223 | * | |
224 | * cmdstr | |
225 | * ====== | |
226 | * | |
227 | * The cmdstr defines the command syntax. It is used by the vty subsystem | |
228 | * and vtysh to perform matching and completion in the cli. So you have to take | |
229 | * care to construct it adhering to the following grammar. The names used | |
230 | * for the production rules losely represent the names used in lib/command.c | |
231 | * | |
232 | * cmdstr = cmd_token , { " " , cmd_token } ; | |
233 | * | |
234 | * cmd_token = cmd_terminal | |
235 | * | cmd_multiple | |
236 | * | cmd_keyword ; | |
237 | * | |
238 | * cmd_terminal_fixed = fixed_string | |
239 | * | variable | |
240 | * | range | |
241 | * | ipv4 | |
242 | * | ipv4_prefix | |
243 | * | ipv6 | |
244 | * | ipv6_prefix ; | |
245 | * | |
246 | * cmd_terminal = cmd_terminal_fixed | |
247 | * | option | |
248 | * | vararg ; | |
249 | * | |
250 | * multiple_part = cmd_terminal_fixed ; | |
251 | * cmd_multiple = "(" , multiple_part , ( "|" | { "|" , multiple_part } ) , ")" ; | |
252 | * | |
253 | * keyword_part = fixed_string , { " " , ( cmd_terminal_fixed | cmd_multiple ) } ; | |
254 | * cmd_keyword = "{" , keyword_part , { "|" , keyword_part } , "}" ; | |
255 | * | |
256 | * lowercase = "a" | ... | "z" ; | |
257 | * uppercase = "A" | ... | "Z" ; | |
258 | * digit = "0" | ... | "9" ; | |
259 | * number = digit , { digit } ; | |
260 | * | |
261 | * fixed_string = (lowercase | digit) , { lowercase | digit | uppercase | "-" | "_" } ; | |
262 | * variable = uppercase , { uppercase | "_" } ; | |
263 | * range = "<" , number , "-" , number , ">" ; | |
264 | * ipv4 = "A.B.C.D" ; | |
265 | * ipv4_prefix = "A.B.C.D/M" ; | |
266 | * ipv6 = "X:X::X:X" ; | |
267 | * ipv6_prefix = "X:X::X:X/M" ; | |
268 | * option = "[" , variable , "]" ; | |
269 | * vararg = "." , variable ; | |
270 | * | |
271 | * To put that all in a textual description: A cmdstr is a sequence of tokens, | |
272 | * separated by spaces. | |
273 | * | |
274 | * Terminal Tokens: | |
275 | * | |
276 | * A very simple cmdstring would be something like: "show ip bgp". It consists | |
277 | * of three Terminal Tokens, each containing a fixed string. When this command | |
278 | * is called, no arguments will be passed down to the function implementing it, | |
279 | * as it only consists of fixed strings. | |
280 | * | |
281 | * Apart from fixed strings, Terminal Tokens can also contain variables: | |
282 | * An example would be "show ip bgp A.B.C.D". This command expects an IPv4 | |
283 | * as argument. As this is a variable, the IP address entered by the user will | |
284 | * be passed down as an argument. Apart from two exceptions, the other options | |
285 | * for Terminal Tokens behave exactly as we just discussed and only make a | |
286 | * difference for the CLI. The two exceptions will be discussed in the next | |
287 | * paragraphs. | |
288 | * | |
289 | * A Terminal Token can contain a so called option match. This is a simple | |
290 | * string variable that the user may omit. An example would be: | |
291 | * "show interface [IFNAME]". If the user calls this without an interface as | |
292 | * argument, no arguments will be passed down to the function implementing | |
293 | * this command. Otherwise, the interface name will be provided to the function | |
294 | * as a regular argument. | |
295 | ||
296 | * Also, a Terminal Token can contain a so called vararg. This is used e.g. in | |
297 | * "show ip bgp regexp .LINE". The last token is a vararg match and will | |
298 | * consume all the arguments the user inputs on the command line and append | |
299 | * those to the list of arguments passed down to the function implementing this | |
300 | * command. (Therefore, it doesn't make much sense to have any tokens after a | |
301 | * vararg because the vararg will already consume all the words the user entered | |
302 | * in the CLI) | |
303 | * | |
304 | * Multiple Tokens: | |
305 | * | |
306 | * The Multiple Token type can be used if there are multiple possibilities what | |
307 | * arguments may be used for a command, but it should map to the same function | |
308 | * nonetheless. An example would be "ip route A.B.C.D/M (reject|blackhole)" | |
309 | * In that case both "reject" and "blackhole" would be acceptable as last | |
310 | * arguments. The words matched by Multiple Tokens are always added to the | |
311 | * argument list, even if they are matched by fixed strings. Such a Multiple | |
312 | * Token can contain almost any type of token that would also be acceptable | |
313 | * for a Terminal Token, the exception are optional variables and varag. | |
314 | * | |
315 | * There is one special case that is used in some places of Quagga that should be | |
316 | * pointed out here shortly. An example would be "password (8|) WORD". This | |
317 | * construct is used to have fixed strings communicated as arguments. (The "8" | |
318 | * will be passed down as an argument in this case) It does not mean that | |
319 | * the "8" is optional. Another historic and possibly surprising property of | |
320 | * this construct is that it consumes two parts of helpstr. (Help | |
321 | * strings will be explained later) | |
322 | * | |
323 | * Keyword Tokens: | |
324 | * | |
325 | * There are commands that take a lot of different and possibly optional arguments. | |
326 | * An example from ospf would be the "default-information originate" command. This | |
327 | * command takes a lot of optional arguments that may be provided in any order. | |
328 | * To accomodate such commands, the Keyword Token has been implemented. | |
329 | * Using the keyword token, the "default-information originate" command and all | |
330 | * its possible options can be represented using this single cmdstr: | |
331 | * "default-information originate \ | |
332 | * {always|metric <0-16777214>|metric-type (1|2)|route-map WORD}" | |
333 | * | |
334 | * Keywords always start with a fixed string and may be followed by arguments. | |
335 | * Except optional variables and vararg, everything is permitted here. | |
336 | * | |
337 | * For the special case of a keyword without arguments, either NULL or the | |
338 | * keyword itself will be pushed as an argument, depending on whether the | |
339 | * keyword is present. | |
340 | * For the other keywords, arguments will be only pushed for | |
341 | * variables/Multiple Tokens. If the keyword is not present, the arguments that | |
342 | * would have been pushed will be substituted by NULL. | |
343 | * | |
344 | * A few examples: | |
345 | * "default information originate metric-type 1 metric 1000" | |
346 | * would yield the following arguments: | |
347 | * { NULL, "1000", "1", NULL } | |
348 | * | |
349 | * "default information originate always route-map RMAP-DEFAULT" | |
350 | * would yield the following arguments: | |
351 | * { "always", NULL, NULL, "RMAP-DEFAULT" } | |
352 | * | |
353 | * helpstr | |
354 | * ======= | |
355 | * | |
356 | * The helpstr is used to show a short explantion for the commands that | |
357 | * are available when the user presses '?' on the CLI. It is the concatenation | |
358 | * of the helpstrings for all the tokens that make up the command. | |
359 | * | |
360 | * There should be one helpstring for each token in the cmdstr except those | |
361 | * containing other tokens, like Multiple or Keyword Tokens. For those, there | |
362 | * will only be the helpstrings of the contained tokens. | |
363 | * | |
364 | * The individual helpstrings are expected to be in the same order as their | |
365 | * respective Tokens appear in the cmdstr. They should each be terminated with | |
366 | * a linefeed. The last helpstring should be terminated with a linefeed as well. | |
367 | * | |
368 | * Care should also be taken to avoid having similar tokens with different | |
369 | * helpstrings. Imagine e.g. the commands "show ip ospf" and "show ip bgp". | |
370 | * they both contain a helpstring for "show", but only one will be displayed | |
371 | * when the user enters "sh?". If those two helpstrings differ, it is not | |
372 | * defined which one will be shown and the behavior is therefore unpredictable. | |
