### If it's a multi-instance app, meaning it can be installed several times independently
### The id of the app as stated in the manifest is available as $YNH_APP_ID
### The instance number is available as $YNH_APP_INSTANCE_NUMBER (equals "1", "2", ...)
### The app instance name is available as $YNH_APP_INSTANCE_NAME
###    - the first time the app is installed, YNH_APP_INSTANCE_NAME = ynhexample
###    - the second time the app is installed, YNH_APP_INSTANCE_NAME = ynhexample__2
###    - ynhexample__{N} for the subsequent installations, with N=3,4, ...
### The app instance name is probably what interests you most, since this is
### guaranteed to be unique. This is a good unique identifier to define installation path,
### db names, ...

#=================================================
# CHECK IF THE APP CAN BE INSTALLED WITH THESE ARGS
#=================================================

### If the app uses nginx as web server (written in HTML/PHP in most cases), the final path should be "/var/www/$app".
### If the app provides an internal web server (or uses another application server such as uwsgi), the final path should be "/opt/yunohost/$app"
final_path=/var/www/$app
test ! -e "$final_path" || ynh_die "This path already contains a folder"

# STANDARD MODIFICATIONS
#=================================================
# INSTALL DEPENDENCIES
#=================================================

### `ynh_install_app_dependencies` allows you to add any "apt" dependencies to the package.
### Those deb packages will be installed as dependencies of this package.
### If you're not using this helper:
###		- Remove the section "REMOVE DEPENDENCIES" in the remove script
###		- As well as the section "REINSTALL DEPENDENCIES" in the restore script
###		- And the section "UPGRADE DEPENDENCIES" in the upgrade script

ynh_install_app_dependencies php7.0-curl php7.0-gd php7.0-cli php7.0-mysql php-xml php7.0-mbstring


#=================================================
# CREATE A MYSQL DATABASE
#=================================================

### Use these lines if you need a database for the application.
### `ynh_mysql_setup_db` will create a database, an associated user and a ramdom password.
### The password will be stored as 'mysqlpwd' into the app settings,
### and will be available as $db_pwd
### If you're not using these lines:
###		- Remove the section "BACKUP THE MYSQL DATABASE" in the backup script
###		- Remove also the section "REMOVE THE MYSQL DATABASE" in the remove script
###		- As well as the section "RESTORE THE MYSQL DATABASE" in the restore script

db_name=$(ynh_sanitize_dbid $app)
ynh_app_setting_set $app db_name $db_name
ynh_mysql_setup_db $db_name $db_name

#=================================================
# DOWNLOAD, CHECK AND UNPACK SOURCE
#=================================================

### `ynh_setup_source` is used to install an app from a zip or tar.gz file,
### downloaded from an upstream source, like a git repository.
### `ynh_setup_source` use the file conf/app.src

ynh_app_setting_set $app final_path $final_path
# Download, check integrity, uncompress and patch the source from app.src
ynh_setup_source "$final_path"

#=================================================
# NGINX CONFIGURATION
#=================================================

### `ynh_add_nginx_config` will use the file conf/nginx.conf

# Create a dedicated nginx config
ynh_add_nginx_config

#=================================================
# CREATE DEDICATED USER
#=================================================

# Create a system user
ynh_system_user_create $app

#=================================================
# PHP-FPM CONFIGURATION
#=================================================

### `ynh_add_fpm_config` is used to set up a PHP config.
### You can remove it if your app doesn't use PHP.
### `ynh_add_fpm_config` will use the files conf/php-fpm.conf and conf/php-fpm.ini
### If you're not using these lines:
###		- You can remove these files in conf/.
###		- Remove the section "BACKUP THE PHP-FPM CONFIGURATION" in the backup script
###		- Remove also the section "REMOVE PHP-FPM CONFIGURATION" in the remove script
###		- As well as the section "RESTORE THE PHP-FPM CONFIGURATION" in the restore script
###		With the reload at the end of the script.
###		- And the section "PHP-FPM CONFIGURATION" in the upgrade script

# Create a dedicated php-fpm config
ynh_add_fpm_config

#=================================================
# MODIFY A CONFIG FILE (TO DO: Automate install)
#=================================================

### `ynh_replace_string` is used to replace a string in a file.
### (It's compatible with sed regular expressions syntax)
## cp -f ../conf/config.ini.php "$final_path/config/config.ini.php"
## ynh_replace_string "__DB__"          "$db_name" "$final_path/config/config.ini.php"
## ynh_replace_string "__DB_PASSWORD__" "$db_pwd"  "$final_path/config/config.ini.php"


#=================================================
# GENERIC FINALIZATION
#=================================================

# Set permissions to app files
chown -R $app: $final_path

# Set up cron
ynh_replace_string  "YNH_WWW_PATH" "$final_path" ../conf/cron
ynh_replace_string "__USER__" "$app"  ../conf/cron
ynh_replace_string "__DOMAIN__" "$domain"  ../conf/cron
ynh_replace_string "__PATH__" "$path_url"  ../conf/cron
sudo cp -f ../conf/cron /etc/cron.d/$app


#=================================================
# SETUP SSOWAT
#=================================================

# Make app public if necessary
if [ $is_public -eq 1 ]
then
	# unprotected_uris allows SSO credentials to be passed anyway.
	ynh_app_setting_set $app unprotected_uris "/"
