callback is removed.  This has only
		effect if {buf} has 'buftype' set to "prompt".

		The callback is invoked when pressing Enter.  The current
		buffer will always be the prompt buffer.  A new line for a
		prompt is added before invoking the callback, thus the prompt
		for which the callback was invoked will be in the last but one
		line.
		If the callback wants to add text to the buffer, it must
		insert it above the last line, since that is where the current
		prompt is.  This can also be done asynchronously.
		The callback is invoked with one argument, which is the text
		that was entered at the prompt.  This can be an empty string
		if the user only typed Enter.
		Example: >vim
		   func s:TextEntered(text)
		     if a:text == 'exit' || a:text == 'quit'
		       stopinsert
		       " Reset 'modified' to allow the buffer to be closed.
		       " We assume there is nothing useful to be saved.
		       set nomodified
		       close
		     else
		       " Do something useful with "a:text".  In this example
		       " we just repeat it.
		       call append(line('$') - 1, 'Entered: "' .. a:text .. '"')
		     endif
		   endfunc
		   call prompt_setcallback(bufnr(), function('s:TextEntered'))

                Parameters: ~
                  • {buf} (`integer|string`)
                  • {expr} (`string|function`)

                Return: ~
                  (`any`)

prompt_setinterrupt({buf}, {expr})                       *prompt_setinterrupt()*
		Set a callback for buffer {buf} to {expr}.  When {expr} is an
		empty string the callback is removed.  This has only effect if
		{buf} has 'buftype' set to "prompt".

		This callback will be invoked when pressing CTRL-C in Insert
		mode.  Without setting a callback Vim will exit Insert mode,
		as in any buffer.

                Parameters: ~
                  • {buf} (`integer|string`)
                  • {expr} (`string|function`)

                Return: ~
                  (`any`)

prompt_setprompt({buf}, {text})                             *prompt_setprompt()*
		Set prompt for buffer {buf} to {text}.  You most likely want
		{text} to end in a space.
		The result is only visible if {buf} has 'buftype' set to
		"prompt".  Example: >vim
			call prompt_setprompt(bufnr(''), 'command: ')
<

                Parameters: ~
                  • {buf} (`integer|string`)
                  • {text} (`string`)

                Return: ~
                  (`any`)

pum_getpos()                                                      *pum_getpos()*
		If the popup menu (see |ins-completion-menu|) is not visible,
		returns an empty |Dictionary|, otherwise, returns a
		|Dictionary| with the following keys:
			height		nr of items visible
			width		screen cells
			row		top screen row (0 first row)
			col		leftmost screen column (0 first col)
			size		total nr of items
			scrollbar	|TRUE| if scrollbar is visible

		The values are the same as in |v:event| during |CompleteChanged|.

                Return: ~
                  (`any`)

pumvisible()                                                      *pumvisible()*
		Returns non-zero when the popup menu is visible, zero
		otherwise.  See |ins-completion-menu|.
		This can be used to avoid some things that would remove the
		popup menu.

                Return: ~
                  (`any`)

py3eval({expr})                                                      *py3eval()*
		Evaluate Python expression {expr} and return its result
		converted to Vim data structures.
		Numbers and strings are returned as they are (strings are
		copied though, Unicode strings are additionally converted to
		UTF-8).
		Lists are represented as Vim |List| type.
		Dictionaries are represented as Vim |Dictionary| type with
		keys converted to strings.

                Parameters: ~
                  • {expr} (`any`)

                Return: ~
                  (`any`)

pyeval({expr})                                              *pyeval()* *E858* *E859*
		Evaluate Python expression {expr}
