# Internal helper design to allow helpers to use getopts to manage their arguments
|
||||
#
|
||||
# example: function my_helper()
|
||||
# {
|
||||
# declare -Ar 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:
|
||||
# declare -Ar 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
|
||||
# declare -Ar 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.
