"******************************************************************************
|
|
"* PURPOSE:
|
|
" An active 'showmode' setting may prevent the user from seeing the message in
|
|
" a command line. Thus, we temporarily disable the 'showmode' setting.
|
|
" Sometimes, this only happens in a single-line command line, but :echo'd text
|
|
" is visible when 'cmdline' is larger than 1. For that, use
|
|
" ingo#cmdline#showmode#OneLineTemporaryNoShowMode().
|
|
"* ASSUMPTIONS / PRECONDITIONS:
|
|
" None.
|
|
"* EFFECTS / POSTCONDITIONS:
|
|
" None.
|
|
"* INPUTS:
|
|
" None.
|
|
"* RETURN VALUES:
|
|
" Boolean flag whether the temporary mode has been activated.
