https://clojurians.slack.com/archives/C04CAKAGADU/p1757685501508859?thread_ts=1757684821.897969&cid=C04CAKAGADU It's my understanding that there's no way to set the source name and line number without using Compiler/load. It would be great to be able to include meta data like source, line, col, and more when evaling individual forms. Specifically, this comes up when trying to map exceptions and https://docs.oracle.com/en/java/javase/21/docs/api//java.base/java/lang/StackTraceElement.html back to source code.

One simple example of the difference between cider-eval-defun-at-point and cider-load-buffer

(throw (Exception. "This is from cider-eval-defun-at-point"))

Execution error at com.phronemophobic.easel/eval123716 (REPL:1263).
This is from cider-eval-defun-at-point

(throw (Exception. "This is from cider-load-buffer"))

Execution error at com.phronemophobic.easel/eval125489 (easel.clj:1263).
This is from cider-load-buffer

@alexyakushev is eval-fn usually set? I assume this doesn't work with eval and you need to use Compiler/eval?

oyakushev 2025-09-16T17:15:04.844679Z

I think we only use eval-fn in load-file middleware, and only started doing that recently

oyakushev 2025-09-16T17:15:11.213669Z

It works with regular eval

oyakushev 2025-09-16T17:15:34.597379Z

If you open the sources for Compiler.load, binding the dynvars is the only interesting thing it does.

ok, interesting. Thanks for the tip
