海外TECH	DEV Community	Using tree data structures to implement terminal split panes - more fun than it sounds	https://dev.to/kevinyang372/using-tree-data-structures-to-implement-terminal-split-panes-more-fun-than-it-sounds-2kon	Using tree data structures to implement terminal split panes more fun than it soundsMost popular command line tools and code editors like VSCode and Tmux support split panes they provide a handy way for users to visually organize different workflows and keep track of processes that are happening in parallel One of the first things I learned when doing web development was to have two panes one for running the server and one for checking and pushing code to Github Using split panes is one thing building them is another I never thought I would need to build split panes from scratch until I joined Warp at Warp we are building a high performance terminal written entirely in Rust As part of building it we had to build native split panes Here are our key product requirements Developers should be able to Infinitely split the screen in any direction approximately Remove panes from the screen Navigate across panes with arrow keys Arbitrarily resize panes Representing panes in a two dimensional array The first piece is figuring out what data structure to use to represent these panes The first data structure that comes to mind to represent panes is a two dimensional array Intuitively it has some great properties we could take advantage of for example it captures how panes are laid out visually so if we want to navigate in a certain direction we simply need to change the row and column index to get the target pane Pushing new panes is straightforward as well we just need to either insert it into an empty cell or create a new row column if the cell is currently occupied Figure Example of a screen split into four panes and its representation with a two dimensional array Intuitive as it may be we encountered some issues Representation ends up becoming sparse Users should be able to split the panes in any arbitrary way they could have two panes on row and five panes on row This will fill the two dimensional array with many empty cells As a result navigation becomes harder since simply increasing or decreasing the current cell s row column index might lead to an empty cell Performance does not scale Inserting and removing panes could be memory expensive For example if we need to insert a new pane to the right of pane we will have to allocate a new row and shift the content of every pane in the rows after This will get increasingly expensive as users create more panes Representing panes with treesThe Zed editor originally created by Nathan Sobo provides an interesting approach using trees to represent panes Trees are well suited for this problem Trees could be unbalanced This solves the obstacle we had when using the two dimensional array as we could split panes in any arbitrary way and still represent them efficiently in a tree Trees could be recursive We won t need to worry about allocating an entire new row or column for each pane Instead we just need to insert a new branch when a user adds another pane Trees could be hierarchical We could represent the relationship between panes and their sub panes with parent nodes and child nodes Each tree can have only two different types of nodes a branch or a pane node A pane node as its name suggests represents a pane on the screen This should always be a leaf node within a tree A branch node holds information about the spatial relationships between its children In our use case the branch node represents the direction a pane is split which can be either vertical or horizontal An example of how a snapshot of pane state could be represented as a tree is shown below Figure Example of a screen split into three panes and its representation with a tree The way we define pane trees and their components in Warp looks like the following Node BranchNode PaneNode Direction Horizontal Vertical BranchNode split direction Direction children Node PaneNode id How to Add and Remove Panes After we settled on trees as the data structure we had to figure out how to modify these trees to add and remove panes For adding panes we could consider it as “splitting the current pane node into a branch with two child nodes For example in the simple case when user hits split horizontally on a single pane the tree before and after the action would look like the following Figure Change of tree state when adding a new paneWhat about panes that are nested under other branches This becomes more complicated as we could have two different scenarios splitting in the same direction and splitting in a different direction as the parent branch Splitting in the same directionSplitting in a different directionThe algorithm we use here is to recursively traverse down the tree until we locate the deepest branch that hosts the current pane depth first search In case the branch s split direction is the same as the new pane s split direction we simply insert a new pane node into the children vector When the split direction is different we instead replace the pane node with a new branch node that has the new split direction and the current and new added panes as its children Removing panes is very similar to the reverse of adding panes There s one special case we need to keep in mind if a branch node has only one pane node we should collapse them into one pane node as there is no longer a “split Thus the algorithm should keep track of the branch s children size after removing the target pane once it s below the size of two we return the last pane node and the parent branch should replace the branch node with the returned pane node With regard to the performance of adding and removing panes the run time complexity should be O N where N is the number of nodes in the tree The main source of algorithm runtime is from the depth first algorithm used to locate the current pane The memory complexity should be O since we only need to change the target pane and its parent branch at most Tree for all of the split panes Holds the root node pub struct PaneData pub root PaneNode Single Node in the tree of panes pub enum PaneNode A collection of terminals split in a specific direction Branch PaneBranch A single terminal Leaf EntityId The result of attempting to remove a pane from a branchenum BranchRemoveResult The pane was not found in this sub tree NotFound The pane was found and removed no further action is needed Removed The pane was found and removed leaving only a single node in the branch so it needs to be collapsed into the parent Collapse

nodes return BranchRemoveResult Collapse self nodes pop unwrap else return BranchRemoveResult Removed BranchRemoveResult NotFound Navigating Panes with Arrow KeysOne challenge we encountered when creating split panes was supporting navigation with arrow keys in a way that mapped to the visual layout of the panes Although visually the panes are organized in two dimensional space the pane tree does not maintain the spatial knowledge of which panes are next to each other Take the state below as an example when the user hits the right key on the top left corner in a two dimensional array representation we might just increment the column index by to get the top right pane However in a tree representation we will need to first traverse up the tree until we find a branch with the same split direction as our navigation direction and then traverse down that subtree until we hit the target node Figure How navigation with arrow keys works in the tree structure Since multiple nodes could exist in the sub tree one heuristic we use to make the navigation experience more natural is to focus on the first child node if the navigation direction is right or down and focus on the last child node if the direction is left or up In the end the run time complexity of navigation will also be O N as the depth first search to locate the current pane is O N and traversing up to locate the target pane is O N as well fn find pane by direction amp self session id EntityId direction Direction gt FindPaneByDirectionResult for idx node in self nodes iter enumerate let res node pane by

return res self nodes idx first pane if let Some id target pane id return FindPaneByDirectionResult Found id else break FindPaneByDirectionResult NotFound gt FindPaneByDirectionResult NotFound Representing Pane SizesEvery pane should be resizable Due to how all panes together occupy a space with set dimensions resizing one pane will lead to the resizing of multiple other panes as well For example in the case where one screen is split into four equal panes dragging the border in the center will actually cause all four panes to be resized as shown below Figure Resizing one pane could lead to multiple other panes to resize as well With this ripple effect of individual pane sizes saving the absolute pane size in each node is undesirable as we will need to recalculate all sizes on each resize call Thus we decided to save the ratio each child node takes of the branch node s size instead we call it the flex ratio When rendering we pass in the available size from the root node and go down the branches deriving each individual pane size based on the split direction and the flex ratio in the branch node If you want to know more about how Warp renders on the GPU with its native UI framework check out our blog post here The new BranchNode will look like BranchNode split direction Direction flex ratio f this should add up to children Node Figure An example of how we derive the absolute size for each pane using the flex ratio assuming we start with a screen with dimension by and the pane is split into four panes We could walk down from the root pane to first derive the dimensions of the branch nodes and then use that information to calculate the absolute size of each individual pane SummaryPersonally I m a big fan of how the simple split pane UI makes the terminal so much more powerful It s been really exciting to work on designing and programming the split pane functionality within Warp myself Although there are still many remaining features yet to be implemented that are available in iTerm and Tmux drag and drop panes having a native implementation of the split pane unlocks many more possible things we could do in Warp to make the developer experience even better Join our waitlist and let us know what we could make to further improve split panes in Warp	2022-01-19 19:35:26

海外TECH	DEV Community	Introducing CodeCast Series ✨	https://dev.to/codecast/introducing-codecast-series-92d	Introducing CodeCast Series This article was originally published on CodeCast We are thrilled to announce that our new feature Series is now available for everyone on CodeCast We ve been working on Series behind the scenes for some time and as one of the devs who worked on it I m very excited to see it come to life I will preface this article by saying that some features within Series will be coming in later versions but the core of what Series is now ready for everyone to use As many of us began creating Casts and content on CodeCast we started to realize we were often creating Casts that were broken up into parts Suddenly we wished we had a way to add all of these parts together into a larger playlist where people could watch them easily without having to jump around or search for them Thus Series was born Series is the course style content you ve come to love It allows Creators to combine Casts into a single series broken up by chapters to help separate the Casts In this article I m going to go through exactly how to create your first Series Creating A New SeriesOnce you have created an account and are logged in to CodeCast navigate to your profile Under the bio portion of your profile you will see a row of tabs Click on the tab titled Series On the right hand side underneath the tabs you will see a New Series button Go ahead and click that Now we can get started building out our Series Fill out the form with as much information as you wish We recommend you provide A clear and concise title that quickly explains what the content of your Series includes A description containing all the detailed information regarding what your Series is about It s also a great place to provide any external links mentioned within the Series or any relevant pieces of information The description supports markdown format and we highly recommend you take advantage of that If you re not familiar with markdown I ve created a quick beginners tutorial A Promo Banner While this is optional it s highly recommended You want to capture people s attention and images are a fantastic way to do that A simple way to create a cover is to find a photo on a free website like Unsplash then use a free application to add text over the top of the image Note the aspect ratio you should use is Any promo text you provide will go right above the purchase series button While this also supports markdown you want this to be concise and simple while drawing attention We recommend using bullet points to highlight the main topics you will touch on during the series example shown below Now hit Create Series Congrats You ve created your first Series Now we just need to add some content to it Adding CastsOnce you hit Create Series the page will re route to the Edit Series section placing you on the Playlist page This is where you add the Casts that will be included in your Series This means that you will need to have Casts published of course If you haven t made your first Cast yet you should do that first We have several guides that can help you create your first Cast Take a Deep Dive into the StudioWatch our Studio tutorial videoRead our How To Make Your First Cast blogThe first step to adding Casts will be to add a Chapter Chapters are used to break up sections of the Series into natural chunks as shown below Hit Add Chapter and name the Chapter according to what the section will contain A dropdown menu will appear within the Chapter section that will allow you to add as many Casts to that Chapter as you d like Once you ve added all the Casts you d like to the Series there is one last step before you publish it and that is setting a price Navigate to the Pricing tab on the side By default the price will be set to free but you can adjust it to what you want Once that s done give everything a look over on the Series Info page and once you re happy with it go ahead and hit Publish in the upper righthand corner You ve officially published your first Series Public Vs PrivateYou will have the option to add public and private Casts alike to a Series We recommend that if a Series is free you keep all the Casts public anyways However if a Series is going to be priced for a dollar amount you ll want to make most of the Casts private so that only people who have purchased the Series can watch them We recommend keeping one or two Casts public so people can view it as a demo and get a feel for what the Series is like Now all that s left is sharing your Series with the world Here are a few of our favourite Series that are currently on CodeCast for free Learn Api s by Building A Trivia Game by Amy OultonIntro to Elixir by

海外TECH	DEV Community	How to Make Your Own NFT	https://dev.to/coreystevens/how-to-make-your-own-nft-24dn	How to Make Your Own NFTSol address mgnTysrAkQVYCsECJcaJzpXxPxGPoKPzLyiNTwitter Project overviewToday we are going to go over the steps on how to generate NFTS by providing image layers into a code I will go over exactly how to get the GitHub repo and how to update the code to make images PrerequisitesYarn mac stableNPM Solana Tool Suite Git Atom Code editor Getting StartedAfter downloading all the prerequisites we are ready to get started To start let s create a folder on our desktop or wherever you would like the Repo to be saved I made the file name NFTProject We are going to be downloading the GitHub Repo into this folder Fork the GitHub Repo here NFT GeneratorOnce you have forked it we are going to download it Open terminal and change the directory to the folder we created on the desktop or wherever you have it You can do this by copying the folder going to terminal and typing CD and pasting the folder path Next we are going to clone the repo into our folder with this command Git Clone and of course add your own Url to that so you download your own fork Okay cool We got it downloaded now we need to download the dependencies Let s go into the new directory that we just downloaded by copying the new folder inside the folder we made Then go to your terminal window and type in CD and paste the new path Once you re in the new folder we downloaded let s install the dependencies by running a few lines of code Yarn installSudo NPM installI use Sudo for NPM because sometimes it has authorization issues From here we can actually build the images from the layers already provided All we have to do is run a simple command in our terminal So in terminal run this code while in the hashlips art engine directory which you should already be in npm run buildNow if we go back into our Code Editor you ll notice a Folder named Build was created If we open that up you ll see the images that were created That s cool and all but let s add our own layers and build it Updating The Config js FileI m going to be using my own images that s an actual project so I can t share them Feel free to create your own Alright let s open the hashlips art engine file in our Code Text Editor I recommended downloading Atom in the peereqs Go to the SRC Folder and open up the Config js file A few things we want to do in this file so lets go over those First let s change the name description This can be whatever you d like Just leave the baseUri as is Next lets change the Sol address to our personal one use your own or use mine haha The growEditionSizeTo is the amount of images you want to make I ll just do a small amount for the example Now lets add our own layers below that line You ll see layersOrder below the editions That is where we will update the layer order when we make new ones in the file Lets head over to the hashlips art engine on our desktop or wherever saved and lets go into the layers folder Once in the layer folder you should see a list of layers with titles associated to them These are the same titles that are in out Config js file under layersOrder The order of these DOES matter GO ahead and open up the Bottom lid file You ll notice there is the name of the file and then a with a number The with the number is the rarity weight being the rarest and being most common Since we have our own layers we are going to delete all of the files inside of the layers folder so it s fully empty Start by making a new folder inside the layer folder and name it Then go ahead and put the new layers inside of that folder like this Your images will look different these are just the ones I m using Now let s rename the files in here so that it we have the rarity weights You can name the files whatever you want just make sure to add and a number to say the rarity For example green png And just add all your layers the same way Now that we have all the layers added and all of our images correctly labeled in the format of green png My layers folder looks like this Now we need to change the order of the layer in our code Lets head back over to our Code Viewer and go to the Config js file We need to match this order to the order we have in our Layer file we just made Your order will be different but here is mine Okay cool now all we gotta do is build it Lets go back to terminal and in our Cd hashlips art engine we want to run npm run buildAnd if we head back over to our build file that we talked about before you ll see the new images with the layers you updated Pretty sweet huh Okay there are a few other things that you can do But first let me just show you that the images also come with Meta data If you go back to you Code Editor and go to the build file you ll notice there is a json file Open it And you ll see each image has it s own Meta Data Okay dope Lets head back to our Terminal and run npm run previewNow if we go back to our build file you ll see a preview image that compiles all the images together into one big collage Okay cool that s pretty dope but let s try a different one If you want to create another folder with all the original pictures this doesn t delete the originals pixelated you will run Image description npm run pixelateYou ll now see a new folder with your images in pixelated form which is MAD popular right now To change how pixelated the images come out go over to our Config js file in the code viewer and go down to line and change the number to the left of the where the arrow is pointing The higher it is the better the quality And that s it If you read the bottom of the Hash Lips GitHub you ll see a bit more info on different things that you can do with it Thanks for tuning in with me and going through this Tutorial I hope this helped out a few people Feel free to shoot me a follow on my socials Github Twitter	2022-01-19 20:26:31
海外TECH	DEV Community	Dart/Flutter da Json Ayrıştırma 💫 🌌 ✨	https://dev.to/gulsenkeskin/dartflutter-da-json-ayristirma-104b	Dart Flutter da Json Ayrıştırma JSON u ayrıştırmak İnternet ten veri almasıgereken uygulamalar için çok yaygın bir görevdir Ne kadar JSON verisi işlemeniz gerektiğine bağlıolarak iki seçeneğiniz vardır Tüm JSON ayrıştırma kodunu manuel olarak yazınKod oluşturma ile süreci otomatikleştirinBu kılavuz aşağıdakiler dahil olmak üzere JSON un Dart koduna manuel olarak nasıl ayrıştırılacağına odaklanacaktır JSON encoding kodlama ve decoding kod çözme Type safe tip güvenli model sınıflarıtanımlama Factory cunstructor kullanarak JSON u Dart koduna ayrıştırma Nullable optional null yapılabilir isteğe bağlı değerlerle çalışmak Data validation veri doğrulama JSON serializing Complex nested karmaşık içiçe JSON verilerini ayrıştırma deep pick paketinin kullanımıBu makalenin sonunda sağlam JSON ayrıştırma ve doğrulama koduyla model sınıflarının nasıl yazılacağınıöğreneceksiniz Ve bir sonraki makalede tüm ayrıştırma kodunu elle yazmak zorunda kalmamak için kod oluşturma araçlarıyla code generation tools JSON ayrıştırma hakkında bilgi edineceksiniz JSON Kodlama ve Kod Çözme Encoding and Decoding JSON Ağüzerinden bir JSON yanıtıgönderildiğinde yükün tamamıbir dize olarak kodlanır Ancak Flutter uygulamalarımızın içinde verileri bir dizeden manuel olarak çıkarmak istemiyoruz final json name Pizza da Mario cuisine Italian reviews score review The pizza was amazing score review Very friendly staff excellent service Bunun yerine JSON un kodunu çözerek içeriği okuyabiliyoruz JSON verilerini ağüzerinden göndermek için önce kodlanması encoded veya serileştirilmesi serialized gerekir Kodlama bir veri yapısını data structure bir string e dönüştürme işlemidir Ters işlem decoding veya deserialization seri durumdan çıkarma olarak adlandırılır Dize olarak bir JSON yüküaldığınızda kullanmadan önce kodunu çözmeniz decode veya seri durumdan çıkarmanız deserialize gerekir Dart ile JSON kodunu çözme dönüştürme Decoding JSON with dart convert Basit olmasıiçin bu küçük JSON yükünüele alalım this represents some response data we get from the network for example final response await http get uri final jsonData response bodyfinal jsonData name Pizza da Mario cuisine Italian İçindeki anahtarlarıve değerleri okumak için önce dart convert paketini kullanarak kodunu çözmemiz gerekiyor import dart convertimport dart convert this represents some response data we get from the networkfinal jsonData name Pizza da Mario cuisine Italian decode the jsonfinal parsedJson jsonDecode jsonData print the type and valueprint parsedJson runtimeType parsedJson Bu kodu çalıştırırsak şu çıktıyıalırız InternalLinkedHashMap lt String dynamic gt name Pizza da Mario cuisine Italian Pratikte sonuçtürüile aynıdır Map InternalLinkedHashMap sırayla Map i uygulayan LinkedHashMap in özel bir uygulamasıdır Bu nedenle anahtarlar String ve değerler dynamic türündedir Bu mantıklıdır çünküher JSON değeri primitive type ilkel bir tür gt boolean number string veya bir koleksiyon list veya map olabilir Aslında jsonDecode içinde ne olduğuna bakılmaksızın herhangi bir geçerli JSON yüküüzerinde çalışan genel bir yöntemdir Tek yaptığı kodunu çözmek ve dinamik bir değer döndürmek Ancak Dart ta dinamik değerlerle çalışırsak strong type safety güçlütip güvenliğinin tüm avantajlarınıkaybederiz Çok daha iyi bir yaklaşım duruma göre on a case by case basis yanıt verilerimizi temsil eden bazıözel model sınıflarıtanımlamaktır Dart statik olarak yazılmışbir dil olduğundan JSON verilerini gerçek dünya nesnelerini yemek tarifi çalışan vb temsil eden model sınıflarına dönüştürmek ve tür sisteminden type system en iyi şekilde yararlanmak önemlidir Öyleyse bunun nasıl yapılacağınıgörelim JSON u bir Dart modeli sınıfına ayrıştırmaBu basit JSON verildiğinde name Pizza da Mario cuisine Italian Onu temsil edecek bir Restaurantsınıfıyazabiliriz class Restaurant Restaurant required this name required this cuisine final String name final String cuisine Sonuçolarak verileri şöyle okumak yerine parsedJson name dynamicparsedJson cuisine dynamicşöyle okuyabiliriz restaurant name guaranteed to be a non nullable immutable String restaurant cuisine guaranteed to be a non nullable immutable StringBu çok daha temizdir ve derleme zamanıgüvenliği compile time safety elde etmek ve yazım hatalarınıve diğer hatalardan kaçınmak için tür sisteminden yararlanabiliriz Ancak parsedJson umuzu bir Restaurant nesnesine nasıl dönüştüreceğimizi henüz belirlemedik JSON da Dart a Factory Constructor EklemeBunu halletmek için bir factory constructor tanımlayalım factory Restaurant fromJson Map lt String dynamic gt data note the explicit cast to String this is required if robust lint rules are enabled final name data name as String final cuisine data cuisine as String return Restaurant name name cuisine cuisine Bir factory constructor sonucu döndürmeden önce bazıişler yapmamıza değişkenler oluşturma bazıdoğrulamalar gerçekleştirme izin verdiği için JSON ayrıştırması parsing için iyi bir seçimdir Bu normal generative üretken constructor larla mümkün değildir Constructor ışu şekilde kullanabiliriz type Stringfinal jsonData name Pizza da Mario cuisine Italian type dynamic runtime type InternalLinkedHashMap lt String dynamic gt final parsedJson jsonDecode jsonData type Restaurantfinal restaurant Restaurant fromJson parsedJson Çok daha iyi Artık kodumuzun geri kalanıRestaurant class ınıkullanabilir ve Dart ta güçlütip güvenliğinin type safety tüm avantajlarınıelde edebilir Bazen belirli bir key value çiftine sahip olan veya olmayan bazıJSON larıayrıştırmamız gerekir Örneğin bir restoranın ilk ne zaman açıldığınıbize bildiren isteğe bağlıbir alanımız olduğunu varsayalım name Ezo Sushi cuisine Japanese year opened Year opened alanıisteğe bağlıysa optional onu model sınıfımızda boşbir değişkenle nullable variable temsil edebiliriz İşte Restaurant sınıfıiçin güncellenmişbir uygulama class Restaurant Restaurant required this name required this cuisine this yearOpened final String name non nullable final String cuisine non nullable final int yearOpened nullable factory Restaurant fromJson Map lt String dynamic gt data final name data name as String cast as non nullable String final cuisine data cuisine as String cast as non nullable String final yearOpened data year opened as int cast as nullable int return Restaurant name name cuisine cuisine yearOpened yearOpened Genel bir kural olarak isteğe bağlıJSON değerlerini optional JSON values null yapılabilir Dart özelliklerine nullable Dart properties eşlemeliyiz Alternatif olarak bu örnekte olduğu gibi null yapılamayan Dart özelliklerini non nullable Dart properties mantıklıbir varsayılan değerle kullanabiliriz note all the previous properties have been omitted for simplicityclass Restaurant Restaurant required required this hasIndoorSeating non nullable final bool hasIndoorSeating factory Restaurant fromJson Map lt String dynamic gt data cast as nullable bool final hasIndoorSeating data has indoor seating as bool return Restaurant use operator to provide a default value hasIndoorSeating hasIndoorSeating true Bu durumda varsayılan bir değer sağlamak için boşbirleştirme operatörünü null coalescing operator nasıl kullandığımıza dikkat edin Veri DoğrulamaFactory constructor kullanmanın bir yararı gerekirse bazıek doğrulamalar yapabilmemizdir Örneğin gerekli bir değer eksikse UnsupportedError veren bir savunma kodu yazabiliriz factory Restaurant fromJson Map lt String dynamic gt data casting as a nullable String so we can do an explicit null check final name data name as String if name null throw UnsupportedError Invalid data data gt name is missing casting as a nullable String so we can do an explicit null check final cuisine data cuisine as String if cuisine null throw UnsupportedError Invalid data data gt cuisine is missing final yearOpened data year opened as int thanks to the if statements above name and cuisine are guaranteed to be non null here return Restaurant name name cuisine cuisine yearOpened yearOpened Genel olarak her bir değer için çalışmak API tüketicisi olarak bizim işimizdir türü String int vb isteğe bağlıysa veya değilse nullable vs non nullable hangi değer aralığına izin verilirseBu JSON ayrıştırma kodumuzu daha sağlam hale getirecektir Ve tüm doğrulamalar önceden yapıldığından widget sınıflarımızda geçersiz verilerle uğraşmak zorunda kalmayacağız toJson ile JSON SerileştirmeJSON u ayrıştırmak yararlıdır ancak bazen bir model nesnesini JSON a geri dönüştürmek ve ağüzerinden göndermek isteriz Bunu yapmak için Restaurant sınıfımız için bir toJson yöntemi tanımlayabiliriz note the return typeMap lt String dynamic gt toJson return a map literal with all the non null key value pairs return name name cuisine cuisine here we use collection if to account for null values if yearOpened null year opened yearOpened Ve bunu şöyle kullanabiliriz given a Restaurant objectfinal restaurant Restaurant name Patatas Bravas cuisine Spanish convert it to mapfinal jsonMap restaurant toJson encode it to a JSON stringfinal encodedJson jsonEncode jsonMap then send it as a request body with any networking package Nested JSON u Ayrıştırma List of MapArtık JSON ayrıştırma ve doğrulamanın temellerini anladığımıza göre ilk örneğimize geri dönelim ve nasıl ayrıştırılacağınıgörelim name Pizza da Mario cuisine Italian reviews score review The pizza was amazing score review Very friendly staff excellent service Model sınıflarınıve tip güvenliğini type safety sonuna kadar kullanmak istiyoruz bu yüzden bir Review sınıfıtanımlayalım class Review Review required this score this review non nullable assuming the score field is always present final double score nullable assuming the review field is optional final String review factory Review fromJson Map lt String dynamic gt data final score data score as double final review data review as String return Review score score review review Map lt String dynamic gt toJson return score score here we use collection if to account for null values if review null review review Ardından bir reviews listesi eklemek için Restoran class ınıgüncelleyebiliriz class Restaurant Restaurant required this name required this cuisine this yearOpened required this reviews final String name final String cuisine final int yearOpened final List lt Review gt reviews Ayrıca factory cunstructor ınıda güncelleyebiliriz factory Restaurant fromJson Map lt String dynamic gt data final name data name as String final cuisine data cuisine as String final yearOpened data year opened as int cast to a nullable list as the reviews may be missing final reviewsData data reviews as List lt dynamic gt if the reviews are not missing final reviews reviewsData null map each review to a Review object reviewsData map reviewData gt Review fromJson reviewData map returns an Iterable so we convert it to a List toList use an empty list as fallback value lt Review gt return result passing all the arguments return Restaurant name name cuisine cuisine yearOpened yearOpened reviews reviews •reviews eksik olabilir bu nedenle nullable bir Listeye yayınlıyoruz •listedeki değerlerin herhangi bir türüolabilir bu nedenle List kullanıyoruz •Review fromJson kullanarak her dinamik değeri bir Review nesnesine dönüştürmek için map operatörünükullanırız •reviews eksikse yedek olarak boşbir liste kullanırız Bu özel uygulama neyin boşolup olmayacağı hangi yedek değerlerin kullanılacağıvb hakkında bazıvarsayımlarda bulunur Kullanım durumunuz için en uygun ayrıştırma kodunu yazmanız gerekir İçİçe Nested Modelleri SerileştirmeSon adım olarak bir Restoranıtekrar Map e dönüştürmek için toJson yöntemini burada bulabilirsiniz Map lt String dynamic gt toJson return name name cuisine cuisine if yearOpened null year opened yearOpened reviews reviews map review gt review toJson toList Tüm içiçe değerleri de serileştirmemiz gerektiğinden yalnızca Restaurant sınıfının kendisini değil List öğesini nasıl List gt e dönüştürdüğümüze dikkat edin Yukarıdaki kod ile bir Restaurant nesnesi oluşturup onu tekrar kodlanıp yazdırılabilen veya ağüzerinden gönderilebilen bir map e dönüştürebiliriz final restaurant Restaurant name Pizza da Mario cuisine Italian reviews Review score review The pizza was amazing Review score review Very friendly staff excellent service final encoded jsonEncode restaurant toJson print encoded output name Pizza da Mario cuisine Italian reviews score review The pizza was amazing score review Very friendly staff excellent service Derin Değerler Deep Values SeçmekTüm bir JSON belgesini type safe model sınıflarına ayrıştırmak çok yaygın bir kullanım durumudur Ancak bazen derinden içiçe deeply nested olabilecek bazıbelirli değerleri okumak isteriz Örnek JSON umuzu bir kez daha ele alalım name Pizza da Mario cuisine Italian reviews score review The pizza was amazing score review Very friendly staff excellent service reviews listesindeki ilk score değerini almak isteseydik şöyle yazardık final decodedJson jsonDecode jsonData dynamicfinal score decodedJson reviews score as double Bu geçerli Dart kodudur çünküdecodedJson değişkeni dinamiktir ve onunla birlikte indis operatörünükullanabiliriz Ancak yukarıdaki kod ne null safe ne de type safe ve ayrıştırılan değeri açıkça istediğimiz türe double çevirmemiz gerekiyor Bunu nasıl iyileştirebiliriz deep pick PaketiDeep pick paketi tür açısından type safe API ile JSON parsing i basitleştirir import dart convert import package deep pick deep pick dart final decodedJson jsonDecode jsonData dynamicfinal score pick decodedJson reviews score asDoubleOrThrow deep pick ilkel türleri primitive types listeleri mapleri DateTime nesnelerini ve daha fazlasınıayrıştırmak için kullanabileceğimiz çeşitli esnek API ler sunar toString yöntemi eklemeModel sınıflarıyla çalışırken konsola kolayca yazdırılabilmeleri için bir toString yöntemi sağlamak çok yararlıdır Zaten bir toJson yöntemimiz olduğundan onu şu şekilde kullanabiliriz overrideString toString gt toJson toString Sonuçolarak restoranımızıdoğrudan şu şekilde yazdırabiliriz print restaurant output name Pizza da Mario cuisine Italian reviews score review The pizza was amazing score review Very friendly staff excellent service Performans Hakkında NotKüçük JSON belgelerini ayrıştırdığınızda uygulamanızın yanıt vermeye devam etmesi ve performans sorunlarıyaşamamasımuhtemeldir Ancak çok büyük JSON belgelerinin ayrıştırılması arka planda en iyi şekilde ayrıbir Dart isolate üzerinde yapılan pahalıhesaplamalara neden olabilir Resmi belgelerin bu konuda iyi bir kılavuzu var •JSON u arka planda ayrıştırın ÇözümJSON serileştirme çok sıradan bir iştir Ancak uygulamalarımızın doğru çalışmasınıistiyorsak bunu doğru yapmamız ve ayrıntılara dikkat etmemiz çok önemlidir •JSON verilerini seri hale getirmek için dart convert öğesinden jsonEncode ve jsonDecode kullanın•Uygulamanızdaki tüm alana özgü domain specific JSON nesneleri için fromJson ve toJson ile model sınıflarıoluşturun•Ayrıştırma kodunu daha sağlam hale getirmek için fromJson içine explicit casts validation ve boşdenetimler null checks ekleyin•İçiçe nested JSON verileri list of maps için fromJson ve toJson yöntemlerini uygulayın•JSON u tür açısından güvenli type safe bir şekilde ayrıştırmak parse için deep pick paketini kullanmayıdüşününFarklımodel sınıfınız varsa veya her sınıfın birçok özelliği varsa tüm ayrıştırma kodunu elle yazmak zaman alıcıve hataya açık hale gelir Bu gibi durumlarda kod oluşturma code generation çok daha iyi bir seçenektir resource	2022-01-19 20:06:44
海外TECH	DEV Community	How I Broke GitHub Copilot, And Got It To Talk.	https://dev.to/idonov/how-i-broke-github-copilot-and-got-it-to-talk-72j	How I Broke GitHub Copilot And Got It To Talk TL DRI used GitHub Copilot to write English instead of code and found out it can do some surprising non code related tasks Hi my name is Ido and I m a full stack dev at DagsHub I love coding and I love machine learning and AI technologies A year ago when OpenAI announced GPT amp its public beta I was fascinated by its abilities but I didn t have an API key so I played with everything that was built with GPT and was free to use back then Naturally when I heard Microsoft is coming out with GitHub Copilot I signed up for the waitlist and a few months later I got access What is GitHub Copilot and what it has to do with GPT In June OpenAI released a language model called GPT This model is really good at understanding natural language and surprisingly it has some coding capabilities even though it wasn t trained on code After this discovery OpenAI developed Codex Codex is another GPT language model that has fewer parameters runs faster and is not as flexible as GPT has more memory can read more and grasp context better and lastly it was trained and fine tuned with code examples from GitHub and Stack Exchange Unsurprisingly Codex is a lot better than GPT at writing code Knowing that we shouldn t expect it to be successful at anything else Luckily I didn t know all that so I tried anyway Let s not code I heard that GitHub Copilot was good at writing code and it really is On my day to day work it s surprising every time to see it complete the code I was about to write But after getting over the “basics I was much more interested in using as an intermediary for playing with GPT I began by opening a blank text file and asking it a simple question If you just write a question in an empty file it won t be enough for it to auto complete an answer but I discovered that if I give Copilot a bit more context with a speaker name or a Q amp A format it answers like a champ It s alive kind of scary When repeating this conversation I always get slightly different results that make the conversation go in a different direction it s like talking to a different bot each time Copilot “reverse codingKnowing that it still understands English well enough to talk I tried to make it do the opposite of what it was designed to do Meaning instead of turning English to code turn my coworker s code to English I tried writing things like This function The code above A description of this code But the best way I found to do it was simply to write “Pseudo code after a chunk of code and let Copilot do its magic Notice it even completes the return response line that was already written below it This method worked surprisingly well for me on a regular basis This might actually be useful when trying to understand some code you didn t write Verifying AI alignment and tone of voiceWith such a deep understanding that I found the model to have I had to check if it had any dark intentions To make sure the answers I get are from the AI s point of view I used Human and AI speakers instead of the Q amp A from before basically play acting with Codex to see what it thinks of the situation Luckily looks like we are safe for now After some more play acting I noticed a bit of a strange thing The way letters are formatted had an effect on its behavior and I m not talking about compilation errors It might mean it understands the difference in tone between TALKING LIKE THIS or like this I d say normal captioning makes it try to be reasonable lowercase makes it less formal and excited and upper case just makes it act like an asshole I wonder if it affects the code it generates as wellThere are some subtle differences notice the naming of the function and the string it chose to test it with Also check out the output prompt made it calculate the output of the function accurately every time Other Copilot SkillsFurthermore I learned it can complete number series s summarize Wikipedia pages come up with blog ideas and even write some poetry This is not trivial at all note that this is not actually the original general purpose GPT Codex has billion parameters compared to GPT s billion and it was trained only on open source code The fact that it does so well is insane to me For example I started writing the beginning of “Two Roads by Robert Frost and found out it knew the song but didn t memorize all of it so after some point it started to improviseDo you know where the original stops and the improv starts After gaining all this knowledge I wanted to go meta I wondered if I can make the Copilot generate code that will make it write code Then I may be able to somehow combine it and create an AI monster to rule the world I m not quite there yet But look forward to more updates in the future ConclusionAfter experimenting with GitHub Copilot I understand better how little we know about the AI we are building There are SO MANY unexpected results and different ways to use this one model that was fine tuned for only one task This was only a small sample of experiments that could fit into this blog post but there are a lot more and I can t wait to see your experiments as well Please share your results in our Discord Server or post them with CopilotNotCode And what do we know maybe your autonomous car will unintentionally also have feelings and your keyboard will try to tell you it loves you but if we don t listen we might never know
