Application packaging ## Arguments management #### Retrieve arguments in the install script from manifest Arguments are given to the install script from the manifest in it's order. For instance, for Roundcube, `domain` and `path` arguments will respectively be retreived from environment variables or from `$1` and `$2` parameters in the install script. ```bash # Retrieve arguments domain=$YNH_APP_ARG_DOMAIN path=$YNH_APP_ARG_PATH ``` #### Save arguments for other scripts Remove, upgrade, backup and restore scripts could need arguments. YunoHost could save arguments with this command which is generally used in the install script: ```bash # Store config on YunoHost instance ynh_app_setting_set $app domain $domain ``` Then, the script can retrieve saved arguments with this command: ```bash domain=$(ynh_app_setting_get $app domain) ``` Those data are saved in `/etc/yunohost/apps//settings.yml`.
