### 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, ...

### About --weight and --time
### ynh_script_progression will show to your final users the progression of each scripts.
### In order to do that, --weight will represent the relative time of execution compared to the other steps in the script.
### --time is a packager option, it will show you the execution time since the previous call.
### This option should be removed before releasing your app.
### Use the execution time, given by --time, to estimate the weight of a step.
### A common way to do it is to set a weight equal to the execution time in second +1.
### The execution time is given for the duration since the previous call. So the weight should be applied to this previous call.
ynh_script_progression --message="Validating installation parameters..." --time --weight=1

### 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

# INSTALL DEPENDENCIES
#=================================================
ynh_script_progression --message="Installing dependencies..." --time --weight=1

### `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
###		- Remove the variable "pkg_dependencies" in _common.sh
###		- As well as the section "REINSTALL DEPENDENCIES" in the restore script
###		- And the section "UPGRADE DEPENDENCIES" in the upgrade script

# CREATE A MYSQL DATABASE

ynh_script_progression --message="Creating a MySQL database..." --time --weight=1

### 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

ynh_script_progression --message="Setting up source files..." --time --weight=1

### `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_script_progression --message="Configuring php-fpm..." --time --weight=1

### `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
### 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

#=================================================
# STORE THE CONFIG FILE CHECKSUM

### `ynh_store_file_checksum` is used to store the checksum of a file.
### That way, during the upgrade script, by using `ynh_backup_if_checksum_is_different`,
### you can make a backup of this file before modifying it again if the admin had modified it.

# Calculate and store the config file checksum into the app settings
ynh_store_file_checksum --file="$final_path/config/local.config.php"
