883 | The optional second arg INITIAL-CONTENTS is an obsolete alternative to |
884 | DEFAULT-VALUE. It normally should be nil in new code, except when | |
885 | HIST is a cons. It is discussed in more detail below. | |
a1f17501 PJ |
886 | Third arg KEYMAP is a keymap to use whilst reading; |
887 | if omitted or nil, the default is `minibuffer-local-map'. | |
fd771ceb | 888 | If fourth arg READ is non-nil, then interpret the result as a Lisp object |
a1f17501 PJ |
889 | and return that object: |
890 | in other words, do `(car (read-from-string INPUT-STRING))' | |
6b61353c KH |
891 | Fifth arg HIST, if non-nil, specifies a history list and optionally |
892 | the initial position in the list. It can be a symbol, which is the | |
893 | history list variable to use, or it can be a cons cell | |
894 | (HISTVAR . HISTPOS). In that case, HISTVAR is the history list variable | |
895 | to use, and HISTPOS is the initial position for use by the minibuffer | |
896 | history commands. For consistency, you should also specify that | |
897 | element of the history as the value of INITIAL-CONTENTS. Positions | |
898 | are counted starting from 1 at the beginning of the list. | |
2e3148e2 JL |
899 | Sixth arg DEFAULT-VALUE is the default value or the list of default values. |
900 | If non-nil, it is available for history commands, and as the value | |
901 | (or the first element of the list of default values) to return | |
902 | if the user enters the empty string. But, unless READ is non-nil, | |
903 | `read-from-minibuffer' does NOT return DEFAULT-VALUE if the user enters | |
904 | empty input! It returns the empty string. | |
a1f17501 | 905 | Seventh arg INHERIT-INPUT-METHOD, if non-nil, means the minibuffer inherits |
029a305c | 906 | the current input method and the setting of `enable-multibyte-characters'. |
a1f17501 PJ |
907 | If the variable `minibuffer-allow-text-properties' is non-nil, |
908 | then the string which is returned includes whatever text properties | |
6b61353c KH |
909 | were present in the minibuffer. Otherwise the value has no text properties. |
910 | ||
911 | The remainder of this documentation string describes the | |
912 | INITIAL-CONTENTS argument in more detail. It is only relevant when | |
913 | studying existing code, or when HIST is a cons. If non-nil, | |
914 | INITIAL-CONTENTS is a string to be inserted into the minibuffer before | |
915 | reading input. Normally, point is put at the end of that string. | |
916 | However, if INITIAL-CONTENTS is \(STRING . POSITION), the initial | |
917 | input is STRING, but point is placed at _one-indexed_ position | |
918 | POSITION in the minibuffer. Any integer value less than or equal to | |
919 | one puts point at the beginning of the string. *Note* that this | |
920 | behavior differs from the way such arguments are used in `completing-read' | |
921 | and some related functions, which use zero-indexing for POSITION. */) | |

1636 | - nil means that the user can exit with any input. | |
b47d0e56 CY |
1637 | - `confirm' means that the user can exit with any input, but she needs |
1638 | to confirm her choice if the input is not an element of COLLECTION. | |
1639 | - `confirm-after-completion' means that the user can exit with any | |
1640 | input, but she needs to confirm her choice if she called | |
1641 | `minibuffer-complete' right before `minibuffer-complete-and-exit' | |
1642 | and the input is not an element of COLLECTION. | |

1644 | does non-null completion. | |

1650 | If INITIAL-INPUT is non-nil, insert it in the minibuffer initially, | |
1651 | with point positioned at the end. | |
1652 | If it is (STRING . POSITION), the initial input is STRING, but point | |
1653 | is placed at _zero-indexed_ position POSITION in STRING. (*Note* | |
1654 | that this is different from `read-from-minibuffer' and related | |
1655 | functions, which use one-indexing for POSITION.) This feature is | |
1656 | deprecated--it is best to pass nil for INITIAL-INPUT and supply the | |
1657 | default value DEF instead. The user can yank the default value into | |
1658 | the minibuffer easily using \\[next-history-element]. | |
1659 | ||
1660 | HIST, if non-nil, specifies a history list and optionally the initial | |
1661 | position in the list. It can be a symbol, which is the history list | |
1662 | variable to use, or it can be a cons cell (HISTVAR . HISTPOS). In | |
1663 | that case, HISTVAR is the history list variable to use, and HISTPOS | |
1664 | is the initial position (the position in the list used by the | |
1665 | minibuffer history commands). For consistency, you should also | |
1666 | specify that element of the history as the value of | |
1fb101f3 | 1667 | INITIAL-INPUT. (This is the only case in which you should use |
6b61353c KH |
1668 | INITIAL-INPUT instead of DEF.) Positions are counted starting from |
1669 | 1 at the beginning of the list. The variable `history-length' | |
1670 | controls the maximum length of a history list. | |
38668f81 | 1671 | |
