I’m not sure which Python library or tool would be best for this. I’ve heard about tools like Pylint and Pylance, but I couldn’t find any clear documentation or examples showing how to use them for real-time syntax checking in a GUI application. Most of what I’ve found is about running them from the command line or integrating with VSCode Also i have tried: I looked into using pylint, but the documentation doesn’t show how to extract errors from a code string directly. I also explored ast and compile() for basic syntax checking, but I’m unsure how to extract line/column info and types of errors for highlighting. Any suggestions, libraries, or code examples would be really helpful Continue reading...
