Git Ignoring Files and Folders Ignoring only part of a file [stub]
Example
Sometimes you may want to have local changes in a file you don't want to commit or publish. Ideally local settings should be concentrated in a separate file that can be placed into .gitignore, but sometimes as a short-term solution it can be helpful to have something local in a checked-in file.
You can make Git "unsee" those lines using clean filter. They won't even show up in diffs.
Suppose here is snippet from file file1.c:
struct settings s;
s.host = "localhost";
s.port = 5653;
s.auth = 1;
s.port = 15653; // NOCOMMIT
s.debug = 1; // NOCOMMIT
s.auth = 0; // NOCOMMIT
You don't want to publish NOCOMMIT lines anywhere.
Create "nocommit" filter by adding this to Git config file like .git/config:
[filter "nocommit"]
clean=grep -v NOCOMMIT
Add (or create) this to .git/info/attributes or .gitmodules:
file1.c filter=nocommit
And your NOCOMMIT lines are hidden from Git.
Caveats:
- Using clean filter slows down processing of files, especially on Windows.
- The ignored line may disappear from file when Git updates it. It can be counteracted with a smudge filter, but it is trickier.
- Not tested on Windows
