prepush / git hooks

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

Example script (ask dev to confirm before pushing on wrong branch)

#!/bin/sh
# An example hook script to verify what is about to be pushed.  Called by "git
# push" after it has checked the remote status, but before anything has been
# pushed.  If this script exits with a non-zero status nothing will be pushed.
#
# This hook is called with the following parameters:
#
# $1 -- Name of the remote to which the push is being done
# $2 -- URL to which the push is being done
#
# Information about the commits which are being pushed is supplied as lines to
# the standard input in the form:
#
#   <local ref> <local oid> <remote ref> <remote oid>
#
# This sample shows how to prevent push of commits where the log message starts
# with "WIP" (work in progress).

Evt.

  echo "Allowed branch (f): ${GREEN}${allowed_branch_name}${RESET}"

hvis f er for å checkoute til den branchen:

alias fe="git checkout $(cat ~/assigned-feature-branch.txt)"

Se dotfiles

Insert the current branch into the top of the pre-push file

sed -i "" "s&An example&$(git branch --show-current)\n# An example&" .git/hooks/pre-push

Replace "An example" with current branch \n # An example

Copy current branch to Mac clipboard

echo $(git branch --show-current) | pbcopy

From vim:

:!echo $(git branch --show-current) | pbcopy

Check if a file exists (pre-push example)

Bash

Search replace in pre-push(.sample)

# 1: new branch name
function update_prepush {
  sed -i'' -e "s/allowed_branch_name=\".*\"/allowed_branch_name=\"$1\"/g" $(gitHookFull pre-push)
}
#1: name of git hook (e.g. pre-push, post-commit)
function gitHookFull {
if [[ -f ".git/hooks/$1" ]]; then
echo ".git/hooks/$1"
else
if [[ -f ".git/hooks/$1.sample" ]]; then
echo ".git/hooks/$1.sample"
else
echo "undefined"
fi
fi
}

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
