海外TECH	DEV Community	Auto-Completion and Cocktail mixing with Golang’s Cobra CLI	https://dev.to/tomfeigin/auto-completion-and-cocktail-mixing-with-golangs-cobra-cli-h26	Auto Completion and Cocktail mixing with Golang s Cobra CLIAt Raftt we build a dev tool which enables effortless development on Kubernetes envs Development environments created with Raftt can be interacted with and controlled via a CLI program which we built with the Go programming language Recently we added the ability to auto complete the names of Kubernetes resources in the dev env The auto completion feature improved our UX and made many users happy that they can leverage the terminal to auto complete resource names instead of having to type them out In this post we explain how to implement custom auto completion ability for a CLI tool written in Go and using Cobra We start by walking through the creation of a tiny mixologist app using Cobra The mixologist app is a CLI tool written in Go using the Cobra framework that can make cocktails from a list of ingredients and uses custom auto completion to improve the user experience For reference the code for the CLI application can be found here Here is an example of auto completion of the mixologist CLI The post will then cover how to enable basic auto completion of a specific subcommand and finally how to implement custom auto completion The post concludes with a brief discussion of how this feature is used in the Raftt CLI ‍ Create a CLI utility with CobraThis paragraph discusses how to enable auto completion in a CLI tool written in Go using the Cobra framework It walks through the process of creating a small application using Cobra adding a subcommand and implementing basic auto completion for that subcommand It then explains how to implement custom auto completion in order to improve the user experience What is Cobra Cobra is a library for creating powerful modern CLI applications You probably already know about Cobra if you ever wrote a CLI tool in Go but for the few who don t this article contains a short introduction on how to use it For CLI utilities written in Go Cobra is the go to command line wrapper used by the likes of Kubernetes Github CLI Helm and many more In the next section we will build a small application in Go using the cobra framework The mixologist appIn this introduction we will create a mixologist app The app will act as a mixologist which can make a cocktail from a list of ingredients First create the root command for our app cmd root govarrootCmd amp cobra Command Use mixologist Short Mixologist is your personal bartender Long Mixologist acts as a bartender who specializes in cocktail making RunE func cmd cobra Command args string error return cmd Help func Execute if err rootCmd Execute err nil fmt Println err os Exit The rootCmd is the entry point of our mixologist app it prints the help and exits As mentioned before we want our mixologist to mix cocktails to do that we will add the sub command mix The mix subcommand will receive at least arguments controlled by the Args field of the cobra Command cmd mix goimport github com spf cobra golang org x exp slices var mixCmd amp cobra Command Use mix Short make a cocktail Long Mix some ingredients together to make a cocktail Args cobra MinimumNArgs RunE func cmd cobra Command args string error Psuedo code if slices IndexFunc args func s string bool return s Vodka gt amp amp slices IndexFunc args func s string bool return s Orange Juice gt fmt Println You can make a screwdriver cocktail return nil return fmt Errorf i can t make a cocktail from v args func init rootCmd AddCommand mixCmd We now need to tie it all together in our main go file package main ‍import pathToYourApp cmd func main cmd Execute By executing the mixologist with the correct ingredients it can make us a Vodka Screwdriver But if we get the ingredients wrong we will get an error In the next paragraph we will demonstrate how we can leverage cobra to have auto completion in our terminal and make it easier for our users to enjoy our app Basic Auto completionUsers of the mixologist app may find it difficult to guess the available ingredients We should make it easier to use the app by making our CLI utility auto complete an ingredient if it is available in our bar To implement basic auto completion we will set the ValidArgs field of the command like so var availableIngredients string Vodka Gin Orange Juice Triple Sec Tequila simple syrup white rum Kahlua coffee liqueur var mixCmd amp cobra Command Use mix Short make a cocktail ValidArgs availableIngredients Now we need to install the auto completion in our shell cobra can generate auto completion for bash zsh and fish shells out of the box After choosing the shell we can do mixologist completion zsh gt tmp completionsource tmp completionAnd then when we type mixologist tab tab we will get the list of ingredients auto completed That is really cool but it still isn t optimal the command can auto complete ingredients which when mixed together doesn t make any cocktail We want to auto complete the next ingredient only if it can actually combine with all previously mentioned ingredients To achieve that optimal user experience we need to implement custom auto completion we will see how to do that in the next paragraph Custom Auto completionNow our mixologist app auto completes the ingredient list in when pressing tab on the mix subcommand but we want to make it smarter Our opinionated bartender believes that the only thing that can be paired with Vodka is Orange Juice so we want our auto completion to suggest only Orange Juice if the previously mentioned ingredient was Vodka We also don t want to repeat the same ingredient twice so we won t end up mixing Kahlua with Kahlua times To achieve that we need to edit the mix subcommand and use the awesome lo package for some help import github com samber lo var availableIngredients string var mixCmd amp cobra Command Use mix Short make a cocktail ValidArgsFunction func cmd cobra Command args string toComplete string string cobra ShellCompDirective if len args amp amp args Vodka return string Orange Juice cobra ShellCompDirectiveNoFileComp unusedIngredients lo Difference args availableIngredients return unusedIngredients cobra ShellCompDirectiveNoFileComp When we use the auto completion of the mix subcommand by pressing tab twice the terminal will show Notice that selected ingredients do not appear as an option for subsequent auto completions anymore If we give Vokda as the first argument and then press tab twice the terminal will auto complete Orange Juice immediately The new auto completion improved the UX of our mixologist app and made our users much happier Now that we know how to implement custom auto completion using the cobra framework we will discuss in short how we use this feature in the raftt CLI Auto completion in raftt In the Raftt CLI we have implemented custom auto completion using the Cobra framework This feature allows users to easily and quickly input valid Kubernetes resource names when interacting with resources in the Raftt dev environment With custom auto completion users can select only valid resource names improving the overall user experience and preventing frustrating typos If you are following along our tutorial here you can try out our auto complete for yourself when you convert the frontend or recommendations services to dev mode Write raftt dev tab tab and see it list the options The tightly integrated auto completion provided us with blazing fast and effortless UX without having to worry about typos The step where we installed the completion by running the source command above is performed for you if you have installed Raftt using brew or snap Otherwise add eval raftt completion lt SHELL gt to your shell s rc file PerformanceLastly we should briefly touch the efficiency of the auto completion feature if the auto completion logic is complicated or depends on remote services consecutive completions will be slow and result in a bad user experience For example when auto completing a long list of Kubernetes resources by repeatedly pressing the tab tab combination To mitigate this issue we can cache the results of the complicated auto completion logic Caching auto complete results introduces two new problems Where are the results stored The CLI itself only runs for a second to generate the completion and does not stick around We could potentially put them on disk but that means dealing with multiple accessors at once locking etc Raftt has a daemon that it starts up and it was natural to cache the results there Out of date information If our cache is too long we might be serving incorrect information For example if the Kubernetes resources have since been deleted We settled on seconds as a reasonable duration In conclusion implementing custom auto completion for a CLI tool using Cobra can greatly improve the user experience and make the tool more efficient to use By following the steps outlined in this post you can add this feature to your own Go based CLI tool With auto completion users can more easily navigate and interact with your tool reducing errors and improving the overall experience Thank you for auto completing this post The code for the mixologist app can be found here If you are interested in how Raftt can help you be develop effectively on local or remote Kubernetes clusters check out our tutorials here	2023-08-07 12:47:15

海外TECH	DEV Community	How to Create a Sticky NavBar using Tailwind CSS	https://dev.to/bobbyiliev/how-to-create-a-sticky-navbar-using-tailwind-css-1587	How to Create a Sticky NavBar using Tailwind CSS IntroductionWhen building a modern responsive website navigation plays a crucial role in user experience A sticky or affix navigation bar remains visible at the top of the screen as users scroll making it easy for them to access the main menu items without having to scroll back to the top Tailwind CSS a popular utility first CSS framework makes it simple to create elegant functional sticky navigation bars In this tutorial we ll walk you through the process of creating a sticky navigation bar using Tailwind CSS and showcase some stylish designs to inspire your project Step Setting Up the ProjectBefore we start make sure you have Tailwind CSS installed in your project You can either use the CLI include it from a CDN or set up a custom build Visit the official Tailwind CSS documentation to learn how to set up Tailwind CSS for your specific project Step Creating the Basic NavBarFirst let s create a simple navigation bar using Tailwind CSS Add the following HTML code to your project lt DOCTYPE html gt lt html lang en gt lt head gt lt meta charset UTF gt lt meta name viewport content width device width initial scale gt lt link href dist tailwind min css rel stylesheet gt lt title gt Sticky NavBar using Tailwind CSS lt title gt lt head gt lt body class bg gray gt lt header class bg white gt lt nav class container mx auto px py gt lt div class flex justify between items center gt lt a href class text xl font bold text gray gt MyWebsite lt a gt lt div class flex space x gt lt a href class text gray gt Home lt a gt lt a href class text gray gt About lt a gt lt a href class text gray gt Services lt a gt lt a href class text gray gt Contact lt a gt lt div gt lt div gt lt nav gt lt header gt lt Add your page content here gt lt body gt lt html gt This code sets up a basic navigation bar with a container logo and menu links Step Making the NavBar StickyTo make the navigation bar sticky we need to add the fixed top and w full classes to the lt header gt element This will fix the header at the top of the viewport and span the full width of the screen Update your lt header gt tag as follows lt header class bg white fixed top w full gt Now when you scroll down the page the navigation bar will remain at the top Step Adding a ShadowTo create a subtle separation between the sticky navigation bar and the page content add a shadow using the shadow md class lt header class bg white fixed top w full shadow md gt Step Design InspirationsNow that you ve created a basic sticky navigation bar using Tailwind CSS you can customize its design by applying various utility classes or creating your own Here are a few design ideas to inspire you Transparent background with a color change on scroll Add a transparent background to the navigation bar and change the

海外TECH	Engadget	The best laptops for college students	https://www.engadget.com/best-laptops-for-students-130054631.html?src=rss	The best laptops for college studentsWhether you re heading to a physical campus taking classes online or a mix of both a laptop is sure to be the control center for your studies Getting a new machine for the back to school season can better help you stay on top of your schedule and handle your furious multitasking with dozens of tabs devoted to research while you write your essays We re still dealing with the shadow of the pandemic and inflation continues to drive up prices so everything might feel more expensive than ever The good news is laptops are also lasting longer than ever and the options on our list should serve you well for years to come That is as long as you pick one from a reliable company and with the right specs To help you as you shop we put together this collection of things to look out for as well as a list of the best laptops for college What to expectApple has completed its transition to its own Silicon so you ll no longer have the option of Intel powered Macs Nor should you want to really since the M and M MacBooks have proven to be reliable speedy and long lasting With a new generation of chips likely on the horizon older models with M processors should get cheaper while still offering excellent performance This means you ll have more options to consider without having to stretch your budget Meanwhile new PCs keep getting announced with the latest models typically powered by th gen Intel processors or the latest AMD Ryzen chips Though the shift to ARM based systems has been successful for Apple the PC industry is still struggling to keep up and Windows on ARM is basically dead in the water Don t waste your time or money on an ARM based PC they re hard to find nowadays anyway Speaking of laptops with top of the line specs can cost you around to these days For most college students though a midrange machine to use primarily for writing papers and web browsing might be enough Depending on your field of study you could get by with an Intel Core i processor or equivalent with at least GB of RAM If you need to run specialized software for design or programming consider upgrading to a beefier system with more processing power and memory On the other hand if you do most of your coursework online or in a browser getting a Chromebook could save you a lot of money You ll also want to pay attention to a device s weight especially if you plan on lugging your laptop to classes in person There are a lot of premium ultraportables in the inch category with chips like Intel s Core i or i that cost around If these light laptops are too expensive you ll still have respectable options in the to price range but they might be heavier and use older slower processors I ve included our recommendations for the best budget laptops in this college centric guide but we also have more affordable top picks that you can check out as well See Also Best Laptops for Best Gaming LaptopsBest in Laptops for Best ChromebooksBest Cheap Windows Laptops for With some laptop makers deciding to get rid of headphone jacks it s important to check specs lists when you re shopping for newer machines If you don t have wireless headphones or use equipment that plugs into the mm jack you ll want to steer clear of devices like Dell s XPS Plus Finally while most laptops in offer WiFi or E and Bluetooth or later you may not have one of the compatible routers or other devices that would enable those faster connections yet Chances are your campus WiFi might still be stuck on an older setup too so it s not crucial that you get a system with the latest standards yet Of course it doesn t hurt to get a laptop that s future proof but just know that of all the things to look out for WiFi E shouldn t be a dealbreaker in your decision making process The best laptops for college studentsBest Apple MacBook AirIt s hard to beat Apple s MacBook Air if you want a powerful machine for college that won t weigh you down You actually have a few good options this year ーthe new inch M powered MacBook Air last year s inch model and the MacBook Air M The M laptop earned a score of from us for its impressive performance gorgeous inch Liquid Retina display and its refined design that s even thinner than the M version that came before it Our biggest gripe with this laptop is its price tag ーthe M MacBook Air will set you back more than the M so you re looking at spending at least if you want the latest and greatest from Apple Even though it s older the Apple M MacBook Air is a great laptop outperforming many PCs while maintaining a fanless design It s also cheaper starting at You ll still get a great keyboard and long battery life along with a nice Retina display Of course it uses a p webcam while newer models have sharper p cameras in They re housed in notches because Apple shaved down the bezels for a more modern look so if that bothers you it might be best to grab an M model while you can You ll have to live with having just two USB C charging ports since only the M machines have the additional MagSafe socket but if you re already living a largely wireless life and don t mind a not so great camera you might find the M MacBook Air is a solid deal Read our full review of the Apple MacBook Air MBest Windows Dell XPS PlusThe best PC has long been Dell s well rounded XPS series and I still recommend it to anyone that doesn t want a Mac Yes the XPS Plus lacks a headphone jack and some of its buttons are hard to see and use But the XPS is a well rounded machine and reliable workhorse that will get you through classes and late night writing sessions without breaking a sweat Like its predecessors the XPS Plus offers a lovely OLED screen with impressively thin bezels and packs a roomy comfortable keyboard It also features a new minimalist design that looks more modern and offers a performance boost over the standard model The row of capacitive keys at the top in lieu of traditional function keys may irk some as they can be hard to see outdoors but if you become familiar with where they are you might not need to see where they are to find the right ones The invisible trackpad can also be tricky since its boundaries aren t clear If you don t like the changes Dell has made to the XPS or if you definitely need a headphone jack the older generations are still solid options There s also the Samsung Galaxy Book series which feature beautiful OLED screens and sharper webcams in thin and light frames I also like Microsoft s Surface Laptops and the most recent edition offers great performance and battery life albeit in an outdated design Read our full review of the Dell XPS Plus laptopBest for gaming Razer Blade Just because your laptop might primarily be for coursework doesn t mean you can t use it for fun too Those looking to game on their machines should prioritize responsive screens and ample ports for their favorite accessories that can best help them defeat their virtual enemies If you re considering a gaming first machine that you can use for school check out our guide to buying a gaming laptop It covers details about different CPUs and GPUs minimum specs and more Our favorite gaming laptop is the Razer Blade which has an Intel Core i processor and an NVIDIA RTX graphics for At that price point it s the most expensive item on this list but you also get a inch quad HD screen that refreshes at Hz Different configurations are available depending on your preference including Full HD Hz and K Hz versions The Blade series is also one of the most polished gaming laptops around and Razer consistently updates it with the latest processors graphics and other hardware advancements If you really want to go all out you could consider the new Razer Blade that has NVIDIA s RTX or GPUs Students and gamers looking for something cheaper and more portable should consider the ASUS ROG Zephyrus G which was our favorite model in The main reason it got bumped down a notch is because the refresh is almost more expensive It s still a solid gaming laptop though with an excellent display roomy trackpad and plenty of ports in spite of its thin profile Read our full review of the Razer Blade gaming laptopBest Chromebook Lenovo IdeaPad Flex i ChromebookIf you can do most of your schoolwork through web based apps a Chromebook is worth considering for your college laptop Sure they don t generally look fancy nor have high end specs But they re often more affordable and have longer battery life Our favorite Chromebook is Lenovo s IdeaPad Flex i Chromebook which Engadget s resident Chrome OS aficionado Nathan Ingraham described as hitting “the sweet spot for a lot of Chromebook buyers This laptop nails the basics with a inch Full HD touchscreen that s bright and sharp an excellent backlit keyboard and an th generation Intel Core i processor The GB of RAM and GB of storage may sound meager but it s more than enough for a Chromebook especially at this price It s also nice to see USB A and USB C ports a microSD card slot and eight hour battery life Weighing pounds and measuring inches thick the Flex i is not the lightest or slimmest laptop around but hey at least your wallet won t also feel light as feathers after buying this Notably the Flex i is supposed to receive software and security updates until June of so it will last you for years to come That s nice to see considering this laptop has been out for more than a year now and we re expecting Lenovo to release a replacement soon When that happens or if another manufacturer launches a comparable option we will update this list The Lenovo Flex i is no longer available directly from Lenovo but you can commonly find it on Amazon for about as of this writing it is selling for about That s an outstanding value Read our full review of the Lenovo Flex Chromebook Best budget HP Pavilion Aero If you re looking for a sturdy student laptop under your best bet is the HP Pavilion Aero Yes it s almost two years old but it s still one of the best cheap laptops for college students available now For an affordable price you ll get a Full HD screen with a aspect ratio and surprisingly thin bezels as well as a comfortable keyboard and spacious touchpad Importantly the Aero provides relatively powerful components compared to others in this price range with an AMD Ryzen series processor and Radeon graphics Plus it has a generous array of ports and enough hours of battery life to last you a full day and then some Read our full review of the HP Pavilion Aero laptopBest Convertible Microsoft Surface Pro For those who need their laptops to occasionally double as tablets the Surface Pro series is a no brainer Compared to notebooks or in laptops with rotating hinges tablets with kickstands are often much slimmer and lighter The Surface Pro is the most recent model and it features Microsoft s sleek design with a thinner profile and minimal bezels The Pro also has a Hz display that makes scrolling long documents or spreadsheets feel much faster and you can drop the refresh rate down to Hz if you want to conserve battery life Just make sure you get an Intel processor rather than an ARM based configuration since app compatibility might be an issue on the latter You don t want to be the only one in class who can t install the obscure app that your professor wants everyone to use do you We also like Microsoft s Type Covers and the Surface Pens though it s worth noting that they ll have to pay extra for both if you want them Unless you re bent on sticking to Apple s ecosystem in which case an iPad Pro would suit you best the Surface Pro is arguably the best convertible laptop around Read our full review of the Microsoft Surface Pro This article originally appeared on Engadget at	2023-08-07 12:20:38
