25 | ;; This is the auth-source.el package. It lets users tell Gnus how to | |
26 | ;; authenticate in a single place. Simplicity is the goal. Instead | |
27 | ;; of providing 5000 options, we'll stick to simple, easy to | |
28 | ;; understand options. | |

34 | ;; - never decode the backend file unless it's necessary | |
35 | ;; - a more generic way to match backends and search backend contents | |
36 | ;; - absorb netrc.el and simplify it | |
37 | ;; - protect passwords better | |
38 | ;; - allow creating and changing netrc lines (not files) e.g. change a password | |

355 | ||
356 | This function parses `auth-sources' for matches of the SPEC | |
357 | plist. It can optionally create or update an authentication | |
358 | token if requested. A token is just a standard Emacs property | |
359 | list with a :secret property that can be a function; all the | |
360 | other properties will always hold scalar values. | |
361 | ||
362 | Typically the :secret property, if present, contains a password. | |
363 | ||
364 | Common search keys are :max, :host, :protocol, and :user. In | |
365 | addition, :create specifies how tokens will be or created. | |
366 | Finally, :type can specify which backend types you want to check. | |
367 | ||
368 | A string value is always matched literally. A symbol is matched | |
369 | as its string value, literally. All the SPEC values can be | |
370 | single values (symbol or string) or lists thereof (in which case | |
371 | any of the search terms matches). | |
372 | ||
373 | :create t means to create a token if possible. | |
374 | ||
375 | A new token will be created if no matching tokens were found. | |
376 | The new token will have only the keys the backend requires. For | |
377 | the netrc backend, for instance, that's the user, host, and | |
378 | protocol keys. | |
379 | ||
380 | Here's an example: | |
381 | ||
382 | \(let ((auth-source-creation-defaults '((user . \"defaultUser\") | |
383 | (A . \"default A\")))) | |
384 | (auth-source-search :host \"mine\" :type 'netrc :max 1 | |
385 | :P \"pppp\" :Q \"qqqq\" | |
386 | :create t)) | |
387 | ||
388 | which says: | |
389 | ||
390 | \"Search for any entry matching host 'mine' in backends of type | |
391 | 'netrc', maximum one result. | |
392 | ||
393 | Create a new entry if you found none. The netrc backend will | |
394 | automatically require host, user, and protocol. The host will be | |
395 | 'mine'. We prompt for the user with default 'defaultUser' and | |
396 | for the protocol without a default. We will not prompt for A, Q, | |
397 | or P. The resulting token will only have keys user, host, and | |
398 | protocol.\" | |
399 | ||
400 | :create '(A B C) also means to create a token if possible. | |
401 | ||
402 | The behavior is like :create t but if the list contains any | |
403 | parameter, that parameter will be required in the resulting | |
404 | token. The value for that parameter will be obtained from the | |
405 | search parameters or from user input. If any queries are needed, | |
406 | the alist `auth-source-creation-defaults' will be checked for the | |
407 | default prompt. | |
408 | ||
409 | Here's an example: | |
410 | ||
411 | \(let ((auth-source-creation-defaults '((user . \"defaultUser\") | |
412 | (A . \"default A\")))) | |
413 | (auth-source-search :host '(\"nonesuch\" \"twosuch\") :type 'netrc :max 1 | |
414 | :P \"pppp\" :Q \"qqqq\" | |
415 | :create '(A B Q))) | |
416 | ||
417 | which says: | |
418 | ||
419 | \"Search for any entry matching host 'nonesuch' | |
420 | or 'twosuch' in backends of type 'netrc', maximum one result. | |
421 | ||
422 | Create a new entry if you found none. The netrc backend will | |
423 | automatically require host, user, and protocol. The host will be | |
424 | 'nonesuch' and Q will be 'qqqq'. We prompt for A with default | |
425 | 'default A', for B and protocol with default nil, and for the | |
426 | user with default 'defaultUser'. We will not prompt for Q. The | |
427 | resulting token will have keys user, host, protocol, A, B, and Q. | |
428 | It will not have P with any value, even though P is used in the | |
429 | search to find only entries that have P set to 'pppp'.\" | |
430 | ||
431 | When multiple values are specified in the search parameter, the | |
432 | first one is used for creation. So :host (X Y Z) would create a | |
433 | token for host X, for instance. | |
434 | ||
435 | This creation can fail if the search was not specific enough to | |
436 | create a new token (it's up to the backend to decide that). You | |
437 | should `catch' the backend-specific error as usual. Some | |
438 | backends (netrc, at least) will prompt the user rather than throw | |
439 | an error. | |
440 | ||
441 | :delete t means to delete any found entries. nil by default. | |
442 | Use `auth-source-delete' in ELisp code instead of calling | |
443 | `auth-source-search' directly with this parameter. | |
444 | ||
445 | :type (X Y Z) will check only those backend types. 'netrc and | |
446 | 'secrets are the only ones supported right now. | |
447 | ||
448 | :max N means to try to return at most N items (defaults to 1). | |
449 | When 0 the function will return just t or nil to indicate if any | |
450 | matches were found. More than N items may be returned, depending | |
451 | on the search and the backend. | |
452 | ||
453 | :host (X Y Z) means to match only hosts X, Y, or Z according to | |
454 | the match rules above. Defaults to t. | |
455 | ||
456 | :user (X Y Z) means to match only users X, Y, or Z according to | |
457 | the match rules above. Defaults to t. | |
458 | ||
459 | :protocol (P Q R) means to match only protocols P, Q, or R. | |
460 | Defaults to t. | |
461 | ||
462 | :K (V1 V2 V3) for any other key K will match values V1, V2, or | |
463 | V3 (note the match rules above). | |
464 | ||
465 | The return value is a list with at most :max tokens. Each token | |
466 | is a plist with keys :backend :host :protocol :user, plus any other | |
467 | keys provided by the backend (notably :secret). But note the | |
468 | exception for :max 0, which see above. | |
469 | ||
470 | The token's :secret key can hold a function. In that case you | |
471 | must call it to obtain the actual value." | |
