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

: /* Read a string in the minibuffer, with completion.
1688 PROMPT is a string to prompt with; normally it ends in a colon and a space.
1689 TABLE can be a list of strings, an alist, an obarray or a hash table.
1690 TABLE can also be a function to do the completion itself.
1691 PREDICATE limits completion to a subset of TABLE.
1692 See `try-completion' and `all-completions' for more details
1693 on completion, TABLE, and PREDICATE.
1695 If REQUIRE-MATCH is non-nil, the user is not allowed to exit unless
1696 the input is (or completes to) an element of TABLE or is null.
1697 If it is also not t, typing RET does not exit if it does non-null completion.
1698 If the input is null, `completing-read' returns DEF, or an empty string
1699 if DEF is nil, regardless of the value of REQUIRE-MATCH.
1701 If INITIAL-INPUT is non-nil, insert it in the minibuffer initially,
1702 with point positioned at the end.
1703 If it is (STRING . POSITION), the initial input is STRING, but point
1704 is placed at _zero-indexed_ position POSITION in STRING. (*Note*
1705 that this is different from `read-from-minibuffer' and related
1706 functions, which use one-indexing for POSITION.) This feature is
1707 deprecated--it is best to pass nil for INITIAL-INPUT and supply the
1708 default value DEF instead. The user can yank the default value into
1709 the minibuffer easily using \\[next-history-element].
1711 HIST, if non-nil, specifies a history list and optionally the initial
1712 position in the list. It can be a symbol, which is the history list
1713 variable to use, or it can be a cons cell (HISTVAR . HISTPOS). In
1714 that case, HISTVAR is the history list variable to use, and HISTPOS
1715 is the initial position (the position in the list used by the
1716 minibuffer history commands). For consistency, you should also
1717 specify that element of the history as the value of
1718 INITIAL-INPUT. (This is the only case in which you should use
1719 INITIAL-INPUT instead of DEF.) Positions are counted starting from
1720 1 at the beginning of the list. The variable `history-length'
1721 controls the maximum length of a history list.
1723 DEF, if non-nil, is the default value.
1725 If INHERIT-INPUT-METHOD is non-nil, the minibuffer inherits
1726 the current input method and the setting of `enable-multibyte-characters'.
1728 Completion ignores case if the ambient value of
1729 `completion-ignore-case' is non-nil. */)
