#
|
||||
# A new command has a unique combination of:
|
||||
# command name, required option args and required
|
||||
# positional args.
|
||||
#
|
||||
# To define a new command, begin a single line with a
|
||||
# command name, followed by required options/args,
|
||||
# (e.g. --foo, or --foo val), followed by required
|
||||
# positional args, (e.g. VG)
|
||||
#
|
||||
# After the single line of required elements are lines
|
||||
# of optional elements:
|
||||
# . optional options/args are on new line that begins OO:
|
||||
# . optional positional args are on a new line that begins OP:
|
||||
#
|
||||
# command_name required_opt_arg ... required_pos_arg ...
|
||||
# OO: optional_opt_arg, ...
|
||||
# OP: optional_pos_arg ...
|
||||
#
|
||||
# required_opt_arg/optional_opt_arg must begin with the
|
||||
# long form option name, e.g. --foo. If the option name
|
||||
# takes a value, then the type of value is specified,
|
||||
# e.g. --foo String.
|
||||
#
|
||||
# Possible option names are listed in args.h
|
||||
#
|
||||
# Use --foo_long to specify that only the long form of
|
||||
# --foo is accepted by the command. (This is uncommon.)
|
||||
#
|
||||
# Possible option arg types that can follow --opt are:
|
||||
# Bool, Number, String, PV, VG, LV, Tag, Select.
|
||||
#
|
||||
# Option args outside the list of types are treated as literal
|
||||
# (non-variable) strings or numbers.
|
||||
#
|
||||
# required_pos_arg/optional_pos_arg can be one of the following:
|
||||
# PV, VG, LV, Tag, Select.
|
||||
#
|
||||
# required_pos_arg/optional_pos_arg can be multiple types
|
||||
# separated by |, e.g. VG|LV|Tag
|
||||
#
|
||||
# If the required_pos_arg/optional_pos_arg is repeatable,
|
||||
# it is followed by ..., e.g. VG|LV|Tag ...
|
||||
#
|
||||
# LV can have a suffix indicating the LV type, e.g. LV_linear, LV_thinpool.
|
||||
# LV_raid represents any raidN.
|
||||
#
|
||||
# VG, LV can have the suffix _new, indicating the named VG or LV
|
||||
# does not yet exist.
|
||||
#
|
||||
# If Select is included in pos_arg, it means that the pos_arg
|
||||
# may be empty if the --select option is used.
|
||||
#
|
||||
# To define a common set of options:
|
||||
# OO_NAME: --foo, --bar String
|
||||
#
|
||||
# To use this set of options, include it on the OO: line, e.g.
|
||||
# OO: --example, OO_NAME
|
||||
#
|
||||
# which is expaneded to
|
||||
# OO: --example, --foo, --bar String
|
||||
#
|
||||
# Including OO_NAME after a command name on the required line
|
||||
# means that any one of the options is required and the rest
|
||||
# are optional. The usage syntax for this case is printed as:
|
||||
# command (--foo A, --bar B)
|
||||
#
|
||||
|
||||
#
|
||||
# OO_ALL is included in every command automatically.

|
||||
# accept them even if they are not used?
