| * DEFUN(funcname, cmdname, cmdstr, helpstr) |
| * |
| * funcname |
| * ======== |

| * |
| * 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 |

| * uppercase = "A" | ... | "Z" ; |
| * digit = "0" | ... | "9" ; |
| * number = digit , { digit } ; |
| * |
| * fixed_string = (lowercase | digit) , { lowercase | digit | uppercase | "-" | "_" } ; |

| * ipv4 = "A.B.C.D" ; |
| * ipv4_prefix = "A.B.C.D/M" ; |

| * 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. |
