    I try to use pcall(function()end) and assertion(fucntion() end) in lua code, but program still crashed.
    my question is how to catch exception in app ,if has I catch error,app can still work,not print stack trace on console and app crashed.

      I think you need to give more information. For example here is a simple example code snippet:
      local function crash()
	a[1] = 10
end
 
local status, err = pcall(crash)
 
print(status, err)
      btw, does your program crash or give lua error?

      sorry ,my fault.
      local function crash()
	assert(nil,"crash error")
end
 
local status, err = pcall(crash)
 
print(status, err)

      @louis,
      I think the whole idea of assert is to crash if the condition was not met, assert cannot be masked even if used with pcall.
