GDL Syntax Highlighter for Sublime Text is a developer tool providing syntax highlighting and autocompletion for ArchiCAD GDL scripting. This package integrates directly into the Sublime Text editor to provide a dedicated environment for writing Geometric Description Language (GDL) scripts. It features structured syntax highlighting, which colour-codes commands, variables, and parameters to improve readability during complex object development. The tool includes pre-configured snippets and automated code completion, designed to accelerate the creation of parametric BIM components. By streamlining the text-based editing process, it allows developers to focus on logic and geometry definition rather than syntax errors, effectively turning a general-purpose text editor into a specialised development environment for ArchiCAD library parts.

The download is a 154 KB file containing .ZIP files.

Installation involves adding the package to the Sublime Text user directory, allowing the editor to recognise GDL file extensions automatically. Once configured, developers can open existing GDL scripts to benefit from real-time syntax checking and code hinting. The tool helps maintain clean, structured code, which is essential when managing large libraries of parametric objects. It is best utilised alongside the ArchiCAD GDL editor for testing and debugging, providing a more robust text-editing experience throughout the object development lifecycle.

Engineers and BIM managers developing custom parametric library parts for ArchiCAD will find this tool essential for efficient scripting. It is intended for use in professional office environments where high-volume object creation and maintenance are required. By providing a more stable and feature-rich editing platform than the default internal editor, it supports the development of complex, data-rich BIM assets. This tool is ideal for architectural practices, furniture manufacturers, and MEP consultants who need to standardise their internal library content development workflows.
