Examples in README fail due to clojure.lang.Named cast exception about jmh-clojure HOT 2 CLOSED

Hello there. Thank you for the interest!

The problem here, as you correctly stated, is that jmh.core/run expects data, not fns. This is due to how the generated classes must be compiled to be used with JMH.

In the example code from the README, the data in question is read from the benchmarks.edn file via clojure.edn/read-string, which returns simple data. In the case of the :fn values, namespaced symbols and a list of two symbols and a number: (partial * 0.5). The symbols are later resolved, and the expression data is later evaluated in a JMH subprocess before running the benchmarks.

I wrote a short article here that describes a simplified model of this process if you're curious.

Thank you for opening this issue, however. I don't think I made this as clear as I should have. The exception should also be more descriptive of the actual problem. I have updated the README and added stricter checking of the :fn values.

Does the above sufficiently address this issue in your opinion? Also, please feel free to ask if you have any questions. Thanks again!

Much better. Thanks again, it’s working very nicely for me so far. I’m looking forward to adding lots of tests to my benchmark suite.
