I/O error while reading marker byte: failed to fill full buffer about neovim-lib HOT 4 CLOSED

Of course. I completely forgot that rpc communication happens via stdout/stdin.
Removing the println! indeed resolved this bug. I kind of feel stupid about this one.
Sorry for causing you any inconvenience and thanks for helping and for providing this library!

from neovim-lib.

I've seen this error often, and always in the following 2 circumstances:

• A neovim misfeature (which limited message size to 10MB, fixed now to be 2GB)
• I made a mistake which made neovim hang up the channel

First, I'd look at the log of a debug build of neovim built with MIN_LOG_LEVEL=0 to see if that tells you anything.

But I see in your case there's an error in there that tells you that you sent something wrong. I could not perform a proper analysis now, but I'd BET that println! wreaks havoc with running rpc over stdin/stdout (don't ask how often I've made that mistake).

I can confirm the error reported disappears when the following patch to remove the only println!() is applied.

Could you provide a list of steps to reproduce?

Also, since you continue to make changes, could you post which revision exhibited this behavior? Your recent change to rename ctrlp.vim to ctrlprs.vim breaks the init.vim which still sources the old filename.

After correcting the filename in init.vim, I tried these steps.

# At shell prompt.
nvim -u init.vim

# In neovim v0.3.4.  Initialize ctrlp-rs.  The line after is an echoed result.
:call ctrlprs#init()
ctrlp error: stderr

# Check messages.

I'm obviously missing something in order to reproduce your error, but I'm not sure what.

Update 1

The following patch fixed the No such file or directory error.
