prepush / git hooks

To activate pre-push, rename .git/hooks/pre-push.sample to .git/hooks/pre-push

Example script:

GREEN='\033[0;32m'
RED='\033[1;91m'
RESET='\033[0m'
branch_name="$(git branch --show-current)"
allowed_branch_name="my-branch"
if [ "$branch_name" != "$allowed_branch_name" ]; then
echo "Current branch: ${RED}${branch_name}${RESET}"
echo "Allowed branch: ${GREEN}${allowed_branch_name}${RESET}"
echo
echo "You can't push directly to this branch."
exit 1
fi

Check if a file exists (pre-push example)

Bash

Check existence

lpo() {
  if [[ -f ".git/hooks/pre-push" ]]; then
    echo ".git/hooks/pre-push was found:"
    echo "pre-push is activated"
  else
    if [[ -f ".git/hooks/pre-push.sample" ]]; then
      echo ".git/hooks/pre-push was not found:"
      echo "but .git/hooks/pre-push.sample was found:"
      echo "pre-push is deactivated"
    else
      echo "Hmmmmm"
    fi
  fi
}

Nvim edit file

po() {
  if [[ -f ".git/hooks/pre-push" ]]; then
    echo ".git/hooks/pre-push was found:"
    nvim .git/hooks/pre-push
  else
    if [[ -f ".git/hooks/pre-push.sample" ]]; then
      echo ".git/hooks/pre-push was not found:"
      echo "but .git/hooks/pre-push.sample was found:"
      nvim .git/hooks/pre-push.sample
    else
      echo "Hmmmmm"
    fi
  fi
}

Lua nvim edit file

function file_exists(name)
   local f=io.open(name,"r")
   if f~=nil then io.close(f) return true else return false end
end
function open_prepush()
if file_exists(".git/hooks/pre-push") then
vim.cmd("vsplit .git/hooks/pre-push")
elseif file_exists(".git/hooks/pre-push.sample") then
vim.cmd("vsplit .git/hooks/pre-push.sample")
else
vim.cmd("echo 'Hmmmmm'")
end
end
vim.keymap.set("n", "<leader><leader>po", open_prepush, { desc = "Open pre-push a new split" })
