Creating unreleased changes file.

Its always a boring thing to create a change log file for the branch in unreleased_changes. Here is a git hook for the same. Just create a file in

 .git/hooks/post-checkout

and paste the following content in the same.

  #!/bin/sh
  # This is a git hook for unreleased changes file creation. Whenever you switch to any branch. If unreleased changes don't have change log file for that branch. This hook will create one for you and copy the sample content to it. Release and master will not have unreleased_changes file

  # --- Command line

  branch=$(git branch | sed -n -e 's/^\* \(.*\)/\1/p')

  if [ "$branch" == "release" ]; then
    echo "Woohoo.. Seems like new code is going live. :)"

  elif [ "$branch" == "master" ]; then
      echo "Starting a new feature? Create a branch :)"

  elif [ ! -f "$PWD/unreleased_changes/$branch.md" ]; then
      echo "UnReleased Changes File not found! Creating One from Sample"
    cp "$PWD/unreleased_changes/sample_example.md" "$PWD/unreleased_changes/$branch.md"
  fi

Give executable permissions to your hook.

chmod +x .git/hooks/post-checkout

Running bundle install and rake db:migrate

Its always a pain to bundle install or rake db:migrate or rake data:migrate after merging a branch. Its better to automate this thing using git hooks. Here is the git hooks for the same. Just create a file ie:

.git/hooks/post-merge

and paste the following content in the same.

#!/bin/bash

if [ ! -z `git diff --name-only HEAD@{1}..HEAD Gemfile` ]
then
  echo -e "\033[0;31m*** Gemfile change detected, running bundle install ***\033[0m"
  bundle install
fi

if [ ! -z `git diff --name-only HEAD@{1}..HEAD db/migrate` ]
then
  echo -e "\033[0;31m*** Migration changes detected, running rake db:migrate ***\033[0m"
  rake db:migrate
fi

if [ ! -z `git diff --name-only HEAD@{1}..HEAD db/data` ]
then
  echo -e "\033[0;31m*** Data Migration changes detected, running rake data:migrate ***\033[0m"
  rake data:migrate
fi

Give executable permissions to your hook.

chmod +x .git/hooks/post-merge

Git pre-commit hook to prevent commits to master branch

#!/bin/sh

# Check to see if we are on master branch. Stop accidental commits
if [ $(git symbolic-ref HEAD 2>/dev/null) == "refs/heads/master" ]
then
  echo "Cannot commit to master branch"
  exit 1
fi
exit 0
