#!/usr/bin/env bash
#
# Post-clone install script for occweb.
#
# Usage (from nextcloud/apps/):
#   git clone https://github.com/fanategorius/occweb.git
#   bash occweb/install.sh [nextcloud-root] [web-user]
#
# Defaults: nextcloud-root=/var/www/nextcloud, web-user=www-data
#
# What it does:
#   1. Removes dev/CI-only files that aren't needed to run the app
#      (tests, CI config, PHPUnit config, composer files, Makefile).
#   2. chown -R's the app directory to the web server user.
#   3. Enables the app via occ.
#
# Note: this deletes files that are tracked in git. If you plan to keep
# updating this install with `git pull`, be aware that a future upstream
# change to one of the removed files could make a plain `git pull` refuse
# to merge (it will tell you so, and you can `git checkout -- <file>` to
# recover it, or re-clone instead of pulling).
