Flow does not see my code, instrumentation seems to do nothing

[holyjak]

Hello! I am just trying Flow 2.2. with my lein-based project and having some issues with it.

I have added a #trace in front of a function and evaluated it and then #rtrace in front of a expression that I then evaluated. Then:

1. A flow-0 opens with the expression but nothing else and next to the navigation buttons there is 0/-.
2. When I go to Browser I see Instrumentations is empty. If I find the target fn manually and click the [Instrument] button on it, in the REPL I get "Couldn't find source for /". Re-running the r-traced expression opens the non-flow tob tab with a thread-77 sub-tab with the code of the target function but agai njust 0/- and not more data anywhere.

Any idea what could I be doing wrong? Thank you!

Hi @holyjak !

Do you have a link to the code you are trying to instrument, or maybe you can paste here some forms?
Does the basic example on the Readme works for you?

Seeing 0/- is expected behavior if you haven't made the first step, when you advance the debugger one step it should show the amount of traces you got for that thread.

Sorry, I was wrong! I did not understood that I have to press the ▶️ button to start seeing stuf. I expected to see 0/<a positive int> or perhaps even the first (0th?) trace. Thank you!

Great! no problem.
Yeah I agree that is confusing. I left the total traces like that for now just for performance reasons.
Just modifying that javafx Label on every new trace was making things slow when I was getting 50 million traces at 200k traces per second. But will revisit that soon.
If you have any other issues I just created the #flow-storm slack channel on clojurians.
