From 9d4f2e77cc2606d031ab87426387d8687a67d90d Mon Sep 17 00:00:00 2001 From: Barrett Ruth Date: Wed, 4 Mar 2026 13:48:46 -0500 Subject: [PATCH] fix(commands): register VimLeavePre to call stop_all Problem: spawned compiler processes and watching autocmds were never cleaned up when Neovim exited, leaving orphaned processes running. Solution: register a VimLeavePre autocmd in commands setup that calls compiler.stop_all(), which kills active processes, unwatches all buffers, and stops the reload server. --- lua/preview/commands.lua | 6 ++++++ spec/commands_spec.lua | 13 +++++++++++++ 2 files changed, 19 insertions(+) diff --git a/lua/preview/commands.lua b/lua/preview/commands.lua index a2e0470..97a13f7 100644 --- a/lua/preview/commands.lua +++ b/lua/preview/commands.lua @@ -57,6 +57,12 @@ function M.setup() end, desc = 'Toggle, compile, clean, open, or check status of document preview', }) + + vim.api.nvim_create_autocmd('VimLeavePre', { + callback = function() + require('preview.compiler').stop_all() + end, + }) end return M diff --git a/spec/commands_spec.lua b/spec/commands_spec.lua index 5cca5a2..4e12e5d 100644 --- a/spec/commands_spec.lua +++ b/spec/commands_spec.lua @@ -11,6 +11,19 @@ describe('commands', function() local cmds = vim.api.nvim_get_commands({}) assert.is_not_nil(cmds.Preview) end) + + it('registers VimLeavePre autocmd', function() + require('preview.commands').setup() + local aus = vim.api.nvim_get_autocmds({ event = 'VimLeavePre' }) + local found = false + for _, au in ipairs(aus) do + if au.callback then + found = true + break + end + end + assert.is_true(found) + end) end) describe('dispatch', function()
