@dominicm async-clj-omni is supposed to work wither with fireplace or acid?

I'm getting error about missing acid.nvim

With either, yes. Is the error from deoplete?

https://github.com/clojure-vim/async-clj-omni/blob/master/rplugin/python3/deoplete/sources/acid.py#L68

Init should only be called if the source is being loaded (I think?)

I think the code in that line itself is bad

on_init is called always

there is no way to prevent it being called

And either echom call works correctly and for some reason it shows as a error when called from python code

Or that echom call is bad and that is why I get an error

anyway, I don't think it should try to give a message about installing acid.nvim

I did look at few other deoplete sources and I think they generally just do nothing if something is missing

Though some of those are packaged together with the "main plugin" which either provides everything or displays the errors

vim.call is wrong there because takes function as the first argument and parameters as varargs

self.vim.eval('echom "Acid.nvim not found. Please install it."')

should be correct here, I think

but for some reason that throws even bigger error

Ah no, echomsg is not a vimscript function but ex command: self.vim.command('echomsg "Acid.nvim not found. Please install it."')

this will correctly only output the message instead of throwing error

It's weird, I don't get that message, and don't have acid installed.

__init__ is always called. So I think on_init must be different somehow

Might be because I specify which sources to use for clojure, so it's a manual list..
