@ -48,6 +48,23 @@ Friendica uses [Composer](https://getcomposer.org) to manage dependencies librar
It's a command-line tool that downloads required libraries into the `vendor` folder and makes any namespaced class in `src` available through the whole application through `boot.php`.
If you want to have git automatically update the dependencies with composer, you can use the `post-merge` [git-hook](https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks) with a script similar to this one:
#/usr/bin/env bash
# MIT © Sindre Sorhus - sindresorhus.com
# forked by Gianluca Guarini
# phponly by Ivo Bathke ;)
# modified for Friendica by Tobias Diekershoff
changed_files="$(git diff-tree -r --name-only --no-commit-id ORIG_HEAD HEAD)"
check_run() {
echo "$changed_files" | grep --quiet "$1" && eval "$2"
}
# `composer install` if the `composer.lock` file gets changed
# to update all the php dependencies
check_run composer.lock "util/composer.phar install --no-dev"
just place it into `.git/hooks/post-merge` and make it executeable.
