I was looking into Drill's(open source github project) documentation to create a patch.
I came across this command:
git format-patch origin/master --stdout > DRILL-1234.1.patch.txt
I made some changes. I verified my changes by git status. I modified a .java file. I tried above-mentioned command to create a patch.
I opened DRILL-1234.1.patch.txt & its empty.
Then I tried git add <modified file> & tried the same command, still empty patch file.
What am I missing?
Git format-patch creates patches from commits. So you have to perform git commit first.
Also - I don't think --stdout does what you think it does.
From here: https://git-scm.com/docs/git-format-patch
The names of the output files are printed to standard output, unless the --stdout option is specified.
format-patch creates one patch file for each commit you have. It does not output the file itself, but the name of the patches files.
