Look at your dependencies. I had an issue where my java jdk was basically broken (java's fault, not mine, in so far as the code is concerned). I ended up using the latest OpenJDK (number 15). That worked. If you get lots of java specific type errors and those errors change with the versions that you're using, then consider updating your java jdk. I was using LTE versions before and the latest fixed it.

It is definitely possible, although it might take more work than simply adding another function. You will need to first define two helper traits that specify the mapv and powi (much like Squared) operations for both f64 and Array1:

I think the "No such var" error is happening because the tokenizer is an anonymous function.

If you had the default tokenizer defined as a non-anonymous function in flexsearch.core and then used that name in the test, it would work.

However, in general, you cannot compare two functions for equality - as @cfrick says. When you are comparing maps, where some of the values are functions, you are still comparing functions.

You have correctly discovered how *err* is initialized, but since vars are rebindable this is no guarantee about its current value. The REPL often rebinds it to something else, e.g. a socket. If you want to redirect it yourself, you should simply rebind *err* to a Writer of your choosing.

Really I'm not sure your approach would work even if *err* were never rebound. The Clojure runtime has captured a pointer to the original value of System.err, and then you ask the Java runtime to use a new value for System.err. Clojure certainly won't know about this new value. Does the JRE maintain an extra level of indirection to allow it to do these swaps behind the scenes even for people who have already captured System.err? Maybe, but if so it's not documented.

Metabase is an actively maintained project with some great people working full time on it. And adding features is what makes opensource magic. With projects like this it's almost always easier to work with the existing people to add new things.

1. check if just using your browsers print-to-pdf function is good enough.
2. start by checking the github page for open or closed project issues page about this:
3. Contact the metabase folks (some of whom are likely to see this message) and tell them what you want. Offer your help and ask where the best place to start is.
4. get the metabase development environment setup by following these instructions
5. read these instruction and especially the contributing guide. Then open a PR for what you are working on. Don't just call them up with a completed new feature. Communicate early and often.
6. Add your export feature to the backend export section and the frontend page
7. Add UI tests and tests for the backend.
8. Don't sweat it when there are many rounds back and forth to get the PR in a state for being merged. It's not a critisism of you to make the code fit nicely.

The return value that you say you would like is not a legal map, because it has multiple occurrences of the key :pageID and multiple occurrences of the key :outpages. Clojure maps (and their corresponding things in most programming languages, e.g. dictionaries in Python) have at most one occurrence of each key.

If you update what you want as a return value to something that is a valid Clojure data structure, someone may be able to help with the code.

I'm unable to reproduce your problem. I'm using regular Java. I have your exact Python Lambda and have have a Runnable:

No need for Spectre on this one. Just use basic Clojure:
