for example, I can place the cursor on the name of a function and ask “where is this defined”, and it jumps to the place of the definition, which could be in my own code or in third party code. But I can also ask “where is this function called” or “where is this variable referenced”. This is extremely useful for code refactoring and it beats every “modern” IDE I’ve seen.
This is an odd statement. Visual Studio has been around for umpteen years and has always had these features.
I am not sure when the “jump to” stuff was added in Emacs, but VS was released in 1997, or, when Emacs was old enough to drink beer in the USA. :D
It’s one thing to claim that lisp/emacs was first (although “first” by itself is not much relevant at this late stage), but it’s definitely incorrect to claim this feature doesn’t exist elsewhere. Instead of convincing me that lisp is great, I’m convinced of the author’s own inexperience.
but it’s definitely incorrect to claim this feature doesn’t exist elsewhere
I don’t recall that being claimed. Totally agree though, “first” has little relevance beyond giving me the opportunity to allude to the fact that emacs is an alcoholic.
I’m not sure how else to interpret the claim that it beats every other IDE. It doesn’t seem to be saying that the find references feature works better in some way. It’s saying that the existence of the feature is what beats other IDEs, implying they don’t have it.
