Most of the times, validation attributes are use inside frameworks (such as ASP.NET). Those frameworks take care of executing the validation attributes. But what if you want to execute validation attributes manually? Just use the Validator class (no reflection needed). Validation Context Any valid...

This example requires MdDialogRef and MD_DIALOG_DATA. Please import them in the component module. import {MdDialog, MdDialogRef, MD_DIALOG_DATA} from '@angular/material'; input-overview-example.html: <md-input-container> <input mdInput [(ngModel)]="id" ...

There are benefits to switching the root view controller, although the transition options are limited to those supported by UIViewAnimationOptions, so depending on how you wish to transition between flows might mean you have to implement a custom transition - which can be cumbersome. You can show t...

So the most used functions on Clojure map and filter have been modified to return transducers (composable algorithmic transformations), if not called with a collection. That means: (map inc) returns a transducer and so does (filter odd?) The advantage: the functions can be composed into a single f...

Here, we have created a user-defined exception called CustomError which is derived from the Exception class. This new exception can be raised, like other exceptions, using the raise statement with an optional error message. class CustomError(Exception): pass x = 1 if x == 1: rais...

This example shows how to catch custom Exception class CustomError(Exception): pass try: raise CustomError('Can you catch me ?') except CustomError as e: print ('Catched CustomError :{}'.format(e)) except Exception as e: print ('Generic exception: {}'.format(e)) Output:...

In this example, function will return as soon as value var has 1 def func(params): for value in params: print ('Got value {}'.format(value)) if value == 1: # Returns from function as soon as value is 1 print (">>>> Got 1") ...

This is a compact guide about how to quickly create an R package from your code. Exhaustive documentations will be linked when available and should be read if you want a deeper knowledge of the situation. See Remarks for more resources. The directory where your code stands will be refered as ./, an...

The possibilities are endless. as you can use this concept to pull the version number from your build system; such as git and use that version number in your project. CMakeLists.txt cmake_minimum_required(VERSION 3.8) project(project_name VERSION "0.0.0") configure_file(${path to con...

From the Terminal command line Get the current URL from Safari osascript -e 'tell app "safari" to get the url of the current tab of window 1' Get the active URL in Google Chrome osascript -e 'tell app "google chrome" to get the url of the active tab of window 1'

Get the name of the web page in Safari osascript -e 'tell app "safari" to get the name of the current tab of window 1' Get the title of the web page in Google Chrome osascript -e 'tell app "google chrome" to get the title of the active tab of window 1'

You're not limited to single line Applescript code. Here we take the previous two examples and combine them into a single function. #!/bin/bash pageinfo() { osascript -e \ 'tell app "safari" tell the current tab of window 1 return {url & "\n" & ...

A vignette is a long-form guide to your package. Function documentation is great if you know the name of the function you need, but it’s useless otherwise. A vignette is like a book chapter or an academic paper: it can describe the problem that your package is designed to solve, and then show ...

To generate json user model with username, password_hash, email_id, created_at, updated_at, type mix phoenix.gen.json User users username:string email_id:string password_hash:string timestamps()

The following code sample demonstrates a quick and easy means of encrypting and decrypting files using the AES symmetric encryption algorithm. The code randomly generates the Salt and Initialization Vectors each time a file is encrypted, meaning that encrypting the same file with the same password ...
