A comprehensive VSCode extension that provides syntax highlighting and intelligent autocompletion for Viewi PHP/HTML components.

• PHP expressions in HTML: Highlights PHP code within { } and {{ }} braces
• Viewi components: Special highlighting for component tags (PascalCase tags)
• PHP variables and functions: Proper syntax highlighting for PHP expressions in HTML templates

• Component tags: Autocomplete component names when typing < in HTML files
• Cross-project discovery: Automatically finds all Viewi components across the project

• Property completion: Autocomplete public properties from the corresponding PHP component class
• Method completion: Autocomplete public methods with parameter hints
• Trigger on {: Automatically suggests expressions when typing opening braces
• Context-aware: Only shows relevant completions based on the current component

• Automatically detects PHP/HTML component pairs (same base name, same location)
• Links HTML templates with their corresponding PHP component classes

Viewi components consist of two files:

• ComponentName.php - Contains the PHP class with the component logic
• ComponentName.html - Contains the HTML template

HomePage.php:

<?php

namespace Components\Views\Home;

use Viewi\Components\BaseComponent;

class HomePage extends BaseComponent
{
    public string $title = 'Viewi - Reactive application for PHP';
    public bool $isLoading = false;
    
    function getName(): string
    {
        return 'HomePage';
    }
    
    function getTitle(): string
    {
        return $this->title;
    }
}

HomePage.html:

<div class="home-page">
    <h1>$title</h1>
    <p>Loading: {$isLoading ? 'Yes' : 'No'}</p>
    <p>Component: {getName()}</p>
    <p>Title: {{getTitle()}}</p>
</div>

<div>
    <HomePage title="My new title" />
</div>

The extension can be configured through VSCode settings:

{
    "viewi.enableAutocompletion": true,
    "viewi.componentSearchPaths": ["."]
}

• viewi.enableAutocompletion (boolean, default: true): Enable/disable autocompletion features
• viewi.componentSearchPaths (array, default: ["."]): Directories to search for Viewi components

• Viewi: Refresh Components: Manually refresh the component cache

The extension enhances the built-in HTML language support in VS Code to provide syntax highlighting and autocompletion for Viewi components and expressions.

Autocompletion is triggered by:

• < - For component tag suggestions
• { - For PHP expression suggestions
• $ - For variable suggestions anywhere in HTML files
• CTRL + (SPACE)

1. Component Tags: Type <My → suggests MyButton, etc.
2. Variables anywhere: Type $ → suggests $title, $isLoading, etc.
3. Variables in braces: Type {$ → suggests $title, $isLoading, etc.
4. Methods in braces: Type {get → suggests getName(), getTitle(), etc.
5. Expression templates: Type { → suggests {$title}, {{$title}}, {getName()}, etc.
6. CTRL + (SPACE): All above

1. Install the extension from the VSCode marketplace
2. Open a project containing Viewi components
3. The extension will automatically detect and index your components

npm install
npm run compile

npm install -g @vscode/vsce
node_modules/.bin/vsce package

• VSCode 1.80.0 or higher
• Node.js for development

• Component discovery is currently limited to the configured search paths
• PHP parsing is regex-based and may not handle all edge cases
