459 "Search or modify authentication backends according to SPEC.
461 This function parses `auth-sources' for matches of the SPEC
462 plist. It can optionally create or update an authentication
463 token if requested. A token is just a standard Emacs property
464 list with a :secret property that can be a function; all the
465 other properties will always hold scalar values.
467 Typically the :secret property, if present, contains a password.
469 Common search keys are :max, :host, :port, and :user. In
470 addition, :create specifies how tokens will be or created.
471 Finally, :type can specify which backend types you want to check.
473 A string value is always matched literally. A symbol is matched
474 as its string value, literally. All the SPEC values can be
475 single values (symbol or string) or lists thereof (in which case
476 any of the search terms matches).
478 :create t means to create a token if possible.
480 A new token will be created if no matching tokens were found.
481 The new token will have only the keys the backend requires. For
482 the netrc backend, for instance, that's the user, host, and
487 \(let ((auth-source-creation-defaults '((user . \"defaultUser\")
488 (A . \"default A\"))))
489 (auth-source-search :host \"mine\" :type 'netrc :max 1
490 :P \"pppp\" :Q \"qqqq\"
495 \"Search for any entry matching host 'mine' in backends of type
496 'netrc', maximum one result.
498 Create a new entry if you found none. The netrc backend will
499 automatically require host, user, and port. The host will be
500 'mine'. We prompt for the user with default 'defaultUser' and
501 for the port without a default. We will not prompt for A, Q,
502 or P. The resulting token will only have keys user, host, and
505 :create '(A B C) also means to create a token if possible.
507 The behavior is like :create t but if the list contains any
508 parameter, that parameter will be required in the resulting
509 token. The value for that parameter will be obtained from the
510 search parameters or from user input. If any queries are needed,
511 the alist `auth-source-creation-defaults' will be checked for the
512 default value. If the user, host, or port are missing, the alist
513 `auth-source-creation-prompts' will be used to look up the
514 prompts IN THAT ORDER (so the 'user prompt will be queried first,
515 then 'host, then 'port, and finally 'secret). Each prompt string
516 can use %u, %h, and %p to show the user, host, and port.
520 \(let ((auth-source-creation-defaults '((user . \"defaultUser\")
521 (A . \"default A\")))
522 (auth-source-creation-prompts
523 '((password . \"Enter IMAP password for %h:%p: \"))))
524 (auth-source-search :host '(\"nonesuch\" \"twosuch\") :type 'netrc :max 1
525 :P \"pppp\" :Q \"qqqq\"
530 \"Search for any entry matching host 'nonesuch'
531 or 'twosuch' in backends of type 'netrc', maximum one result.
533 Create a new entry if you found none. The netrc backend will
534 automatically require host, user, and port. The host will be
535 'nonesuch' and Q will be 'qqqq'. We prompt for the password
536 with the shown prompt. We will not prompt for Q. The resulting
537 token will have keys user, host, port, A, B, and Q. It will not
538 have P with any value, even though P is used in the search to
539 find only entries that have P set to 'pppp'.\"
541 When multiple values are specified in the search parameter, the
542 user is prompted for which one. So :host (X Y Z) would ask the
543 user to choose between X, Y, and Z.
545 This creation can fail if the search was not specific enough to
546 create a new token (it's up to the backend to decide that). You
547 should `catch' the backend-specific error as usual. Some
548 backends (netrc, at least) will prompt the user rather than throw
551 :require (A B C) means that only results that contain those
552 tokens will be returned. Thus for instance requiring :secret
553 will ensure that any results will actually have a :secret
556 :delete t means to delete any found entries. nil by default.
557 Use `auth-source-delete' in ELisp code instead of calling
558 `auth-source-search' directly with this parameter.
560 :type (X Y Z) will check only those backend types. 'netrc and
561 'secrets are the only ones supported right now.
563 :max N means to try to return at most N items (defaults to 1).
564 When 0 the function will return just t or nil to indicate if any
565 matches were found. More than N items may be returned, depending
566 on the search and the backend.
568 :host (X Y Z) means to match only hosts X, Y, or Z according to
569 the match rules above. Defaults to t.
571 :user (X Y Z) means to match only users X, Y, or Z according to
572 the match rules above. Defaults to t.
574 :port (P Q R) means to match only protocols P, Q, or R.
577 :K (V1 V2 V3) for any other key K will match values V1, V2, or
578 V3 (note the match rules above).
580 The return value is a list with at most :max tokens. Each token
581 is a plist with keys :backend :host :port :user, plus any other
582 keys provided by the backend (notably :secret). But note the
583 exception for :max 0, which see above.
585 The token can hold a :save-function key. If you call that, the
586 user will be prompted to save the data to the backend. You can't
587 request that this should happen right after creation, because
588 `auth-source-search' has no way of knowing if the token is
589 actually useful. So the caller must arrange to call this function.
591 The token's :secret key can hold a function. In that case you
592 must call it to obtain the actual value."
