-# Create a dedicated config file from a jinja template
-#
-# usage: ynh_add_jinja_config --template="template" --destination="destination"
-# | arg: -t, --template=     - Template config file to use
-# | arg: -d, --destination=  - Destination of the config file
-# | arg: -i, --ignore_vars=  - List separated by space of script variables to ignore and don't pass in the jinja context.
-# |                            This could be useful mainly for special share which can't be retried by reference name (like the array).
-#
-# examples:
-#    ynh_add_jinja_config --template="app.conf" --destination="$install_dir/app.conf"
-#    ynh_add_jinja_config --template="app-env" --destination="$install_dir/app-env" --ignore_vars="complex_array yolo"
-#
-# The template can be by default the name of a file in the conf directory
-#
-# The helper will verify the checksum and backup the destination file
-# if it's different before applying the new template.
-#
-# And it will calculate and store the destination file checksum
-# into the app settings when configuration is done.
-#
-##
-## About the variables passed to the template:
-##
-#
-# All variable defined in the script are available into the template (as string) except someone described below.
-# If a variable make crash the helper for some reason (by example if the variable is of type array)
-# or you just want to don't pass a specific variable for some other reason you can add it in the '--ignore_vars=' parameter as described above.
-# Here are the list of ignored variable and so there won't never be available in the template:
-# - All system environment variable like (TERM, USER, PATH, LANG, etc).
-#   If you need someone you just need to declare an other variable with the same value.
-#   Note that all Yunohost variable whose name begins by 'YNH_' are available and can be used in the template.
-# - This following list:
-#        legacy_args args_array template destination ignore_vars template_path python_env_var ignore_var_regex
-#        progress_scale progress_string0 progress_string1 progress_string2
-#        old changed binds types file_hash formats
-#
-##
-## Usage in templates:
-##
-#
-# For a full documentation of the template you can refer to: https://jinja.palletsprojects.com/en/3.1.x/templates/
-# In Yunohost context there are no really some specificity except that all variable passed are of type string.
-# So here are some example of recommended usage:
-#
-# If you need a conditional block
-#
-# {% if should_my_block_be_shown == 'true' %}
-# ...
-# {% endif %}
-#
-# or
-#
-# {% if should_my_block_be_shown == '1' %}
-# ...
-# {% endif %}
-#
-# If you need to iterate with loop:
-#
-# {% for yolo in var_with_multiline_value.splitlines() %}
-# ...
-# {% endfor %}
-#
-# or
-#
-# {% for jail in my_var_with_coma.split(',') %}
-# ...
-# {% endfor %}
