海外TECH	DEV Community	Flutter Inception: A Free Shorebird Alternative	https://dev.to/codeontherocks/flutter-inception-a-free-shorebird-alternative-5hif	Flutter Inception A Free Shorebird AlternativeThere is an intimacy between web developers and their users that native app developers are jealous of Within minutes of finding and diagnosing a software bug web developers can publish a fix that all of their users will see There is no laborious back and forth with a third party app store or a day wait for an simple app review The web developer builds their new application and sends it to the masses Native app developers are not so lucky App review times on the Google Play and Apple App stores are infamously unpredictable and long delaying what could have otherwise been immediate fixes for an indeterminate amount of time This slow but necessary step can ultimately lead to poor reviews lost users and developer frustration Flutter developers in particular are negatively impacted by these review process because they typically aim to publish their apps on all platforms Every time they are ready to release an update they must ask themselves Am I ready for two app reviews Many other cross platform developers face the same soul crushing processes but in this article I want to present a potential solution for the Flutter crowd On the Web and in your PocketFlutter is special among cross platform frameworks because it works on Android iOS and the web with very little modification In fact every Flutter web application can be downloaded as a progressive web app PWA that performs similarly to a native application In my opinion PWAs are a valid solution to the app review problem because they allows developers to publish updates at their own pace without sacrificing too much of the native experience The issue with this approach of course is that a majority of people don t know how to download a PWA and among those that do the willingness to do so is low Forget the PWA experience then Even if users don t download your Flutter app as a PWA they can still use it in their browser which allows them the benefit of real time updates While good this solution is not perfect either because native apps are still more performant and the app stores provide a level of trust that the wild web does not If not a PWA or web app then what Well what if we could have both What if we could have the native app experience of the time and the web experience the other What if we could have our cake and eat it too That would be nice The final solution I propose is to ship your native apps with a webview fallback When the latest version of your app has passed app store review users will get the native experience When the latest version of your app is still in review users will get the web experience From a user perspective the difference should be subtle to the point of being unnoticeable which is leaps and bounds better than them seeing a bug Whether or not the webview is used can be determined by a simple API call to your server a Firebase Remote Config value or an automated process that compares the current native version to the latest web version The rest of this article will discuss the setup in more details Deployment ApproachMy personal suggestion is to take a web first approach to app development Web applications are faster to update globally accessible and many browsers include a mobile device emulator that makes testing the responsiveness of your app as easy as resizing your browser window By making your application welcoming to web travelers you will make it welcoming to all users regardless of the color of their SMS messages A specific suggestion would be to develop and test your application on a chrome browser using the built in dev tools to emulate how it would look on a mobile device When everything looks good to go ship it and start testing on native platforms Taking this approach will ultimately lead to a drastically higher number of web deployments compared to Android or iOS deployments but that s fine If you re marketing campaigns are web focused most of your traffic will be browser bound anyway Code Web ApplicationThe first step is to create a web application that will be used as the fallback for your native app This application should be hosted on a server that you control and should be accessible via a URL The URL can be stored in your app as a global variable or passed to your application using dart define I recommend using a Firebase Hosting since its super easy to setup Develop this application as you would any other Flutter application and publish it In App WebviewTo effectively implement this solution you ll need a trusty webview package that works on both Android and iOS platforms I prefer to use the flutter inappwebview package which you can add to your pubspec yaml using the following line flutter inappwebview There is a beta version of this plugin that also works on the webOnce you ve added the dependency the next step is to create an app webview widget with the sole purpose of displaying your web application in a webview A small visual indicator like a different colored status bar when the app is using thewebview can help you avoid being confused during development The bare bones code looks like this class AppWebview extends StatefulWidget const AppWebview Key key super key key override State lt AppWebview gt createState gt AppWebviewState class AppWebviewState extends State lt AppWebview gt final GlobalKey webViewKey GlobalKey InAppWebViewController webViewController override Widget build BuildContext context return Scaffold appBar AppBar toolbarHeight backgroundColor Colors black body InAppWebView key webViewKey pullToRefreshController pullToRefreshController initialUrlRequest URLRequest url WebUri const String fromEnvironment APP WEBVIEW BASE URL onWebViewCreated controller webViewController controller The webview variant of your native app doesn t need to use the router your app normally uses ex auto route go router etc so you can add it directly to a MaterialApp widget The app inside the webview will use the router as designed The biggest problem with this code is that your native application will think it only has a single route In other words the native Android and iOS apps can t see the router in the webview One tap of the Android back button or a single right swipe on iOS will close the application completely We don t want that To fix this we need to wrap the webview widget in a WillPopScope widget that will detect back button presses and communicate them to the webview controller If the webview can navigate backwards in its history a back button press should do that instead of closing the app return WillPopScope onWillPop async final controller webViewController if controller null if await controller canGoBack controller goBack return false return false child Scaffold appBar AppBar toolbarHeight backgroundColor Colors black body webview code When to WebviewNow that we have a webview set up we need to decide when to use that instead of the normal app This part is up to you but I ll provide a few ideas here Since the app stores operate at different speeds its a good idea to create separate flags for Android and iOS Firebase Remote ConfigFirebase Remote Config lets you create and update feature flags easily through your project s Firebase console On the Remote Config tab add two new boolean parameters android webview and ios webview set them to false and publish the changes When a platform should use the webview change its corresponding flag to true and publish In the app you can read these values using the firebase remote config package The following code sets up the remote config and reads the values for the android webview and ios webview flags final remoteConfig FirebaseRemoteConfig instance Future lt void gt setup async await remoteConfig setConfigSettings RemoteConfigSettings fetchTimeout const Duration minutes minimumFetchInterval const Duration hours await remoteConfig setDefaults android webview false ios webview false await remoteConfig fetchAndActivate bool get androidWebview gt remoteConfig getBool android webview bool get iosWebview gt remoteConfig getBool ios webview Pros Fast to changeFast to deployCons Requires Firebase project and packagesNot always immediate Dart EndpointIf you re a full stack Dartists creating a simple endpoint using Dart Frog can be a fast way to add remote control to your app Create a new endpoint that returns a boolean value for each platform When the endpoint is hit the app can read the value and decide if it should use thewebview Pros Fully customizableLightweightCons Requires a new server deploy for each change More setupIf you d rather your app automatically detect when it should use the webview you can tweak this implementation slightly and store the latest version in Remote Config or on your server Then when your native apps start up they can check their own version against this server version and decide if the webview is necessary You can get the current version of your app using the package info plus package Add it to your pubspec yaml package info plus Then in your main dart file you can get the current version of your app final packageInfo await PackageInfo fromPlatform final currentVersion packageInfo version Regardless of how you decide to set these flags the implementation on the frontend will look similar If the app is running on the web it should never use the webview If its running on native Android or iOS it should check the relevant flag and decide what to do class MyApp extends StatelessWidget MyApp super key final MaterialApp baseApp MaterialApp router routerConfig router config theme ThemeData colorScheme ColorScheme fromSeed seedColor Colors deepPurple useMaterial true override Widget build BuildContext context return Builder builder context if kIsWeb return baseApp else bool androidWebview Platform isAndroid amp amp remoteConfigService androidWebview bool iosWebview Platform isIOS amp amp remoteConfigService iosWebview bool showWebView androidWebview iosWebview if kIsWeb amp amp showWebView return const MaterialApp home AppWebview else return baseApp What about the Guidelines According to section of the Apple Developer guidelines Apps should be self contained in their bundles and may not read or write data outside the designated container area nor may they download install or execute code which introduces or changes features or functionality of the app including other apps Educational apps designed to teach develop or allow students to test executable code may in limited circumstances download code provided that such code is not used for other purposes Such apps must make the source code provided by the app completely viewable and editable by the user If we re comparing the webview fallback method to Shorebird dev I d argue that the webview approach is more acceptable since the contents of the users app does not change until they want it to by updating the app through the App Store ConclusionIf you ve ever accidentally shipped a bug to production you know what true helplessness feels like Regardless of how simple the fix is you can be stuck watching users encounter the bug for hours or even days as stakeholders question you about when it will be squashed Its a stressful time and stress is bad for your health With the webview fallback solution I ve described here you might just get days of your life back Most of the time your users will see the native experience they re used to For the other handful of times when a bug has crept into prod or a much needed update is standing in the TSA line you can flip a switch and sleep easy How can you beat that	2023-08-10 15:44:12

transitions should be appliedtransition duration specifies the duration over which transitions should occurtransition timing function specifies a function to define how intermediate values for properties are computedtransition delay specifies a delay in seconds for the transition effectUsing CSS Transitions How to create a transition effectHow to specify the speed curve of the transitionHow to delay the transition effectHow to change several property valuesBrowser Support for Transitions Overview of browser support for CSS transitionsHow to ensure cross browser compatibilityAdvanced Topics Using cubic bezier functions to define custom easing functionsCombining CSS transitions with other CSS techniques such as transforms and animationsConclusion and Further Resources Summary of key pointsLinks to further resources for learning about CSS transitionsIntroduction to CSS TransitionsDefinition of CSS transitionsCSS transitions provide a way to control animation speed when changing CSS properties Instead of having property changes take effect immediately you can cause the changes in a property to take place over a period of time¹ For example if you change the color of an element from white to black usually the change is instantaneous With CSS transitions enabled changes occur at time intervals that follow an acceleration curve all of which can be customized¹ How CSS transitions workCSS transitions let you decide which properties to animate by listing them explicitly when the animation will start by setting a delay how long the transition will last by setting a duration and how the transition will run by defining an easing function e g linearly or quick at the beginning slow at the end ¹ The Web author can define which property has to be animated and in which way This allows the creation of complex transitions However some properties are not animatable as it doesn t make sense to animate them¹ Examples of CSS transitionsHere are some examples of CSS transitions Simple example A div element with a specified transition effect for the width property with a duration of seconds The transition effect will start when the specified CSS property width changes value div width px height px background red transition width s div hover width px Multiple animated properties example A div element with a transition effect for both the width and height property with a duration of seconds for the width and seconds for the height div width px height px background red transition width s height s div hover width px height px Using transitions when highlighting menus A common use of CSS is to highlight items in a menu as the user hovers over them This can be achieved using CSS transitions ul li display inline block margin right px position relative padding px px background color eee cursor pointer transition all s ease in out ul li hover background color ddd transform scale Properties of CSS TransitionsCSS transitions provide a way to control animation speed when changing CSS properties Instead of having property changes take effect immediately you can cause the changes in a property to take place over a period of time¹ The transition is the combination of four properties which are listed below transition property It specifies the CSS properties to which a transition effect should be applied Only properties listed here are animated during transitions changes to all other properties occur instantaneously as usual² For example if you want to apply a transition effect to the width property of an element you can specify it like this div transition property width transition duration It specifies the length of time a transition animation should take to complete You can specify a single duration that applies to all properties during the transition or multiple values to allow each property to transition over a different period of time² For example if you want the width transition to take seconds you can specify it like this div transition duration s transition timing function It specifies a function to define how intermediate values for properties are computed Easing functions determine how intermediate values of the transition are calculated² For example if you want the width transition to have an ease in out timing function you can specify it like this div transition timing function ease in out transition delay It defines how long to wait between the time a property is changed and the transition actually begins² For example if you want the width transition to start after a delay of second you can specify it like this div transition delay s All these properties can be combined into one shorthand property transition The syntax is div transition lt transition property gt lt transition duration gt lt transition timing function gt lt transition delay gt For example if you want to apply a transition effect to the width property of an element with a duration of seconds an ease in out timing function and a delay of second you can specify it like this div transition width s ease in out s Using CSS TransitionsCSS transitions provide a way to control animation speed when changing CSS properties Instead of having property changes take effect immediately you can cause the changes in a property to take place over a period of time¹ How to create a transition effectTo create a transition effect you must specify two things the CSS property you want to add an effect to and the duration of the effect³ For example if you want to apply a transition effect to the width property of an element with a duration of seconds you can specify it like this div width px height px background red transition width s div hover width px How to specify the speed curve of the transitionThe transition timing function property specifies the speed curve of the transition effect This property can have several values including ease linear ease in ease out and ease in out³ For example if you want the width transition to have an ease in out timing function you can specify it like this div width px height px background red transition width s ease in out div hover width px How to delay the transition effectThe transition delay property specifies a delay in seconds for the transition effect For example if you want the width transition to start after a delay of second you can specify it like this div width px height px background red transition width s ease in out transition delay s div hover width px How to change several property valuesYou can change several property values at once by specifying multiple properties in the transition shorthand property For example if you want to apply a transition effect to both the width and height properties of an element with a duration of seconds for the width and seconds for the height you can specify it like this div width px height px background color red transition width s height s div hover width px height px Browser Support for TransitionsOverview of browser support for CSS transitionsCSS transitions are widely supported in modern browsers According to Can I use CSS transitions are supported by of global users¹ This includes support in all major browsers such as Chrome Firefox Safari Edge and Opera¹ However it is important to note that older versions of some browsers may require vendor prefixes to use CSS transitions For example older versions of Chrome and Safari may require the webkit prefix³ How to ensure cross browser compatibilityTo ensure cross browser compatibility with CSS transitions you can follow these steps Determine your target browsers It is important to determine which browsers your target audience is likely to use This will help you focus your testing efforts on the most relevant browsers⁵ Use vendor prefixes Vendor prefixes are a way for browser makers to add support for new CSS features before those features are fully supported in all browsers By using vendor prefixes developers can use new CSS features in the browsers that support them instead of waiting for all browsers to catch up For example if you need to support older versions of Chrome and Safari you may need to use the webkit prefix for the transition property¹ Here is an example of how to use vendor prefixes for the transition property div width px height px background red webkit transition width s For older versions of Chrome and Safari transition width s div hover width px In this example we use the webkit prefix for the transition property to ensure that the transition effect works in older versions of Chrome and Safari We also include the unprefixed version of the transition property to ensure that the transition effect works in other browsers that support CSS transitions Test on multiple browsers It is important to test your website on multiple browsers to ensure that the transitions work as expected You can use tools such as LambdaTest or BrowserStack to test your website on a range of different browsers and devices Provide fallbacks In case some users are using a browser that does not support CSS transitions it is a good idea to provide fallbacks For example you can use JavaScript animations as a fallback for browsers that do not support CSS transitions Advanced TopicsUsing cubic bezier functions to define custom easing functionsCubic BezieBeziertions are a powerful tool for creating custom easing functions in CSS transitions These functions allow you to define the speed curve of a transition giving you precise control over how the animation progresses over time A cubic bezier function is defined by four values which represent the x and y coordinates of two control points on a cubic bezier curve The first and last points of the curve are fixed at and respectively By adjusting the position of the two control points you can create a wide variety of easing functions Here are some examples of how to use cubic bezier functions in CSS transitions Example Bounce effectdiv width px height px background red transition all s cubic bezier div hover width px In this example we use a cubic bezier function to create a bounce effect when the width of the div element changes The transition starts quickly slows down in the middle and then speeds up again towards the end Example Elastic effectdiv width px height px background red transition all s cubic bezier div hover width px In this example we use a cubic bezier function to create an elastic effect when the width of the div element changes The transition starts slowly speeds up in the middle and then overshoots its target before settling back to its final value Example Custom ease in out effectdiv width px height px background color red transition all s cubic bezier div hover width px In this example we use a cubic bezier function to create a custom ease in out effect when the width of the div element changes The transition starts slowly and ends slowly with a fast change in between These are just a few examples of how you can use cubic bezier functions to create custom easing functions in CSS transitions By adjusting the values of the cubic bezier function you can create an almost infinite variety of easing effects to suit your needs Combining CSS transitions with other CSS techniques such as transforms and animationsCombining CSS transitions with other CSS techniques such as transforms and animations can create truly immersive and engaging web experiences Transforms allow you to modify an element s position rotation scale and other properties while transitions enable you to animate those changes smoothly over a specified duration Here are some examples of how to combine CSS transitions with other CSS techniques Example Rotating an element continuouslydiv width px height px background color red animation rotate s linear infinite keyframes rotate from transform rotate deg to transform rotate deg In this example we use a CSS animation to continuously rotate a div element The animation property specifies the name of the animation rotate the duration of the animation s the timing function linear and the number of times the animation should repeat infinite The keyframes rule defines the start and end states of the animation with the transform property being used to specify the rotation Example Creating a hover effect with a D perspectivediv width px height px margin px background color red transition transform s transform style preserve d div hover transform perspective px rotateY deg In this example we use a CSS transition to create a hover effect with a D perspective When the user hovers over the div element it rotates around its Y axis giving the impression of a D flip The transition property specifies that the transform property should be animated over a duration of s The transform style property is set to preserve d to enable D transformations On hover the transform property is updated to specify a perspective and a rotation Example Creating a card flip animation container width px height px position relative border px solid ccc perspective px card width height position absolute transform style preserve d transition transform s card hover transform rotateY deg front back width height position absolute backface visibility hidden front background color red back background color green transform rotateY deg In this example we use a CSS transition to create a card flip animation The container element has a perspective property set to give the impression of depth The card element has a transition property set to animate changes to the transform property over a duration of s The front and back elements represent the front and back of the card respectively When the user hovers over the card element its transform property is updated to rotate it around its Y axis giving the impression of a card flip Here are some more examples of combining CSS transitions with other CSS techniques Example Creating a smooth scrolling effecthtml scroll behavior smooth In this example we use the scroll behavior property to create a smooth scrolling effect when the user clicks on an anchor link The scroll behavior property specifies whether the scrolling should be smooth or instant By setting the value to smooth the browser will automatically animate the scrolling when the user clicks on an anchor link Example Creating a fade in effect fade opacity transition opacity s fade hover opacity In this example we use a CSS transition to create a fade in effect when the user hovers over an element The transition property specifies that changes to the opacity property should be animated over a duration of s When the user hovers over the element its opacity is updated from to creating a smooth fade in effect Example Creating a slide in effect slide position relative left px transition left s slide hover left In this example we use a CSS transition to create a slide in effect when the user hovers over an element The transition property specifies that changes to the left property should be animated over a duration of s When the user hovers over the element its left property is updated from px to creating a smooth slide in effect Summary of key pointsCSS transitions provide a way to control animation speed when changing CSS properties The transition is the combination of four properties transition property transition duration transition timing function and transition delay You can create a wide variety of transition effects by combining these properties in different ways CSS transitions are

海外TECH	DEV Community	CSS TRANSFORM	https://dev.to/stanthewebdev/css-transform-2mjb	CSS TRANSFORMThe CSS transform property allows you to apply geometric transformations to an element such as rotating scaling skewing or translating it Here is a list of all the CSS transform functions along with examples matrix The matrix function describes a homogeneous D transformation matrix It takes six values representing the elements of a x matrix Here is an example that shows how to use the matrix function to scale and skew an element example transform matrix matrixd The matrixd function describes a D transformation as a x homogeneous matrix It takes sixteen values representing the elements of a x matrix Here is an example that shows how to use the matrixd function to rotate and scale an element in D space example transform matrixd perspective The perspective function sets the distance between the user and the z plane It takes one value representing the distance in pixels Here is an example that shows how to use the perspective function to create a perspective effect on an element example transform perspective px rotateY deg rotate The rotate function rotates an element around a fixed point on the D plane It takes one value representing the angle of rotation in degrees or radians Here is an example that shows how to use the rotate function to rotate an element by degrees example transform rotate deg rotated The rotated function rotates an element around a fixed axis in D space It takes four values the x y and z coordinates of the axis of rotation followed by the angle of

海外TECH	DEV Community	Getting Started with Hy, the Python Lisp: a Matplotlib example - Ep. 2	https://dev.to/gicrisf/getting-started-with-hy-the-python-lisp-a-matplotlib-example-ep-2-7jm	Getting Started with Hy the Python Lisp a Matplotlib example Ep In the previous episode we briefly saw what Hy is what it means that it is a dialect of Lisp how to install it and step by step we wrote a small example to create a line plot in matplotlib strictly following the imperative approach we would have used in Python import matplotlib pyplot as plt setv x values setv y values setv fig ax plt subplots ax plot x values y values marker o ax set xlabel X values ax set ylabel Y values ax set title Simple Line Plot plt savefig img hy plt example png If you don t understand something about the code above I recommend referring to the first part maybe something just went unnoticed until now If instead everything is clear we can proceed Now it s time to make things more spicy by adopting a functional approach More precisely we will begin by encapsulating everything in a let What is a let Before rewriting our code it is important to understand what a let is and why it is so useful If you are already familiar with this concept feel free to skip this paragraph and proceed directly to the code A let is a Lisp operator that allows you to create a lexical context with new local variables Basically it s like saying you want to call a function that can access these variables and prioritize these variable declarations over other external ones with the same name How does it works A let expression has two parts First comes a list of instructions for creating variables each of the form variable expression Each variable will initially be set to the value of the corresponding expression After the list of variables and values comes a body of expressions which are evaluated in order Graham ANSI Common Lisp p In Hy terms let x print x The x variable defined in the head of the let is not accessible outside it Actually the Hy let is pretty special because it makes you write variables that have access to the ones defined previously in the same expression For example let x y z x y print x print y print z As you can see here the z variable is defined in relation to x and y As the documentation explains Like the let of many other Lisps let executes the variable assignments one by one in the order writtenThis means that as let in other lisps let in Hy is functionally equivalent to a series of pure nested lets Let s plotBeing conscious of how let works in Hy we can now rewrite the initial code import matplotlib pyplot as plt let x values y values fig ax plt subplots ax plot x values y values marker o ax set xlabel X values ax set ylabel Y values ax set title Simple Line Plot plt savefig img hy plt example png Remember that let blocks can be nested For example in the case we want to plot two identical graphs but with different labels we could write import matplotlib pyplot as plt let x values y values English version let fig ax plt subplots ax plot x values y values marker x ax set xlabel X values ax set ylabel Y values ax set title First Title plt savefig img hy plt example en png Italian version let fig ax plt subplots ax plot x values y values marker o ax set xlabel Ascisse ax set ylabel Ordinate ax set title Secondo titolo plt savefig img hy plt example it png This code saves two figures an English one and an Italian one MacrosLisp code including Hy code is expressed as a series of lists Its minimalist syntax or rather the lack of it allows for easy writing of macros But what is a macro The most common way to write programs that write programs is by defining macros Macros are operators that are implemented by transformation You define a macro by saying how a call to it should be translated This translation called macro expansion is done automatically by the compiler So the code generated by your macros becomes an integral part of your program just as if you had typed it in yourself Graham ANSI Common Lisp p In other words macros are operators that write code and lisps are particularly good for metaprogramming which means the code itself is treated as data that can be manipulated by itself allowing for powerful generative techniques This means also that we can build up our own language to make the code drier or more comfortable Lisp is designed to be extensible it lets you define new operators yourself Graham ANSI Common Lisp p Going metaLet s see how we can leverage the power of macros in this case If you require a series of similar plots with only the title and filename being changed you can write import matplotlib pyplot as plt defmacro plot with title title fname quasiquote let fig ax plt subplots ax plot x values y values marker o ax set xlabel Ascisse ax set ylabel Ordinate ax set title unquote title plt savefig unquote fname let x values y values plot with title First title img hy plt example one png plot with title Second title img hy plt example two png We can dream bigger by creating abstractions for all line plots import matplotlib pyplot as plt defmacro lineplot x y title fname marker xlabel ylabel quasiquote let x values unquote x y values unquote y fig ax plt subplots ax plot x values y values marker unquote marker ax set xlabel unquote xlabel ax set ylabel unquote ylabel ax set title unquote title plt savefig unquote fname lineplot Titolo img hy plt example one png o X values Y values As long as the macro definition is under your eyes it s easy to understand the order in which to write the arguments In this example first the values for x and y then the title followed by the path of the image to be saved the marker and the labels But this is just a simplified situation usually the macro definition is hidden in a library out of sight so named arguments should be preferred over positional arguments Unfortunately this is not directly possible in Hy because as described in the documentation defmacro cannot use keyword arguments because all values are passed to macros unevaluated All arguments are passed positionally but they can have default values defmacro a macro a b a b a macro a macro a macro b b Thankfully there s a nifty workaround to achieve to have both the default values and the positional arguments Instead of them being assigned in the macro we write a simple wrapper function Then we use the function for Defining the default values Giving names to macro s positional arguments import matplotlib pyplot as plt defmacro macro lineplot x y title fname marker xlabel ylabel quasiquote let x values unquote x y values unquote y fig ax plt subplots ax plot x values y values marker unquote marker ax set xlabel unquote xlabel ax set ylabel unquote ylabel ax set title unquote title plt savefig unquote fname defn lineplot x y title Title fname fname png marker o xlabel X values ylabel Y values macro lineplot x y title fname marker xlabel ylabel The asterisk tells which parameters need the key If the symbol is given in place of a parameter it means that all the following parameters can only be set by name In other words we have assigned default values that can be overridden by using the key s name Ultimately assuming the macro is externalized in a library the original code simplifies to these practical and fully functional lines lineplot title Simple Line Plot fname img hy plt example last png Of course this is the simplest example I could think of and there is room for a lot of improvement but I think it makes the potential of the language and macros quite evident Moreover keep in mind that the thrill lies in the fusion of these two powerful languages By keeping the hy package as a dependency Hy macros can be imported and used directly in Python code This allows you to easily share the wrapper function with non Hy users ConclusionIn this post we have discussed how to effectively use lexical scoped blocks and macros Macros provide a powerful tool for metaprogramming allowing you to extend the language and write code that is both cleaner and more expressive By understanding and utilizing these features in Hy you will be able to write more reliable code while still benefiting from Python libraries Originally posted on Zwitterionic Digressions Cover image realized with the help of openjourney	2023-08-10 15:17:04
