问题
I want git diff to not show BOM changes.
Such changes typically show up as <feff> in the diff:
-<feff>/*^M
+/*^M
How can I make git diff to behave this way?
Preferably with a command-line parameter.
git --ignore-all-space (aka git -w) does not do the trick.
I am on Mac OS X if that matters.
回答1:
Use Git Attributes filter
One possible solution would be to create a BOM filter such as:
#!/bin/bash
sed '1s/^\xEF\xBB\xBF//' "$1"
store it somewhere in your path (as i.e. removebom) and make it executable.
Then you need to configure the filter in Git by running:
$ git config diff.removebom.textconv removebom
and adding an attribute for files you are interested in (i.e. cpp) to your repository:
*.cpp diff=removebom
as a .gitattributes file.

Or remove the BOM once for all
... because, hopefully, the BOM may be removed once and for all in your project :)
