Improvement of OpenSCAD Text-Editor Features

As modern OpenSCAD usage has advanced, it now makes more extensive use of libraries consisting of many files, and the editor features have not kept pace with this more advanced workflow. The goal of this project will be to add different IDE-like features to the integrated text editor thus advancing its usage. This will make the editor more user-friendly and easier to handle large codes. Currently, the editor supports features like syntax highlighting, bracket matching, numbering of lines, besides others. I will work on implementing multi-file editing support to the editor and autocompletion of OpenSCAD keywords.
