# Internal helper design to allow helpers to use getopts to manage their arguments
#
# [internal]
#
# example: function my_helper()
# {
# local -A args_array=( [a]=arg1= [b]=arg2= [c]=arg3 )
# local arg1
# local arg2
# local arg3
# ynh_handle_getopts_args "$@"
#
# [...]
# }
# my_helper --arg1 "val1" -b val2 -c
#
# usage: ynh_handle_getopts_args "$@"
# | arg: $@ - Simply "$@" to tranfert all the positionnal arguments to the function
#
# This helper need an array, named "args_array" with all the arguments used by the helper
# that want to use ynh_handle_getopts_args
# Be carreful, this array has to be an associative array, as the following example:
# local -A args_array=( [a]=arg1 [b]=arg2= [c]=arg3 )
# Let's explain this array:
# a, b and c are short options, -a, -b and -c
# arg1, arg2 and arg3 are the long options associated to the previous short ones. --arg1, --arg2 and --arg3
# For each option, a short and long version has to be defined.
# Let's see something more significant
# local -A args_array=( [u]=user [f]=finalpath= [d]=database )
#
# NB: Because we're using 'declare' without -g, the array will be declared as a local variable.
#
# Please keep in mind that the long option will be used as a variable to store the values for this option.
# For the previous example, that means that $finalpath will be fill with the value given as argument for this option.
#
# Also, in the previous example, finalpath has a '=' at the end. That means this option need a value.
# So, the helper has to be call with --finalpath /final/path, --finalpath=/final/path or -f /final/path, the variable $finalpath will get the value /final/path
# If there's many values for an option, -f /final /path, the value will be separated by a ';' $finalpath=/final;/path
# For an option without value, like --user in the example, the helper can be called only with --user or -u. $user will then get the value 1.

#
# This example will create a new permission permission with this following effect:
# - A tile named "My app admin" in the SSO will be available for the users alice and bob. This tile will point to the relative url '/admin'.
# - Only the user alice and bob will have the access to theses following url: /admin, domain.tld/admin, /superadmin
#

# Example 2:
#
# ynh_permission_create --permission=api --url=domain.tld/api --auth_header=false --allowed=visitors \
# --protected=true
#
# This example will create a new protected permission. So the admin won't be able to add/remove the visitors group of this permission.
# In case of an API with need to be always public it avoid that the admin break anything.
# With this permission all client will be allowed to access to the url 'domain.tld/api'.
# Note that in this case no tile will be show on the SSO.
# Note that the auth_header parameter is to 'false'. So no authentication header will be passed to the application.
# Generally the API is requested by an application and enabling the auth_header has no advantage and could bring some issues in some case.

#

# / -> domain.tld/app
# /admin -> domain.tld/app/admin
# domain.tld/app/api -> domain.tld/app/api
#
# 'url' or 'additional_urls' can be treated as a PCRE (not lua) regex if it starts with "re:".
# For example:
# re:/api/[A-Z]*$ -> domain.tld/app/api/[A-Z]*$
# re:domain.tld/app/api/[A-Z]*$ -> domain.tld/app/api/[A-Z]*$
#
# Note that globally the parameter 'url' and 'additional_urls' are same. The only difference is:
# - 'url' is only one url, 'additional_urls' can be a list of urls. There are no limitation of 'additional_urls'
# - 'url' is used for the url of tile in the SSO (if enabled with the 'show_tile' parameter)

# - `$php_process_management`: corresponds to "pm" (ondemand, dynamic, static). Defaults to ondemand
# - `$php_max_children`: by default, computed from "total RAM" divided by 40, cf `_default_php_max_children`
# - `$php_memory_limit`: by default, 128M (from global php.ini)

# | arg: --dest_dir= - Directory where to setup sources

# | arg: --keep= - Space-separated list of files/folders that will be backup/restored in $dest_dir, such as a config file you don't want to overwrite. For example 'conf.json secrets.json logs' (no trailing `/` for folders)

# sha256 = "0123456789abcdef" # The sha256 sum of the asset obtained from the URL
# ```
#
# (See also the resources documentation which may be more complete?)
#
# ##### Optional flags in the 'sources' resource
#
# ```text
# format = "tar.gz"/xz/bz2/tar # automatically guessed from the extension of the URL, but can be set explicitly. Will use `tar` to extract
# "zip" # automatically guessed from the extension of the URL, but can be set explicitly. Will use `unzip` to extract
# "docker" # useful to extract files from an already-built docker image (instead of rebuilding them locally). Will use `docker-image-extract` to extract
# "whatever" # an arbitrary value, not really meaningful except to imply that the file won't be extracted
#
# in_subdir = true # default, there's an intermediate subdir in the archive before accessing the actual files
# false # sources are directly in the archive root
# n # (special cases) an integer representing a number of subdirs levels to get rid of
#
# extract = true # default if file is indeed an archive such as .zip, .tar.gz, .tar.bz2, ...
# = false # default if file 'format' is not set and the file is not to be extracted because it is not an archive but a script or binary or whatever asset.
# # in which case the file will only be `mv`ed to the location possibly renamed using the `rename` value
#
# rename = "whatever_your_want" # to be used for convenience when `extract` is false and the default name of the file is not practical (the default filename being the value of `source_id` arg and not the upstream basename).
# platform = "linux/amd64" # (defaults to "linux/$YNH_ARCH") to be used in conjonction with `format = "docker"` to specify which architecture to extract for
# ```
#
# You may also define assets url and checksum per-architectures such as:
#
# ```toml
# [resources.sources]
# [resources.sources.main]
# amd64.url = "https://some.address.to/download/the/app/archive/when/amd64"
# amd64.sha256 = "0123456789abcdef"
# armhf.url = "https://some.address.to/download/the/app/archive/when/armhf"

# ```
#

#
# The helper will:
#
# - Download the specific URL if there is no local archive
# - Check the integrity with the specific sha256 sum
# - Uncompress the archive to `$dest_dir`.
# - If `in_subdir` is true, the first level directory of the archive will be removed.
# - If `in_subdir` is a numeric value, the N first level directories will be removed.
# - Patches named `patches/${src_id}/*.patch` will be applied to `$dest_dir`

# Create a dedicated config file from a template
#
# usage: ynh_config_add --template="template" --destination="destination"
# | arg: --template= - Template config file to use
# | arg: --destination= - Destination of the config file
# | arg: --jinja - Use jinja template instead of the simple `__MY_VAR__` templating format
#
# examples:
# ynh_config_add --template=".env" --destination="$install_dir/.env" # (use the template file "conf/.env" from the app's package)
# ynh_config_add --jinja --template="config.j2" --destination="$install_dir/config" # (use the template file "conf/config.j2" from the app's package)
#
# The template can be 1) the name of a file in the `conf` directory of
# the app, 2) a relative path or 3) an absolute path.
#
# This applies a simple templating format which covers a good 95% of cases,
# where patterns like `__FOO__` are replaced by the bash variable `$foo`, for example:
# `__DOMAIN__` by `$domain`
# `__PATH__` by `$path`
# `__APP__` by `$app`
# `__VAR_1__` by `$var_1`
# `__VAR_2__` by `$var_2`
#
# For this to work, template tags must be in uppercase and variables names must be in lowercase (for instance `__MY_var__` or `$myVar` would not be replaced as expected).
#
# Special case for `__PATH__/` which is replaced by `/` instead of `//` if `$path` is `/`
#
# ##### When --jinja is enabled
#
# This option is meant for advanced use-cases where the "simple" templating
# mode ain't enough because you need conditional blocks or loops.
#
# For a full documentation of jinja's syntax you can refer to [the official Jinja documentation](https://jinja.palletsprojects.com/en/3.1.x/templates/).
#
# Note that in YunoHost context, all variables are from shell variables and therefore are strings
# To help handling complex data Jinja engine are executed with theses additional filters:
# - from_json: load a string as Json and return an object
# - from_yaml: load a string as Yaml and return an object
# - from_toml: load a string as Toml and return an object
# - to_json: serialize to string an object to Json
# - to_yaml: serialize to string an object to Yaml
# - to_toml: serialize to string an object to Toml
#
# So by example, if you want to convert a json string `$my_json` to Toml, you can to this way:
# `{{ my_json | from_json | to_toml }}`
# Or you can iterate on a Json list `my_list='["a", "b", "c"]'` this way:
# ```
# {% for i in my_list | from_json %}
# value {{ i }}
# {% endfor }}
# ```
#
# which will result:
# ```
# value a
# value b
# value c
# ```
#
# ##### Keeping track of manual changes by the admin
#
# 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.
