How to check code indentation?

How to check code indentation?

[Victor Porton]

I have a source code where some declarations or statements are indented 
wrongly. An example:

   function raptor_namespaces_find_namespace (Stack: Namespace_Stack_Handle;
                                                Prefix: chars_ptr;
                                                Len: int)
                                                return Namespace_Handle
     with Import, Convention=>C;

("Prefix" is not below "Stack" but two spaces are extraneous.)

I use -gnaty3 but weirdly GNAT 7.2.0 does not detect this error.

Is there any free tool to check (or even better automatically correct) Ada 
(preferably Ada2012) indentation?

There are reformatters, like:
  - ICCFMT: http://www.irvine.com/freebies.html
  - the reformatter tool in AdaGIDE: https://sf.net/projects/adagide
...and probably others.
If you want to check the before vs. after states to be sure nothing got lost on the way, the Normalize tool can be helpful:

I need Ada2012 support. It does not.

It is for Windows. I am a Linux user.

It doesn't help in my task.

Hm, GNAT GPS does (however sometimes wrong) Ada code reformatting when 
pressing Tab key.

Can it be scripted in some way to do Ada reformatting automatically for a 
set of source files?

Have you looked at gnatpp command?

Thanks, I am now checking it.

But it seems not to work :-(

Consider this short file test.ads:

  package test is
    end test;

I run /usr/local/stow/gnat-gpl-2017-x86_64-linux-bin/bin/gnatpp -i3 test.ads

There is no output and the file is not changed, it's wrong alignment 
remains.

What is wrong?

Oh, I see it works if I add -r option.

Emacs Ada mode does indentation, with full Ada 2012 support.

With a little elisp programming, you can use it for both test and fix.

The simplest way to test is to save the file to a different name, indent, and diff.

Use GPS with the plugin Autoformat enable then the file will be 
formatted every time its saved to disk.
