Hello, Open the editor, and copy the attached code snippet : local laneFunc = function() … end require "lanes" local lane_gen = lanes.gen(laneFunc) local lane_h = lane_gen() return true Then start the debugger, step until after the lane_h
variable is assigned, and hover the mouse cursor over the lane_h variable, and the
debugger will terminate itself with «quitting debugger » in
the log. It would seem that this happens because the userdata contained in
lane_h doesn’t have a __tostring() metamethod. At least when considering this
trace from a more complex app : ...a\5.1\SciTE\scite-debug\lua_clidebugger\debugger.lua:776:
C:\Program Files\Lua\5.1\lua\lanes.lua:189: Unknown key: __tostring stack traceback: ...a\5.1\SciTE\scite-debug\lua_clidebugger\debugger.lua:1485:

lane_h_MT= getmetatable( lane_h) lane_h_MT.__tostring

problem. What can I do to fix this ? Thanks, B. Germain |
