Opacc Scripting VS Code Extension 26.1

A Visual Studio Code extension for Opacc BlockScript and F-Script with syntax support, completions, hover documentation, signature help, templates, snippets, and quick access to Opacc manuals.

Successor of the legacy Opacc F-Script and Opacc BlockScript extensions

This extension supersedes the legacy "Opacc F-Script" and "Opacc BlockScript" extensions. If one of the legacy extensions is still installed, it can conflict with this extension.

Features

Language support

• Syntax highlighting for Opacc BlockScript
• Syntax highlighting for Opacc F-Script, including embedded BlockScript blocks
• Built-in language configuration for indentation, folding, bracket behavior, and editor defaults tailored to both languages
• Automatic saving of BlockScript and F-Script files as UTF-8 with BOM

Note: Full syntax highlighting is only available when using the included Opacc theme. Some highlighting details may not look correct with other themes.

IntelliSense and documentation

• Code completion for BlockScript snippets
• Code completion for Block functions
• Code completion for APS functions
• Code completion for Application Objects
• Hover documentation for Block functions, APS functions, IBOS commands, Application Objects, and built-in snippet content
• Signature help for Block functions and APS functions in BlockScript
• Signature help for IBOS calls and Application Object calls in F-Script
• Scope-aware behavior in F-Script: BlockScript assistance is offered inside embedded block scopes, while F-Script specific IBOS and Application Object help is offered outside those scopes
• Documentation links from hover and completion items, with support for opening manuals in the integrated browser, an embedded view, or the external browser

Snippets and templates

• Templates for new BlockScript files and new functions
• Static F-Script snippets for common script structures, conditions, comments, services, libraries, and APS functions
• Function-style completions can be shown either as plain functions or as snippets with pre-filled argument placeholders

Productivity commands

• Search in Opacc Manuals Search the manuals from the editor context menu or command palette. The command uses the selected text when present, otherwise it prompts for input.
• Search & Insert Function / IBOS / Object Search across Block functions, APS functions, IBOS commands, and Application Objects, then insert the selected item directly at the cursor.
• Paste as variable assignment code Convert comma-separated clipboard content into variable assignment code for either BlockScript or F-Script. The command adapts to the current scope and can generate GetColValByName(...), XQRS(...), or XRES(...) patterns.

Theme

• Includes the Opacc dark theme

Notes

• In F-Script files, BlockScript completions and hovers are only active inside embedded block scopes.
• Application Object and IBOS assistance is focused on regular F-Script code outside embedded block scopes.
• The extension also applies editor defaults such as UTF-8 BOM encoding, folding support, tab size, and quick suggestions for both supported languages.

🎉 Happy scripting!
