Picceler Language Support for Visual Studio Code

Official syntax highlighting and language configuration for Picceler—a custom DSL for image processing and hardware acceleration.

Features

Describe specific features of your extension including screenshots of your extension in action. Image paths are relative to this README file.

• Syntax Highlighting: Rich tokenization for Picceler functions (def, return), comments (#), strings, numbers, and operators.
• Types: int64, float64, string, image, kernel are highlighted as storage.type — most themes (including VS Code's built-in Dark+) render this in blue.
• Built-in Dialect Ops: Full highlighting for native image processing intrinsics, scoped as support.function.builtin.* — most themes render this in yellow:
  • I/O & Utilities: load_image, save_image, show_image, print, read_string, read_number
  • Math: sqrt, pow
  • Filters: brightness, invert, sharpen, box_blur, gaussian_blur, edge_detect, emboss, rotate
  • Algorithms & Morphology: convolution, erode, dilate, diff, blend, crop
• Language Intelligence: Hover docs, signature help (parameter hints while typing a call), and snippet completion for every builtin function — e.g. typing box_blur( shows box_blur(image img, int64 radius) -> image. This is static (a hardcoded table, not real type-checking), so it can't catch a wrong-typed argument, only show the expected shape.
• Language Integration: Automatic file detection for .pic scripts, comment toggling (#), and auto-closing bracket/quote pairs.

Requirements

• No external runtime or Node.js dependencies are required for syntax highlighting!
• To compile .pic source files, ensure you have the picceler binary installed and accessible in your system path.

Extension Settings

• This extension does not contribute any custom configuration settings. Syntax highlighting relies on native VS Code tokenization (the TextMate grammar); hover/signature-help/completion are provided by a small bundled extension.js (no third-party dependencies).

Known Issues

• None reported at this time. If you run into syntax rendering issues or missing ops, feel free to open an issue on the repository!

Release Notes

See CHANGELOG.md for release notes.

Publishing

Releases are published manually — see HOWTO.md for how to package and publish a new version.

Developer note

• AI Assistance: This extension, its syntax highlighting configurations, and supporting scripts were built with heavy reliance on AI tools.
• Asset Credits: The extension icon was generated using AI.
• Design Philosophy: Written as a pragmatic wrapper to handle basic editor tooling and language support for Picceler—because spending hours manually writing boilerplate editor extensions by hand isn't worth the time.

Please Enjoy!
