943 | The optional second arg INITIAL-CONTENTS is an obsolete alternative to |
944 | DEFAULT-VALUE. It normally should be nil in new code, except when | |
945 | HIST is a cons. It is discussed in more detail below. | |
a1f17501 PJ |
946 | Third arg KEYMAP is a keymap to use whilst reading; |
947 | if omitted or nil, the default is `minibuffer-local-map'. | |
fd771ceb | 948 | If fourth arg READ is non-nil, then interpret the result as a Lisp object |
a1f17501 PJ |
949 | and return that object: |
950 | in other words, do `(car (read-from-string INPUT-STRING))' | |
6b61353c KH |
951 | Fifth arg HIST, if non-nil, specifies a history list and optionally |
952 | the initial position in the list. It can be a symbol, which is the | |
953 | history list variable to use, or it can be a cons cell | |
954 | (HISTVAR . HISTPOS). In that case, HISTVAR is the history list variable | |
955 | to use, and HISTPOS is the initial position for use by the minibuffer | |
956 | history commands. For consistency, you should also specify that | |
957 | element of the history as the value of INITIAL-CONTENTS. Positions | |
958 | are counted starting from 1 at the beginning of the list. | |
2e3148e2 JL |
959 | Sixth arg DEFAULT-VALUE is the default value or the list of default values. |
960 | If non-nil, it is available for history commands, and as the value | |
961 | (or the first element of the list of default values) to return | |
962 | if the user enters the empty string. But, unless READ is non-nil, | |
963 | `read-from-minibuffer' does NOT return DEFAULT-VALUE if the user enters | |
964 | empty input! It returns the empty string. | |
a1f17501 | 965 | Seventh arg INHERIT-INPUT-METHOD, if non-nil, means the minibuffer inherits |
029a305c | 966 | the current input method and the setting of `enable-multibyte-characters'. |
a1f17501 PJ |
967 | If the variable `minibuffer-allow-text-properties' is non-nil, |
968 | then the string which is returned includes whatever text properties | |
6b61353c KH |
969 | were present in the minibuffer. Otherwise the value has no text properties. |
970 | ||
971 | The remainder of this documentation string describes the | |
972 | INITIAL-CONTENTS argument in more detail. It is only relevant when | |
973 | studying existing code, or when HIST is a cons. If non-nil, | |
974 | INITIAL-CONTENTS is a string to be inserted into the minibuffer before | |
975 | reading input. Normally, point is put at the end of that string. | |
976 | However, if INITIAL-CONTENTS is \(STRING . POSITION), the initial | |
977 | input is STRING, but point is placed at _one-indexed_ position | |
978 | POSITION in the minibuffer. Any integer value less than or equal to | |
979 | one puts point at the beginning of the string. *Note* that this | |
980 | behavior differs from the way such arguments are used in `completing-read' | |
981 | and some related functions, which use zero-indexing for POSITION. */) | |
