Comment Reflower is a Plugin for Visual Studio 2003 and 2005 to reflow the text in comments in source files to have even word wrapping. It does more than simply just wrapping all text in comment blocks. It attempts to recognise and wrap appropriately:
The results are best seen by example. ExampleFile.cpp is a sample file before Comment Reflower has been applied, ExampleFileAfter.cpp is the much neater and more readable result.
Comment Reflower is language neutral in implementation, and comes with initial settings to handle all the comment block types within C++/ C# and Visual Basic files, as well as settings to handle a number of common bullet points and all the Doxygen tag styles. However Comment Reflower is also fully configurable, so support for new languange types is easily added via the configuration GUI, shown below.
The current release is Version 1.4 and it can be downloaded from here.
