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 | |

555 | ||
556 | This function parses `auth-sources' for matches of the SPEC | |
557 | plist. It can optionally create or update an authentication | |
558 | token if requested. A token is just a standard Emacs property | |
559 | list with a :secret property that can be a function; all the | |
560 | other properties will always hold scalar values. | |
561 | ||
562 | Typically the :secret property, if present, contains a password. | |
563 | ||
35123c04 | 564 | Common search keys are :max, :host, :port, and :user. In |
b8e0f0cd G |
565 | addition, :create specifies how tokens will be or created. |
566 | Finally, :type can specify which backend types you want to check. | |
567 | ||
568 | A string value is always matched literally. A symbol is matched | |
569 | as its string value, literally. All the SPEC values can be | |
570 | single values (symbol or string) or lists thereof (in which case | |
571 | any of the search terms matches). | |
572 | ||
573 | :create t means to create a token if possible. | |
574 | ||
575 | A new token will be created if no matching tokens were found. | |
576 | The new token will have only the keys the backend requires. For | |
577 | the netrc backend, for instance, that's the user, host, and | |
35123c04 | 578 | port keys. |
b8e0f0cd G |
579 | |
580 | Here's an example: | |
581 | ||
582 | \(let ((auth-source-creation-defaults '((user . \"defaultUser\") | |
583 | (A . \"default A\")))) | |
584 | (auth-source-search :host \"mine\" :type 'netrc :max 1 | |
585 | :P \"pppp\" :Q \"qqqq\" | |
586 | :create t)) | |
587 | ||
588 | which says: | |
589 | ||
590 | \"Search for any entry matching host 'mine' in backends of type | |
591 | 'netrc', maximum one result. | |
592 | ||
593 | Create a new entry if you found none. The netrc backend will | |
35123c04 | 594 | automatically require host, user, and port. The host will be |
b8e0f0cd | 595 | 'mine'. We prompt for the user with default 'defaultUser' and |
35123c04 | 596 | for the port without a default. We will not prompt for A, Q, |
b8e0f0cd | 597 | or P. The resulting token will only have keys user, host, and |
35123c04 | 598 | port.\" |
b8e0f0cd G |
599 | |
600 | :create '(A B C) also means to create a token if possible. | |
601 | ||
602 | The behavior is like :create t but if the list contains any | |
603 | parameter, that parameter will be required in the resulting | |
604 | token. The value for that parameter will be obtained from the | |
605 | search parameters or from user input. If any queries are needed, | |
606 | the alist `auth-source-creation-defaults' will be checked for the | |
003522ce G |
607 | default value. If the user, host, or port are missing, the alist |
608 | `auth-source-creation-prompts' will be used to look up the | |
609 | prompts IN THAT ORDER (so the 'user prompt will be queried first, | |
610 | then 'host, then 'port, and finally 'secret). Each prompt string | |
611 | can use %u, %h, and %p to show the user, host, and port. | |
b8e0f0cd G |
612 | |
613 | Here's an example: | |
614 | ||
615 | \(let ((auth-source-creation-defaults '((user . \"defaultUser\") | |
003522ce G |
616 | (A . \"default A\"))) |
617 | (auth-source-creation-prompts | |
618 | '((password . \"Enter IMAP password for %h:%p: \")))) | |
b8e0f0cd G |
619 | (auth-source-search :host '(\"nonesuch\" \"twosuch\") :type 'netrc :max 1 |
620 | :P \"pppp\" :Q \"qqqq\" | |
621 | :create '(A B Q))) | |
622 | ||
623 | which says: | |
624 | ||
625 | \"Search for any entry matching host 'nonesuch' | |
626 | or 'twosuch' in backends of type 'netrc', maximum one result. | |
627 | ||
628 | Create a new entry if you found none. The netrc backend will | |
35123c04 | 629 | automatically require host, user, and port. The host will be |
003522ce G |
630 | 'nonesuch' and Q will be 'qqqq'. We prompt for the password |
631 | with the shown prompt. We will not prompt for Q. The resulting | |
632 | token will have keys user, host, port, A, B, and Q. It will not | |
633 | have P with any value, even though P is used in the search to | |
634 | find only entries that have P set to 'pppp'.\" | |
b8e0f0cd G |
635 | |
636 | When multiple values are specified in the search parameter, the | |
7ba93e94 G |
637 | user is prompted for which one. So :host (X Y Z) would ask the |
638 | user to choose between X, Y, and Z. | |
b8e0f0cd G |
639 | |
640 | This creation can fail if the search was not specific enough to | |
641 | create a new token (it's up to the backend to decide that). You | |
642 | should `catch' the backend-specific error as usual. Some | |
643 | backends (netrc, at least) will prompt the user rather than throw | |
644 | an error. | |
645 | ||
733afdf4 TZ |
646 | :require (A B C) means that only results that contain those |
647 | tokens will be returned. Thus for instance requiring :secret | |
648 | will ensure that any results will actually have a :secret | |
649 | property. | |
650 | ||
b8e0f0cd G |
651 | :delete t means to delete any found entries. nil by default. |
652 | Use `auth-source-delete' in ELisp code instead of calling | |
653 | `auth-source-search' directly with this parameter. | |
654 | ||
655 | :type (X Y Z) will check only those backend types. 'netrc and | |
656 | 'secrets are the only ones supported right now. | |
657 | ||
658 | :max N means to try to return at most N items (defaults to 1). | |
659 | When 0 the function will return just t or nil to indicate if any | |
660 | matches were found. More than N items may be returned, depending | |
661 | on the search and the backend. | |
662 | ||
663 | :host (X Y Z) means to match only hosts X, Y, or Z according to | |
664 | the match rules above. Defaults to t. | |
665 | ||
666 | :user (X Y Z) means to match only users X, Y, or Z according to | |
667 | the match rules above. Defaults to t. | |
668 | ||
35123c04 | 669 | :port (P Q R) means to match only protocols P, Q, or R. |
b8e0f0cd G |
670 | Defaults to t. |
671 | ||
672 | :K (V1 V2 V3) for any other key K will match values V1, V2, or | |
673 | V3 (note the match rules above). | |
674 | ||
675 | The return value is a list with at most :max tokens. Each token | |
35123c04 | 676 | is a plist with keys :backend :host :port :user, plus any other |
b8e0f0cd G |
677 | keys provided by the backend (notably :secret). But note the |
678 | exception for :max 0, which see above. | |
679 | ||
733afdf4 TZ |
680 | The token can hold a :save-function key. If you call that, the |
681 | user will be prompted to save the data to the backend. You can't | |
682 | request that this should happen right after creation, because | |
683 | `auth-source-search' has no way of knowing if the token is | |
684 | actually useful. So the caller must arrange to call this function. | |
685 | ||
b8e0f0cd G |
686 | The token's :secret key can hold a function. In that case you |
687 | must call it to obtain the actual value." | |

1651 | For the generic keychain type, the :label key searches the item's | |

1653 | Similarly, :host maps to \"-c HOST\" (the \"creator\" keychain | |
