Getting Started with dharam-gfx

Let's dive into the steps to create your first VS Code theme using dharam-gfx. This process involves setting up your development environment, creating your theme file, and testing your creation within VS Code.

Project Setup

Start by creating a new directory for your VS Code theme project:

mkdir my-theme
cd my-theme

Initialize a Node.js project within the directory:

npm init -y

Install the dharam-gfx library:

npm install dharam-gfx

Theme File Creation

Create a new file named theme.js within your project directory. This file will house the code for your theme:

// theme.js
const dharamGfx = require('dharam-gfx');

// Define your theme colors
const colors = {
  background: '#f0f0f0',
  foreground: '#222',
  selectionBackground: '#e0e0e0',
  activityBarBackground: '#eee',
};

// Create a theme instance
const theme = new dharamGfx.Theme(colors);

// Set your theme properties
theme.set('editor.background', colors.background);
theme.set('editor.foreground', colors.foreground);
theme.set('editor.selectionBackground', colors.selectionBackground);
theme.set('sideBar.background', colors.activityBarBackground);

// Export the theme object
module.exports = theme;

Theme Testing in VS Code

To test your theme, you need to load it within VS Code. Follow these steps:

Open VS Code and navigate to File > Preferences > Settings.
Search for "extensions" and select "Extensions: Show Built-in Extensions".
Find the "Themes" extension and click "Enable".
Open the Command Palette (Ctrl+Shift+P or Cmd+Shift+P) and search for "Themes: Apply Theme".
Choose "Themes: Apply Theme" and select your theme from the list.

You should now see your theme applied to your VS Code editor. Adjust the colors and properties within theme.js and reload your VS Code window to see the changes.

Diving Deeper: dharam-gfx Features

The dharam-gfx library provides a wealth of features to customize your VS Code themes. Here's a breakdown of some key functionalities:

Color Manipulation

dharam-gfx offers a comprehensive API for color manipulation. You can:

Define Colors: Use various formats for defining colors, including hex codes, RGB values, and color names.
Create Color Palettes: Organize your colors into palettes for easier management and consistency.
Adjust Brightness and Contrast: Fine-tune color brightness and contrast to enhance readability and visual appeal.
Generate Color Schemes: dharam-gfx can help you create harmonious color schemes based on your primary color choice.

Font Customization

In addition to colors, dharam-gfx allows you to customize fonts for your theme. You can:

Set Font Families: Choose from a wide range of font families for your code editor, ensuring optimal readability and visual consistency.
Control Font Size: Set the font size for different elements of your editor, such as code, comments, and headings.
Adjust Font Weight: Make code more prominent by increasing the font weight for keywords and variables.

Advanced Theme Options

dharam-gfx empowers you to customize a wide range of theme properties beyond colors and fonts. You can:

Control Visual Styles: Customize the appearance of the code editor, sidebars, and other UI elements.
Manage Token Colors: Define the colors for different code elements, such as keywords, variables, and comments.
Customize Highlight Rules: Control the way syntax highlighting is applied to different code elements.
Create Custom Themes: Build themes for specific languages or frameworks, tailored to your coding style.

Example: Creating a Monochromatic Theme

Let's create a simple monochromatic theme using dharam-gfx. This theme will use a single color with variations in lightness and saturation to create visual hierarchy.

theme.js

const dharamGfx = require('dharam-gfx');

// Define the primary color
const primaryColor = '#333';

// Generate a color palette
const colors = dharamGfx.createPalette(primaryColor);

// Define the theme properties
const theme = new dharamGfx.Theme(colors);

theme.set('editor.background', colors.lightest);
theme.set('editor.foreground', colors.darkest);
theme.set('editor.selectionBackground', colors.lighter);
theme.set('sideBar.background', colors.light);
theme.set('editor.selectionHighlightBackground', colors.medium);

// Export the theme object
module.exports = theme;

This example demonstrates the power of dharam-gfx's color palette creation. By defining a single primary color, we can generate a set of variations that provide visual contrast and depth to our theme.

Building Your VS Code Theme Extension

Now that you have a theme file, you can package it into a VS Code extension for easy distribution and use.

Create the Extension Folder

Create a new folder named extension within your theme project. This folder will house your extension files:

mkdir extension
cd extension

Extension Manifest

Create a package.json file within the extension folder. This file defines the metadata for your extension:

{
  "name": "my-theme",
  "displayName": "My Theme",
  "description": "A custom VS Code theme created with dharam-gfx.",
  "version": "1.0.0",
  "publisher": "your-publisher",
  "engines": {
    "vscode": "^1.67.0"
  },
  "categories": [
    "Themes"
  ],
  "activationEvents": [
    "onCommand:my-theme.activate"
  ],
  "main": "./extension.js",
  "contributes": {
    "themes": [
      {
        "label": "My Theme",
        "uiTheme": "vs-dark", // Or 'vs-light'
        "path": "../theme.js"
      }
    ]
  }
}

Extension Activation Script

Create a file named extension.js within the extension folder. This script activates your theme when the extension is loaded:

// extension.js
const vscode = require('vscode');

function activate(context) {
  console.log('Congratulations, your extension "my-theme" is now active!');
}

exports.activate = activate;

Packaging the Extension

Use the vsce command-line tool to package your extension. Ensure vsce is installed globally. You can find installation instructions here: https://code.visualstudio.com/api/working-with-extensions/publishing-extension

Navigate to the extension folder and package the extension:

vsce package

This will create a VSIX file containing your theme extension. You can now install this VSIX file in VS Code by dragging and dropping it into the editor window or using the VS Code Extension Manager.
