Thanks for asking. I've been meaning to address these kinds of questions in the aider FAQ [0]. Here's the entry I just added:
Aider supports pretty much all the popular coding languages. This is partly because GPT-4 is fluent in most mainstream languages, and familiar with popular libraries, packages and frameworks.
In fact, coding with aider is sometimes the most magical when you're working in a language that you are less familiar with. GPT often knows the language better than you, and can generate all the boilerplate to get to the heart of your problem. GPT will often solve your problem in an elegant way using a library or package that you weren't even aware of.
Aider uses tree-sitter to do code analysis and help GPT navigate larger code bases by producing a repository map [1].
Aider can currently produce repository maps for most mainstream languages, listed below. But aider should work quite well for other languages, even without repo map support.
