From b1f25ea18797101f423cab23ac52c4e17377c5d4 Mon Sep 17 00:00:00 2001 From: "Justin M. Keyes" Date: Wed, 13 Mar 2019 22:31:07 +0100 Subject: autocmd: do not show empty section after ++once handlers expire Problem: If autocmd pattern only contained `++once` handlers, and all of them completed, then there would be an empty group displayed by `:autocmd Foo`. Solution: Delete the pattern if all of its commands were deleted. --- test/functional/autocmd/autocmd_spec.lua | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'test/functional') diff --git a/test/functional/autocmd/autocmd_spec.lua b/test/functional/autocmd/autocmd_spec.lua index f666f9cf75..814624d8e2 100644 --- a/test/functional/autocmd/autocmd_spec.lua +++ b/test/functional/autocmd/autocmd_spec.lua @@ -125,5 +125,23 @@ describe('autocmd', function() command("put ='foo bar baz'") feed('0llhlh') eq(expected, eval('g:foo')) + + -- + -- :autocmd should not show empty section after ++once handlers expire. + -- + expected = { + 'Once1', + 'Once2', + } + command('let g:foo = []') + command('autocmd!
