975 | The optional second arg INITIAL-CONTENTS is an obsolete alternative to |
976 | DEFAULT-VALUE. It normally should be nil in new code, except when | |
977 | HIST is a cons. It is discussed in more detail below. | |
a1f17501 PJ |
978 | Third arg KEYMAP is a keymap to use whilst reading; |
979 | if omitted or nil, the default is `minibuffer-local-map'. | |
fd771ceb | 980 | If fourth arg READ is non-nil, then interpret the result as a Lisp object |
a1f17501 PJ |
981 | and return that object: |
982 | in other words, do `(car (read-from-string INPUT-STRING))' | |
b0c138ce LT |
983 | Fifth arg HIST, if non-nil, specifies a history list and optionally |
984 | the initial position in the list. It can be a symbol, which is the | |
985 | history list variable to use, or it can be a cons cell | |
986 | (HISTVAR . HISTPOS). In that case, HISTVAR is the history list variable | |
987 | to use, and HISTPOS is the initial position for use by the minibuffer | |
988 | history commands. For consistency, you should also specify that | |
989 | element of the history as the value of INITIAL-CONTENTS. Positions | |
990 | are counted starting from 1 at the beginning of the list. | |
a1f17501 | 991 | Sixth arg DEFAULT-VALUE is the default value. If non-nil, it is available |
adb0708c LT |
992 | for history commands; but, unless READ is non-nil, `read-from-minibuffer' |
993 | does NOT return DEFAULT-VALUE if the user enters empty input! It returns | |
994 | the empty string. | |
a1f17501 | 995 | Seventh arg INHERIT-INPUT-METHOD, if non-nil, means the minibuffer inherits |
029a305c | 996 | the current input method and the setting of `enable-multibyte-characters'. |
a1f17501 PJ |
997 | If the variable `minibuffer-allow-text-properties' is non-nil, |
998 | then the string which is returned includes whatever text properties | |
b0c138ce LT |
999 | were present in the minibuffer. Otherwise the value has no text properties. |
1000 | ||
1001 | The remainder of this documentation string describes the | |
1002 | INITIAL-CONTENTS argument in more detail. It is only relevant when | |
1003 | studying existing code, or when HIST is a cons. If non-nil, | |
1004 | INITIAL-CONTENTS is a string to be inserted into the minibuffer before | |
1005 | reading input. Normally, point is put at the end of that string. | |
1006 | However, if INITIAL-CONTENTS is \(STRING . POSITION), the initial | |
1007 | input is STRING, but point is placed at _one-indexed_ position | |
1008 | POSITION in the minibuffer. Any integer value less than or equal to | |
1009 | one puts point at the beginning of the string. *Note* that this | |
1010 | behavior differs from the way such arguments are used in `completing-read' | |
1011 | and some related functions, which use zero-indexing for POSITION. */) | |
