### App file generated with YoloGen, the Yunohost app generator, version .

# This is the tutorial version of the app.
# It contains extra commands to explain what should be done in case you want to adjust some part of the script.
# Once you are done, you may remove them.

### Install parameters are automatically saved as settings
###
### Settings are automatically loaded as bash variables
### in every app script context, therefore typically these will exist:
### - $domain
### - $path
### - $language
### ... etc
###
### Resources defined in the manifest are provisioned prior to this script
### and corresponding settings are also available, such as:
### - $install_dir
### - $port
### - $db_name
### ...
###
### $app is the app id (i.e. 'example' for first install,
### or 'example__2', '__3'... for multi-instance installs)

# DOWNLOAD, CHECK AND UNPACK SOURCE
#=================================================
ynh_script_progression "Setting up source files..."

### `ynh_setup_source` is used to install an app from a zip or tar.gz file,
### downloaded from an upstream source, as defined in the manifest.toml

ynh_setup_source --dest_dir="$install_dir"

# $install_dir will automatically be initialized with some decent
# permission by default ... however, you may need to recursively reapply
# ownership to all files such as after the ynh_setup_source step

chown -R $app:www-data "$install_dir"

#=================================================
# ADD A CONFIGURATION
#=================================================
ynh_script_progression "Adding app's configuration file..."

### You can add specific configuration files.
###
### Typically, put your template conf file in ../conf/your_config_file
### The template may contain strings such as __FOO__ or __FOO_BAR__,
### which will automatically be replaced by the values of $foo and $foo_bar
###
### ynh_config_add will also keep track of the config file's checksum,
### which later during upgrade may allow to automatically backup the config file
### if it's found that the file was manually modified
###
### Check the documentation of `ynh_config_add` for more info.

ynh_config_add --template="" --destination="$install_dir/"

# FIXME: this should be handled by the core in the future
### You may need to use chmod 600 instead of 400,
### for example if the app is expected to be able to modify its own config

chmod 400 "$install_dir/"
chown "$app:$app" "$install_dir/"

### For more complex cases where you want to replace stuff using regexes,
### you shoud rely on ynh_replace_string (which is basically a wrapper for sed)
### When doing so, you also need to manually call ynh_store_file_checksum
###
### ynh_replace_string --match_string="match_string" --replace_string="replace_string" --target_file="$install_dir/"
### ynh_store_file_checksum --file="$install_dir/"

# SYSTEM CONFIGURATION

# Create a dedicated NGINX config using the conf/nginx.conf template

### `ynh_config_add_systemd` 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_config_add_systemd` will use the file conf/systemd.service

ynh_config_add_systemd

### `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!)

### Additional options starting with 3.8:
###
### --needs_exposed_ports "$port" a list of ports that needs to be publicly exposed
###                               which will then be checked by YunoHost's diagnosis system
###                               (N.B. DO NOT USE THIS if the port is only internal!!!)
###
### --test_status "some command"  a custom command to check the status of the service
###                               (only relevant if 'systemctl status' doesn't do a good job)
###
### --test_conf "some command"    some command similar to "nginx -t" that validates the conf of the service
###
### Re-calling 'yunohost service add' during the upgrade script is the right way
### to proceed if you later realize that you need to enable some flags that
### weren't enabled on old installs (be careful it'll override the existing
### service though so you should re-provide all relevant flags when doing so)

yunohost service add "$app" --description="A short description of the app" --log="/var/log/$app/$app.log"

# FINALIZE APP INSTALL WITH CURL
#=================================================
ynh_script_progression "Finalizing installation..."

### Use these lines only if the app installation needs to be finalized through
### web forms. We generally don't want to ask the final user,
### so we're going to use curl to automatically fill the fields and submit the
### forms.

ynh_local_curl "/INSTALL_PATH" "key1=value1" "key2=value2" "key3=value3"

#=================================================
# START SYSTEMD SERVICE
#=================================================
ynh_script_progression "Starting app's systemd service..."

### `ynh_systemctl` is used to start a systemd service for an app.
### Only needed if you have configure a systemd service
### 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
###   - And the section "STOP SYSTEMD SERVICE" and "START SYSTEMD SERVICE" in the change_url script
