Adding full directory via diff & patch

Is it possible to add a full directory via diff and patch?

It seems as very convenien开发者_开发问答t way to add additional modules on top of standard code-base.

I googled for some solutions, but they generally work on file level, not on directory level.

Thanks.

Answering myself:

diff -urPp old_dir/ new_dir/ > new_module.patch

Seems to do the trick.

Two quick suggestions--these should help

1. You need the flag -r | --recursive

2. You probably also need --unidirectional-new-file or -N | --new-file.

as I have done what you have in mind here.

Below steps will work

1. Taking patch between the old source code and new source code (new files + new directories) diff -urPp old_src new_src > new.patch  
2. create a temp directory mkdir temp  
3. copy the original old source code directory to temp directory cp -r old_src temp  
4. copy the patch file to temp directory created cp new.patch temp  
5. change directory cd temp  
6. apply patch patch -p0 < new.patch  

Now all the patches would be applied with file changes + new files + directory addition in the temp directory
