They also built a minimal [Processing LSP client for VSCode](https://github.com/kgtkr/processing-language-server-vscode).\n-   Further work by @efratror was included in Processing 4.3 (see https://github.com/processing/processing4/issues/678 and https://github.com/processing/processing4/issues/690)\n-   As part of the `pr05` grant in 2024, @diyaayay worked on another [VS Code extension](https://github.com/diyaayay/processing-language-server-extension) though it did not make use of the built-in LSP.\n\n### Proposed Improvements\n\nWe’d like to improve and extend the current functionality of the built-in LSP.  Priorities are:\n\n- [ ]    Display parameter names in function signatures  (e.g., `copy(sx, sy, sw, sh, dx, dy, dw, dh)`) should show named parameters\n- [ ]    \"Go to declaration\" for built-in functions and classes  (linking to Processing source code when possible)\n- [ ]    Hover documentation for built-in functions and core classes\n- [ ]    Support for overloaded functions  (e.g., `colorMode(mode)`, `colorMode(mode, max)`, `colorMode(mode, max1, max2, max3)`)\n\nIf you're interested in contributing or discussing further, feel free to comment here. \n\nThanks again to everyone who has contributed to this work so far!","author":{"url":"https://github.com/SableRaf","@type":"Person","name":"SableRaf"},"datePublished":"2025-04-16T13:10:06.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":12},"url":"https://github.com/1041/processing4/issues/1041"}
