The second part it's about how under Vim it's possible to create some pre-packed files with some boring code and being able to just replace some key parts with some script, for example when creating a new C++ class I need the usual set of boring methods and ctors and the only thing that changes most of the time it's just the name of the class, so I would like to spend less time coding this repetitive portions of the code and kinda template and script the code generation for my source files

There are various solutions for templates on vim.org.

Have you tried UltiSnips, which supports templates from various different templating solutions?

It looks from the description of astyle, that you should just be able to use astyle still, automatically as you type in Vim.

See :help 'formatprg' and :help 'formatoptions'.

You have autoindent turned on twice, and smartindent (which I would recommend NOT using, it's not smart at all), and also cindent. cindent will override all the previous ones.

Additionally, normally you don't turn cindent on in your .vimrc.

Instead, right before your "syntax on" command, put:

filetype indent on

or

filetype plugin indent on

This will turn on Vim's smart filetype-based indenting.

If you want to use astyle you may not want to put the "indent" in there however, or you could override it for C/C++ code using the "after" directory (:help after-directory).

Now i have

but I got nothing out of this formatpgr, it's like nothing changed, not even with gg=G, I don't know where to look anymore, vim still uses the old formatting tool, it's supposed to be ok as far as I know.

[arj...@gmail.com]

looks ok, but apparently doesn't have 1 feature that I would like to have, for example after editing and adding several snippets to different files in different times, I would like to have the ability to go back and change a value for all the files in a single command, apparently after adding this snippets there is plain text and you can't really go back and pretend to re-edit things in a scripted way.

thanks, that documentation looks oddly paginated and not that easy to read, there is an rst version or a pdf one ? There is a more specific C++ plugin maybe with C++11 support ? I don't care about C.

After you edit your cpp file, are things set as you expect?

:verbose set formatprg? formatexpr? filetype? formatoptions?

The 'formatprg' option does not do automatic formatting unless the
'a' flag of 'formatoptions' is set, which I would not recommend in
this case. Further, the = command uses 'equalprg', not 'formatprg'.

So, to format your code using astyle as the 'formatprg', you will
need to manually reformat sections as you go with gq, not =.

Alternatively, you could set 'equalprg' to astyle, then use the =
command.

I think the behavior may be different between using astyle as the
'formatprg' vs. the 'equalprg', but I don't know what it is off the
top of my head.
