491 "Search or modify authentication backends according to SPEC.
493 This function parses `auth-sources' for matches of the SPEC
494 plist. It can optionally create or update an authentication
495 token if requested. A token is just a standard Emacs property
496 list with a :secret property that can be a function; all the
497 other properties will always hold scalar values.
499 Typically the :secret property, if present, contains a password.
501 Common search keys are :max, :host, :port, and :user. In
502 addition, :create specifies how tokens will be or created.
503 Finally, :type can specify which backend types you want to check.
505 A string value is always matched literally. A symbol is matched
506 as its string value, literally. All the SPEC values can be
507 single values (symbol or string) or lists thereof (in which case
508 any of the search terms matches).
510 :create t means to create a token if possible.
512 A new token will be created if no matching tokens were found.
513 The new token will have only the keys the backend requires. For
514 the netrc backend, for instance, that's the user, host, and
519 \(let ((auth-source-creation-defaults '((user . \"defaultUser\")
520 (A . \"default A\"))))
521 (auth-source-search :host \"mine\" :type 'netrc :max 1
522 :P \"pppp\" :Q \"qqqq\"
527 \"Search for any entry matching host 'mine' in backends of type
528 'netrc', maximum one result.
530 Create a new entry if you found none. The netrc backend will
531 automatically require host, user, and port. The host will be
532 'mine'. We prompt for the user with default 'defaultUser' and
533 for the port without a default. We will not prompt for A, Q,
534 or P. The resulting token will only have keys user, host, and
537 :create '(A B C) also means to create a token if possible.
539 The behavior is like :create t but if the list contains any
540 parameter, that parameter will be required in the resulting
541 token. The value for that parameter will be obtained from the
542 search parameters or from user input. If any queries are needed,
543 the alist `auth-source-creation-defaults' will be checked for the
544 default value. If the user, host, or port are missing, the alist
545 `auth-source-creation-prompts' will be used to look up the
546 prompts IN THAT ORDER (so the 'user prompt will be queried first,
547 then 'host, then 'port, and finally 'secret). Each prompt string
548 can use %u, %h, and %p to show the user, host, and port.
552 \(let ((auth-source-creation-defaults '((user . \"defaultUser\")
553 (A . \"default A\")))
554 (auth-source-creation-prompts
555 '((password . \"Enter IMAP password for %h:%p: \"))))
556 (auth-source-search :host '(\"nonesuch\" \"twosuch\") :type 'netrc :max 1
557 :P \"pppp\" :Q \"qqqq\"
562 \"Search for any entry matching host 'nonesuch'
563 or 'twosuch' in backends of type 'netrc', maximum one result.
565 Create a new entry if you found none. The netrc backend will
566 automatically require host, user, and port. The host will be
567 'nonesuch' and Q will be 'qqqq'. We prompt for the password
568 with the shown prompt. We will not prompt for Q. The resulting
569 token will have keys user, host, port, A, B, and Q. It will not
570 have P with any value, even though P is used in the search to
571 find only entries that have P set to 'pppp'.\"
573 When multiple values are specified in the search parameter, the
574 user is prompted for which one. So :host (X Y Z) would ask the
575 user to choose between X, Y, and Z.
577 This creation can fail if the search was not specific enough to
578 create a new token (it's up to the backend to decide that). You
579 should `catch' the backend-specific error as usual. Some
580 backends (netrc, at least) will prompt the user rather than throw
583 :require (A B C) means that only results that contain those
584 tokens will be returned. Thus for instance requiring :secret
585 will ensure that any results will actually have a :secret
588 :delete t means to delete any found entries. nil by default.
589 Use `auth-source-delete' in ELisp code instead of calling
590 `auth-source-search' directly with this parameter.
592 :type (X Y Z) will check only those backend types. 'netrc and
593 'secrets are the only ones supported right now.
595 :max N means to try to return at most N items (defaults to 1).
596 When 0 the function will return just t or nil to indicate if any
597 matches were found. More than N items may be returned, depending
598 on the search and the backend.
600 :host (X Y Z) means to match only hosts X, Y, or Z according to
601 the match rules above. Defaults to t.
603 :user (X Y Z) means to match only users X, Y, or Z according to
604 the match rules above. Defaults to t.
606 :port (P Q R) means to match only protocols P, Q, or R.
609 :K (V1 V2 V3) for any other key K will match values V1, V2, or
610 V3 (note the match rules above).
612 The return value is a list with at most :max tokens. Each token
613 is a plist with keys :backend :host :port :user, plus any other
614 keys provided by the backend (notably :secret). But note the
615 exception for :max 0, which see above.
617 The token can hold a :save-function key. If you call that, the
618 user will be prompted to save the data to the backend. You can't
619 request that this should happen right after creation, because
620 `auth-source-search' has no way of knowing if the token is
621 actually useful. So the caller must arrange to call this function.
623 The token's :secret key can hold a function. In that case you
624 must call it to obtain the actual value."
