How effectively delete a git submodule.

To remove a submodule you need to:

  • Delete the relevant section from the .gitmodules file.
  • Stage the .gitmodules changes git add .gitmodules
  • Delete the relevant section from .git/config.
  • Run git rm --cached path_to_submodule (no trailing slash).
  • Run rm -rf .git/modules/path_to_submodule (no trailing slash).
  • Commit git commit -m "Removed submodule "
  • Delete the now untracked submodule files rm -rf path_to_submodule

Steps to enable GPG signing of git commits.

If anyone is interested in setting up their system to automatically (or manually) sign their git commits with their GPG key, here are the steps:

  1. Generate and add your key to GitHub
  2. $ git config --global commit.gpgsign true ([OPTIONAL] every commit will now be signed)
  3. $ git config --global user.signingkey ABCDEF01 (where ABCDEF01 is the fingerprint of the key to use)
  4. $ git config --global alias.logs "log --show-signature" (now available as $ git logs)
  5. $ git config --global alias.cis "commit -S" (optional if global signing is false)
  6. $ echo "Some content" >> example.txt
  7. $ git add example.txt
  8. $ git cis -m "This commit is signed by a GPG key." (regular commit will work if global signing is enabled)

Email address syntax validation? Let the browser do it (without regexp)

Here is a simple and robust way to check for the validity of an email address syntax directly in the browser. No need for crazy regular expressions.

e = document.createElement('input')
e.type = 'email'
// check some email addresses
e.value = 'hi@'

Where to find changes due to git fetch — First published in fullweb.io issue #78

Where to find changes due to git fetch

fetch is useful to pull changes from an upstream repo to merge some changes. By default git fetch upstream will update or create all the remote branches locally.

Say you have upstream/master tracked by your local master branch. Here is how to see the changes between both:

git log master..upstream/master

Recursive Laravel Collection Macros

What?

If a nested array is passed into a Laravel Collection, by default these will be threaded as normal arrays.

However, that's not always the ideal case and it would be nice if we could have nested collections in a cleaner way.

This is where this macro comes in handy.
