flohmarkt_ynh/scripts/_common.sh
Chris Vogel 047af9605c new versions of ynh_local_curl and ynh_handle_getopts_args 
included in _common.sh as

* flohmarkt_ynh_handle_getopts_args and
* flohmarkt_ynh_local_curl

to be tested.

Added some simple debugging sub to easily switch on and off my debugging output.

# Redisgn of ynh_handle_getopts_args for flohmarkt to be tested as `flohmarkt_ynh_handle_getopts_args`
# 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.
#
# To keep a retrocompatibility, a package can still call a helper, using getopts, with positional arguments.
# The "legacy mode" will manage the positional arguments and fill the variable in the same order than they are given
# in $args_array. e.g. for `my_helper "val1" val2`, arg1 will be filled with val1, and arg2 with val2.
# Positional parameters (used to be the only way to use ynh_handle_getopts_args once upon a time) can be
# used also:
#
# '--' start processing the rest of the arguments as positional parameters
# $legacy_args The arguments positional parameters will be assign to
# Needs to be composed of array keys of args_array. If a key for a predefined variable
# is used multiple times the assigned values will be concatenated delimited by ';'.
# If the long option variable to contain the data is predefined as an array (e.g. using
# `local -a arg1` then multiple values will be assigned to its cells.
# If the last positional parameter defined in legacy_args is defined as an array all
# the leftover positional parameters will be assigned to its cells.
# (it is named legacy_args, because the use of positional parameters was about to be
# deprecated before the last re-design of this sub)
#
# Requires YunoHost version 3.2.2 or higher.
