git pre-commit hook: changed files are not in the current commit

Question

I have a git pre-commit hook which changes some files if they are corrupt. After the hook is done the changed files are not listed in the current commit. How can I stage the changes from the hook into the current commit?

My hook looks like this:

#!/bin/sh
versionUpdater -editVersion

Which opens a windows forms where I can edit some versions from some files. After I finished editing I want that these changes are in the current commit.

Those changes from the hook are now listed in the next commit.

There are several options. the following answer will explain in details what needs to be done and how.

Can a Git hook automatically add files to the commit? .

In the pre-commit:

• Touch a file .processCommit or something. (be sure to add this to .gitignore)

#!/bin/sh 
echo 
touch .processCommit 
exit

In the post-commit:

if .processCommit exists you know a commit has just taken place.

#!/bin/sh
echo
if [ -a .commit ]
    then
    rm .commit
    git add yourfile
    git commit --amend -C HEAD --no-verify
fi
exit
