Smashing Magazine - we smash you with the information that will make your life easier. really.

Well-documented and readable source code is essential for every collaborative project. Logically structured, well organized and nicely formatted, the code can speed up the bug hunting and help to keep the code clean, minimal and still functional. These aspects are particularly important if the code is being developed by a group of developers: in this context a common scheme for source code presentation is necessary. You don’t have to do everything by hand; in fact, there are many tools which can save a lot of time – for you and your co-workers.

The tools and services we’ve collected below aren’t validators. They format and beautify the code; some of them can remove redundant elements. Using them, you have to make sure you have a backup, so your data can always be restored.

Let’s take a look at code beautifier and formatter which can save you a lot of time and help to maintain a clean and readable source code.

Code Beautifier And Formatter

1. Quick Highlighter
Quick Highlighter can format source codes written in over 85 languages – among them C++, PHP, Ruby, HTML, JavaScript, Perl, Python, Smarty, XML and more. The tool formats source code and highlights inbuilt keywords, data types etc.

2. PrettyPrinter
Knows PHP, Java, C++, C, Perl, JavaScript, CSS. The service offers many formatting options you can use to present the code just the way you’d like it to look like.

3. PHP Code Beautifier
This tool is designed to beautify PHP code, applying most of the PEAR standard requirements to it. It can even process really scrambled scripts, e.g. all code in one line, and thus may help you to get scripts into a more readable form. It sets missing line breaks without removing any additional line breaks that you may use to group related things and corrects wrong indentation according to the level of nested braces.

4. Ruby Script Beautifier
Ruby Beautifier accepts a command-line list of file names, creates a backup copy of each named file and beautifies the originals. If there is an indentation error (an imbalance of opening and closing keywords), the script will print an error message but will save the result anyway.

5. Tabifier
The tabifier is a tool to properly indent computer code. The style it produces is a mix of my personal preferences for indentation plus what I could manage to make a program produce from dirty source. The tabifier currently supports CSS, HTML, and C Style code; the latter being anything that uses curly braces to start and end blocks, and semicolons to terminate statements.

6. CSS Beautifier
This tool offers a variety of options, among them – Alphabetizing Feature and De-Capitalization Feature.

7. CSS Formatierer und Optimierer
Has different compression layouts; you can sort selectors, properties, regroup selectors, optimize shorthands, compress colors, compress font-weight, discard invalid properties and add timestamps. You can also create a custom template the system will use to format the code. The result can be outputted as a file. A copy / mirror of the tool can be found on cleancss.com.

8. Highlight.js
Highlight.js highlights syntax in code examples on blogs, forums and in fact on any web pages. It’s very easy to use because it works automatically: finds blocks of code, detects a language, highlights it. Also available as Wordpress-Plugin and Firefox-extension. Suported languages: Python, Ruby, Perl, PHP, HTML, CSS, Django, JavaScript, VBScript, Delphi, Java, C++, SQL. Similar tools is offered by Google: Googles Javascript Code Prettifier.

9. Code Beautifier Plus

10. PHP Formatter
PHP formatter adds comments after control structures, colors the output, links to the php-manual by inline-functions, removes comments and removes empty lines. There are 5 pre-defined layouts, but you can also define your own styles.

11. PHP_Beautifier

13. Lorins simple code beautifier for C++, C#, Java, and Javascript
