✨ Features

🎨 Smart Formatting

Multi-language — VBScript, HTML, CSS, JavaScript, and SQL in a single keystroke
VBScript — smart indentation across all control structures and multi-block <% %> regions
HTML/CSS/JS — formatted by Prettier, fully configurable
Keyword casing — your choice of PascalCase, UPPERCASE, or lowercase

💡 IntelliSense & Auto-Completion

Context-aware — correct suggestions whether you're in ASP, CSS, JS, or HTML
COM object tracking — type rs. after Set rs = Server.CreateObject("ADODB.Recordset") to see all methods and properties
Cross-file IntelliSense — variables and functions from #include'd files appear in suggestions automatically
File paths — live browsing inside #include and href/src/action attributes

🔍 Hover, Definition & Links

Hover docs — inline documentation for keywords, functions, COM members, and CSS properties
Go to definition — F12 across the current file and all included files
Document links — Ctrl + Click navigation on #include paths and local file attributes

🌈 Syntax Highlighting

ASP regions — toggleable background colouring for <% %> blocks, light and dark themes
Semantic colouring — user-defined functions and sub names
Smart SQL — highlights SQL inside strings; plain strings are left untouched

🔴 Diagnostics

HTML — mismatched structural tags flagged with orange squiggles
VBScript — unmatched control blocks (If/End If, Sub/End Sub, For/Next, etc.)
CSS — errors and warnings inside <style> blocks as you type
Void elements — invalid closing tags caught with a one-click quick fix

⌨️ Smart Key Handling

Context-aware Enter/Tab — correct indentation inside <% %> blocks automatically
Auto de-indent — closing keywords (End If, Next, etc.) de-indent as you type
Auto-close — HTML and ASP comment blocks close automatically
