911 | The optional second arg INITIAL-CONTENTS is an obsolete alternative to |
912 | DEFAULT-VALUE. It normally should be nil in new code, except when | |
913 | HIST is a cons. It is discussed in more detail below. | |
a1f17501 PJ |
914 | Third arg KEYMAP is a keymap to use whilst reading; |
915 | if omitted or nil, the default is `minibuffer-local-map'. | |
fd771ceb | 916 | If fourth arg READ is non-nil, then interpret the result as a Lisp object |
a1f17501 PJ |
917 | and return that object: |
918 | in other words, do `(car (read-from-string INPUT-STRING))' | |
b0c138ce LT |
919 | Fifth arg HIST, if non-nil, specifies a history list and optionally |
920 | the initial position in the list. It can be a symbol, which is the | |
921 | history list variable to use, or it can be a cons cell | |
922 | (HISTVAR . HISTPOS). In that case, HISTVAR is the history list variable | |
923 | to use, and HISTPOS is the initial position for use by the minibuffer | |
924 | history commands. For consistency, you should also specify that | |
925 | element of the history as the value of INITIAL-CONTENTS. Positions | |
926 | are counted starting from 1 at the beginning of the list. | |
a1f17501 | 927 | Sixth arg DEFAULT-VALUE is the default value. If non-nil, it is available |
adb0708c LT |
928 | for history commands; but, unless READ is non-nil, `read-from-minibuffer' |
929 | does NOT return DEFAULT-VALUE if the user enters empty input! It returns | |
930 | the empty string. | |
a1f17501 | 931 | Seventh arg INHERIT-INPUT-METHOD, if non-nil, means the minibuffer inherits |
029a305c | 932 | the current input method and the setting of `enable-multibyte-characters'. |
a1f17501 PJ |
933 | If the variable `minibuffer-allow-text-properties' is non-nil, |
934 | then the string which is returned includes whatever text properties | |
b0c138ce LT |
935 | were present in the minibuffer. Otherwise the value has no text properties. |
936 | ||
937 | The remainder of this documentation string describes the | |
938 | INITIAL-CONTENTS argument in more detail. It is only relevant when | |
939 | studying existing code, or when HIST is a cons. If non-nil, | |
940 | INITIAL-CONTENTS is a string to be inserted into the minibuffer before | |
941 | reading input. Normally, point is put at the end of that string. | |
942 | However, if INITIAL-CONTENTS is \(STRING . POSITION), the initial | |
943 | input is STRING, but point is placed at _one-indexed_ position | |
944 | POSITION in the minibuffer. Any integer value less than or equal to | |
945 | one puts point at the beginning of the string. *Note* that this | |
946 | behavior differs from the way such arguments are used in `completing-read' | |
947 | and some related functions, which use zero-indexing for POSITION. */) | |

1616 | on completion, TABLE, and PREDICATE. | |

1624 | If INITIAL-INPUT is non-nil, insert it in the minibuffer initially, | |
1625 | with point positioned at the end. | |
1626 | If it is (STRING . POSITION), the initial input is STRING, but point | |
1627 | is placed at _zero-indexed_ position POSITION in STRING. (*Note* | |
1628 | that this is different from `read-from-minibuffer' and related | |
1629 | functions, which use one-indexing for POSITION.) This feature is | |
1630 | deprecated--it is best to pass nil for INITIAL-INPUT and supply the | |
1631 | default value DEF instead. The user can yank the default value into | |
1632 | the minibuffer easily using \\[next-history-element]. | |

1634 | HIST, if non-nil, specifies a history list and optionally the initial | |

1637 | that case, HISTVAR is the history list variable to use, and HISTPOS | |
1638 | is the initial position (the position in the list used by the | |
1639 | minibuffer history commands). For consistency, you should also | |
1640 | specify that element of the history as the value of | |
1fb101f3 | 1641 | INITIAL-INPUT. (This is the only case in which you should use |
b0c138ce LT |
1642 | INITIAL-INPUT instead of DEF.) Positions are counted starting from |
1643 | 1 at the beginning of the list. The variable `history-length' | |

2692 | CODE, which says what kind of things to do. | |
2693 | CODE can be nil, t or `lambda'. | |
2694 | nil means to return the best completion of STRING, or nil if there is none. | |
