assertion

问题 I'm trying to customize a template for a demo of a webapp built on AngularJS using MacOS Sierra 10.13.6 . I've installed Gulp but when I launch gulp serve return this error without launching the local server: assert.js:337 throw err; ^ AssertionError [ERR_ASSERTION]: Task function must be specified at Gulp.set [as _setTask] (/Users/barkia/Desktop/Elysium/repos/elysium-webapp/material/node_modules/undertaker/lib/set-task.js:10:3) at Gulp.task (/Users/barkia/Desktop/Elysium/repos/elysium-webapp

问题 I am trying to create a log system on my program that will log debugging messages on text files, and I want to save the exact place in the code where the log message called, but I don't want to use Assert function because it creates exceptions and this system is not for logging exceptions only, also I have to write some debugging info. example usning assert: procedure AnyProcedure(); begin try Assert(1=0); except on E: Exception do Log.AddLine('Log occurred is '+E.Message+' : Start');//Log

问题 I know why assertive programming is good, so I want to use it with JavaScript. However, I don't want to show users error boxes, and it's unusual thing. Just ignore it and make them retry could be better. For example this code will make an error box and interrupt users. function getDomainFromURL(url) { assertTrue(url, 'URL should not be null'); ...parsing } So, I'd make like this. function getDomainFromURL(url) { if (!url) return; ...parsing } Second one is good for usability, I think, and

问题 We're in the process of looking into implementing SAML based SSO authentication in our applications and I'm wondering if it's possible to specify custom redirect URLs via SAML. In other words can we have a single Service Provider configured in the Identity Provider and have the Service Provider via the SAML request specify where the Identity Provider should redirect the user to after logging in? The reason why we're looking for something like this is because our applications run on different

问题 I am using assert in python. Every time an assert fails I get the failure message which I would have put there to be printed. I was wondering if there is a way to print a custom success message when the assert condition passes? I am using py.test framework. for instance: assert self.clnt.stop_io()==1, "IO stop failed" for the above assert I get message "IO stop failed" if assert fails but I am looking to have "IO stop succeeded" if assert passes. something like this: assert self.clnt.stop_io(

问题 What is the equivalent technique of an assertion in CUDA kernel code? There does not seem to be an assert for CUDA kernel code. I want a way to catch programmer mistakes easily in kernel code. A mechanism where I can set conditions that need to be true and the kernel should bail out when the condition is false with an error message. 回答1: You won't be able to return an error message or error code to the host from a kernel. Instead, I would set a error state and check it from the host. Use

问题 I have just came across this piece of code on this blog post type Logger interface { Debug(msg string, keyvals ...interface{}) error Info(msg string, keyvals ...interface{}) error Error(msg string, keyvals ...interface{}) error } type tmLogger struct { srcLogger kitlog.Logger } // Interface assertions var _ Logger = (*tmLogger)(nil) // What is this? // ... interface definition ... What is this "interface assertion"? 回答1: It assigns a nil pointer to a concrete type to a variable of the

问题 I can't gracefully get pixels of an image as array in general case. f, err := os.Open(imgPath) check(err) defer f.Close() img, _, err := image.Decode(bufio.NewReader(f)) check(err) pixels, err := getPixels(img) check(err) // Logic with pixels. Now function getPixels looks like this: func getPixels(img image.Image) ([]uint8, error) { if i, ok := img.(*image.NRGBA); ok { return i.Pix, nil } else if i, ok := img.(*image.Alpha); ok { return i.Pix, nil } else if i, ok := img.(*image.Alpha16); ok {
