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

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

git reset soft | remove last commit and move code to working dir

git reset --soft HEAD~1

Fzf lua

Q for selecting all elements with fzf-lua:

config.defaults.keymap.fzf["ctrl-q"] = "select-all+accept"

From Lazyvim config: https://github.com/LazyVim/LazyVim/blob/main/lua/lazyvim/plugins/extras/editor/fzf.lua

Fzf use cases

Edit a file

nvim $(fzf)

Restore a file from another branch (here: main)

git checkout main $(fzf)

Run a specific test in Jest

npx jest --runTestsByPath $(fzf)

Jump to main component vim

Vim/Neovim

yank filename without extension to 'f'-registry

:let @f = expand('%:t:r')<CR>

search for "const [contents in 'f'-registry]"

:execute '/const ' . @f<CR>:nohlsearch<CR>

added together

:let @f = expand('%:t:r')<CR>:execute '/const ' . @f<CR>:nohlsearch<CR>

Ideavim

Copy file name to + register and search for it. Do not execute immediately () as CopyFileName also includes the file extension

:action CopyFileName<CR>/const <c-r>+
