894 | The optional second arg INITIAL-CONTENTS is an obsolete alternative to |
895 | DEFAULT-VALUE. It normally should be nil in new code, except when | |
896 | HIST is a cons. It is discussed in more detail below. | |
a1f17501 PJ |
897 | Third arg KEYMAP is a keymap to use whilst reading; |
898 | if omitted or nil, the default is `minibuffer-local-map'. | |
fd771ceb | 899 | If fourth arg READ is non-nil, then interpret the result as a Lisp object |
a1f17501 PJ |
900 | and return that object: |
901 | in other words, do `(car (read-from-string INPUT-STRING))' | |
6b61353c KH |
902 | Fifth arg HIST, if non-nil, specifies a history list and optionally |
903 | the initial position in the list. It can be a symbol, which is the | |
904 | history list variable to use, or it can be a cons cell | |
905 | (HISTVAR . HISTPOS). In that case, HISTVAR is the history list variable | |
906 | to use, and HISTPOS is the initial position for use by the minibuffer | |
907 | history commands. For consistency, you should also specify that | |
908 | element of the history as the value of INITIAL-CONTENTS. Positions | |
909 | are counted starting from 1 at the beginning of the list. | |
2e3148e2 JL |
910 | Sixth arg DEFAULT-VALUE is the default value or the list of default values. |
911 | If non-nil, it is available for history commands, and as the value | |
912 | (or the first element of the list of default values) to return | |
913 | if the user enters the empty string. But, unless READ is non-nil, | |
914 | `read-from-minibuffer' does NOT return DEFAULT-VALUE if the user enters | |
915 | empty input! It returns the empty string. | |
a1f17501 | 916 | Seventh arg INHERIT-INPUT-METHOD, if non-nil, means the minibuffer inherits |
029a305c | 917 | the current input method and the setting of `enable-multibyte-characters'. |
a1f17501 PJ |
918 | If the variable `minibuffer-allow-text-properties' is non-nil, |
919 | then the string which is returned includes whatever text properties | |
6b61353c KH |
920 | were present in the minibuffer. Otherwise the value has no text properties. |
921 | ||
922 | The remainder of this documentation string describes the | |
923 | INITIAL-CONTENTS argument in more detail. It is only relevant when | |
924 | studying existing code, or when HIST is a cons. If non-nil, | |
925 | INITIAL-CONTENTS is a string to be inserted into the minibuffer before | |
926 | reading input. Normally, point is put at the end of that string. | |
927 | However, if INITIAL-CONTENTS is \(STRING . POSITION), the initial | |
928 | input is STRING, but point is placed at _one-indexed_ position | |
929 | POSITION in the minibuffer. Any integer value less than or equal to | |
930 | one puts point at the beginning of the string. *Note* that this | |
931 | behavior differs from the way such arguments are used in `completing-read' | |
932 | and some related functions, which use zero-indexing for POSITION. */) | |

1460 | If COLLECTION is an alist, the keys (cars of elements) are the |
1461 | possible completions. If an element is not a cons cell, then the | |
1462 | element itself is the possible completion. | |
1463 | If COLLECTION is a hash-table, all the keys that are strings or symbols | |
1464 | are the possible completions. | |
1465 | If COLLECTION is an obarray, the names of all symbols in the obarray | |
1466 | are the possible completions. | |

a284cdbb | 1468 | COLLECTION can also be a function to do the completion itself. |
a1f17501 PJ |
1469 | It receives three arguments: the values STRING, PREDICATE and t. |
1470 | Whatever it returns becomes the value of `all-completions'. | |
1471 | ||
1472 | If optional third argument PREDICATE is non-nil, | |
1473 | it is used to test each possible match. | |
1474 | The match is a candidate only if PREDICATE returns non-nil. | |
1475 | The argument given to PREDICATE is the alist element | |
a284cdbb | 1476 | or the symbol from the obarray. If COLLECTION is a hash-table, |
85cd4372 | 1477 | predicate is called with two arguments: the key and the value. |
a1f17501 PJ |
1478 | Additionally to this predicate, `completion-regexp-list' |
1479 | is used to further constrain the set of candidates. | |
1480 | ||
782a943e | 1481 | An obsolete optional fourth argument HIDE-SPACES is still accepted for |
057bce6f | 1482 | backward compatibility. If non-nil, strings in COLLECTION that start |
4fcc3d32 | 1483 | with a space are ignored unless STRING itself starts with a space. */) |

1650 | to confirm her choice if the input is not an element of COLLECTION. | |
1651 | - `confirm-after-completion' means that the user can exit with any | |
1652 | input, but she needs to confirm her choice if she called | |
1653 | `minibuffer-complete' right before `minibuffer-complete-and-exit' | |
1654 | and the input is not an element of COLLECTION. | |

1666 | that this is different from `read-from-minibuffer' and related | |

1675 | that case, HISTVAR is the history list variable to use, and HISTPOS | |
1676 | is the initial position (the position in the list used by the | |
1677 | minibuffer history commands). For consistency, you should also | |
1678 | specify that element of the history as the value of | |
1fb101f3 | 1679 | INITIAL-INPUT. (This is the only case in which you should use |
