Bklang Language Support for Visual Studio Code

Official high-performance Visual Studio Code extension for Bklang (.bkl files), providing syntax highlighting, intelligent code completion, rich parameter & documentation hovers, standard library snippets, and document symbol outlines.

✨ Features

• 💡 Intelligent IntelliSense & Autocompletion:

  • Contextual completions for keywords (fn, struct, class, if, for, while, try, catch, pipe).
  • Native Standard Library function signatures with inline parameter details and usage examples.
  • Automatic detection and completion of local user-defined variables, functions, and structs across the active document.

• 🎨 TextMate Syntax Highlighting:

  • Full-color grammar parsing for types (int, str, float, bool, auto, array, map), function definitions, pipeline operators (|>), lambda arrows (=>), f-strings (f"..."), numbers, and comments (//, #, @...@).

• 📖 Rich Hover Documentation:

  • Instant tooltips displaying type signatures, descriptions, and code examples for all standard library functions (Math, Strings, JSON, Crypto, File System, OS).

• ⚡ Productivity Snippets:

  • Rapid code templates: fn (Function), pfn (Pipeline function), cls (Class), struct (Data record), trycatch (Error handling), json (Serialization block), and doc (Docstrings).

• 🔍 Document Outline & Symbols:

  • Full support for the VS Code Outline view and Quick Open (Ctrl+Shift+O / Cmd+Shift+O) to jump directly to any function, class, struct, or top-level variable.

Example .bkl Program:

// Hello Bklang
str name = "Developer";
print f"Welcome to Bklang, {name}!";

// Pipeline processing
auto numbers = [1, 2, 3, 4, 5];
auto result = numbers
    |> filter((x) => x % 2 != 0)
    |> map((x) => x * 10);

print f"Transformed values: {json_stringify(result)}";
