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

: /* Read a string in the minibuffer, with completion.
1691 PROMPT is a string to prompt with; normally it ends in a colon and a space.
1692 TABLE can be a list of strings, an alist, an obarray or a hash table.
1693 TABLE can also be a function to do the completion itself.
1694 PREDICATE limits completion to a subset of TABLE.
1695 See `try-completion' and `all-completions' for more details
1696 on completion, TABLE, and PREDICATE.
1698 If REQUIRE-MATCH is non-nil, the user is not allowed to exit unless
1699 the input is (or completes to) an element of TABLE or is null.
1700 If it is also not t, typing RET does not exit if it does non-null completion.
1701 If the input is null, `completing-read' returns DEF, or an empty string
1702 if DEF is nil, regardless of the value of REQUIRE-MATCH.
1704 If INITIAL-INPUT is non-nil, insert it in the minibuffer initially,
1705 with point positioned at the end.
1706 If it is (STRING . POSITION), the initial input is STRING, but point
1707 is placed at _zero-indexed_ position POSITION in STRING. (*Note*
1708 that this is different from `read-from-minibuffer' and related
1709 functions, which use one-indexing for POSITION.) This feature is
1710 deprecated--it is best to pass nil for INITIAL-INPUT and supply the
1711 default value DEF instead. The user can yank the default value into
1712 the minibuffer easily using \\[next-history-element].
1714 HIST, if non-nil, specifies a history list and optionally the initial
1715 position in the list. It can be a symbol, which is the history list
1716 variable to use, or it can be a cons cell (HISTVAR . HISTPOS). In
1717 that case, HISTVAR is the history list variable to use, and HISTPOS
1718 is the initial position (the position in the list used by the
1719 minibuffer history commands). For consistency, you should also
1720 specify that element of the history as the value of
1721 INITIAL-INPUT. (This is the only case in which you should use
1722 INITIAL-INPUT instead of DEF.) Positions are counted starting from
1723 1 at the beginning of the list. The variable `history-length'
1724 controls the maximum length of a history list.
1726 DEF, if non-nil, is the default value.
1728 If INHERIT-INPUT-METHOD is non-nil, the minibuffer inherits
1729 the current input method and the setting of `enable-multibyte-characters'.
1731 Completion ignores case if the ambient value of
1732 `completion-ignore-case' is non-nil. */)
