+ ==============================================================================
+ 1. Introduction *popup-intro*
+
+ We are talking about popup windows here, text that goes on top of the buffer
+ text and is under control of a plugin. Other popup functionality:
+ - popup menu, see |popup-menu|
+ - balloon, see |balloon-eval|
+

+ 2. Functions *popup-functions*
+
+ THIS IS UNDER DESIGN - ANYTHING MAY STILL CHANGE
+
+ Proposal and discussion on issue #4063: https://github.com/vim/vim/issues/4063
+
+ [to be moved to eval.txt later]
+
+ popup_show({lines}, {options}) *popup_show()*
+ Open a popup window showing {lines}, which is a list of lines,
+ where each line has text and text properties.
+
+ {options} is a dictionary with many possible entries.
+
+ Returns a unique ID to be used with |popup_close()|.
+
+ See |popup_show-usage| for details.
+
+
+ popup_dialog({lines}, {options}) *popup_dialog()*
+ Just like |popup_show()| but with different default options:
+ pos "center"
+ zindex 200
+ border []
+
+
+ popup_notification({text}, {options}) *popup_notification()*
+ Show the string {text} for 3 seconds at the top of the Vim
+ window. This works like: >
+ call popup_show([{'text': {text}}], {
+ \ 'line': 1,
+ \ 'col': 10,
+ \ 'time': 3000,
+ \ 'zindex': 200,
+ \ 'highlight': 'WarningMsg',
+ \ 'border: [],
+ \ })
+ < Use {options} to change the properties.
+
+ popup_atcursor({text}, {options}) *popup_atcursor()*
+ Show the string {text} above the cursor, and close it when the
+ cursor moves. This works like: >
+ call popup_show([{'text': {text}}], {
+ \ 'line': 'cursor-1',
+ \ 'col': 'cursor',
+ \ 'zindex': 50,
+ \ 'moved': 'WORD',
+ \ })
+ < Use {options} to change the properties.
+
+
+ popup_menu({lines}, {options}) *popup_atcursor()*
+ Show the {lines} near the cursor, handle selecting one of the
+ items with cursorkeys, and close it an item is selected with
+ Space or Enter. This works like: >
+ call popup_show({lines}, {
+ \ 'pos': 'center',
+ \ 'zindex': 200,
+ \ 'wrap': 0,
+ \ 'border': [],
+ \ 'filter': 'popup_filter_menu',
+ \ })
+ < Use {options} to change the properties. Should at least set
+ "callback" to a function that handles the selected item.
+
+
+ popup_move({id}, {options}) *popup_move()*
+ Move popup {id} to the position speficied with {options}.
+ {options} may contain the items from |popup_show()| that
+ specify the popup position: "line", "col", "pos", "maxheight",
+ "minheight", "maxwidth" and "minwidth".
+
+
+ popup_filter_menu({id}, {key})
*popup_filter_menu()*
+ Filter that can be used for a popup. It handles the cursor
+ keys to move the selected index in the popup. Space and Enter
+ can be used to select an item. Invokes the "callback" of the
+ popup menu with the index of the selected line as the second
+ argument.
+
+
+ popup_filter_yesno({id}, {key})
*popup_filter_yesno()*
+ Filter that can be used for a popup. It handles only the keys
+ 'y', 'Y' and 'n' or 'N'. Invokes the "callback" of the
+ popup menu with the 1 for 'y' or 'Y' and zero for 'n' or 'N'
+ as the second argument. Pressing Esc and CTRL-C works like
+ pressing 'n'.
+
+
+ popup_setlines({id}, {lnum}, {lines}) *popup_setlines()*
+ In popup {id} set line {lnum} and following to {lines}.
+
+ {lnum} is one-based and must be either an existing line or
+ just one below the last line, in which case the line gets
+ appended.
+
+ {lines} has the same format as one item in {lines} of
+ |popup_show()|. Existing lines are replaced. When {lines}
+ extends below the last line of the popup lines are appended.
+
+ popup_getlines({id}) *popup_getlines()*
+ Return the {lines} for popup {id}.
+
+
+ popup_setoptions({id}, {options}) *popup_setoptions()*
+ Override options in popup {id} with entries in {options}.
+
+
+ popup_getoptions({id})
*popup_getoptions()*
+ Return the {options} for popup {id}.
+
+
+ popup_close({id}) *popup_close()*
+ Close popup {id}.
+
+
+ POPUP_SHOW() ARGUMENTS
*popup_show-usage*
+
+ The first argument of |popup_show()| is a list of text lines. Each item in
+ the list is a dictionary with these entries:
+ text The text to display.
+ props A list of text properties. Optional.
+ Each entry is a dictionary, like the third argument of
+ |prop_add()|, but specifying the column in the
+ dictionary with a "col" entry, see below:
+ |popup-props|.
+
+ The second argument of |popup_show()| is a dictionary with options:
+ line screen line where to position the popup; can use
+ "cursor", "cursor+1" or "cursor-1" to use the line of
+ the cursor and add or subtract a number of lines;
+ default is "cursor-1".
+ col screen column where to position the popup; can use
+ "cursor" to use the column of the cursor, "cursor+99"
+ and "cursor-99" to add or subtract a number of
+ columns; default is "cursor"
+ pos "topleft", "topright", "botleft" or "botright":
+ defines what corner of the popup "line" and "col" are
+ used for. Default is "botleft". Alternatively
+ "center" can be used to position the popup somewhere
+ near the cursor.
+ maxheight maximum height
+ minheight minimum height
+ maxwidth maximum width
+ minwidth minimum width
+ title text to be displayed above the first item in the
+ popup, on top of any border
+ wrap TRUE to make the lines wrap (default TRUE)
+ highlight highlight group name to use for the text, defines the
+ background and foreground color
+ border list with numbers, defining the border thickness
+ above/right/below/left of the popup; an empty list
+ uses a border of 1 all around
+ borderhighlight highlight group name to use for the border
+ borderchars list with characters, defining the character to use
+ for the top/right/bottom/left border; optionally
+ followed by the character to use for the
+ topright/botright/botleft/topleft corner; an empty
+ list can be used to show a double line all around
+ zindex priority for the popup, default 50
+ time time in milliseconds after which the popup will close;
+ when omitted |popup_close()| must be used.
+ moved "cell": close the popup if the cursor moved at least
+ one screen cell; "word" allows for moving within
+ |<cword>|, "WORD" allows for moving within |<cWORD>|,
+ a list with two numbers specifies the start and end
+ column
+ filter a callback that can filter typed characters, see
+ |popup-filter|
+ callback a callback to be used when the popup closes, e.g. when
+ using |popup_filter_menu()|, see |popup-callback|.
+
+ Depending on the "zindex" the popup goes under or above other popups. The
+ completion menu (|popup-menu|) has zindex 100. For messages that occur for a
+ short time the suggestion is to use zindex 1000.
+
+ By default text wraps, which causes a line in {lines} to occupy more than one
+ screen line. When "wrap" is FALSE then the text outside of the popup or
+ outside of the Vim window will not be displayed, thus truncated.
+
+
+ POPUP TEXT PROPERTIES *popup-props*
+
+ These are similar to the third argument of |prop_add()|, but not exactly the
+ same, since they only apply to one line.
+ col starting column, counted in bytes, use one for the
+ first column.
+ length length of text in bytes; can be zero
+ end_col column just after the text; not used when "length" is
+ present; when {col} and "end_col" are equal, this is a
+ zero-width text property
+ id user defined ID for the property; when omitted zero is
+ used
+ type name of the text property type, as added with
+ |prop_type_add()|
+ transparent do not show these characters, show the text under it;
+ if there is an border character to the right or below
+ it will be made transparent as well
+
+
+ POPUP FILTER *popup-filter*
+
+ A callback that gets any typed keys while a popup is displayed. It can return
+ TRUE to indicate the key has been handled and is to be discarded, or FALSE to
+ let Vim handle the key as usual in the current state.
+
+ The filter function is called with two arguments: the ID of the popup and the
+ key.
+
+ Some common key actions:
+ Esc close the popup
+ cursor keys select another entry
+ Tab accept current suggestion
+
+ Vim provides standard filters |popup_filter_menu()| and
+ |popup_filter_yesno()|.
+
+
+ POPUP CALLBACK *popup-callback*
+
+ A callback that is invoked when the popup closes. Used by
+ |popup_filter_menu()|. Invoked with two arguments: the ID of the popup and
+ the result, which would usually be an index in the popup lines, or whatever
+ the filter wants to pass.
+
+ ==============================================================================
+ 3. Examples *popup-examples*
+
+ TODO
+
+ Prompt the user to press y/Y or n/N: >
+
+ func MyDialogHandler(id, result)
+ if a:result
+ " ... 'y' or 'Y' was pressed
+ endif
+ endfunc
+
+ call popup_show([{'text': 'Continue? y/n'}], {
+ \ 'filter': 'popup_filter_yesno',
+ \ 'callback': 'MyDialogHandler',
+ \ })
