Git filter with cygwin sed on Windows

Question

I am trying to implement a basic string replacement in the header of my code with git filter clean feature.

Here is what I did so far:

I created a .gitattributes :

; Filters for .c, .h files
*.c filter=code_filters
*.h filter=code_filters

Then in my project config :

[filter "code_filters"]
    clean = sed.exe -e "s/Project\s*:.*/Project : My Current Project/"

Since I am on Windows, I use sed from cygwin which is in my path. The regular expression seems correct:

$ echo "Project :" | sed.exe -e "s/Project\s*:.*/Project : My Current Project/"
Project : My Current Project

Unfortunately, the filter syntax is not accepted. For any git command I get:

fatal: bad config file line 14 in .git/config

Could someone tell me what I am doing wrong here?

Note: I left the .exe extension to focus on the Windows aspect of my question. I'll remove it when it will work!

Answer 1

I got it working by escaping the / character so code looks like

[filter "code_filters"]
    clean = sed -e 's/Project\\s*:.*/Project : My Current Project/'
