Things that don't work out of the box:

• Directory tree operations (Partly*)
• Version control specific properties
• Non-unified diff formats
• You can use it to patch files in directory with same name of patched ones and add files ("--- /dev/null")

python3 -m patcher diff.patch

or

patcher diff.patch

For more instructions, run

python3 -m patcher --help

You can install from this repository:

After (may be) it will be on PyPI
