905 | The optional second arg INITIAL-CONTENTS is an obsolete alternative to |
906 | DEFAULT-VALUE. It normally should be nil in new code, except when | |
907 | HIST is a cons. It is discussed in more detail below. | |
f6fc4d87 | 908 | |
a1f17501 PJ |
909 | Third arg KEYMAP is a keymap to use whilst reading; |
910 | if omitted or nil, the default is `minibuffer-local-map'. | |
f6fc4d87 CY |
911 | |
912 | If fourth arg READ is non-nil, interpret the result as a Lisp object | |
a1f17501 PJ |
913 | and return that object: |
914 | in other words, do `(car (read-from-string INPUT-STRING))' | |
f6fc4d87 | 915 | |
6b61353c KH |
916 | Fifth arg HIST, if non-nil, specifies a history list and optionally |
917 | the initial position in the list. It can be a symbol, which is the | |
f6fc4d87 CY |
918 | history list variable to use, or a cons cell (HISTVAR . HISTPOS). |
919 | In that case, HISTVAR is the history list variable to use, and | |
920 | HISTPOS is the initial position for use by the minibuffer history | |
921 | commands. For consistency, you should also specify that element of | |
922 | the history as the value of INITIAL-CONTENTS. Positions are counted | |
923 | starting from 1 at the beginning of the list. | |
924 | ||
925 | Sixth arg DEFAULT-VALUE, if non-nil, should be a string, which is used | |
926 | as the default to `read' if READ is non-nil and the user enters | |
927 | empty input. But if READ is nil, this function does _not_ return | |
928 | DEFAULT-VALUE for empty input! Instead, it returns the empty string. | |
929 | ||
930 | Whatever the value of READ, DEFAULT-VALUE is made available via the | |
931 | minibuffer history commands. DEFAULT-VALUE can also be a list of | |
932 | strings, in which case all the strings are available in the history, | |
933 | and the first string is the default to `read' if READ is non-nil. | |
934 | ||
a1f17501 | 935 | Seventh arg INHERIT-INPUT-METHOD, if non-nil, means the minibuffer inherits |
029a305c | 936 | the current input method and the setting of `enable-multibyte-characters'. |
f6fc4d87 | 937 | |
a1f17501 PJ |
938 | If the variable `minibuffer-allow-text-properties' is non-nil, |
939 | then the string which is returned includes whatever text properties | |
6b61353c KH |
940 | were present in the minibuffer. Otherwise the value has no text properties. |
941 | ||
942 | The remainder of this documentation string describes the | |
943 | INITIAL-CONTENTS argument in more detail. It is only relevant when | |
944 | studying existing code, or when HIST is a cons. If non-nil, | |
945 | INITIAL-CONTENTS is a string to be inserted into the minibuffer before | |
946 | reading input. Normally, point is put at the end of that string. | |
947 | However, if INITIAL-CONTENTS is \(STRING . POSITION), the initial | |
948 | input is STRING, but point is placed at _one-indexed_ position | |
949 | POSITION in the minibuffer. Any integer value less than or equal to | |
950 | one puts point at the beginning of the string. *Note* that this | |
951 | behavior differs from the way such arguments are used in `completing-read' | |
952 | and some related functions, which use zero-indexing for POSITION. */) | |
