Work over stdio? #65
Description
Activity
Thanks!
A stdio transport is on the roadmap; in fact, it was the first transport I expected to deliver. I switched to TCP because I was able to get better performance out of it. I'll revisit the stdio implementation and post updates in this issue.

Reacted by Faris MasadThe
stdiobranch includes a working implementation of the stdio transport. Runsolargraph stdioto start the server. The performance issues I encountered in my earlier experiments appear to be largely resolved here. I haven't benchmarked it, but its performance "feels" very close to the socket server.I encourage client developers to clone/fork it and give it a try. Barring major bugs, I expect to publish it in gem version 0.23 or 0.24.

If anyone has any problems using the stdio transport, please open a new issue.

Hey! This is awesome! I'm using https://github.com/onivim/oni and would love to use this with it, but Oni only supports stdio for language servers at the moment: could you make solargraph work over stdio as well as it's current TCP setup? My naive self tells me this should be relatively trivial to impliment.
