# STANDARD MODIFICATIONS
#=================================================
# FIND AND OPEN A PORT
#=================================================
### Use these lines if you have to open a port for the application
### `ynh_find_port` will find the first available port starting from the given port.
### If you're not using these lines:
### - Remove the section "CLOSE A PORT" in the remove script
# Find a free port
port=$(ynh_find_port 3128)
# Open this port
yunohost firewall allow --no-upnp TCP $port 2>&1
ynh_app_setting_set $app port $port
#=================================================
# INSTALL DEPENDENCIES
#=================================================
### `ynh_install_app_dependencies` allows you to add any "apt" dependencies to the package.
### Those deb packages will be installed as dependencies of this package.
### If you're not using this helper:
### - Remove the section "REMOVE DEPENDENCIES" in the remove script
### - As well as the section "REINSTALL DEPENDENCIES" in the restore script
### - And the section "UPGRADE DEPENDENCIES" in the upgrade script
ynh_install_app_dependencies squid3
#=================================================
# MODIFY A CONFIG FILE
#=================================================
### `ynh_replace_string` is used to replace a string in a file.
### (It's compatible with sed regular expressions syntax)
ynh_replace_string "__ADMIN_PASS__" "$admin_pass_yuno" "../conf/squid.conf"
ynh_replace_string "__PORT__" "$port" "../conf/squid.conf"

#=================================================
# 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

#=================================================
# ADVERTISE SERVICE IN ADMIN PANEL
#=================================================
### `yunohost service add` is a CLI yunohost command to add a service in the admin panel.
### You'll find the service in the 'services' section of YunoHost admin panel.
### This CLI command would be useless if the app does not have any services (systemd or sysvinit)
### 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 squid --log "/var/log/squid/access.log"
