Vscode generate getters and setters python

This is my class called manager I want to generate automatically getter and setter in python vs code.

class Manager:
    def __init__[self, name, salary, bonus]:
        self.bonus = bonus
        self.__salary = salary
        self.name = name
    def show_info[self]:
        print["Name: ", self.name]
        print["Salary: ", self.__salary]
        print["Bonus: ", self.bonus]
    
    def give_bonus[self]:
        print["You have received a bonus of ", self.bonus]

manager = Manager["Kamran", 10000, 5000]
manager.show_info[]
manager.give_bonus[]

I know in intellij idea. In your project, right-click anywhere on the typing screen, and click 'Generate...' and then 'Getter and Setter'. Then, hold down CTRL and click on the fields you wish to create getters and setters for, then click on 'OK'.

public class People {
    private String name;
    private int age;
    private String language;

    /**
     * @return String return the name
     */
    public String getName[] {
        return name;
    }

    /**
     * @param name the name to set
     */
    public void setName[String name] {
        this.name = name;
    }

    /**
     * @return int return the age
     */
    public int getAge[] {
        return age;
    }

    /**
     * @param age the age to set
     */
    public void setAge[int age] {
        this.age = age;
    }

    /**
     * @return String return the language
     */
    public String getLanguage[] {
        return language;
    }

    /**
     * @param language the language to set
     */
    public void setLanguage[String language] {
        this.language = language;
    }
}

###Introduction If you hate stubbing out Python classes, here’s how you can create an extension in Visual Studio Code to do it for you. In this article, you’ll see how to create that extension. We will use several techniques to do so.

• Prompting User Input
• Array Map and Join Functions
• ES6 Template Literals
• Writing to the File System

You’ll create a new extension, prompt the user for input, convert the input to a string that represents the new class file, and write out the result.

Creating the Project

To get started with developing Code extensions, you’ll need two different NPM packages installed, “yo” and “generator-code”.

To generate your project, run the following command.

yo code

This will follow up by asking you several questions about your project. Choose either JavaScript or TypeScript for your extension.

After answering all of the questions, open the newly created project in VS Code.

You’ll have a several different files created for you, the two most important are the package.json and extension.js files.

Start by opening the extension.js file. Then, rename the extension command name to createPyClass.

Then, in the package.json file, rename the activation event and command to match the name of the command.

Update the title as well, which is what the user will type to activate the command.

To run the extension, open the debug panel [looks like a bug] and press play. This will open up a new instance of VS Code. Open the command prompt [Command+Shift+P on Mac and Control+Shift+P on Windows] and type “Create Python Class”.

And you should see the “Hello World” message.

Prompt the User for Input

We need to prompt the user for input about the class [class name and properties] and convert that input into a string that we can write to the new class file.

Let’s start by ensuring the user has a folder currently open. If not, we don’t have a place to write the new class file to. If the user does not have a folder open, we show an error message and return.

if [!vscode.workspace.workspaceFolders] {
  return vscode.window.showErrorMessage[
    "Please open a directory before creating a class."
  ];
}

Now, we can ask the user for the name of the class they want to create. If the user, for some reason, closes the input prompt [by hitting escape] we return.

const className = await vscode.window.showInputBox[{
  prompt: "Class Name?"
}];

if [!className] return;

We want to let the user input as many properties as they want to. For this we prompt initially for a property, then run a while loop retrieving properties until the user enters “done”.

let count = 1;
let property = await vscode.window.showInputBox[{
  prompt: `Property #${count}? ['done' when finished]`
}];
const properties = [];
while [property != "done"] {
  properties.push[property];
  count++;
  property = await vscode.window.showInputBox[{
    prompt: `Property #${count}? ['done' when finished]`
  }];
}

Rerun your extension, enter in valid inputs, and print the user’s info to be sure it looks right.

Create the Class Content String

Now, we start to take the user’s input to generate the content of the class. Let’s start by creating the class definition line as well as the constructor definition.

const classDefinition = `class ${className}:`;
const constructorDefinition = `def __init__[self, ${properties.join[", "]}]:`;

Then, we can create the constructor assignments lines. This is where the user will initialize variables on itself, using the values of the constructor parameters. For this, we use map [as we will from now on] to convert each of the property inputs in some way.

const constructorAssignments = properties
  .map[property => `self.${property} = ${property}\n\t\t`]
  .join[""];

Now, for each property, we create a getter function. Again, we use map to convert each property into a string that represents its getter.

const classGetters = properties
  .map[
    property => `\tdef get_${property}[self]:\n\t\treturn self.${property}\n\n`
  ]
  .join[""];

The last thing we want to create is the string function that will tell Python how to print this object. Again, we use the map function to convert each property by printing the name of the property and then its value.

Notice that in the map return value, we are adding a comma and a plus. This means for the last property, we would be adding unnecessary characters at the end. For this reason, we convert the resulting array to a string and chop off the last 11 characters by using splice.

const dunderStrString = `\tdef __str__[]:\n \t\treturn ${properties
  .map[property => '"' + property + ': "' + " + " + property + ' + " , " + ']
  .join[""]
  .slice[0, -11]}`;

Let’s take this individual pieces and put them all together!

const classString = `${classDefinition}
    ${constructorDefinition}
        ${constructorAssignments}
${classGetters}
${dunderStrString}`;

Create a log statement and run this again to make sure your class string looks good.

Creating the Class File

Now, we need to write that string to a new file. To work with files, we need to import the “fs” and “path” modules from Node at the top of the page.

const fs = require["fs"];
const path = require["path"];

Then, we need to get the path for the user’s currently open directory. You can get a reference to open directories by vscode.workspace.workspaceFolders. Then, we get the first one from the resulting array, grab its URI, and convert it to a string. The resulting path string included a prefix, so we strip that out by splitting on a colon and grabbing what comes after the colon.

const folderPath = vscode.workspace.workspaceFolders[0].uri
  .toString[]
  .split[":"][1];

Now we can use the fs module, the folder path, and the name of the class file, to write the class string to our new file.

fs.writeFile[path.join[folderPath, `${className}.py`], classString, err => {}];

We can take it one step further by providing the user some feedback based on whether or not the write file was successful.

fs.writeFile[path.join[folderPath, `${className}.py`], classString, err => {
  if [err] {
    vscode.window.showErrorMessage["Something went wrong"];
    return console.log[err];
  }
  vscode.window.showInformationMessage[`${className} Class created.`];
}];

Run It

Either refresh your debugging instance or start again by following the steps above. With the debug instance of VS Code open, run your “Create Python Class” command again. Then, enter the name of the class you want to create. “Person” in this case.

Then enter your properties, “name” first.

Then “age”.

Then “done” to finish.

The file is successfully created.

Then, double check your file was actually created and it looks good
