901 | The optional second arg INITIAL-CONTENTS is an obsolete alternative to |
902 | DEFAULT-VALUE. It normally should be nil in new code, except when | |
903 | HIST is a cons. It is discussed in more detail below. | |
a1f17501 PJ |
904 | Third arg KEYMAP is a keymap to use whilst reading; |
905 | if omitted or nil, the default is `minibuffer-local-map'. | |
fd771ceb | 906 | If fourth arg READ is non-nil, then interpret the result as a Lisp object |
a1f17501 PJ |
907 | and return that object: |
908 | in other words, do `(car (read-from-string INPUT-STRING))' | |
6b61353c KH |
909 | Fifth arg HIST, if non-nil, specifies a history list and optionally |
910 | the initial position in the list. It can be a symbol, which is the | |
911 | history list variable to use, or it can be a cons cell | |
912 | (HISTVAR . HISTPOS). In that case, HISTVAR is the history list variable | |
913 | to use, and HISTPOS is the initial position for use by the minibuffer | |
914 | history commands. For consistency, you should also specify that | |
915 | element of the history as the value of INITIAL-CONTENTS. Positions | |
916 | are counted starting from 1 at the beginning of the list. | |
20f53c69 CY |
917 | Sixth arg DEFAULT-VALUE is a default value or list of default values. |
918 | If non-nil, it is available via history commands. If READ is | |
919 | non-nil, it is also the default to `read' if the user enters empty | |
920 | input. If READ is non-nil, `read-from-minibuffer' does NOT return | |
921 | DEFAULT-VALUE for empty input! It returns the empty string. | |
a1f17501 | 922 | Seventh arg INHERIT-INPUT-METHOD, if non-nil, means the minibuffer inherits |
029a305c | 923 | the current input method and the setting of `enable-multibyte-characters'. |
a1f17501 PJ |
924 | If the variable `minibuffer-allow-text-properties' is non-nil, |
925 | then the string which is returned includes whatever text properties | |
6b61353c KH |
926 | were present in the minibuffer. Otherwise the value has no text properties. |
927 | ||
928 | The remainder of this documentation string describes the | |
929 | INITIAL-CONTENTS argument in more detail. It is only relevant when | |
930 | studying existing code, or when HIST is a cons. If non-nil, | |
931 | INITIAL-CONTENTS is a string to be inserted into the minibuffer before | |
932 | reading input. Normally, point is put at the end of that string. | |
933 | However, if INITIAL-CONTENTS is \(STRING . POSITION), the initial | |
934 | input is STRING, but point is placed at _one-indexed_ position | |
935 | POSITION in the minibuffer. Any integer value less than or equal to | |
936 | one puts point at the beginning of the string. *Note* that this | |
937 | behavior differs from the way such arguments are used in `completing-read' | |
938 | and some related functions, which use zero-indexing for POSITION. */) | |

1466 | If COLLECTION is an alist, the keys (cars of elements) are the |
1467 | possible completions. If an element is not a cons cell, then the | |
1468 | element itself is the possible completion. | |
1469 | If COLLECTION is a hash-table, all the keys that are strings or symbols | |
1470 | are the possible completions. | |
1471 | If COLLECTION is an obarray, the names of all symbols in the obarray | |
1472 | are the possible completions. | |

1475 | It receives three arguments: the values STRING, PREDICATE and t. |
1476 | Whatever it returns becomes the value of `all-completions'. | |
1477 | ||
1478 | If optional third argument PREDICATE is non-nil, | |
1479 | it is used to test each possible match. | |
1480 | The match is a candidate only if PREDICATE returns non-nil. | |
1481 | The argument given to PREDICATE is the alist element | |
a284cdbb | 1482 | or the symbol from the obarray. If COLLECTION is a hash-table, |
85cd4372 | 1483 | predicate is called with two arguments: the key and the value. |
a1f17501 PJ |
1484 | Additionally to this predicate, `completion-regexp-list' |
1485 | is used to further constrain the set of candidates. | |
1486 | ||
782a943e | 1487 | An obsolete optional fourth argument HIDE-SPACES is still accepted for |
057bce6f | 1488 | backward compatibility. If non-nil, strings in COLLECTION that start |

1656 | to confirm her choice if the input is not an element of COLLECTION. | |
1657 | - `confirm-after-completion' means that the user can exit with any | |
1658 | input, but she needs to confirm her choice if she called | |
1659 | `minibuffer-complete' right before `minibuffer-complete-and-exit' | |
1660 | and the input is not an element of COLLECTION. | |

1672 | that this is different from `read-from-minibuffer' and related | |

1674 | deprecated--it is best to pass nil for INITIAL-INPUT and supply the | |

1681 | that case, HISTVAR is the history list variable to use, and HISTPOS | |
1682 | is the initial position (the position in the list used by the | |
1683 | minibuffer history commands). For consistency, you should also | |
1684 | specify that element of the history as the value of | |
1fb101f3 | 1685 | INITIAL-INPUT. (This is the only case in which you should use |
