海外TECH	DEV Community	Quickly and easily create react-contexts and implement state management	https://dev.to/rubenarushanyan/quickly-and-easily-create-react-contexts-and-implement-state-management-2f8n	Quickly and easily create react contexts and implement state management React Component ShellYou can find the full documentation at the React Component Shell is a package that allows you to quickly and easily create react contexts and implement state management Shell is a JavaScript class that has certain methods and properties to provide some type of functionality in the project The main concept is to create shell objects and connect them to react components Installationnpm install react component shell Basic UsageLet s create a Game shell that has two methods run and stop that update the paused property of the state game jsimport Shell from react component shell class Game extends Shell state paused true run this updateState state gt return state paused false stop this updateState state gt return state paused true export Game Now let s use the createShellProvider function to create a react context provider and access hooks for the Game shell game context jsimport createShellProvider from react component shell import Game from game js const GameProvider useGame useGameState createShellProvider shellClass Game export GameProvider useGame useGameState The createShellProvider function returns an array with three values The first value is a provider component the second value is a react hook that returns a shell object and the last value is a react hook that return a state value by a selector In our example we created the GameProvider provider and useGame useGameState hooks Now let s use them in react app App jsimport GameProvider useGame useGameState from game context js const App props gt return lt GameProvider gt lt GamePauseButton gt lt GameProvider gt const GamePauseButton props gt const game useGame const paused useGameState state gt state paused const clickHandler gt if paused game run else game stop return lt button onClick clickHandler gt paused Run Stop lt button gt export default AppIn the example above we can apply the useGame or useGameState hooks to any component inside the lt GameProvider gt useGame returns a game object and we can call its methods run or stop or read and write its properties useGameState selector returns the value of the state of the game which is indicated by the selector function and every time the change of the specified value in the state will result in the re rendering of the given component LinksDocumentationGitHubNPMTwitter	2022-11-05 07:20:07
海外TECH	DEV Community	Static analysis tooling with CMake	https://dev.to/batunpc/static-analysis-tooling-with-cmake-6m7	Static analysis tooling with CMakeRegardless of whether I am an experienced programmer or not it is tough to write the perfect code Ideally I would like to detect every potential flaw and bug and debug them to the appropriate standard in no time But this is a tough concept and relying only upon your developer instincts for analyzing code is insufficient especially if you are writing in C While analyzing code yourself and self proofing is a vital skill that every developer needs to practice having a professional tool like clang tidy gives me more confidence that my code adheres to C standards Setup clang tidy ️I recently integrated clang tidy in palpatine using CMake modules you could browse the cmake directory of palpatine where I kept the StaticAnalyzers cmake module To set this up from scratch first install clang tidy with brew install clang tidy on macOS or if you are on Linux install it with sudo apt get install clang tidy After successfully installing I have added the most commonly used clang tidy checks into the clang tidy dotfile Note Notice the WarningsAsErrors field in this file it is responsible for labeling the warnings as errors Although currently it is not active as I haven t provided any value But if you would like to activate it you could replace the empty value with Power of CMake  See the directory called cmake in the root directory of palpatine Having cmake modules within the directory cmake is commonly used the purpose of doing is to include custom CMake functions to be used later in the project Mine looks like this There are files AddGitSubmodule cmake StaticAnalyzers cmake and corresponding functions palpatine uses Our attention will be on StaticAnalyzers cmake After adding the module StaticAnalyzers cmake we need to configure it in a way that clang tidy will always run whenever we build the project using CMake i e cd build amp amp cmake amp amp make However this might not be the intended behavior in every project maybe you prefer running it at the end after you are satisfied with your implementation for reducing each CMake build time That said there is a neat way of setting this as an option in the file CMakeLists txt Navigate to the root CMakeLists txt file of palpatine and see in this line I have defined a CMake option that lets me switch between weather I decide to use clang tidy or not Now go back to the module StaticAnalyzers cmake and notice the first line we are checking is if the option is turned ON or OFF i e if ENABLE CLANG TIDY If this option was set to OFF CMake would ignore this module if ENABLE CLANG TIDY find program CLANG TIDY COMMAND NAMES clang tidy if NOT CLANG TIDY COMMAND message WARNING CMake RUN CLANG TIDY is ON but clang tidy is not found set CMAKE CXX CLANG TIDY CACHE STRING FORCE else message STATUS CMake RUN CLANG TIDY is ON set CLANGTIDY EXTRA ARGS extra arg Wno unknown warning option endif endif The find program CMake command will search for the clang tidy that is already installed in your system If it is unsuccessful in finding it it will complain with big fat and red warning in the terminal Check if you indeed installed it in your system with clang tidy version If it is successful will indicate your CMake configured clang tidy with no trouble clang tidy in action Run the traditional set of CMake build commands in your terminal in the root directory of palpatine mkdir build amp amp cd build amp amp cmake amp amp makeA combination of these commands is one way of creating a build folder and configuring it with CMake After CMake can see the command clang tidy finally configure it with the project set CMAKE CXX CLANG TIDY CLANG TIDY COMMAND p CMAKE BINARY DIR CLANGTIDY EXTRA ARGS CACHE STRING FORCE add custom target clang tidy COMMAND CMAKE COMMAND build CMAKE BINARY DIR target CMAKE PROJECT NAME COMMAND CMAKE COMMAND build CMAKE BINARY DIR target clang tidy COMMENT Running clang tidy Delete the existing build folder and re run this set of commands mkdir build amp amp cd build amp amp cmake amp amp make to test if clang tidy produces any warnings in the terminal In project palpatine the output looks like the following There is also a vscode extension called CMake Tools from Microsoft It provides this set of buttons that automates the CMake build progress This is beneficial in a way if you want to integrate CMake and visualize the warnings in vscode before running it on CLI If I build palpatine using CMake Tools vscode displays the warning within the file ConclusionC is developing rapidly and reviewing code is not enough to keep up with the latest standards Using static analyzers like clang tidy inevitably helps us to write defect free code You might as well learn from the warnings produced by clang tidy	2022-11-05 07:19:51
