Wvlet for VS Code

This extension provides syntax highlighting and language support for the Wvlet query language in Visual Studio Code.

Features

• Syntax Highlighting: Full syntax highlighting for .wv files including:

  • Keywords and control structures
  • Data types and type annotations
  • Operators and expressions
  • String literals with interpolation support
  • Numeric literals (integers, floats, hex)
  • Comments (single-line -- and multi-line ---)

• Language Configuration:

  • Bracket matching and auto-closing
  • Comment toggling
  • Word pattern recognition

• Language Server:

  • Inline compilation diagnostics (errors and warnings as you type)
  • Document outline (models, types, vals, and flows)
  • Code completion for keywords, in-file models, and column names
  • Hover with type information for columns and expressions, and signatures for models and types
  • Go-to-definition for models and types

  Language server features currently resolve symbols within the same file only.
