#ynh_script_progression --message="Adding a configuration file..." --weight=1

### 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_add_config 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_add_config` for more info.

######ynh_add_config --template="some_config_file" --destination="$final_path/some_config_file"

# 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 "$final_path/some_config_file"
#######chown $app:$app "$final_path/some_config_file"

### 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="$final_path/some_config_file"
### ynh_store_file_checksum --file="$final_path/some_config_file"
