["msg_show", kind, content, replace_last]
Display a message to the user.
`kind` will be one of the following
`emsg`: Internal error message
`echo`: temporary message from plugin (|:echo|)
`echomsg`: ordinary message from plugin (|:echomsg|)
`echoerr`: error message from plugin (|:echoerr|)
`return_prompt`: |press-enter| prompt after a group of messages
`quickfix`: Quickfix navigation message
`kind` can also be the empty string. The message is then some internal
informative or warning message, that hasn't yet been assigned a kind.
New message kinds can be added in later versions; clients should
handle messages of an unknown kind just like empty kind.
kind
Name indicating the message kind:
"" (empty) Unknown, report a |feature-request|
"confirm" |confirm()| or |:confirm| dialog
"confirm_sub" |:substitute| confirm dialog |:s_c|
"emsg" Error (|errors|, internal error, |:throw|, …)
"echo" |:echo| message
"echomsg" |:echomsg| message
"echoerr" |:echoerr| message
"return_prompt" |press-enter| prompt after a multiple messages
"quickfix" Quickfix navigation message
"wmsg" Warning ("search hit BOTTOM", |W10|, …)
New kinds may be added in the future; clients should treat unknown
kinds as the empty kind.
`content` will be an array of `[attr_id, text_chunk]` tuples,
building up the message text of chunks of different highlights.
No extra spacing should be added between chunks, the `text_chunk` by
itself should contain any necessary whitespace. Messages can contain
line breaks `"\n"`.
content
Array of `[attr_id, text_chunk]` tuples, building up the message
text of chunks of different highlights. No extra spacing should be
added between chunks, the `text_chunk` by itself contains any
necessary whitespace. Messages can contain line breaks "\n".
`replace_last` controls how multiple messages should be displayed.
If `replace_last` is false, this message should be displayed together
with all previous messages that are still visible. If `replace_last`
is true, this message should replace the message in the most recent
`msg_show` call, but any other visible message should still remain.
replace_last
Decides how multiple messages should be displayed:
false: Display the message together with all previous messages
that are still visible.
true: Replace the message in the most-recent `msg_show` call,
but any other visible message should still remain.
["msg_clear"]
Clear all messages currently displayed by "msg_show". (Messages sent
