### About --time --weight and --time
### ynh_script_progression will show to your final users the progression of each scripts.
### In order to do that, --time --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=2

### If the app uses nginx as web server (written in HTML/PHP in most cases), the final path should be "/var/www/$app".

#=================================================
# SETUP SYSTEMD
#=================================================
ynh_script_progression --message="Configuring a systemd service..." --time --weight=2

### `ynh_systemd_config` is used to configure a systemd script for an app.
### It can be used for apps that use sysvinit (with adaptation) or systemd.
### Have a look at the app to be sure this app needs a systemd script.
### `ynh_systemd_config` will use the file conf/systemd.service
### If you're not using these lines:
###		- You can remove those files in conf/.
###		- Remove the section "BACKUP SYSTEMD" in the backup script
###		- Remove also the section "STOP AND REMOVE SERVICE" in the remove script
###		- As well as the section "RESTORE SYSTEMD" in the restore script
###		- And the section "SETUP SYSTEMD" in the upgrade script

# Create a dedicated systemd config
#ynh_add_systemd_config

ynh_add_systemd_config --service="$app" --template="systemd.service"

#=================================================
# 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_script_progression --message="Securing files and directories..." --time --weight=1
### For security reason, any app should set the permissions to root: before anything else.

#=================================================
# SETUP LOGROTATE
#=================================================
ynh_script_progression --message="Configuring log rotation..." --time --weight=2

### `ynh_use_logrotate` is used to configure a logrotate configuration for the logs of this app.
### Use this helper only if there is effectively a log file for this app.
### If you're not using this helper:
###		- Remove the section "BACKUP LOGROTATE" in the backup script
###		- Remove also the section "REMOVE LOGROTATE CONFIGURATION" in the remove script
###		- As well as the section "RESTORE THE LOGROTATE CONFIGURATION" in the restore script
###		- And the section "SETUP LOGROTATE" in the upgrade script

#=================================================
# INTEGRATE SERVICE IN YUNOHOST
#=================================================

### `yunohost service add` integrates a service in YunoHost. It then gets 
### displayed in the admin interface and through the others `yunohost service` commands.
### (N.B. : this line only makes sense if the app adds a service to the system!)
### If you're not using these lines:
###		- You can remove these files in conf/.
###		- Remove the section "REMOVE SERVICE FROM ADMIN PANEL" in the remove script
###		- As well as the section "ADVERTISE SERVICE IN ADMIN PANEL" in the restore script

yunohost service add $app --description "Standard Notes - Syncing Server" 

### With YunoHost 3.8 you will then be able to: 
### - specify a list of ports that needs to be publicly exposed (c.f. --needs_exposed_ports) 
###   which will then be checked by YunoHost's diagnosis system
### - specify a custom command to check the status of the service (c.f. --test_status)
###   though it's only needed for weird cases where 'systemctl status' doesn't do a good job
### - specify a custom command to check / validate the configuration of the service (c.f. --test_conf)
###   for example, the command to check the configuration of nginx is "nginx -t"

ynh_script_progression --message="Starting a systemd service..." --time --weight=1

### If you're not using these lines:
###		- Remove the section "STOP SYSTEMD SERVICE" and "START SYSTEMD SERVICE" in the backup script
###		- As well as the section "START SYSTEMD SERVICE" in the restore script
###		- As well as the section"STOP SYSTEMD SERVICE" and "START SYSTEMD SERVICE" in the upgrade script
