- *
- * cmdname
- * =======
- *
- * Name of the struct that will be defined for the command.
- *
- * cmdstr
- * ======
- *
- * The cmdstr defines the command syntax. It is used by the vty subsystem
- * and vtysh to perform matching and completion in the cli. So you have to take
- * care to construct it adhering to the following grammar. The names used
- * for the production rules losely represent the names used in lib/command.c
- *
- * cmdstr = cmd_token , { " " , cmd_token } ;
- *
- * cmd_token = cmd_terminal
- * | cmd_multiple
- * | cmd_keyword ;
- *
- * cmd_terminal_fixed = fixed_string
- * | variable
- * | range
- * | ipv4
- * | ipv4_prefix
- * | ipv6
- * | ipv6_prefix ;
- *
- * cmd_terminal = cmd_terminal_fixed
- * | option
- * | vararg ;
- *
- * multiple_part = cmd_terminal_fixed ;
- * cmd_multiple = "(" , multiple_part , ( "|" | { "|" , multiple_part } ) , ")" ;
- *
- * keyword_part = fixed_string , { " " , ( cmd_terminal_fixed | cmd_multiple ) } ;
- * cmd_keyword = "{" , keyword_part , { "|" , keyword_part } , "}" ;
- *
- * lowercase = "a" | ... | "z" ;
- * uppercase = "A" | ... | "Z" ;
- * digit = "0" | ... | "9" ;
- * number = digit , { digit } ;
- *
- * fixed_string = (lowercase | digit) , { lowercase | digit | uppercase | "-" | "_" } ;
- * variable = uppercase , { uppercase | "_" } ;
- * range = "<" , number , "-" , number , ">" ;
- * ipv4 = "A.B.C.D" ;
- * ipv4_prefix = "A.B.C.D/M" ;
- * ipv6 = "X:X::X:X" ;
- * ipv6_prefix = "X:X::X:X/M" ;
- * option = "[" , variable , "]" ;
- * vararg = "." , variable ;
- *
- * To put that all in a textual description: A cmdstr is a sequence of tokens,
- * separated by spaces.
- *
- * Terminal Tokens:
- *
- * A very simple cmdstring would be something like: "show ip bgp". It consists
- * of three Terminal Tokens, each containing a fixed string. When this command
- * is called, no arguments will be passed down to the function implementing it,
- * as it only consists of fixed strings.
- *
- * Apart from fixed strings, Terminal Tokens can also contain variables:
- * An example would be "show ip bgp A.B.C.D". This command expects an IPv4
- * as argument. As this is a variable, the IP address entered by the user will
- * be passed down as an argument. Apart from two exceptions, the other options
- * for Terminal Tokens behave exactly as we just discussed and only make a
- * difference for the CLI. The two exceptions will be discussed in the next
- * paragraphs.
- *
- * A Terminal Token can contain a so called option match. This is a simple
- * string variable that the user may omit. An example would be:
- * "show interface [IFNAME]". If the user calls this without an interface as
- * argument, no arguments will be passed down to the function implementing
- * this command. Otherwise, the interface name will be provided to the function
- * as a regular argument.
-
- * Also, a Terminal Token can contain a so called vararg. This is used e.g. in
- * "show ip bgp regexp .LINE". The last token is a vararg match and will
- * consume all the arguments the user inputs on the command line and append
- * those to the list of arguments passed down to the function implementing this
- * command. (Therefore, it doesn't make much sense to have any tokens after a
- * vararg because the vararg will already consume all the words the user entered
- * in the CLI)
- *
- * Multiple Tokens:
- *
- * The Multiple Token type can be used if there are multiple possibilities what
- * arguments may be used for a command, but it should map to the same function
- * nonetheless. An example would be "ip route A.B.C.D/M (reject|blackhole)"
- * In that case both "reject" and "blackhole" would be acceptable as last
- * arguments. The words matched by Multiple Tokens are always added to the
- * argument list, even if they are matched by fixed strings. Such a Multiple
- * Token can contain almost any type of token that would also be acceptable
- * for a Terminal Token, the exception are optional variables and varag.
- *
- * There is one special case that is used in some places of Quagga that should be
- * pointed out here shortly. An example would be "password (8|) WORD". This
- * construct is used to have fixed strings communicated as arguments. (The "8"
- * will be passed down as an argument in this case) It does not mean that
- * the "8" is optional. Another historic and possibly surprising property of
- * this construct is that it consumes two parts of helpstr. (Help
- * strings will be explained later)
- *
- * Keyword Tokens:
- *
- * There are commands that take a lot of different and possibly optional arguments.
- * An example from ospf would be the "default-information originate" command. This
- * command takes a lot of optional arguments that may be provided in any order.
- * To accomodate such commands, the Keyword Token has been implemented.
- * Using the keyword token, the "default-information originate" command and all
- * its possible options can be represented using this single cmdstr:
- * "default-information originate \
- * {always|metric <0-16777214>|metric-type (1|2)|route-map WORD}"
- *
- * Keywords always start with a fixed string and may be followed by arguments.
- * Except optional variables and vararg, everything is permitted here.
- *
- * For the special case of a keyword without arguments, either NULL or the
- * keyword itself will be pushed as an argument, depending on whether the
- * keyword is present.
- * For the other keywords, arguments will be only pushed for
- * variables/Multiple Tokens. If the keyword is not present, the arguments that
- * would have been pushed will be substituted by NULL.
- *
- * A few examples:
- * "default information originate metric-type 1 metric 1000"
- * would yield the following arguments:
- * { NULL, "1000", "1", NULL }
- *
- * "default information originate always route-map RMAP-DEFAULT"
- * would yield the following arguments:
- * { "always", NULL, NULL, "RMAP-DEFAULT" }
- *
- * helpstr
- * =======
- *
- * The helpstr is used to show a short explantion for the commands that
- * are available when the user presses '?' on the CLI. It is the concatenation
- * of the helpstrings for all the tokens that make up the command.
- *
- * There should be one helpstring for each token in the cmdstr except those
- * containing other tokens, like Multiple or Keyword Tokens. For those, there
- * will only be the helpstrings of the contained tokens.
- *
- * The individual helpstrings are expected to be in the same order as their
- * respective Tokens appear in the cmdstr. They should each be terminated with
- * a linefeed. The last helpstring should be terminated with a linefeed as well.
- *
- * Care should also be taken to avoid having similar tokens with different
- * helpstrings. Imagine e.g. the commands "show ip ospf" and "show ip bgp".
- * they both contain a helpstring for "show", but only one will be displayed
- * when the user enters "sh?". If those two helpstrings differ, it is not
- * defined which one will be shown and the behavior is therefore unpredictable.
