From d44ed79ccc43b59fec9ef622f18f543ef1c73263 Mon Sep 17 00:00:00 2001 From: "Justin M. Keyes" Date: Sun, 17 Jun 2018 23:05:28 +0200 Subject: [PATCH] startup: go to buffer 2 if stdin is empty If stdin is not a TTY we read it into buffer 1, as text. But if the stdin pipe is empty, Nvim was most likely invoked for some other reason. DWIM: select buffer 2 (if it exists). Example: echo file1 | xargs nvim closes #8560 closes #8561 ref https://github.com/equalsraf/neovim-qt/issues/417 --- src/nvim/main.c | 6 ++++++ test/functional/core/startup_spec.lua | 12 ++++++++++++ 2 files changed, 18 insertions(+) diff --git a/src/nvim/main.c b/src/nvim/main.c index ea43b93b30..9c9be4aa02 100644 --- a/src/nvim/main.c +++ b/src/nvim/main.c @@ -1410,6 +1410,12 @@ static void read_stdin(void) int save_msg_didany = msg_didany; set_buflisted(true); (void)open_buffer(true, NULL, 0); // create memfile and read file + if (BUFEMPTY() && curbuf->b_next != NULL) { + // stdin was empty, go to buffer 2 (e.g. "echo file1 | xargs nvim"). #8561 + msg_silent++; + do_buffer(DOBUF_GOTO, DOBUF_FIRST, FORWARD, curbuf->b_next->handle, 0); + msg_silent--; + } no_wait_return = false; msg_didany = save_msg_didany; TIME_MSG("reading stdin"); diff --git a/test/functional/core/startup_spec.lua b/test/functional/core/startup_spec.lua index ae5e2b4115..5f18b902fb 100644 --- a/test/functional/core/startup_spec.lua +++ b/test/functional/core/startup_spec.lua @@ -122,6 +122,18 @@ describe('startup', function() { 'ohyeah', '' })) end) + it('goes to buffer 2 if stdin is empty #8561', function() + eq('\r\n 1u# "[No Name]" line 1\r\n 2 %a "file1" line 0\r\n 3 "file2" line 0', + funcs.system({nvim_prog, '-n', '-u', 'NONE', '-i', 'NONE', '--headless', + '+ls!', + '+qall!', + '-', + 'file1', + 'file2', + }, + { '' })) + end) + it('-e/-E interactive #7679', function() clear('-e') local screen = Screen.new(25, 3)
