Suppose you have got a bunch of files written in C, C++ or Fortran, by different authors, with different opinions on formatting, how to comment, and so on. I think many people know situations like these.

Are there any free tools for ends like:

• uniform format of code (ind开发者_如何学编程ent, etc.)
• create standard comment bodies
• rename variables

?

Have a look at AStyle. It's a command line based formatter/beautifier. It doesn't handle Fortran though it works with C, C++, C# and Java

---

You can have a look at the indent (unix) command. It doesn't do everything you are asking for , but that's a good start I think

For Fortran there is plusFORT, which can do much more than what you ask for, such as reorganizing code and translating from FORTRAN 77 to Fortran 90. See http://www.polyhedron.com/pf-plusfort0html and http://www.polyhedron.com/pflinux0html

The CDT Plugin for Eclipse has great formatting and refactoring tools for C/C++.

The formatter can be customized to fit almost all needs.

Also the refactoring tools are quite powerful and renaming variables, classes etc. is an easy and safe task with them. (They use the indexer/parser to recognize scope of variables, so its not a simple search and replace. Matching patterns within comments can be changed automatically, too).

However, as far as I know there is no batch processing possible.

Edit: Another - obvious - drawback is, that you have to create a project to make the indexer (and thus the refactoring tools) work. So at least you have to add all include paths and important compiler defines to project settings. I never tried, but the indexer should work fine without a real compiler available, but it may be necessary to make the project to use the "internal builder", otherwise you cannot set include paths. (I'm unsure about this, because I use the internal builder with gcc in my projects - this works fine.)

I've used Uncrustify with UniversalIndentGui for formatting C++ code. It works pretty well. Uncrustify offers many customization options and UniversalIndentGui "offers a live preview for setting the parameters of nearly any indenter. You change the value of a parameter and directly see how your reformatted code will look like."
