Hi, I am a rookie to Racket. Recently I am debugging a Racket program, which depends on several other packages. I found it difficult to locate the definition for each function. The only way I know is using "trace". But that is not so convenient since I need to first change "define" to "trace-define". Is there any easy way to quickly find the location of function definitions? Thanks!

What editor are you using?

If you're using DrRacket, you can right-click on an identifier, and often you will have a context-menu item "Open defining file". And if this file is already open in DrRacket, you may even have on right-click "Jump to definition (in other file)".

Thanks! I was working with command line, and did not realize DrRacket is so powerful!

Similarly, vim with LSP support (_e.g._, via ALE) and `racket-langserver` can jump to definition.
