# bash script for deploying hugo site to github pages.

# I have a two branch develop and master.
# develop branch keeps source files of my blog
# master branch keeps generated website files
# If you have unstaged or not tracked files, script adds these files to stash.
# So you unstash these changes after deploy.

if [[ $(git diff --name-only) ]]; then
    echo 'Commit or stash changes before deploy.'
    echo 'Untracked files will be stash automatically.'
    exit 1
fi

_untracked_files_exist=0
if [[ $(git ls-files -o --exclude-standard) ]]; then
    # stash all untracked files if exist
    git stash save -u
    _untracked_files_exist=1
fi

# Generate site
hugo -d public

# move generated files to /tmp
rm -rf /tmp/public
mv public /tmp

git checkout master

# Remove all files in master branch
rm -rf `pwd`/*

# Move all generated files from public directory to here
mv /tmp/public/* .
rm -r /tmp/public/

# Add new created files.
git add .
git commit -m 'Site updated'
git push

# Go back develop branch and pop changes from stash
git checkout -

# If stashed untracked files exist, pop them
if [[ $_untracked_files_exist -eq "1" ]]; then
    git stash pop
    git reset .

I accidentally ran this script and I think It may have deleted some files! Is there a way to undo this?

@akufta the script stashes all changed files and not tracked files. So look at stash for files.
Are you have only master branch? If so this should be couse to error.
I am using master for keeping generated files and develop for keeping posts. I am running this script on develop branch.
