Page dies with "Error: timeout" on OS X

[s1341]

I tried installing the latest release, and building from source. In both cases, when I pipe anything to page I get the text "Error: Timeout" and neovim exits.

[s1341]

Ok. Compiled neovim from source and that seems to fix it.

[s1341]

Nope. I was wrong. Compiling neovim from source did NOT fix this issue.

Sorry, for delayed response.

I don't have access to any OS X machine, so I cannot debug it by myself.

Could you redirect to page with RUST_LOG=trace RUST_BACKTRACE=1 and provide output?

Does it work with TMPDIR=/tmp set when redirecting to page ?

[s1341]

nope. Same error

I've got the same error, also on macOS. Not sure what's happening though, but wanted to corroborate what @s1341 is saying.

[I60R]

There are two problems with macOS:

1. Seems like a bug in FSEvents (page uses it to await until neovim's socket becomes available).
   Create events for sockets and pipes are swallowed, only Remove are delivered
   

2. Don't allows to find actual path to PTY device associated with :term buffer.
   On Linux it's possible to obtain /dev/pty/* by following /dev/stdout symlink but on macOS it only produces fd/1 which of course isn't useful for page.

---

So, both of them will require some hacks to allow page to work properly on macOS.

---

Edit:

Actually there's a way to resolve /dev/pty/* path. Neovim :term buffer provides channel property, and there's nvim_get_chan_info() function which allows to get info about channel. This info contains "pty" property

[I60R]

Here is a new release v2.0.0 where all MacOS problems are fixed (at least for me - tested it on MacOS run in VirtualBox).

Thank you for reporting this!

[s1341]

Confirmed working. Thanks for the prompt fix!

[JeanMertz]

Works for me as well. Awesome, and thank you 👍

The latest release gives me the same bug again, Error: timeout. v2.3.5 still works for me though. (I haven't tested versions in between.)
