Provide or explain how to get completion in Clojure socket REPLs

[arichiardi]

It looks like what inf-clojure currently uses for completions has been abandoned (aka feature complete?).

Cider uses the wonderful https://github.com/alexander-yakushev/compliment and we probably should as well. It gives you more completion power as well because it accepts a context in input, which it then uses to complete locals, for instance.

It also returns more metadata together with the actual completion and we could feed that to company-mode.

That's because REPLy uses the old completion library internally and it's always available to users of boot and leiningen (which use REPLy). The only real fix for this is to finish somehow trptcolin/reply#153

[arichiardi]

I see, I opened this because I had some exception and I basically realized that according to your message I don't have any completion in boot when using a socket repl. That's where the exception comes from.

When you can easily add a check for the presence of compliment and use different completion commands for it. That'd be simple approach to solve this problem.

Compliment sends back edn. So I am thinking we could have a var containing a function which is called with whatever the completion command returns. This function would be user provided (with a default), to that the passing of the compliment's edn can be done (potentially using parseclj.

Or a different module inf-clojure-company can provide this function for company-mode for instance.

Yeah, that sounds like a good approach to me. edn.el (https://github.com/expez/edn.el) can also be used (at least temporary, until parseclj gets a stable release).

I am working on a solution for this, it will require compliment on the classpath.
