From 5c2ba124ba8706f9e9a877c78e78b21c6d2874d5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc=20Andr=C3=A9=20Tanner?= Date: Sun, 22 May 2016 11:50:48 +0200 Subject: vis-lua: do not report errors recursively Displaying an error might create a new window which in turn can trigger new events (all other windows are resized+redrawn) which might again cause errors. There is still no sane way to exit the editor in this case, but at least the error messages should be readable. --- vis-lua.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'vis-lua.c') diff --git a/vis-lua.c b/vis-lua.c index fdc4fd2..eb54576 100644 --- a/vis-lua.c +++ b/vis-lua.c @@ -135,12 +135,16 @@ static void stack_dump(lua_State *L, const char *format, ...) { static int error_function(lua_State *L) { Vis *vis = lua_touserdata(L, lua_upvalueindex(1)); + if (vis->errorhandler) + return 1; + vis->errorhandler = true; size_t len; const char *msg = lua_tostring(L, 1); if (msg) luaL_traceback(L, L, msg, 1); msg = lua_tolstring(L, 1, &len); vis_message_show(vis, msg); + vis->errorhandler = false; return 1; } -- cgit v1.2.3
