Perl, JSON, groovy...)

Here is a sample "Generate LiquiBase changeLogs using Groovy"

that is correct, it is a code beautifier and code snippets storage. It has some cool features (like share, star and private snippets). – rayyildiz Nov 16 '12 at 06:51
