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. - */ #define DEFUN(funcname, cmdname, cmdstr, helpstr) \ DEFUN_CMD_FUNC_DECL(funcname) \ DEFUN_CMD_ELEMENT(funcname, cmdname, cmdstr, helpstr, 0, 0) \ @@ -499,7 +337,6 @@ struct cmd_token */ #define CMD_CREATE_STR(s) CMD_CREATE_STR_HELPER(s) #define CMD_CREATE_STR_HELPER(s) #s -#define CMD_RANGE_STR(a,s) "<" CMD_CREATE_STR(a) "-" CMD_CREATE_STR(s) ">" /* Common descriptions. */ #define SHOW_STR "Show running system information\n" @@ -531,17 +368,16 @@ struct cmd_token #define IFNAME_STR "Interface name(e.g. ep0)\n" #define IP6_STR "IPv6 Information\n" #define OSPF6_STR "Open Shortest Path First (OSPF) for IPv6\n" -#define OSPF6_ROUTER_STR "Enable a routing process\n" -#define OSPF6_INSTANCE_STR "<1-65535> Instance ID\n" -#define SECONDS_STR "<1-65535> Seconds\n" +#define OSPF6_INSTANCE_STR "(1-65535) Instance ID\n" +#define SECONDS_STR "Seconds\n" #define ROUTE_STR "Routing Table\n" #define PREFIX_LIST_STR "Build a prefix list\n" #define OSPF6_DUMP_TYPE_LIST \ -"(neighbor|interface|area|lsa|zebra|config|dbex|spf|route|lsdb|redistribute|hook|asbr|prefix|abr)" +"<neighbor|interface|area|lsa|zebra|config|dbex|spf|route|lsdb|redistribute|hook|asbr|prefix|abr>" #define ISIS_STR "IS-IS information\n" #define AREA_TAG_STR "[area tag]\n" -#define COMMUNITY_AANN_STR "Community number where AA and NN are <0-65535>\n" -#define COMMUNITY_VAL_STR "Community number in AA:NN format (where AA and NN are <0-65535>) or local-AS|no-advertise|no-export|internet or additive\n" +#define COMMUNITY_AANN_STR "Community number where AA and NN are (0-65535)\n" +#define COMMUNITY_VAL_STR "Community number in AA:NN format (where AA and NN are (0-65535)) or local-AS|no-advertise|no-export|internet or additive\n" #define MPLS_TE_STR "MPLS-TE specific commands\n" #define LINK_PARAMS_STR "Configure interface link parameters\n" #define OSPF_RI_STR "OSPF Router Information specific commands\n" @@ -552,31 +388,9 @@ struct cmd_token /* IPv4 only machine should not accept IPv6 address for peer's IP address.
