What applications do you know of, that can reformat code?

Question

Hello,

I am looking for a list of code formatting and prettifying software; I have only found a few topics that all are language specific.

This is not about syntax highlighting!

If possible, I prefer lightweight, command-line, multiplatform, portable tools.
Nevertheless, if there is no interesting alternative, I also like to know what is available which does not meet those conditions.

Freely available software, and more particularly open-source software are also preferred.

Examples:

Ada

• SD Formatter (commercial)

C

• GNU Indent
• Astyle (multiplatform, command-line, free)
• Uncrustify (sample configuration file)
• SD Formatter (commercial)

C#

• Astyle
• Uncrustify (sample configuration file)
• SD Formatter (commercial)

C++

• Astyle
• Jindent (commercial)
• Uncrustify (sample configuration file)
• SD Formatter (commercial)

COBOL

• SD Formatter (commercial)

D

• Uncrustify (sample configuration file)

Delphi

• Jedi Code Format

Answer 1

For Java there exists Open source IDE IntelliJ idea that can easily format code.
It's not lightweight and not command-line. But multi-platform and free.

http://www.jetbrains.com/idea/free_java_ide.html

It supports Java, HTML and many others languages.

Answer 2

A very old but functional one is indent, on Unix, for C

Answer 3

Notepad++ is GUI rather than command-line, but it pretty-prints lots of languages.

Answer 4

JIndent (www.jindent.com) for Java and C/C++.

Jalopy (www.triemax.com) for Java.

Answer 5

NArrange - .NET Code Organizer/Formatter/Beautifier free, command line, supports mono too.

Answer 6

uncrustify is a very powerful and configurable open source utility for C and C++. A good front end GUI is also available for it (and many others... hint hint) called UniversalIndentGUI.

The power comes in how many formatting attributes it can be configured to adjust. The downside is it takes a couple of days of studying the hundreds of parameters and getting just the right combination for your preferred formatting style.

Once you have that config file, though, it is like a pocket full of gold.

Here is my config file: http://www.aximel.com/files/uncrustify.cfg

Answer 7

Perl has Perl::Tidy.

Answer 8

Our company, Semantic Designs, offers language specific code formatters for a wide variety of languages, including C, C++, C#, COBOL, Java, PHP, Javascript, Python, Fortran, Ada, VisualBasic and many others.

We in fact have such formatters for for the set of languages listed here, although many of them are not currently packaged directly for use by themselves.

Answer 9

I would like to add Tora that can reformat SQL (CTRL·SHIFT·ALT·I in editor window)

Answer 10

For Delphi:

• DelForExp, a freeware Pascal source code formatter for Delphi
• JEDI Code Format
• GExperts is a IDE plugin which also contains a code formatter.

Answer 11

ModelMaker for Delphi and C# is decent: http://www.modelmakertools.com/

Answer 12

The JetBrains Resharper Visual Studio addin does a lot of stuff, including code formatting. It's not lightweight, and it's not command line.

Answer 13

Within jEdit I've used a bunch of plugins: AStyle, Beauty, CheckStyle, Jalopy and JavaStyle

Answer 14

Definitely CTRL-K-D in Visual Studio to auto-format your code. This works with all code loaded in VS, including XML and ASPX file. I used this so much now that sometimes I unconsciously do that without thinking after editing aspx file.

• Ruby formatter
• PythonTidy

Answer 16
