Code Transformer

"Code Transformer" is a Visual Studio Code extension that allows you to transform or process code by executing custom JavaScript expressions or preset expressions.

Features

Basic Usage

No configuration is required. Simply use the transform code extension command to manually input an expression.

Parameters

The parameters that can be used in the expression are:

• s: Current line of text
• l: Current line number
• f: Built-in function object

Example: Reverse the current line of text

1. Select the line of text you want to process.
2. Open the command palette and execute the transform code extension command.
3. In the input box that appears, type s.split('').reverse().join('').
4. After execution, the selected line of text will be reversed.

Advanced Usage

1. Using Built-in Functions

You can configure built-in functions in the settings panel to call these functions in expressions.

Example: Configure a built-in function to transform text to snake_case

1. Open settings and navigate to the Code Transformer settings.
2. In the "Built-in Functions" section, add a new function, for example:

[
    {
        "name": "toSnakeCase",
        "code": "(str) => { return str.replace(/([A-Z])/g, '_$1').toLowerCase(); }"
    }
]

3. Save the settings.
4. Now you can use f.toSnakeCase(s) in the input box for the transform code extension command or in preset expressions.

2. Using Preset Expressions

You can configure preset expressions in the settings panel for quick selection and execution.

Example: Configure a preset expression

1. Open settings and navigate to the Code Transformer settings.
2. In the "Preset Expressions" section, add a new expression, for example:

[
    {
        "name": "toSnakeCaseExp",
        "code": "f.toSnakeCase(s)"
    }
]

3. Save the settings.
4. Now you can open the list of preset expressions (quickPick) via the transform pick extension command and choose this preset expression for execution.
