Re: [edk2-devel] [edk2 Patch 1/1] BaseTools: Syntax warning invalid escape sequence \C

["Jayaprakash, N" <n.jayaprakash@intel.com>]

Thanks Pedro.

I thought about using / instead of \\ but in many places, the path separator \\ is still used across the code.
But after looking at the usage of path separator in other parts of the code. I decided to go with \\.

For example:
In the same file:
2953 : MakeApp = MakeApp + '%s\\PcdValueCommon.c : %s\n' % (self.OutputPath, PcdValueCommonPath)

2842: if sys.platform == "win32":
            MakeApp = MakeApp + 'APPFILE = %s\\%s.exe\n' % (self.OutputPath, PcdValueInitName) + 'APPNAME = %s\n' % (PcdValueInitName) + 'OBJECTS = %s\\%s.obj %s.obj\n' % (self.OutputPath, PcdValueInitName, os.path.join(self.OutputPath, PcdValueCommonName)) + 'INC = '

Hence to align with the usage of path separator for "win32", I have used the \\ instead of /.

Hope this is fine.

Regards,
JP

AIUI, changing the \ to / would also work (and it would be prettier/more readable), since we're calling normpath right after.
