927 | The optional second arg INITIAL-CONTENTS is an obsolete alternative to |
928 | DEFAULT-VALUE. It normally should be nil in new code, except when | |
929 | HIST is a cons. It is discussed in more detail below. | |
a1f17501 PJ |
930 | Third arg KEYMAP is a keymap to use whilst reading; |
931 | if omitted or nil, the default is `minibuffer-local-map'. | |
fd771ceb | 932 | If fourth arg READ is non-nil, then interpret the result as a Lisp object |
a1f17501 PJ |
933 | and return that object: |
934 | in other words, do `(car (read-from-string INPUT-STRING))' | |
b0c138ce LT |
935 | Fifth arg HIST, if non-nil, specifies a history list and optionally |
936 | the initial position in the list. It can be a symbol, which is the | |
937 | history list variable to use, or it can be a cons cell | |
938 | (HISTVAR . HISTPOS). In that case, HISTVAR is the history list variable | |
939 | to use, and HISTPOS is the initial position for use by the minibuffer | |
940 | history commands. For consistency, you should also specify that | |
941 | element of the history as the value of INITIAL-CONTENTS. Positions | |
942 | are counted starting from 1 at the beginning of the list. | |
a1f17501 | 943 | Sixth arg DEFAULT-VALUE is the default value. If non-nil, it is available |
adb0708c LT |
944 | for history commands; but, unless READ is non-nil, `read-from-minibuffer' |
945 | does NOT return DEFAULT-VALUE if the user enters empty input! It returns | |
946 | the empty string. | |
a1f17501 | 947 | Seventh arg INHERIT-INPUT-METHOD, if non-nil, means the minibuffer inherits |
029a305c | 948 | the current input method and the setting of `enable-multibyte-characters'. |
da34f64e RS |
949 | Eight arg KEEP-ALL, if non-nil, says to put all inputs in the history list, |
950 | even empty or duplicate inputs. | |
a1f17501 PJ |
951 | If the variable `minibuffer-allow-text-properties' is non-nil, |
952 | then the string which is returned includes whatever text properties | |
b0c138ce LT |
953 | were present in the minibuffer. Otherwise the value has no text properties. |
954 | ||
955 | The remainder of this documentation string describes the | |
956 | INITIAL-CONTENTS argument in more detail. It is only relevant when | |
957 | studying existing code, or when HIST is a cons. If non-nil, | |
958 | INITIAL-CONTENTS is a string to be inserted into the minibuffer before | |
959 | reading input. Normally, point is put at the end of that string. | |
960 | However, if INITIAL-CONTENTS is \(STRING . POSITION), the initial | |
961 | input is STRING, but point is placed at _one-indexed_ position | |
962 | POSITION in the minibuffer. Any integer value less than or equal to | |
963 | one puts point at the beginning of the string. *Note* that this | |
964 | behavior differs from the way such arguments are used in `completing-read' | |
965 | and some related functions, which use zero-indexing for POSITION. */) | |

1679 | If it is (STRING . POSITION), the initial input is STRING, but point | |
1680 | is placed at _zero-indexed_ position POSITION in STRING. (*Note* | |
1681 | that this is different from `read-from-minibuffer' and related | |
1682 | functions, which use one-indexing for POSITION.) This feature is | |
1683 | deprecated--it is best to pass nil for INITIAL-INPUT and supply the | |

1690 | that case, HISTVAR is the history list variable to use, and HISTPOS | |
1691 | is the initial position (the position in the list used by the | |
1692 | minibuffer history commands). For consistency, you should also | |
1693 | specify that element of the history as the value of | |
1fb101f3 | 1694 | INITIAL-INPUT. (This is the only case in which you should use |
b0c138ce LT |
1695 | INITIAL-INPUT instead of DEF.) Positions are counted starting from |
1696 | 1 at the beginning of the list. The variable `history-length' | |
