Those numbers are written into the bytecode, and they’re basically always correct. However, they’re correct for the moment at which you compile a particular piece of code, which in the case of Clojure means when you sent it to the REPL. So in particular, if you’re editing functions and then sending them to the REPL, odds are that the lines compiled into the functions appearing after the ones you sent are now incorrect. The safest thing to do is to send the entire namespace before debugging.

Hi Collin is it cursive who is responsible for writing these into the byte code, or is that some magic of the jvm or intelliJ?

I believe my byte-code line numbers must be wrong from the outset, because I don't think I'm doing any redefinitions in the repl.

my suspicion is that cursive is assuming the package name is the same as the file name.

however, it might be that java/maven/intelliJ is making this assumption.

@U064X3EF3 Any idea if there are bugs around this? This project has an unusual layout, e.g. https://gitlab.lrde.epita.fr/jnewton/clojure-rte/-/blob/180118911e37024c9216bd05b9fee93a327095bf/src/clojure_rte/api.clj, where in-ns is used to define things in the core ns from other files.

Doesn’t ring a bell but could be
