How to patch on Windows?


Thanks to Macke, a good way to apply a patch file under Windows OS is using Git.As I understood, Git is a version control solution like SVN.

Here is a guideline to apply a patch :

  • First of all, download the latest release of the Windows Git Edition here :GIT
  • With the cmd prompt, change directory to the patch file and files to patch
  • Now you can use the following command line :
git apply --ignore-space-change --ignore-whitespace --whitespace=nowarn file.patch

Simple isn't it ?

Thank you Macke


Not that since Git 2.3.3 (March 2015), you can use git apply --unsafe-paths to use git apply outside a git repo.

See commit 5244a31 by Junio C Hamano (gitster)

"git apply" was not very careful about reading from, removing, updating and creating paths outside the working tree (under --index/--cached) or the current directory (when used as a replacement for GNU patch).

The documentation now includes:

--unsafe-paths:

By default, a patch that affects outside the working area (either a Git controlled working tree, or the current working directory when "git apply" is used as a replacement of GNU patch) is rejected as a mistake (or a mischief).

When git apply is used as a "better GNU patch", the user can pass the --unsafe-paths option to override this safety check.
This option has no effect when --index or --cached is in use.

So if you have git installed, git apply could help, even outside of any git repo.
